Abstract
An automobile exhaust gas afterheat heater unit arranged with an auxiliary heater belongs to the technology field of heat exchange, and is composed mainly of an afterheat interchanger, an inlet pipe, an exhaust pipe, a radiator and a by-pass pipe. The auxiliary heater is arranged outside the afterheat interchanger; the auxiliary heater is provided with a hot gas way; a heat exchange pipe is arranged in the afterheat interchanger. When the afterheat from the exhaust gas is not enough to heat the vehicle, the auxiliary heater can be opened, and then the hot gas can get into the heat exchange pipe through the hot gas way to heat the water in the heat exchanger and increase heating value from the radiator. The utility model has the advantages of simple construction, convenient operation, small scale, light weight and high efficiency of heat exchange.
Description
Technical field:
The utility model belongs to technical field of heat exchange, is a kind of heater unit that utilizes the automotive exharst gas residual heat heating.
Background technology:
At present, utilize the heater unit of automotive exharst gas residual heat heating mainly to constitute by afterheat heat exchanger, air inlet pipe, freeing pipe, radiator, bypass pipe, at air inlet pipe and bypass pipe junction pipeline valve is arranged, adjusting valve at ordinary times makes air inlet pipe be communicated with bypass pipe, waste gas is discharged by air inlet pipe, bypass pipe, freeing pipe, when needing to heat in the car body, adjusting valve makes air inlet pipe connect afterheat heat exchanger, waste gas is discharged by air inlet pipe, afterheat heat exchanger, freeing pipe, waste gas is with the heating of the water in the afterheat heat exchanger, by the radiator heat supply.Northern area cold in winter only often can not reach temperature required by in the automotive exharst gas residual heat heating car.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of automotive exharst gas waste heat heater unit that can effectively vehicle interior temperature be heated to required temperature.
The scheme of the utility model technical solution problem is in the outside of afterheat heat exchanger auxiliary heater to be housed, hot gas path is arranged on the auxiliary heater, fuel atomizer and blower fan are equipped with in the outer end of hot gas path, the gas nozzle that leads to hot gas path is housed on the afterheat heat exchanger, heat-exchange tube is housed in afterheat heat exchanger, heat-exchange tube one end connects the inner of hot gas path, and the other end is connected with the auxiliary exhaust pipe, and the auxiliary exhaust pipe is contained in the afterheat heat exchanger outside.Generally speaking, when needing to warm oneself in the car, heat by waste heat, when the waste gas residual heat that provides can not satisfy in the car required heat, open auxiliary heater, make hot gas enter heat-exchange tube and further heat water in the afterheat heat exchanger, increase distributing of radiator heat by hot gas path.
For easy to operate, improve degree of automation, between air inlet pipe and bypass pipe, control cock is housed, temperature sensor is housed on the afterheat heat exchanger, temperature sensor is connected with controller, and controller connects control cock and auxiliary heater respectively.When temperature was low, controller started auxiliary heater, supplementary heating, and when temperature was high, controller commutated control cock, closed being connected of air inlet pipe and afterheat heat exchanger, made air inlet pipe and bypass pipe conducting, and waste gas is directly discharged by bypass pipe.
The utility model is simple in structure, and easy to operate, flexible, volume is little, and is in light weight, the heat exchange efficiency height.
Description of drawings:
Accompanying drawing is the utility model part sectional view.
The specific embodiment:
The utility model is by afterheat heat exchanger 1, air inlet pipe 2, freeing pipe 3, radiator 4, bypass pipe 5 constitutes, in the outside of afterheat heat exchanger 1 auxiliary heater 7 is housed, hot gas path 11 is arranged on the auxiliary heater 7, fuel atomizer 9 and blower fan 10 are equipped with in the outer end of hot gas path 11, the gas nozzle 8 that leads to hot gas path 11 is housed on the afterheat heat exchanger 1, heat-exchange tube 12 is housed in afterheat heat exchanger 1, heat-exchange tube 12 1 ends connect the inner of hot gas path 11, the other end is connected with auxiliary exhaust pipe 13, auxiliary exhaust pipe 13 is contained in afterheat heat exchanger 1 outside, between air inlet pipe 2 and bypass pipe 5, control cock 6 is housed, temperature sensor 14 is housed on the afterheat heat exchanger 1, temperature sensor 14 is connected with controller 15, and controller 15 connects control cock 6 and auxiliary heater 7 respectively.
