Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to a parking air conditioner. Background Technology

[0002] A parking air conditioner is an air conditioner used when parking and waiting or resting. It is usually installed on trucks and vans, and drivers can use it during long-distance driving. As people's demands for driving comfort continue to increase, parking air conditioners have become one of the essential pieces of equipment in the car cabin.

[0003] Parking air conditioners typically consist of a chassis and an insulation cover mounted on the chassis. The insulation cover connects to the chassis to form an internal heat exchange duct. The ambient air inside the vehicle exchanges heat with an internal heat exchanger within this duct. To accommodate the installation space limitations of low-roof cabs in light trucks and mini-trucks, the overall height and volume of the parking air conditioner must be strictly limited to a small range.

[0004] However, existing insulation covers are mostly made in one piece. The thickness of the foam, combined with the height of the chassis and internal heat exchanger, results in a generally high overall height, making it difficult to meet the installation requirements of low-roof vehicles. In addition, due to the compact layout of the internal heat exchange air duct, the air intake of the internal heat exchange fan is too close to the water collection tray. When the internal heat exchange fan is running, negative pressure is formed near both ends of the water collection tray, which easily rolls up the condensate at both ends of the water collection tray and blows it out from the internal air outlet with the airflow, causing water blowing problems and seriously affecting the user experience. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore,

[0006] This utility model provides a parking air conditioner, which includes:

[0007] The chassis is provided with a through internal air inlet and an internal air outlet;

[0008] An insulation cover is connected above the chassis and defines an internal heat exchange air duct with the chassis. The internal heat exchange air duct is connected to the internal air inlet and the internal air outlet.

[0009] An internal heat exchanger is provided in the internal heat exchange air duct, and the internal heat exchanger is located between the internal air inlet and the internal air outlet.

[0010] A water collection tray is provided inside the internal heat exchange air duct, and the water collection tray is located below the internal heat exchanger;

[0011] An internal heat exchanger is installed inside the internal heat exchange duct, and the air outlet of the internal heat exchanger is connected to the internal air outlet.

[0012] The heat insulation cover includes:

[0013] The first cover is disposed on the chassis and located on one side of the top surface of the internal heat exchanger;

[0014] The second cover is mounted on the chassis. The first cover and the second cover are detachably connected and surround the inner heat exchanger. The height of the second cover and the first cover is not higher than the top surface height of the inner heat exchanger.

[0015] The above technical solution has the following advantages or beneficial effects: by splitting the heat insulation cover into a two-section design of a first cover and a second cover, the first cover and the second cover are each located on one side of the top surface of the inner heat exchanger, and their height is not higher than the top surface of the inner heat exchanger. There is no need for the redundant transition layer of the integrated heat insulation cover. This not only reduces the amount of material used in the heat insulation cover and lowers the cost, but also effectively reduces the height of the heat insulation cover, thereby reducing the overall height of the parking air conditioner.

[0016] According to an embodiment of this disclosure, the inner air inlet and the inner air outlet are spaced apart along the thickness direction of the inner heat exchanger, and the first cover and the second cover are arranged along the thickness direction of the inner heat exchanger.

[0017] The above technical solution has the following advantages or beneficial effects: the above arrangement allows the internal heat exchanger to have a separate cover above it, and the corresponding first cover or second cover can be disassembled separately to maintain the internal heat exchanger, thereby improving the convenience of maintenance.

[0018] According to an embodiment of this disclosure, drainage holes are provided at both ends of the water receiving tray along its length, and an anti-negative pressure plate is provided above the drainage holes. The anti-negative pressure plate abuts against the end of the water receiving tray and blocks the drainage holes.

[0019] The above technical solution has the following advantages or beneficial effects: by setting anti-negative pressure plates at both ends of the water receiving pan, the formation of negative pressure at both ends of the water receiving pan is broken, effectively preventing the problem of water blowing from the parking air conditioner. At the same time, the anti-negative pressure plates block the drain holes, which can prevent airflow from interfering with drainage and reduce the risk of water accumulation.

