Problems solved by technology

[0009] Disadvantageously, the known cooling units are unfavorable with regard to weight and production costs (input of material and working time) and are therefore uneconomical not only for their manufacture but also for their operation in a motor vehicle

Embodiment Construction

[0041] The same reference numbers in the figures indicate the same or similar elements.

[0042] Figures 1 to 7 An exemplary embodiment of an assembly of three electronic power modules to be cooled of a motor vehicle drive and a cooling assembly according to the invention is shown in different illustrations and construction stages.

[0043] figure 1 The overall assembly is shown, the construction of which can be explained more easily with the aid of the exploded and sectional views of the remaining figures. Accordingly, the illustrated embodiments should be described with reference to all figures collectively. Reference to the individual figures means a particularly good visibility of the very details that are discussed in the specifically mentioned figure.

[0044] The illustrated assembly includes a back box 10 . The base box is shaped like a basin with a basin bottom or base box bottom 101 and a basin edge or base box edge 102 . Two openings are arranged in the basin ...

Abstract

The invention relates to a cooling assembly for an electronic component of a motor vehicle and a method of manufacturing the same, in particular to a cooling assembly comprising: a base box with an inlet opening and an outlet opening, the base box being divided into an inlet longitudinal chamber containing an inlet opening and an outlet longitudinal chamber containing an outlet opening, which are fluidically separated from each other and respectively extend over the majority of the length of the base box; a cover plate, fixed on the edge of the base box in a fluid-tight and material-fit manner and being provided with an inflow opening in fluid contact with the inlet longitudinal chamber and an outflow opening in fluid contact with the outlet longitudinal chamber; the frame plate being connected with the covering plate in a fluid-tight manner, penetrating through the frame opening and surrounding a flow opening pair consisting of an inflow opening and an outflow opening of the covering plate; and a contact plate which covers the frame opening and is fixed on the frame plate in a fluid-tight manner, wherein the electronic component to be cooled is fixed or can be fixed on the upper side of the contact plate facing away from the frame opening.

Description

technical field [0001] The invention relates to a cooling assembly for electronic components of a motor vehicle, said cooling assembly comprising: [0002] - a base box with an inlet opening and an outlet opening, the base box being divided into two fluidly separated longitudinal chambers extending respectively over most of the length of the base box, i.e. into an inlet longitudinal chamber and an outlet longitudinal chamber, wherein the inlet opening is arranged in the inlet longitudinal chamber and the outlet opening is arranged in the outlet longitudinal chamber; [0003] - a cover sheet fastened in a fluid-tight material fit on the edge of the basin, said cover sheet having at least one inflow opening in fluid contact with the inlet longitudinal chamber and at least one outflow opening in fluid contact with the outlet longitudinal chamber open mouth [0004] - a frame sheet connected fluid-tightly and preferably materially to the cover sheet, the frame sheet passing thro...
