Definitions
- the invention relates to a heat exchanger, in particular a thermoelectric heat pump, for controlling the temperature of a battery, as well as a battery arrangement with such a heat exchanger.
- thermoelectric heat pumps found in automotive engineering in the cooling of various components such. Modern lithium-ion batteries application, which develop considerable heat during operation.
- thermoelectric heat exchangers in the form of heat pumps can also be used in electric motor vehicles as a combined heating and cooling device, for example for tempering the passenger compartment, especially as they have a significantly higher efficiency than conventional electrical resistance heaters.
- the fields of application of thermoelectric heat exchangers in motor vehicles are therefore manifold in nature.
- thermoelectric heat exchangers installed in vehicles are therefore often produced in plate or layered construction, wherein the thermoelectrically active Elements are disposed within a thermally conductive housing and supplied to carry heat with an external electrical supply voltage.
- thermoelectric elements It is an object of the present invention to discover new ways of developing heat exchangers with thermoelectric elements.
- thermoelectrically active element an external electrical supply voltage, so that this - depending on the polarization of said electrical voltage - due to the thermoelectric Effects heat transported from the second cover to the first cover or vice versa.
- thermoelectric element sandwiched in a support frame between two covers allows a realization of the heat exchanger with a small space requirement, in particular along a stacking direction, along which the two covers and the support frame are stacked with the at least one thermoelectric element.
- a plurality of clip-type fasteners are attached to an outer peripheral edge of the heat exchanger formed by the two covers and the support frame along the circumferential direction. By means of these fasteners, the two covers are pressed against each other and each against the support frame. This improves the thermal coupling of the two covers to the support frame and to the at least one thermoelectric element arranged therein.
- the first cover is formed in two layers with a first layer facing the support frame and a second layer facing away from the support frame.
- the at least one fluid channel of the channel structure is formed between the two layers.
- this side is substantially completely flat - ie completely flat except for unevenness with negligible lateral extent - formed. This property of the first cover facilitates the realization of the heat exchanger in flat construction.
- the at least one thermoelectric element is a Peltier element.
- Such Peltier elements are commercially available in large quantities and inexpensively. Thus, in particular when using several Peltier elements considerable cost advantages in the production of the heat exchanger.
- a particularly high heat transfer performance can be achieved in the heat exchanger if at least two thermoelectric elements, preferably a plurality of thermoelectric elements, are arranged adjacent to one another in the passage opening. Said thermoelectric elements are preferably held by means of respective holding elements, in particular in the manner of struts, in the passage opening of the support frame.
- Particularly preferred, because space-saving, is a grid-like arrangement of the thermoelectric elements with at least two raster lines and at least two grid columns.
- a sealing device is arranged between the two covers, which seals the cavity formed by the passage opening of the support frame against the external environment.
- the at least one thermoelectric element can be prevented from damage or destruction by contaminants present in the ambient air.
- the sealing device comprises two sealing rings, which are arranged on opposite sides of the support frame and both enclose the passage opening completely circumferentially. In this way, the desired sealing can be realized on both sides of the support frame cost.
- the heat exchanger when the support frame is formed as a plastic injection molded part, in which at least one electrical conductor for supplying the at least one thermoelectric element with electrical energy from an external electrical energy source is arranged.
- the at least one electrical conductors encapsulated by the plastic of the support frame.
- a separate, electrically insulating sheath of the electrical conductor can be omitted in this way.
- a plurality of such electrical conductors can each be electrically insulated from each other by molding with the plastic of the support frame. This variant allows a simple electrical wiring of existing in the support frame thermoelectric elements with an external electrical power source.
- FIGURE 1 shows in an exploded view an example of a heat exchanger 1 according to the invention, which can be used as a thermoelectric heat pump for a battery arrangement.
- the heat exchanger 1 has a first cover 2 a and a second cover 2 b, which lie opposite one another along a stacking direction S. Sandwiched between the two covers 2a, 2b in the stacking direction S is a support frame 3.
- the support frame 3 includes a through-opening 4, in which a plurality of thermoelectric elements 22 are arranged.
- thermoelectric elements 22 are adjacent to one another with the formation of a grid 16 and are arranged at a distance from one another in the passage opening 4.
- the number of thermoelectric elements 22 can be varied in variants of the example.
- the grid 16 with the six thermoelectric elements comprises two grid lines 25 and three grid columns 26.
- the thermoelectric elements 22 can be held in the passage opening 4 by means of suitable holding elements 24.
- the thermoelectric elements 22 are preferably realized as Peltier elements.
- first cover 2a is a channel structure 5 with a plurality of fluid channels 6 - in Figure 1, the possible course in the first cover 2a is schematically indicated - formed, which is designed to flow through with a fluid.
- a fluid may be a coolant or refrigerant, which serves as a cooling medium for a thermally coupled to the heat exchanger 1 battery.
- Said fluid can enter the channel structure 5 via a fluid inlet 7 arranged laterally on the first cover 2a and again out of the channel structure via a fluid outlet 8 which is likewise arranged laterally on the first cover 2a 5 exit.
- thermoelectric elements 22 for the fluid flowing through the channel structure 5 can be arranged in FIG. This causes improved heat exchange of the fluid with the thermoelectric elements 22.
- the second cover 2b is realized as a cover plate 9, which is formed at least on a side facing away from the support frame 3 side 10 substantially planar. This makes it possible to attach the second cover 2b to the battery housing of a battery unit to be tempered by means of the heat exchanger 1 for the purpose of highly effective thermal coupling.
- a housing wall 1 1 of such a battery housing of the battery to be tempered is indicated in Figure 1 in dashed lines.
- the first cover 2 a may be formed as a cover plate 27.
- One or both covers 2a, 2b may be formed as a stamped or formed sheet metal part.
- a plurality of bracket-like fastening elements 13 may be arranged.
- fastening elements 13 which are shown in the exploded view of Figure 1 on the second cover 2b, the two covers 2a, 2b are pressed against each other and each against the support frame 3.
- the support frame 3 on a frame material, which consists of at least 75% of a plastic.
- a side 17 of the first cover 2 a facing the support frame 3, in particular the first layer, is flat in a surface area of at least 75%.
- the support frame 3 is preferably formed as a plastic injection molded part, in which electrical conductor 23 is arranged for supplying the thermoelectric elements 22 with electrical energy from an external electrical energy source.
- the electrical conductors indicated in the example scenario only roughly schematic, are encapsulated by the plastic of the support frame 3 and therefore do not require a separate, electrically insulating sheathing.
- the first cover 2a is formed in two layers and has one with the support frame 3 facing first layer and a second frame facing away from the support frame 3 (the two layers are not shown in Figure 1 for clarity).
- the channel structure 5 with the fluid channels 6 is preferably formed between the two layers.
