Problems solved by technology

[0004] However, the forced convection cooling device has the problems of noise generated when the fan is running and the service life of the fan; the natural convection cooling device has the problems of large volume and single upward flow field limitation, so it is still criticized and difficult to solve.

Embodiment Construction

[0034] Please refer to shown in Fig. 1, the first kind of embodiment of ion wind cooling device of the present invention includes:

[0035] A metal body 10 electrically connected to a voltage source, which is an upright sheet-shaped body, and the metal body 10 is provided with several protruding jagged sharp structures 11 on the same side;

[0036] The metal grounding body 20 is arranged at the corresponding position of the sharp structure 11 of the metal body 10 at a predetermined distance and forms a grounded metal grounding body 20. Sheet-shaped body, the hole 21 can be circular or other shapes;

[0037] The insulating frame 30 maintains the relative distance between the metal body 10 and the metal grounding body 20 .

[0038] When the metal body 10 is supplied with a voltage, a corona phenomenon will be generated around the sharp structure 11 under a strong electric field, so that the nearby air is ionized, and the ionized air ions repel the same kind of charge on the sha...

Abstract

An ion wind heat dissipating device includes a metal body electrically connected with a voltage source and provided with a plurality of sharp structures as well as a metal grounding body arranged at corresponding positions sharp structures of the metal body at a preset distance and grounded. The metal body is a sheet-shaped body, and the sharp structures are in saw-teeth shape and formed on the same side of the sheet-shaped body. By applying voltage on the sharp structures of the metal body, corona phenomenon is generated between the sharp structures and the grounded metal grounding body to perform ionization on air close to the sharp structures, and the ionized air generates incompatibility with the same charges on the sharp structures and then emits ions to the metal grounding body to convert the metal grounding body into an ion receiver and further to form electric wind or balled ion wind which drives air flow to flow from the metal body to the metal grounding body, thereby generating hat dissipating effect.

Description

technical field [0001] The invention relates to an ion wind cooling device. Background technique [0002] When the general electrical appliance is used, it will be accompanied by the generation of heat, which is obtained from the conversion of electric energy. However, most electrical appliances and electronic components do not have good adaptability to high heat, that is, high temperature will cause electrical appliances to The performance of electrical appliances or electronic components is reduced or damaged. Therefore, in order to prevent the electrical appliances or electronic components from accumulating excessive heat energy during operation and causing the temperature to rise, heat sinks are often used to dissipate heat. [0003] It is more common to see electronic components or electrical appliances that use heat sinks, such as the chips of electronic components in computers. The heat sinks used generally have a metal heat conductor that is in direct contact with th...
