Embodiment Construction

[0040] As mentioned in the background technology section, electronic products in the prior art mainly use natural heat dissipation to dissipate heat, but the heat dissipation efficiency of this heat dissipation method is low, resulting in low reliability of electronic products that use this heat dissipation method to dissipate heat. The service life is shorter.

[0041] In view of this, an embodiment of the present invention provides an electronic product, including:

[0042] A casing, the casing is provided with ventilation holes;

[0043] A PCB board located in the housing, the PCB board is provided with a positive pole and a negative pole of a power supply;

[0044] A fan located between the PCB board and the housing, the projection of the fan on the PCB board overlaps with the projection of the ventilation hole on the PCB board;

[0045] A switch bar located between the fan and the housing and slidably connected to the housing, the switch bar includes: a first state that...

Abstract

An electronic product, comprising: a housing (1), the housing (1) being provided with ventilation holes (11); a PCB board (2) located in the housing (1), the PCB board (2) The positive pole (21) and the negative pole (22) of the power supply are arranged on it; the fan (3) between the PCB board (2) and the housing (1), the fan (3) on the PCB board (2) The projection overlaps with the projection of the ventilation hole (11) on the PCB (2); the switch bar is located between the fan (3) and the casing (1) and is slidably connected to the casing (1) (4), the switch bar (4) includes: a first state of not completely covering the ventilation hole (11) and a second state of completely covering the ventilation hole (11); wherein, the switch bar (4 ) includes a conductive area, and when the switch bar (4) is placed in the first state, the conductive area is electrically connected to the positive pole (21) and the negative pole (22) of the power supply on the PCB board (2), giving the The fan (3) provides a first drive signal, and the fan (3) starts running. The electronic product has high heat dissipation efficiency, so that its reliability is good and its service life is long.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to an electronic product. Background technique [0002] With the continuous improvement of the performance of electronic products such as wireless network cards and data cards, the heat consumption of their products has also increased significantly. The heat dissipation method of such electronic products in the prior art mainly utilizes natural heat dissipation, that is, the natural flow of air in the external environment exchanges heat with the air inside the electronic product, so as to achieve the purpose of heat dissipation. However, the heat dissipation efficiency of this heat dissipation method is low, resulting in low reliability and short service life of electronic products that use this heat dissipation method to dissipate heat. Contents of the invention [0003] In order to solve the above-mentioned technical problems, an embodiment of the present invention pro...
