Description

Technical Field

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

[0002] As a key component of the air conditioning system, the performance of the vehicle's air conditioning condenser directly affects the cooling effect of the entire air conditioning system and the vehicle's energy consumption.

[0003] In the traditional design of vehicle air conditioning condensers, the structural support structure of some condensers is not stable enough. As a result, during vehicle operation, due to factors such as vibration and bumps, internal components are prone to displacement and loosening, which affects the normal operation of the condenser, or even causes component damage, shortens the service life of the condenser, and increases maintenance costs.

[0004] In terms of heat exchange efficiency, early condenser designs suffered from uneven refrigerant distribution, resulting in insufficient heat exchange in some areas and poor cooling performance. At the same time, the limited heat dissipation area and the unreasonable design of the heat dissipation components made it difficult to quickly and effectively dissipate the heat of the high-temperature refrigerant. This caused the air conditioning system to consume more energy to maintain cooling, which not only increased the vehicle's energy consumption but also reduced energy utilization efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of unstable structural support of traditional vehicle air conditioner condensers, which are prone to displacement and loosening of internal components due to vibration and bumps during vehicle operation, resulting in component damage, shortened life and increased maintenance costs. In terms of heat exchange efficiency, the refrigerant distribution is uneven, the heat dissipation area is limited and the component design is unreasonable, resulting in poor cooling, increased energy consumption and reduced energy utilization efficiency. This utility model provides a vehicle air conditioner condenser core assembly.

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

[0007] A vehicle air conditioner condenser core includes a combined pressure plate, which is arranged in two sets, left and right. A channel flat tube runs through the two sets of combined pressure plates. A heat dissipation assembly is sleeved on the outside of the channel flat tube. The heat dissipation assembly includes a sleeve, a heat dissipation fin, and fins. The sleeve passes through the side wall of the heat dissipation fin. The inner end of the fin is fixedly connected to the outer side wall of the heat dissipation fin. A water inlet pipe and a water outlet pipe are arranged on the right side of the channel flat tube. A mounting cover is sleeved on the outside of the combined pressure plate, the channel flat tube, the heat dissipation assembly, and the water inlet pipe. The channel flat tube is arranged in multiple rows in parallel. A manifold is fixedly connected on both sides of the channel flat tube. Protective components are arranged above and below the heat dissipation assembly. The two ends of the protective components pass through the two ends of the combined pressure plate.

[0008] Furthermore, the two sets of combined pressure plates are located on both sides of the heat dissipation assembly. The side wall of the channel flat tube penetrates the inner side of the sleeve and the heat dissipation fin. When the refrigerant flows in the channel flat tube, the heat dissipation assembly begins to function. Outside air enters the condenser core through the heat dissipation hole on the back side of the mounting cover and exchanges heat with the channel flat tube and the heat dissipation assembly on its outer side.

[0009] Furthermore, the water inlet pipe is located above the drain pipe, and the left ends of the water inlet pipe and the drain pipe are respectively fixedly connected to the upper and lower ends of the right end of the channel flat tube. After heat exchange, the refrigerant is cooled into a liquid state, flows through the channel flat tube to the lower end of the right end, and is discharged from the drain pipe from the condenser core.

[0010] Furthermore, the rear ends of the water inlet pipe and the drain pipe penetrate the rear side wall of the mounting cover. The rear side of the mounting cover is provided with heat dissipation holes, and a protective cover is movably installed on the front side of the mounting cover. The function of the manifold is to evenly distribute the refrigerant flowing from the water inlet pipe into each row of flat channel pipes, ensuring that the refrigerant can flow relatively evenly within the entire condenser core.

[0011] Furthermore, the protective component includes a connecting rod and a side plate. The connecting rod and the side plate are located above and below the heat dissipation component in sets. The two ends of the upper and lower sets of connecting rods respectively penetrate the upper and lower side walls of the combined pressure plate, and the outer side of the connecting rod penetrates the inner side of the side plate, thereby fixing and protecting the heat dissipation component.

