Abstract

A multi-jet hole gas-liquid two-phase atomization nozzle, comprising a nozzle cap, a nozzle body nested in the nozzle cap, and a gas injection pipe body nested in the nozzle body, wherein the nozzle cap includes an upper cap and a lower cap, and the upper cap is provided with There are a number of injection holes, and the nozzle body is located at the liquid inlet and has a number of liquid inlet holes. The inner wall of the upper cap and the upper wall of the nozzle body form a mixing chamber. The throat cavity surrounded by the wall is communicated with the liquid inlet hole, and the gas injection pipe body is communicated with the mixing chamber. Compared with the prior art, the present invention can realize spraying with multiple spray holes, large coverage area, short droplet breaking distance and high atomization degree with a single spray head, which reduces the complexity of the spray cooling system and largely reduces spray cooling The volume and weight of the system save costs; in addition, the present invention also has a larger spray range, and the water droplets are broken faster and more violently, so that 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...
