Airborne liquid cooling system

Abstract

The invention relates to the field of airborne environmental control, in particular to an airborne liquid cooling system. The airborne liquid cooling system comprises: a refrigerant circulation subsystem, which comprises a first refrigerant circulation subsystem and a second refrigerant circulation subsystem for independent refrigeration circulation; the secondary refrigerant circulation subsystem comprises a liquid storage tank, a booster pump and a heat exchanger which are sequentially connected to the inlet end and the outlet end of the load to form a secondary refrigerant circulation loop; each refrigerant circulation subsystem comprises a compressor, a condenser, a liquid storage device and a throttling element which are sequentially connected to form a loop. An outlet of the throttling element is connected with a refrigerant channel inlet of the heat exchanger, and a refrigerant channel outlet is connected with an inlet of the compressor. The booster pumps comprise the first booster pump and the second booster pump which are arranged in parallel. The airborne liquid cooling system can meet the heat dissipation requirement of airborne equipment, can guarantee the working continuity of the airborne electronic equipment, guarantees the flight safety, prolongs the service life of the airborne electronic system, and improves the reliability of the airborne electronic system.

Description

technical field [0001] The invention relates to the field of airborne environmental control, in particular to an airborne liquid cooling system. Background technique [0002] With the development of modern aircraft avionics technology and the continuous improvement of power device manufacturing technology for airborne electronic equipment, the assembly density and power density of airborne electronic equipment continue to increase. The cooling system must solve the heat dissipation problem of high-power equipment and meet the airborne The reliability of the equipment must also meet the temperature consistency requirements of each component of the equipment; therefore, feasible cooling methods and excellent cooling effects have become more and more important supports for airborne electronic equipment to have high reliability indicators. With the development of technologies such as carrier-based aircraft and unmanned aerial vehicles, more airborne electronic equipment needs to...
