## Abstract

A cooling system includes at least one coolant-conducting heat sink configured to cool a battery. The cooling system also includes further coolant-conducting components including at least one conduit configured to feed coolant to the at least one heat sink and at least one conduit configured to carry coolant away from the at least one heat sink. At least some of the further coolant-conducting components are at least partially surrounded by at least one sheathing element, such that a closed volume space is formed between the at least one sheathing element and the at least some of the further coolant-conducting components.

## Claims

### Claim 1

A cooling system, comprising:
at least one coolant-conducting heat sink configured to cool a battery; and
further coolant-conducting components, including:
at least one feed conduit configured to feed coolant to the at least one heat sink; and
at least one carry conduit, separate from said feed conduit, configured to carry coolant away from the at least one heat sink,
wherein the further coolant-conducting components are at least partially surrounded by a sheathing element, such that a closed volume space is formed between the sheathing element and the further coolant-conducting components, and
wherein the sheathing element is a plastic film, and
wherein the sheathing element has a closing mechanism configured to be opened and closed in a fluid-tight manner to enable arrangement of the sheathing element to surround the further coolant-conducting components.

### Claim 2 (depends on 1)

The cooling system according to claim 1, wherein the sheathing element has a thermally insulating configuration.

### Claim 3 (depends on 1)

The cooling system according to claim 1, wherein the sheathing element has at least one drain opening configured to drain off liquid within the volume space.

### Claim 4 (depends on 1)

The cooling system according to claim 1, wherein the sheathing element has a mechanism configured to detect moisture within the volume space.

### Claim 5 (depends on 1)

The cooling system according to claim 1, wherein the sheathing element has a gastight configuration, such that the sheathing element is configured to be filled with gas, wherein the gas-filled sheathing element is spaced apart from the further coolant-conducting components.

### Claim 6 (depends on 1)

The cooling system according to claim 1, wherein the sheathing element has an at least partially transparent configuration, such that the further coolant-conducting components which are surrounded by the sheathing element are at least partially visible.

### Claim 7 (depends on 1)

The cooling system according to claim 1, wherein the at least one heat sink is configured to cool the battery configured as an energy source to drive one of a hybrid vehicle, a plug-in vehicle, and an electric vehicle.
