DESCRIPTION

[0017] FIG. 1 is a schematic block diagram of a thermoelectric generation system 100. In one embodiment, thermoelectric generation system 100 is utilized to generate electricity at oil and gas production facilities. Heat from combustion within a boiler at a facility can be sent to thermoelectric generation system 100 for conversion to electricity. In this embodiment, thermoelectric generation system 100 can be coupled with a production facility that heats the gas to reduce emissions of gas into the atmosphere. In another embodiment, thermoelectric generation system 100 can be utilized to generate electricity at facilities having an abundance of waste heat. Thermoelectric generation system 100 includes a thermoelectric generator assembly 102, a first fluid side, herein a hot fluid side 104, and a second fluid side, herein a cold fluid side 106. Thermoelectric generator assembly 102 generates electricity from a difference in temperature between hot fluid side 104 and cold fluid side 106.

[0018] Hot fluid side 104 defines a loop that includes a first thermal heat transfer source, herein a heat source 108, such as a boiler that heats fluid (e.g., a gas or liquid) within the hot fluid side 104. Heat source 108, in one embodiment, heats fluid within the hot fluid side 104 to a temperature above 200 degrees Fahrenheit, above 400 degrees Fahrenheit, above 500 degrees Fahrenheit and/or including between 500 to 1,000 degrees Fahrenheit. In some embodiments, hot fluid side 104 includes a pump 110 and/or sink 112. Pump 110 carries fluid throughout hot fluid side 104, whereas sink 112 accepts fluid exiting hot fluid side 104. In other embodiments, pump 110 and/or sink 112 can be eliminated. In still further embodiments, multiple pumps 110 can be used.

[0019] In another embodiment, heat source 108 is generated from gas combusted using a boiler such as a low NOx (nitrous oxide) boiler to heat fluid operating above 100,000 British thermal units (BTU), above 250,000 BTUs, above 500,000 BTUs, above 1,000,000 BTUs, and/or including between 1,000,000 BTUs to 10,000,000 BTUs.

[0020] Cold fluid side 106 defines a loop that includes a second thermal heat transfer source, herein a cold source 114, such as a chiller that cools fluid (e.g., a liquid or a gas) within cold fluid side 106. In some embodiments, cold fluid side 106 includes a pump 116 and/or sink 118. Pump 116 (which may include one or more pumps) carries fluid throughout cold fluid side 104, whereas sink 118 accepts fluid exiting cold fluid side 106. In other embodiments, the cold fluid side 106 of the thermoelectric generation system 100 can include an ammonia-based fluid that can be activated using the heat returning from the hot side manifold. In other embodiments, pump 116 and/or sink 118 can be eliminated.

[0021] Hot fluid side 104 provides hot fluid to thermoelectric generator assembly 102 through a manifold assembly 120, whereas cold fluid side 106 provides cold fluid to thermoelectric generator assembly 102 through a manifold assembly 122. Fluid from both manifold assembly 120 and manifold assembly 122 is provided to cartridge assembly 124. As discussed in more detail below, cartridge assembly 124 includes one or more hot fluid paths, one or more cold fluid paths, and one or more thermoelectric module assemblies. The thermoelectric module assemblies are positioned adjacent to both a hot fluid path and a cold fluid path and generate electricity based on a difference in temperature between the hot fluid path and the cold fluid path.

[0022] Electricity from the thermoelectric module assemblies in the form of direct current (DC) can be sent to a power module (or multiple power modules) 126, which in some embodiments includes a controller, DC/DC and DC/AC inverters, battery, and/or other components. Thermoelectric generator assembly 102, in one embodiment, can generate above 2 kilowatts (kW) of electricity, above 5 kWs, above lOkWs, above 25kW, and/or including between 25 and lOOkW.

[0023] FIG. 2 is a perspective view of an example thermoelectric generator assembly 102. Thermoelectric generator assembly 102 includes a support frame 200 that supports cartridge assembly 124. Support frame 200 is further illustrated in FIG. 3 and includes side supports 254 and 256. Manifold assemblies 258 and 260 are positioned adjacent the frame 200 on either side and are fluidly coupled with the cartridge assembly 124 (e.g., through a plurality of hoses (not shown)). In another embodiment, manifold assemblies 258 and 260 can be supported directly by base 204. Manifold assembly 258 includes an ingress manifold 258 A and an egress manifold 258B. In addition, manifold assembly 260 includes an ingress manifold 260A and an egress manifold 260B.

[0024] In the embodiment illustrated, manifold assembly 258 carries fluid from one fluid side (e.g., hot fluid side 104), whereas manifold assembly 260 carries fluid from the other fluid side (e g., cold fluid side 106). In another embodiment, manifold assemblies 258 and 260 can carry fluid from both sides, for example manifold 258A can serve as an ingress manifold for a first side (e.g., hot fluid side 104), with manifold 260B serving as an egress manifold for the first side. In addition, manifold 260A can serve as an ingress manifold for a second side (e.g., cold fluid side 106), with manifold 258B serving as an egress manifold for the second side.

