Description

[0002] With the increasing emphasis on the safety of fuel cell vehicles by people, the temperature control of the fuel cell working environment has become more and more strict. When the vehicle runs under different working conditions, the fuel cell thermal management system needs to ensure that the fuel cell works within an efficient and safe temperature range, so the reliability of the fuel cell cooling system.

[0003] In the existing fuel cell vehicle technology, there are mainly two cooling methods: one is to extend the pipeline to the components to be cooled for liquid cooling, and the other is to directly use a fan for air cooling. However, the problem brought by the former is that the coolant circulation pipeline extends to the components to be cooled, increasing the complexity of the pipeline and the cooling and heat dissipation pressure, making the vehicle layout extremely difficult; while the latter, since the cooling air enters from the bottom of the vehicle, seriously affects the corresponding IP level of the cooling fan. At the same time, the cooling air enters the passenger compartment through a simple pipeline. If there are problems with the components and fires, explosions and other problems occur, the flame directly enters the passenger compartment, posing a great safety hazard.

[0027] As Figures 1 to 3 shown, it is a heat dissipation integrated device of an embodiment of the present utility model.

[0028] Please refer to Figures 1 - 3 , the heat dissipation integrated device of the embodiment of the present utility model includes a fuel cell heat dissipation structure 10, an air conditioner condenser 20, and a motor and electronic control radiator 40. The motor and electronic control radiator 40 is disposed in front of the fuel cell heat dissipation structure 10 and supported on the fuel cell heat dissipation structure 10. The air conditioner condenser 20 is disposed between the fuel cell heat dissipation structure 10 and the motor and electronic control radiator 40 and is connected to the fuel cell heat dissipation structure 10 and / or the motor and electronic control radiator 40.

[0029] During use, the fuel cell heat dissipation structure 10, the air conditioner condenser 20, and the motor and electronic control radiator 40 are all integrated and arranged under the front of the fuel cell vehicle. The motor and electronic control radiator 40 is in the front, the air conditioner condenser 20 is in the middle, and the fuel cell heat dissipation structure 10 is arranged at the rear.

[0030] Understandably, one of the air conditioner condenser 20 and the power battery condenser 30 can be connected to the fuel cell heat dissipation structure 10, and the other can be connected to the motor and electronic control radiator 40. It is also possible that both are connected to the fuel cell heat dissipation structure 10, or both are connected to the motor and electronic control radiator 40. Specific limitations are not made here.

[0031] In this embodiment, by integrating the fuel cell heat dissipation structure 10, the air conditioner condenser 20, and the motor and electronic control radiator 40 together, the heat dissipation requirements of the entire system can be managed more effectively. This centralized design enables heat to be transferred and dissipated more quickly, improving the heat dissipation efficiency. Moreover, within a limited space, through reasonable layout and support structures, the compact installation of multiple radiators can be achieved, thereby optimizing the space utilization.

[0032] Please refer to Figure 1 and Figure 3 As shown, exemplarily, in some embodiments, the fuel cell heat dissipation structure 10 includes a fuel cell high-pressure blower 11 and a fuel cell radiator 12. The fuel cell high-pressure blower 11 is arranged behind the fuel cell radiator 12, and the motor and electronic control radiator 40 is arranged in front of the fuel cell radiator 12. The forced convection method can be used to accelerate the air flow around the fuel cell radiator 12 and improve the heat dissipation efficiency. The air flow generated by the fuel cell high-pressure blower 11 can act more directly on the radiator surface and take away more heat.

[0033] When the fuel cell starts running and the user starts the air conditioner, the blower maintains the rotation speed according to the fuel cell demand, checks the signals of the in-vehicle temperature sensor, the air conditioner condenser 20 temperature sensor, and the out-of-vehicle environment sensor. When the in-vehicle temperature > 26°C, the out-of-vehicle environment temperature is detected. According to the calibrated comparison table, the initial power of the air conditioner compressor and the initial rotation speed of the blower are determined, and the temperature of the air conditioner condenser 20 is controlled between 2 - 3°C. According to the change of the in-vehicle temperature, the power of the air compressor and the air volume of the air conditioner are adjusted. When the temperature of the air conditioner condenser 20 approaches 0°C, while keeping the rotation speed of the blower unchanged, the power of the air conditioner compressor is gradually reduced to make the in-vehicle temperature reduction curve smooth.

[0034] Please refer to Figure 1 and Figure 3 As shown, exemplarily, in some embodiments, there are also two first auxiliary brackets 50 and two second auxiliary brackets 60. The upper left and upper right parts of the motor and electronic control radiator 40 are respectively connected to the left and right sides of the fuel cell heat dissipation structure 10 through the two first auxiliary brackets 50, and the bottom of the motor and electronic control radiator 40 is respectively connected to the front of the fuel cell heat dissipation structure 10 through the two second auxiliary brackets 60. The connection method is simple and reliable.

