A power electronics system includes a multipart housing having three housing elements of cuboid basic structure to define a central element with inlet and outlet ports for a cooling liquid, an upper and lower cover elements which are arranged on opposite connection surfaces of the central element. A plurality of power electronics switching devices is accommodated in the housing, and a condenser device having condenser connection elements is arranged in the central element of the housing&#x3e; Further provided is a liquid cooling system having at least one first upper cooling chamber between the central element and the upper cover element, and at least two first and second lower cooling chambers between the central element and the lower cover element. The upper and lower cooling chambers are configured for circulation of the cooling liquid entering through the inlet port and exiting through the outlet port of the housing.

Power electronics system with liquid cooling system

A housing for retaining an electronic component, including a lid and a lower part made of synthetic material, wherein the lid is joined in a force-fit manner to the lower part by clamping geometry, and in order to affix the electronic component in position, the lid applies a specified force (F) to the electronic component after being joined to the lower part due to its design. Here, the lid is designed in such a manner that the force (F) applied lies within a specified force range (B), and that the clamping geometry comprises a groove on the lower part and a ridge on the lid which grips into the groove, wherein a clamp web on the lower part or on the lid is arranged in such a manner that the lid is removably clamped to the lower part after being joined to the lower part with a force (F) which acts parallel to the clamping force (KF).
