Description

A new type of cooling distribution cabinet

technical field

The utility model relates to the technical field of power distribution cabinets, in particular to a novel heat dissipation power distribution cabinet.

Background technique

The power distribution cabinet is the general name of the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and the circuits are less; the motor control center is used in the occasions where the load is concentrated and the circuits are many. The power is distributed to the nearby loads.

During the use of the existing power distribution cabinet, because it is in the external environment for a long time, the power distribution cabinet itself will continue to generate a certain amount of heat. In addition to the external ambient temperature, especially in summer, the external temperature is very high. Although the existing heat dissipation device of the power distribution cabinet has the function of heat dissipation, the heat dissipation is simply to drive the flow of air through the cooling fan to achieve the effect of heat dissipation, and this method will also make it easy for external sundries to enter the cabinet. As a result, the environment inside the cabinet is very dirty, which will seriously affect the normal use of the internal electronic components, and in cloudy and rainy days, the external rainwater will enter the cabinet. For the normal use of the cabinet, we propose a new type of cooling power distribution cabinet.
