Description

Technical Field

[0001] This utility model relates to the field of vehicle body structure, specifically to a commercial vehicle frame with a side-mounted air conditioning cooling device and the commercial vehicle thereof. Background Technology

[0002] In the commercial vehicle sector, the heat dissipation and cooling performance of the air conditioning system is a key factor in ensuring the overall vehicle's thermal management efficiency and passenger comfort. Currently, commercial vehicle air conditioning cooling devices generally adopt a layout design that overlaps with the engine radiator and is mounted on the chassis assembly, relying primarily on the engine fan and the airflow generated during vehicle operation for passive cooling. While this traditional structure had certain cost advantages and space utilization in early designs, its limitations have gradually become apparent as vehicle performance requirements have increased and operating conditions have become more complex.

[0003] In practical use, when the air conditioning radiator is installed in front of the engine radiator, the high-temperature heat radiation generated during engine operation directly affects the heat exchange efficiency of the air conditioning radiator. Due to the high temperature in the engine compartment, the surface temperature of the air conditioning radiator rises accordingly, leading to increased refrigerant outlet temperature, poor refrigerant liquefaction, and reduced cooling capacity. This heat radiation interference not only affects the driving experience but may also cause the air conditioning to fail due to system overheating.

[0004] Furthermore, the overlapping installation structure causes the air conditioning radiator and the engine radiator to share the same airflow passage, resulting in double resistance to the airflow. Especially when the vehicle is traveling at low speeds or idling, the engine fan needs to overcome greater wind resistance to maintain airflow speed. This cumulative wind resistance effect can easily lead to insufficient engine cooling, which in turn causes problems such as increased water temperature, decreased powertrain performance, and reduced fuel economy, creating a vicious cycle.

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0040] This application provides a commercial vehicle frame with a side-mounted air conditioning cooling device and the commercial vehicle thereof, which can solve the problems of the layout design in the prior art where the air conditioning cooling device and the engine radiator are overlapped and installed on the frame assembly, which easily leads to low heat exchange efficiency of the air conditioning radiator, poor air conditioning cooling, and reduced heat dissipation capacity of the engine radiator, high water temperature, power system performance degradation, and reduced fuel economy.

[0041] Reference Figure 1 This application discloses a commercial vehicle frame with a side-mounted air conditioning cooling device and the commercial vehicle thereof, including a frame assembly 1, a front axle 13, a side-mounted mounting bracket 2, an air conditioning cooling component 3, and an engine cooling device 4. The frame assembly 1 includes a frame crossbeam 11 and a frame longitudinal beam 12, which are connected to each other to form a rectangular frame. The two ends of the front axle 13 in the length direction are respectively connected to the frame crossbeam 11, and the front axle 13 is set close to the frame longitudinal beam 12 in the front direction of the vehicle. A front mounting section 14 is formed between the front axle 13 and the frame longitudinal beam 12. The side-mounted mounting bracket 2 is set on the frame longitudinal beam 12. The installation position of the side-mounted mounting bracket 2 is located within the front mounting section 14 and the side-mounted mounting bracket 2 is located outside the frame assembly 1. The air conditioning cooling component 3 is set on the side-mounted mounting bracket 2. The engine cooling device 4 is set at the bottom of the front axle 13 and located inside the frame assembly 1. By adding a side-mounted bracket 2 to the outside of the frame assembly 1, the air conditioning cooling component 3 and the engine cooling device 4 are installed at different positions on the frame assembly 1, making the air conditioning cooling component 3 and the engine cooling device 4 independent of each other. This reduces the mutual influence between the air conditioning cooling component 3 and the engine cooling device 4, effectively improving the engine's heat dissipation capacity and reducing engine failures caused by high water temperature. At the same time, the side-mounted bracket 2 is located in the front mounting section 14, which is close to the front of the vehicle and is specifically located between the headlight and the front axle 13 in actual installation. Utilizing the frame layout characteristics of commercial vehicles, the installation position of the air conditioning cooling component 3 is changed without interfering with other frame structures. This solves the problems of the existing layout design where the air conditioning cooling device and the engine radiator are overlapped and installed on the frame assembly 1, which easily leads to low heat exchange efficiency of the air conditioning radiator, poor air conditioning cooling, and reduced heat dissipation capacity of the engine radiator, high water temperature, power system performance degradation, and reduced fuel economy.