[0020] According to an embodiment of this disclosure, two internal heat exchange fans are arranged along the length of the water receiving tray, the distance between the end of the water receiving tray and the air intake of the adjacent internal heat exchange fan is L1, and the length dimension L2 of the anti-negative pressure plate is not less than L1.

[0021] The above technical solution has the following advantages or beneficial effects: by setting the length L2 of the anti-negative pressure plate to be no less than L1, the anti-negative pressure plate can accurately cover the negative pressure affected area of ​​the internal heat exchange fan at both ends of the water receiving pan, thereby enhancing the anti-blowing effect.

[0022] According to an embodiment of this disclosure, the water receiving tray includes two waterproof ribs extending along the length direction of the internal heat exchanger. The two waterproof ribs are arranged at intervals along the thickness direction of the internal heat exchanger. The waterproof rib closer to the internal heat exchange fan is defined as the first waterproof rib. The drain hole is located close to the first waterproof rib. The anti-negative pressure plate is located between the first waterproof rib and the internal heat exchanger.

[0023] The above technical solution has the following advantages or beneficial effects: the anti-negative pressure plate is located between the first waterproof rib and the internal heat exchanger, so that the anti-negative pressure plate can better cover the end of the internal heat exchanger, the water receiving pan, and the part of the water receiving pan between the first water baffle rib and the part close to the internal heat exchange fan, thereby playing a better role in preventing negative pressure, avoiding water blowing, and improving the user experience.

[0024] According to an embodiment of this disclosure, the first waterproof rib is provided with a mounting part on the side opposite to the internal heat exchanger, the anti-negative pressure plate is provided with a through hole, and the anti-negative pressure plate is fixedly connected to the mounting part by fasteners passing through the through hole.

[0025] The above technical solution has the following advantages or beneficial effects: the anti-negative pressure plate is fixedly connected by fasteners, which can prevent the anti-negative pressure plate from vibrating and falling off, and adapt to the bumpy environment of the vehicle.

[0026] According to an embodiment of this disclosure, the chassis has two annular enclosures, one of which is located inside the outline of the other, and the bottom end of the heat insulation cover is located at the top of the two annular enclosures.

[0027] The above technical solution has the following advantages or beneficial effects: By installing double-ringed enclosures on the chassis, the insulation cover fits over the top of the ringed enclosures, forming a double-sealed structure and reducing heat loss. Specifically, the double-ringed enclosures improve insulation performance by 15% compared to single-ringed enclosures.

[0028] According to embodiments of this disclosure, one of the two annular enclosures closer to the internal heat exchanger is defined as the first annular enclosure and the other as the second annular enclosure, wherein the height of the first annular enclosure is higher than the height of the second annular enclosure.

[0029] The above technical solution has the following advantages or beneficial effects: the first annular enclosure is higher than the second annular enclosure, which can form a stepped seal at the connection between it and the insulation cover, effectively avoiding air leakage and improving the insulation effect. At the same time, the height difference design can also reduce the amount of materials used and reduce costs.

[0030] According to an embodiment of this disclosure, the parking air conditioner further includes a pressure strip. The bottom ends of the first cover and the second cover are provided with flanges that meet. A first through hole is provided on the flange. The pressure strip spans the two flanges and is provided with a second through hole. Fasteners pass through the second through hole and the first through hole and are fixed to the chassis to press the first cover and the second cover onto the chassis.

[0031] The above technical solution has the following advantages or beneficial effects: the first cover and the second cover are joined by a flange, and the pressure strip is connected across the flange and fixed with fasteners to ensure the integrity of the segmented heat insulation cover. By setting the pressure strip, it is not only convenient to disassemble the heat insulation cover, but also conducive to improving the heat insulation performance of the heat insulation cover.

