Description

Water heating type warm-air device for intelligent automobile

Technical field

The utility model relates to a kind of automotive heatingn system, refers in particular to a kind of Based Intelligent Control water heating type warm-air device that can utilize engine coolant and exhaust heat simultaneously.

Background technology

Traditional automotive heatingn system utilizes the waste heat of the refrigerant fluid of driving engine to warm oneself or utilizes the independent thermal source heating, the less heating requirement that is not enough to satisfy the large and medium-sized passenger vehicle of cold district of heat but the waste heat that utilizes the refrigerant fluid of driving engine is warmed oneself, can satisfy the heating needs though utilize the independent thermal source heating, need consume fuel, heat cost is higher, and being discharged in the atmosphere of burning also can be caused environmental pollution.Also occurred the heater that utilizes refrigerant fluid and exhaust heat to heat simultaneously in recent years, but existed the engine cold-start difficulty, the compartment heats up slow, causes the cooling water expansion tank recoil to cause shortcomings such as engine load increasing after water temperature is too high.The utility model does not have requirements such as influence at automobile bodies heating, energy-saving and environmental protection and to driving engine, when utilizing engine coolant and exhaust heat, realize heating to the compartment by Based Intelligent Control.So just avoided the shortcoming of present automotive heatingn system fully.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides that a cover is intelligent, heat efficiency is high, energy-conserving and environment-protective, helps cold-starting and driving engine is not had the automotive heatingn system of influence.

The purpose of this utility model is such realization:

Water heating type warm-air device for intelligent automobile, comprise: exhaust feed heater, sensor, controller (ECU), the gas circuit actr, water route bypass actr, water pump, forced heat abstractor, defogger, exhaust feed heater is installed on the engine exhaust pipeline, link to each other by water pipe with engine-cooling system, described water pump is by motor-driven, be located between driving engine and the exhaust feed heater, the water inlet end of water pump links to each other with engine water jacket by water pipe, the water side links to each other with the water inlet end of exhaust feed heater by water pipe, be respectively equipped with gas circuit bypass actr and water route bypass actr at exhaust feed heater admission port and water outlet, gas circuit bypass actr links to each other with the water route bypass pipe with the gas circuit bypass pipe respectively with water route bypass actr, the gas circuit bypass pipe is connected with the exhaust feed heater air extractor duct, the water route bypass pipe is connected with return water pipe, described sensor is installed in the water outlet of exhaust feed heater, described controller links to each other with actr with sensor by lead, and forced heat abstractor and defogger are positioned at the compartment.

Described gas circuit bypass actr, water route bypass actr are electronically controlled triple valve.

The tube side heat exchanger tube of described exhaust feed heater is a helicoidal structure, and heat exchanger tube inside is cooling water expansion tank, and the heat exchanger tube shell side is outward a vehicle exhaust emissions.

Because the utility model has adopted said structure, and is compared with prior art rational in infrastructure, realized Based Intelligent Control: the occurs at low temperatures motivation starts the back and because of exhaust cooling water expansion tank is heated become easier, has reduced the wearing and tearing to driving engine; Efficiency of heating surface height; In the time of subzero 20 ℃, Engine Coolant Temperature can be heated to more than 40 ℃ in 10 minutes, in the time of subzero 40 ℃, engine water surely can be heated to more than 10 ℃ in 10 minutes, reach the engine starting temperature, prolonged the service life of driving engine; Energy-conservation not oil consumption, environmental protection more economically; Can carry out Based Intelligent Control when water is steady by actr when too high or too low,, driving engine not had influence with within the specific limits water temperature control.
