At present, most of middle-size and small-size car amounts adopt the water heating type warm-air device heating, water heating type warm-air device utilizes the heat of engine cooling water more, the size of cal val directly is subjected to the impact of engine operating condition, cal val is less and limited by water temperature, and just works after only coolerstat is opened when water temperature is higher than 80 ℃.In recent years, fast development along with China's auto trade, the energy-saving and emission-reduction project of automobile receives increasing concern, the exhaust temperature of auto emission reaches as high as 600 ℃-700 ℃, the heat that tail gas is taken away accounts for 30% of oil inflame thermal output, and in northern cold season, often has the problem of heat supply deficiency in the middle-size and small-size vehicle car, for addressing this problem, someone has designed several device (patent No.s 200720010207.2 of utilizing engine tail gas waste-heat heating; 01237512.8), and these install the resistance of exhaust that has obviously increased driving engine after series winding accesses in freeing pipes, affected the serviceability of driving engine, and the H Exch volume in this class device are large, complex structure, thereby be not used widely.Although have in recent years the people that hot pipe technique is used on the heating automobile, the hot tube heat exchanger (patent No. 00259619.9 occurred; 95225773.4), effect is relatively good, but because cost compare is high, does not popularize in auto trade.
Summary of the invention
The utility model provides a kind of residual heat type heater, can solve in the existing automobile residual heat formula heater H Exch volume large, and inner structure is complicated, obviously increases the engine exhaust resistance, the technical matters of be difficult to dismantle, the deficiency such as ash disposal being brought.
The technical scheme that its technical matters that solves the utility model adopts is: utilize residual heat of tail gas of automobile auxiliary heating device, comprise H Exch, water pump, temperature booster, tail gas control cock, in the bleeder line behind the air inlet pipe of H Exch both sides, the freeing pipe access ternary catalyzing unit, the air inlet mouth of pipe is provided with the tail gas control cock, temperature booster is comprised of heater core and blower fan, and heater core is connected with the compensation bucket.
H Exch described in the utility model comprises air inlet pipe, freeing pipe, housing, single straight tube, end cap, the some exclusive fins of single straight tube outside uniform welding, and every row is provided with some little fins, even perforate on it, single straight tube inboard is provided with inner fin.
Single straight tube described in the utility model cooperates the adapting pipe joint, and adaptor union is provided with the refrigerant fluid switch.
All adopt the hermetically-sealed construction of asbestos seal ring between end cap described in the utility model and housing, end cap and the single straight tube.
The water heating type heating system of auxiliary heating device described in the utility model and driving engine shares a temperature booster.
The structure that the utility model adopts can reduce the volume of H Exch, when taking full advantage of engine tail gas waste-heat, the engine exhaust draught control in a rational scope, is guaranteed the normal operation of driving engine.Two end caps of H Exch are connected with its housing with bolt and nut, and convenient disassembly is convenient to remove the crock in the H Exch.Fin in the H Exch is divided into multistage, can reduce the het expansion of fin, has many apertures on the fin, can increase the disturbance of flue gas, improves the coefficient of heat transfer.The water heating type heating system of this auxiliary heating device and driving engine shares a temperature booster, has reduced cost.
