Example Embodiment

[0019] The features and technical content of the present invention will be further described in detail below in conjunction with preferred embodiments and specific implementation methods.

[0020] Please refer to figure 1 , a transformer cooling device for a microwave oven and a manufacturing method, mainly contain a container, cooling oil placed in the container and a transformer, the container is composed of an upper plate 1, a lower plate 2 and a container body 3, the cross-section of the container body wall It is corrugated 4, and the upper plate 1 and the lower plate 2 are fixedly connected to the upper and lower ports of the container body respectively to form a closed container with four corners in an arc shape. The container can also be round or other polygonal. The upper plate 1 and the lower plate 2 Rib 6 is provided. The upper surface of the upper plate 1 is provided with a connecting terminal 7 and an oil filling port 8. The transformer 5 is placed in the contain...

Abstract

The invention belongs to a microwave oven transformer cooling device and the manufacturing method. The container is made up of upper board, a subjacent board and the container body. The cross section of the container wall is corrugated type, the upper board and the subjacent board are fixed on the two ports of the container to form a sealed container, a connecting terminal and a oil inlet are arranged on the surface of the upper board, the transformer is arranged in the container, and connected to the upper board and the subjacent board, the input and output wire of the transformer are connected to the connecting terminals. The manufacturing method of the cooling device has punching, forming, welding assembling connecting terminals sealing and engaging welding the transformer extracting vacuum oil pouring sealing the inlet. The advantage of the invention are: the cross section of the container is corrugated type, thus it can increase the contacting area between the transformer container and the cooling oil greatly, at the same time, it upgrades the container external area contacting to air greatly, and thus the transformer can be cooled fully.

Description

technical field [0001] The invention belongs to a transformer cooling device, in particular to a transformer cooling device for a microwave oven and a manufacturing method. Background technique [0002] In order to eliminate the high temperature and noise generated on the silicon steel sheets and coils of high-voltage transformers used in microwave ovens, cooling oil is usually used for cooling. The structure of the disclosed technology (refer to figure 2 ) is a container whose outer wall is fixedly connected with the cooling plate 1 to contain a transformer composed of coils and silicon steel sheets. Cooling oil is injected into the container, and the cooling oil absorbs the high temperature generated by the transformer and emits it to the outside of the container. The heat dissipation effect of this structure is not good. The reason is that the heat dissipation plate 1 is installed on the outer wall of the container afterward, and the cooling oil contacts the inner wall ...
