Definitions

the invention relates to a heat sink, in particular for the walls of the upper furnace an electric arc furnace or a shaft furnace, the hot furnace atmosphere is exposed, with a on the hot side forming the heat transfer Layer of copper or copper alloy and on the cold side of trough-shaped Cooling channels formed by the coolant and are guided on the Cold side connected to a coolant supply and a coolant outlet are.
Such heatsinks replace the formerly common ff lining from around the mid - 1970s and form wall elements in box shape with coolant baffles in the box Inside and with different forms of slag holders on the hot side.
box-shaped wall elements were replaced by tubular structures.
the tubes arranged vertically in a so-called tube-to-tube construction, however after a short time was generally replaced by a horizontal arrangement.
This design had the advantage of mechanical stability, but also the disadvantages high pressure drops and the need to install slag holders, the have only a limited life and often the starting point for cracks in the pipes.
Such exposed to the hot furnace atmosphere wall elements have only one limited lifespan and are often affected by damage.
the damage can be divided into cracks on the tube surface, damage by scrap (when charging an electric arc furnace) Damage caused by arcing and spark erosion, damage from oxygen and damage to back plates.
the initially described heat sink is known from DE 100 00 987 A1.
the heat sink is made of a forged or rolled ingot of copper manufactured and the cooling channels are formed by trough-shaped rolled products.
Raw block uneconomical in view of its material costs.
the resistant increasing power requirements lead to increasing heat loads of the Cold plates inside by tensile stresses and on the outside wall by Compressive stresses are claimed.
the material-specific Stress limits When exceeding the material-specific Stress limits, the material is plastically deformed, whereby cracks and in severe cases damage the heat sink.
From DE 29 07 511 C2 is also a full copper or a copper alloy machined heat sink with vertical blind holes by mechanical Deep drilling made.
the material costs and processing are corresponding uneconomical.
the invention is based on the object, a claimable design with to create economically inexpensive to produce components, while copper or to save copper alloy and achieve a long service life.
the stated object is achieved in that one of the hot side assigned, in its thickness determinable plate or frame plate made of copper or Copper alloy, closed by a permanently elastic seal, wherein a plurality of trough-shaped, arranged parallel to each other Longitudinal profiles either in the thickness of the plate or the frame plate or in the permanently elastic sealing are provided as cooling channels and that the Plate or frame plate with one of iron or steel materials, the cold side forming cover plate is tightly connected.
the variety of trough-shaped longitudinal profiles causes a planar more uniform dissipation of heat to the cooling medium. The load capacity of the heat sink is higher overall.
the elastic seal consists of thermally conductive Plastic, heat-resistant rubber or a metal membrane.
the Sealing limited according to the invention the cooling channel or more cooling channels and is thereby cooled by the coolant itself. For this reason, there is one Protection against heat stress, so that such elastic materials permanently can be used.
the ratio of the wall thicknesses of the cover plate to the plate of copper or copper alloy is equal to or less than 1.
a relatively thin cover plate or a corresponding claimable cover plate arises from the fact that the cover plate by means of outwardly projecting Ribs is reinforced.
cover plate with the plate or the frame plate made of copper or a copper alloy welded to the outer circumference are.
the permanent elastic seal is provided by ribs, that of the plate or the frame plate made of copper or a copper alloy, the cooling channels from the Form long profiles.
the seal itself can be stiffened and the Elasticity of the seal is permanently maintained.
the cooling channels in the cover plate and / or the seal can be used as ribs in the Cross section form a triangular shape, a semicircular shape or a trapezoidal shape. in the general are here polygonal or round cross-sectional or cross-sectional mixing forms advantageous.
a further embodiment be made such that either the cavity within the triangular shape, the semicircular shape or the Trapezoidal form the cooling channels or each lying between two ribs Outbuildings.
the heat sink 1 is shown vertically. He can also be horizontal or be installed at an angle.
On the hot side 2 (right) is the Layer 3 of copper or copper alloy.
3a is a variety of individual Cooling channels 4 formed with smaller flow cross sections for a coolant 5, which usually consists of water. In a variety of cooling channels are these are formed from long profiles 4a (FIGS. 2A-5B).
the long sections 4a are located on the cold side 6 (left), on the also a coolant supply line 7 and a coolant discharge 8 are connected, which lead the coolant 5 in the circuit.
the plate 9 or the frame plate 9a carries the heat to the individual cooling channels 4, which consist of the plurality of trough-shaped, parallel juxtaposed long sections 4a.
a cooling channel 4 either a cavity 19 (FIG. 3A) of the long profile 4a or an auxiliary space 20 formed by two adjacent long profiles 4a can be used as flow channels.
the plate 9 or the frame plate 9a are by a permanently elastic seal 10 closed, wherein on the cold side 6 one of iron or steel materials 11 existing cover plate 12 fixed to the plate 9 or the frame plate 9a, for example, on the outer circumference 9b by welding or as drawn by means Screws 12a are connected.
the ratio of the wall thicknesses of the cover plate 12th to the plate 9 or frame plate 9a made of copper or copper alloy is the same or less than 1.0.
the permanently elastic seal 10 is made of thermally conductive plastic, heat-resistant rubber or a metal membrane.
the cover plate 12 (Fig. 1) by means of outward be reinforced protruding ribs 13.
On the hot side 2 are usually Provided (unspecified) grooves, if necessary, after completion of assembly the application of refractory ramming or spraying masses when using the heat sink 1 in a shaft furnace or when using the heat sink 1 for an electric arc furnace to catch the inevitable melting spatter.
Fig. 2A except for the layer 3, copper or copper alloy is on the hot side 2, the plate 9 and the frame plate 9a can be seen, and the permanently elastic Seal 10, which in a first embodiment, a plurality of cooling channels 15 forms (FIG. 2B), each between two cross-sectional triangular shapes 16 arise.
the permanently elastic seal 10 is approximately as a "mat" in one piece executed and is simply inserted into the frame plate 9a and by means of the cover plate 12 closed. In the event that the cooling channels 15 in the plate 9 or the frame plate 9a are provided, the permanently elastic seal 10th also be smooth and flat.
FIG. 3A shows a second alternative embodiment of the heat sink 1, being on the hot side 2 within the layer 3 of copper or copper alloy in Form of the frame plate 9 a recess is provided, in turn as Matt the permanently elastic seal 10 with a variety of long products 4a inserted and by means of the cover plate 12 made of iron or steel materials 11th and screws 12 is attached.
This embodiment sees hollow longitudinal profiles 4a before, so that between each two longitudinal profiles 4a coolant through an adjoining room 20 forward and back flow through the cavity 19 of the long sections 4a can.
longitudinal profiles 4a are located in the recess of the frame plate 9a with a semicircular shape 17 in cross section and form between two long profiles 4a a cooling channel 15.
the long sections 4a form connecting webs again the permanently elastic sealing as a mat.
the bases are the flow channels 15 can be seen.
FIGS. 5A and 5B A fourth alternative is shown in FIGS. 5A and 5B: the long profiles 4a have Trapezoidal shape 18 in cross section, again between each two long profiles 4a a cooling channel 15 for the flow and the interior of the trapezoidal mold 18 for the Return of the coolant (or vice versa) can be connected.
Heatsink 1 which takes up little space and easy to install.
