Circulating double-track heat dissipation type signal isolator

Abstract

The invention discloses a circulating double-track heat dissipation type signal isolator, and belongs to the field of signal isolators. The circulating double-track heat dissipation type signal isolator comprises a shell, wherein the side end of the shell is fixedly connected with a plurality of uniformly distributed double-track heat dissipation discs, and the interior of a vertical disc is provided with an inner cavity, a heat absorption channel and a heat dissipation channel. According to the invention, by arranging double-track heat dissipation discs, one part of the double-track heat dissipation discs is located in a shell and absorbs heat in the shell, the other part of the double-track heat dissipation discs communicates with the outside and transmits the heat to the outside, a two-way loop is formed between the heat transmission inside and outside the shell through a straight cylinder rail and a bent cylinder rail so as to achieve internal and external circulation movement of a heat transfer ball and continuously transmit the heat to the outside, and in the circulating movement process of the heat transfer balls, induced draft blades are triggered to flap back and forth to improve air flowing, so that efficient heat dissipation of the interior of the shell is fully achieved through continuous heat transfer and rapid air convection.

Description

technical field [0001] The invention relates to the field of signal isolators, in particular to a circulating double-track heat dissipation signal isolator. Background technique [0002] The signal isolator is a kind of linear optocoupler isolation principle, which converts the input signal to the output. The input, output and working power are isolated from each other, especially suitable for use with equipment and meters that require electrical isolation, and are an important part of industrial control systems. [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, causing 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 d...

[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
