An Engine Cooling Circulation System Utilizing Exhaust Pipe Auxiliary Heating

Abstract

The invention relates to an engine cooling circulation system for auxiliary heating through an exhaust pipe. The problems that power consumption for auxiliary heating of an existing cooling circulation system warmer is high, and an exhaust pipe is changed substantially for an existing tail gas water heating device are solved. The system comprises a small cooling liquid circulation loop provided with an air conditioner air warming core, and a large cooling liquid circulation loop provided with a radiator, wherein a thermostat used for switching is arranged between the small cooling liquid circulation loop and the large cooling liquid circulation loop. The engine cooling circulation system is characterized in that the a tail gas heat exchange module is arranged in front of the air conditioner air warming core of the small cooling liquid circulation loop, the tail gas heat exchange module comprises the exhaust pipe and a water jacket capable of being separably clamped to the exhaust pipe, and the two ends of the water jacket are provided with a cooling liquid inlet and a cooling liquid outlet respectively. According to the engine cooling circulation system, the tail gas heat exchange module is arranged in front of the air conditioner air warming core of the small cooling liquid circulation loop, cooling liquid is heated through tail gas heat, the effect of an air conditioner for warming is improved, and the efficiency of an engine warmer is improved; the water jacket can be controlled to be clamped to or separated from the exhaust pipe through the thermostat, and overheating of the cooling liquid is avoided.

Description

technical field [0001] The invention relates to an engine cooling circulation device, in particular to an engine cooling circulation system utilizing an exhaust pipe for auxiliary heating. Background technique [0002] In the traditional engine cooling cycle, a large coolant circulation and a small coolant circulation are set. When the coolant temperature is low, the coolant small circulation is used to rapidly raise the temperature in a non-radiating circulation mode; when the coolant temperature reaches the design standard, Generally, when the temperature is 80-90°C, the large circulation of the coolant is switched so that the coolant can dissipate heat through the radiator. When the ambient temperature is low, after the engine is started, the initial temperature of the coolant is low and the heating is slow, and the heating effect of the air conditioner in the car is poor, which also affects the engine warm-up efficiency. There are two types of auxiliary heating currentl...
