Cold plate heat sink and liquid cooling module

Abstract

A cold plate radiator includes a base and at least one set of cold plate modules. The cold plate modules are fixedly mounted on the base via elastic clamping members. Each cold plate module includes a base plate and a cover plate. The base plate has a receiving cavity for containing coolant, and the cover plate covers the opening of the receiving cavity. A through hole is formed on the end face of the base, communicating with the receiving cavity. A corrugated pipe is provided between two adjacent cold plate modules, with both ends of the corrugated pipe connected to the inner walls of two through holes, allowing coolant to flow between the multiple cold plate modules through the corrugated pipe. This novel cold plate radiator offers excellent heat dissipation while being adaptable to different application scenarios.

Claims

1. A cold plate heat sink, characterized in that it comprises a base and at least one set of cold plate modules, the cold plate modules being fixedly mounted on the base via elastic clamping members, each cold plate module comprising a base and a cover plate, the base having a receiving cavity for containing coolant, and the cover plate covering the opening of the receiving cavity, the end face of the base having a through hole communicating with the receiving cavity; a corrugated pipe is provided between two adjacent cold plate modules, the two ends of the corrugated pipe being respectively connected to the inner walls of the two through holes, the coolant flowing between the multiple cold plate modules through the corrugated pipe.

2. The cold plate heat sink as described in claim 1, wherein, The cold plate module comprises multiple units. The first cold plate module has a liquid inlet pipe on its end face, which is opposite to the through hole and communicates with the receiving cavity. Coolant enters the receiving cavity through the liquid inlet pipe. The last cold plate module has a liquid outlet pipe on its end face, which is opposite to the through hole and communicates with the receiving cavity. Coolant in the receiving cavity flows out through the liquid outlet pipe.

3. The cold plate heat sink as described in claim 1, wherein, The base has blind holes on its end face, and a connector is provided between two adjacent cold plate modules. The connector is an elastic deformation structure, and its two ends are respectively connected to the inner walls of the two blind holes.

4. The cold plate heat sink as described in claim 3, wherein, The connector is a hollow tubular structure.

5. The cold plate heat sink as claimed in claim 1, wherein, Both the base and the corrugated pipe are made of copper.

6. The cold plate heat sink as claimed in claim 1, wherein, The base is made of stainless steel.

7. The cold plate heat sink as claimed in claim 1, wherein, The elastic clamping member has two elastic arms, and each of the cover plates has a positioning groove adapted to the elastic arms. The elastic clamping member is detachably clamped on the base. During installation, the elastic arms are received in the positioning grooves and pressed against the cover plate, thereby locking the cold plate module on the base.

8. The cold plate heat sink as described in claim 7, wherein, The elastic clamping member is provided with a barb portion, and the base is provided with a snap-fit ​​port that cooperates with the barb portion. When the elastic clamping member is cooperated with the base, the barb portion passes through the snap-fit ​​port.

9. The cold plate heat sink as claimed in claim 8, wherein, The elastic clamping component is made of annealed stainless steel.

10. A liquid cooling module, characterized in that it is fixedly mounted on a base via an elastic clamping member and comprises: The cold plate module includes a base and a cover plate. The base has a receiving cavity for containing coolant, and the cover plate covers the opening of the receiving cavity. The end face of the base has a through hole that communicates with the receiving cavity. A corrugated pipe is provided between two adjacent cold plate modules. The two ends of the corrugated pipe are respectively connected to the inner walls of the two through holes. The coolant flows between the multiple cold plate modules through the corrugated pipe.
