Embodiment Construction

[0049] figure 1 A perspective view of the heat exchanger 1 is shown. The heat exchanger 1 essentially comprises a housing 9 which is formed from a housing lower part 2 and a housing upper part 3 . The heat exchanger 1 has a first fluid connection 6 and a second fluid connection 7 . The two fluid connections 6 , 7 can be used selectively as fluid inlets or fluid outlets.

[0050] The housing upper part 3 extends substantially planarly. The housing bottom part 2 is essentially formed by a channel-shaped bottom region with upstanding edge regions. The dimensions of the housing upper part 3 are such that it closes the housing lower part 2 with an exact fit. A fluid-tight connection can thus be produced between housing upper part 3 and housing lower part 2 . The inner volume formed between housing bottom part 2 and housing top part 3 corresponds to the volume of housing 9 through which fluid can flow.

[0051] The housing lower part 2 has a plurality of flow-guiding elements ...

Abstract

The invention relates to a heat exchanger (1) having a housing (9), a first fluid port (6, 7) and a second fluid port (7, 6), wherein the housing (9) is in fluid communication with a fluid source via the first fluid port (6, 7) and the second fluid port (7, 6) and can be traversed by a flow of a fluid, characterized in that the housing (9) is of multi-part design and is formed by a housing upper part (3) and a trough-like housing lower part (2), wherein the housing lower part (2) has a base region (7) and an at least partially encircling turned-up edge region (6), wherein the housing upper part (3) or the housing lower part (2) is formed from a plastic and the respective other housing part (3, 2) is formed from a plastic, a metallic material or a fiber composite material.

Description

technical field [0001] The invention relates to a heat exchanger having a housing, a first fluid connection and a second fluid connection, wherein the housing is in fluid communication with a fluid source via the first fluid connection and the second fluid connection and through which a fluid can flow. Background technique [0002] An accumulator is used in an electric vehicle to drive an electric motor. The energy storage used here often consists of rechargeable batteries based on lithium-ion technology or nickel-metal hydride rechargeable batteries. As an alternative to this, high-performance capacitors, so-called supercapacitors, can also be used. [0003] In all mentioned energy stores, a great deal of heat is generated during operation, especially during rapid charging and discharging of the energy store. [0004] But temperatures of around 50° C. and higher damage the accumulators and greatly reduce their service life. Likewise, too low a temperature continuously da...
