Heat exchanger

Abstract

Heat exchanger (1) having a housing (9), having a first fluid port (6, 7) and having 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.

AI Technical Summary

Benefits of technology

This patent describes a heat exchanger that is made up of plastic and metal parts. The use of plastics reduces the weight of the heat exchanger compared to all-metal construction, while still maintaining good thermal conductivity. The design also ensures a smooth flow of fluid through the exchanger, preventing the formation of flow build-up points that could cause temperature increases. The overall result is a more efficient and lightweight heat exchanger.

Problems solved by technology

In the case of all of the energy stores mentioned, an intense generation of heat occurs during operation, in particular during fast charging and discharging of the energy stores.

Temperatures of approximately 50° C. and higher may however damage the energy stores and significantly reduce the service life thereof.

Likewise, excessively low temperatures cause lasting damage to the energy stores.

A disadvantage of the solutions according to the prior art is in particular that the heat exchangers are composed entirely from aluminum.

Furthermore, the production of heat exchangers from aluminum is energy-intensive and expensive.
