Vehicle and its temperature regulation system and temperature regulation method

Abstract

The invention discloses a vehicle as well as a temperature adjusting system and a temperature adjusting method thereof. The temperature adjusting system comprises a main air passage module, an assistant air passage module, and an engine tail gas residual heat utilization module, wherein the main air passage module comprises a main air passage inlet which can be opened and closed; when the main air passage inlet is opened, a power module of the vehicle communicates with atmosphere through the main air passage inlet; when the main air passage inlet is closed, the communication between the power module and the atmosphere through the main air passage inlet is cut off; the assistant air passage module comprises assistant air passage inlets and blowing devices, wherein the assistant air passage inlets communicate with the power module, inlets of the blowing devices communicate with the atmosphere, and outlets of the blowing devices communicate with the assistant air passage inlets; the engine tail gas residual heat utilization module comprises a pumping device for transporting a heat exchange working substance, a heat exchanger utilizing engine tail gas of the vehicle to heat the heat exchange working substance, and a heater assembly for releasing heat absorbed by the heat exchange working substance. According to the vehicle as well as the temperature adjusting system and the temperature adjusting method thereof disclosed by the invention, in the temperature adjusting process, engine loads are reduced, and the consumption of fuel oil is reduced.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle and its temperature regulation system and temperature regulation method. Background technique [0002] The vehicle's engine coolant is required to work within a certain operating temperature range so that the engine can run efficiently and avoid malfunctions. Too high or too low coolant temperature will cause engine damage. [0003] Taking road sweepers as an example, in the existing cooling systems for road sweepers, a fan-radiator cooling system consisting of a cooling fan fixed to the engine and an engine radiator is mostly used to regulate the temperature of the vehicle. When the ambient temperature is high, the fan-radiator cooling system will have insufficient heat dissipation capacity, which will cause the cylinder head, piston and other parts of the engine to be easily damaged due to heat, and the engine's air intake will be insufficient and the power will drop. When th...

Problems solved by technology

[0006] When the ambient temperature is high, the system can only cool down by increasing the fan speed, which makes the engine load higher and fuel consumption larger;

[0007] When the ambient temperature is low, an independent air conditioner is required to heat the cab or power cabin, which consumes the useful work of the engine and increases fuel consumption, and a lot of heat is directly discharged with the engine exhaust, causing great waste
