Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and specifically provides a mobile air conditioner. Background Art

[0002] Currently, to improve the convenience of indoor air conditioning, mobile air conditioners have emerged. These are easily movable and installed air conditioning systems, typically designed as standalone units that can be easily moved between rooms when needed. Mobile air conditioners typically include independent outdoor and indoor heat exchange chambers. The outdoor heat exchange chamber primarily houses components such as a compressor, condenser, and outdoor fan, while the indoor heat exchange chamber primarily houses components such as an evaporator and indoor fan. The compressor, evaporator, and condenser are connected by refrigerant pipelines to circulate the refrigerant. When the refrigerant flows to the evaporator, it primarily exchanges heat with the air delivered to the indoor heat exchange chamber to regulate the indoor air temperature. When the refrigerant flows to the condenser, it primarily exchanges heat with the air delivered to the outdoor heat exchange chamber to cool the refrigerant. The heat-exchanged air is then discharged outdoors.

[0003] In the related art, the outdoor heat exchange cavity has a chassis, and the condenser is fixedly installed on the chassis. However, during the installation process or the movement of the mobile air conditioner, the condenser is prone to flipping, resulting in poor sealing effect. Utility Model Content

[0004] The utility model aims to solve the above technical problem, that is, to solve the problem of poor sealing of the condenser of the mobile air conditioner.

[0005] The utility model provides a mobile air conditioner, comprising: an outer shell, comprising a chassis, the chassis comprising at least a bottom plate and a first enclosure and a second enclosure opposite to each other; a water storage tank, arranged on the bottom plate, comprising an annular side groove wall constructed in a stepped shape, the annular side groove wall comprising a high-order groove wall and a low-order groove wall, a first vertical rib is provided between the annular side groove wall and the first enclosure, and a second vertical rib is provided between the annular side groove wall and the second enclosure; an outdoor heat exchanger, the portion close to the annular side groove wall is installed on the low-order groove wall and abuts against the high-order groove wall, the outdoor heat exchanger comprises a first side end corresponding to the first enclosure and a second side end corresponding to the second enclosure, the first side end is provided with a first tube sheet, and the second side end is provided with a second tube sheet, wherein the first tube sheet abuts against the inner side surface of the first vertical rib, and the second tube sheet abuts against the inner side surface of the second vertical rib.

[0006] When the above technical solution is adopted, by installing the outdoor heat exchanger on the low-order groove wall and abutting it against the high-order groove wall, the stepped annular side groove wall can be used to achieve sealing and positioning of the bottom end of the outdoor heat exchanger; further, by limiting the bottom end of the first tube sheet by the first vertical rib set between the annular side groove wall and the first enclosure, and limiting the bottom end of the second tube sheet by the second vertical rib set between the annular side groove wall and the second enclosure, the bottom ends of the first side end and the second side end of the outdoor heat exchanger can be further clamped and fastened, which can avoid shaking of the outdoor heat exchanger, thereby minimizing the occurrence of inversion of the outdoor heat exchanger and ensuring the sealing effect of the outdoor heat exchanger. In addition, the first vertical rib and the second vertical rib can also play a positioning role to improve installation efficiency.

[0007] In an optional embodiment of the above-mentioned mobile air conditioner, the annular side groove wall has at least two oppositely arranged long side groove walls extending between the first enclosure and the second enclosure, and a third vertical rib and a fourth vertical rib are respectively provided at both ends of the long side groove wall; the inner side surface of the third vertical rib and the inner side surface of the fourth vertical rib are both in contact with the outdoor heat exchanger.

[0008] In this way, through the arrangement of the third vertical rib and the fourth vertical rib, on the one hand, they can cooperate with the first vertical rib and the second vertical rib to achieve the positioning function during the installation of the outdoor heat exchanger; on the other hand, they can achieve the limiting function of the outdoor heat exchanger, thereby further avoiding the shaking of the bottom end of the outdoor heat exchanger between the two long side groove walls, reducing the occurrence of inverted sheets, and improving the sealing effect.

