Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, the present embodiment provides a fast air-cooling heat dissipation PCB, which includes a PCB body 1, a heat conduction plate 2, and a fan 3, wherein the front surface of the PCB body 1 is provided with a plurality of electronic components 11, the back surface of the PCB body 1 is connected to the front surface of the heat conduction plate 2, the center of the back surface of the heat conduction plate 2 is provided with a circular groove 222, the fan 3 is installed in the circular groove 222, the back surface of the heat conduction plate 2 is further provided with a plurality of circular grooves 223 and a plurality of linear grooves 221, each circular groove 223 is concentric with the circular groove 222, one end of each linear groove 221 is communicated with the circular groove 222, the other end of each linear groove 221 is aligned with the edge of the heat conduction plate 2, and the intersection of each circular groove 223.
Like 1 and fig. 2, the temperature risees when electronic components 11 during operation on the PCB body 1, leads to PCB body 1 temperature to rise, and the heat conduction of PCB body 1 to heat-conducting plate 2, the last fan 3 of heat-conducting plate 2 rotates, and the wind of production takes away the heat fast. It should be noted that the fan 3 needs to be connected to an external power supply device, such as a battery, and the power supply device of the fan 3 is not described herein in detail because it is the prior art.
As shown in fig. 2, when the fan 3 rotates, the wind can flow in the linear grooves 221, and the linear grooves 221 are connected with the circular grooves 223 in a cross-shaped manner, so that the wind can flow in the circular grooves 223, and the arrangement of the linear grooves 221 and the circular grooves 223 greatly increases the heat dissipation area of the heat conduction plate 2 and can improve the heat dissipation efficiency.
As shown in fig. 3, in order to improve the heat conduction efficiency between the PCB body 1 and the heat conduction plate 2, the heat conduction plate 2 includes a heat conduction silicone sheet 21 and an aluminum plate 22, and the heat conduction silicone sheet 21 is located between the aluminum plate 22 and the PCB body 1. The two sides of heat conduction silica gel piece 21 can be without interval with PCB body 1 and aluminum plate 22 contact, utilize heat conduction to aluminum plate 22 of heat conduction silica gel piece 21 with PCB body 1, the fan 3 that sets up on the rethread aluminum plate 22 blows away the heat, improves heat conduction efficiency.
Referring to fig. 1, in order to prevent the fan 3 from being damaged by being touched by other objects during the rotation process, a protective cover 4 is disposed on the fan 3, and the protective cover 4 is connected to an aluminum plate 22.
Adopt above-mentioned each technical scheme, the utility model discloses a set up heat-conducting plate and fan at the back of PCB body, blow away the heat that electronic components on the PCB body gived off fast, realize the normal atmospheric temperature work of PCB body, simple structure.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
