Oil way structure of transformer
ActiveCN112599337AAffect heat dissipationImprove cooling effectTransformers/inductances coolingTransformers/inductances coils/windings/connectionsTransformerEngineering
The invention discloses an oil way structure of a transformer. The oil way structure comprises a plurality of coils and wire cakes, wherein the coils and the wire cakes are sequentially arranged fromtop to bottom; oil baffles are arranged between the coils and the wire cakes; the oil baffles are arranged in a left-right alternating mode, so an S-shaped oil way is formed on the coils and the wirecakes; a first oil duct and a second oil duct are sequentially arranged on the inner sides of the coils and the inner sides of the wire cakes; a third oil duct and a fourth oil duct are sequentially arranged on the outer sides of the coils and the outer sides of the wire cakes; the first oil duct is divided into a lower first oil duct body and an upper first oil duct body, and the lower first oilduct body and the upper first oil duct body do not communicate with each other; and the third oil duct is divided into a lower third oil duct body and an upper third oil duct body. According to the invention, the oil way structure can effectively overcome the problems that since the insulation oil of an existing oil way structure flows through the whole coils, oil at the upper parts of the coils is heated by oil at the lower parts, oil temperature rises, and the heat dissipation, insulation life and operation safety of upper wire cakes are influenced.

Microporous ceramic heating body
PendingCN113925225AHigh affinityImprove wear resistanceTobacco devicesCeramicwarePorous ceramicsComposite material
The invention relates to the technical field of atomizers, in particular to a microporous ceramic heating body. The microporous ceramic heating body comprises a porous ceramic body and a heating circuit, a plurality of tobacco tar storage grooves are concavely formed in the top of the porous ceramic body at intervals, and the outer surface of the porous ceramic body comprises an atomizing surface located at the bottom of the porous ceramic body and an tobacco tar sealing surface located on the side wall of the porous ceramic body. The outer side surface of the tobacco tar sealing surface is coated with a glass glaze layer, the heating circuit is arranged on the atomizing surface, and the porous ceramic body is prepared by sintering a porous ceramic material. According to the microporous ceramic heating body, the plurality of tobacco tar storage grooves are concavely formed in the upper end face of the porous ceramic body, so that the tobacco tar storage amount and the contact area between tobacco tar and the porous ceramic body can be increased, and the tobacco tar can permeate to an atomizing surface through micropores in the side wall of the porous ceramic body to be atomized;the tobacco tar sealing surface of the side wall of the porous ceramic body is coated with the compact glass glaze layer; the problem that part of tobacco tar leaks through micropores in the side wall of the porous ceramic body can be effectively avoided.
