Abstract

An engine low temperature self-heating facility belonging to engine preheating device is provided, which comprises a water pump, a heater and an AC contactor. Wherein, the heater is an enclosed housing provided with a water inlet, a water outlet and a heating pipe; the water outlet of the water pump is switched on by the water inlet of the pipeline and the heating pipe; the heating pipe of the heater and the wire connecting terminal of the water pump are connected with the AC contactor respectively. The utility model, with simple operation and convenient use, is effective to solve the long-existing difficulty of starting up the motor vehicles during winter in the north China.

Description

Motor low temperature automatic heating device

Technical field:

The utility model belongs to motor low temperature automatic heating device.

Background technique:

The north of china in winter temperature of China is low, and motor vehicle are parked a night in the open, just starts very difficulty, especially diesel-oil vehicle morning, and the startup problem in morning has become a long-standing difficult problem in the winter time.In order to solve this difficult problem, people take to annotate boiling water, spray primer fluid, solve this problem, these method inconvenient operation with methods such as blowtorch or bavin standing grain baking fuel tank shell bottoms in water tank, also dangerous, also waste resource, befouling environment is particularly very easily damaged motor.

Summary of the invention:

The utility model aims to provide a kind of motor vehicle Preheating unit simple to operate, and the heating pipe of this Preheating unit and vehicle is connected, and the logical power supply of going up makes the water Heating Cyclic in warm braw water tank and the engine cylinder-body inner water sleeve, reaches the purpose of warm-up the engine.

The realization the technical solution of the utility model is: comprise water pump, heater, A.C. contactor, heater is the sealed mode casing that is provided with water intake, water outlet, heating pipe is set in the casing, the termination of heating pipe is stretched out outside the casing and is connected with A.C. contactor by electric wire, the water outlet of water pump is connected by the water intake of pipeline and heater, and the tenminal block of water pump is connected with A.C. contactor.

The utility model is installed on the heating pipe of vehicle, when using the utility model, start power switch, water pump and heater are worked simultaneously, water pump with the water pump in engine cylinder-body inner water sleeve and the warm braw water tank in heater, after the heating pipe heating, enter into warm braw water tank and engine cylinder-body inner water sleeve, water pump---heater---warm braw water tank---engine cylinder-body inner water sleeve---water pump, so circulation, temperature up to motor reaches certain temperature, enters working state, and vehicle can start.
