Embodiment Construction

[0030] Such as figure 1 The electrical device 100 depicted in includes a heat sink 2 comprising an internal volume delimited by at least two opposing faces 20a, 20b. In the example depicted, a part of the heat sink 2 called the main part 2a may comprise cooling channels 21 configured to receive a cooling fluid. The other part of the heat sink, called auxiliary part 2b, does not contain cooling channels. The auxiliary part 2 b is cooled precisely by heat conduction from the auxiliary part 2 b to the main part 2 a , wherein the heat is dissipated by a cooling fluid flowing in the cooling channel 21 . In other words, the auxiliary part 2b forms a protrusion of material from the main part 2a. By not providing cooling channels in the auxiliary part 2b, its size and the final size of the electrical device 100 are thus limited. The heat sink 2 may have a substantially rectangular shape. However, the auxiliary part 2b could receive cooling channels which would increase its size bu...

Abstract

The invention relates to an electrical apparatus including a heat sink and a bus bar. The heat sink includes an internal volume delimited by at least two opposing faces, and the bus bar abuts against the two opposing faces of the heat sink in a manner cooled by the heat sink.

Description

technical field [0001] The present invention relates to electrical equipment, in particular to electrical equipment for electric or hybrid vehicles comprising busbars cooled by the two faces of the cooling fins, and more precisely to electrical systems such as those connected to electrification systems cooling of the inverter of the engine). Background technique [0002] It is known to use electrical equipment with bus bars. Precisely, such busbars are intended to convey electrical energy from an interface (external interface to be precise) of an electrical device to internal components of the electrical device. For example, bus bars connect terminals of electrical equipment with capacitors of the electrical equipment. A bus bar generally comprises a lead frame made of metal to be precise, held by a body made of electrically insulating material, plastic to be precise. Electronic components may be received on the bus bars to allow filtering of signals flowing in the leadfr...
