Description
Technical Field
The invention relates to the technical field of electronic device heat dissipation, in particular to a compact multi-nozzle cooling device.
Background
Currently, on-board electronics such as radar, laser, etc. are evolving at a high speed toward miniaturization and integration. The average heat flux of some high-power electronic devices reaches 500W/cm 2, and the heat flux of local hot spots is even not lower than 1000W/cm 2. Temperature plays a critical role in the stability and reliability of electronic devices. Too high an operating temperature may limit the performance of the electronic device. Therefore, heat dissipation has become an important issue in restricting the long-term stable development of electronic devices.
Spray cooling is one of advanced cooling technologies for solving the heat dissipation problem of high-power electronic devices, and has the advantages of good heat transfer performance, low temperature gradient, less consumption of working media and the like. The spray cooling is that the working fluid is atomized into liquid drops through a high-pressure nozzle and exchanges heat with the surface of a high-temperature heat source in a mode of evaporation, convection and the like, so that the aim of heat dissipation is achieved. In the practical application process, the cooling device is developed towards compact and miniaturized while meeting the heat dissipation of electronic devices. In a cooling device, the use of multiple nozzles for cooling a heat source surface of a larger area has a greater advantage than a single nozzle. However, when working fluid flows through the multiple nozzles from the liquid inlet, uneven flow distribution may occur. In addition, if working fluid passing through the multiple nozzles cannot be discharged in time when cooling the surface of the heat source, a stagnation area is easily formed on the surface of the heat source, so that the problem of uneven temperature on the surface of the heat source can be caused.

The lower baffle 101c is provided with a lower baffle drain port 101c-1, and the lower baffle drain ports 101c-1 are provided with four equal distances.
The heights of the upper baffle plate 101b and the lower baffle plate 101c are equal, and the widths of the upper baffle liquid discharge port 101b-1 and the lower baffle liquid discharge port 101c-1 are equal.
The upper baffle 101b and the lower baffle 101c divide the static pressure cavity 101e into three flow channels a, b and c, and the arrangement mode is as shown in fig. 4, so that the flow rate and the flow velocity of the working fluid flowing out of the liquid outlet 101d are the same, and the working fluid is water or cooling liquid as required.

If the pressure is insufficient, the auxiliary pressurization by the water pump may facilitate the variation of the nozzle assembly 200.
The device changes the water pressure and simultaneously ensures that the nozzle assembly 200 changes synchronously to perform heat exchange better, thereby ensuring the normal operation of the device.