[0025] Cartridge assembly 124, further illustrated in FIGS. 5-8, supports a plurality of first side heat exchangers 262, a plurality of second side heat exchangers 264, a plurality of thermoelectric module assemblies 266 and a plurality of power modules 268 receiving electricity from the plurality of thermoelectric module assemblies 266. Each of the plurality of thermoelectric module assemblies 266 is positioned between a respective first side heat exchanger 262 and a respective second side heat exchanger 264. In the embodiment illustrated, cartridge assembly 124 includes twenty-nine heat exchangers, including fifteen first side heat exchangers 262 and fourteen second side heat exchangers 264. In other embodiments, cartridge assembly 124 can include at least five, at least ten, at least fifteen, at least twenty or more than thirty heat exchangers as desired.

[0026] FIG. 9 is a side view of an example assembly that includes two first side heat exchangers 262 and a second side heat exchanger 264 positioned between the two first side heat exchangers 262. Thermoelectric module assemblies 266 and power module assemblies 268 are positioned on either side of the second side heat exchanger 264.

[0027] With reference to FIG. 3, side support 254 includes a plurality of gusset plates or supports 270 supporting a mounting plate 272 and a piston assembly 276 connected to mounting plate 272. Piston assembly 276 interfaces with an outer heat exchanger 282 of the cartridge assembly 124. Similarly, side support 256 includes a plurality of gusset plates or supports 290 supporting a mounting plate 292 and a piston assembly 296 connected to mounting plate 292. Piston assembly 296 interfaces with an outer heat exchanger 302 of the cartridge assembly 124. Together, piston assembly 276 and piston assembly 296 cooperate to place pressure on cartridge assembly 124. In one embodiment, piston assembly 296 is eliminated, wherein only piston assembly 276 places pressure on cartridge assembly 124 that is counteracted by mounting plate 292.

[0028] In one embodiment, piston assembly 276 and piston assembly 296 are similarly structured. As illustrated in more detail in FIG. 4, piston assembly 276 includes an outer piston plate 278 and an inner piston plate 280. Inner piston plate 280 includes an air pressure inlet 310 and airway channels 312. Inner piston plate 280 includes a gasket 314 that interfaces with the outer piston plate 278 (e.g., an inner ring thereof). During operation, air pressure is provided to inlet 310 and travels through airway channels 312. This increased air pressure causes movement of inner piston plate 280 away from outer piston plate 278. In turn, pressure is applied to the cartridge assembly 124, delivering a desired force to maintain contact among heat exchangers within the cartridge assembly 124. In one embodiment, an actuator (e.g., an air compressor) is configured to provide pressure to the piston assembly 276 and/or piston assembly 296. This pressure assists in maintaining contact among the heat exchangers of the cartridge assembly 124.

[0029] In the illustrated embodiment, cartridge assembly 124 extends from a first end defined by outer heat exchanger 282 to a second end defined by outer heat exchanger 302. Cartridge assembly 124 includes a plurality of fasteners 320 (e.g., including rods and nuts) that pass through each of the plurality of heat exchangers 262 and 264 and secured at outer heat exchanger 282 and outer heat exchanger 302. Planar surfaces of the plurality of heat exchangers 262 and 264 are positioned to face either the first end or the second end of the cartridge assembly 124. Upon assembly, cartridge assembly 124 is positioned between piston assembly 276 and piston assembly 296 such that the piston assemblies 276 and 296 can place compressive forces upon the cartridge assembly 124.

[0030] During operation, fluid is carried from one heat transfer source (i.e., heat source 108 or cold source 114) to first side ingress manifold 258A. The first side ingress manifold 258A is fluidly coupled with each first side heat exchanger 264 (e.g., through a plurality of fluid conduits such as hoses). First side fluid is sent through the plurality of first side heat exchangers 264 and into the first side egress manifold 258B (e.g., through a plurality of fluid conduits such as hoses). In one embodiment, in a closed-loop first side, first side egress manifold 258B is fluidly coupled with a pump (e.g., pump 110) that sends fluid from first side egress manifold 258B to one heat transfer source and back to first side ingress manifold 258 A.

[0031] Similarly, fluid is carried from the other heat transfer source (i.e., heat source 108 or cold source 114) to second side ingress manifold 260A. The second side ingress manifold 260A is, in turn, fluidly coupled with each second side heat exchangers 266 (e.g., through a plurality of fluid conduits such as hoses). Fluid is sent through the plurality of second side heat exchangers 266 and into the cold side egress manifold 260B (e.g., through a plurality of fluid conduits such as hoses). In one embodiment, in a closed-loop second side, second side egress manifold 260B is fluidly coupled with a pump (e.g., pump) 116 that sends fluid from second side egress manifold 260B to one heat transfer source and back to second side ingress manifold 260A.

