Abstract

The utility model discloses an automotive heater which is composed of a heating chamber, a vacuum circulating pump, a temperature control device, a filter and a rectifier. When the temperature of an electric heating pipe in the electric heating chamber is raised to be 80 DEG C, the vacuum circulating pump is started to forcibly cause anti-freezing fluid in an engine to be fed into the heating chamber to be circularly heated. After 15 minutes, the engine temperature is caused to reach the starting temperature The utility model solves the problem that an automobile is not provided with a warm storehouse in winter and is difficult to start. The utility model is also suitable for large machines working in the open air in winter and line-haul automobiles. The utility model is provided with the rectifier which can charge for a battery which lacks electricity.

Description

Auto heater

The utility model relates to a kind of device of motor car engine preheating.

Winter cold area, the motor of Motor Vehicle such as automobile, tractor is because the low difficulty that starts of temperature, the water cycle before now general Motor Vehicle has replaced with antifreeze liquid, but subzero below 20 ℃ the time, the antifreeze liquid temperature is low excessively, motor vehicle starting is difficulty still.

The purpose of this utility model is that a kind of motor car engine that makes of design heats, and reaches the device of quick startup.

For solving above-mentioned task, the utility model is made up of heating chamber, vacuum cycle pump, temperature controlling device, filter cleaner and rectifier.

Heating chamber is made up of inner casing and thermal insulation layer, and heating chamber inside is provided with two electric heating tubes, and heating chamber links to each other with the vacuum cycle pump by connecting tube, on heating chamber and the vacuum cycle pump return pipe and intake pipe is set.

After adopting said structure, the vacuum cycle pump can be forced in-engine antifreeze liquid is sucked the heating chamber heating, and the heating body that elevates the temperature.

Describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the state of cutting open of plan view of the present utility model;

Fig. 2 is the state of cutting open of plan view of the present utility model;

Fig. 3 is a fundamental diagram of the present utility model;

As shown in the figure, the utility model is made up of heating chamber 1, vacuum cycle pump 2, temperature controlling device, filter cleaner 5 and rectifier 6.Heating chamber is made up of inner casing 14 and thermal insulation layer 18 two electric heating tubes 15 is set in the heating chamber, heating is precious to be linked to each other with vacuum cycle pump 2 by connecting tube 9, intake pipe 12 communicates with the vacuum cycle pump, return pipe 13 communicates with heating chamber, heating chamber 1, vacuum cycle pump 2 and rectifier 6 are arranged in the shell 16, thermosensitive element 3 communicates with pump relay 4 and temperature detect switch (TDS) 8, and heating chamber 1 connects the 220V power supply.

The utility model is connected with the pipeline that motor 11 leads to warm-air drier, the wire connected power of heating chamber, two electric heating tubes 15 heat simultaneously, when temperature is elevated to 80 ℃ of left and right sides, thermosensitive element 3 in the heating chamber 1 impels temperature detect switch (TDS) 8 closures, true recycle pump 4 circuit are connected, antifreeze liquid in the motor 11 is forced in the suction heating chamber by the Motorized vacuum recycle pump by filter cleaner 5, again antifreeze liquid is sent in the engine water jacket after being heated to a certain degree, through about 15 minutes circulation heating, the temperature of motor can be elevated to about 40 ℃ of temperature required when starting, according to user's needs, can use two electric heating tubes (2500W) also can use an electric heating tube (1250W) to carry out the heat insulation work circulation during heating simultaneously.

Because rectifier 6 is set on this heating equipment, rectifier is the 12V direct current with the 220V voltage commutation, is used for replenishing the electric weight of storage battery 7 temporarily.
