Abstract
The utility model relates to a high voltage capacitance protector for microwave heater. The utility model comprises an upper bracket (1) and a lower bracket (2), wherein the upper bracket (1) is provided with a plurality of radiating fins (1A). The place between the upper and the lower brackets is provided with a high-voltage capacitor (3), whose lower surface contacts with the upper surface of the lower bracket (2), and upper surface contacts with the lower surface of the upper bracket (1). In using the radiating fins, the high voltage capacitance protector for microwave heater expands the heat radiation area of the high-voltage capacitor, enlarges the heat dissipating capacity, and enables the heat emit into the air through the upper bracket of the radiator. In addition, the thermal conduction silica gel, which is spread on the contact faces of the upper and lower brackets of the high-voltage capacitor and the radiator, can make the capacitive heat spread to the radiator better. Furthermore, the utility model can enable the high-voltage capacitor be nicely fixed on the flat plate of the lower bracket, so that the high-voltage capacitor can be more stable. The high voltage capacitance protector for microwave heater prolongs the service life of the high-voltage capacitor by effectively solving the difficult problem that temperature always rises during the work time of the high-voltage capacitor.
