Description
The utility model relates to a kind of automobile wind screen defrosting heat supply machine that utilizes the waste hot gas of auto emission for thermal source.
The water heating type device is generally all adopted in the heat supply of automobile defrosting at present, promptly utilizes the radiator of car engine heat to reach the purpose that heat supply defrosts through the circulating device substracted heat, but.Its heating defrosting effect is undesirable.And the outer circulation hot-air heater of the dim formula of employing gas, shortcomings such as device is big because it exists, complex structure, heat is lost greatly, heat efficiency is low are not extensively promoted the use of.
The purpose of this utility model is the problem at above-mentioned existence, has proposed a kind of waste-gas heat of auto emission, windscreen for vehicle defrosting heat supply machine that structure is simple, heat efficiency is high, the heat supply defrosting effect is good, nothing is given up toxic gas leakage of making full use of.
The technical solution of the utility model is as follows:
The utility model is made of wind collection scoop, heat exchange chamber, air chamber, air valve, wind conveying pipe, defroster etc.Described wind collection scoop is the horn-like rear side that places cooling fan of engine, heat exchange chamber is a closed chamber, the air pipe (sheet) of some spaces is housed in it, be the mobile crack of waste hot gas between above-mentioned air pipe (sheet), and respectively be loaded on heat exchange chamber on waste hot gas enter the pipe and exhaust tube be connected, above-mentioned waste hot gas enters pipe and is connected with the vehicle engine exhaust gas exhaust tube, the waste hot gas exhaust tube then is connected with the noise silencer of automobile, air pipe (sheet) end in the above-mentioned heat exchange chamber is connected with wind collection scoop, its other end then is connected with air chamber, the top of this air chamber is a heat outputting charge air size adjustment air valve, and this air valve is then with the hot gas delivery pipe and be attached thereto defroster logical and that be positioned at the Windshield below and link to each other.
Air pipe (sheet) in the above-mentioned heat exchange chamber is fan-shaped tubulose or fan-shaped sheet.
Be provided with a direct discharge side of hot air on the above-mentioned air valve.
Principle of work of the present utility model is such:
When behind the engine starting or vehicle when advancing, engine cooling is that the moving air that produces of fan and the vehicle wind head-on of advancing enters the air pipe (sheet) of heat exchange chamber from wind collection scoop, and the high hot waste gas that the exhaust pipe of engine is discharged enters pipe along waste hot gas and enters waste hot gas in the heat exchange chamber crack of flowing.Two kinds of different temperatures and not the gas that mixes of direct contact utilize metal-air pipe (sheet) wall to carry out interchange of heat, waste hot gas flows out heat exchange chamber through the waste hot gas exhaust tube then, enters the automotive muffler processing of eliminating the noise then.And flow to air chamber behind the atmosphere temperature rising in air pipe (sheet), spray from defroster through air valve and wind conveying pipe, for wind screen defrosting be the interior space heat supply.According to the needs of temperature, the size of scalable air valve if need not heat up, then can place air valve direct discharge side position in car, can directly hot air be arranged in atmosphere.
The utility model has made full use of the waste hot gas of automobile, has saved the energy, the heating efficiency height, the heat supply defrosting effect is good, this device adopts the design in " a pipeful of two chambeies ", has avoided operational hot air to mix with the mutual of waste hot gas, thereby useless accident to leak the poison gas can not take place.Simultaneously, apparatus structure is simple, and is compact to design, safe and reliable, easy to maintenance, is a kind of desirable automobile defrosting heating plant.
Among Fig. 1 the utility model structural representation figure: 1 cooling fan, 2 wind collection scoop 3 heat exchange chambers, 4 air pipes (sheet), 5 waste hot gas enter the mobile crack of pipe 6 waste hot gas 7 waste hot gas exhaust tubes, 8 air chambers, 9 one control air valve, 10 direct discharge side 11 wind conveying pipes 12 defroster
Further specified below in conjunction with embodiment:
Heat exchange chamber of the present utility model (3) selects for use low-carbon steel material to make, crooked curved being welded in the heat exchange chamber of corrosion-resistant steel air pipe (4), formed the mobile crack (6) of fully enclosed waste hot gas between the air tube and tube in the chamber, wind collection scoop (2) is shaped to that bell mouth shape is riveted on the heat exchange chamber and communicates with above-mentioned air pipe, and be positioned at the rear positions of automobile engine cooling fan (1), and air chamber (8) is riveted on the air mouth of pipe of another port in the heat exchange chamber too, and wind collection scoop and air chamber all adopt low-carbon steel material to make.On heat exchange chamber, also be welded with respectively the carbon steel pipe material and the waste hot gas that is connected with above-mentioned mobile crack (6) enter pipe (5) and waste hot gas exhaust tube (7), the above-mentioned pipe that enters communicates with the driving engine exhaust tube, above-mentioned exhaust tube then communicates with the noise silencer of automobile, it above above-mentioned air chamber the size that one control air valve (9) is used for regulating control hot gas flow, also be provided with the direct discharge orifice of a hot gas (10) on this valve, directly hot gas discharged in atmosphere when being used in car, not needing hot gas.What be connected with air valve is the outside wind conveying pipe (11) that adopts resistant to elevated temperatures India rubber tube to make, and this wind conveying pipe then communicates with the defroster (12) that is positioned at the Windshield below, and the hot blast that defroster is sent can also can be used for heating in the car for wind screen defrosting.