[0009] In an optional embodiment of the above-mentioned mobile air conditioner, the outdoor heat exchanger has an outdoor heat exchange tube and a heat exchange fin sleeved on the heat exchange tube, the annular side groove wall also has two short side groove walls corresponding to the first enclosure and the second enclosure respectively, the bottom end surface of the heat exchange fin is lower than the end surface of the low-step groove wall of the short side groove wall, and the first tube sheet and the second tube sheet are respectively abutted against the end surface of the low-step groove wall of the corresponding short side groove wall.

[0010] In this way, the sealing performance of the side portions of the outdoor heat exchanger corresponding to the first enclosure plate and the second enclosure plate in the water storage tank can be improved.

[0011] In an optional embodiment of the above-mentioned mobile air conditioner, it also includes an indoor fan arranged on the air outlet side of the outdoor heat exchanger, and the indoor fan includes: a fan volute, including a mounting plate matching the shape of the outdoor heat exchanger, and the mounting plate is provided with a first side edge arranged vertically and extending toward the outdoor heat exchanger, and the first side edge abuts against the first tube sheet; wherein, the mounting plate is provided with a fan inlet.

[0012] The fan volute is located on the outlet side of the outdoor heat exchanger, driving air through the outdoor heat exchanger to exchange heat with the outdoor heat exchanger. The heat-exchanged air then enters the outdoor fan through the fan inlet. By providing a first side edge on the mounting plate that is arranged vertically and extends toward the outdoor heat exchanger, and by abutting the first side edge against the outdoor heat exchanger and the first tube sheet, a flow gap is created between the outdoor heat exchanger and the outdoor fan to improve the fluidity of the airflow to the outdoor fan. Furthermore, the first tube sheet and the first side edge can achieve surface contact, thereby increasing the stability of the connection between the two and further enhancing the sealing effect of the outdoor heat exchanger on that side.

[0013] In an optional embodiment of the above mobile air conditioner, the first side is screwed to the first tube sheet.

[0014] In this way, the connection or disassembly between the first tube sheet and the fan volute can be achieved with a relatively simple structure.

[0015] In an optional embodiment of the above-mentioned mobile air conditioner, the mounting plate is also provided with a second side edge arranged vertically and extending toward the outdoor heat exchanger, and the second side edge is connected to a bent side edge extending toward the second enclosure; the second tube plate has a bent side plate bent and extended toward the second enclosure, and the bent side edge abuts against the bent side plate.

[0016] In this way, by setting the second side, a flow gap can be left between the outdoor heat exchanger and the outdoor fan to improve the fluidity of the airflow to the outdoor fan. On the other hand, through the surface contact between the bent side and the bent side plate, the surface contact between the second side and the second tube plate can be achieved, thereby improving the stability of the connection between the two and further improving the sealing effect of the outdoor heat exchanger on this side.

[0017] In an optional implementation scheme of the above mobile air conditioner, the bent side is connected to the bent side panel by screws.

[0018] In this way, the connection or disassembly between the second tube sheet and the fan volute can be achieved with a relatively simple structure.

[0019] In an optional embodiment of the above-mentioned mobile air conditioner, the mounting plate is further provided with a third side connected between the first side and the second side, and the third side cover is provided on the top end of the outdoor heat exchanger, and a gap is formed between the third side and the first tube sheet and the second tube sheet.

[0020] In this way, by setting the third side, the top of the outdoor heat exchanger can be sealed; at the same time, gaps are formed between the third side and the first tube sheet and the second tube sheet, which can reserve space for the fin reversal to prevent the sealing from being damaged after reversing.

[0021] In an optional implementation scheme of the above-mentioned mobile air conditioner, it also includes: a partition plate, which is arranged inside the outer shell and abuts against the top end of the outdoor heat exchanger; a first stop rib, which is arranged on the side of the partition plate facing the outdoor heat exchanger, and the stop rib extends along the length direction of the outdoor heat exchanger and abuts against the windward side of the outdoor heat exchanger.

