Description

A high and low voltage switch cabinet with stable heat dissipation

technical field

The utility model belongs to the technical field of switch cabinet equipment, in particular to a high and low voltage switch cabinet with stable heat dissipation.

Under normal circumstances, exhaust fans are installed on the high and low voltage switchgear to achieve cooling. Fans with axial flow fans are commonly used, but when the fan is working, external dust, oil and harmful gases will also enter the high and low voltage switchgear. Inside, it is electrostatically adsorbed on the surface of the circuit board, which accumulates over time, causing certain corrosion to components, circuits, etc., and at the same time affecting its heat dissipation. The accumulated dust can also cause a short circuit in the high-voltage part of the circuit board when wet. The longer the working time of the high and low voltage switchgear, the more prominent the above problems, and when accumulated to a certain extent, it will cause a sudden failure of the control part.

However, since the common high and low voltage switch cabinets on the market exchange the air inside the chassis with the outside air to achieve cooling, there is still the problem of dust, oil and harmful gases entering the chassis and short circuiting the circuit boards.
