AI Technical Summary
The heat dissipation effect of traditional distribution boxes is poor. When the hot air naturally rises due to density differences, it forms cyclone interference with forced convection in the horizontal direction, resulting in a high temperature in the top area of the box and insufficient heat exchange efficiency of the fixed heat dissipation fin set.
A distribution box with chimney-type heat dissipation channel is designed. By opening air inlets on the bottom plate and exhaust outlets on the top plate, a vertical heat dissipation channel is formed. Combined with the heat dissipation adjustment mechanism, including telescopic rods, frames, brackets and heat dissipation fins, the angle and position of the fins are adjusted to increase the air contact range, and the chimney effect is generated by natural convection to enhance the heat dissipation effect.
It improves the heat dissipation effect of the internal equipment of the distribution box, reduces temperature inhomogeneity, enhances the heat exchange efficiency of the heat dissipation fins, and ensures the stable operation of the equipment.

Abstract
Description

[0002] With the rapid development of the construction of smart grids, as the core carrier of the power distribution system, a large number of heat-generating devices such as circuit breakers, contactors, and intelligent control modules are integrated inside the distribution box. During continuous operation, the temperature rise of the equipment can reach 60 - 80 °C. If the heat dissipation is poor, it will lead to problems such as accelerated aging of insulating materials and performance drift of electronic components. Most traditional distribution boxes adopt a horizontal heat dissipation mode with side wall openings and axial fans. This design has the following defects: when hot air naturally rises due to density differences, it forms a cyclone interference with the forced convection in the horizontal direction. Measured results show that the temperature in the top area of the box body is 15 - 20 °C higher than that in the bottom area; due to the limited installation position of the fixed heat dissipation fin group, the heat exchange efficiency is less than 30% of the theoretical value, resulting in the technical problem that the heat dissipation effect of the distribution box is generally poor.

After the cold air enters the interior of the distribution box 10 from the air inlet 17, it exchanges heat with the equipment main body 30 inside the distribution box 10, and the heated air after heat exchange is discharged from the air outlet. A natural convection is formed through the vertical heat dissipation channel of inhaling cold air at the bottom and discharging hot air at the top, thereby generating a chimney effect and improving the heat dissipation effect of the equipment main body 30 inside the distribution box 10. In addition, a heat dissipation fan 15 is arranged on the top plate 14, and the air inlet end of the heat dissipation fan 15 is installed at the air outlet, and the air flow effect inside the distribution box 10 is improved by adding the heat dissipation fan 15, further improving the heat dissipation effect.
