A kind of cold plate and its manufacture and use method

Abstract

Provided in embodiments of the present invention are a cooling plate and methods for the manufacture and use thereof, related to the technical field of phase transition heat dissipation and at least capable of solving the problem in the prior art of, when the internal fluid in a cooling plate using two-phase heat exchange technology flows from top to bottom, gas in the fluid easily causing gas blockage and thereby degrading heat dissipation. The present cooling plate comprises a cooling plate body and a number n of channels in the cooling plate body, of which each of a number m of channels has disposed within it at least one flap-like flexible structure; the flap-like flexible structures comprise a fixed end and a free end, the fixed end being nearer a first opening in the channel in the lengthwise direction of the channel and the free end being nearer a second opening in the channel in the lengthwise direction of the channel when fluid flows from the first opening toward the second opening, the flap-like flexible structure changes shape when exposed to an impulse greater than a preset threshold, which increases the flow cross-section of fluid in the channel past the flap-like flexible element; the size of the impulse is positively correlated with the flow volume of fluid in the channel. Embodiments of the present invention may be used in heat dissipation.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of phase change heat dissipation, and in particular to a cold plate and its manufacturing and usage methods. Background technique [0002] The liquid cooling technology generally refers to inserting multiple cold plates into the communication equipment, and dissipating heat from the communication equipment through the flow of liquid inside the cold plates. Two-phase heat exchange technology refers to the principle that the working fluid changes from liquid to gas to absorb a large amount of latent heat of vaporization and take away a large amount of heat. Compared with the fluid flowing in and out of the traditional cold plate is liquid, the application of two-phase heat exchange technology to the cold plate can make the fluid flowing into the cold plate be liquid, and the fluid flowing in the cold plate is usually a mixture of gas and liquid The fluid flowing out of the cold plate is ...
