Description

Technical Field

[0001] This invention belongs to the field of condenser technology, and specifically discloses an automotive air conditioning condenser and its process. Background Technology

[0002] The automotive air conditioning condenser is a key heat exchange component in the automotive air conditioning system. Its function is to condense the high-temperature, high-pressure refrigerant gas discharged from the compressor into a liquid and dissipate the heat to the outside environment. The heat dissipation performance of the condenser directly affects the cooling efficiency of the automotive air conditioning system, the power consumption of the compressor, and the overall fuel economy of the vehicle.

[0003] Traditional automotive air conditioning condensers typically employ a tube-fin or tube-strip structure, with refrigerant flowing inside the tubes and air flowing outside, exchanging heat through the cooling fins. As the automotive industry's demands for lightweight design and efficient heat exchange continue to increase, parallel-flow condensers are gradually becoming the mainstream technology. However, existing condensers still present the following technical challenges in design and use:

[0004] First, heat dissipation efficiency needs further improvement. The core structure of traditional condensers typically consists of bent heat dissipation fins welded between flat tubes. This structure not only involves complex assembly processes but also results in poor uniformity of airflow contact with the heat exchange surface, leading to insufficient localized heat transfer. Furthermore, the surfaces of the condenser tubes are mostly smooth, making it difficult for effective turbulence to form as airflow passes through, resulting in a thicker boundary layer and limiting the improvement of the convective heat transfer coefficient.

[0005] Second, uneven airflow distribution affects heat exchange performance. In practical vehicle applications, condensers are typically installed at the front of the car. Due to the presence of structures such as the front bumper and anti-collision beam, the airflow distribution on the condenser's windward side is uneven. Studies show that uneven intake air velocity significantly reduces the condenser's heat exchange performance. Existing condenser designs are mostly based on the assumption of uniform intake airflow, lacking active airflow guidance and regulation structures, making it difficult to fully realize the heat dissipation potential.

[0006] Third, the intrusion of debris can easily cause blockages or damage. During vehicle operation, the condenser directly faces the airflow from the front of the vehicle. Insects, sand, poplar catkins, and other debris are easily carried in by the airflow and can adhere to or impact the condenser's cooling fins. Long-term accumulation can lead to blockage of the cooling channels, increased ventilation resistance, and in severe cases, even deformation and damage to the fins, directly affecting the condenser's heat dissipation capacity and the cooling effect of the air conditioning system. This problem is particularly prominent in areas with abundant poplar catkins in spring or in environments with poor road conditions.

[0007] Fourth, the integration of existing protective and heat dissipation structures is low. Although some condensers are equipped with protective grilles or filters, these are mostly independent add-ons with weak integration with the condenser body. They only have a single physical interception function and fail to organically combine protection and heat dissipation enhancement. In addition, the ease of cleaning the protective structure itself is often overlooked; once debris adheres, it is difficult to wash off, increasing maintenance difficulty.

[0008] To address the aforementioned issues, it is necessary to develop a novel automotive air conditioning condenser structure. By optimizing airflow organization, enhancing the turbulence effect of the heat exchange surface, and integrating protection and heat dissipation functions, this structure can effectively resist the intrusion of debris while improving heat exchange efficiency and ensuring ease of cleaning and maintenance. Summary of the Invention

[0009] In view of this, the purpose of this invention is to provide an automotive air conditioning condenser and process to solve the problems mentioned above.

[0010] To achieve the above objectives, the present invention provides an automotive air conditioning condenser, including a condensing component. The condensing component includes multiple vertically distributed condensing tubes. Multiple guide grooves are provided on the top and bottom surfaces of the condensing tubes. The guide grooves regularly disturb the airflow in contact with the condensing tubes. A liquid inlet groove and a drain groove are provided on the condensing tubes, and a flow guiding channel is provided between the liquid inlet groove and the drain groove.

