Abstract
The utility model discloses a fuel cell electric vehicle mainly auxiliary condenser heat transfer enhancement intelligent air-conditioning system, comprising a condenser, a radiator, a fan and a spraying device. The primary or secondary condenser of air-conditioning are connected with the major-minor radiator of FCE and PCU radiator, of which are two suction fans at the front, providing a primary or secondary condenser assembly and a spraying device at other places on the system, to the secondary cooling refrigerant from the primary condenser through the secondary condenser. At the condition of not having effects on FCE heat dissipating, the utility model mainly uses the auxiliary condenser and heat transfer enhancement to meet the refrigerant requirement of fuel cell electric vehicle air-conditioning.
Description
Technical field
The utility model relates to a kind of a/c system, particularly a kind of a/c system that has major-minor condenser that is used on the fuel cell electric vehicle.
Background technology
At present, at traditional car, the air-conditioning condenser riding position generally before engine radiator, because the air-conditioning refrigerant condensing temperature is lower than engine outlet water temperature, therefore can not influence the engine radiator radiating effect.
And for the fuel cell electric vehicle of existing research and development, to reach 80 ℃ owing to the air-conditioning refrigerant condensing temperature is the highest and be higher than 65 ℃ of fuel cell pile (FCE) leaving water temperatures, if therefore air-conditioning condenser and fuel cell pile (FCE) radiator still adopt the placement form that forward laps, can make condenser at heat-dissipation simultaneously to fuel cell pile (FCE) radiators heat, thereby influence the radiating effect of fuel cell pile (FCE) radiator.
Summary of the invention
Technical problem to be solved in the utility model is the heat dissipation problem that fuel battery electric sedan exists, the major-minor condenser augmentation of heat transfer of a kind of fuel cell electric vehicle intelligent air-conditioning system now is provided, when guaranteeing the radiating effect of fuel battery electric sedan fuel cell pile (FCE) radiator, also satisfied the heat radiation requirement of its air conditioner refrigerating.
The technical solution of the utility model is: the major-minor condenser augmentation of heat transfer of a kind of fuel cell electric vehicle intelligent air-conditioning system comprises condenser, radiator, blower fan, atomising installation.
Be arranged together before and after major and minor radiator of air-conditioning first-stage condenser or secondary condenser and FCE and the PCU radiator, the front is provided with two air draught blower fans, an air-conditioning secondary condenser or air-conditioning first-stage condenser assembly are set on other positions of system and install an atomising installation additional, be used for the refrigerant that first-stage condenser comes out and carry out the secondary cooling through secondary condenser again.
Back or air-conditioning secondary condenser that the air-conditioning first-stage condenser is arranged in the FCE radiator are placed on the preceding windward side of FCE radiator.
The utility model adds a condenser again on original single air-conditioning condenser basis, make the refrigerant of the High Temperature High Pressure of coming out carry out the one-level cooling through first-stage condenser earlier through compressor, its temperature is decreased, carry out the secondary cooling by secondary condenser again.Simultaneously for better cooling performance is arranged, can be at the other atomising installation that installs additional of air-conditioning condenser, in case of necessity condenser is sprayed some vaporific droplets and come augmentation of heat transfer, use thisly to reach water and the air-conditioning condensate water that water source that the flash heat transfer method requires can produce when being the fuel cell electric vehicle work of the energy with hydrogen by globule vaporization and obtain.
The utility model is not influencing under the FCE heat-dissipation situation, satisfies the refrigeration requirement of fuel-cell vehicle electric air-conditioning system by utilizing major-minor condenser and augmentation of heat transfer mode.
Description of drawings
Fig. 1 is that the utility model is implemented a fundamental diagram;
Fig. 2 is that the utility model is implemented two fundamental diagrams.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, embodiment one
The utility model is by blower fan 1, air-conditioning first-stage condenser 2, FCE master's radiator 3, FCE secondary radiator 4, wind input direction 5, air-conditioning ECU (Electrical Control Unit) 6, water pump 7, water tank 8, shower nozzle 9, air-conditioning secondary condenser 10, PCU radiator 11 compositions such as grade.
Air-conditioning first-stage condenser 2 placement locations and FCE radiator 3,4 and PCU radiator 11 front and back are arranged together, and utilize two blower fan air draughts 1, arrange air-conditioning secondary condenser 10 assemblies simultaneously in other positions again and have installed an atomising installation 9 additional.Because the refrigerant through first-stage condenser 2 is the high temperature and high pressure gaseous refrigerant that directly comes out from compressor, this moment, refrigerant temperature was than FCE water outlet water temperature height, consider and to make FCE radiator 3,4 that better radiating effect is arranged, to be arranged in air-conditioning first-stage condenser 2 back of FCE radiator 3,4, make air intake at first pass through first-stage condenser 2 again by FCE radiator 3,4.But layout will certainly influence the heat radiation requirement of air conditioner refrigerating like this, so that the refrigerant that comes out from first-stage condenser 2 carries out the secondary cooling through secondary condenser 10 again, consider that simultaneously the summer vehicle vehicle interior temperature that is exposed to the sun for a long time is higher under the sun, for heat radiation more quickly and effectively, can on the basis of utilization secondary condenser 10, come enhance heat with 9 pairs of air-conditioning secondary condensers of atomising installation, 10 some little mist pearls of spray.Can utilize air-conditioning ECU (Electrical Control Unit) 6 according to the operation of air conditioner operating mode, condensing temperature is just controlled the correlation behaviors such as injection flow rate of whether using atomising installation 9 enhance heats or control setup.
Embodiment two
As shown in Figure 2, the utility model is by blower fan 1, air-conditioning secondary condenser 2, FCE master's radiator 3, FCE secondary radiator 4, wind input direction 5, air-conditioning ECU (Electrical Control Unit) 6, water pump 7, water tank 8, shower nozzle 9, air-conditioning first-stage condenser 10, PCU radiator 11 compositions such as grade.
Air-conditioning secondary condenser 2 placement locations and FCE radiator preceding 3,4 and PCU radiator 11 front and back are arranged together, and utilize two blower fan air draughts 1, arrange air-conditioning first-stage condenser 10 assemblies simultaneously in other positions again and have installed an atomising installation 9 additional.The high-temperature high-pressure refrigerant that compressed machine compression back forms is at first by first-stage condenser 10 coolings, then through secondary condenser 2 coolings, decrease through first-stage condenser 10 cooled refrigerant temperatures, can't influence its radiating effect to 3,4 heating of FCE radiator so air-conditioning secondary condenser 2 is placed on FCE radiator 3,4 preceding windward sides.Consider that simultaneously the summer vehicle vehicle interior temperature that is exposed to the sun for a long time is higher under the sun,, can be used on the basis of secondary condenser, come enhance heat with 9 pairs of first-stage condenser of atomising installation, 10 some little mist pearls of spray for heat radiation more quickly and effectively.Can utilize air-conditioning ECU (Electrical Control Unit) 6 according to the operation of air conditioner operating mode, condensing temperature is just controlled the correlation behaviors such as injection flow rate of whether using atomising installation 9 enhance heats or control setup.
