Definitions

  • the invention relates to a plate-shaped heat exchanger, the one from the edge welded together Sheets exist, at least in the rest are partially spaced apart, and with at least an inlet and an outlet.
  • Such heat exchangers are for example from DE 19524277 known. They are usually liquid refrigerants flows through, while the outer surfaces with a Cooling liquid are sprinkled or the entire heat exchanger immersed in a liquid to be cooled. While the refrigerant is in a closed system circulates and flows through the inside of the heat exchanger plate, is the outside contacting the heat exchanger plate Liquid in an open system that is for many applications is not suitable. Furthermore there is a desire to heat transfer between the two Improve liquids. Heat exchangers where circulate both liquids in closed systems, are, for example, tubular heat exchangers. These are however, it requires a lot of material, is complicated and expensive Manufacturing.
  • An object of the present invention is a simple and inexpensive heat exchanger for heat exchange between two closed systems create.
  • This object is achieved in that at least three sheets to form at least two separate heat exchanger chambers at the edges are welded and that each of these heat exchanger chambers has its own inlet and outlet.
  • this heat exchanger Because to manufacture this heat exchanger essentially only three or four simple sheets welded together must be, there is a very inexpensive production a closed heat exchanger for two circuits with little material.
  • the heat transfer between the two heat exchanger chambers is very good and it only a very small volume of refrigerant is required, so that the need for refrigerant is also relatively low is. Due to the plate-shaped design of the heat exchanger very little space is required, so that many such heat exchangers in a composite very can be arranged compactly.
  • the sheets welded together at the edges are additional over a variety of welds with each other connected and otherwise have to form the heat exchanger chambers extending in opposite directions Bulges on. These welds are more advantageous Point-like manner and in particular evenly distributed over the plate shape, so that too a mechanically very stable and resistant construction is achieved.
  • the welds can too as welding lines to form flow channels be formed between the inlet and outlet, so that a defined flow in the heat exchanger is achieved by which can also optimize the heat transfer.
  • the heat exchanger consists of three sheets, of which the middle sheet is flat and the two outer Sheet metal have bulges facing outwards, whereby between the middle plate and one of the two outer plates one of the two heat exchanger chambers is formed.
  • the heat exchange is excellent and takes place over the middle sheet.
  • Heat exchanger plates is essentially just that half the volume of refrigerant needed.
  • the heat exchanger consists of four sheets, with between an inner heat exchanger chamber for the two inner plates and between each of the inner sheets and one of the two outer sheets, another outer heat exchanger chamber is formed. This can be done again an increase in heat transfer can be achieved, in particular then when the refrigerant through the inner Heat exchanger chamber flows. The heat exchange can then done on all sides, since the inner heat exchanger chamber from two external heat exchanger chambers is completely enclosed.
  • the inner and outer sheets each have bulges on the opposite in the same places extend outwards so that common welding spots for All sheets are connected to each other.
  • the two outer ones, delimited by the outer sheets Heat exchanger chambers can be connected in series or in parallel and effectively form one Heat exchanger chamber.
  • the inlet and outlet the inner heat exchanger chamber on the edge Welding must be arranged, and the inlet and outlet each of the two outer heat exchanger chambers is on a bulge arranged.
  • the heat exchanger plate according to the invention is expedient designed as a component of a cooling system, part of the heat exchanger chambers with a first refrigerant circuit having a refrigerator and the other part of the heat exchanger chambers with a second one having a consumer to be cooled Coolant circuit is connected. This will through the plate-shaped heat exchanger a closed one Cooling system formed. Depending on the required heat transfer or depending on the required heat exchanger area the size of the heat exchanger can be varied, or he is in series with other similar heat exchangers or connected in parallel to create a compact unit form.
  • the heat exchanger or can advantageously several heat exchangers also in one with a liquid filled cold storage can be arranged.
  • the first embodiment illustrated plate-shaped heat exchanger 10 consists of three identical rectangular sheets 11 - 13, which are placed on top of each other and welded together at the edge.
  • the circumferential weld seam 14 along the edge of the heat exchanger 10 is, for example, by plasma welding, Laser welding or TIG welding are formed.
