Problems solved by technology

like figure 1 As shown, it includes a thermosiphon accumulator 1, a condenser 3 and a high-pressure accumulator 6, and the liquid outlet of the condenser 3 and the liquid inlet of the thermosiphon accumulator 1 are communicated through a condenser liquid outlet pipe 4, The overflow port of the thermosiphon liquid accumulator 1 and the liquid inlet of the high-pressure liquid accumulator 6 communicate through the thermosiphon liquid accumulator overflow pipe 5. The shortcoming of this thermosiphon oil cooling system is that the liquid refrigerant condensed by the condenser It has a certain degree of subcooling, which is offset by the high temperature saturated return air from the thermosiphon oil cooler, which loses the degree of supercooling and causes a waste of energy
[0003] Many technicians try to solve the technical problem of subcooling loss, but they all start from the internal structure of the thermosiphon liquid reservoir 1, which inevitably increases the complexity of the structure of the thermosiphon liquid reservoir 1, and the corresponding Increased complexity of thermosiphon oil cooler process

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a thermosiphon oil cooling system. Background technique [0002] At present, refrigeration systems are generally divided into thermosiphon oil cooling and water cooling. Water cooling is an energy-saving oil cooling method. Its disadvantages are that it consumes water resources, and the heat exchanger is prone to fouling that affects heat transfer. Thermosyphon oil cooling uses the pressure difference formed by the different densities of liquid and gas to circulate, without pumps and other conveying equipment. Compared with water cooling, thermosiphon oil cooling can save water source, and can avoid fouling in the heat exchanger and affect heat transfer, so it is widely used. like figure 1 As shown, it includes a thermosiphon accumulator 1, a condenser 3 and a high-pressure accumulator 6, and the liquid outlet of the condenser 3 and the liquid inlet of the thermosiphon accumulator 1 ar...
