Description

Technical Field

[0001] This utility model relates to the field of condenser manifold technology, specifically a parallel flow condenser manifold for vehicle air conditioning. Background Technology

[0002] As a crucial component of the air conditioning system, the parallel flow condenser manifold of the vehicle air conditioner undertakes the critical task of transporting and distributing refrigerant. Its performance directly affects the cooling effect, energy consumption, and stability of the entire air conditioning system.

[0003] Traditional manifolds have a relatively simple structural design, lacking effective buffer components at both ends of the main pipe. This makes them unable to effectively buffer pressure shocks and vibrations when the refrigerant flows at high speeds. Bumps, acceleration, and deceleration during vehicle operation exacerbate refrigerant pressure fluctuations. This not only easily leads to fatigue damage to the manifold itself, such as pipe ruptures and loose connections, but also affects the stability of the entire air conditioning system. Frequent malfunctions increase maintenance and time costs.

[0005] The purpose of this utility model is to address the shortcomings of existing parallel flow condenser manifolds for vehicle air conditioning in terms of structural stability and refrigerant flow resistance, which fail to meet the demands of modern automobiles for efficient, stable, and energy-saving vehicle air conditioning systems. This utility model provides a parallel flow condenser manifold for vehicle air conditioning.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A parallel flow condenser manifold for vehicle air conditioning includes a main body with buffer components at both ends. Multiple sets of buffer components are arranged vertically on the main body and at different heights. A curved pipe is fixedly connected to the outer end of each buffer component away from the main body. An inlet pipe is fixedly connected to the right end of the top right buffer component, and an outlet pipe is fixedly connected to the right end of the bottom right buffer component. A pressure box is fixedly connected to the left end of the inlet pipe at the left end of the main body. An adsorption component and a pushing component are connected through the side wall of the pressure box. The adsorption component includes a linear motor and a piston plate, with the output end of the linear motor fixedly connected to the side wall of the piston plate. The pushing component includes a linear motor and a piston plate, with the output end of the linear motor movably connected to the side wall surface of the piston plate. The inner ends of the adsorption component and the pushing component penetrate the interior of the pressure box and are slidably connected therein. An E-shaped partition is provided in the center of the pressure box, with the adsorption component and the pushing component located on the front and rear sides of the E-shaped partition, respectively.

[0008] Furthermore, the buffer assembly includes a folded tube, a connecting plate, and a telescopic assembly. The outer end of the folded tube is connected to the side end of the curved tube, and the inner end of the folded tube is connected to the outer end of the main tube. The outer side of the connecting plate is fixedly connected to the inner sidewall of the main tube. The right end of the telescopic assembly is inserted into the inner sidewall of the curved tube. The telescopic frame and the movable rod in the telescopic assembly cooperate with each other to further enhance the telescopic capability of the buffer assembly.

[0009] Furthermore, the inner end of the connecting plate is slidably connected to the inner wall of the folded tube, and the outer end of the telescopic component is rotatably connected to the inner wall of the connecting plate. The connecting plate is fixed to the inner wall of the main tube on one hand, and slides on the inner wall of the folded tube on the other hand.

[0010] Furthermore, the telescopic assembly includes a telescopic frame and a movable rod, with the inner end of the movable rod rotatably connected to the outer right end of the telescopic frame. The telescopic frame and the movable rod in the telescopic assembly cooperate with each other, further enhancing the telescopic capability of the buffer assembly.

[0011] Furthermore, the side wall of the linear motor is slidably connected to the inner side wall of the pressure box, and the inner side of the linear motor is slidably connected to the rear side of the E-shaped partition. When the linear motor in the adsorption assembly is working, it pushes the piston plate to slide inside the pressure box.

[0012] Furthermore, the outer end of the piston plate two is slidably connected to the inner front end of the pressure box, and the rear side of the piston plate two is slidably connected to the front side of the E-shaped partition. The linear motor two in the pushing assembly works to push the piston plate two to move forward in the pressure box.

