Vortex type automobile exhaust heating device and its control method

Abstract

A vortex type automobile exhaust heating device comprises an engine exhaust pipe, a muffler, a heat exchanger and a water pump shell. A sealing cavity filled with cooling liquid is arranged outside the heat exchanger, a vortex generator is arranged on the inner side of the sealing cavity through vortex generator fixing rods, water pipe connectors are arranged on the sealing cavity, a water pump drive shaft with a turbine blade in the middle is arranged in the water pump shell, and magnetic bearing bearings are arranged at the two ends of the water pump drive shaft. The vortex type automobile exhaust heating device further comprises a water pump. The inlet of the water pump is connected with one water pipe connector through a water pipe, the outlet of the water pump is connected with an oil pan heater, a flow valve, a radiator and the other water pipe connector through the water pipe, and the flow valve is connected with an electromagnetic valve controlled by a temperature control module. The vortex type automobile exhaust heating device comprises a temperature sensor connected with the temperature control module. Waste heat of engine high temperature tail gas is provided for a cab through the heat exchanger, the water pump, the flow valve, the radiator and other components, and the purpose that waste heat is utilized is achieved. The vortex type automobile exhaust heating device is simple in structure, convenient to operate, safe and good in heating effect, and saves energy.

Description

technical field [0001] The invention relates to a device for recovering and utilizing the heat of automobile exhaust and a control method thereof, in particular to a vortex type automobile engine exhaust heating device and a control method thereof, belonging to the technical field of automobiles.

[0002] With the continuous increase of the number of automobiles in our country, automobiles have spread all over the country, and there are footprints of automobiles in towns and villages in various regions. With the increase in the use of automobiles, some problems in the use of automobiles are also constantly reflected, such as The problem of car warmth in winter is particularly prominent, especially in Northeast China, where the average winter temperature is about minus 30°C. When the car is driven at minus 30°C, the temperature of the cab is low. Drivers and passengers feel uncomfortable in this environment for a long time. It is very cold, the driver’s body will be stiff when driving in this environment for a long time, the operation will be inflexible, and traffic accidents will easily occur. It is thicker and harder to start. Due to the thick oil and poor lubrication, it will accelerate the wear of the engine cylinder and shorten the service life of the engine. Based on the above reasons, car heating devices and engine heating pots are used, but the current heating device Generally, the cooling water of the engine body is used 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, and the heating pot usually uses gasoline to heat the engine. This method is not energy-saving enough. 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.
