Cooling device for cooling electronic and/or electric element in targeted manner

Abstract

The invention relates to a cooling device for cooling an electronic and / or electric element, particularly a power semiconductor which is configured on a circuit board. The device is provided with the components of at least one cooling member which is provided with projected heat radiating members which are configured on the surface of the cooling member, wherein the cooling member is thermally coupled with the electronic and / or electric element; at least one cooling medium distributing member which is used for spatially distributing cooling medium to hot spots which are defined by the cooling member in a targeted manner; a cooling device inner chamber which is surrounded by the cooling member and a cooling member tank that can be connected with the cooling member, wherein the cooling device inner chamber at least comprises the projected heat radiating member of the cooling member and the cooling medium distributing member; at least one inlet for conveying the cooling medium into the cooling device inner chamber; and at least one outlet for discharging the cooling medium out of the cooling device inner chamber. Furthermore the cooling device is applied in a converter, and particularly the converter of an electric vehicle or hybrid electric vehicle.

Description

technical field [0001] The invention relates to a cooling device for cooling electronic and / or electrical components, in particular power semiconductors arranged on a circuit board, having at least one cooling body with protruding heat sinks arranged on the surface of the cooling body components, wherein the cooling body is provided for thermal coupling with electronic and / or electrical components. Background technique [0002] Electronic and / or electrical components, as they are used, for example, in industrial converters or in converters for electric or hybrid vehicles, are usually designed for high Electric continuous power and peak power. During operation, these electronic and / or electrical components cause in most cases non-negligible electrical losses, which are mostly converted into loss heat. This heat loss impairs the functionality and lifetime of the electronic and / or electrical components, so efficient heat dissipation is required, that is to say cost-effective ...
