Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning, and in particular to a high-efficiency drainage structure for automotive air conditioning condensers. Background Technology

[0002] In automotive air conditioning systems, the condenser is typically located at the front of the vehicle, adjacent to the radiator. Its operation involves heat exchange with outside air, converting the high-temperature, high-pressure gaseous refrigerant into a low-temperature, high-pressure liquid refrigerant. As one of the four essential components of an air conditioning system, the condenser's heat exchange performance directly impacts the overall system performance.

[0003] During the condensation process, outside air flows over the condenser fins and pipe surfaces, cooling them. When the ambient air humidity is high, water vapor in the air easily condenses into water droplets on the condenser surface, which is below the dew point temperature, forming condensate.

[0004] If these condensation droplets adhere to the surface of pipes or heat sink fins, on the one hand, they can easily form an additional thermal resistance layer, which may hinder the heat exchange between the condenser and the outside air, thus reducing condensation efficiency and affecting the operating efficiency of the air conditioning system; on the other hand, during vehicle operation, especially at high speeds, the airflow may blow off the attached water droplets, which may wet other components in the engine compartment, and over time may lead to corrosion of metal parts or short circuits in electrical components. Utility Model Content

[0005] This invention provides a high-efficiency drainage structure for automotive air conditioning condensers, which can solve the problem in the prior art where condensate droplets adhere to the surface of pipes or heat sink fins, easily forming an additional thermal resistance layer, and splashing easily wets other components in the engine compartment, affecting the reliability of the automotive air conditioning system.

[0006] A high-efficiency drainage structure for an automotive air conditioning condenser includes a frame and multiple fins disposed on the frame. The surface of the fins is provided with multiple drainage components arranged in sequence. Each drainage component includes a main water collection channel disposed on the surface of the fins and multiple guide channels disposed on the surface of the fins. The tail ends of the guide channels are all connected to the main water collection channel. Under the action of external wind, the condensate on the fins can flow along the guide channels into the main water collection channel and be discharged. A flow guiding component is provided on the fin and on the side near the main water collection channel. The flow guiding component is used to guide the condensate on the fin surface into the flow guiding branch channel.

[0007] Preferably, the flow guiding assembly includes a flow blocking portion disposed on the fin and a flow guiding groove disposed on the surface of the fin, wherein the flow guiding groove communicates with the flow guiding branch groove.

[0008] Preferably, the flow guide channel is arranged parallel to the direction of external wind blowing, and the main water collection channel is arranged perpendicular to the flow guide channel.

[0009] Preferably, the flow-blocking part is located on the front side of the main water collection channel, and the flow-blocking part is located between the diversion channel and the main water collection channel.

[0010] Preferably, the rear side wall of the main water collection channel is provided with a windbreak, which is inclined towards the front side of the main water collection channel.

[0011] Preferably, a closed section is provided between the front end of the diversion branch channel and the adjacent main water collection channel.

[0012] Preferably, the deflector is provided with a guide section, and the windward side of the guide section is provided with a guide surface.

[0013] Preferably, a drainage trough is provided on the bottom side of the frame and below the main water collection trough, with one end of the drainage trough extending to the outer surface of the frame.

[0014] Preferably, a guide plate is fixed at the bottom of the fin and below the main water collection channel, and the guide plate extends into the drainage channel.

[0015] Preferably, the bottom wall of the guide channel is inclined towards the tail end, and the bottom wall of the drainage channel is inclined towards the outside of the frame.

[0016] This utility model provides a high-efficiency drainage structure for automotive air conditioning condensers, which has the following beneficial effects: 1. Through the cooperation of the guide channel and the main water collection channel, the condensate is collected from the surface of the fins and pipes and discharged in a directional manner by the external wind force, which reduces the residence time and coverage area of ​​water droplets on the heat exchange surface, thereby reducing the additional thermal resistance formed by the water film, ensuring the heat exchange efficiency of the condenser, and helping to maintain the operating energy efficiency of the air conditioning system.

[0017] 2. The baffle section blocks the splashing water and guides it to diffuse upwards and downwards, while the diversion channel further guides the condensate into the guide branch channel for collection, and finally discharges it into the main water collection channel. The synergy between the guide branch channel, the baffle section, and the diversion channel suppresses the splashing of condensate droplets, thereby reducing the possibility of condensate wetting other components in the engine compartment and protecting them.

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 5 As shown in the figure, an embodiment of this utility model provides a high-efficiency drainage structure for an automotive air conditioning condenser, including a frame 1 and multiple fins 2 disposed on the frame 1. Multiple drainage components 3 are arranged sequentially on the surface of the fins 2. Each drainage component 3 includes a main water collection channel 31 disposed on the surface of the fins 2 and multiple guide channels 32 disposed on the surface of the fins 2. The tail ends of the guide channels 32 are all connected to the main water collection channel 31. Under the action of external wind, condensate on the fins 2 can flow along the guide channels 32 into the main water collection channel 31 and be discharged. A guide component 4 is disposed on the side of the fins 2 near the main water collection channel 31. The guide component 4 is used to guide the condensate on the surface of the fins 2 into the guide channel 32. The guide component 4 includes a baffle portion 41 disposed on the fins 2 and a guide channel 42 disposed on the surface of the fins 2, the guide channel 42 being connected to the guide channels 32.