[0022] In this way, by setting the partition plate, the internal space of the shell can be separated. The partition plate is set at the top of the outdoor heat exchanger, and by setting the first stop rib on the side of the partition plate facing the outdoor heat exchanger, the top of the windward side of the outdoor heat exchanger can be sealed, preventing air from bypassing the outdoor heat exchanger and flowing directly to the outdoor fan.

[0023] In an optional implementation scheme of the above-mentioned mobile air conditioner, it also includes: a second stop rib, which is arranged at the end of the first stop rib corresponding to the first side end, and extends toward the air outlet side of the outdoor heat exchanger, and the second stop rib abuts against the first side end; a third stop rib, which is arranged at the end of the first stop rib corresponding to the second side end, and extends toward the air outlet side of the outdoor heat exchanger, and the third stop rib abuts against the second side end.

[0024] Thus, by providing the second stop rib, the top end of the first side end of the outdoor heat exchanger can be sealed; by providing the third stop rib, the top end of the second side end of the outdoor heat exchanger can be sealed.

[0025] In an optional embodiment of the above mobile air conditioner, the second stop rib is connected to the first tube sheet via a first connecting piece; and the third stop rib is connected to the second tube sheet via a second connecting piece.

[0026] In this way, the installation stability of the first tube sheet and the second tube sheet and the sealing performance with respect to the outdoor heat exchanger can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Combine Figures 1 to 8 As shown, the present invention provides a mobile air conditioner, comprising a housing 100, a water storage tank 200, and an outdoor heat exchanger 300. The housing 100 comprises a chassis 110, which comprises at least a bottom plate 111 and a first enclosure 112 and a second enclosure 113 opposite to each other. The water storage tank 200 is disposed on the bottom plate 111 and comprises an annular side groove wall 210 constructed in a stepped shape. The annular side groove wall 210 comprises a high-step groove wall 211 and a low-step groove wall 212. A first vertical rib 114 is provided between the annular side groove wall 210 and the first enclosure 112, and a second vertical rib 115 is provided between the annular side groove wall 210 and the second enclosure 113. The part of the outdoor heat exchanger 300 close to the annular side groove wall 210 is installed on the low-order groove wall 212 and abuts against the high-order groove wall 211. The outdoor heat exchanger 300 includes a first side end 310 corresponding to the first enclosure 112 and a second side end 320 corresponding to the second enclosure 113. The first side end 310 is installed with a first tube sheet 311, and the second side end 320 is installed with a second tube sheet 321, wherein the first tube sheet 311 abuts against the inner side surface of the first vertical rib 114, and the second tube sheet 321 abuts against the inner side surface of the second vertical rib 115.

[0046] Optionally, the mobile air conditioner includes a housing 100, wherein the interior of the housing 100 defines a cavity, the cavity including an outdoor heat exchange cavity and an indoor heat exchange cavity that are independent of each other. Further, the upper half of the housing 100 can be configured as the indoor heat exchange cavity, and the lower half can be configured as the outdoor heat exchange cavity.

[0047] The outdoor heat exchange chamber is equipped with a compressor, an outdoor heat exchanger 300, and an outdoor fan 400. The housing 100 includes at least a chassis 110, on which the compressor, outdoor heat exchanger 300, and outdoor fan 400 are mounted. Optionally, the housing is provided with an outdoor air inlet and an outdoor air outlet corresponding to the outdoor heat exchange chamber. The compressor, outdoor heat exchanger 300, and outdoor fan 400 are sequentially positioned between the outdoor air inlet and the outdoor air outlet along the air flow path, thereby enabling heat exchange between the outdoor air and the refrigerant in the outdoor heat exchanger 300. Both the outdoor air inlet and the outdoor air outlet are connected to the outdoor environment.

[0048] Optionally, the housing 100 is further provided with an air supply port corresponding to the outdoor heat exchange cavity. The air supply port can be connected to the indoor environment to introduce indoor air to ensure the air intake of the outdoor heat exchange cavity.