[0032] According to embodiments of this disclosure, a parking air conditioner is also provided, comprising:

[0033] The chassis is provided with a through internal air inlet and an internal air outlet;

[0034] An insulation cover is connected above the chassis and defines an internal heat exchange air duct with the chassis. The internal heat exchange air duct is connected to the internal air inlet and the internal air outlet.

[0035] An internal heat exchanger is provided in the internal heat exchange air duct, and the internal heat exchanger is located between the internal air inlet and the internal air outlet.

[0036] An internal heat exchanger is installed in the internal heat exchange duct, and the air outlet of the internal heat exchanger is connected to the internal air outlet.

[0037] The heat insulation cover includes:

[0038] First cover;

[0039] The second cover, together with the first cover, defines a through section. The through section is connected to the internal heat exchange duct, and the internal heat exchanger passes through the through section.

[0040] The height of the heat insulation cover is not higher than the height of the top surface of the internal heat exchanger.

[0041] The above technical solution has the following advantages or beneficial effects: by setting an insulation cover on the chassis formed by the connection of the first cover and the second cover, the two together define the through part, so that the vertically arranged internal heat exchanger can be directly inserted into it and placed in the internal heat exchange air duct. The insulation cover does not cover the internal heat exchanger, which can not only reduce the height of the insulation cover, thereby reducing the overall height of the parking air conditioner, but also significantly reduce the amount of material used in the insulation cover and reduce the cost.

[0064] This utility model proposes a parking air conditioner 100, which is a top-mounted integrated air conditioner installed on the top of the vehicle's cab to create a comfortable environment for the cab.

[0065] The parking air conditioner 100 provided in this utility model embodiment can have various implementation forms, as detailed below. Figures 1-16 The parking air conditioner 100 is described.

[0066] In some embodiments of this application, reference is made to Figure 1 The parking air conditioner 100 may include a chassis 1. The chassis 1 is connected above the roof panel.

[0067] Continue to refer to Figure 1 The parking air conditioner 100 may include a housing 2, which is connected to the underside of the chassis 1. The chassis 1 and the housing 2 are connected to define a receiving cavity. The receiving cavity is used to house and fix various components in the parking air conditioner 100, which can prevent external objects from colliding with the various components in the receiving cavity, thereby improving the reliability of the parking air conditioner 100 during transportation or installation.

[0068] refer to Figure 7 The chassis 1 is provided with a through internal air inlet 11 and an internal air outlet 12, and the cavity is defined by an internal heat exchange air duct.

[0069] The internal heat exchange duct is connected to the internal air inlet 11. The internal air inlet 11 serves as the inlet for external air to flow into the internal heat exchange duct, allowing air from inside the vehicle to enter the internal heat exchange duct through the internal air inlet 11.

[0070] The internal heat exchange duct is connected to the internal air outlet 12. The internal air outlet 12 serves as the outlet for the airflow in the internal heat exchange duct, allowing the airflow in the internal heat exchange duct to flow out to the interior environment of the vehicle through the internal air outlet 12.

[0071] In some embodiments of this application, reference is made to Figure 2 The parking air conditioner 100 may include an inner shell 3, which is connected to the underside of the chassis 1. The inner shell 3 extends into the vehicle interior through a sunroof on the roof panel.

[0072] Continue to refer to Figure 2 An internal air inlet 31 and an internal air outlet 32 ​​are formed on the inner shell 3, and an internal air inlet duct 36 and an internal air outlet duct 37 are defined inside the inner shell 3.

[0073] The internal air intake duct 36 connects the internal air intake port 31 and the internal air intake passage 11, allowing air inside the vehicle to enter the internal heat exchange duct sequentially through the internal air intake port 31, the internal air intake duct 36, and the internal air intake passage 11. The internal air outlet duct 37 connects the internal air outlet 32 ​​and the internal air outlet passage 12, allowing airflow within the internal heat exchange duct to enter the vehicle interior environment sequentially through the internal air outlet passage 12, the internal air outlet duct 37, and the internal air outlet 32.

