Abstract

The utility model relates to a waste heat switching device for vehicle exhaust gas. The utility model is provided with a cylindrical heat exchanging cavity in which more than 6 roots of corrugated pipes are fixed. The heads and the ends of the corrugated pipes which are arranged at the same one side are respectively communicated; the heads and the ends of the corrugated pipes which are arranged at the same other side are respectively communicated. The corrugated pipes which are arranged at the same one side and the corrugated pipes which are arranged at the same other side are communicated to form a cavity of which one end is provided with an air inlet and the other end is provided with a warm air outlet. An exhaust gas passageway is arranged at the external side of the wall of the corrugated pipes in the cavity. One end of the cavity is provided with an exhaust gas inlet which is communicated with an exhaust gas exhausting chamber; the other end is provided with an exhaust gas outlet which is communicated with the external side of the vehicle through a silencer. Through being filtrated and heated, air in the vehicle can be input into the inside of the vehicle by the utility model to form a multiplier-shaped heating method. Having the advantages of high heat energy conversion rate and no heating cost. The utility model can realize exchange supply in high and low size oil. The utility model can solve the difficult problem that diesel oil in low number can not be used in cold areas in winter. Being a heating device, the utility model can be widely used for passenger vehicles in large and middle sizes and camions.

Description

Automobile tail vapour residual heat conversion device

The utility model relates to the heat installation of the heating installation of vehicle, particularly truck, large and medium-sized passenger vehicle and autotruck.

Heating installation in the general car of existing automobile has hot-water heating warm braw, diesel oil warm braw, in luxury sedan-chair, the passenger vehicle conditioning unit is housed and warms oneself.These heating arrangements are installed on the car needs consumes energy, and cost is also higher, so always can not heating service owing to there not be suitable heating installation in the vehicle car such as motor omnibus.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of higher automobile tail vapour residual heat conversion device that heats of adopting thermal behavior that has in car.

Task of the present utility model realizes as follows: it has a barrel-shaped heat exchanging chamber body of cylinder automobile tail vapour residual heat conversion device, its internal fixation has 6 above bellowss, the bellows that two ends are connected respectively with the opposite side two ends are communicated with respectively that is positioned at the bellows of homonymy is connected, and to constitute a side be admission port, opposite side is a heat outlet, the wall of cavity inner corrugated pipe is outward an exhaust gas channel, one end of cavity is that gas inlet is connected with the tail gas discharge chamber, the other end is that the tail gas outlet is interlinked to the outside through silencer and car, and the admission port of bellows is connected with the valve that links to each other successively, prerotator and air filter; Three-way valve, equal tracheae are housed on the hot gas exhaust tube that the heat outlet of bellows is connected to.

The utility model is owing to adopt bellows to change the radiation environment of tail vapour heat energy effectively as the heat-exchanger rig of tail gas, created the condition of bellows group absorption heat energy, air in the car has so just been constituted the double type type of heating through heating to import then after filtering in the car, the high no heating cost of thermal power transfer degree of utilization not only, and have simple in structure, do not take interior space, keep advantages such as the interior air of car is fresh; Owing to adopt this device to carry out the controlled heating arrangement that makes the low-grade oil case of heating with enough temperature heating fuel oil and number reach the temperature of its adaptation according to oil to the diesel-powered vehicle fuel transfer system, realized that high-low signal bunker oil changes a supply process, solved extremely frigid zones and can not use a difficult problem of hanging down number diesel oil winter.

A most preferred embodiment of the present utility model, as figure, the residual heat of tail gas of automobile transfer device comprises a cylindrical heat exchange cavity 1, its internal fixation has 6 above bellowss 2, the bellows number can be 6,8,10, present embodiment adopts the six roots of sensation, the bellows that three two ends are connected respectively with the opposite side two ends are communicated with respectively that six roots of sensation bellows is positioned at a side is connected, and to constitute a side be that admission port 3 opposite sides are heat outlet 4, be provided with at the air inlet/outlet end place of cavity and divide cross-sectional periphery equally be divided into the air inlet/outlet end two dividing

plates

7,8, cavity is divided into the turnover air cavity herein, wherein, the bellows group mouth of admission port end communicates with inlet chamber, and the bellows group mouth of air extractor duct end communicates with outlet chamber.The wall space outerpace of cavity inner corrugated pipe is an exhaust gas channel, one end of cavity is a gas inlet 5, be connected with the automobile engine tail gas discharge chamber, the other end is tail gas outlet 6, is interlinked to the outside through silencer and car, present embodiment adopts one-level formula heat exchanger, heating space actual needs according to various vehicles can adopt the combination of secondary formula heat exchanger, and promptly two heat exchanger cavity are in series as shown in Figure 6, or adopts three grades of formula heat exchanger combinations, promptly three heat exchanger cavity are in series, as shown in Figure 7.The characteristics of this structure are that the heat-exchanger rig of larger volume can be installed in less space according to the practical structures of various different automobile types.The admission port end of bellows onboard is installed is connected with the three-way valve 22 that links to each other successively, its effect is: because of this summer in equipment winter standing, during Long-time Shut-down for reduce heat conduction and atmosphere connect with.Prerotator 21 and air filter 9, on the exhaust tube of the heat outlet end of bellows three-way valve 10 is housed, equal tracheae 12 is housed on one arm 11, manual draw bar formula through way valve 13 is housed on another arm, the copper pipe group 14 of the straight-through low-grade oil case of its outlet realizes controlled the heating of diesel-powered vehicle fuel transfer system.

The working process of this device is: tail gas enters heat-exchanger rig through inlet port, air is through air filter in the car, prerotator enters the bellows group and does multi-stage rotary therein and back and forth heats, air after the heating is through the hot gas exhaust tube, manual triple valve, exhaust outlet enters equal tracheae and is dispersed into heating in the car, controlled the heating of low number diesel oil fuel transfer system 15 is by the hot gas exhaust tube, manual triple valve, manual rod-pulling type through way valve is done out, the heat supply of closing or adapting to is separated stream to supply with the enough temperature heating fuel oil of open circuit copper pipe group in the low-grade oil case, be as the criterion the supply process that adjusting yoke formula two position three-way valve realization high-low signal bunker oil is replaced with its suitable temperature according to oily number.16 is the height fuel tank among the figure, and 17 is the height delivery line, and 18 is the two-bit triplet change-over valve, and 19 is high pressure pump, and 20 is heat indicator.
