Description

Technical Field

[0001] This article belongs to the technical field of drainage and ventilation systems for agricultural machinery evaporators, specifically relating to a leak-proof air conditioning housing. Background Technology

[0002] In agricultural machinery operation scenarios, the evaporator drainage and ventilation system is one of the core components for ensuring the temperature and humidity environment inside the cab. As the key carrier of the system, the rationality of the air conditioner housing directly affects the condensate treatment efficiency and system reliability.

[0003] The existing air conditioning casings used in current agricultural machinery, such as Figure 5 , 6 As shown, several potential water leakage hazards have been exposed during actual use. Specific problems are as follows: First, when outside air enters the casing through the air inlet and completes heat exchange through the evaporator core, a large amount of condensate forms and drips naturally. The air outlet is located in the middle of the condensate dripping path, and the airflow exiting the outlet atomizes or carries some of the liquid water, which is then discharged into the passenger compartment along with the airflow. This leads to water accumulation and abnormally high humidity in the passenger compartment, and the condensate adheres to the passenger compartment, which can easily cause short circuits and component corrosion over time. Second, the existing air conditioning casing uses a sloping transition structure between the rear and bottom surfaces. The tilt angle and surface roughness of the surface are insufficient to meet the requirements for smooth condensate drainage. When condensate drips onto the inclined area, due to the combined effect of surface tension and gravity, some condensate will be adsorbed and stuck on the inclined surface and cannot slide off quickly, forming a long-term stagnant water accumulation area. Thirdly, the bottom surface of the existing air conditioner casing is designed as a large-size planar structure. After condensate drips onto the bottom surface, it will spread irregularly on the plane and cannot quickly concentrate towards the drain pipe, resulting in a large amount of condensate remaining in different areas of the bottom surface. Under the bumpy and vibrating working conditions of agricultural machinery, the condensate remaining on the bottom surface will flow around with the shaking of the equipment and is more likely to come into contact with the air outlet area and be carried out by the airflow.

[0004] In summary, the structural defects of existing agricultural machinery air conditioner housings result in their condensate treatment capacity being unable to meet actual operational needs. Therefore, there is an urgent need for an improved housing structure that can efficiently guide, collect, and discharge condensate while preventing condensate from contacting the airflow at the air outlet. Utility Model Content

[0005] To address the aforementioned issues, this paper proposes a leak-proof air conditioner housing. The housing includes a front panel, a rear panel, a left side panel, a right side panel, a bottom panel, a water storage tank, a drain pipe, and a mounting support plate. The front panel has an air inlet, and the rear panel is symmetrically arranged with the front panel. Both the left and right side panels have air outlet pipes at their upper parts, which communicate with the interior of the housing. The bottom panel has a water storage tank at its lower part, with drain pipes at both ends, communicating with the interior of the water storage tank. The mounting support plate is positioned perpendicular to the front panel on the outer surface of the bottom panel. The water storage tank effectively collects condensate dripping from inside the housing, preventing it from spreading irregularly on the bottom panel surface. The condensate can quickly flow and converge towards the drain pipes at both ends, and is discharged through the drain pipes, effectively reducing the risk of leakage caused by condensate retention. In addition, the air outlet pipe is set at the top of the left and right side panels, which structurally prevents the airflow from the air outlet from directly contacting the condensate in the water storage tank, thereby reducing the possibility of condensate being carried out by the airflow and ensuring the dryness of the air conditioner's air outlet. This improves the performance and reliability of the agricultural machinery air conditioner. Through the synergistic effect of the above structures, the entire process of condensate generation, guidance, collection and discharge forms a closed loop, which significantly improves the water leakage prevention performance of the agricultural machinery air conditioner shell and effectively solves the problems of condensate retention, diffusion and being carried out by the airflow in traditional structures.

[0006] The evaporator core is placed inside the air conditioner casing. Through the spacing design between the evaporator core and the bottom plate of the casing, the evaporator core is positioned above the water storage tank, ensuring that the condensate can enter the water storage tank in an orderly and directional manner from the source, laying the foundation for the subsequent collection and discharge process.

[0007] The front and rear plates are vertically fixed to the front and rear ends of the base plate, respectively. The left and right plates are vertically fixed to the left and right sides of the base plate, respectively. The front, rear, base, left, and right plates together form the main body of the shell. Through the coordinated enclosure of the plates, a stable and well-sealed air conditioning shell frame is constructed, ensuring that an independent airflow and condensate circulation space is formed inside the shell. This multi-plate coordinated enclosure structure not only provides a solid installation foundation for internal components such as the evaporator core and air outlet pipe, but also ensures that the condensate flow path and airflow channel are independent and do not interfere with each other through a reasonable spatial layout. This structural design ensures the efficient operation of the leak-proof system and also enhances the overall rigidity and durability of the air conditioning shell to meet the needs of agricultural machinery under complex working conditions.

[0008] There are two air inlets, which are symmetrically arranged on the front panel. The symmetrical layout of the air inlets can effectively balance the airflow distribution into the housing, avoid airflow turbulence caused by airflow from one side, and ensure uniform air contact on the surface of the evaporator core, thereby improving heat exchange efficiency. It also reduces the problem of uneven condensate distribution that may be caused by local airflow being too fast or too slow.

[0009] The air outlet duct has a tubular structure, and its length is greater than the thickness of the left and right side panels. Through the extension design of the air outlet duct, it can pass through the left or right side panel and extend outward to the outside of the housing. This extension structure not only ensures the smoothness of the air outlet path, but also reduces the probability of external dust, moisture and other impurities entering the housing through the air outlet duct, thus affecting the normal operation of the air conditioning system.

