The JRQ-FA type heater with fan is based on the actual situation of the user. For the traditional heater, the traditional heater mainly relies on radiant heat conduction. The heating and dehumidification effect is not ideal, and the surrounding components of the heater in the cabinet are thermally damaged. Based on the shape, the PTC heating element is used inside. The heating element has the incomparable advantages of traditional heating elements such as self-temperature control and constant temperature heating, no open flame, high heat conversion rate, minimal influence on the power supply voltage, and long natural life. The heater changes its own heating power with the change of external environmental conditions, that is, when the ambient temperature is low, the heat absorption is large, and the heater has good heat dissipation, its own power is large. On the contrary, it is small. A miniature axial flow fan is added to the outside. The airflow blown by the fan directly takes away the heat generated by the heating element, so that the air in the cabinet produces convective conduction. The overall temperature rises quickly, the heat distribution is uniform, and the dehumidification is rapid. The device has no negative effects. The heater always keeps working at a low temperature, which greatly extends its own life. This product is suitable for all kinds of high and low voltage switch cabinets, center cabinets, ring network cabinets, terminal boxes, box-type substations and other power equipment to remove moisture, prevent condensation, and increase the working environment temperature of electrical components.
