Problems solved by technology

[0002] The existing cooling device has a simple structure and a single function. Dust will enter the inside of the optocoupler while dissipating heat, which will cause damage to the cooling device of the optocoupler, which is not conducive to the long-term use of the cooling device of the optocoupler. It will cause a certain degree of damage to the photocoupler, and the entire device needs to be removed for maintenance, which is time-consuming and labor-intensive

Embodiment

[0020] Embodiment: When the device is in operation, the air inside the airbag 6 will expand, and the airbag 6 will gradually approach the sidewalls at both ends of the placement groove 5, which will drive the first elastic rod 8 connected to the airbag 6 to move downward, so that The fixed block 20 is removed from the heat dissipation hole 14, so that the heat dissipation hole 14 will discharge the heat in the device under the action of the micro-electromechanical fan 7. After the heat dissipation is completed, the air bag 7 will return to its original state, and the elastic device will also return to its original position. When the cover block 17 can be locked on the fixed rod 19, the third elastic rod 16 is not moved, and then the elastic device is not moved, so that the fixed block 20 can be fixed in the heat dissipation hole 14 when not working, so that it will not Dust falls and affects the normal use and service life of the device, and the third elastic rod 16 will shrink...

Abstract

The invention discloses a heat dissipation device for a photoelectric coupler. The heat dissipation device for the photoelectric coupler comprises a main body; a rotating shaft is glidingly connectedto the side wall at one end of the main body; a movable plate is rotatably connected to the side wall at the other end of the rotating shaft; a heat dissipation hole is arranged on the upper end of the main body; a connection block is in screwed connection on the inner wall at the bottom of the main body; a placement groove is in riveted connection on the side wall at the upper end of the connection block; an air bag is fixedly connected to the inner wall at the bottom of the placement groove; the other end of the air bag is fixedly connected to a first elastic rod; a first spring is fixedly connected to the side wall at the bottom of the first elastic rod; a first placement block is in screwed connection on the side wall at one end of the first elastic rod; a second elastic rod is in screwed connection at the lower end of the first placement block; a second spring is fixedly connected to the side wall at the bottom of the second elastic rod; and a second placement block is in screwedconnection on the side wall at one end of the second elastic rod. The device disclosed by the invention is convenient to maintain; furthermore, falling of dust can be effectively prevented in a heat dissipation process; and thus, the service life of the device can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of heat dissipation devices, in particular to a heat dissipation device for an optocoupler. Background technique [0002] The existing cooling device has a simple structure and a single function. Dust will enter the inside of the optocoupler while dissipating heat, which will cause damage to the cooling device of the optocoupler, which is not conducive to the long-term use of the cooling device of the optocoupler. It will cause a certain degree of damage to the photocoupler, and the entire device needs to be removed for maintenance, which is time-consuming and labor-intensive. Contents of the invention [0003] The object of the present invention is to propose a heat dissipation device for an optocoupler in order to solve the shortcomings in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A heat dissipation device for ...
