Embodiment Construction

[0037] The examples described below constitute preferred embodiments of the invention.

[0038] figure 1 A capacitor assembly 10 is shown comprising a capacitor 24 , a first terminal 11 , a second terminal 15 , a cooling device 30 and a housing 27 . The first terminal 11 and the second terminal 15 are respectively connected to one electrode of the capacitor. The first terminal 11 and the second terminal 15 are arranged on a section 14 in a manner of overlapping and extending up and down, wherein an insulating device is further provided between the two terminals 11 and 15 . The insulating device is optionally constructed in multiple layers. The first and second terminals 11 and 15 respectively lead out of the housing 27 in a first edge 28 of the housing 27 . A cooling device 30 , such as a liquid cooler, is arranged above the opening of the casing 27 .

[0039] The first terminal 11 has a first heat absorbing member 12 . The first heat absorbing component 12 is made of a U...

Abstract

The invention relates to a capacitor assembly (10) comprising a capacitor (24), a first terminal (11), a cooling device (30) and a housing (27) which contains the capacitor (24), wherein, the first terminal (11) comprises a first heat absorbing part (12) and a first heat dissipating part (13), the first terminal (11) dissipating heat from a first side (25) of the capacitor (24) to the cooling device (30) via the first heat absorbing part (12) and the first heat dissipating part (13); and wherein the first side (25) of the capacitor (24) faces away from the cooling device (30).

Description

technical field [0001] The invention relates to a capacitor assembly according to the preamble of claim 1 , a system according to the preamble of claim 15 and a vehicle according to the preamble of claim 16 . Background technique [0002] Capacitors with capacitor windings wound on metallized plastic film must have insulating properties. The disadvantage of electrically insulating or plastic foils is that the heat generated in the capacitor is difficult to dissipate, especially if the capacitor has a housing that prevents the heat from being dissipated. Therefore, there is a possibility that the temperature inside the capacitor becomes extremely high, for example, 100° C. or higher, during operation of the capacitor. But should not exceed the determined temperature, otherwise the capacitor will be damaged. [0003] In order to dissipate the heat generated in the capacitor well, it is known from the prior art to bring the capacitor winding into contact with a heat-conductin...