[0022] During the operation of the condenser, the guide channel 32 forms a water collection network on the surface of the fins 2. When the external fan starts and blows air onto the fins 2 of the condenser, on the one hand, the condensate inside the guide channel 32 is more smoothly collected into the main water collection channel 31 by the airflow; on the other hand, the remaining condensate on the surface of the fins 2 is dispersed and flows under the force of the airflow, with some flowing into the guide channel 32 and the other flowing to the front of the main water collection channel 31. At this time, the baffle 41 acts as a barrier, causing the condensate to diffuse upwards and downwards, while the guide channel 42 guides the condensate into the guide channel 32 for collection, and finally into the main water collection channel 31 for centralized discharge.

[0023] Through the cooperation of the guide channel 32 and the main water collection channel 31, condensate can be collected from the fins 2 and the pipe surface and discharged in a directional manner, reducing the residence time and coverage area of ​​water droplets on the heat exchange surface. This reduces the additional thermal resistance caused by the water film, ensuring the heat exchange efficiency of the condenser and helping to maintain the operating efficiency of the air conditioning system. Furthermore, under the action of external airflow, the baffle 41 can block the scattered water flow and guide it to diffuse to the upper and lower sides, while the diversion channel 42 further guides the condensate to the guide channel 32 for collection and finally discharges it into the main water collection channel 31. The synergy of the guide channel 32, the baffle 41, and the diversion channel 42 suppresses the splashing of condensate droplets, thereby reducing the phenomenon of condensate splashing onto other components in the engine compartment and protecting other components in the engine compartment.

[0024] In some specific implementation plans, such as Figure 4 and Figure 5 As shown, the guide channel 32 is arranged parallel to the direction of external wind blowing. The guide channel 32, which is parallel to the direction of wind flow, facilitates the flow of internal water by wind. The main water collection channel 31 is arranged perpendicular to the guide channel 32. The baffle 41 is located on the front side of the main water collection channel 31 and is located between the diversion channel 42 and the main water collection channel 31. This allows the remaining condensate on the surface of the fin 2 to be blocked by the baffle 41 and then flow into the guide channel 32 through the diversion channel 42.

[0025] In some specific implementation plans, such as Figure 4 and Figure 5 As shown, a windbreak 5 is provided on the rear side wall of the main water collection channel 31. The windbreak 5 is inclined towards the front of the main water collection channel 31 and is correspondingly provided at the tail end of the guide branch channel 32. A sealing part 7 is provided between the front end of the guide branch channel 32 and the adjacent main water collection channel 31. A guide part 6 is provided on the flow-blocking part 41, and a guide curved surface is provided on the windward side of the guide part 6.

[0026] When the external fan blows air onto the condenser, the airflow flows on the surface of the fins 2, while some of the airflow also blows water into the guide channel 32. When the airflow inside the guide channel 32 flows into the main water collection channel 31, the windbreak 5 blocks the flow of water and air into the main water collection channel 31 to prevent the water blown by the wind from overflowing outside the main water collection channel 31. Furthermore, the sealing section 7 seals the front ends of the main water collection channel 31 and the guide channel 32, preventing water blown into the right guide channel 32 from flowing back into the left guide channel 32, ensuring normal water collection and discharge. In addition, the front side of the main water collection channel 31 (the side that first comes into contact with the wind) is blocked by the air guide section 6. The slightly protruding structure of the air guide section 6 guides the wind across the main water collection channel 31, preventing the wind flow from interfering with the normal collection and flow of water inside the main water collection channel 31.

[0027] In some specific implementation plans, such as Figure 1 , Figure 2 and Figure 5 As shown, a drainage trough 9 is provided on the bottom side of the frame 1 and below the main water collection trough 31. One end of the drainage trough 9 extends to the outer surface of the frame 1. A guide plate 8 is fixed at the bottom of the fin 2 and below the main water collection trough 31. The guide plate 8 extends into the drainage trough 9.

[0028] The water collected inside the main water collection trough 31 flows into the drainage trough 9 and is then discharged outside the vehicle. A guide plate 8 is installed at the connection between the main water collection trough 31 and the drainage trough 9 to prevent the wind from affecting the free fall of the water inside the main water collection trough 31 into the drainage trough 9, thus ensuring the normal discharge of the water.

[0029] The bottom wall of the guide channel 32 is inclined towards the rear end, and the front end of the guide channel 32 is inclined towards the rear end, so as to help the water inside the guide channel 32 flow to the main water collection channel 31. The bottom wall of the drainage channel 9 is inclined towards the outside of the frame 1, so as to help the water inside the drainage channel 9 drain under the vehicle chassis.

[0030] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: During the operation of the condenser, the guide channel 32 forms a water collection network on the surface of the fins 2. When the external fan starts and blows air onto the fins 2 of the condenser, on the one hand, the condensate inside the guide channel 32 is more smoothly collected into the main water collection channel 31 by the airflow; on the other hand, the remaining condensate on the surface of the fins 2 is dispersed and flows under the force of the airflow, with some flowing into the guide channel 32 and the other flowing to the front of the main water collection channel 31. At this time, the baffle 41 acts as a barrier, causing the condensate to diffuse upwards and downwards, while the guide channel 42 guides the condensate into the guide channel 32 for collection, and finally into the main water collection channel 31 for centralized discharge.

[0031] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
