[0037] With the rapid development of the automotive industry, the development of various equipment and devices adapted to automobiles is also advancing rapidly. The vehicle air conditioning system is one of the most important structural components of a car. During vehicle operation, it promotes airflow within the vehicle and facilitates gas exchange with the outside environment, playing an indispensable role in defrosting and heat dissipation. Traditional automotive air conditioning systems, in practical use, primarily rely on an internal fan structure for air intake. However, this traditional internal fan structure often struggles to meet the demands for efficient cooling and defrosting when temperatures are high or low.

[0038] This utility model proposes a vehicle air conditioning structure 100 to solve the above problems.

[0039] Please see Figures 1 to 2 In one embodiment of this utility model, the vehicle air conditioning structure 100 includes a first housing 1, a temperature control device 2, and a pressurization structure 3. The first housing 1 includes an air inlet 11 and an air outlet 12. An air inlet 13 is provided on the first housing 1 at a position corresponding to the air inlet 11. An air outlet is provided at the end of the air outlet 12 away from the air inlet 11 for connecting to the vehicle's driver's cabin. The temperature control device 2 includes a fan structure 21 and an evaporator assembly 22. The fan structure 21 is installed in the air outlet 12 to form an airflow path from the air inlet 11 to the air outlet 12. The evaporator assembly 22 is installed in the air inlet 11 along the airflow path for heat exchange with the air. The pressurization structure 3 is installed at the air inlet 13 to increase the airflow volume in the air inlet 11.

[0040] It should be noted that the air conditioning structure in this solution is applicable to vehicle structures. Regarding the air intake structure of the air conditioning system, to meet the ventilation needs of the vehicle at high speeds, the air intake structure is generally positioned facing the front of the vehicle. Therefore, in the above embodiment, the air inlet 13 of the booster structure 3 is positioned facing the front of the vehicle. The opening direction of the booster device is defined as the front of the entire vehicle air conditioning structure 100, and the vertical direction is the arrangement direction of the air outlet 12 and the air inlet 11. Specifically, this can be combined with... Figure 1 The identifiers in the text are used for understanding.

[0041] In the above-described external circulation airflow scheme, air is drawn in through the pressurization structure 3. The airflow enters the air intake chamber 11 through the air inlet 13, flows into the air outlet chamber 12, and then flows into the vehicle's cabin through the air outlet on the air outlet chamber 12. When the entire circulation airflow is established, the fan structure 21 in the air outlet chamber 12 provides the airflow power, thereby forming the aforementioned external circulation airflow. The evaporator assembly 22 is the main heat exchange structure in the air conditioning system. Located in the airflow path, it can exchange heat with the air introduced into the air intake chamber 11, thereby adjusting the temperature of the air entering the vehicle's interior to meet actual usage requirements. The pressurization structure 3 is installed at the air inlet 13 and works in conjunction with the fan structure 21 to rapidly increase the air intake volume in the air intake cavity 11 in a short time. This, in turn, increases the unit air output volume at the air outlet, achieving rapid cooling or defrosting of the car interior. This further improves the ventilation and defrosting efficiency of the air conditioning system. Furthermore, it is known that in the same test structure, the higher the airflow velocity, the worse the filtration effect of the corresponding filter structure. When the vehicle is traveling at high speed, the pressurization structure 3 maintains a higher pressure inside the car compared to the external environment. When the airflow pressure at the air intake is high during high-speed driving, it slows down the air intake speed, thus improving the air filtration effect of the filter structure at the air intake and effectively reducing the pressure on the intake control structure, thereby improving the stability and service life of the entire intake structure.

[0042] To improve the overall compactness of the vehicle air conditioning structure 100 and minimize its impact on external wiring and structures, in this embodiment, the entire structure of the first housing 1 is mounted on the same bottom housing structure. Specifically, the first housing 1 includes a bottom housing 14, an air inlet cavity 11 located on the bottom housing 14, and an air outlet cavity 12 located above the air inlet cavity 11. In the horizontal direction, one end of the air outlet cavity 12 and one end of the bottom housing 14 protrude from the wall of the air inlet cavity 11, forming a mounting area 8 between the bottom housing 14 and the lower end wall of the air outlet cavity 12. The pressurization structure 3 is located on the mounting area 8.

[0043] like Figure 1 and Figure 2As shown, in terms of specific structural design, to maximize the intake air volume, the fan structure 21 is made relatively large. Therefore, it's easy to see that the horizontal extension length of the fan structure 21 is relatively long, resulting in one end of the air outlet cavity 12 protruding beyond one end of the air inlet cavity 11. To improve the installation and fixation effect of the booster structure 3, one end of the bottom shell also protrudes beyond the outer wall of the air inlet cavity 11, forming an installation area 8 between the shell and the lower end wall of the air outlet cavity 12. During installation, the booster structure 3 is essentially recessed and installed on the first shell 1. This semi-enclosed installation further enhances the overall structural strength of the vehicle air conditioning structure 100. In actual installation, the booster structure 3 can be configured as a fan structure component.