  • the sheets 11 - 13 over a variety of welding spots 15 connected together, evenly along the sheets 11-13 are arranged.
  • the one heat exchanger chamber 23 for the primary circuit has an upper inlet pipe section 18 and a lower drain pipe section 19.
  • Die another heat exchanger chamber 24 for the secondary circuit however, has a lower inlet pipe section 20 and one upper drain pipe section 21. This is an opposite Flow of the two liquid media through the Heat exchanger 10 guaranteed.
  • FIGS. 3 and 4 are used to form a plate-shaped Heat exchanger 25 four sheets 26 - 29 placed one on top of the other and with each other according to the first embodiment welded.
  • This will form after pressurization a middle heat exchanger chamber 30, which is delimited by the two inner sheets 27, 28, and two on either side of the middle Heat exchanger chamber 30 adjoining outer heat exchanger chambers 31, 32.
  • the inlet pipe section 33 and outlet pipe section 34 for the middle heat exchanger chamber 30 are arranged in the area of the upper weld seam 14, that is, this weld 14 is from above pierced, and the pipe sections 33, 34 are welded.
  • the weld lines 16 to form the flow channels 17 have a different from the first embodiment Arrangement and differ in that that at the lower end of the total flow channel formed another flow channel piece 38 again vertically is led upwards so that the inlet and outlet pipe sections 33 - 37 each arranged on the upper corner areas can be.
  • the arrangement of the welding lines 16 or the flow channel 17 can of course vary, so that the arrangement according to FIG. 3 also for example with a heat exchanger according to the first embodiment and the arrangement according to FIG. 1 also by a heat exchanger according to the second embodiment can be realized. 3 are for simplification the welding points 15 are not shown. In simpler ones Comments can also be made on the welding points 15 or the welding lines 16 are dispensed with.
  • the two outer Heat exchanger chambers 31, 32 also in parallel or in Be connected in series and are then ready for connection the secondary circuit of a cooling system is provided, while the middle heat exchanger chamber 30 to Connection to the primary circuit is provided so that the middle heat exchanger chamber through which refrigerant flows 30 heat transfer to all sides Secondary circuit allowed.
  • the plates 10, 25 or sheets 11-13, 26-29 are made made of stainless steel, but in principle also other materials or alloys are possible. This depends on the particular one Working temperature and the refrigerants used Coolants.
  • the inlet and outlet pipe sections 18, 19 of a heat exchanger chamber 23 are connected to one as the primary circuit trained refrigerant circuit 39 connected in a circulation pump 40 and a refrigeration machine 41 switched are.
  • the other two inlet and outlet pipe sections 20, 21 of the other heat exchanger chamber 24 to a coolant circuit designed as a secondary circuit 42 connected, also in the circulation pump 43 and a consumer 44 to be cooled are.
  • the heat exchanger 10 is in a liquid-filled Cold storage 45 arranged, for example can be designed as a water-filled container.
  • Heat exchanger 10 In the cold store 45 there are three further corresponding lines Heat exchanger 10 shown. This is supposed to be made clear that several heat exchangers are required 10 can be connected in series or in parallel can, on the one hand, to increase the heat transfer, and to on the other hand, in the present case, the refrigeration in Increase cold storage 45.
  • a refrigerant circulates in the refrigerant circuit 39, for example R 717 (NH 3 ), R 407, R 22, R 290 (propane).
  • a coolant for example glycol, salt water, water or water with other chemical additives, circulates in the coolant circuit 42, that is to say in the secondary circuit.
  • the heat transfer from the primary circuit to the secondary circuit takes place via the heat exchanger (s) 10.
  • the cold store 45 has thermal insulation 46. If the cooling capacity of the primary refrigerant circuit 39 is higher than the demand of the consumer 44, cold is stored in the cold store 45, that is to say the liquid contained therein cools down, in the case of water until ice forms. If the consumer 44 needs more cooling, this stored cold can then be used.
  • chiller 41 it is also possible, for example, to operate the chiller 41 only at low-cost night-time electricity and thereby form ice in the cold store 45, and to use this stored cold during the day for the consumer 44, the chiller 41 being switched off, partly switched off or operating at a lower power can be.
