Description

High-efficient heat radiation structure of electron cigarette PCBA Technical Field The utility model relates to the technical field of heat dissipation, in particular to a high-efficiency heat dissipation structure of an electronic cigarette PCBA. Background The electronic cigarette is an electronic product imitating cigarette, the tobacco tar containing nicotine and other components is changed into steam by heating and atomizing and the like for users to inhale, the PCBA board inside the electronic cigarette is a printed circuit board assembly, and is formed by welding and assembling a circuit board, electronic elements and the like, is a core component of the electronic cigarette for realizing functions of power supply, atomizing control and the like, the electronic components on the PCBA board can generate a large amount of heat in the operation process, and only dissipate heat in a natural heat dissipation mode in the use process, so that the PCBA board is damaged due to overhigh temperature for a long time, and further optimization requirements exist on the heat dissipation aspect. Disclosure of utility model The utility model aims to solve the technical problem of providing an efficient heat dissipation structure of an electronic cigarette PCBA to solve the problem that the heat dissipation of a PCBA board is to be improved. In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a high-efficient heat radiation structure of electron cigarette PCBA, includes PCBA board, still includes: The cooling assembly comprises a shell arranged above the PCBA plate, openings are formed in the bottom and the side face of the shell, an L-shaped pipe is fixed at the opening of the side face of the shell, the upper opening of the L-shaped pipe is connected with an air inlet of the electronic cigarette shell, a plurality of guide plates are fixed on the inner wall of the shell, and the guide plates are used for guiding air sucked from the L-shaped pipe to the surface of the PCBA plate. Preferably, the bottom of casing is fixed with the spliced pole, and the bottom of spliced pole passes through the screw fixation pole at the top of PCBA board. Preferably, the heights of the guide plates gradually increase, and the height of the guide plates far away from the L-shaped pipe is larger than that of the guide plates close to the L-shaped pipe.
