Abstract

The invention relates to a water cooling structure of a microwave oven magnetron, which comprises a circulating water pipe, a water pump and fins, wherein the water pump is connected with the circulating water pipe; part of the water pipe is wound on the outer side of a positive electrode; and part of the outer side of the water pipe is sleeved with the fins. The water pipe is a copper pipe with large thermal coefficients. The fins sleeved on the outer side of the water pipe are made of aluminum alloy, are arranged on the water pipe alternately, and are vertical to the penetrating water pipe.Under the action of the water pump, the water in the water pipe flows circularly, wherein the cold water entering the water pipe on the outer side of the positive electrode absorbs the heat of the positive electrode and is heated into hot water, the hot water flows to the water pipe of which the outer side is sleeved with the fin to radiate into cold water again, the cold water absorbs the heat ofthe positive electrode and is heated again, and is cooled by the fin radiation again, and the water circulates to radiate and cool the magnetron in turn. The fan blows air to the fins to intensify the convection radiating and improve the radiating and cooling effect of the magnetron.

Description

technical field [0001] The invention relates to a magnetron of a microwave oven, in particular to a heat dissipation and cooling structure of the magnetron of a microwave oven. Background technique [0002] A microwave oven is a household appliance cooker that uses high-frequency microwaves to heat food. It heats and cooks food through the frictional heat generated by the violent vibration of food molecules under the action of high-frequency microwave radiation. When cooking in a microwave oven, the microwave penetrates the food and can heat the inside and outside at the same time, which has many advantages of high efficiency, fast speed and convenient application. Therefore, microwave ovens have gradually become widely used household appliances. The appearance of the microwave oven is in the shape of a cuboid, the front of the cuboid casing has a furnace door, and an operation key is arranged on one side of the furnace door. A furnace cavity is formed inside the shell, an...