[0074] refer to Figure 4 The inner shell 3 may include an inner bottom plate 33, and the inner air outlet 32 ​​may be provided on the inner bottom plate 33.

[0075] In some embodiments of this application, an air guide structure may be provided at the internal air outlet 32 ​​to adjust the airflow direction.

[0076] The inner shell 3 may include an inner side plate 34, and an inner bottom plate 33 is connected to the chassis 1 through the inner side plate 34. The inner air inlet 31 may be provided on the inner bottom plate 33 and / or the inner side plate 34.

[0077] In some embodiments of this application, reference is made to Figure 4 The parking air conditioner 100 may include an internal heat exchanger 5, which is vertically disposed in an internal heat exchange duct and is used to exchange heat with the airflow in the internal heat exchange duct.

[0078] refer to Figure 7 The internal heat exchanger 5 is located between the internal air inlet 11 and the internal air outlet 12.

[0079] The parking air conditioner 100 may include an internal heat exchange fan 6, which is located in an internal heat exchange duct. When the internal heat exchange fan 6 rotates, it drives air to enter the internal heat exchange duct through the internal air inlet 31 and exchange heat with the internal heat exchanger 5. Then, it drives the airflow in the internal heat exchange duct to be blown out from the internal air outlet 32.

[0080] In some embodiments of this application, reference is made to Figure 2 An external air intake 13 is also formed on the chassis 1, and the external air intake 13 is connected to the accommodating cavity. The external air intake 13 allows outside air from the vehicle to enter the accommodating cavity.

[0081] In some embodiments of this application, reference is made to Figure 1 The outer casing 2 is provided with an exhaust vent 21, which is connected to the accommodating cavity. The exhaust vent 21 allows air in the accommodating cavity to flow out to the external environment of the vehicle.

[0082] The parking air conditioner 100 may include an external heat exchanger 74, which is disposed within a housing cavity and used for heat exchange with the air in the housing cavity. (Reference) Figure 5 The external heat exchanger 74 is located above the chassis 1 and is positioned near the external air inlet 13.

[0083] The parking air conditioner 100 may include an external fan cover 71, which is positioned above the external heat exchanger. (Reference) Figure 1 and Figure 5 An opening is formed on the top of the external fan cover 71, and the opening is connected to the external air outlet 21.

[0084] The parking air conditioner 100 may include an external fan 73, which is housed in an external fan cover 71 and has corresponding openings. When the external fan 73 rotates, it drives outside air from the vehicle to enter the accommodating cavity through the external air inlet 13, exchange heat with the external heat exchanger, and then exit through the openings of the external fan cover 71, and finally be blown out through the external air outlet 21.

[0085] The parking air conditioner 100 may include a compressor 72, which is disposed within a housing cavity. The compressor 72 may be located on the left or right side of the external fan shroud 71.

[0086] The parking air conditioner 100 may include a throttling device disposed within a receiving cavity for throttling.

[0087] The internal heat exchanger 5 and the external heat exchanger are used as condensers or evaporators. When the internal heat exchanger 5 is used as a condenser, the air conditioner is used as a heater in heating mode; when the internal heat exchanger 5 is used as an evaporator, the parking air conditioner 100 is used as a cooler in cooling mode.

[0088] The refrigeration and heating cycles include compression, condensation, expansion, and evaporation processes. By absorbing and releasing heat through the refrigerant, they provide cooling or heating to the vehicle interior, thereby regulating the temperature inside the vehicle.

[0089] The compressor 72 compresses the refrigerant gas into a high temperature and high pressure state and discharges the compressed refrigerant gas, which flows into the condenser.

[0090] The condenser condenses the compressed, high-temperature, high-pressure gaseous refrigerant into a liquid refrigerant, and the heat is released to the surrounding environment through the condensation process.

[0091] The liquid refrigerant flowing out of the condenser enters the throttling device, which expands the high-temperature, high-pressure liquid refrigerant after condensation in the condenser into a low-pressure liquid refrigerant.

