## Abstract

Embodiments of the present disclosure are directed to a cold plate assembly for an electrical cabinet, including: a main body part, a sealing part, and a mounting part. The main body part is provided with a channel for the circulation of a liquid cooling medium and an accommodation groove located on a first upper surface of the main body part. The sealing part is disposed in the accommodation groove and the mounting part is located above the sealing part. A lower surface of the mounting part faces the main body part, and a second upper surface of the mounting part is configured to mount an electronic device to be cooled.

## Claims

### Claim 1

A cold plate assembly for an electrical cabinet, comprising:
a main body part comprising a channel and an accommodation groove, wherein the channel is configured to circulate a liquid cooling medium, and wherein the accommodation groove is located on a first upper surface of the main body part;
a sealing part disposed in the accommodation groove; and
a mounting part positioned above the sealing part, wherein a lower surface of the mounting part faces the main body part, and a second upper surface of the mounting part is configured to mount an electronic device to be cooled by the liquid cooling medium.

### Claim 2 (depends on 1)

The cold plate assembly of claim 1, wherein the main body part comprises at least one plate-like component.

### Claim 3 (depends on 1)

The cold plate assembly of claim 1, wherein the mounting part comprises at least one plate-like component.

### Claim 4 (depends on 1)

The cold plate assembly of claim 1, wherein the sealing part comprises at least one sealing ring.

### Claim 5 (depends on 1)

The cold plate assembly of claim 1, wherein the main body part is made of a material containing aluminum, or plastic, or both.

### Claim 6 (depends on 1)

The cold plate assembly of claim 1, wherein a flow channel is formed in the first upper surface of the main body part, and the flow channel communicates with the channel through a liquid outlet and a liquid inlet.

### Claim 7 (depends on 1)

The cold plate assembly of claim 1, wherein the mounting part is made of copper.
