Heat exchanger assembly and method for operating a heat exchanger assembly

Abstract

A heat exchanger assembly (1) is disclosed. The heat exchanger assembly comprises at least one passive cooling circuit (100), the passive cooling circuit comprising an evaporator (110) connectable toa device (50) to be cooled for conducting heat from the device (50) to be cooled to the cooling fluid within the evaporator (110), thereby evaporating the cooling fluid, and a condenser (120) interconnected with the evaporator (110) for receiving the evaporated cooling fluid from the evaporator (110), releasing heat from the cooling fluid to an environment of the condenser (120), thereby condensing the cooling fluid, and for returning the condensed cooling fluid to the evaporator; and an active partial circuit (200) comprising a compressor (250) and an auxiliary condenser (220), the active partial circuit (200) being activatable and deactivatable and being connected to the passive cooling circuit for receiving, in an activated state of the active partial circuit (200), the cooling fluid from the evaporator (110), for compressing the received cooling fluid by the compressor (250), for releasing heat, by the auxiliary condenser (220), from the compressed cooling fluid to an environment of the auxiliary condenser (220), and for returning the condensed cooling fluid to the evaporator (110). Furthermore, the passive cooling circuit (100) is a base-to-air type thermosiphon or an air- to-air type thermosiphon.

Description

technical field [0001] The present disclosure generally relates to heat exchanger assemblies. Certain embodiments relate to a power electronics component comprising at least one power electronics component and a heat exchanger assembly at least as disclosed herein. Additional embodiments involve the use of heat exchanger assemblies to cool electrical components. Furthermore, the present disclosure relates to methods for operating heat exchanger assemblies. Background technique [0002] In cooling applications, in particular for cooling electrical components, such as power electronic components, heat exchangers are commonly employed. A heat exchanger constitutes a cooling device for removing heat dissipated from a component to be cooled (that is, a process in which heat is transferred from position A (the component to be cooled) to position B (the destination of the removed heat)) at least partly. In particular, the destination of the removed heat involves heat discharge ...

Problems solved by technology

Thermosiphons consume less energy than active refrigeration systems using e.g. compressors and / or pumps, but they are only capable of cooling under more limited environmental conditions
