Problems solved by technology

However, this technique uses a pump which increases the size and cost of the cooling system
In addition, in terms of the design of the atomizer, this technology proposes to use a structure similar to that of an inkjet head to generate micro-droplets after heating the fluid, but this design consumes a relatively high power supply
In addition, the spray circulation cooling device disclosed in U.S. Pat. No. 5,687,577 also uses a pump as the source of circulation power, so the cooling system using this technology has a large volume and cost
[0005] To sum up, there is an urgent need for a compact spray cooling cooling device to solve the shortcomings of the existing technology, such as increased volume due to the installation of pumps, increased cost, and high power consumption for spraying.

Abstract

The invention relates to a compact atomization cooling radiator, which comprises liquid groove for storing cooling liquid; atomizing chamber connected to the thermal source; atomizer above the chamber which has piezoelectric plate and porous plate with several ejection holes; the atomizer can atomize the cooling liquid to generate atom in the atomizing chamber to take away thermal energy; and it also has one liquid transmitter for adsorbing the cooling liquid in the groove to the atomizer. The invention also can have condenser and transmission tube, to form a compact sealed atomization cooling radiator.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a compact spray cooling heat dissipation device. Background technique [0002] The calorific value of electronic components increases rapidly with the improvement of semiconductor integration; how to improve the heat dissipation capacity of electronic components to ensure the normal operation of components has become a very important engineering topic. The direct air cooling technology currently widely used can no longer meet the heat dissipation requirements of electronic components with high heat flux, and other solutions must be sought. [0003] Among them, the spray cooling heat dissipation system uses the principle of phase change after the coolant absorbs heat to assist in heat dissipation. Due to the extremely high latent heat of liquid phase change, it is suitable for use in heat dissipation systems with high heat and high heat flux. At present, the spray cooling heat dissip...
