Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to a cooling module for new energy vehicles with a front-mounted radiator. Background Technology

[0002] An automotive cooling module typically includes a radiator, a condenser, and an electric fan. The radiator provides cooling for the vehicle's power components, the condenser generally provides comfortable cooling for the passenger compartment, and the electric fan provides sufficient airflow for heat exchange.

[0003] In conventional cooling modules for gasoline vehicles, the radiator is typically placed in the middle, serving as the main structure for fixed support. Two shock-absorbing pads are mounted on the top and bottom, and the condenser is placed in front of it and fixed to the water chambers on both sides of the radiator. The electric fan is placed behind it and also needs to be fixed through the water chambers on both sides of the radiator.

[0004] However, pure electric vehicles lack an engine; the radiator primarily cools the motor. The motor's operating temperature and heat output are significantly lower than those of a traditional gasoline engine. If the radiator remains behind the condenser, the temperature difference between the condenser's outlet air temperature and the target temperature of the radiator's water-side outlet is too small, requiring a larger radiator to meet motor cooling needs, resulting in wasted cost and space. Placing the condenser in the middle perfectly meets the thermal management requirements of pure electric vehicles. However, due to its structural limitations, the condenser typically has aluminum manifolds on both sides, which are profile structures and not suitable for providing mounting structures at the front and rear like a radiator. Current technology mainly involves designing a plastic mounting frame, providing mounting points for the condenser, radiator, and electric fan, and then connecting it to the vehicle as a whole. For example, a cooling module is described in patent application CN 214728164 U. However, this solution adds a frame, significantly increasing costs. Furthermore, the frame occupies the cooling module's heat dissipation area, resulting in lower cooling performance within the same space.

[0005] Existing cooling modules, limited by their fixed structural design, typically place the condenser at the front, with the radiator in the middle serving as a load-bearing component, and an electric fan mounted behind it. With the application of new energy vehicles, especially pure electric vehicles, the problems arising from this arrangement have become increasingly apparent. In high-temperature environments during summer, the condenser's outlet air temperature is usually quite high, while the subsequent low-temperature radiator is responsible for cooling the motor. The operating temperature of new energy vehicle motors is typically lower than that of traditional gasoline vehicle engines, requiring a sufficiently low intake temperature to ensure adequate motor cooling. However, placing the condenser at the front increases its intake air temperature, adding to the load on the radiator. This necessitates a larger design for both the condenser and radiator to meet the demands of air conditioning cooling and motor cooling, resulting in significant cost waste. Utility Model Content

[0006] This utility model provides a feasible and cost-effective arrangement scheme for placing the condenser after the low-temperature radiator in the front-end module. To achieve this, a new cooling module is provided, which adopts a novel electric fan structure. The electric fan connects to the vehicle and provides fixation for the condenser and radiator. This new cooling module also eliminates the traditional structure of plastic water chambers on both sides of the radiator, significantly reducing the development cost and unit cost of the radiator. The specific technical solution is as follows:

[0007] A front-mounted cooling module for new energy vehicles includes a radiator, a condenser, and an electric fan housing. The radiator is located at the front end of the condenser, and the electric fan housing is located at the rear end of the condenser. Upper and lower mounting shafts are provided at the upper and lower ends of one side of the electric fan housing, connecting the cooling module to the vehicle. A locking part is provided in the middle of the side of the electric fan housing with the upper and lower mounting shafts, matching the condenser manifold and liquid reservoir to fix the condenser. Water chambers are provided on the left and right sides of the radiator, each with an aluminum profile frame. Aluminum partitions are provided above and below the aluminum profile frame and welded together, forming a water chamber cavity between the two aluminum partitions.

[0008] Furthermore, upper and lower shock-absorbing pads are installed on the upper and lower mounting shafts before being connected to the vehicle.

[0009] Furthermore, the locking portion is respectively locked to the arc features of the left and right manifolds of the condenser or the liquid storage tank, and is provided with an interference fit to ensure the stability of the locking.

[0010] Furthermore, the snap-fit ​​portion is configured as two or three separate segments to ensure the assembly flexibility of the snap-fit ​​structure.

[0011] This invention optimizes the structure of the electric fan's air guide cover. By designing the electric fan with a snap-fit ​​structure, the condenser and electric fan are snapped together via a manifold. This reduces the need for the four mounting brackets welded to the left and right sides of the condenser in traditional cooling modules, as well as the mounting bolts between the condenser and the radiator. The traditional upper and lower shock-absorbing sleeves and their mounting shafts of the cooling module are integrated into the electric fan's air guide cover. The low-temperature radiator structure is simplified by using a lower-cost aluminum profile similar to the condenser's manifold as the water chamber, replacing the plastic parts that originally required injection molding. This results in reduced size, weight, and cost. The heat dissipation area is increased, leading to improved performance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] A front-mounted cooling module for new energy vehicles includes a radiator 6, a condenser 5, and an electric fan housing 7. The radiator 6 is located at the front end of the condenser 5, and the electric fan housing 7 is located at the rear end of the condenser 5. Upper and lower mounting shafts 1 are provided at the upper and lower ends of one side of the electric fan housing, through which the cooling module is connected to the vehicle. A locking part 2 is provided at the middle of one side of the electric fan housing 7 where the upper and lower mounting shafts 1 are located. This locking part 2 matches the condenser manifold and the liquid storage tank to fix the condenser. Water chambers 4 are provided on the left and right sides of the radiator 6. The water chambers 4 are made of aluminum profile frames, and aluminum partitions 10 are provided above and below the aluminum profile frames and welded to them, forming a water chamber cavity between the two aluminum partitions.

[0027] Upper and lower damping pads 8 are installed on the upper and lower mounting shafts and then connected to the vehicle. The locking part 2 is respectively locked with the arc features of the left and right manifolds of the condenser 5 or the liquid storage tank, and is provided with an interference fit to ensure the stability of the locking fixation. The locking part 2 is set as two or three separate sections to ensure the assembly flexibility of the locking structure.

[0028] like Figure 2 An upper and lower mounting shaft 1 structure is designed on the electronic fan housing 7 to connect with the vehicle. After the upper and lower shock-absorbing pads are installed here, it is connected to the vehicle. A snap-fit ​​part 2 is designed on the electronic fan housing 7 to match the condenser manifold and the liquid reservoir, so as to fix the condenser 5.

[0029] like Figure 6 The locking part 2 is respectively locked into the arc features of the left and right condenser flow pipes or the liquid storage tank, and is designed with a suitable locking interference to ensure the stability of the locking fixation. Figure 9 The snap-fit ​​structure has been designed with a break in the middle to ensure the assembly flexibility of the snap-fit ​​structure.

[0030] like Figure 4 The radiator has six water chambers on each side, designed with a low-cost aluminum profile structure, similar to the manifold structure of a condenser; such as Figure 11 The water chamber is formed by welding aluminum profile tubes and upper and lower partitions. Compared to traditional radiator water chambers (such as...), this design... Figure 10 Its water chamber is composed of a plastic water chamber and an aluminum stamped main piece. Its development cost is high, it occupies a large area, and the crimping assembly requires special tooling. The labor and tooling mold development costs are higher than the solution adopted in this utility model.
