Refrigeration Principle of Liquid Cooling System

 

The general structure of the liquid cooling system: the outdoor side includes the cooling tower, the primary side pipe network, and the primary side coolant; the indoor side includes the CDU, liquid cooling cabinets, ICT equipment, the secondary side pipe network, and the secondary side coolant.
According to the cooling principle, cold plate type, immersion type and spray type are the three main deployment methods of liquid cooling at present. Among them, immersion and spray liquid cooling are contact liquid cooling, and the cooling liquid is in direct contact with the heating device.

(1) Immersion liquid cooling: Immersion liquid cooling immerses all the heating elements of IT equipment in the cooling liquid to achieve heat dissipation. According to whether the working fluid undergoes phase change, it is divided into single-phase liquid cooling and phase change liquid cooling. The cooling liquid after absorbing heat is cooled or condensed by means of air cooling or water cooling.

(2) Spray-type liquid cooling: Spray-type liquid cooling relies on pump pressure or gravity drive, and precisely sprays cooling liquid from top to bottom to the IT equipment circuit board according to the demand of heating elements, and the heat-absorbing cooling liquid is air-cooled or water-cooled Equal circulation cooling.

(3) Cold plate liquid cooling: The cold plate liquid cooling is a non-contact liquid cooling, and the cooling liquid does not directly contact the heating device. The cold plate type liquid cooling passes the cooling liquid to the cold plate that is in contact with the heating element of the IT equipment through the flow channel to export the heat, and the cooling liquid after absorbing heat is circulated and cooled by air cooling or water cooling.