[0092] The low-pressure liquid refrigerant flowing out of the throttling device enters the evaporator. As the liquid refrigerant flows through the evaporator, it absorbs heat and evaporates into a low-temperature, low-pressure refrigerant gas. The low-temperature, low-pressure refrigerant gas returns to the compressor 72.

[0093] The evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout this entire cycle, the parking air conditioner 100 regulates the temperature inside the vehicle.

[0094] In some embodiments of this application, the parking air conditioner 100 may include a heat insulation cover 4, which is connected to the chassis 1, and the heat insulation cover 4 and the chassis 1 define an internal heat exchange duct located between them.

[0095] By setting up an insulation cover 4 and enclosing it with the chassis 1 to form a relatively closed internal heat exchange air duct, an independent and controllable internal heat exchange circulation path is formed, which has a good insulation effect and is conducive to improving heat exchange efficiency and cooling performance.

[0096] In related technologies, the heat insulation cover 4 is an integrated heat insulation cover 4. The integrated heat insulation cover 4 is covered on the chassis 1 and placed on the outside of the inner heat exchanger 5, which results in the high height of the integrated heat insulation cover 4, which in turn results in the high height of the whole machine, which is not conducive to miniaturization.

[0097] In order to reduce the height and volume of the parking air conditioner 100, in some embodiments of this application, the insulation cover 4 adopts a split design to avoid covering the top of the inner heat exchanger 5 as a whole, which can reduce the height of the insulation cover 4 and thus reduce the overall height of the unit. Compared with the insulation box of integrated insulation foam, it can be reduced by at least 10mm, which meets the needs of light trucks and other scenarios where space is extremely sensitive.

[0098] Specifically, reference Figures 8-11 The heat insulation cover 4 may include a first cover body 41, which is mounted on the chassis 1 and located on one side of the top surface of the inner heat exchanger 5.

[0099] The heat insulation cover 4 may include a second cover 42, and the first cover 41 and the second cover 42 are detachably connected and surround the inner heat exchanger 5.

[0100] The first cover 41 and the second cover 42 are spliced ​​around the heat exchanger to ensure the integrity of the insulation, while the detachable design provides an access point for subsequent maintenance.

[0101] The second cover 42 is located on the chassis 1, on the other side of the top surface of the inner heat exchanger 5. The height of the first cover 41 and the second cover 42 is not higher than the height of the top surface of the inner heat exchanger 5.

[0102] By dividing the heat insulation cover 4 into sections, with the first cover 41 and the second cover 42 respectively located on both sides of the internal heat exchanger 5, unnecessary coverage area is reduced, and material usage and height are decreased.

[0103] Specifically, in this embodiment, by splitting the insulation cover 4 into a two-section design of a first cover 41 and a second cover 42, the first cover 41 and the second cover 42 are each located on one side of the top surface of the inner heat exchanger 5, and their height is not higher than the top surface of the inner heat exchanger 5. The redundant transition layer of the integrated insulation cover 4 is not required, which can not only reduce the amount of material used in the insulation cover 4 and reduce the cost, but also effectively reduce the height of the insulation cover 4, thereby reducing the overall height of the parking air conditioner 100.

[0104] In some embodiments of this application, the inner air inlet 11 and the inner air outlet 12 are spaced apart along the thickness direction of the inner heat exchanger 5, and the first cover 41 and the second cover 42 are arranged along the thickness direction of the inner heat exchanger 5.

[0105] Specifically, the first cover 41 and the second cover 42 are respectively located on both sides of the thickness direction of the inner heat exchanger 5. That is to say, one of the first cover 41 and the second cover 42 is located above the inner air inlet 11, and the other is located above the inner heat exchange fan 6.

[0106] refer to Figure 10 In this embodiment, the second cover 42 is located above the internal heat exchanger 6. When the internal heat exchanger 6 needs maintenance, only the second cover 42 needs to be removed, which facilitates maintenance of the internal heat exchanger 6 and improves maintenance convenience.

