Photovoltaic control cabinet heat dissipation device

Abstract

This utility model relates to the field of photovoltaic heat dissipation technology. Specifically, it includes a main body mechanism, a heat dissipation mechanism, and a fixing mechanism. By pulling the clamping plate, the sliding plate can be extended within the sliding groove, allowing the clamping plate to be attached to both sides of the photovoltaic control cabinet that needs heat dissipation. This causes the heat-conducting fins to adhere to the photovoltaic heat dissipation cabinet. The rubber sheet increases the friction of the clamping plate, increasing the holding force. It can be installed without additional components to accommodate photovoltaic control cabinets of various sizes. The heat dissipation of the photovoltaic control cabinet is achieved through the adhesion of the heat-conducting fins. At the same time, the temperature sensing ring can detect the temperature of the photovoltaic control cabinet shell, causing the heat dissipation device to stop working when the temperature of the photovoltaic control cabinet is not high. When the temperature is high, the cooling fan and the heat sink, together with the hot spot cooler, allow the heat-conducting fins to absorb the heat from the surface of the photovoltaic control cabinet, thereby reducing the temperature.

The cabinet door is hinged to the cabinet body, and support rods are evenly distributed around the top wall of the cabinet. The rain cap is mounted on the support rods. The ventilation mechanism is located on the bottom wall of the cabinet body. The heat dissipation mechanism is symmetrically arranged on the two inner side walls of the cabinet body, located above the ventilation mechanism. The heater is symmetrically arranged on the two inner side walls of the cabinet body and located above the heat dissipation mechanism.
