Abstract

A manufacturing method of a cold plate structure comprises a plate body and a pipe. The plate body has a first side and a second side. A groove is formed on the second side. The pipe is embedded in the groove correspondingly. The pipe is filled with a gas. By means of the design of the present invention, the oxidation on the inner wall of the pipe can be avoided. Consequently, the operating efficiency is significantly increased and the manufacturing cost is reduced.

Claims

1. A manufacturing method of a cold plate structure, comprising the steps of:

providing a pipe and using vacuum equipment to vacuum the pipe;

providing gas filling equipment to fill the pipe with a gas;

providing a sealing device to seal the filled pipe; and

placing the pipe in a mold and providing a liquid metal cast in the mold and cooling down to form a cold plate structure.

2. The manufacturing method of the cold plate structure according to claim 1, wherein the gas is selected from the group consisting of hydrogen, nitrogen, and any other gas.

3. The manufacturing method of the cold plate structure according to claim 1, further comprising an adapter which has an inlet and an outlet, wherein the inlet and the outlet are individually connected to two ends of the pipe.