[0049] Optionally, a water tank 200 corresponding to the outdoor heat exchanger 300 is provided on the chassis 110. The water tank 200 is used to store water, and can cool the condenser when the outdoor heat exchanger 300 is used as a condenser. The outdoor heat exchanger 300 is arranged in the water tank 200. The outdoor heat exchanger 300 is installed vertically, and the water tank 200 includes an annular side groove wall 210 extending vertically. The annular side groove wall 210 is arranged around the circumference of the outdoor heat exchanger 300. By constructing the annular side groove wall 210 into a stepped shape of a high-order groove wall 211 and a low-order groove wall 212, and installing the outdoor heat exchanger 300 on the low-order groove wall 212, so that the circumferential surface of the outdoor heat exchanger 300 near the bottom end abuts against the high-order groove wall 211, the bottom end of the outdoor heat exchanger 300 can be limited. In addition, the provision of the high-step tank wall 211 can also prevent water in the water tank 200 from overflowing.

[0050] Optionally, the chassis 110 further includes a first enclosure 112 and a second enclosure 113 arranged in opposition, and the outdoor heat exchanger 300 includes a first side end 310 and a second side end 320 corresponding to the first enclosure 112 and the second enclosure 113. During installation, transportation, or movement, the first side end 310 and the second side end 320 of the outdoor heat exchanger 300 are prone to shaking, thereby causing the heat exchange fins of the outdoor heat exchanger 300 to tilt. In this way, the bottom end sealing effect of the outdoor heat exchanger 300 will be poor. The first tube sheet 311 provided at the first side end 310 can achieve a sealing effect on the first side end 310; and the second tube sheet 321 provided at the second side end 320 can achieve a sealing effect on the second side end 320.

[0051] In order to ensure the sealing effect of the first tube sheet 311 and the second tube sheet 321, a first vertical rib 114 is provided between the portion of the annular side groove wall 210 facing the first enclosure 112 and the first enclosure 112. The first tube sheet 311 abuts against the inner side surface of the first vertical rib 114, so that the first tube sheet 311 is clamped between the outdoor heat exchanger 300 and the first vertical rib 114, thereby improving the stability of the bottom end of the first tube sheet 311. On the one hand, it can reduce the problem of the outdoor heat exchanger 300 being reversed, and on the other hand, it can improve the tightness of the connection between the first tube sheet 311 and the outdoor heat exchanger 300, thereby improving the sealing. The second tube sheet 321 abuts against the second vertical rib 115; similarly, the second vertical rib 115 is provided between the portion of the annular side groove wall 210 facing the second enclosure 113 and the second enclosure 113, and the second tube sheet 321 abuts against the inner side surface of the second vertical rib 115, so that the second tube sheet 321 is clamped between the outdoor heat exchanger 300 and the second vertical rib 115 to improve the stability of the bottom end of the second tube sheet 321. On the one hand, it can reduce the problem of flipping of the outdoor heat exchanger 300, and on the other hand, it can improve the tightness of the connection between the second tube sheet 321 and the outdoor heat exchanger 300, thereby improving the sealing.

[0052] Optionally, at least two first vertical ribs 114 are provided to enhance the stability of the first tube sheet 311. Optionally, the annular side groove wall 210 includes a short annular side groove wall facing the first enclosure plate 112, with two first vertical ribs 114 disposed at each end of the short annular side groove wall. Furthermore, a first connecting rib 118 is provided between the two first vertical ribs 114. The first connecting rib 118 is screwed to the first tube sheet 311 to further enhance the stability and sealing effect of the installation of the first tube sheet 311.

[0053] Optionally, at least two second vertical ribs 115 are provided to enhance the stability of the second tube sheet 321. The annular side groove wall 210 also includes another short annular side groove wall facing the first enclosure plate 112. Two second vertical ribs 115 are provided at each end of this short annular side groove wall. Furthermore, a second connecting rib 119 is provided between the two second vertical ribs 115. The second connecting rib 119 is screwed to the first tube sheet 311 to further enhance the stability and sealing effect of the second tube sheet 321 during installation.

[0054] Optionally, the water tank 200 is integrally formed on the chassis 110, that is, the annular side tank wall 210 is integrally formed with the chassis 110, and the chassis 110 casing serves as the bottom tank wall of the water tank 200. In this way, the complexity of the structure can be reduced and the structural strength can be improved.

