Description

Technical Field

[0001] This invention belongs to the field of condenser technology, and particularly relates to a fast-cooling double-layer automotive air conditioning condenser. Background Technology

[0002] A car's refrigeration system generally consists of a compressor, an expansion throttling device, an evaporator, a dryer, a condenser, a blower, a fan, and a control device. When the refrigeration system is working, the compressor and expansion throttling device work together to evaporate high-temperature gas. The high-temperature gas is then discharged into the condenser, where it is converted back into refrigerant liquid. The heat in the condenser pipes is then rapidly transferred to the air near the pipes, achieving heat exchange with the high-temperature gas.

[0003] Existing automotive double-layer condensers accumulate a large amount of dust on their surface during use, which hinders heat dissipation. To address this technical problem, Chinese patent CN222418046U proposes a design that uses two sets of dust filters to block dust from both sides of the condenser. However, the dust filters themselves also obstruct airflow and contact with the condenser. Furthermore, as dust accumulates, airflow becomes even more limited, reducing the condenser's heat dissipation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a fast-cooling double-layer automotive air conditioning condenser, which aims to solve the technical problem in the prior art where dust clogging the filter components affects airflow, leading to a decrease in the condenser's heat dissipation effect.

[0005] This invention is implemented as follows: a rapid-cooling double-layer automotive air conditioning condenser includes a double-layer condenser body. Mounting plates are fixedly installed on both sides of the double-layer condenser body. Protective filter plates and protective boxes are respectively connected to both ends of the double-layer condenser body. A first filter screen is fixedly installed on the side wall of the protective box. A first fan that blows air onto the double-layer condenser body is fixedly installed inside the protective box. Multiple sets of air inlet chambers are fixedly installed on the protective box. Both ends of the air inlet chambers are open structures. Multiple sets of first guide plates and second guide plates are fixedly installed inside the air inlet chambers, forming an air channel. A horizontal plate is fixedly installed inside the air inlet chamber, and the horizontal plate is fixedly connected to the second guide plate. The horizontal plate and the second guide plate form a return flow cavity. The height of the horizontal plate is lower than the suspended end of the second guide plate. A second filter screen is fixedly installed on the horizontal plate, located in the projection area of ​​the suspended end of the first guide plate onto the horizontal plate. The return flow cavity is connected to the protective box through an air inlet pipe. Multiple sets of second fans are fixedly installed at the air inlet end of the air inlet chamber.

[0006] Further technical solution: Multiple sets of connecting grooves are fixedly installed on the double-layer condenser body. A first connecting plate and a second connecting plate are slidably installed at both ends of the connecting grooves. The first connecting plate is fixedly connected to the protective filter plate, and the second connecting plate is fixedly connected to the protective box. Two sets of fixing screws for fixing the first connecting plate and the second connecting plate are threaded on the connecting grooves.

[0007] A further technical solution: the opening at the air inlet end of the air inlet chamber is larger than the opening at the air outlet end of the air inlet chamber, and the air outlet end of the air inlet chamber corresponds to the first filter screen on the corresponding side wall.

[0008] A further technical solution: multiple sets of spaced partitions are fixedly installed in the air intake chamber, and multiple sets of second fans are distributed in different areas separated by the partitions.

[0009] A further technical solution: the first guide plate is V-shaped, the second guide plate is at an angle to the horizontal plane, and the second guide plate and one side wall of the first guide plate form an air channel.

[0010] Further technical solution: Multiple sets of brackets are fixedly installed on the protective box, and a frame-shaped movable frame is slidably installed on the brackets. A first brush for cleaning the first filter screen is fixedly installed on the side of the protective box near the movable frame. Multiple sets of through slots located between the first brushes are opened on the movable frame. An electric telescopic rod that drives the movable frame to move back and forth is fixedly installed on the protective box.

[0011] Further technical solution: Multiple sets of support plates are fixedly installed on the mobile frame. The support plates are T-shaped and extend into the air inlet chamber. The position of the support plates corresponds to the area separated by the partition. A second brush that contacts the second filter screen is fixedly installed on the support plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The double-layer condenser body is sealed and protected by a protective filter plate and a protective box to prevent dust in the air from directly contacting the heat dissipation fins on the double-layer condenser body. This prevents dust from adhering to the surface of the double-layer condenser body and affecting the heat dissipation effect. In addition, the air can be blown directly from the protective box to the double-layer condenser body without any obstruction, ensuring the heat dissipation effect of the double-layer condenser body.

