Abstract

The invention discloses a residual heating device and a control method thereof for exhaust of a car , comprising: a heat exchanger, which comprises a heat exchange tube for accommodating a heat conducting liquid; A heat exchange cavity is sleeved on the outside of the heat exchange tube, and one end of the heat exchange cavity is connected with a bus exhaust pipe; A radiator communicating with theheat exchange tube, a water tank heating system communicating with the radiator, an engine cooling cycle system communicating with the radiator, and an engine coolant capable of circulating heating between the radiator and the engine; A fan arranged on one side of the radiator for blowing hot air into the bus for heating; A controller is arranged between the heat exchanger and the radiator, and communicates with the water tank heating system and the engine cooling cycle system, The invention also provides the control method thereof for exhaust of the car.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a passenger car exhaust waste heat heating device and a control method thereof. Background technique [0002] Generally, the heating of small vehicles in winter mainly uses the heat of the engine coolant for heating, while the compartments of large passenger cars are relatively large and mostly use diesel engines, which have high thermal efficiency and the operating temperature of the engines is lower than that of gasoline engines. Not enough, it is necessary to additionally use independent heat sources burning gasoline, kerosene, diesel and other fuels for compartment heating. This method wastes more fuel, causing large passenger cars to consume more fuel in winter than in other seasons. [0003] At present, there is also a design of using engine exhaust for heating, which is realized by installing a heat exchanger between the engine and the muffler. After the heat is absorbed by the fr...