[0055] Alternatively, the water tank 200 is independently provided and fixedly connected to the chassis 110 by welding, gluing, screws, etc. The specific connection method can be determined according to the materials of the chassis 110 and the water tank 200. At the same time, the corresponding water tank 200 can be installed according to different outdoor heat exchangers 300 to improve the applicability of the housing 100.

[0056] When the above technical solution is adopted, by installing the outdoor heat exchanger 300 on the low-step groove wall 212 and abutting the high-step groove wall 211, the stepped annular side groove wall 210 can be used to seal and fix the bottom end of the outdoor heat exchanger 300. Furthermore, by clamping the first tube sheet 311 with the first vertical rib 114 provided between the annular side groove wall 210 and the first enclosure 112, and clamping the second tube sheet 321 with the second vertical rib 115 provided between the annular side groove wall 210 and the second enclosure 113, the first side end 310 and the second side end 320 of the outdoor heat exchanger 300 can be further clamped and fastened, thereby preventing the outdoor heat exchanger 300 from shaking, thereby minimizing the risk of the outdoor heat exchanger 300 flipping over, and ensuring the sealing effect of the outdoor heat exchanger 300. In addition, the first vertical rib 114 and the second vertical rib 115 also have a positioning effect, thereby improving installation efficiency.

[0057] In an optional embodiment of the above-mentioned mobile air conditioner, the annular side groove wall 210 has at least two oppositely arranged long side groove walls 2101 extending between the first enclosure 112 and the second enclosure 113, and the two ends of the long side groove wall 2101 are respectively provided with a third vertical rib 116 and a fourth vertical rib 117; the inner side surface of the third vertical rib 116 and the inner side surface of the fourth vertical rib 117 are both in contact with the outdoor heat exchanger 300.

[0058] In this way, through the arrangement of the third vertical rib 116 and the fourth vertical rib 117, on the one hand, they can cooperate with the first vertical rib 114 and the second vertical rib 115 to achieve the positioning function during the installation of the outdoor heat exchanger 300, and on the other hand, they can achieve the limiting function of the outdoor heat exchanger 300, thereby further avoiding the shaking of the bottom end of the outdoor heat exchanger 300 between the two long side groove walls 2101, reducing the occurrence of inversion, and improving the sealing effect.

[0059] Optionally, the annular side groove wall 210 has two oppositely arranged long side groove walls 2101 and two oppositely arranged short annular side groove walls, the two short annular side groove walls are arranged corresponding to the first enclosure 112 and the second enclosure 113 respectively, and the two long side groove walls 2101 are respectively connected between the two short annular side groove walls.

[0060] Wherein, third vertical ribs 116 and fourth vertical ribs 117 are provided at both ends of the two long side groove walls 2101 .

[0061] The provision of the first and second vertical ribs 114, 115 not only secures the first and second tube sheets 311, 321, but also guides and positions the installation of the outdoor heat exchanger 300. Furthermore, the provision of third and fourth vertical ribs 116, 117 on the long side channel walls 2101, facing the ends of the first and second enclosures 112, 113, respectively, further limits the outdoor heat exchanger 300, preventing the bottom end of the outdoor heat exchanger 300 from shaking near the end of the water storage tank 200, thereby improving the stability and sealing of the outdoor heat exchanger 300.

[0062] Alternatively, the third vertical rib 116 and the fourth vertical rib 117 are not provided.

[0063] Alternatively, a fifth vertical rib may be provided between the third vertical rib 116 and the fourth vertical rib 117. The fifth vertical rib abuts against the outdoor heat exchanger 300 to improve the stability of the outdoor heat exchanger.

[0064] Optionally, one or more supporting ribs are provided between the two long side groove walls 2101 , and the supporting ribs extend along the extension direction of the long side groove walls 2101 to support the outdoor heat exchanger 300 and improve the stability and safety of the outdoor heat exchanger 300 .

