Two-phase liquid cooling system

Abstract

The invention discloses a two-phase liquid cooling system. The two-phase liquid cooling system comprises a condenser, a refrigerant pump and a refrigeration tail end; the condenser is connected with the inlet of the refrigerant pump; at least one branch of the outlet of the refrigerant pump is connected with the condenser by use of the refrigeration tail end; a liquid storage tank for storing the refrigerant is arranged between the condenser and the refrigerant pump; a flow control device is arranged between the outlet of the refrigerant pump and the refrigeration tail end. The cooling system is applied to the fields of power electronics and telecommunications; the adopted refrigerant is Freon, and is good in insulation property and gaseous under normal pressure, and therefore, even though the refrigerant leaks, the potential safety hazard of short circuit can be avoided; as a result, the problems of water leakage short circuit, regular exhaust maintenance and the like due to a water cooling system are solved; meanwhile, due to two-phase heat exchange, the heat exchange coefficient is high and the problem of insufficient heat dissipation density of forced air cooling is solved. The Freon is adopted to realize two-phase heat exchange, and the phase-change gasification latent heat is far higher than that of single-phase heat exchange of traditional water cooling; as a result, under the same heat exchange amount, the flow of the refrigerant needed by two-phase liquid cooling is far smaller than that of the traditional water cooling system.

Description

technical field [0001] The invention belongs to the technical field of telecommunications and power electronics, and relates to a two-phase liquid-cooled cooling system. Background technique [0002] In the field of electric power, the cooling systems used for SVG / SVC, converter valves, converters, frequency converters, etc. are generally air-cooled and water-cooled. Air cooling generally uses forced convection heat exchange through a fan blowing radiator, and its application is relatively limited. First, the noise is high; second, the heat exchange density is too low, and the application scenarios are limited. Water cooling generally uses liquid water to flow in the water-cooled plate to take away the heat of the high-temperature components of the equipment, and then dissipate it to the atmosphere through the external radiator, and form a cycle through the pump. During the application process of the water cooling system, there are many problems such as water leakage, exhau...
