Problems solved by technology

[0003] At present, the inverters are miniaturized, and fans are generally used for active heat dissipation, but due to the large size of the fans, they will generate noise when working, and at the same time absorb dust, which will affect the internal heat dissipation effect.
[0004] In addition, because the external inverter needs to be fixed by bolts, it is easy to loosen after long-term use, which affects heat dissipation
[0005] Existing, in order to prevent dust from entering, thermally conductive glue is added between the case and the inverter, but this method has limited heat dissipation capacity

Embodiment approach

[0063] Embodiment: When using the device designed in the present invention, the heat emitted by the inverter 9 is first blown by the built-in fan 10 through the front inner wall of the housing cover 2, and then moves backward from the gap between the fixed housing 8 and the housing 1 flow, and finally flow to the rear end face of shell 1.

[0064] When not in use, under the action of the spring 49, the motor 29 housing 1 is stationary, the second gear 19 is engaged with the fourth gear 28; the fifth gear 44 is engaged with the sixth gear 46; when the control motor 29 works, the output shaft drives The indoor fan works; the casing 1 of the motor 29 reversely rotates relative to the output shaft and pulls the pull rod 45, so that the pull rod 45 pulls the rotating sleeve 50 to slide toward the side away from the fourth gear 28, and the rotating sleeve 50 slides through the rotating ring 42 to drive the second rotating shaft 47 toward As the side slides away from the fourth gear ...

Abstract

The invention belongs to the technical field of inverter heat dissipation, and particularly relates to inverter heat dissipation equipment for a closed environment, which comprises a shell, a shell cover, a bracket, a fixed shell, an inverter, an internal fan, an external fan and a motor. And due to the design of the special internal circulation structure, the heat dissipation efficiency is high, and the heat dissipation effect is good. In addition, the wind direction of the tunnel is fully utilized, so that the heat dissipation area forms three areas with different temperatures; in the heat dissipation process, hot air flow firstly passes through the heat dissipation area with the highest temperature, then passes through the heat dissipation area with the middle temperature height and finally passes through the heat dissipation area with the lowest temperature for heat dissipation, and a good heat dissipation effect can be achieved through the heat dissipation sequence, namely countercurrent flow heat exchange.

Description

technical field [0001] The invention belongs to the technical field of inverter heat dissipation, and in particular relates to an inverter heat dissipation device used in a closed environment. Background technique [0002] With the development of cities, the construction and use of subways are becoming more and more widely used. There are more and more electronic controls in tunnels, and inverters are commonly used in electronic controls. [0003] At present, the inverters are all miniaturized, and fans are generally used for active cooling. However, due to the large size of the fans, they will generate noise during operation and inhale dust at the same time, affecting the internal heat dissipation effect. [0004] In addition, because the external inverter needs to be fixed by bolts, it is easy to loosen after long-term use, which affects heat dissipation. [0005] Existing, in order to prevent dust from entering, thermally conductive glue is added between the casing and t...