[0065] In an optional embodiment of the above-mentioned mobile air conditioner, the outdoor heat exchanger 300 has an outdoor heat exchange tube and a heat exchange fin sleeved on the heat exchange tube. The annular side groove wall 210 also includes two short side groove walls corresponding to the first enclosure 112 and the second enclosure 113 respectively. The bottom end surface of the heat exchange fin is lower than the end surface of the low-step groove wall 212 of the short side groove wall. The first tube sheet 311 and the second tube sheet 321 are respectively abutted against the end surface of the low-step groove wall 212 of the corresponding short side groove wall.

[0066] In this way, the sealing performance of the side portions of the outdoor heat exchanger 300 corresponding to the first enclosing plate 311 and the second enclosing plate 321 in the water storage tank 200 can be improved.

[0067] In the aforementioned alternative embodiment of the mobile air conditioner, the mobile air conditioner further comprises an outdoor fan 400 disposed on the air outlet side of the outdoor heat exchanger 300. The outdoor fan 400 comprises a fan volute 410. The fan volute 410 comprises a mounting plate 411 that matches the shape of the outdoor heat exchanger 300. The mounting plate 411 has a first side 4111 arranged vertically and extending toward the outdoor heat exchanger 300. The first side 4111 abuts against the first tube sheet 311. The mounting plate 411 is provided with a fan inlet 4112.

[0068] The fan volute 410 is located on the outlet side of the outdoor heat exchanger 300 and is used to drive air through the outdoor heat exchanger 300 to exchange heat with the outdoor heat exchanger 300. The heat-exchanged air enters the outdoor fan 400 through the fan inlet 4112. A first side edge 4111 is provided on the mounting plate 411, extending vertically toward the outdoor heat exchanger 300. The first side edge 4111 abuts the outdoor heat exchanger 300 and the first tube sheet 311. This allows for a flow gap between the outdoor heat exchanger 300 and the outdoor fan 400, thereby improving the flow of air to the outdoor fan 400. Furthermore, the first tube sheet 311 and the first side edge 4111 can achieve surface contact, thereby increasing the stability of the connection between the two and enhancing the sealing effect of the outdoor heat exchanger 300 on that side.

[0069] Optionally, the outdoor fan 400 includes a fan volute 410, a fan rotor, and a drive motor. Driven by the drive motor, the fan rotor rotates, thereby driving air flow. The outdoor fan 400 is located on the outlet side of the outdoor heat exchanger 300, and the compressor is located on the windward side of the outdoor heat exchanger 300. This arrangement ensures effective heat dissipation for the compressor.

[0070] The fan volute 410 includes a first volute and a second volute that are connected to each other. Together, the first and second volutes enclose the installation and operating space for the outlet rotor. The first volute is positioned toward the outdoor heat exchanger 300 and is fixedly connected to the outdoor heat exchanger 300. Optionally, the first volute includes a mounting plate 411 and an arc-shaped volute 412. The mounting plate 411 is fixedly connected to the outdoor heat exchanger 300.

[0071] Optionally, a fan inlet 4112 is provided on the mounting plate 411. Air that exchanges heat with the outdoor heat exchanger 300 enters the outdoor fan 400 through the fan inlet 4112. The mounting plate 411 is provided with a first side edge 4111 extending toward the outdoor heat exchanger 300. The first side edge 4111 abuts the side of the outdoor heat exchanger 300 facing the outdoor fan 400. This creates a certain gap between the first side end 310 of the outdoor heat exchanger 300 and the outdoor fan 400 to ensure sufficient airflow. Furthermore, the first side edge 4111 extends in the same direction as the first tube sheet 311, and one side abuts the first tube sheet 311. This creates surface contact between the first side edge 4111 and the first tube sheet 311, resulting in a larger contact area and improved connection stability, thereby ensuring vertical sealing and stability of the first side end 310.

[0072] Optionally, both sides of the mounting plate 411 are fixedly connected to the housing 100 to separate the outdoor heat exchange cavity into a heat exchange space and an air outlet space. The heat exchange space is provided with a compressor and an outdoor heat exchanger 300, and the air outlet space is provided with an outdoor fan 400.

[0073] In an optional embodiment of the mobile air conditioner, the first side 4111 is connected to the first tube plate 311 by screws.

