Description

The special-purpose fuel tank heater of diesel engine

Technical field

The utility model belongs to the improvement of diesel oil heating equipment structure, makes it reduce the special-purpose fuel tank heater of stickiness, particularly diesel engine to the diesel oil heating specially at low temperature.

Background technique

At present, the fuel tank bavin that diesel oil is housed mostly needs to heat by the conventional electric heating device or by the burning heater of incendivity release heat, but the diesel oil of electric heater or burning heater heating thickness also makes its effect of thawing unsatisfactory, be that heating time is long, power consumption, can not effectively heat the diesel oil in the fuel tank at rational position, can only be to the liquefaction of thawing of uniform diesel oil, finally cause diesel engine fully not burn and enter the diesel oil of its cylinder body, cause combustion efficiency low, waste limited diesel oil resource, and cause too high carbon emission amount, atmosphere pollution.

Summary of the invention

The purpose of this utility model is to provide a kind of diesel engine special-purpose fuel tank heater, it is simple and reasonable for structure, can effectively heat the diesel oil that does not thaw in the fuel tank at rational position, and make it to liquefy immediately to transfer in the engine cylinder-body, heating time is shorter, energy-conservation, consumption reduction.

The purpose of this utility model is achieved in that the special-purpose fuel tank heater of a kind of diesel engine, comprise water jacket that is arranged on the diesel engine cylinder outer wall and the recycle pump that is installed on its cylinder body by this diesel engine drives work, water jacket communication loop pump pump chamber, form by bimetallic tube and heat radiation jar, bimetallic tube is made of inner core tube and outer sleeve, inner core tube is arranged in the outer sleeve and looping tube chamber between the tube wall of its tube wall and outer sleeve, the bottom is installing the heat radiation jar in fuel tank, the flow tube one end that is provided with in the heat radiation jar is communicated with the inner chamber of fuel tank by the mouth of pipe that is provided with on the far-end tank skin of heat radiation jar away from fuel tank one side box wall, the flow tube the other end passes near-end tank skin and this side box wall of fuel tank of heat radiation jar close this side box wall of fuel tank and is communicated with the filler opening of diesel engine by inner core tube, heat radiation jar jar chamber is communicated with a pair of oil guide pipe that passes this side box wall of fuel tank by a pair of through hole that is provided with on its near-end tank skin, wherein an oil guide pipe directly is communicated with a port of water jacket, and another oil guide pipe is connected the another port of water jacket by outer sleeve and the tube chamber between the inner core tube.

When using the utility model, earlier motor is opened hot voluntarily machine, the thermal energy conduction that hot machine produced is to the antifreeze liquid that is positioned at the water jacket that is provided with on its cylinder body periphery wall, the antifreeze liquid that carries heat is passed through by crossing the tube chamber between outer sleeve and the inner core tube or directly entering in the heat radiation jar by oil guide pipe by the recycle pump pump, and the heat that carries released by heat radiation jar tank skin conduct to the diesel oil that does not thaw in the fuel tank, make preferentially the thawed liquefaction and directly enter diesel engine burning work done of the diesel oil that is in around the heat radiation jar by the inner core tube that is built in the flow tube in the heat radiation jar and is placed on the outer bimetallic tube of fuel tank, flowing to through inner core tube in the process of diesel engine, the antifreeze liquid of one-way flow also can be incubated the effect of (or even heating) to the liquefaction diesel oil that flows to diesel engine through inner core tube between outer sleeve and inner core tube tube wall, and antifreeze liquid is the motion flow of heat release jar is absorbed heat and dispelling the heat in the execution that moves in circles under the drive of recycle pump in water jacket in then.This shows that the utility model is simple and reasonable for structure, can effectively heat the diesel oil that does not thaw in the fuel tank, and make it to liquefy immediately to transfer in the engine cylinder-body that heating time is shorter, energy-conservation, consumption reduction at rational position.
