Abstract

The utility model relates to a warm air device by utilizing the residual heat of the car tail gas. The utility model comprises a pipeline which is connected with a car gas exhaust pipe and a heat collection tank. The middle of the heat collection tank is separated by a partition plate. The tank body of the lower part of the heat collection tank is a heat storage tank, and the interior of the tank body is provided with a heat conduction device. After the tail gas is connected with the pipeline, the tail gas is backwards bifurcated into two pipelines. One pipeline is a straight exhaust pipeline, and the other pipeline is penetrated through the tank wall and is inserted into the heat storage tank. One side of the upper tank body of the heat storage tank is provided with a connection pipe which is connected with a blower, and the corresponding side of upper tank body of the heat storage tank is provided with a warm air delivery pipeline which is connected with the interior of the car body. The utility model fully utilizes the heat of the car tail gas to get heat. The heating method has no influence on the normal work of the engine, and has no pollution on the air of the interior of the carriage.

Description

Automobile tail vapour waste heat heater

The utility model relates to automotive heatingn system.

At present, northern China highway passenger transportation bus heating is a kind of to be solely to fire the formula heater unit, though heating effect is good, needs fuel oil, wastes a large amount of energy; Though another kind is a way heating energy savings of utilizing water tank waste heat or water-circulating, heating effect is very poor; Also have a kind of eduction pipe is prolonged receive passenger vehicle inside, utilize the heating of tail vapour waste heat, though effect is better, existing increases the steam discharge resistance, reduces engine power, increases in the car many problems such as noise, and the danger of air in the tail vapour leakage pollution car is arranged.

That the purpose of this utility model is to provide is a kind of not only energy-conservation, but also the passenger vehicle heating installation of safe utilization automobile tail vapour waste heat.

The purpose of this utility model realizes by technical scheme shown in the drawings, it has a tail vapour connecting tube that connects the auto-exhaust pipe, the utility model has a heat-collecting box 10, heat-insulation layer 12 is arranged on the heat collecting tank, the heat-collecting box middle part is separated by dividing plate 8, lower part box is a heat storage box 4, be provided with heat transfer device 9 in the casing, heat transfer device top is radiator structure, the lower end places in the heat storage box by dividing plate, tail vapour connecting tube bifurcated backward is two pipelines, a pipeline extends in line pipeline 1 outward backward by heat collecting tank, another pipeline passes tank wall and inserts in the heat storage box, as heat-collecting box heat supply pipeline 2, at the opposite side of tank wall a heat-collecting box blow-off line is arranged, blow-off line is communicated with in line pipeline rear portion, front end in line pipeline and heat-collecting box heat supply pipeline is equipped with closedown of pipeline switch 3, in upper box one side of heat storage box the connection pipe 6 of a connection blower fan 5 is arranged, and in a relative side warm braw delivery piping 11 that can insert in the car body is arranged.

The utility model warm braw pipeline passes load carrying floor 7 and inserts in the original warm braw passage of passenger vehicle, as passenger vehicle

Do not have the warm braw passage, the warm braw passage can be set in the passenger vehicle case voluntarily, the utility model has made full use of the heat heating of automobile tail vapour, and heating system neither influences the normal operation of driving engine, does not pollute the air in the railway carriage again.The utility model can reduce passenger vehicle winter operation expense greatly, and energy savings has increased the economical operation benefit.During without heating, the switch on the heat supply pipeline can cut out, the tail vapour directly in line pipeline outside casing is discharged.The utility model is simple in structure, and is easy for installation, and cost is low, and noiselessness has no effect to the running power and the profile of automobile.

Accompanying drawing is the utility model structural representation.

Describe structure of the present utility model in detail below in conjunction with embodiment.

One, the heater that is used for motorcoach.The oad of heat-collecting box is: casing is high 600 millimeters, and is long 500 millimeters, wide 250 millimeters, casing is made by the A3 plate, and casing is divided into two-layer, and there is warm material the centre, heat pipe is an energy-saving high efficient heat tranfer device, and the high-efficiency heat conduction material is housed in the pipe of this heat transmitter, and top is fixed with fin, heat transmitter is high 450 millimeters, 21 heat transmitters are housed in the casing, and the dividing plate in the heat-collecting box is an iron plate, is welded in the casing, sealing fully between the last lower box is in case automobile tail vapour enters upper box.The power of the blower fan of configuration is 100 watts, and air quantity is 500 cubic meters per hour, and the switch on the pipeline adopts flange plate structure, and when closing, plate object of flange therebetween gets final product.Tail end in line pipeline is equipped with silencer.The utility model driving is after 30 minutes, and the temperature out of heater is 60 ℃.The utility model is fixed on the underframe of automobile.

Two, the heater that is used for microbus.Oad is: high 350 millimeters, and long 350 millimeters, wide 180 millimeters, 13 energy-saving high efficient heat tranfer devices that distribute in the casing, heat transmitter is high 300 millimeters.Allocating power is 60 watts a blower fan, and air quantity is 350 cubic meters per hour, and other structures and data are the same.