[0012] Furthermore, the outer side of the connecting rod penetrates the inner side of the side plate, and the outer surface of the side plate is provided with an anti-corrosion coating, which can prevent the side plate from being corroded and extend the service life of the condenser core.

[0013] Furthermore, the outer side of the connecting rod penetrates the inner side of the side plate, and the outer surface of the side plate is provided with an anti-corrosion coating, which is a galvanized layer or an electrophoretic paint layer. The two ends of the upper and lower sets of connecting rods respectively penetrate the upper and lower side walls of the combined pressure plate, and the outer side of the connecting rod penetrates the inner side of the side plate.

[0014] Furthermore, the channel flat tube, heat dissipation components, and manifold are all made of aluminum alloy, which not only ensures the stability of the structure but also prevents dust and other impurities from entering and affecting the heat exchange effect to a certain extent.

[0015] Compared with the prior art, this utility model provides a vehicle air conditioner condenser core, which has the following beneficial effects:

[0016] This vehicle air conditioning condenser core features a structural design with two sets of combined pressure plates that stably support multiple rows of parallel channel flat tubes running through it, ensuring the overall structural stability. The manifolds connected to both sides of the channel flat tubes evenly distribute the refrigerant, effectively improving heat exchange efficiency. In the heat dissipation assembly, sleeves penetrate the heat sink fins, and combined with the outer fins, significantly increasing the heat dissipation area and enhancing the cooling effect, allowing for rapid cooling of high-temperature refrigerant. The protective components, located above and below the heat dissipation assembly, not only stabilize the internal structure through connecting rods and side plates, but the anti-corrosion coating on the side plates also extends service life. The inlet and outlet pipes are located on the right side of the channel flat tubes, a reasonable layout that facilitates refrigerant entry and exit. The rear cover encloses the main components, protecting the internal structure and ensuring airtightness; its ventilation holes promote airflow and improve heat dissipation efficiency. Overall, this condenser core is compact, efficient, and durable, effectively ensuring the stable operation of the vehicle air conditioning system, reducing energy consumption, and creating a comfortable environment inside the vehicle.

[0024] 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 1:

[0025] like Figures 1-6 As shown, a vehicle air conditioner condenser core includes a combined pressure plate 1, which has two sets, left and right, with a channel flat tube 2 passing through between the two sets of combined pressure plates 1. A heat dissipation component 3 is sleeved on the outside of the channel flat tube 2. A water inlet pipe 4 and a drain pipe 5 are arranged on the right side of the channel flat tube 2, with the water inlet pipe 4 located above the drain pipe 5. The left ends of the water inlet pipe 4 and the drain pipe 5 are respectively fixedly connected to the upper and lower ends of the right end of the channel flat tube 2. A mounting cover 6 is sleeved on the outside of the combined pressure plate 1, the channel flat tube 2, the heat dissipation component 3, and the water inlet pipe 4. The rear ends of the water inlet pipe 4 and the drain pipe 5 pass through the rear side wall of the mounting cover 6. A heat dissipation hole 7 is provided on the rear side of the mounting cover 6. A protective cover 8 is movably installed on the front side of the mounting cover 6. The channel flat tube 2 has multiple rows arranged in parallel. A collector pipe 9 is fixedly connected on both sides of the channel flat tube 2. A protective component 10 is arranged above and below the heat dissipation component 3. The two ends of the protective component 10 pass through the two ends of the combined pressure plate 1.

