Efficient heat dissipation elastic swing blade type signal isolator

Abstract

The invention discloses an efficient heat dissipation elastic swing blade type signal isolator, and belongs to the field of signal isolators. The efficient heat dissipation elastic swing blade type signal isolator comprises a shell, a plurality of uniformly distributed heat dissipation cavities are formed in the side end of the shell, and a plurality of semi-concentric-square-shaped pipes in one-to-one correspondence with the heat dissipation cavities are arranged in the shell. Through cooperative use of re-striking balls and an actuating connecting rope, under the action of self gravity and motion inertia, the multiple re-striking balls sequentially and circularly fall onto the multiple main elastic pieces to impact the main elastic pieces, the main elastic pieces are triggered to elastically swing up and down, air flow between the heat dissipation cavities and the outside is accelerated, meanwhile, the re-striking balls move in the semi-concentric-square-shaped pipes, the air pressure change in the semi-concentric-square-shaped pipes can be changed, introduction of heat in the shell into the semi-concentric-square-shaped pipes is accelerated, then the heat enters the heat dissipation cavities and exchanges heat with the outside, rapid and effective heat dissipation in the shell is achieved through the dual effects, and the service life of the signal isolator is prolonged.

Description

Technical field [0001] The present invention relates to the field of signal isolators, and more particularly, relates to an efficient cooling of the leaf spring force pendulum signal isolation. Background technique [0002] Signal isolation is a linear optocoupler isolation principle, the input signal switching output. Input, output and operating three isolated power supply, particularly suitable for electrically isolating a device needs equipped with instrumentation, is an important component of industrial control systems. [0003] Signal isolation work will produce heat, resulting in the performance of the electronic components used in the separator decreases, resulting in an output value of the isolator is changed, therefore, on the one hand, the prior art has gradually signal isolation to the low power consumption direction, on the other hand, even with low-power electronic device, which will work when a certain amount of heat, and therefore signal isolation needs to have a g...

AI Technical Summary

Problems solved by technology

[0003] When the signal isolator is working, it will generate heat, which will cause the performance index of the electronic components used in the isolator to decline, and cause the output value of the isolator to change. Therefore, on the one hand, the signal isolator in the prior art has gradually moved towards low power consumption On the other hand, even if electronic components with low power consumption are used, they will generate a certain amount of heat when they work, so the signal isolator needs to have a good heat dissipation effect
