Abstract

The present invention provides a heat exchanger (100) for removing heat energy from a heat generator (200), comprising at least one conduit (110) for a working fluid, which is arranged in an upright position of at least 45°, each conduit having an exterior wall (112) and at least one interior wall (114) for forming at least one evaporator channel (120) and at least one condenser channel (130) within the conduit (110). Furthermore, the heat exchanger (100) comprises a first heat transfer element (150; 183) for transferring heat into the evaporator channel (120) and a second heat transfer element (180) for transferring heat out of the condenser channel (130).

Description

technical field

[0001] The present invention generally relates to a heat exchanger. In particular, the invention relates to a heat exchanger that can be used in power electronics. Background technique

[0002] Low voltage drive systems have a competitive market among global players. This imposes a strict low cost condition on its design. In a typical system, power electronic components such as discrete or integrated (ie module type) semiconductor components, inductors, resistors, capacitors and copper bus bars are packed in close proximity. PCB panels and control electronics are also present on all designs. During operation, these elements emit variable amounts of heat. Additionally, these components can tolerate variable levels of temperature. The ambient conditions of the surround drive system also vary in terms of air temperature, humidity, dust and chemical content. In addition to the electrical performance of the system, the thermal management and integration conc...
