## Abstract

The invention relates to a module housing made of plastic, in particular a thermosetting polymer, with an embedded cooling element and at least one screw sleeve, which has a collar with an exposed mounting surface with which the module housing can be mounted on a support functioning as an external heat sink. The cooling element and the at least one screw sleeve form a monolithic element with which heat can be conducted from the cooling element to the support via at least the mounting surface.

## Claims

### Claim 1

A module housing, comprising:
a cooling element and at least one screw sleeve,
wherein the at least one screw sleeve has a collar with a mounting surface with which the module housing can be mounted on a support and function as an external heat sink,
wherein the cooling element and the at least one screw sleeve form a monolithic element,
wherein the at least one screw sleeve is configured such that heat is conducted from the cooling element to the support via at least the mounting surface, and
wherein the mounting surface is raised in relation to an outer surface of the cooling element, forming a space between the cooling element and the support, such that when the module housing is mounted on the support, only the mounting surface bears on the support.

### Claim 2 (depends on 1)

The module housing according to claim 1, wherein the at least one screw sleeve includes only one screw sleeve.

### Claim 3 (depends on 1)

The module housing according to claim 1, wherein the at least one screw sleeve is completely connected to the cooling element over a height of the cooling element along a cylindrical axis of the at least one screw sleeve, and wherein a cross section of a monolithic connection between the cooling element and the at least one screw sleeve is configured for thermal discharge along the height of the cooling element.

### Claim 4 (depends on 1)

The module housing according to claim 1, wherein the at least one screw sleeve is connected over its width with the cooling element, which corresponds to at least an outer diameter of the at least one screw sleeve, and a cross section of a monolithic connection between the cooling element and the at least one screw sleeve is configured for thermal discharge along a width of the cooling element.

### Claim 5 (depends on 1)

The module housing according to claim 1, wherein the mounting surface is circular.

### Claim 6 (depends on 5)

The module housing according to claim 5, wherein the mounting surface has an outer diameter that is at least twice the size of an inner diameter of the mounting surface.

### Claim 7 (depends on 1)

The module housing according to claim 1, wherein the module housing is made of plastic.

### Claim 8 (depends on 1)

An electrical assembly comprising a module housing according to claim 1.

### Claim 9 (depends on 1)

A motor vehicle that has a control comprising an electrical assembly that has a module housing according to claim 1.

### Claim 10 (depends on 7)

The module housing according to claim 7, wherein the plastic is a thermosetting polymer.
