Abstract
The utility model relates to a warm air device for an agricultural transport motor tricycle, which utilizes end gases of an engine to conduct heating and defrosting. The utility model is provided with a silencing heat exchanger which is arranged in an exhaust pipeline of the engine and has the functions of silencing, reduction of noise and heating cold air, a blower blows the cold air from an operator cabin into an air heating passage of an inner cavity of the silencing heat exchanger, and the cold air is heated by the high temperature end gases and delivered to the operator cabin so as to improve the driving condition in winter. The utility model has the advantages of good heating effect, safety and sanitation, energy saving and simple structure.
Description
The utility model relates to the vehicle cab heating device technology area that the waste gas that utilizes power plant comes heated air.
At present, though the three-wheeled farm transport vehicle of band operator cabin can improve the riving condition in winter to a certain extent, because cab structure is simple, heat-shielding performance is poor, so it is lower still to exist the winter driving room temperature, the problem that front windshield frosting difficulty is removed.The patent No. is 96218740.2 " agri-vehicle warm braw gloves " though utilize engine tail gas heat quantity that the heating of driver's hand is provided, because its temperature is low, air quantity is little, contains poisonous tail gas in the warm braw, thereby is difficult in practice promote the use of.
The purpose of this utility model provides a kind of waste heat heated air of engine exhaust of utilizing to improve the three-wheeled farm transport vehicle heater of operator cabin temperature.
The technical solution of the utility model is: it has a silencing heat exchanger that is installed on the engine exhaust pipeline, and this silencing heat exchanger can effectively be subdued exhaust sound, can utilize using waste heat from tail gas heats cold air again.The air heating passage is housed in the inner chamber of silencing heat exchanger.On the cold wind intake grill of silencing heat exchanger, be connected with cool air hose, be equipped with on the cool air hose cold wind is blasted blower fan in the silencing heat exchanger.Be connected with warm-air pipe on the hot blast exhaust outlet of silencing heat exchanger, three-way valve is housed on the warm-air pipe, two exhaust outlets of three-way valve are connected with the hot-blast spray nozzle that is placed in the operator cabin by airduct respectively.
The utlity model has following advantage: the one, make full use of engine tail gas heat quantity, save the energy; The 2nd, hot blast separates fully with tail gas, safety and sanitary; The 3rd, quick heating, temperature height, warm braw amount are big, can reach heating, defrosting requirement rapidly; The 4th, simple in structure, easy for installation, do not influence the power character and the Economy of motor, improved the driving environment in three-wheeled farm transport vehicle winter greatly.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structure principle chart of the present utility model, shows the annexation of its each several part;
Fig. 2 is the mounting point figure of the utility model on three-wheeled farm transport vehicle;
Fig. 3 is the sectional view of noise reduction heating device, shows its internal structure;
Fig. 4 is the A-A sectional view among Fig. 3.
In the embodiment that accompanying drawing provides, the utlity model has a silencing heat exchanger (3) that is installed on motor 10 gas exhaust pipings, this noise elimination heat exchanger 3 has cartridge type shell 14, the shell inner cavity center is equipped with front end and is connected the offgas duct 13 that the rear end has the plurality of rows pore with engine exhaust pipe, the air heating passage 12 that utilizes high-temperature tail gas heats cold air is housed in the cavity that offgas duct 13 and shell are 14, vertical dividing plate also is separated out warm braw chamber 15 and the cold wind chamber 16 that communicates with air heating passage 12 in the middle of inner chamber, corresponding to cold wind chamber 16 and 15 positions, warm braw chamber cold wind intake grill 4 and the hot blast exhaust outlet 5 that is fixed on the shell 14 arranged, shell 14 rear ends are connected with exhaust emission tube 11.On cold wind intake grill 4, be connected with the cool air hose 1 that leads in the operator cabin, be equipped with on the cool air hose 1 cool air in the operator cabin is blasted blower fan 2 in the air heating passage in the silencing heat exchanger 3.On the hot blast exhaust outlet 5 of silencing heat exchanger 3, be connected with the warm-air pipe 6 that leads to operator cabin, three-way valve 7 is housed on the warm-air pipe 6, two exhaust outlets of three-way valve are connected with hot-blast spray nozzle 9 by airduct 8 respectively, one of them hot-blast spray nozzle 9 directly is blown into hot blast in the operator cabin, another hot-blast spray nozzle 9 is fixed on and blows to front windshield on the instrument panel, is used for quickly defrosting.