[0013] Furthermore, a mounting bracket is fixedly installed on the middle of the side wall of the main body for securely installing the manifold at the corresponding position of the vehicle air conditioning system.

[0014] Compared with the prior art, this utility model provides a parallel flow condenser manifold for vehicle air conditioning, which has the following beneficial effects:

[0015] This vehicle air conditioning parallel flow condenser manifold, through its structural design, including buffer components at the left and right ends of the main pipe and multiple sets of components at the top and bottom, effectively buffers the pressure impact and vibration generated during refrigerant flow. This prevents damage to the manifold and the entire air conditioning system caused by pressure fluctuations, ensuring stable system operation. The curved pipe connects the buffer components to the main pipe, optimizing the refrigerant flow path and reducing flow resistance. In terms of pressure regulation, the pressure box and its internal adsorption and pushing components work in perfect harmony. Linear motor one drives piston plate one, and linear motor two drives piston plate two. Using the E-shaped baffle as a boundary, precise regulation of the refrigerant pressure within the main pipe is achieved. When the pressure is too high, the adsorption component adsorbs excess refrigerant; when the pressure is insufficient, the pushing component pushes the refrigerant back into the main pipe, maintaining stable system pressure, ensuring efficient operation of the vehicle air conditioning system, and reducing energy consumption. Overall, this significantly improves the performance and stability of the vehicle air conditioning condenser, extends equipment lifespan, and reduces maintenance costs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0023] like Figures 1-5 As shown, a parallel flow condenser manifold for vehicle air conditioning includes a main body 1. Buffer components 2 are provided at both the left and right ends of the main body 1. Multiple sets of buffer components 2 are provided on the main body 1 and the upper and lower ends. A curved pipe 4 is fixedly connected to the outer end of the buffer component 2 away from the main body 1. An inlet pipe 3 is fixedly connected to the right end of the top right buffer component 2, and an outlet pipe 5 is fixedly connected to the right end of the bottom right buffer component 2. A pressure box 6 is fixedly connected to the left end of the inlet pipe 3 located at the left end of the entire main body 1. An adsorption component 7 and a pushing component 9 are connected through the side wall of the pressure box 6. The inner ends of the adsorption component 7 and the pushing component 9 penetrate the interior of the pressure box 6 and are slidably connected to the interior of the pressure box 6. An E-shaped partition 8 is provided in the middle of the interior of the pressure box 6. The adsorption component 7 and the pushing component 9 are located on the front and rear sides of the E-shaped partition 8, respectively. A mounting bracket 10 is fixedly installed in the middle of the side wall of the main body 1.

[0024] like Figure 2 and Figure 3 As shown, the buffer assembly 2 includes a folded tube 21, a connecting plate 22, and a telescopic assembly 23. The outer end of the folded tube 21 is connected to the side end of the curved tube 4, and the inner end of the folded tube 21 is connected to the outer end of the main tube 1. The outer side of the connecting plate 22 is fixedly connected to the inner wall of the main tube 1. The right end of the telescopic assembly 23 is inserted into the inner wall of the curved tube 4. The inner end of the connecting plate 22 is slidably connected to the inner wall of the folded tube 21, and the outer end of the telescopic assembly 23 is rotatably connected to the inner wall of the connecting plate 22. The telescopic assembly 23 includes a telescopic frame 231 and a movable... The inner end of the movable rod 232 is rotatably connected to the outer right end of the telescopic frame 231. The buffer assembly 2 can effectively alleviate the pressure shock and vibration during the refrigerant flow process. The telescopic frame 231 and the movable rod 232 in the telescopic assembly 23 cooperate with each other to further enhance the telescopic capacity of the buffer assembly 2. When the pressure changes, the telescopic frame 231 extends or retracts, and the movable rod 232 rotates accordingly, so that the entire buffer assembly 2 can better adapt to the pressure fluctuation of the refrigerant and protect the manifold and other components of the vehicle air conditioning system from damage.

