Liquid cooling system for server main board

Abstract

The present invention provides a liquid cooling system for a server main board. The system comprises a vertically positioned cooling cylinder in which an insulation refrigerant is arranged, a vertically positioned refrigerant recovery vat and a mobile machine arranged between the cooling cylinder and the refrigerant recovery vat; and the server main board is immersed in the insulation refrigerant in the cooling cylinder, and an openable and closeable cover plate capable of allowing the mobile machine to extend in is arranged at the top of each of the cooling cylinder and the refrigerant recovery vat. By adopting the liquid cooling system provided by the present invention, while the server main board is effectively cooled, the maintenance of the server main board is enabled to be more convenient and the insulation refrigerant is effectively recycled; the cooling and maintenance of the server main board are implemented in an environmentally-friendly, energy-saving and high-efficiency manner; the steam of the insulation refrigerant is prevented from leaking and dissipating, and the cooling capability of the cooling system is ensured; the personal safety of system operators is ensured; and the working efficiency of the server main board is improved and the working life of the server main board is prolonged, so that the service life of a computer that applies the server main board is prolonged and the and reliability of the computer that applies the server main board is improved.

Description

technical field [0001] The invention relates to an insulating refrigerant cooling system, in particular to a liquid cooling system for a server motherboard. Background technique [0002] As a mature heat dissipation technology, liquid cooling has been widely used in the field of heat dissipation for personal computers. The application of liquid cooling technology to the computer field is due to the fact that the heat dissipation rate of liquid is much faster than that of air, so the liquid cooling radiator has a good heat dissipation effect, and at the same time, the noise can also be well controlled. Due to various advantages in heat dissipation efficiency and quietness, liquid cooling also appeared shortly after computer air cooling became popular. Today, the gradual popularization of liquid cooling in the computer field is due to the safety and stability of liquid cooling. [0003] At present, most of the insulating refrigerants used in liquid-cooled server motherboards...

Problems solved by technology

However, since water with impurities is a good conductor, the cooling system composed of cooling water is likely to cause the short circuit of the circuit board caused by leakage; and the use of insulating refrigerant to cool the main board of the server, once the sealing effect is poor, the insulating refrigerant vapor Easily leaks and dissipates, resulting in loss of insulating refrigerant and reduced cooling capacity of the liquid cooling system

At the same time, once the server submerged in the cylinder fails and needs to be repaired, the maintenance personnel must open the upper cover and take out the server immersed in the insulating refrigerant.

In this process, the long-term and large-area direct contact between the insulating refrigerant and the atmosphere will not only cause the volatilization and waste of the insulating refrigerant, but also increase the concentration of chemical reagents in the confined space, and reduce the work of the server motherboard.
