Abstract

The utility model discloses an automobile low temperature starting preheater, comprising a water heating part, an oil electric heat pipe, an electric outlet and a valve, etc. The utility model is an electric preheater enabling the automobile to start quickly in low temperature environment in cold winter via preheating the circulating water and the engine oil. The utility model is arranged on the vehicles and has the advantages of a simple structure, the convenient installation and the power supply via external power or automotive battery. The utility model unties the difficulties in the low temperature starting of the vehicles, in particular the low range vehicles, trucks, agricultural vehicles and tractors, etc., thus reducing the supernormal wear of the parts thereof caused by low temperature starting, prolonging the life thereof and reducing the failure rate. The utility model is suitable for the installation and application of various automobiles, diesel vehicles, cars, buses, freight cars, agricultural vehicles, tractors, etc. and is suitable for the production in automobile works, agricultural vehicle works and repair shops.

Description

Automobile cold-starting preheater

Affiliated technical field

The utility model relates to a kind of automobile cold-starting Preheating unit, especially can electricity consumption warm-up cycle water and machine oil, and make automobile at the preheater of starting smoothly in winter of cold.

Background technique

At present, though automobile at the cooling system antifreeze liquid of having annotated in the winter of cold, this can only keep cooling liquid low temperature not freeze, and the temperature of antifreeze liquid and machine oil is under the situation that does not have the warming up storehouse, its temperature is identical with ambient temperature.The winter of severe cold, some region temperature can reach-20 ℃--about 50 ℃, low like this temperature, the vehicle starting difficulty, particularly some low-grade sedan-chairs, visitor, goods, load-carrying, agricultural vehicle, tractor etc. are before cold-starting, generally all manually with heating oil sumps such as blowtorch, carbon fire, make circulating liquid intensification preheating in machine oil and the cylinder sleeve, could start smoothly, so not only dangerous not only time-consuming, effort but also inconvenient.

Summary of the invention

For automobile can be started smoothly in the winter of cold, the utility model provides a kind of automobile cold-starting preheater, and this preheater can be used electric heating automobile circulating water and machine oil, and automobile is started smoothly.

The technological scheme that its technical problem that solves the utility model adopts is: this preheater is made up of water heating element, oily electric heating tube, power socket, valve, the water heating element has the shell of sealing, in electric heating tube is arranged, return pipe and outlet pipe are arranged on the shell, outlet pipe is connected with the high water level point of automobile circulating water, return pipe is received on the following water level point of automobile circulating water by valve, the oil electric heating tube is fixed in the automotive oil drain pan, and oily electric heating tube is connected with power socket with power line with the interior electric heating tube of water heating element.Before vehicle starting, open valve earlier, make to be full of in the water heating element behind the circulating liquid and insert power supply by power socket again, at this moment water heating element Heating Cyclic liquid, natural circulation after circulating liquid heats up, oil electric heating tube heating oil sump inner engine oil, when machine oil and circulating liquid reach the normal starting temperature, deenergization, throttle down can be start-uped a car smoothly.

The beneficial effects of the utility model are, solved the preceding pre-heat problem of automobile cold-starting, particularly place in the open and do not have under the warming up storehouse cold-starting situation of difficult in the winter of cold, can make the smooth quick starting of automobile, to some low-grade sedan-chairs, visitor, goods, load-carrying, agricultural vehicle, cold-startings such as tractor are very suitable especially, both removed the heat cost of building garage and winter from, reduced the extraordinary wearing and tearing of parts that cold-starting causes again, and motor live time is prolonged life, rate of fault reduces.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified

As accompanying drawing is structure of the present utility model and electrical connection diagram, among the figure: 1. water heating element, 2. oily electric heating tube, 3. electric heating tube, 4. power socket, 5. outlet pipe, 6. valve, 7. return pipe, 8. screw thread, 9. sealing gasket, 10. screw thread, 11. sealing gaskets, 12. delivery hoses, 13. the backwater flexible pipe, 14. electric heating tube wiring terminals, 15. oily electric heating tube wiring terminals, N. zero-power line, L. power supply phase line, G. ground.

Embodiment

In the accompanying drawings, water heating element (1) has the metal shell of sealing, outlet pipe (5) and return pipe (7) are arranged on the shell, outlet pipe (5) return pipe (7) communicates with water heating element (1) inner cavity, electric heating tube (3) by screw thread (8) and sealing gasket (9) fixing seal in water heating element (1) cavity, oil electric heating tube (2) by screw thread (10) and sealing gasket (11) fixing seal in the automotive oil drain pan, certainly oil sump need be opened a hole that internal thread is arranged and match with screw thread (10) (or with the former clear opening of putting), outlet pipe (5) by delivery hose (12) and automobile circulating water preferably the high water level point of short circle (this example is on the flexible pipe of warm braw heat exchanger) be connected, return pipe (7) is received on the following water level point (this example is on the auto pump water supply hose) of automobile circulating water by valve (6) and backwater flexible pipe (13), electric heating tube wiring terminal (14) and oily electric heating tube wiring terminal (15) are connected on the zero-power line (N) of power socket (4) by power line, on the power supply phase line (L), the metal shell of water heating element (1) and oily electric heating tube (2) connects the metal car body and receives on the ground of power socket (4) (G) again, water heating element (1) is fixed under the motor car engine cylinder sleeve below the water level, outlet pipe (5) should be last, return pipe (7) should be following, this routine electric heating tube (3) is 220V1kw, oil electric heating tube (2) is 220v0.8kw, open valve (6) before the vehicle starting earlier, again the 220v power supply is received on the socket (4) after being full of circulating liquid in the water heating element (1), at this moment oil sump inner engine oil and circulating liquid are heated simultaneously and heat up, the circulating liquid natural circulation, when machine oil and circulating liquid reach the normal starting temperature, deenergization, throttle down (6) can be start-uped a car smoothly.