[0011] A heat-conducting block is fitted inside the condenser tube on the outside of the flow channel. The heat-conducting block is used to transfer the heat on the flow channel to the condenser tube. Multiple heat dissipation fins are arranged side by side between two adjacent condenser tubes, and a diffuser is fixed between two adjacent heat dissipation fins.

[0012] In the above technical solution, the heat dissipation fin plate has a V-shaped cross-section, and an air intake channel is provided between two adjacent heat dissipation fin plates. The receiving end of the air intake channel is larger than the exhaust end of the air intake channel, and the diffuser is distributed in the air intake channel.

[0013] In the above technical solution, the condenser further includes an inlet pipe and an outlet pipe, and a plurality of condenser pipes are fixed between the inlet pipe and the outlet pipe. The upper condenser pipes are inclined downwards, and the lower condenser pipes are inclined upwards.

[0014] In the above technical solution, furthermore, a rib ring is distributed between the two condenser tubes, and the rib ring is fixed to the rear of the heat dissipation rib plate to enhance the strength of the fixation between the heat dissipation rib plate and the condenser tubes.

[0015] In the above technical solution, a protective grille is further provided on the front side of the condenser tube. One side of the protective grille is fixed to the liquid inlet pipe, and the other side of the protective grille is fixed to the liquid outlet pipe. The protective grille uniformly conducts the airflow to the condenser tube.

[0016] In the above technical solution, the diffuser further includes mounting posts distributed inside the rib ring, the rib ring is a conical ring, the front end of the mounting post is spherical, and the axis of the mounting post coincides with the axis of the rib ring.

[0017] In the above technical solution, further, the outer wall of the mounting column is provided with a plurality of fins distributed from front to back, the fins being evenly spaced around the axis of the mounting column, and the fins on the mounting column being inclined backward.

[0018] In the above technical solution, the fins are elongated, and the fins at the front of the mounting post are shorter than the fins at the rear of the mounting post.

[0019] In the above technical solution, the fins located at the rear are further fixed to the rib ring, the air inlet of the rib ring is larger than the air outlet of the rib ring, and the air inlet end of the rib ring is inclined downward.

[0020] An automotive air conditioning condensation process includes the following steps:

[0021] Step 1, Installation: Connect the inlet end of the liquid inlet pipe to the compressor, and connect the outlet end of the liquid outlet pipe to the throttling device, while ensuring that the air inlet end of the rib ring faces the car's air intake grille.

[0022] Step two, heat dissipation: When the compressor drives the high-temperature, high-pressure refrigerant into the interior of the condenser, the impact airflow from the car will penetrate the protective grille and contact the condenser. At the same time, the guide groove will disturb the airflow on the condenser, thereby achieving rapid heat dissipation from the surface of the condenser.

[0023] Step 3, heat diffusion: When high-temperature and high-pressure refrigerant flows into the inside of the liquid inlet tank, the refrigerant will enter the inside of the discharge tank through the guide channel. Since the inner diameter of the guide channel is smaller than the inner diameter of the liquid inlet tank, the refrigerant will evenly contact the inner wall of the guide channel, so that the heat of the inner wall of the refrigerant can be fully transferred to the guide channel, thereby achieving rapid cooling of the heat inside the guide channel.

[0024] Step four, protection: When the airflow from a vehicle impact passes through the protective grille, the grille can intercept large particles in the airflow. The airflow that intercepts large particles will pass through the rib ring, and the fins will intercept the particles in the airflow again, preventing the particles in the airflow from contacting the cooling fan inside the car.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This invention significantly improves heat exchange efficiency by optimizing the surface structure and internal heat conduction path of the condenser tube. Specifically, multiple guide grooves are formed on the top and bottom surfaces of the condenser tube. When airflow passes through, these guide grooves can regularly disturb the airflow boundary layer, disrupt the laminar sublayer, and make the airflow distribution around the condenser tube more uniform, thereby forcing convective heat transfer and accelerating heat dissipation. At the same time, a flow guiding channel is set inside the condenser tube, and a heat-conducting block is sleeved on its outside. When the high-temperature refrigerant flows through the flow guiding channel with a small inner diameter, it can fully contact the inner wall of the channel. Heat is quickly transferred to the heat-conducting block through the flow guiding channel, and then uniformly conducted to the entire condenser tube by the heat-conducting block. This achieves a highly efficient heat conduction path, avoids local overheating, and greatly improves the overall heat dissipation capacity of the condenser.