[0107] In some embodiments of this application, reference is made to Figure 15 The parking air conditioner 100 may include a drip tray 8, which is mounted on the chassis 1. The drip tray 8 is located in the internal heat exchange duct and below the internal heat exchanger 5, and is used to collect condensate to improve safety performance.

[0108] refer to Figure 13 , Figure 15 The water receiving tray 8 extends along the left and right direction of the base plate 1. The width of the water receiving tray 8 is greater than the width of the bottom of the internal heat exchanger 5, so that the water receiving tray 8 can better receive the condensate on the internal heat exchanger 5.

[0109] In some embodiments of this application, drain holes 81 are provided at both ends of the water receiving tray 8 along its length. The water receiving tray 8 collects condensate from the internal heat exchanger 5 and discharges it through the drain holes 81. By providing drain holes 81 at both ends of the water receiving tray 8, rapid drainage of the water receiving tray 8 can be achieved, effectively preventing water accumulation and the growth of bacteria / odors.

[0110] In some embodiments of this application, two internal heat exchange fans 6 are arranged along the length of the water receiving tray 8. The internal heat exchange fans 6 can be centrifugal fans.

[0111] The dual centrifugal fan layout increases air volume and static pressure, making it suitable for the narrow space of a light truck cab, while also balancing the drainage needs at both ends of the water tray 8.

[0112] In related technologies, due to the compact internal structure of the insulation cover 4, the centrifugal fan is close to the water receiving tray 8 below the inner heat exchanger 5, which often results in water blowing from the inner air outlet 32, leading to a poor user experience.

[0113] To resolve the aforementioned technical issues, please refer to [the relevant source]. Figure 13 In some embodiments of this application, an anti-negative pressure plate 9 is provided above the drain hole 81. The anti-negative pressure plate 9 abuts against the end of the water receiving tray 8, and the anti-negative pressure plate 9 blocks the drain hole 81.

[0114] In this embodiment, by setting anti-negative pressure plates 9 at both ends of the water receiving tray 8, the formation of negative pressure at both ends of the water receiving tray 8 is broken, effectively solving the problem of water blowing from the internal air outlet 32 ​​due to the close proximity of the internal heat exchange fan 6 to the water receiving tray 8, thus improving the user experience. At the same time, the anti-negative pressure plates 9 block the drain hole 81, which can prevent airflow from interfering with drainage and reduce the risk of water accumulation.

[0115] refer to Figure 14 The distance between the end of the water receiving tray 8 and the air intake 61 of the nearby internal heat exchanger 6 is L1, and the length of the anti-negative pressure plate 9 is L2, wherein L2 is not less than L1.

[0116] In this embodiment, by setting the length L2 of the anti-negative pressure plate 9 to be no less than L1, the anti-negative pressure plate 9 can accurately cover the negative pressure affected area of ​​the internal heat exchange fan 6 at both ends of the water receiving pan 8, thereby strengthening the anti-blowing effect and effectively eliminating the blow-out problem.

[0117] In some embodiments of this application, the water receiving tray 8 may include two waterproof ribs extending along the length of the inner heat exchanger 5. The two waterproof ribs are spaced apart along the thickness of the inner heat exchanger 5.

[0118] The waterproof rib closest to the internal heat exchanger 6 is defined as the first waterproof rib 82, and the other waterproof rib is defined as the second waterproof rib 83. The first waterproof rib 82 can form a water-retaining wall to prevent water from seeping into the fan area. The second waterproof rib 83 can guide condensate water to flow in a specific direction to the drain hole 81.

[0119] refer to Figure 12 The drain hole 81 is located near the first waterproof rib 82, and the anti-negative pressure plate 9 is located between the first waterproof rib 82 and the internal heat exchanger 5.

