Abstract

The invention relates to a dual fluid nozzle atomizing and cooling closed system for a high-power solid laser. In the system, an open pore on the gas exhaust pipe of a compressor is connected with the gas phase inlet of a heat exchanger through a second control valve; the gas phase outlet of the heat exchanger is connected with a dual fluid nozzle chamber; the gas exhaust pipe of the compressor is connected with the input end of a condenser; the output end of the condenser is connected with the input end of a liquid accumulator; the output end of the liquid accumulator is connected with the liquid chamber of the dual fluid nozzle through a first control valve; the nozzle of the dual fluid nozzle stretches into a heat sink; the heat sink is connected with the gas-liquid two-phase inlet of the heat exchanger through a gas exhaust pipeline and a liquid discharge pipeline; and the superheated steam outlet of the heat exchanger is connected with a gas suction pipe of the compressor. The closed cooling system realizes organic combination of a refrigerating system and an atomizing system; gas is input into the gas exhaust pipe of the compressor, so that the defects of introducing a second fluid from outside are overcome; an air pump is saved and the system is simplified; the nozzle replaces a throttle device; and the system can meet the requirement of lower temperature of hot faces.

Description

technical field [0001] The invention relates to a double-fluid nozzle atomization cooling closed system for high-power solid-state lasers, which is especially suitable for the fields of refrigeration and electronic device cooling. Background technique [0002] Diode-pumped solid-state lasers (DPLs) have attracted great interest due to their high efficiency, high beam quality, compact structure, and long lifetime. In recent years, with the successful development of high-power diode lasers, the development of DPL has been promoted and its application in military, industrial, medical, scientific research and other fields. As the power of solid-state lasers increases, the heat load generated by the device becomes larger and the heat dissipation density becomes higher and higher. Therefore, how to eliminate the heat transformed by power dissipation in a timely manner and solve the problem of heat dissipation and cooling is a must for the development of high-power solid-state lase...