[0042] More specifically, refer to Figure 2 The air conditioning cooling assembly 3 includes an air conditioning radiator 31, a refrigerant reservoir 311, an air conditioning compressor 32, and an air conditioning control system. The air conditioning radiator 31 is bolted to a side-mounted bracket 2. The refrigerant reservoir 311 is located at the refrigerant outlet of the air conditioning radiator 31 to provide cold air storage for the radiator 31. The air conditioning compressor 32 is mounted on the longitudinal beam 12 of the vehicle frame and is located inside the vehicle frame assembly 1. The air inlet of the air conditioning compressor 32 is connected to the hot end of the air conditioning radiator 31, and the outlet of the air conditioning compressor 32 is connected to the refrigerant reservoir 311. The coolant in the refrigerant reservoir 311 vaporizes simultaneously with the high temperature after being blown out by the air conditioning radiator 31, and enters the air conditioning compressor 32 through the hot end of the air conditioning radiator 31. The air conditioning compressor 32 liquefies the hot air at a low temperature and then enters the refrigerant reservoir 311, thus forming a complete hot and cold cycle chain, which can continuously provide cooling conditions for the air conditioning radiator 31 and reduce the frequency of maintenance.

[0043] In one embodiment of this application, the air inlet of the air conditioning compressor 32 is connected to an air conditioning high-pressure pipe 313, the other end of the air conditioning high-pressure pipe 313 is connected to the hot end of the air conditioning radiator 31, the outlet end of the air conditioning compressor 32 is connected to an air conditioning low-pressure pipe 312, and the other end of the air conditioning low-pressure pipe 312 is connected to the liquid end of the refrigerant storage tank 311, thereby forming a hot and cold cycle.

[0044] To further improve the cooling effect and heat dissipation efficiency of the air conditioner radiator 31, the air conditioner cooling assembly 3 also includes a cooling fan 33. The cooling fan 33 is mounted on the side mounting bracket 2, with its air intake facing the air conditioner radiator 31. The cooling fan 33 is connected to the air conditioner control system. When the air conditioner control system turns on the cooling fan 33, it draws air into the air conditioner radiator 31, thereby improving the heat dissipation efficiency of the air conditioner radiator 31.

[0045] To further improve the automation performance of the cooling fan 33, ensuring that the air conditioning control system only activates the cooling fan 33 when the refrigerant temperature is too high or liquefaction is poor, thereby reducing energy consumption, the air conditioning cooling assembly 3 also includes a temperature regulator. The output of the temperature regulator is connected to the cooling fan 33 and is used to control the cooling intensity of the air conditioning radiator 31 and the operating power of the cooling fan 33. In one embodiment of this application, the temperature regulator is connected to the air conditioning control system for integrated control, making it more convenient and practical. The temperature regulator's input is connected to a temperature sensor 34, which is located at the refrigerant outlet of the air conditioning radiator 31. The temperature sensor 34 transmits the refrigerant temperature at the outlet of the air conditioning radiator 31 to the temperature regulator in real time. The temperature regulator can be pre-set with high and low refrigerant temperature thresholds. When the real-time temperature at the refrigerant outlet of the air conditioning radiator 31 exceeds the high threshold, the temperature regulator activates the cooling fan 33 for auxiliary air intake. When the real-time temperature at the refrigerant outlet of the air conditioning radiator 31 is below the low threshold, the air conditioning radiator 31 can rely on the wind during vehicle operation for heat dissipation, and the temperature regulator deactivates the cooling fan 33 to reduce energy consumption. Furthermore, the temperature regulator can automatically adjust the operating speed of the cooling fan 33 based on how much the actual temperature at the refrigerant outlet of the air conditioning radiator 31 exceeds the threshold temperature, thereby adjusting the cooling intensity of the air conditioning fan 33 and ensuring that the refrigerant temperature at the outlet of the air conditioning radiator 31 is always controlled within the effective refrigerant liquefaction temperature range, enhancing the air conditioning cooling effect.

[0046] Furthermore, in order to guide the airflow direction of the cooling fan 33, a protective ring 331 is also provided on the cooling fan 33 to concentrate the airflow direction of the cooling fan 33 and further enhance the auxiliary cooling efficiency of the cooling fan 33.

[0047] More specifically, in one embodiment of this application, the side mounting bracket 2 specifically includes a connecting piece 21, with integrally formed fixing lugs 22 at both ends of the connecting piece 21. One fixing lug 22 is connected to the air conditioning radiator 31, and the other fixing lug 22 is connected to the frame longitudinal beam 12. An angle exists between the fixing lug 22 and the connecting piece 21, allowing the air conditioning radiator 31 to be installed at an angle to the outside of the frame longitudinal beam 12 sidewall, better avoiding other frame mounting structures and making it more convenient to use. Furthermore, the connecting piece 21 also has a perforated hole 211 along its length to adapt to the trend of lightweight frame installation and reduce the overall weight of the side mounting bracket 2.

[0048] In addition, this application also discloses a commercial vehicle, which includes a commercial vehicle frame with an air conditioning side-mounted cooling device as described above, solving the problem that the layout design of the air conditioning cooling device and the engine radiator overlapping and being installed on the frame assembly 1 in the prior art easily leads to the heat exchange efficiency of the air conditioning radiator 31, water temperature rise, power system performance degradation and fuel economy decline.
