The environment-friendly and energy-efficient fuel tank heater

Technical field

The utility model relates to a kind of automobile-use fuel tank heater, particularly a kind of environment-friendly and energy-efficient fuel tank heater that utilizes engine cycles water that fuel oil in the fuel tank is heated.Be applicable to various motor vehicle.

Background technique

At present, the power source that all kinds of Motor Vehicle use is included as two kinds of gasoline and diesel oil, yet these two kinds of fuel oils but have different effects in the using process in the winter time, especially diesel oil.In the northern area of China, along with winter temperature reduces, the mobile performance variation of fuel oil is affected the speed of a motor vehicle, and causes the automobile starting difficulty.As, in the winter time, " 0 " number diesel oil begins to separate out wax, retrogradation can't be used, and will change " 10 " number diesel oil when temperature drops to subzero 10 degree into during the left and right sides, will change " 20 " number diesel oil when temperature drops to subzero 20 into when spending, temperature descends again, will change " 35 " number diesel oil into, because negative font size diesel-fuel price is higher, so caused the increasing of operating cost.For addressing the above problem, the existing electric heater that uses heats fuel oil in the fuel tank, and such electric heater is electric heating wire to be worn porcelain tube place the frame endoporus, fills the frame endoporus and seals formation through the welding end by heat-conducting medium magnesia.Yet this electric heater exist the temperature rise time long, the thermal efficiency is low, maintenance difficult, user cost height, defective that safety coefficient is low.Because there is above-mentioned defective in electric heater, so some heaters are guided to hot-water line in the fuel tank at present, when the overheated water pipe of flow of hot water with fuel Heating, but heating effect is relatively poor, what also have is designed to volute with hot-water line, though heating effect makes moderate progress complex manufacturing technology, above-mentioned hot-water line requires also very high at mounting process when the fuel tank, and the joint is easily loosening and break down.

The model utility content

The purpose of this utility model is the environment-friendly and energy-efficient fuel tank heater that uses the low grade oil-fired vehicle to require for the suitable time in severe winter that a kind of reasonable in design is provided, fundamentally solved the existing electric heater temperature rise time long, the thermal efficiency is low, maintenance difficult, user cost height, problem that safety coefficient is low, compare with existing heater, has the advantage that heating properties is good, preparation process is simple, easy to maintenance, simultaneously, utilize engine cycles water that fuel oil in the fuel tank is carried out the purpose that heating principle has reached energy-saving and environmental protection.

The technical solution of the utility model is: this environment-friendly and energy-efficient fuel tank heater comprises outlet pipe and the return pipe that is connected with engine-cooling system, be arranged on the heating pipe of fuel tank internal, its technological points is: described heating pipe is the U-shaped water pipe that is connected respectively with described outlet pipe and return pipe, the water intake of described U-shaped water pipe and water outlet utilize flange plate to be fixed on the described fuel tank outside, in the bottom of described U-shaped water pipe is provided with, externally threaded support tube, described support tube utilizes locking nut to be fixed on the lower end surface of described fuel tank, described support tube port is provided with the plug that discharges water, the tubing string outside, described U-shaped water pipe both sides is set with fuel sucking pipe, described fuel sucking pipe upper end is welded on the described flange plate, and utilizes transport pipe connecting the oil outlet tube that is provided with on the described flange plate jointly.

On the outer wall of described support tube adjusting nut is set, between described adjusting nut and the described fuel tank lower end surface sealing gasket is set.

Described flange plate is fixed flange and the moving flange plate that is separately positioned on inside and outside both sides, described fuel tank upper-end surface, described fixed flange and moving flange plate utilize screw on the upper-end surface of described fuel tank, between described fixed flange and the described fuel tank upper-end surface pad are set.

The positive technique effect of advantage of the present utility model and its generation is: be set with fuel sucking pipe in the U-shaped water pipe both sides tubing string outside, and utilize transport pipe connecting the oil outlet tube that is provided with on the flange plate jointly.So the hot water of engine-cooling system enters into the U-shaped water pipe by outlet pipe, water intake, flow back to the cooling system of motor again from water outlet, return pipe.During this period, the fuel oil in the suction sleeve is subjected to the heating of circulating water in the U-shaped water pipe, is pooled to the oil outlet tube that is provided with on the flange plate then, supplies with and gives high pressure oil pump.Fundamentally solve the existing electric heater temperature rise time long, the thermal efficiency is low, maintenance difficult, user cost height, problem that safety coefficient is low, its reasonable in design utilizes engine cycles water that fuel oil in the fuel tank is carried out the purpose that heating principle has reached energy-saving and environmental protection.In the winter motor-driven vehicle going process, every use 100kg fuel oil will be saved the 18-20 yuan.Compare with existing heater simultaneously, its heating properties is good, preparation process is simple, easy to maintenance.
