the high-pressure and high-temperature refrigerant discharged by the compressor 5 firstly enters the oil separator 1 to separate the refrigerant oil in the refrigerant, and the separated refrigerant oil returns to the gas-liquid separator 7 through the capillary tube 3; the refrigerant passing through the oil separator 1 enters the double-pipe heat exchanger through the four-way valve 26 to be condensed into a high-pressure liquid state, is throttled and cooled by the first expansion valve 14, then enters the server cold plate through the third expansion valve 10 under the action of the fluorine pump 12 to control the flow, absorbs heat generated by the server chip, is subcooled by the economizer 8, then enters the internal machine through the liquid pipe stop valve 4, is throttled by the second expansion valve 33 to become a low-temperature and low-pressure refrigerant, is gasified after absorbing heat in the fluorine cold coil 32, passes through the gas pipe stop valve 30 to the gas-liquid separator 7 to complete gas-liquid separation, and returns to the compressor 5 again to complete the refrigeration cycle.
When the fluorine cold part can not work normally, the electric three-way valve 18 conducts the pipeline flowing to the internal machine at the moment, the electric butterfly valve 19 of the connecting sleeve condenser 22 is closed, the flow entering the fluorine cold coil 32 of the internal machine is adjusted through the adjusting valve 34, and emergency cooling is carried out.
The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the present invention as defined in the accompanying claims.
