Description

Preheating type oil pan Technical Field The utility model belongs to the technical field of engine parts, and relates to a preheating type oil pan. Background In the field of design and application of internal combustion engines, the oil pan serves as an important component of the engine and plays a key role in storing lubricating oil. The engine oil pan not only ensures lubrication among all parts in the engine, but also takes heat away from a mechanical assembly running at a high speed through a circulating system, so that damage caused by overheating is prevented. However, under low temperature conditions, the oil pan in conventional designs is faced with serious challenges. When the external air temperature is reduced to-10 ℃ or even lower, the viscosity of the engine oil in the oil pan is obviously increased, the fluidity is poor, the engine is difficult to start, and meanwhile, the oil pump supplies oil to each friction surface of the engine smoothly, so that the risk of mechanical abrasion is increased, and the service life of the engine is shortened. To solve the above-mentioned problems, the prior art generally adopts an external heater to perform a preheating treatment on the oil pan. Specifically, these heating devices are mounted on the outer wall of the oil pan, and indirectly raise the temperature of the internal engine oil by heating the outer shell. However, this method has a significant limitation in that the preheating time is long due to low heat transfer efficiency, and the working temperature of the engine oil cannot be rapidly increased to a proper range, thereby affecting the instant starting performance and the running efficiency of the engine. Disclosure of utility model The utility model aims to provide a preheating type oil pan, which can rapidly heat lubricating oil in the oil pan, and can effectively shorten the preheating time so as to meet the requirement of rapid starting of an engine. In order to solve the technical problems, the utility model provides a preheating type oil pan, which comprises an oil pan with openings at the upper end and the lower end, wherein the lower end of the oil pan is detachably connected with a bottom cover, the upper end of the bottom cover is upwards provided with a supporting seat in the oil pan, the upper end of the supporting seat is provided with an electric heating plate, the electric heating plate is internally provided with an electric heating wire which is in a serpentine arrangement, the outer side of the electric heating plate is provided with a plurality of heat conducting fins, the bottom of the bottom cover is provided with a connector, the electric heating wire passes through the supporting seat and is electrically connected with the connector, the bottom cover is provided with an oil drain hole, the lower end of the bottom cover is downwards provided with an oil drain pipe communicated with the oil drain hole, the inner wall of the oil drain pipe is provided with internal threads, the oil drain pipe is in threaded connection with an oil drain bolt, and the oil drain bolt extends out of the oil drain pipe and is provided with a bolt head. Through adopting above-mentioned technical scheme, when the lubricating oil in the oil bottom box is sticky owing to low temperature is led, and the electric heater strip circular telegram intensifies, makes the electrical heating dish intensify, heats the lubricating oil in the oil bottom box through heat conduction fin inside fast to the impurity that produces in the lubricating oil is lived to sink to the bottom of oil pan, because the electrical heating dish blockked, is difficult for being carried to drive mechanism along with lubricating oil by circulation system in, prevents that impurity from mixing into the inner structure of wearing and tearing engine in the lubricating oil. The oil pan is further provided with an upper mounting edge at the edge of the upper end of the oil pan, and a plurality of upper mounting holes penetrate through the upper mounting edge. The oil pan is further provided with a lower mounting edge at the edge of the lower end of the oil pan, a plurality of lower mounting holes are formed through the lower mounting edge, a plurality of connecting holes corresponding to the lower mounting holes one by one are formed at the edge of the bottom cover, and the bottom cover is connected with the lower end of the oil pan through connecting bolts penetrating through the corresponding lower mounting holes and the corresponding connecting holes. The utility model is further arranged that the upper end of the edge of the bottom cover is provided with a rubber sealing ring matched with the lower mounting edge. The utility model further provides that one side of the bolt head is provided with a sealing rubber ring sleeved with the oil drain bolt. The utility model further provides that the electric heating plate and each heat conducting fin are made of polyimide. Compared with the p