[0013] 2. When air flows along the second guide plate, the air passage narrows at the end of the second guide plate, increasing the airflow speed. Consequently, the movement speed of dust particles inside the air increases. Under inertia, a large number of dust particles will move directly with the air to the air outlet of the air inlet chamber. Most of the dust particles carried in the air leave the air inlet chamber directly, thereby reducing the number of dust particles that can come into contact with the second filter. This reduces the amount of dust at the air inlet source, further reducing the amount of dust particles adhering to the second filter, ensuring the cleanliness of the second filter, ensuring the air intake, and thus ensuring the cooling effect of the double-layer condenser body.

[0014] 3. Because the airflow is faster and the air pressure is lower at the end of the second guide plate, the airflow speed is lower and the air pressure is higher in the area where the second filter is located. As a result, the dust particles in the area where the second filter is located and the dust particles cleaned off the second filter will be drawn into the fast-flowing air and discharged under the action of air pressure, further reducing the probability of the second filter clogging and ensuring the air intake of the protective box.

[0015] 4. The moving frame is driven to move back and forth by an electric telescopic rod. When the moving frame moves back and forth, the first brush cleans the first filter screen. At the same time, the moving frame drives the second brush through the support plate to further clean the second filter screen. The dust particles cleaned off are blown away by the air, which further ensures the cleanliness of the first and second filters, ensures the air intake of the protective box, and ensures the cooling effect of the double-layer condenser body.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] like Figures 1-7As shown, this invention provides a rapid cooling double-layer automotive air conditioning condenser, comprising a double-layer condenser body 1. Mounting plates 2 are fixedly installed on both sides of the double-layer condenser body 1. Protective filter plates 4 and protective housings 6 are respectively connected to both ends of the double-layer condenser body 1. Multiple sets of connecting grooves 3 are fixedly installed on the double-layer condenser body 1. A first connecting plate 5 and a second connecting plate 7 are slidably installed at both ends of the connecting grooves 3. The first connecting plate 5 is fixedly connected to the protective filter plate 4, and the second connecting plate 7 is fixedly connected to the protective housing 6. Two sets of fixing screws for fixing the first connecting plate 5 and the second connecting plate 7 are threaded onto the connecting grooves 3. A first filter screen 9 is fixedly installed on the side wall of the protective housing 6. A first fan 8, which blows air onto the double-layer condenser body 1, is fixedly installed inside the protective housing 6. Multiple sets of air inlet chambers 10 are fixedly installed on the protective housing 6. Both ends of the air inlet chamber 10 are open structures, with the opening at the air inlet end of the air inlet chamber 10 being larger than the opening at the air outlet end of the air inlet chamber 10. The end corresponds to the first filter screen 9 on the corresponding side wall. Multiple sets of first guide plates 11 and second guide plates 12 are fixedly installed in the air inlet chamber 10. The first guide plate 11 and the second guide plate 12 form an air channel. The first guide plate 11 is V-shaped. The second guide plate 12 is set at an angle with the horizontal plane. The second guide plate 12 and one side wall of the first guide plate 11 form an air channel. A horizontal plate 14 is fixedly installed in the air inlet chamber 10. The horizontal plate 14 is fixedly connected to the second guide plate 12. The horizontal plate 14 and the second guide plate 12 form a return flow. The cavity 13 has a horizontal plate 14 at a height lower than the suspended end of the second guide plate 12. A second filter 15 is fixedly installed on the horizontal plate 14. The second filter 15 is located in the projection area of ​​the suspended end of the first guide plate 11 onto the horizontal plate 14. The return cavity 13 is connected to the protective box 6 through the air inlet pipe 24. Multiple sets of second fans 17 are fixedly installed at the air inlet end of the air inlet chamber 10. Multiple sets of spaced partitions 16 are fixedly installed inside the air inlet chamber 10. The multiple sets of second fans 17 are distributed in different areas separated by the partitions 16.

