Cooling machine with double condensation and double cooling

Abstract

The invention discloses a liquid cooler with double condensation and double heat dissipation. On the basis of a conventional liquid cooler (with dual modes of compressor refrigeration and forced air cooling), a special cycle branch is added to realize a special cycle, forming a double Condensation double heat dissipation structure realizes condensation heat release and forced air cooling function. The special cycle is composed of three kinds of cycles, namely, compressor refrigeration cycle + coolant refrigeration cycle + coolant heat dissipation cycle. Working in this state, it can realize The liquid supply temperature is regulated by dual control of compressor refrigeration and forced air cooling, which can avoid the risk that the forced air cooling mode alone cannot meet the temperature control requirements when the ambient temperature is low and the temperature control range is wide, or the risk that the compressor cooling mode alone may occur Condensation mismatch or insufficient liquid return, etc., so as to enhance the environmental adaptability of the unit.

Description

technical field [0001] The invention relates to the field of liquid coolers, in particular to a liquid cooler with double condensation and double heat dissipation. Background technique [0002] The main purpose of the chiller is to provide the cooling object with a certain temperature, flow and pressure of the circulating refrigerant, that is, the coolant. With the rapid development of some high-power radars, lasers, cabinets, medical and printing equipment in recent years, there are more and more requirements for cooling machines. For example, people pay more and more attention to the performance of products in terms of energy saving, high efficiency, reliability and environmental adaptability. Especially for the cooling machine for important purposes, including the cooling machine for military equipment, in the face of the harsh environment and climate change in the field, how to improve the quality of the product requires more countermeasures. [0003] In order to meet ...

AI Technical Summary

Problems solved by technology

At this time, there will be two deficiencies: ①The liquid return temperature is still higher than the ambient temperature by 10°C to 15°C, and the forced air cooling mode cannot be fully used to reflect energy saving; ②When the compressor refrigeration cycle is 5°C relative to the ambient temperature, it will cause condensation If the temperature is too low, it will cause some negative effects on operation