[0025] like Figure 4 and Figure 5As shown, the adsorption assembly 7 includes a linear motor 71 and a piston plate 72. The output end of the linear motor 71 is fixedly connected to the side wall of the piston plate 72. The side wall of the linear motor 71 is slidably connected to the inner side wall of the pressure box 6. The inner side of the linear motor 71 is slidably connected to the rear side of the E-type partition 8. When the linear motor 71 in the adsorption assembly 7 is working, it pushes the piston plate 72 to slide within the pressure box 6. When the piston plate 72 moves outward, it can adsorb excess refrigerant in the main body 1 to prevent excessive pressure.

[0026] like Figure 4 and Figure 5 As shown, the pushing assembly 9 includes a linear motor 91 and a piston plate 92. The output end of the linear motor 91 is movably connected to the side wall surface of the piston plate 92. The outer end of the piston plate 92 is slidably connected to the inner front end of the pressure box 6. The rear side of the piston plate 92 is slidably connected to the front side of the E-type partition 8. When the linear motor 91 in the pushing assembly 9 is working, it pushes the piston plate 92 forward in the pressure box 6, pushing the refrigerant in front of the E-type partition 8 back to the main pipe 1, maintaining the stable flow and appropriate pressure of the refrigerant.

[0027] Working principle: such as Figures 1-5 As shown, the refrigerant input and output are as follows: High-temperature and high-pressure gaseous refrigerant enters from the inlet pipe 3, which is connected to the buffer assembly 2 at the top right. The refrigerant flows into the main pipe 1 through the buffer assembly 2. In the main pipe 1, the refrigerant undergoes heat exchange through multiple sets of vertically arranged main pipes 1 and buffer assemblies 2. After the heat exchange is completed, low-temperature and low-pressure liquid refrigerant flows out of the manifold through the outlet pipe 5 from the buffer assembly 2 at the bottom right, and continues to circulate in the vehicle air conditioning system.

[0028] Pressure regulation mechanism: Pressure box 6 plays a key role in pressure regulation; linear motor 71 in adsorption assembly 7 operates, pushing piston plate 72 to slide within pressure box 6; when piston plate 72 moves outward, it can adsorb excess refrigerant in main pipe 1, preventing excessive pressure; the refrigerant pulled outward from piston plate 72 is pushed through the E-shaped opening gap at the outer end of E-shaped partition 8 to the inside of push assembly 9, where linear motor 91 in push assembly 9 operates, pushing piston plate 92 forward within pressure box 6, pushing the refrigerant in front of E-shaped partition 8 back to main pipe 1, maintaining stable refrigerant flow and appropriate pressure; this pressure regulation mechanism ensures the stable operation of the vehicle air conditioning system and avoids malfunctions caused by abnormal pressure;

[0029] Buffer protection function: The buffer assembly 2 can effectively mitigate pressure shocks and vibrations during refrigerant flow; when refrigerant flows into or out of the main pipe 1, the folded pipe 21 can expand and contract according to pressure changes to absorb pressure shocks; the connecting plate 22 is fixed to the inner wall of the main pipe 1 on one hand, and slides on the inner wall of the folded pipe 21 on the other hand, playing an auxiliary support and guiding role; the telescopic frame 231 and the movable rod 232 in the telescopic assembly 23 cooperate with each other to further enhance the telescopic capacity of the buffer assembly 2; when the pressure changes, the telescopic frame 231 expands or contracts, and the movable rod 232 rotates accordingly, so that the entire buffer assembly 2 can better adapt to the pressure fluctuations of the refrigerant and protect the manifold and other components of the vehicle air conditioning system from damage;

[0030] Installation and Fixing: The mounting bracket 10 is fixed to the middle of the side wall of the main pipe 1 to securely install the manifold in the corresponding position of the vehicle air conditioning system, ensuring that it remains stable during vehicle operation without displacement or shaking, and ensuring the normal operation of the manifold.