[0027] 2. This invention effectively solves the problem of uneven airflow on the windward side by setting up a special heat dissipation fin structure. The heat dissipation fin is designed with a V-shaped cross-section and the pointed corners face forward, which creates a trumpet-shaped air intake channel with a large air inlet and a small exhaust outlet between two adjacent heat dissipation fins. This structure can compress and accelerate the incoming airflow, making the airflow faster and with stronger impact when passing through the surface of the condenser tubes. In addition, by tilting the upper condenser tubes downward and the lower condenser tubes upward, a guiding effect is created on the airflow, allowing the airflow after passing through the protective grille to diffuse more quickly and evenly to the surface of all condenser tubes, eliminating airflow dead zones, ensuring that the entire core can participate in efficient heat exchange, and maximizing the utilization efficiency of the heat dissipation area.

[0028] 3. This invention constructs a multi-layered debris interception system consisting of an outer grille and inner fins, effectively solving the problems of debris clogging and damaging the condenser. First, the front protective grille, composed of crisscrossing strips, can initially intercept large particles of debris (such as pebbles and leaves) in the airflow, preventing them from directly impacting or embedding in the radiator fins. Second, the airflow after initial filtration enters the secondary protection zone, which consists of ribs and mounting brackets. Rearwardly inclined fins are distributed on the mounting brackets, which further intercept residual fine debris (such as flying insects and poplar fluff). This dual-protection design significantly reduces the risk of debris entering the car's internal cooling fan or clogging the deep parts of the condenser, ensuring long-term operational reliability.

[0029] 4. This invention highly integrates structural strength, enhanced heat dissipation, and self-cleaning function, resulting in a compact structure that is easy to maintain. On one hand, the rib ring not only serves as the mounting base for the protective structure but also acts as a reinforcing rib, fixed to the rear of the heat dissipation rib plate. This significantly improves the connection strength between the heat dissipation rib plate and the condenser tube, enhancing the overall structure's shock resistance and durability. On the other hand, the fins are designed with a backward-sloping structure of varying lengths. This design not only increases the contact area with airflow to aid heat dissipation but, more importantly, allows the tilted fins to guide the water flow during cleaning (such as rainwater washing or high-pressure water gun cleaning). This allows debris (such as mud, sand, and willow catkins) adhering to the fins to quickly separate and be discharged under gravity and water flow, preventing debris residue and achieving the self-cleaning function of the protective structure. This also improves the portability of cleaning the condenser. Attached Figure Description

[0038] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0040] Example 1: Please refer to Figures 1-8 As shown, the present invention provides a technical solution:

[0041] The present invention is an automotive air conditioning condenser, including a condensing component, which includes multiple vertically distributed condensing tubes 13. Multiple guide grooves 16 are provided on the top and bottom surfaces of the condensing tubes 13. The guide grooves 16 regularly disturb the airflow in contact with the condensing tubes 13. A liquid inlet groove 17 and a drain groove 110 are provided on the condensing tubes 13. A flow guide channel 18 is provided between the liquid inlet groove 17 and the drain groove 110.

[0042] A heat-conducting block 19 is fitted inside the condenser tube 13 outside the flow channel 18. The heat-conducting block 19 is made of a material with good thermal conductivity. The heat-conducting block 19 is used to transfer the heat on the flow channel 18 to the condenser tube 13. Multiple heat dissipation fins 14 are arranged side by side between two adjacent condenser tubes 13. A diffuser is fixed between two adjacent heat dissipation fins 14.

