Description
Technical field
Exhaust heat heating system of fuel cell vehicle belongs to the Vehicle heating technical field.
Background technology
Fuel cell is to utilize fuel chemical energy to be converted into the device of electric energy and heat energy, and wherein the heat energy of Chan Shenging accounts for 50% of fuel chemical energy.The electric energy that adopts now fuel cell only to utilize fuel cell to produce at present as the vehicle of driving engine, the heat energy of generation is not used but directly discharges.And direct electrically heated mode is all adopted in the heating in winter in the present fuel-cell vehicle, consume a large amount of high-grade energy (electric energy), increased the consumption of fuel of fuel-cell vehicle, if can adopt the waste heat of fuel cell itself to be used for to Vehicle heating, to improve the economy of vehicle greatly, make that fuel-cell vehicle usefulness can be more reasonable.Because the fuel cell cooling water expansion tank adopts deionized water, therefore in heating system, also need solve the Ionized problem of deionized water that prevents.
By retrieval, do not see the relevant open source literature that utilizes the fuel cell waste heat to give Vehicle heating.
Summary of the invention
Has a large amount of waste heats at existing fuel-cell vehicle itself, and adopt direct electro heat heating to cause the big problem of power consumption, the present invention proposes a kind of fuel-cell vehicle exhaust heat heating system that adopts the heat pipe Intermediate Heat Exchanger, and the Ionized problem of solution deionized water, save vehicle and be used to the power consumption that heats, improve the economy of vehicle.
The present invention contains the fuel cell cooling loop, it is characterized in that, also contains a heating pipeline, and described cooling loop passes to heating pipeline by an Intermediate Heat Exchanger with heat; One section by passage is arranged between the entrance and exit of fuel cell radiator, an automatically controlled triple valve is housed in the entrance of described by passage and fuel cell radiator; A shutoff valve is housed on described heating pipeline; The hot side of described Intermediate Heat Exchanger is connected on the cooling line, and cold side is connected on the heating pipeline; On described heating loop, water pump and heat abstractor are housed also.
The material of described cooling loop is a corrosion-resistant steel.
Described Intermediate Heat Exchanger is the hot tube heat exchanger of stainless steel material.
Evidence: native system can effectively utilize the waste heat of fuel cell to give Vehicle heating, has reached its intended purposes.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Accompanying drawings the specific embodiment of the present invention.
Residual heat pump air conditioner system for fuel-cell vehicle contains fuel cell cooling loop and heating pipeline, connects by Intermediate Heat Exchanger between two loops, and the heat of refrigerant fluid in the cooling loop is passed to heating pipeline.
The fuel cell radiator is housed on cooling loop, one section by passage is arranged between the entrance and exit of fuel cell radiator, a triple valve is housed at the inlet of by passage and fuel cell radiator or the junction of outlet; A shutoff valve is housed on heating pipeline; The hot side of Intermediate Heat Exchanger is connected on the cooling line, and cold side is connected on the heating pipeline.
As shown in Figure 1, fuel battery engines 1, cooling loop water pump 2, heating loop water pump 3, compartment radiator 4, shutoff valve 5, triple valve 6, fuel cell radiator 7, cooling line 8, Intermediate Heat Exchanger 9, heating pipeline 10.Fuel battery engines 1 cooling water outlet links to each other with water pump 2 imports, water pump 2 outlets link to each other with Intermediate Heat Exchanger 9 hot side-entrances, Intermediate Heat Exchanger 9 hot side outlets link to each other with triple valve 6 imports, 6 two outlets of triple valve link to each other with the two ends of fuel cell radiator 7 respectively, the outlet of Intermediate Heat Exchanger 9 cold sides links to each other with water pump 3 imports, water pump 3 outlets link to each other with compartment radiator 4 inlets, and radiator 4 outlets in compartment link to each other with shutoff valve 5 inlets, and shutoff valve 5 outlets link to each other with Intermediate Heat Exchanger 9 cold sides inlet.
Intermediate Heat Exchanger 9 is a hot tube heat exchanger, and the heat pipe heat exchanging modulator material is a corrosion-resistant steel, prevents the ionization of deionization cooling water expansion tank.Fuel cell cooling loop 8 piping materials also are corrosion-resistant steel.Cooling loop water pump 2 and driving power be direct current 24V, the heating water pump 3 driving power be direct current 24V, the driving power of triple valve 6 is direct current 24V, the driving power of compartment radiator 4 blower fans is direct current 24V.
Working process is: in the winter time during operating mode, open shutoff valve 5, when fuel battery engines 1 starts, by control triple valve 6 bypass fuel battery engine radiatores 7, refrigerant fluid exports to import through Intermediate Heat Exchanger 9 from fuel battery engines, the heat of getting in return by Intermediate Heat Exchanger 9 heats to the compartment by the heating loop, and the water pump 3 in the loop of wherein heating and fan 4 adopt hand switch control.When the cooling-liquid temperature at triple valve 6 places is elevated to setting value 1 (this setting value 1 is the limit value of fuel cell to cooling-liquid temperature), control triple valve 6 allows coolant flow through fuel battery engines radiator 7, opens fuel battery engines radiator cooling fan simultaneously.When the cooling-liquid temperature at triple valve 6 places is lower than setting value 2, control triple valve 6 bypass fuel battery engine radiatores 7.Setting value 2 is for avoiding the frequent smaller value of the ratio setting value set 1 of opening of triple valve.
When summer condition, owing to do not need heating, close shutoff valve 5, control triple valve 6 allows refrigerant fluid dispel the heat through fuel battery engines radiator 7.
The present invention has following advantage:
1. energy-conservation, utilize originally directly that the fuel cell waste heat of discharging heats to vehicle, saved and originally be used for the height that heats The taste electric energy has been saved fuel consumption, greatly improves the fuel-cell vehicle economy.
2. simple in structure, adopt the heating of fuel cell engine exhaust heat, simple in structure, control is easy to realize easily, can be fuel The car chamber of battery car provides suitable heat.
