The existing spray heat dissipation technology is generally designed on the premise that the heat generating surface of the electronic component is horizontal and the spray direction is directed downward toward the heat generating surface, and the working liquid can be sprayed downward by gravity onto the heat radiating surface close to the heat generating surface. However, when the electronic component is not horizontal in the state of use, the working liquid to be sprayed is affected by gravity, and the liquid may be concentrated in the lower half of the heat dissipating surface or not in the dissipating surface, resulting in uneven or poor heat dissipation. In addition, when the electronic component is located in a small space, it will be difficult to arrange a device for realizing the spray heat dissipation technology on the heat generating surface thereof.

Referring to FIGS. 2 and 4, the first shell portion 315 of the housing 31 defines a vapor outlet 313 that communicates with the evaporation chamber 311. The second housing portion 316 defines a coolant inlet that communicates with the liquid supply chamber 312 for the inflow of working fluid. 314. Further, the first shell portion 315 of the casing 31 of the present embodiment has a microstructure adjacent to the inner surface of the joint end portion 22, thereby contributing to evaporation of the liquid layer into a vapor, thereby improving the effect of absorbing heat energy by phase change. Referring to Figures 4 and 5, the orifice sheet 32 has a thickness of between 20 and 300 microns (μm) and has a plurality of micropores 320 7 M437482 arranged in a matrix or in a staggered arrangement.

The diameter of the liquid inlet end 321 is larger than the diameter of the liquid discharge end 322 and the orifice is tapered. Referring to FIG. 1 ' FIG. 2 and FIG. 4 , the vapor transmission tube 4 of the present embodiment is made of a material compatible with a working liquid such as a polymer material or stainless steel, and the heat dissipation block therein has a microstructure, and the area of the heat dissipation block is The increase increases the condensation efficiency, giving the vapor a chance to condense into a liquid in the vapor transfer tube 4. The coolant delivery module 5 includes a coolant delivery tube 51, a pump 52 for actuating the working fluid, and a control valve 53 for controlling the flow of the working fluid. The pump 52 can be piezoelectric film, gear or electromagnetic and is compatible with the working fluid; it is worth noting that if the pump 52 is a controllable flow, the control valve 53 can be omitted. The driving force and vapor pressure of the rakes 52 allow vapor or condensed liquid (collectively referred to as fluid) to enter the condenser 6. The condenser 6 includes a hollow storage tank body 61 and a plurality of hollow Korean sheets 62 connected thereto.

And improve the condensation efficiency. When the fluid enters the condensation chamber 602' from the fluid inlet 601, the heat exchange is rapidly performed to release latent heat, condense into a liquid, and cool down to a coolant. The bottom surface of the storage tank body 61 may be slightly inclined (not shown), the coolant outlet 603 is located at a lower portion of the bottom surface of the storage tank body 61, and the fluid inlet 6〇1 position is higher than the coolant outlet 603.
