The tail gas heat exchanger has the advantage that the waste gas conversion rate and the waste gas heat utilization rate are effectively improved through the heat exchanger.
Description
Technical field
The present invention relates to a heat exchanger apparatus, relate in particular to a kind of heat exchanger apparatus that adds hot water with vehicle exhaust.
Background technology
Nowadays, there is increasing choose self driving on and off duty, still; People notice in steering vehicle; Automobile approximately has only 1/3rd to be used to promote vehicle body and to advance when with combustion engine gasoline being produced power, have in addition three/second with the used heat form by radiation with emit.In order to prevent too much discharging waste, prior art is installed an interlayer at the exhaust pipe place, the logical hot waste gas of pipe in being enclosed within; Logical cooling water expansion tank in interlayer, after cooling water expansion tank absorbed the tail gas heat quantity intensification, valve can be opened hot water automatically and lead in the compartment through pipe special; To the compartment heating, the energy consumption that can save former air-conditioning in winter, but because this heat exchanger is to adopt traditional single-point heat balance method of; So conversion ratio is not high enough, the blow down gas temperature is still higher.
Summary of the invention
The purpose of a kind of tail gas heat exchanger of the present invention has been to provide a kind of heat exchanger with the reverse convective heat exchange of multiple spot, improves conversion ratio effectively, increases the degree of utilization of waste-gas heat.
To achieve these goals, the technical scheme taked of the present invention is:
A kind of tail gas heat exchanger, wherein, the side's of comprising copper pipe, spiral tube, two end sockets are provided with said spiral tube in said side's copper pipe, and said end socket is provided with a water outlet and an air extractor duct, the two-port of two the end socket side of covering copper pipes; The outside face of side's copper pipe is pasted with a cooling piece, and said cooling piece is provided with electrode wires; The outer end of cooling piece is pasted with a radiating gill.
Further, the cross sectional shape of said side's copper pipe is a square.
Further, the two ends of said spiral tube are connected to the water outlet of two said end sockets.
Further, the two ends of said spiral tube are set to rectilinear tubes.
Further, the material of said spiral tube is a red copper.
The present invention is owing to adopted above-mentioned technology, and the good effect that makes it to have is:
(1) improved the conversion ratio of waste gas effectively through the mechanism of multiple spot reverse heat-exchange.
(2) improved the degree of utilization of waste-gas heat effectively.
Description of drawings
Fig. 1 is a kind of scheme drawing of tail gas heat exchanger.
The specific embodiment
Provide the specific embodiment of a kind of tail gas heat exchanger of the present invention below in conjunction with accompanying drawing.
Fig. 1 is a kind of scheme drawing of tail gas heat exchanger, a kind of tail gas heat exchanger of the present invention, and the side's of comprising copper pipe 6, spiral tube 1, two end sockets 5, the material of square copper pipe 6 is the red copper material, to play permeability of heat preferably.The centre of side's copper pipe 6 is provided with a spiral tube 1, and the material of spiral tube 1 is the red copper material, plays to add good permeability of heat.The two ends of spiral tube 1 are set to rectilinear tubes, and promptly the two ends of spiral tube 1 are straightened.The end face of two end sockets 5 is provided with a water outlet and an air extractor duct, and two end sockets 5 are respectively applied for the two-port of covering side's copper pipe 6.The outside face of side's copper pipe 6 is pasted with a cooling piece 4, and the outer end of cooling piece 4 is pasted with a radiating gill 3.
Wherein, the cross sectional shape of square copper pipe 6 is a square, to play the square that is shaped as that spiral tube 1, two end socket 5 conveniently is set, to play the two-port that can seal the side's of covering copper pipe 6.Cooling piece 4 is provided with four, and four cooling pieces 4 be shaped as oblong, the outside face of the side's of covering copper pipe 6 fully, four cooling pieces 4 be four surfaces through the heat-conducting glue side of sticking on copper pipe 6 respectively, to play the effect of refrigeration.Radiating gill 3 is provided with four, and the cross sectional shape of four radiating gills 3 is set to oblong, and an end face of four radiating gills 3 sticks on the end face of four cooling pieces 4 through heat-conducting glue respectively fully, and guarantees the radiating groove side of the deviating from copper pipe 6 of radiating gill 3.
Wherein, the medial end portions branch of spiral tube 1 is set to helix, so that the water through spiral tube 1 spiral part can be contacted with spiral tube 1 outer gas better; The two ends of spiral tube 1 are set to rectilinear tubes, and promptly the stretching part in the two ends of spiral tube 1 is outwards pulled out through the water outlet of two end sockets 5 respectively, and the spiral tube 1 in the square copper pipe 6 is a spiral part
Wherein, cooling piece 4 is provided with electrode wires 41, and the voltage of electrode wires 41 is set to 20V, so that make an end heating of cooling piece 4, the other end turns cold.
A kind of tail gas heat exchanger of the present invention is arranged on automobile tail gas pipe with device, and air extractor duct inlet side 21 is connected in offgas duct.With the inside of hot exhaust gas, go out end 22 from air extractor duct and discharge through air extractor duct inlet side 21 entering side's copper pipes 6.With cooling water expansion tank 11 feedings from the water outlet inlet side, the inside of the side's of pouring into copper pipe 6 goes out end 12 from water outlet and flows out, and the water that flows out is linked in the compartment.During use, tail gas is 21 feedings from the air extractor duct inlet side, cold 11 feedings from the water outlet inlet side of anhydrating; Tail gas in the spiral tube 1 cools off, and cooled tail gas goes out end 22 from air extractor duct discharges, and the cooling water expansion tank of heating goes out the end 12 to flow out from water outlet; And 100 ℃ of drain water Wen Gaoda; Through pipe special current are led in the compartment, to compartment heating, the energy consumption that can save air-conditioning in winter.Electrode wires 41 is switched on, make an end heating of cooling piece 4, water is heated, the other end turns cold, and outwards dispels the heat through radiating gill 3.
In sum, use a kind of tail gas heat exchanger of the present invention, effectively improved the conversion ratio of waste gas and the degree of utilization of waste-gas heat through heat-exchanger rig.