[0026] like Figures 4-6 As shown, the heat dissipation assembly 3 includes a sleeve 31, a heat sink 32, and fins 33. The sleeve 31 penetrates the side wall of the heat sink 32, and the inner end of the fin 33 is fixedly connected to the outer side wall of the heat sink 32. Two sets of combined pressure plates 1 are located on both sides of the heat dissipation assembly 3. The side wall of the channel flat tube 2 penetrates the inner side of the sleeve 31 and the heat sink 32. The high-temperature refrigerant transfers heat to the heat sink 32 and the fins 33, and then they dissipate the heat into the surrounding air, thereby gradually reducing the temperature of the refrigerant and changing it from a gaseous state to a liquid state. Example 2:

[0027] like Figure 4 As shown, the protective component 10 includes a connecting rod 101 and a side plate 102. The connecting rod 101 and the side plate 102 are located above and below the heat dissipation component 3, respectively. The two ends of the two sets of connecting rods 101 pass through the upper and lower side walls of the combined pressure plate 1, respectively. The outer side of the connecting rod 101 passes through the inner side of the side plate 102. The protective component 10 is located above and below the heat dissipation component 3, including the connecting rod 101 and the side plate 102. The two ends of the two sets of connecting rods 101 pass through the upper and lower side walls of the combined pressure plate 1, respectively. The outer side of the connecting rod 101 passes through the inner side of the side plate 102, which serves to fix and protect the heat dissipation component 3 and prevent it from being damaged by vibration or collision during vehicle operation.

[0028] The outer side of the connecting rod 101 penetrates the inner side of the side plate 102. The outer surface of the side plate 102 is provided with an anti-corrosion coating, which is a zinc plating layer or an electrophoretic paint layer, which can prevent the side plate 102 from being corroded and extend the service life of the condenser core.

[0029] Among them, the channel flat tube 2, heat dissipation component 3, and manifold 9 are all made of aluminum alloy.

[0030] Working principle: such as Figures 1-6 As shown, the refrigerant enters and is distributed as follows: high-temperature and high-pressure gaseous refrigerant enters the condenser core from the water inlet pipe 4; the water inlet pipe 4 is fixedly connected to the upper right end of the channel flat pipe 2, and the refrigerant flows into the channel flat pipe 2 from there.

[0031] The channel flat tube 2 is arranged in multiple rows in parallel, and each side is fixedly connected to a manifold 9. The function of the manifold 9 is to evenly distribute the refrigerant flowing from the water inlet pipe 4 into each row of channel flat tubes 2, so as to ensure that the refrigerant can flow relatively evenly in the entire condenser core, and prepare for subsequent heat exchange.

[0032] Heat exchange process: When the refrigerant flows in the channel flat tube 2, the heat dissipation component 3 begins to function. Outside air enters the condenser core through the heat dissipation hole 7 on the rear side of the mounting cover 6 and exchanges heat with the channel flat tube 2 and the heat dissipation component 3 on its outer side. The high-temperature refrigerant transfers heat to the heat sink 32 and fins 33, which then dissipate the heat to the surrounding air, thereby gradually reducing the temperature of the refrigerant and changing it from a gaseous state to a liquid state.

[0033] Refrigerant discharge: After heat exchange, the refrigerant is cooled into liquid state and flows through the flat tube 2 to the lower right end, and is discharged from the drain pipe 5 from the condenser core to continue to circulate in the vehicle air conditioning system to achieve a continuous cooling effect.

[0034] Protection and stabilization function: The protective component 10 is located above and below the heat dissipation component 3, including connecting rod 101 and side plate 102. The two ends of the upper and lower connecting rods 101 pass through the upper and lower side walls of the combined pressure plate 1 respectively. The outer side of the connecting rod 101 passes through the inner side of the side plate 102, which serves to fix and protect the heat dissipation component 3 and prevent it from being damaged by vibration or collision during vehicle operation.

[0035] The outer surface of the side plate 102 is provided with an anti-corrosion coating (galvanized layer or electrophoretic paint layer), which can prevent the side plate 102 from being corroded and extend the service life of the condenser core.

[0036] The combined pressure plate 1 provides support and fixation for the entire condenser core structure. The rear cover 6 encloses the combined pressure plate 1, channel flat tube 2, heat dissipation assembly 3, and water inlet pipe 4 inside, which not only ensures the stability of the structure but also prevents dust and other impurities from entering and affecting the heat exchange effect to a certain extent. At the same time, the protective cover 8 that is movably installed on the front side of the rear cover 6 can further protect the internal components.
