Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning equipment, and specifically provides a cabinet air-conditioning shell and a cabinet air-conditioning having the same. Background Art

[0002] Cabinet air conditioners (the indoor part of the air conditioner) are widely used by users because of their good cooling and heating effects. Cabinet air conditioners are usually installed on the ground or fixed platforms in homes, offices or other commercial places.

[0003] Existing cabinet air conditioners usually include a housing, a heat exchanger disposed in the housing, a crossflow fan, an air duct assembly, a base, and other components. The housing has an air inlet and an air outlet, the heat exchanger is used to cool or heat the air, and the air duct assembly is used to allow the crossflow fan to drive the air from the air inlet to the air outlet via the heat exchanger.

[0004] In order to facilitate the manufacturing, assembly, etc. of cabinet air conditioners, the existing housing usually includes a front housing and a rear housing. Some current cabinet air conditioners will fix one or more of the heat exchanger, crossflow fan and air duct assembly to the front housing or the rear housing, so that the front housing or the rear housing bears at least part of the weight of the one or more items. However, the weight easily causes the housing to deform in the lateral direction, resulting in a gap at the junction of the front housing and the rear housing, affecting the aesthetics of the cabinet air conditioner.

[0005] In order to overcome the above problems, a transverse support member is currently provided on the front shell or the rear shell to provide a transverse pulling force to the front shell or the rear shell, thereby preventing the shell from deforming in the transverse direction. However, the existing transverse support member and the shell are usually fixed by screws or bolts, which requires workers to hold the transverse support member with one hand to align the transverse support member with the mounting hole on the shell, and tighten the screws or bolts with the other hand. Not only is it easy for the transverse support member to be misplaced during the assembly process, but the assembly is also extremely cumbersome. Utility Model Content

[0006] One purpose of the utility model is to solve the problem of complicated installation of the transverse supporting components in the existing cabinet air conditioner.

[0007] To achieve the above-mentioned object, the utility model provides a housing of a cabinet air conditioner in a first aspect, comprising:

[0008] The first shell is configured to have an arc-shaped or U-shaped cross section, and two transverse end surfaces of the first shell are respectively provided with limited position clamping structures;

[0009] The transverse supporting member has two ends in the length direction respectively provided with limited position snap-fitting structures, so that the transverse supporting member can be snap-fitted with the first shell through the limited position snap-fitting structures.

[0010] Optionally, the position-limiting snap-fit ​​structure includes a recessed groove; and the position-limiting snap-fit ​​matching structure includes a sheet structure matching the recessed groove.

[0011] Optionally, the position-limiting snap-fit ​​structure further includes a protruding structure arranged in the recess; the position-limiting snap-fitting matching structure further includes a position-limiting hole formed on the sheet structure and adapted to the protruding structure, so that the protruding structure is embedded in the position-limiting hole.

[0012] Optionally, the height of the protruding structure and / or the depth of the sinking groove is / are selected from any value between 1 mm and 10 mm.

[0013] Optionally, the height of the protruding structure and / or the depth of the sinking groove is 5 mm; and / or, one end of the protruding structure away from the bottom surface of the sinking groove is provided with a chamfer.

[0014] Optionally, when the protruding structure is concentric with the limiting hole, an annular gap is formed between the peripheral wall of the limiting hole and the protruding structure.

[0015] Optionally, the width of the annular gap is selected from any value between 1 mm and 2 mm.

[0016] Optionally, the width of the annular gap is 1.5 mm.

[0017] Optionally, the first shell is further provided with at least one threaded hole on the bottom wall of the sink, and the sheet structure is provided with at least one through hole, and the through hole is aligned with the threaded hole so that a screw or bolt can pass through the through hole and be tightened with the threaded hole, thereby fixing the lateral support member to the first shell.

[0018] Optionally, the first shell includes a main body and two vertical beams arranged at two ends of the main body in a lateral direction, and the limiting clamping structure is arranged on the vertical beams.

[0019] Optionally, two ends of the body extend to the outside of the vertical beam respectively to shield the vertical beam and the position-limiting snap-fitting structure.

[0020] Optionally, the housing further includes a second shell adapted to the first shell.

[0021] Optionally, the first shell is a rear shell of the cabinet air conditioner, and the second shell is a front shell of the cabinet air conditioner.

[0022] The utility model provides a cabinet air conditioner in a second aspect, comprising the housing described in any one of the first aspects.

[0023] Based on the foregoing description, those skilled in the art can understand that, in the aforementioned technical solution of the utility model, by respectively setting the limiting snap-fitting structures at the two end faces of the first shell in the lateral direction, and respectively setting the limiting snap-fitting structures at the two ends of the lateral support member in the length direction, the lateral support member can be snap-fitted with the first shell through the limiting snap-fitting structures and the limiting snap-fitting structures. The lateral support member and the first shell that are snap-fitted together can at least achieve the preliminary fixation of the lateral support member and the first shell, so that there is no need to manually support the lateral support member, which simplifies the assembly of the lateral support member by workers.