[0044] A second shell 4 is provided on the installation area 8, and the second shell 4 is connected to the first shell 1. The pressurizing structure 3 is disposed on the second shell 4. Specifically, when installing the pressurizing structure 3, the second shell 4 is installed on the outside of the pressurizing structure 3. The second shell 4 is sealed at the junction of the installation area 8, the first shell 1, and the bottom shell to prevent airflow entering the second shell 4 from leaking out from its installation junction, thereby ensuring the air intake effect of the air intake chamber. The second shell 4 and the first shell 1 can be configured as separate structures. During installation, they can be installed using screws and sealing strips. Preferably, the outer end face of the second shell 4 needs to maintain a certain degree of close contact with the bottom shell, the outer wall of the air intake chamber 11, and the outer wall of the air outlet chamber 12, thereby improving the stability and consistency of the entire shell structure and effectively ensuring the overall strength of the shell structure under the high-frequency vibration environment of vehicle operation.

[0045] As described above, the air intake end of the booster structure 3 is positioned in the direction of the front of the vehicle. Typically, to ensure the cleanliness of the intake air, a corresponding filter structure is installed at the end of the air intake structure. Specifically, the second housing 4 is provided with an air intake pipe 41, the input end of the booster structure 3 corresponds to the air intake pipe 41, and a filter element 42 is provided on the end of the air intake pipe 41 away from the second housing 4 for purifying the intake air.

[0046] During installation, the end of the air intake pipe 41 is installed inside the front bumper of the vehicle structure. The outer end face of the filter element 42 is the windward side. During actual vehicle operation, the airflow passes through the filter element 42 to filter out most of the solid particles in the air, and the relatively clean air enters the vehicle body through the air intake 13 and the aforementioned external circulation air path.

[0047] Filtered outside air typically needs to be diverted before entering the vehicle interior to ensure even airflow distribution to multiple locations within the vehicle, thereby improving passenger comfort. Therefore, in this embodiment, the first housing 1 further includes an air outlet housing 5, which is located at the air outlet and has multiple air guides 51 for connecting to the vehicle's driver's cabin.

[0048] In the specific process of air guidance, as described above, external air moves to the air outlet under the drive of the fan structure 21. The air outlet is connected to the air outlet shell 5. The air entering the air outlet shell 5 is guided to multiple internal air outlet structures inside the vehicle structure through multiple air guides 51, thereby forming airflow at different air outlet positions inside the vehicle to meet different needs during vehicle operation.

[0049] Specifically, the fan structure 21 includes an evaporator fan, which is installed inside the air outlet cavity 12. The air inlet 13 and air outlet of the evaporator fan are respectively provided corresponding to the air inlet cavity 11 and the air outlet. During operation, the evaporator fan can drive air to flow from the air inlet cavity 11 to the air outlet cavity 12, thereby forming corresponding external circulation air path and internal circulation air path.

[0050] Specifically, an external circulation damper 6 is provided on the first shell 1 at the position corresponding to the air inlet 13 to control the air intake flow of the air inlet 13; an internal circulation air inlet 7 is also provided on the rear end wall of the first shell 1 corresponding to the air intake cavity 11 to connect to the vehicle cabin.

[0051] like Figure 2 , Figure 3 and Figure 4As shown, corresponding to the external circulation air path, the opening degree of the circulation damper can adjust the air intake volume. In actual implementation, the circulation damper can be connected to the corresponding drive structure for automatic control. For the pressurization structure 3, after meeting the requirements for rapid defrosting and cooling, the pressurization structure 3 can increase the air pressure inside the vehicle, thereby minimizing the pressure of the airflow on the circulation damper and also extending the service life of the circulation damper to a certain extent. When corresponding to the internal circulation air path, the circulation damper is in the closed state. During the operation of the evaporator fan, the internal air of the vehicle circulates between the internal circulation vent 7 and the air outlet shell 5.

[0052] The evaporator assembly 22 includes a heat dissipation tank 221 and an evaporator core 222. The heat dissipation tank 221 is installed in the air inlet chamber 11, and the evaporator core 222 is installed in the air inlet chamber 11 at the end of the heat dissipation tank 221 away from the air outlet chamber 12. The evaporator core 222 is connected to the heat dissipation tank 221 for heat exchange with the heat dissipation tank 221.

[0053] The evaporator core 222 is connected to the heat dissipation tank 221. During the operation of the entire air conditioning structure, when the evaporator core 222 starts working, it can perform efficient heat exchange with the heat dissipation tank 221, thereby promoting the reduction of the temperature of the coolant inside the heat dissipation tank. When the temperature of the tank decreases, it can further reduce the temperature of the air in the environment.

[0054] In order to improve the cooling effect of the heat dissipation tank 221 and the evaporator core 222, in this embodiment, the heat dissipation tank 221 and the evaporator core 222 are both installed at an angle in the air inlet cavity 11; in the direction from the front to the rear of the air inlet cavity 11, the heat dissipation tank 221 and the evaporator core 222 are installed at an angle from bottom to top.

[0055] The tilted installation of the radiator tank structure further increases the contact area between the tank structure and the air, thereby improving the heat exchange effect. Specifically, the tank structure typically includes multiple heat dissipation flat tubes. When air passes through the gaps between these tubes, it can efficiently exchange heat with the water within them. In this embodiment, the tilted installation of the radiator tank 221 enhances the contact effect between the heat dissipation flat tubes and the air, resulting in a better cooling effect for the entire air conditioning structure.

[0056] This utility model also includes a car, which includes a vehicle air conditioning structure 100. The specific solution of the vehicle air conditioning structure 100 is as described in the above embodiments. Since the vehicle air conditioning structure 100 applies all the technical solutions in the above embodiments, it also has all the beneficial effects of the above embodiments, and will not be described in detail here.

[0057] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
