Abstract

Disclosed is a multi-spray-hole gas-liquid two-phase atomization nozzle. The multi-spray-hole gas-liquid two-phase atomization nozzle comprises a nozzle cap, a nozzle body arranged in the nozzle cap in a nested manner, and a gas injection pipe body arranged in the nozzle body in a nested manner; the nozzle cap comprises an upper cap and a lower cap, and the upper cap is provided with a plurality of spray holes; the end, at the liquid inlet position, of the nozzle body is provided with a plurality of liquid inlet holes; and the inner wall surface of the upper cap and the upper wall surface of the nozzle body define a mixing cavity, the spray holes communicate with the liquid inlet holes after sequentially passing through the mixing cavity and a throat cavity defined by the inner wall surface of the nozzle cap and the outer wall surface of the nozzle body, and the gas injection pipe body communicates with the mixing cavity. Compared with the prior art, the multi-spray-hole gas-liquid two-phase atomization nozzle has the advantages that the single nozzle can realize multi-spray-hole spraying with a large coverage area, a short water droplet breaking distance and a high atomization degree, the complexity of a spray cooling system is reduced, the size and weight of the spray cooling system are reduced to a great extent, and the cost is saved; and besides, the multi-spray-hole gas-liquid two-phase atomization nozzle has a larger spraying range, water droplets break more rapidly and violently, and a better atomization effect can be obtained.

Description

technical field [0001] The invention belongs to the technical field of spray cooling technology, in particular to a multi-spray hole gas-liquid two-phase atomization nozzle. Background technique [0002] With the continuous advancement of science and technology, microelectronics technology has developed rapidly, and electronic components have shown a trend of continuous improvement in performance and integration, and increasing power density. Big. The thermal control system of electronic equipment is directly related to the stability, reliability and working life of the equipment. To achieve efficient heat dissipation in a limited space has become a bottleneck in the development of high-performance and highly integrated electronic equipment. As a new and efficient thermal control technology, spray cooling has many advantages compared with traditional forced air cooling and liquid cooling, including strong heat dissipation, fast temperature control response, and small contac...