[0043] The heat dissipation fin plate 14 has a V-shaped cross-section, with the sharp corners of the heat dissipation fin plate 14 distributed forward. An air intake channel is provided between two adjacent heat dissipation fin plates 14. The receiving end of the air intake channel is larger than the exhaust end of the air intake channel, and the diffuser is distributed in the air intake channel.

[0044] The air intake channel is the distance between two heat dissipation fins 14. Since both ends of the heat dissipation fins 14 are connected to the condenser pipes 13, the air intake channel has a trumpet-shaped structure.

[0045] The condenser also includes an inlet pipe 1 and a drain pipe 12, with multiple condenser tubes 13 fixed between the inlet pipe 1 and the drain pipe 12. Please refer to the instruction manual appendix. Figure 8 As shown, the upper condenser tube 13 is inclined downwards, and the lower condenser tube 13 is inclined upwards.

[0046] Rib rings 15 are distributed between the two condenser tubes 13. The rib rings 15 are fixed to the rear of the heat dissipation fin plate 14 to strengthen the fixation strength between the heat dissipation fin plate 14 and the condenser tubes 13.

[0047] A protective grille 11 is distributed on the front side of the condenser tube 13. One side of the protective grille 11 is fixed to the liquid inlet pipe 1, and the other side of the protective grille 11 is fixed to the liquid outlet pipe 12. The protective grille 11 evenly conducts the airflow to the condenser tube 13.

[0048] The protective grille 11 includes multiple vertically distributed strip plates and multiple horizontally distributed strip plates. During assembly, the multiple vertically distributed strip plates and multiple horizontally distributed strip plates are cross-fixed. The angle of the strip plates can also be adjusted according to actual needs, so that the airflow from the car impact is evenly conducted to the condenser pipe 13.

[0049] The diffuser includes mounting posts 2 distributed inside the rib ring 15. The rib ring 15 is a conical ring, and the front end of the mounting post 2 is spherical. The axis of the mounting post 2 coincides with the axis of the rib ring 15.

[0050] Multiple fins 21 are distributed sequentially from front to back on the outer wall of the mounting column 2. The fins 21 are evenly spaced around the axis of the mounting column 2, and the fins 21 on the mounting column 2 are tilted backward.

[0051] The fin 21 is long and narrow. The fin 21 at the front of the mounting post 2 is shorter than the fin 21 at the rear of the mounting post 2. The axis of the mounting post 2 coincides with the axis of the rib ring 15.

[0052] The fin 21 located at the rear is fixed to the rib ring 15. The air inlet of the rib ring 15 is larger than the air outlet of the rib ring 15, and the air inlet end of the rib ring 15 is tilted downward.

[0053] In actual use, the staff first fixes the liquid inlet pipe 1 and liquid outlet pipe 12 of the condenser to the car frame. When installing the condenser, it is necessary to ensure that the air inlet of the rib ring 15 faces forward. Then, the protective grille 11 is fixed to the liquid inlet pipe 1 and liquid outlet pipe 12. After the condenser is installed with the car frame, the staff connects the liquid inlet end of the liquid inlet pipe 1 to the compressor and the liquid outlet end of the liquid outlet pipe 12 to the throttling device to complete the installation of the condenser.

[0054] When the car is moving, the airflow from the impact of the car will pass through the protective grille 11 and come into contact with the condenser pipe 13, which can achieve rapid heat dissipation on the condenser pipe 13. The staff can adjust the angle of the strip plate in the protective grille 11 according to actual needs, so that the airflow from the impact of the car can be evenly conducted to the condenser pipe 13.

[0055] When the automotive compressor transports high-temperature, high-pressure refrigerant, the high-temperature, high-pressure refrigerant can enter the interior of the guide channel 18 through the liquid inlet 17. Subsequently, the refrigerant inside the guide channel 18 will pass through the discharge trough 110 and enter the interior of the throttling device, thereby enabling the high-temperature, high-pressure refrigerant to pass through the condenser.

