Abstract

The utility model relates to an inner-outer circulation heating and frost removing unit of vehicle. A wind collecting hood, a wind inducing joint of the wind collecting hood and a wind collecting box which are orderly connected are arranged on the radiator of the engine. The wind collecting box inlet is provided with a wind quantity control valve and the front end is provided with a windshield defrosting opening. The front end of the inner circulation pipeline which passes through the vehicle is connected with the inner circulation wind box by the valve. The device guides the hot wind of the water tank of the automobile engine into the carriage through the wind collecting hood. The hot wind enters the circulation pipeline from the tail of the carriage. The hot wind returns to the wind collecting hood and then enters the next circulation. The inner-outer circulation heating and frost removing unit of vehicle solves the problems that the heater of the existing various passenger cars wastes the energy and the wind temperature, the wind speed and the wind quality do not reach the national standard and the warming effect is poor.

Description

Internal and external circulation type carriage heating defroster device

The utility model relates to the heating defroster device of vehicle, particularly heated air circulation type heating defroster device.

At present, it is multiple that the Passenger Cars in China and Abroad heating system mainly contains directly-heated type, stand alone type, engine cooling water circulation type, electrothermic type, fan type etc., more than these devices all exist at aspects such as consumes energy, hot blast quality, safetys problem and cost height, complex process, maintenance guarantee difficulty big, make difficulty be installed.In order to address these problems, people have done multiple effort, the technology that one key name is called " heating system using exhaust heat of cooling water expansion tank post bake " is disclosed for No. 88210592.2 as Chinese patent, be applicable in the front windshield glass defrosting of various vehicles and the compartment and warm oneself, by driving engine, engine water jacket, water pump, radiator tank, the noise silencer water jacket, the freeing pipe water jacket is formed, it is big to have dissipating area, transfer of heat is abundant, blower fan temperature out height, advantages such as heater unit long service life, the deficiency that exists is to adopt to add motor, the waste electric energy, the cost height, complex structure, wind of poor quality, and not being suitable for long-distance bus, application surface is narrow.

Task of the present utility model is: design the high internal and external circulation type carriage heating device of a kind of heat efficiency.

Task of the present utility model realizes as follows: internal and external circulation type carriage heating device is to have engine radiator, on the passenger vehicle of engine blower, be installed on the engine radiator top wind-collecting cover 1 is arranged, wind-collecting cover air-vent joint is equipped with in wind-collecting cover 1 outlet, be provided with volume control damper 2 in it, being connected with the wind-collecting cover Air joint is an air collecting box, the air collecting box inlet has volume control damper door 7, front end has windscreen defroster 9, article one, it is barrel-shaped that the internal recycle pipeline 13 that runs through the front and back of car is shaped as supreme cylinder of going to the bottom, front end links to each other with interior circulation bellows 6 by valve 8, be provided with the inner circulating air inlet at the railway carriage afterbody, in interior circulation bellows, be provided with recur damper.

The utility model is owing to be to be blown in the car after utilizing engine blower that fresh air outside air in the car or the car is heated by engine water tank, need not to increase blower unit, not power consumption, oil and other energy, periodical duty in adopting under the low situation of temperature can reach satisfied heating defrosting effect; Can adopt outer circulation when temperature is high, the fresh air that can enrich in the car can make the interior air themperature of car suitable again.

Fig. 5 is the A-A cutaway view of Fig. 2.

A most preferred embodiment of the present utility model, as figure, internal and external circulation type carriage heating device is to have driving engine 17, engine radiator 11, be installed on the engine radiator top on the passenger vehicle of engine blower 14 wind-collecting cover 1 is arranged, in the wind-collecting cover outlet wind-collecting cover Air joint 3 is housed, be provided with volume control damper 2 in it, being connected with the wind-collecting cover joint is an air collecting box 4, the air collecting box inlet has volume control damper door 7, its front end has windscreen defroster 9, article one, the internal recycle pipeline 13 that runs through the front and back of car is fixed on the railway carriage 18 as shown in Figure 2, internal recycle pipeline 13 to be shaped as supreme cylinder of going to the bottom barrel-shaped, front end links to each other with interior circulation bellows 6 by valve 8, be provided with inner circulating air inlet 16 at the railway carriage afterbody, in interior circulation bellows 6, be provided with recur damper 12.

1., the outer circulation working process its working process is:: the anterior air of passenger vehicle enters engine radiator 11 by louver 5, wind-warm syndrome is improved, by engine blower 14 wind is sent into wind-collecting cover 1, exhaust door 2 is closed, wind enters compartment or front windshield defroster 9 by 7 controls of volume control damper door, and formation I, II two lines enter interior heating; 2., interior periodical duty process: when interior needs strong heating, can use interior periodical duty, cold air enters internal recycle pipeline by afterbody inner circulating tube road junction, compartment 16 in the compartment, direction along internal recycle pipeline III enters interior circulation valve 8 to water tank 11 front portions, louver 5 is in closed condition before this moment, wind is sent in the wind-collecting cover 1 by fan 14 through water tank 11, this moment, valve for air exhaust 2 was closed, wind is by in the volume control damper door 7 guiding compartments or front windshield defroster 9, wind forms I and II route internal recycle pipeline 16 after the compartment enters by front windshield defrosting back, and the air in the compartment constantly circulates and makes the intensification of air staged in the middle of bus driving like this.Higher when compartment air temperature, when not needing heating, valve for air exhaust 2 is opened, the air in the wind-collecting cover 1 is just entered by the III route and leads to the outside, compartment in the car bonnet 15.

Claims

1, a kind of internal and external circulation type carriage heating defroster device, it comprises driving engine, engine radiator, it is characterized in that: being installed on the engine radiator top has wind-collecting cover, the wind-collecting cover Air joint is equipped with in the wind-collecting cover outlet, be provided with volume control damper in it, being connected with the wind-collecting cover Air joint is an air collecting box, the air collecting box inlet has the volume control damper door, front end has the windscreen defroster, article one, the front end of internal recycle pipeline that runs through the front and back of car links to each other with interior circulation bellows by valve, be provided with the inner circulating air inlet at the railway carriage afterbody, in interior circulation bellows, be provided with recur damper.
