[0004] The air circulation time inside the distribution cabinet is long and it cannot directly cool down. The long heat dissipation time can easily cause the temperature inside the distribution cabinet to rise, thus affecting the performance and life of the equipment. There are certain limitations.

[0005] Therefore, the utility model proposes a power distribution cabinet with a heat insulation structure. Utility Model Content

[0006] To this end, the utility model provides a power distribution cabinet with a heat insulation structure to solve the problems mentioned in the above background.

[0007] A power distribution cabinet with a heat insulation structure comprises a main shell of the power distribution cabinet, a partition, a ventilation component, a temperature control component and an electrical component. The partition is vertically arranged in the main shell of the power distribution cabinet and divides the inner cavity of the main shell of the power distribution cabinet into a working cavity and a cooling cavity. The partition plays a role in protecting the internal electrical equipment from mechanical damage and external environmental influences. The cooling cavity is used to reduce the internal temperature of the device. The drying cavity is used to reduce moisture retention and accumulation and reduce the humidity inside the power distribution cabinet. The front side of the main shell of the power distribution cabinet is a double-opening cabinet door. The electrical component is arranged in the working cavity. The temperature control component and the explosion-proof valve are arranged in the cooling cavity. When the internal pressure of the power distribution cabinet exceeds the set safety pressure threshold, the explosion-proof valve will automatically open to release the excessive pressure to prevent the container from exploding or rupturing. The ventilation component is arranged at the bottom of the partition, and a return air port is opened at the top of the partition.

[0008] Furthermore, the ventilation assembly includes a vent and an air circulation fan. The vent is arranged at the bottom of the partition to achieve air circulation in and out.

The refrigeration fin is a semiconductor refrigeration fin. One end of the refrigeration fin is arranged in the cooling cavity and the other end is connected to the radiator and is arranged outside the main shell of the distribution cabinet. The refrigeration fin utilizes the thermoelectric effect of semiconductor materials to achieve refrigeration, which can effectively reduce the temperature inside the distribution cabinet and achieve the effect of heat dissipation and cooling.

[0010] Furthermore, it also includes a heat insulation layer, which is arranged on the inner layer of the main shell of the distribution cabinet and is used to isolate external temperature changes and maintain a stable temperature inside the distribution cabinet.

[0011] Furthermore, the electrical components include a circuit breaker, a fuse, a transformer, a control panel, a controller and an electric load switch. The circuit breaker and the control panel are arranged at the same horizontal position as the return air outlet. The fuse connects the circuit breaker and the transformer. The transformer, the controller and the electric load switch are arranged at the same horizontal position as the ventilation component and are responsible for power distribution and circuit protection.

[0012] Furthermore, it also includes a drying plate, which is arranged in the cooling cavity and horizontally divides the cooling cavity. A desiccant is placed in the porous drying plate, which can convert moisture into water vapor and discharge it to the outside of the main shell of the distribution cabinet to achieve a drying effect.

[0013] Furthermore, the partition is made of aerogel material, which has extremely low thermal conductivity and excellent thermal insulation performance.

[0014] Furthermore, the thermal insulation layer is a rubber-plastic insulation board and is installed on the inner wall of the main shell of the power distribution cabinet by bonding, and has excellent thermal insulation and sound absorption properties.

[0015] Compared with the prior art, the beneficial effects of the utility model are: through the insulation layer, the external temperature is blocked, thereby reducing the impact of the external temperature on the internal temperature of the distribution cabinet; the ventilation component enables good air circulation inside the distribution cabinet, effectively solving the problem of temperature increase inside the distribution cabinet due to insufficient heat dissipation; the heat is transferred from the heat-generating electronic components to the radiator through the cooling plate, thereby achieving a cooling effect, and better solving the problem of temperature increase inside the distribution cabinet.