[0035] The first auxiliary bracket 50 is provided with a first fixing portion 51 connected to the motor and electronic control radiator 40 and a second fixing portion 52 connected to the fuel cell power generation heat dissipation structure 10. Similarly, the second auxiliary bracket 60 is provided with a third fixing portion 61 connected to the motor and electronic control radiator 40 and a fourth fixing portion 62 connected to the fuel cell power generation heat dissipation structure 10. The first fixing portion 51 and the motor and electronic control radiator 40, the second fixing portion 52 and the fuel cell power generation heat dissipation structure 10, the third fixing portion 61 and the motor and electronic control radiator 40, and the fourth fixing portion 62 and the fuel cell power generation heat dissipation structure 10 are all connected by screws, which is easy to disassemble and maintain.

[0036] Furthermore, it further includes a fuel cell power generation installation bracket 70. The fuel cell power generation installation bracket 70 is arranged in a U shape and includes a first installation portion 71, a second installation portion 72, and a connecting portion 73 connecting the first installation portion 71 and the second installation portion 72. There are two fuel cell power generation installation brackets 70, and the two fuel cell power generation installation brackets 70 are respectively sleeved on the left side and the right side of the fuel cell power generation heat dissipation structure 10. By providing the fuel cell power generation installation bracket 70, the forces and vibrations from various directions can be effectively dispersed and borne, ensuring the stability and reliability of the heat dissipation system during operation.

[0037] Furthermore, the upper left side and the upper right side of the motor and electronic control radiator 40 are respectively connected to the connecting portion 73 of the two fuel cell power generation installation brackets 70 through two first auxiliary brackets 50, and the bottom of the motor and electronic control radiator 40 is respectively connected to the second installation portion 72 of the two fuel cell power generation installation brackets 70 through two second auxiliary brackets 60. The motor and electronic control radiator 40 is tightly connected to the fuel cell power generation installation bracket 70 through the first auxiliary bracket 50 and the second auxiliary bracket 60, and the connection method is simple and reliable.

[0038] Please refer to Figures 1 - 3 As shown, exemplarily, in some embodiments, when there are both fuel cells and power batteries in a vehicle, the fuel cell heat dissipation integration device further includes a power battery condenser 30. The air conditioner condenser 20 and the power battery condenser 30 are arranged one above the other between the fuel cell power generation heat dissipation structure 10 and the motor and electronic control radiator 40 and are respectively connected to the fuel cell power generation heat dissipation structure 10 and / or the motor and electronic control radiator 40. A large amount of heat is generated during the charging and discharging process of the power battery. If it is not dissipated in time, the battery temperature will rise sharply, affecting the performance and lifespan of the battery. The power battery condenser 30 effectively dissipates the heat generated in the battery to the external environment through its heat dissipation function, thereby reducing the battery temperature.

[0039] It can be understood that one of the air conditioner condenser 20 and the power battery condenser 30 can be connected to the fuel cell power generation heat dissipation structure 10, and the other can be connected to the motor and electronic control radiator 40. They can also both be connected to the fuel cell power generation heat dissipation structure 10, or both be connected to the motor and electronic control radiator 40. Specific limitations are not made here.

[0040] Specifically, the air conditioner condenser 20 is disposed above the power battery condenser 30.

[0041] In this embodiment, by integrating the fuel cell heat dissipation structure 10, the air conditioner condenser 20, the power battery condenser 30, and the motor electronic control radiator 40 together, the heat dissipation requirements of the entire system can be managed more effectively.

[0042] Furthermore, it further includes a first condenser fixing bracket 80 and a second condenser fixing bracket 90 that are respectively detachably connected to the fuel cell heat dissipation structure 10. There are four first condenser fixing brackets 80, which are respectively disposed at the upper left, lower left, upper right, and lower right positions of the air conditioner condenser 20 and are snap-connected to the air conditioner condenser 20. There are four second condenser fixing brackets 90, which are respectively disposed at the upper left, lower left, upper right, and lower right positions of the power battery condenser 30 and are snap-connected to the power battery condenser 30. The connection method is simple and reliable.

[0043] Specifically, the first condenser fixing bracket 80 and the second condenser fixing bracket 90 are respectively detachably connected to the fuel cell installation bracket 70.

[0044] Please refer to Figure 1 As shown, exemplarily, in some embodiments, it further includes a fixing frame 100. There are two fixing frames 100, which are respectively disposed on the two side surfaces of the fuel cell heat dissipation structure 10 and extend outward. The fixing frame 100 is used to connect to the vehicle frame of the fuel cell vehicle, thereby fixing the heat dissipation integration device under the front of the fuel cell vehicle. The fixing method is simple and reliable.