[0056] When the high-temperature, high-pressure cooler passes through the inside of the guide channel 18, the heat of the refrigerant will be discharged into the inside of the heat-conducting block 19 through the guide channel 18. Then the heat-conducting block 19 will drive the heat to be evenly transferred to the condenser tube 13, which can realize that the condenser tube 13 drives the heat in the refrigerant to dissipate into the air.

[0057] When the airflow from the car impact comes into contact with the condenser pipe 13, the guide groove 16 will turbulent the airflow on the condenser pipe 13, thereby allowing the airflow around the condenser pipe 13 to contact the condenser pipe 13 evenly, so that the heat on the condenser pipe 13 can be dissipated quickly.

[0058] During assembly, the upper condenser tube 13 is tilted downwards and the lower condenser tube 13 is tilted upwards. This allows the airflow passing through the protective grille 11 to quickly diffuse onto the condenser tube 13, thus enabling the heat in the refrigerant to dissipate rapidly.

[0059] When the airflow generated by the car collision passes through the protective grille 11, large particles in the airflow can be intercepted by the protective grille 11. The airflow that intercepts large particles will enter the interior of the rib ring 15 under the diversion of the condenser pipe 13. When the airflow enters the interior of the rib ring 15, the airflow can carry away the heat on the heat dissipation rib plate 14, thereby enabling the heat on the heat dissipation rib plate 14 to dissipate quickly.

[0060] When the airflow enters the interior of the rib ring 15, the fins 21 can intercept the impurities in the airflow again, which can prevent the airflow containing impurities from contacting the cooling fan inside the car. Since the fins 21 are fixed to the rib ring 15, and the rib ring 15 is fixed to the condenser tube 13, when the airflow comes into contact with the fins 21, the airflow can carry away the heat on the rib ring 15 and the cooling fin plate 14 through the fins 21.

[0061] It should be noted that the air intake end of the rib ring 15 is tilted downwards, the axis of the mounting post 2 coincides with the axis of the rib ring 15, and the fins 21 are evenly distributed with the axis of the mounting post 2 as the center. The fins 21 on the mounting post 2 are tilted backwards. This can prevent debris in the airflow from easily adhering to the fins 21 when the car hits the airflow. At the same time, it can also make the debris on the fins 21 quickly separate from the fins 21 when the water washes the fins 21, thereby improving the portability of cleaning the condenser.

[0062] Example 2: Please refer to Figures 1-8 As shown, the present invention provides an automotive air conditioning condensation process, comprising the following steps:

[0063] Step 1, Installation: Connect the inlet end of the inlet pipe 1 to the compressor, and connect the outlet end of the outlet pipe 12 to the throttling device, while ensuring that the air inlet end of the rib ring 15 faces the car's air intake grille.

[0064] Step 2, heat dissipation: When the compressor drives the high-temperature and high-pressure refrigerant into the interior of the condenser 13, the impact airflow from the car will pass through the protective grille 11 and come into contact with the condenser 13. At the same time, the guide groove 16 will disturb the airflow on the condenser 13, thereby achieving rapid evaporation of heat from the surface of the condenser 13.

[0065] Step 3, heat diffusion: When high-temperature and high-pressure refrigerant flows into the inside of the liquid inlet tank 17, the refrigerant will enter the inside of the discharge tank 110 through the guide channel 18. Since the inner diameter of the guide channel 18 is smaller than the inner diameter of the liquid inlet tank 17, the refrigerant will evenly contact the inner wall of the guide channel 18, so that the heat of the inner wall of the refrigerant can be fully transferred to the guide channel 18, thereby achieving rapid cooling of the heat inside the guide channel 18.

[0066] Step 4, protection: When the airflow from the vehicle impact passes through the protective grille 11, the protective grille 11 can intercept large particles in the airflow. The airflow that intercepts large particles will pass through the rib ring 15. At this time, the fins 21 will intercept the particles in the airflow again, preventing the particles in the airflow from contacting the cooling fan inside the car.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
