Energy recovery gas-liquid two-phase circulating cooling system

Abstract

The invention discloses an energy recovery gas-liquid two-phase circulating cooling system which comprises a first compressor, a gas flow controller, an atomizing pump, a cooling area, a temperature sensor, a fin tube heat exchanger, a second expansion machine, an electric generator, a storage battery, a gas-liquid separator, an air pump, a liquid delivery pump and a controller. A micropore in thesurface of the impeller outlet of the atomizing pump atomizes low temperature gas-liquid two-phase flow into a low temperature high-pressure gas-liquid mixture, and the low temperature high-pressuregas-liquid mixture can be in direct contact with the cooling area for heat dissipation; the fin tube heat exchanger absorbs the heat of high-temperature high-pressure gas-steam mixture for power generation, and the generated electric energy is stored in storage battery to be used by power generation equipment in the cooling system; after heat dissipation and pressure drop of the high-temperature high-pressure gas-steam mixture in the fin tube heat exchanger, the high-temperature high-pressure gas-steam mixture enters the gas-liquid separator; after gas-liquid separation, deionized water entersthe liquid delivery pump, the air flows into the external environment, and the operation condition of the entire system is adjusted by the controller.

Problems solved by technology

Traditional air cooling technology, due to the low density of the cooling gas, the density is usually 1-2kg / m at normal temperature and pressure 3 , the specific heat is about 1kJ / kg, so its heat capacity is limited, the heat conduction efficiency is extremely poor, and the fan will generate noise during operation

The same volume of water and cooling gas absorb the same amount of heat, and the cooling gas temperature rises about 4,000 times that of water. However, in many cases, the cooling area cannot be in direct contact with water. It is difficult to operate water cooling through cooling pipes, and the structure of the water cooling system is relatively Complicated and inefficient in recycling heat resources
