Abstract

The invention relates to a closed spray cooling experiment system suitable for various cooling madia, belongs to the field of high-efficiency heat exchange and aims to solve the problem of the lack ofan experiment table which is simple to operate and multiparameter-adjustable in the research field of spray cooling technology. The system mainly comprises a gas-liquid separator (1), a compressor (2), a refrigerant liquid storage tank (3), a first stop valve (4), a pre-cooler (5), a refrigerant condenser (6), a drying filter (7), a bypass regulating valve (8), a first flow regulating valve (9),a second stop valve (10), a flowmeter (11), a spray chamber (12), an auxiliary electric heater (13), a third stop valve (14), a second flow regulating valve (15), a filter (16), a pump (17), a non-refrigerant liquid storage tank (18), a fourth stop valve (19) and a non-refrigerant condenser (20). The system has multiple advantages that spray cooling experiments using various liquids and various refrigerants as media can be conducted, the cooling media can be recycled, multiple parameters can be adjusted, use is convenient and the like.

Description

technical field [0001] The invention relates to a closed spray cooling experiment system applicable to various cooling media, which belongs to the field of high-efficiency heat exchange. Background technique [0002] Laser weapons are standard equipment for next-generation fighters. Such weapons will generate megawatts of heat within seconds of firing, resulting in extremely high thermal loads and extremely high heat fluxes on their surfaces, which can reach hundreds or even thousands of W / cm 2 . High heat flux will damage the laser medium, and the heating problem of laser weapons has become a bottleneck restricting the further improvement of its output power. How to timely transfer the high heat flux formed by energy dissipation after launch is the key technology that must be overcome in the development of airborne high-power directed energy weapons . [0003] Spray cooling is a new type of cooling method that decomposes the cooling medium into countless discrete small d...
