Specific embodiment

The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:

As shown in Figs. 1-5, a kind of novel high-frequency transformer, including transformer case 1, mounting seat 2, metal outlet Ge Lan 3, insulation crust 4 and transformer body 6.

Oval-shaped cavity 11 is used inside transformer case 1, is placed transformer body 6, transformation in oval-shaped cavity 11 6 shape of device ontology is designed using elliptical shape, multiplied by variation coefficient on the basis of original calculating parameter, guarantees that transformer mutual inductance is defeated It is identical as theoretical value to enter output voltage ratio.9 outer surface of transformer coil and transformer case 1 can be increased using ellipsoidal structure Between contact area, shorten transformer body 6 and transformer case 1 between the two at a distance from, reduce the distance of heat transfer, Increase the ability of heat dissipation.1 peripheral hardware of transformer case is in respect of radiator shutter 10, so that the fever of transformer has one preferably to dissipate Heat condition, to increase the available capacity of transformer.Transformer case 1 uses cast aluminium shell, is guaranteeing the same of integral strength When reduce the weight of transformer, provide convenience for the installation maintenance in the subsequent use process of product.In insulation crust 4 and become Transformer oil or insulating cement 5 are filled up in gap between depressor ontology 6.