[0120] In this embodiment, the anti-negative pressure plate 9 is located between the first waterproof rib 82 and the internal heat exchanger 5, utilizing the existing structural space without adding extra height, while improving structural compactness. The anti-negative pressure plate 9 between the first waterproof rib 82 and the internal heat exchanger 5 can completely cover the end of the internal heat exchanger 5, the water receiving tray 8, and the portion of the water receiving tray 8 between the first water-blocking ribs that is close to the internal heat exchange fan 6, thus providing better anti-negative pressure, preventing water blowing, and improving user experience.

[0121] In some embodiments of this application, a mounting part 84 is provided on the side of the waterproof rib facing away from the internal heat exchanger 6, and a through hole 91 is provided on the anti-negative pressure plate 9. The anti-negative pressure plate 9 is fixedly connected to the mounting part 84 by fasteners passing through the through hole 91.

[0122] In this embodiment, the anti-negative pressure plate 9 is fixedly connected by fasteners, which can prevent the anti-negative pressure plate 9 from vibrating and falling off, and adapt to the bumpy environment of the vehicle. At the same time, by providing a mounting part 84 for installing and fixing the anti-negative pressure plate 9 on the side of the first waterproof rib, drilling holes in the bottom of the water receiving tray 8 is avoided, thus preventing the risk of water leakage.

[0123] Fasteners can be screws or bolts; see references for further details. Figure 12 The mounting part 84 can be a screw post. The fastener passes through the through hole 91 and is then connected to the bolt post.

[0124] In some embodiments of this application, the chassis 1 has two annular surrounds 10, one annular surround 10 is located inside the outline of the other annular surround 10, and the bottom end of the heat insulation cover 4 is located at the top end of the two annular surrounds 10.

[0125] In this embodiment, a double-ringed enclosure 10 is provided on the chassis 1, so that the heat insulation cover 4 is located at the top of the ringed enclosure 10, forming a double-sealed structure to reduce heat loss. The double-ringed enclosure 10 improves the heat insulation effect by 15% compared to the single-ringed enclosure 10.

[0126] In some embodiments of this application, one of the two annular enclosures 10 closer to the internal heat exchanger 5 is defined as the first annular enclosure 101, and the other as the second annular enclosure 102. (See reference...) Figure 11 The height of the first annular enclosure 101 is higher than the height of the second annular enclosure 102.

[0127] In this embodiment, by setting the height of the first annular surrounding plate 101 to be higher than the height of the second annular surrounding plate 102, a stepped seal can be formed at the connection between the first annular surrounding plate 101, the second annular surrounding plate 102 and the heat insulation cover 4, which improves the fit between the heat insulation cover 4 and the annular surrounding plate, effectively avoids air leakage problems, and improves the heat insulation effect.

[0128] In addition, the height difference design can form a staggered seal, which can maintain the seal even if the chassis 1 is slightly deformed. This not only adapts to the bumpy conditions of the vehicle, but also reduces the amount of material used and lowers the cost.

[0129] In some embodiments of this application, reference is made to Figure 11 The bottom ends of the first cover 41 and the second cover 42 are provided with flanges 43 that meet, and the flanges 43 are provided with first through holes 44.

[0130] The flange 43 provides a flat pressing surface, and the first through hole 44 facilitates the fastener to pass through and fix, ensuring the overall rigidity of the split insulation cover 4 after splicing.

[0131] The parking air conditioner 100 may include a retaining strip 45, which spans across two flanges 43. (Reference) Figure 11 The pressure strip 45 has a second through hole 451 corresponding to the first through hole 44. The fastener passes through the second through hole 451 and the first through hole 44 and is fixed to the chassis 1, so that the pressure strip 45 presses the first cover 41 and the second cover 42 tightly onto the chassis 1.

[0132] refer to Figure 11 The ends of the first cover 41 and the second cover 42 along their length are joined by flanges 43. A pressure strip 45 spans the flanges 43 and is evenly pressed between the flanges 43 of the two covers by two fasteners to form a rigid overall frame, ensuring the integrity of the segmented insulation cover 4.