[0074] In this way, the connection or disassembly between the first tube sheet 311 and the fan volute 410 can be achieved with a relatively simple structure.

[0075] Optionally, screw holes that can cooperate with each other are respectively provided on the first side 4111 and the first tube plate 311 so that the two can be fixedly connected by screws.

[0076] Alternatively, the first side 4111 and the first tube plate 311 may be connected by plugging, clamping, welding or gluing.

[0077] Alternatively, the first side 4111 is not provided.

[0078] In an optional embodiment of the above-mentioned mobile air conditioner, the mounting plate 411 is also provided with a second side edge 4113 arranged vertically and extending toward the outdoor heat exchanger 300, and the second side edge 4113 is connected to a bent side edge 4114 extending toward the second enclosure 113; the second tube sheet 321 has a bent side plate 3211 bent and extended toward the second enclosure 113, and the bent side edge 4114 abuts against the bent side plate 3211.

[0079] In this way, by setting the second side 4113, a flow gap can be left between the outdoor heat exchanger 300 and the outdoor fan 400 to improve the fluidity of the airflow to the outdoor fan 400. On the other hand, through the surface contact between the bent side 4114 and the bent side plate 3211, the second side 4113 can be connected to the surface of the second tube plate 321, thereby improving the stability of the connection between the two and further improving the sealing effect of the outdoor heat exchanger 300 at this side end.

[0080] Optionally, the width of the second side 4113 is the same as the width of the first side 4111, so that the distance from the first side end 310 to the mounting plate 411 is equal to the distance from the second side end 320 to the mounting plate 411. In this way, the distance between the outdoor heat exchanger 300 as a whole and the mounting plate 411 can be made equal to ensure the distance between the outdoor heat exchanger 300 as a whole and the mounting plate 411, thereby ensuring the fluidity of air from the outdoor heat exchanger 300 to the outdoor fan 400.

[0081] Optionally, by providing a bent side edge 4114 extending toward the second enclosure 113 on the second side edge 4113, and providing the second tube sheet 321 with a bent side plate 3211 bent and extending toward the second enclosure 113, the bent side edge 4114 and the bent side plate 3211 are in surface contact and abutment with each other. In this way, the connection between the mounting plate 411 and the second tube sheet 321 can be achieved through the bent structure, thereby improving the stability of the connection and ensuring the sealing effect of the second side end of the outdoor heat exchanger 300.

[0082] In an optional implementation scheme of the above mobile air conditioner, the bent side edge 4114 is screwed to the bent side panel 3211 .

[0083] In this way, the connection or disassembly between the second tube sheet 321 and the fan volute 410 can be achieved with a relatively simple structure.

[0084] Optionally, screw holes that can cooperate with each other are respectively provided on the bent side edge 4114 and the bent side plate 3211, so that the two can be fixedly connected by screws.

[0085] Alternatively, the bent side edge 4114 and the bent side plate 3211 may be connected by plugging, snapping, welding or gluing.

[0086] Alternatively, the bent side edge 4114 is not provided. Alternatively, the second side edge 4113 and the bent side edge 4114 are not provided.

[0087] In an optional implementation scheme of the above-mentioned mobile air conditioner, the mounting plate 411 is also provided with a third side 4115 connected between the first side 4111 and the second side 4113. The third side 4115 is covered on the top of the outdoor heat exchanger 300, and a gap is formed between the first tube sheet 311 and the second tube sheet 321.

[0088] In this way, by setting the third side 4115, the top of the outdoor heat exchanger 300 can be sealed; at the same time, gaps are formed between the third side 4115 and the first tube sheet 311 and the second tube sheet 321, which can reserve space for the heat exchange fins of the outdoor heat exchanger to be folded back to prevent the sealing from being damaged after folding.

[0089] Alternatively, the third side 4115 is not provided.

[0090] In the aforementioned alternative embodiment of the mobile air conditioner, the mobile air conditioner further includes a partition plate 500 and a first stop rib 510. The partition plate 500 is disposed within the housing 100 and abuts the top end of the outdoor heat exchanger 300. The first stop rib 510 is disposed on the side of the partition plate 500 facing the outdoor heat exchanger 300. The first stop rib 510 extends along the length of the outdoor heat exchanger 300 and abuts the windward side of the outdoor heat exchanger 300.

