Concrete, the described pars intermedia of described H Exch can be formed by multiple steel-pipe weldings, its concrete shape is similar to honeycomb coaly, described inside exhaust pipe is communicated with the exhaust pipe of engine and described silencer, tail gas enters described silencer from the described exhaust pipe of engine through described inside exhaust pipe, finally discharges.Between described inside exhaust pipe outside and heat exchanger shell, there is refrigerant fluid, in the time of the described inside exhaust pipe of high-temperature tail gas process, heat its outside refrigerant fluid, the refrigerant fluid of heat enters engine sump tank temperature booster and radiator by described water pump pressurization through valve, for driving engine and operator's compartment heating, cooled refrigerant fluid flows back to described H Exch by water return outlet again, has well utilized the heat of tail gas, owing to being provided with multiple inside exhaust pipes, exhaust emissions back pressure is very low simultaneously.

Further, the preferred amount of the described inside exhaust pipe of described pars intermedia is 4.

Preferably, the diameter of described inside exhaust pipe equates with the diameter D1 of described connecting portion small end, and the diameter of described pars intermedia is the D1 of five times, and the bell-mouthed height H of described connecting portion is the D1 of three times.

Preferably, described connecting portion is connected with the described exhaust pipe of engine and described silencer by tie bolt.

The beneficial effects of the utility model are: utilize engine high-temperature tail gas by H Exch, refrigerant fluid to be heated, utilize water pump by the cooling-liquid cycle in H Exch, by radiator, heat is offered to automobile cab and automobile engine oil pan, improve operator's compartment temperature, chaufeur can be driven a car under normal temperature, avoid because operator's compartment temperature is too low, driver's operation is stiff, it is slow to reflect, existing traffic accident; Can make on the other hand engine oil pan temperature improve simultaneously, be conducive to engine starting and lubricated in winter, can close this device summer, recovers the normal work system of automobile.