[0010] The water storage tank has a rectangular structure and extends along the length of the base plate. The top opening of the water storage tank is flush with the base plate. This design allows condensate formed on the base plate to flow naturally into the water storage tank under gravity, preventing condensate from accumulating on the base plate surface. At the same time, the extension of the water storage tank along the length of the base plate increases the condensate collection area, ensuring that condensate dripping from the evaporator core and flowing from the base plate can be fully collected.

[0011] Beneficial effects:

[0012] By incorporating a water storage tank, condensate dripping from inside the casing can be collected and prevented from spreading irregularly on the bottom plate surface. It can then quickly flow and converge towards the drain pipes at both ends, effectively reducing the risk of leakage caused by condensate retention. Furthermore, the air outlet pipes are located on the upper part of the left and right side plates, structurally preventing the airflow from directly contacting the condensate in the water storage tank. This reduces the possibility of condensate being carried out by the airflow, ensuring the dryness of the air conditioner's output and improving the performance and reliability of the agricultural machinery air conditioner. Through the synergistic effect of these structures, the entire process of condensate generation, guidance, collection, and discharge forms a closed loop, significantly improving the leak-proof performance of the agricultural machinery air conditioner casing and effectively solving the problems of condensate retention, diffusion, and being carried out by the airflow in traditional structures.

[0013] By designing the distance between the evaporator core and the bottom plate of the shell, the evaporator core is positioned above the water storage tank, ensuring that the condensate can enter the water storage tank in an orderly and directional manner from the source, laying the foundation for the subsequent collection and discharge process.

[0014] By using the coordinated enclosure of various plates, a stable and well-sealed air conditioning housing frame is constructed, ensuring that an independent airflow and condensate circulation space is formed inside the housing. This multi-plate coordinated enclosure structure not only provides a solid installation foundation for internal components such as the evaporator core and air outlet pipe, but also ensures that the condensate flow path and airflow channel are independent and do not interfere with each other through a reasonable spatial layout. This structural design guarantees the efficient operation of the leak-proof system and also enhances the overall rigidity and durability of the air conditioning housing to meet the needs of agricultural machinery under complex working conditions.

[0015] The symmetrical layout design of the air inlet can effectively balance the airflow distribution entering the shell, avoid airflow turbulence caused by unilateral air intake, thus ensuring uniform air contact on the surface of the evaporator core, improving heat exchange efficiency, and also reducing the problem of uneven condensate distribution that may be caused by local airflow being too fast or too slow.

[0016] By extending the air outlet duct through the left or right side panel and outward to the outside of the housing, this extended structure not only ensures a smooth air outlet path but also reduces the probability of external dust, moisture, and other impurities entering the housing through the air outlet duct, thus affecting the normal operation of the air conditioning system.

[0017] The design of the top opening of the water storage tank being flush with the bottom plate allows the condensate formed on the bottom plate to flow naturally into the water storage tank under the action of gravity, preventing the condensate from accumulating on the surface of the bottom plate. At the same time, the water storage tank extends along the length of the bottom plate, increasing the collection area of ​​the condensate and ensuring that the condensate dripping from the evaporator core and flowing from the bottom plate can be fully collected.

[0025] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0026] Front panel 1, air inlet 101, left side panel 2, bottom panel 3, rear panel 4, right side panel 5, water tank 6, drain pipe 601, air outlet pipe 7, mounting support plate 8, sloping panel 9.

[0027] like Figure 1 , 2 As shown in Figures 3 and 4;

[0028] A leak-proof air conditioner housing includes a front panel 1, a rear panel 4, a left side panel 2, a right side panel 5, a bottom plate 3, a water storage tank 6, a drain pipe 601, and a mounting support plate 8. The front panel 1 has an air inlet 101. The rear panel 4 is symmetrically arranged with the front panel 1. Both the left side panel 2 and the right side panel 5 have air outlet pipes 7 on their upper parts, which communicate with the interior of the housing. The bottom plate 3 has a water storage tank 6 at its lower part, with drain pipes 601 at both ends of the water storage tank 6, which communicate with the interior of the water storage tank 6. The mounting support plate 8 is located on the outer surface of the bottom plate 3 and is perpendicular to the front panel 1. An evaporator core is placed inside. The front plate 1 and rear plate 4 are respectively vertically fixed to the front and rear ends of the base plate 3. The left side plate 2 and right side plate 5 are respectively vertically fixed to the left and right sides of the base plate 3. The front plate 1, rear plate 4, base plate 3, left side plate 2 and right side plate 5 together form the main body of the shell. There are two air inlets 101, which are symmetrically arranged on the front plate 1. The air outlet 7 is a tubular structure, and the length of the air outlet 7 is greater than the thickness of the left side plate 2 and right side plate 5. The water storage tank 6 is a cuboid structure, which extends along the length of the base plate 3. The top opening of the water storage tank 6 is flush with the base plate 3.

[0029] Implementation example;

[0030] External air enters through the air inlet 101, and after passing through the evaporator core 10, it produces condensate. The condensate generated during operation flows along the bottom plate 3 into the water storage tank 6, and then is discharged outside the casing through the drain pipes 601 at both ends of the water storage tank 6, thus preventing condensate leakage. At the same time, since the air outlet pipe 7 is located on the upper part of the left side plate 2 and the right side plate 5 of the casing, the airflow will not come into contact with the dripping condensate, thus preventing the condensate from being carried out.