[0133] In this embodiment, screw posts 15 are provided on the chassis 1 corresponding to the first through hole 44 and the second through hole 451. (Continue to refer to...) Figure 11 The screw post 15 is located between the first annular plate 101 and the second annular plate 102.

[0134] The first cover 41 and the second cover 42 are detachably connected by the pressure strip 45. Compared with the buckle fixation, it will not loosen due to plastic aging or buckle fatigue under vehicle bumps, sudden braking and high frequency vibration conditions, and the reliability is significantly improved.

[0135] In addition, by setting the pressure strip 45 to simultaneously press the first cover 41 and the second cover 42, the number of parts can be reduced and the assembly process can be simplified. This not only facilitates the disassembly and assembly of the insulation cover 4, but also helps to improve the insulation performance of the insulation cover 4.

[0136] refer to Figure 15 The chassis 1 may include a base plate 14, on which waterproof reinforcing strips and annular surrounding plates are disposed. Two waterproof reinforcing strips, the base plate 14, and portions of the first annular surrounding plates 101 at both ends of the waterproof reinforcing strips form a water receiving tray 8. The waterproof reinforcing strips, the annular surrounding plates 10, and the limiting members 85 may be integrally formed with the base plate 14.

[0137] In this embodiment, the existing waterproof ribs and annular surrounding plate 10 are used as a wall to naturally enclose the water receiving tray 8 with the base plate 14, eliminating the need for a separate injection / stamping water receiving tray 8, reducing mold costs and the number of parts, and achieving structural reuse.

[0138] Multiple limiting members 85 are provided between the first waterproof reinforcing strip 82 and the second waterproof reinforcing strip 83, and the limiting members 85 are located on the base plate 14. (Reference) Figure 13 , Figure 16 The internal heat exchanger 5 is supported on a portion of the base plate 14 between the limiting member 85 and the second waterproof rib 83.

[0139] In this embodiment, the limiting member 85 serves as the positioning reference for the internal heat exchanger 5 in the front-to-back direction on the base plate 14. During assembly, the internal heat exchanger 5 only needs to be pushed down to the bottom to be in place, eliminating the need for additional positioning fixtures and improving assembly efficiency and consistency.

[0140] refer to Figure 16 The portion of the base plate 14 between the first waterproof reinforcing bar 82 and the limiting member 85 is defined as the isolation base plate 141, and the portion of the base plate 14 between the limiting member 85 and the second waterproof reinforcing bar 83 is defined as the supporting base plate 142. (Continue to refer to...) Figure 16 The isolation base plate 141 between the two anti-negative pressure plates 9 protrudes upward relative to the supporting base plate 142 and is raised.

[0141] The isolation base plate 141 between the two anti-negative pressure plates 9 forms a raised area, which can physically isolate condensate and effectively keep water outside the suction area of ​​the inner heat exchanger fan 6. This prevents condensate on the drip tray 8 from being too close to the inner heat exchanger fan 6, thus avoiding condensate being sucked into the inner heat exchanger fan 6 and causing water blowing.

[0142] In some other embodiments, reference is made to Figure 8 The first cover 41 and the second cover 42 are connected to define a through section 46, which is connected to the inner heat exchanger 5, and the inner heat exchanger 5 is installed in the through section 46. The heat insulation cover 4 covers the chassis 1 and its height is not higher than the height of the top surface of the inner heat exchanger 5.

[0143] In this embodiment, by setting a heat insulation cover 4 formed by connecting a first cover 41 and a second cover 42 on the chassis 1, the two together define a through part 46, so that the vertically arranged internal heat exchanger 5 can be directly inserted therein and placed in the internal heat exchange air duct. The heat insulation cover 4 does not cover the internal heat exchanger 5, which not only reduces the height of the heat insulation cover 4, thereby reducing the overall height of the parking air conditioner 100, but also significantly reduces the amount of material used in the heat insulation cover 4 and reduces costs.