[0027] In practical application, the double-layer condenser body 1 is fixedly installed in a set position by the mounting plate 2. When in use, the first fan 8 and the second fan 17 are turned on. The rotation of the first fan 8 pushes the air in the protective box 6 to move in the direction of the double-layer condenser body 1. The air comes into contact with the heat dissipation fins of the double-layer condenser body 1 and cools the heat dissipation fins by flowing air. After passing through the double-layer condenser body 1, the air passes through the protective filter plate 4. When the first fan 8 rotates, the outside air can pass through the first filter screen 9 and enter the protective box 6. The air is then blown towards the double-layer condenser body 1 for cooling. The protective filter plate 4 and the protective box 6 seal and protect the double-layer condenser body 1, preventing dust in the air from directly contacting the heat dissipation fins on the double-layer condenser body 1 and preventing dust from sticking to the surface of the double-layer condenser body 1, which would affect the heat dissipation effect. Moreover, the air can be blown directly from the protective box 6 to the double-layer condenser body 1 without obstruction, ensuring the heat dissipation effect of the double-layer condenser body 1. The space corresponding to each group of second fans 17 is reduced by the partition 16, thereby ensuring the air flow speed in the air inlet chamber 10. The rotation of the second fan 17 allows outside air to enter the air inlet chamber 10. After entering the air inlet chamber 10, the air moves along the air channel formed by the first guide plate 11 and the second guide plate 12. The air flow direction changes from horizontal to flow along the second guide plate 12. When the air passes the second guide plate 12, it changes to horizontal flow again. Then the air flows along the air inlet chamber 10 and leaves from the air outlet. The air leaving from the air outlet passes through the first filter 9. The air blows the first filter 9 to clean it, thereby avoiding a large amount of impurities adhering to the first filter 9 and affecting the air intake, thus ensuring the heat dissipation effect of the double-layer condenser body 1. As air flows along the second guide plate 12, dust particles carried in the air also move with it. These dust particles then change direction with the airflow. Because the airflow narrows at the end of the second guide plate 12, the airflow speed increases, further increasing the speed of the dust particles inside the air. Due to inertia, a large number of dust particles move directly to the air outlet of the inlet chamber 10. Because the first fan 8 drives the airflow within the protective box 6, some air from the return chamber 13 enters the protective box 6, and some air from the inlet chamber 10 replenishes the return chamber 13. The second filter 15 filters the air entering the return chamber 13, ensuring that the air entering the protective box 6 is clean. Furthermore, due to the rapid airflow... The reason is that most of the dust particles carried in the air leave the air inlet chamber 10 directly, thereby reducing the number of dust particles that can come into contact with the second filter 15. This reduces the amount of dust at the source of air intake, further reducing the amount of dust particles adhering to the second filter 15, ensuring the cleanliness of the second filter 15, ensuring the air intake volume, and thus ensuring the cooling effect of the double-layer condenser body 1. At the same time, because the air flow at the end of the second guide plate 12 is faster and the air pressure is lower, the air flow speed in the area where the second filter 15 is located is lower and the air pressure is higher. As a result, the dust particles in the area where the second filter 15 is located and the dust particles cleaned off the second filter 15 will be drawn into the fast-flowing air and discharged under the action of air pressure, further reducing the probability of the second filter 15 becoming clogged and ensuring the air intake volume of the protective box 6.

[0028] like Figure 1 , Figure 3 , Figure 6 As shown, this invention provides a fast-cooling double-layer automotive air conditioner condenser. Multiple sets of brackets 18 are fixedly installed on the protective box 6. A frame-shaped movable frame 20 is slidably installed on the brackets 18. A first brush 21 for cleaning the first filter screen 9 is fixedly installed on the side of the movable frame 20 near the protective box 6. Multiple sets of through slots located between the first brushes 21 are opened on the movable frame 20. An electric telescopic rod 19 that drives the movable frame 20 to move back and forth is fixedly installed on the protective box 6.

[0029] Specifically, multiple sets of support plates 22 are fixedly installed on the movable frame 20. The support plates 22 are T-shaped and extend into the air inlet chamber 10. The position of the support plates 22 corresponds to the area separated by the partition plate 16. A second brush 23 that contacts the second filter screen 15 is fixedly installed on the support plate 22.

[0030] In practical application, the electric telescopic rod 19 drives the moving frame 20 to move back and forth. When the moving frame 20 moves back and forth, the first brush 21 cleans the first filter screen 9. At the same time, the moving frame 20 drives the second brush 23 through the support plate 22 to further clean the second filter screen 15. The dust particles cleaned off are blown away by the air, further ensuring the cleanliness of the first filter screen 9 and the second filter screen 15, ensuring the air intake of the protective box 6, and ensuring the cooling effect of the double-layer condenser body 1.