[0032] FIG. 9 illustrates a side view of a portion of cartridge assembly 124, including two first side heat exchangers 262A and 262B and a second side heat exchanger 264 positioned between the two first side heat exchangers 262A and 262B. First side heat exchanger 262A includes a first, major planar surface 350 and a second, major planar surface 352 opposite the first planar surface 350. In a similar manner, second side heat exchanger 264 includes a first, major planar surface 354 and a second, major planar surface 356 defined by one or more cover plates opposite the first planar surface 354. First side heat exchanger 262B also include a first, major planar surface 358 and a second, major planar surface 360 opposite the first planar surface 358. Thermoelectric module assemblies 266 and power modules 268 are positioned between first side heat exchanger 262A and second side heat exchanger 264. Additionally, thermoelectric module assemblies 266 and power modules 268 are positioned between first side heat exchanger 262B and second side heat exchanger 264.

[0033] FIG. 10 illustrates a view of planar surface 350 of first side heat exchanger 262A. As illustrated, thermoelectric module assemblies 266 and power modules 268 are mounted to planar surface 350. Thermoelectric module assemblies 266 are connected to cover plates 380 and 382 of first side heat exchanger 262A. Power modules 268 are supported on heat exchanger 262A. A plurality of connectors 390 deliver electricity generated by thermoelectric module assemblies 266 to the power modules 268. Power modules 268 can deliver electricity to one or more loads as desired. Thermoelectric module assemblies 266 and power modules 268 are mounted to heat exchanger 262B similarly. Although illustrated with twelve thermoelectric module assemblies 266 and two power modules 268 mounted to heat exchanger 262A, any number of thermoelectric module assemblies 266 and any number of power modules 268 can be utilized to harvest energy from cartridge assembly 124 and deliver power from the power modules 268 to a desired load.

[0034] Each thermoelectric module assembly 266 is mounted to a printed circuit board 392 and includes a plurality of thermoelectric generation elements 394, as illustrated. Each element 394 includes a hot side substrate, a cold side substrate, and semiconductor devices positioned therebetween. The semiconductor devices are connected to connectors 390 that carries electrons to a specified electrical load (e.g., through a power module 268). Each thermoelectric generation element 394 can be of any size or shape, including a conventional 40 mm x 40 mm size. In some embodiments depending on the size and shape of the thermoelectric generation module used, thermoelectric module assembly 266 may not require a printed circuit board.

[0035] Each of the thermoelectric elements 394, in some embodiments, can be interconnected in series, in parallel, in a combination of series and parallel, or independently connected to a power module 268. Power module 268 can operate and invert electricity using any combination of 12V DC, 24V DC, 48V DC, HOv alternating current (AC), 220v AC, 240v AC, and 480v AC in a single or split phase. In the embodiment of FIG. 10, thermoelectric elements 394 are connected in parallel. Alternatively, as illustrated in FIG. 11, thermoelectric elements 394’ are connected in senes. [0036] FIG. 12A illustrates a side view of second side heat exchanger 264 with cover plates removed, wherein other heat exchangers within cartridge assembly 124 are of similar construction. Heat exchanger 264 defines a plate 400, with one side of plate 400 forms planar surface 354 and one or more cover plates defining planar surface 356. In one embodiment, plate 400 is formed of aluminum, although other materials can be used. For example, plate 400 can be formed of a block, and features can be machined into the block using one or more material removal techniques such as milling, drilling, and others. In addition, a seal (not shown) can be positioned in channel 408 to provide a fluid tight seal between plate 400 and one or more covers that define planar surface 356. In an alternative embodiment, heat exchanger 264 is formed of a unitary body, for example, using an injection molding, casting, or additive printing technique.

[0037] Plate 400 defines an internal fluid path 430 extending from a first end 432 to a second end 434. In the embodiment illustrated, fluid path 430 includes a substantially square cross section as best illustrated in FIG. 8. Other sectional shapes can also be used. For example, fluid path 430 can include one planar surface, two planar surfaces, three planar surfaces, or four planar surfaces. In other embodiments, fluid path 430 is circular in cross section without a planar surface in cross section. First end 432 and second end 434 each include a connector to fluidly connect fluid path 430 to a manifold. For example, first end 432 can be connected to first side ingress manifold 258A, whereas second end 434 is connected to first side egress manifold 258B. In the embodiment illustrated, fluid path 430 is circuitous or serpentine shaped, including straight segments parallel to one another and carrying fluid in opposite directions (e.g., a first straight segment 436 and a second straight segment 438) and connected through U-shaped ends (e.g., a U-shaped end 440). Other structures for fluid path 430 can also be used. Plate 400 further includes a plurality of apertures 450 configured to accommodate rods to secure heat exchanger 264 to cartridge assembly 124. During use, fluid path 430 carries fluid from first end 432 to second end 434.

[0038] In an alternative embodiment of a heat exchanger 264’ illustrated in FIG. 12B, first end 432’ and second end 434’ are positioned on opposite sides of plate 400’. Fluid path 430’ is similarly constructed to fluid path 430, with a serpentine shape. In one example embodiment, first end 432’ can be connected to ingress manifold 258A on and second end 434’ can be connected to egress manifold 260B on an opposite side of cartridge assembly 124. [0039] Various embodiments of the invention have been described above for purposes of illustrating the details thereof and to enable one of ordinary skill in the art to make and use the invention. The details and features of the disclosed embodiment[s] are not intended to be limiting, as many variations and modifications will be readily apparent to those of skill in the art.
