Abstract

The invention discloses a spray cooling type cold plate and relates to the technical field of cooling. The spray cooling type cold plate comprises a cold plate shell, a liquid inlet port, a liquid discharge port, a liquid separation chamber, an atomization chamber and an atomization nozzle. The cold plate shell is a hollow shell and is provided with the liquid inlet port and the liquid discharge port, and the inner cavity of the cold plate shell is separated into the liquid separation chamber and the atomization chamber. The liquid separation chamber communicates with the liquid inlet port, and the atomization chamber communicates with the liquid discharge port. The atomization nozzle is installed between the liquid separation chamber and the atomization chamber, an inlet of the atomization nozzle faces the liquid separation chamber, and an outlet faces the atomization chamber and communicates with the liquid separation chamber and the atomization chamber through the atomization nozzle. The spray cooling type cold plate has the advantages that the liquid cooling plate technology and the spray cooling technology are combined, the applicability is high, and the heat dissipation performance is good.

Description

technical field [0001] The invention relates to the technical field of cooling, in particular to a spray cooling cold plate. Background technique [0002] With the rapid development of electronic devices in the direction of miniaturization, miniaturization and integration, their power density and calorific value also increase, and the ensuing heat accumulation and temperature increase negatively affect the reliability and stability of electronic devices. Therefore, achieving efficient heat dissipation in a compact space has become a key bottleneck restricting the development of high-power electronic devices. [0003] Spray cooling is an emerging high heat flux heat dissipation technology. Compared with traditional cooling technologies, it has the advantages of strong heat dissipation, low contact thermal resistance, and small demand for working fluid. According to the existing public information, spray cooling has achieved 1200W / The heat dissipation performance above cm2 h...