[0091] In this way, by setting the partition plate 500, the internal space of the shell 100 can be separated. The partition plate 500 is set at the top of the outdoor heat exchanger 300. By setting the first stop rib 510 on the side of the partition plate 500 facing the outdoor heat exchanger 300, the top of the windward side of the outdoor heat exchanger 300 can be sealed, preventing air from bypassing the outdoor heat exchanger 300 and flowing directly to the outdoor fan 400.

[0092] The length direction of the outdoor heat exchanger 300 is the direction from the first enclosing plate 112 to the second enclosing plate 113 .

[0093] Optionally, the provision of the partition plate 500 can separate the interior of the housing 100 into an indoor heat exchange chamber and an outdoor heat exchange chamber. Specifically, an outdoor heat exchange chamber is formed between the chassis 110 and the partition plate 500. In order to ensure that air flows through the outdoor heat exchanger 300 and then flows to the outdoor fan 400, the outdoor heat exchanger 300 abuts against the partition plate 500. However, it is inevitable that a gap will be formed between the top of the outdoor heat exchanger 300 and the partition plate 500. In order to eliminate the obstruction of the gap, a first stop rib 510 is provided on the side of the partition plate 500 facing the outdoor heat exchanger 300, that is, the first stop rib 510 is provided on the windward side of the outdoor heat exchanger 300 and abuts against the top of the outdoor heat exchanger 300 to prevent air from entering the gap between the outdoor heat exchanger 300 and the partition plate 500.

[0094] In addition, the first stop rib 510 can also play a certain positioning and limiting role, thereby improving the installation efficiency of the outdoor heat exchanger 300.

[0095] Alternatively, the first stopping rib 510 is not provided.

[0096] In the optional embodiment of the mobile air conditioner, a second stop rib 520 and a third stop rib 530 are further included. The second stop rib 520 is disposed at the end of the first stop rib 510 corresponding to the first side end 310 and extends toward the air outlet side of the outdoor heat exchanger 300, abutting the first side end 310. The third stop rib 530 is disposed at the end of the first stop rib 510 corresponding to the second side end 320 and extends toward the air outlet side of the outdoor heat exchanger 300, abutting the second side end 320.

[0097] In this way, by setting the second stop rib 520, the top end of the first side end 310 of the outdoor heat exchanger 300 can be sealed; by setting the third stop rib 530, the top end of the second side end 320 of the outdoor heat exchanger 300 can be sealed, thereby improving the sealing effect of the outdoor heat exchanger 300.

[0098] In addition, the second stop rib 520 can also play a role in positioning and limiting the first side end 310, and the third stop rib 530 can also play a role in positioning and limiting the second side end 320, thereby improving the installation efficiency of the outdoor heat exchanger 300.

[0099] Alternatively, the second stop rib 520 is not provided.

[0100] Alternatively, the third stop rib 530 is not provided.

[0101] Alternatively, the second stopping rib 520 and the third stopping rib 530 are not provided.

[0102] In an optional embodiment of the above mobile air conditioner, the second stop rib 520 is connected to the first tube sheet 311 through a first connecting piece; the third stop rib 530 is connected to the second tube sheet 321 through a second connecting piece.

[0103] In this way, the installation stability of the first tube sheet 311 and the second tube sheet 321 and the sealing performance of the outdoor heat exchanger 300 can be improved.

[0104] Optionally, the first connecting member is a screw, that is, the second stopping rib 520 is screw-connected to the first tube plate 311. Alternatively, the second stopping rib 520 is connected to the first tube plate 311 by snap-fitting, plugging, welding, or gluing.

[0105] Optionally, the second connecting member is a screw, that is, the third stopping rib 530 is screw-connected to the second tube sheet 321. Alternatively, the third stopping rib 530 is connected to the second tube sheet 321 by snap-fitting, plugging, welding, or gluing.
