Embodiment Construction

[0009] Such as figure 1 As shown, the present invention includes: a micropump 1 , an evaporator 2 , a gas-liquid separator 3 , a condenser 4 , a fan 5 and a three-way valve 6 . The micropump 1 is connected to the liquid inlet of the evaporator 2 through a pipeline, and the outlet of the evaporator 2 is connected to the inlet of the gas-liquid separator 3; the gas-liquid separator 3 has two outlets, and the separated liquid is obtained from the lower outlet. Connected to the inlet A of the three-way valve 6, the separated gaseous condensate flows into the condenser 2 from the outlet at the upper end, the outlet of the condenser 2 is connected to the inlet B of the three-way valve 6, and the outlet C of the three-way valve 6 is connected through a pipeline To the micropump 1, the fan is secured by clips directly above the condenser. The positional relationship of the components along the direction of gravity is as follows: the gas-liquid separator 3 and the condenser 4 are loca...

Abstract

This invention relates to a computer heat dissipation liquid recycling cooling system, which comprises the micro pump, evaporator, gas and liquid separator, condenser, fan and one three-way valve, wherein, the micro pump is connected to the evaporator liquid-in hole; the exit of the evaporator is connected to the gas and liquid separator entrance hole; the separator has two exits and the liquid exit is connected to the three-way valve entrance A and the gas condenser dose flows into the condenser from the upper exit; the exit of the condenser is connected to the three-way entrance B and the exit C of three-way valve is connected to the micro pump through pipes; the fan is fixed above the condenser through clamper.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a liquid circulation refrigeration system for computer cooling. For refrigeration technology. Background technique [0002] With the improvement of computer integration and the increase of system energy, especially the increase of CPU energy. The thermal management of computer systems is facing increasing challenges. According to the forecast of the "International Semiconductor Guide" magazine, the maximum heat dissipation of a single chip board will reach 170w in 2008; at the same time, in order to improve the reliability and life cycle of electronic equipment, the maximum allowable contact temperature will be controlled below 85 degrees. Due to the limitations of the thermophysical properties of the working fluid itself, it is difficult for passive cooling technology to achieve this. So using active cooling methods may be an effective solution, one of which is to use a refrigeration...
