[0062] The microstructured ion wind generating unit includes a microstructured high voltage electrode 1 and a microstructured ground electrode 2 .

[0063] When the microstructured ion wind cooling device 4 is working, the microstructured high-voltage electrode 1 is powered by a high-voltage power supply, and the microstructured grounding electrode 2 is grounded. A strong electric field will be generated in the area between the microstructured high-voltage electrode 1 and the microstructured grounding electrode 2 . Under the action of a strong ele...

no. 2 Embodiment approach

[0075] figure 2 It is a perspective view schematically showing the microstructure type ionic wind heat sink 104 according to the second embodiment of the present disclosure.

[0076] The only difference between the microstructured ionic wind heat sink 104 and the microstructured ionic wind heat sink 4 of the first embodiment lies in the shape of the microstructured high voltage electrodes. Specifically, as follows.

[0077] The microstructured high voltage electrode 101 is configured in a shape in which the distance from the microstructured ground electrode 2 varies. For example, the planar shape of the microstructure high-voltage electrode 101 near the downstream side of the ion wind is zigzag, so the electrode spacing of the microstructure ion wind generating unit changes along the width direction (y direction).

[0078] In addition, the size and number of the sawtooth structures of the microstructure high voltage electrode 101 can be properly adjusted according to heat d...

no. 3 Embodiment approach

[0082] image 3 It is a perspective view schematically showing the microstructure type ionic wind heat sink 204 according to the third embodiment of the present disclosure.

[0083] The only difference between the microstructured ionic wind heat sink 204 and the microstructured ionic wind heat sink 4 of the first embodiment lies in the shape of the microstructured high voltage electrode and the microstructured ground electrode. Specifically, as follows.

[0084] The plane shapes of the microstructure high voltage electrode 201 and the microstructure ground electrode 202 are arched. In addition, the width of these electrodes in the radial direction can either remain the same or vary along the circumferential direction.

[0085] In addition, the width of the microstructure high voltage electrode 201 and the microstructure ground electrode 202 in the radial direction and the circumferential angle of the electrodes can be properly adjusted according to the size of the space and ...

Description

technical field [0001] The invention relates to the technical field of heat dissipation of electronic equipment, in particular to an ion wind heat dissipation device and a method thereof. Background technique [0002] With the development of technology, the working capacity of electronic equipment has been continuously improved, which has led to an increase in heat production. However, the miniaturization of equipment has greatly increased the power density of electronic equipment, but the cooling area has been severely reduced. Performance and service life have an important impact, therefore, electronic cooling technology has become an important factor restricting the development of electronic equipment. [0003] The traditional heat dissipation method is mainly a heat sink that combines a fan and a fin heat sink. The motor rotates to drive the fan to drive the air to exchange heat with the fins to achieve the effect of heat dissipation. However, this type of mechanical he...
