Abstract

The utility model discloses an air heater using waste heat from a motor vehicle engine, and relates to the technical field of the utilization of waste heat discharged by an engine in land transportation. The air heater using waste heat from a motor vehicle engine comprises a heating pipe, a sucking pump, a heat conveying pipe. A spiral pipe in the heating pipe is exactly sheathed on the exhaust pipe of the engine, the heat conveying pipe can be divided into a plurality of paths by shunting joints, and heat is conveyed to the heat needing places of a motor vehicle by the shunting heat conveying pipes. The utility model causes the waste heat of the engine of the motor vehicle to be fully utilized.

Description

Air heater using waste heat from motor-vehicle engine

The utility model relates to the UTILIZATION OF VESIDUAL HEAT IN technical field of the waste gas of engine emission in the land transport.

The driving engine of power actuated vehicle the time is wanted heat release in work, and this part heat is discharged after driving engine, have up to 200 ℃ about,, in air, still be not fully utilized at present with emission by exhaust pipe.

The purpose of this utility model is a kind of motor vehicle engine waste heat heater unit of design, and motor vehicle engine liberated heat when working is collected, and is used to produce warm braw, uses for power actuated vehicle.

This motor vehicle engine waste heat heater unit, form by heating pipe, air extracting pump and defeated heating coil, the heating pipe is to be equipped with in the heating pipe shell the inside with good thermal insulation property of being made by warm material to be coiled into spiral spiral tube and to form, the spiral tube internal diameter just in time can be sleeved on the external diameter of driving engine freeing pipe, and spiral tube is made up of the radial silk screen of settling in spiral tube shell and the spiral tube shell; Air extracting pump is made up of the electrical motor and the pump housing; Defeated heating coil is the good flexible tube of a kind of heat-insulating property, through tap, can be divided into the defeated heating coil of a few route shuntings and deliver to the place that power actuated vehicle needs heating installation.

The working process of this motor vehicle engine waste heat heater unit is, the hot gas that driving engine is discharged is by entering the heating pipe with exhaust pipe of engine bonded assembly air inlet pipe, owing in the spiral tube in the heating pipe radial silk screen is housed, has the good heat transfer conductive force, air in the heating pipe is heated equably, these heating installation are through freeing pipe, and be extracted in the pump housing of air extracting pump by air extracting pump through the air extracting pump air inlet pipe that is connected with freeing pipe by adaptor union, pass through the air extracting pump freeing pipe again, be transferred to by in the defeated heating coil of adaptor union bonded assembly, be transported to tap through adaptor union again, deliver to the place that power actuated vehicle needs heating installation through the defeated heating coil of shunting.

Accompanying drawing shows the embodiment of this motor vehicle engine waste heat heater unit, wherein:

Fig. 1 shows the block diagram of embodiment;

Fig. 2 shows the structural representation of air extracting pump among the embodiment;

Fig. 3 shows the front full sectional view of heating pipe among the embodiment;
