Automatic adjustment type automobile exhaust heating device and control method thereof

Abstract

The invention discloses an automatic adjustment type automobile exhaust heating device and a control method thereof. The automatic adjustment type automobile exhaust heating device comprises an engine exhaust pipe, a muffler, a heat exchanger, a water pump shell, a water pump in transmission connection with a water pump drive shaft and a temperature sensor connected with a control module, wherein a sealing cavity is arranged at the outside of the heat exchanger; two water pipe joints are arranged on the sealing cavity; the water pump shell is internally provided with the water pump drive shaft having turbine blades at the middle part; a magnetic bearing is arranged between the two ends of the water pump drive shaft and the water pump shell; the inlet of the water pump is connected with one water pipe joint through a water pipe; the outlet of the water pump is connected with a flow valve, a radiator and the other water pipe joint sequentially through the water pipe to form a loop; the flow valve is connected with an electromagnetic valve which is controlled by the control module. According to the automatic adjustment type automobile exhaust heating device, the afterheat of the high-temperature exhaust of the engine is provided to an automobile cab through the heat exchanger, the water pump, the flow valve, the radiator and the like, so that the purpose of afterheat utilization is realized. The automatic adjustment type automobile exhaust heating device is simple in structure, exact in control, convenient to operate, energy-saving and safe, and good in heating effect.

Description

technical field [0001] The invention relates to a device for recovering and utilizing the heat of automobile tail gas and a control method thereof, in particular to an automatic adjustment type car engine tail gas heating device and a control method thereof, belonging to the technical field of cars. Background technique [0002] During the use of the car in winter, the most important problem is the heat preservation of the car. Since the temperature in winter is more than 20 degrees below zero, the temperature of the car cab is particularly important. The heat preservation of the modern car cab is to provide the heat of the engine to the car through the radiator. In the cab, the engine heating system cannot effectively provide heat for the cab. In winter, the engine temperature is low, and the driver and passengers are very cold. The driver is not flexible when driving the car for a long time, and traffic accidents often occur, especially in the northeast region. In winter, ...

Problems solved by technology

[0002] During the use of the car in winter, the main problem is the heat preservation of the car. Since the temperature in winter is more than 20 degrees below zero, the temperature of the car cab is particularly important. The heat preservation of the modern car cab is to provide the heat of the engine to the car through the radiator. In the cab, the engine heating system cannot effectively provide heat for the cab. In winter, the engine temperature is low, and the driver and passengers are very cold. The driver is not flexible when driving the car for a long time, and traffic accidents often occur, especially in the Northeast region. In winter, the climate is cold, and the car is parked outside at minus 30°C. A high-heat heating device is needed to heat the cab of the car. However, the current heating device generally uses the cooling water of the engine body as the heat source. When the car is in a low temperature environment, The cooling water temperature of the engine is low, and the heat provided is limited. There are also some heating devices that use automobile exhaust as cab heating, but their structures and controls are complex and have a single function.