[0024] Furthermore, by making the limiting snap-fit ​​structure include a recessed groove, and making the limiting snap-fit ​​matching structure include a sheet structure matching the recessed groove, the sheet structure can be embedded in the recessed groove, thereby achieving the snap-fit ​​between the lateral support member and the first shell.

[0025] Furthermore, by making the position-limiting clamping structure further include a protruding structure disposed in the recessed groove, making the position-limiting clamping matching structure further include a position-limiting hole formed on the sheet structure and adapted to the protruding structure, and making the protruding structure embedded in the position-limiting hole, the transverse support member and the first shell can be double-clamped. In addition, the protruding structure can also provide a transverse force to the transverse support member, thereby improving the connection strength between the protruding structure and the transverse support member, and further improving the anti-deformation capability of the shell.

[0026] Furthermore, by selecting the height of the protruding structure and / or the depth of the recessed groove to be any value between 1 mm and 10 mm, especially 5 mm, there is a sufficient clamping area between the lateral support member and the first shell, thereby effectively preventing the lateral support member clamped to the first shell from falling off.

[0027] Furthermore, by providing a chamfer at one end of the protruding structure away from the bottom surface of the sink, it is convenient to insert the protruding structure into the limiting hole, and the protruding structure is prevented from scratching the hands of the workers.

[0028] Furthermore, when the protruding structure is concentric with the limiting hole, an annular gap is formed between the peripheral wall of the limiting hole and the protruding structure, thereby avoiding the situation where the first housing and the lateral support member cannot be installed together due to processing errors and deformation. At the same time, the deformation of the first housing is also limited.

[0029] Furthermore, by setting at least one threaded hole on the bottom wall of the sink groove of the first shell and setting at least one through hole on the sheet structure, when the through hole is aligned with the threaded hole, a screw or bolt can pass through the through hole and be tightened with the threaded hole, thereby fixing the lateral support member to the first shell.

[0030] Furthermore, by arranging the limit clamping structure on the vertical beam, the structural strength of the first shell is ensured.

[0031] Furthermore, by extending the two ends of the body to the outside of the vertical beam respectively, the two ends of the body can shield the vertical beam and the position-limiting snap-fitting structure, thereby ensuring the aesthetics of the shell.

[0032] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0044] It should be understood by those skilled in the art that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and the embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0045] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. For example, the terms "install", "connect", "connect" and "fix", unless otherwise specifically described, can specifically be any feasible connection form such as bolt connection, screw connection, welding, plug-in, riveting, melting, and clamping.

[0047] In addition, it should be noted that in the description of the present utility model, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target object (such as an evaporator, air, condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target object will release "heat" while absorbing "cold", and will absorb "heat" while releasing "cold". A certain target object stores "cold" or "heat" in order to keep the current temperature of the target object. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target object (such as an evaporator) will absorb heat while cooling.

[0048] like Figures 1 to 3 As shown, in some embodiments of the present invention, the cabinet air conditioner 001 includes a housing 100 , a heat exchanger 200 , a cross-flow fan 300 , an air duct assembly 400 , a base 500 and a top cover 600 .

[0049] The housing 100 has an air inlet 101 and an air outlet 102 .

[0050] The heat exchanger 200 is disposed in the housing 100 and is used to heat or cool the air in the housing 100 .

[0051] The cross-flow blower 300 is disposed between the heat exchanger 200 and the air outlet 102 on the flow path of the gas.

[0052] The air duct assembly 400 is configured to enable the crossflow fan 300 to drive air from the air inlet 101 to the air outlet 102 via the heat exchanger 200. The air duct assembly 400 includes a volute 410 and a volute tongue 420, which are relatively arranged on both sides of the crossflow fan 300 so that the crossflow fan 300 is located between the volute 410 and the volute tongue 420.

[0053] The base 500 is disposed on the bottom side of the housing 100 , and the top cover 600 is disposed on the top side of the housing 100 .

[0054] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the housing 100 includes a first shell 110 , a second shell 120 and a lateral supporting member 130 .

[0055] The first housing 110 is the rear housing of the cabinet air conditioner 001, and the second housing 120 is the front housing of the cabinet air conditioner 001. The lateral support member 130 is used to provide a pulling force to the first housing 110 and / or the second housing 120 in the lateral direction to limit the lateral deformation of the first housing 110 and / or the second housing 120.

[0056] In addition, in other embodiments of the present invention, those skilled in the art may also transform the first shell 110 into a front shell of the cabinet air conditioner 001 and transform the second shell 120 into a rear shell of the cabinet air conditioner 001 as needed.

[0057] Furthermore, the first shell 110 is fixedly connected to the base 500 or is made in one piece.

[0058] For example, a buckle is provided on the first shell 110 , and a slot is provided on the base 500 , so that the first shell 110 and the base 500 are snap-connected together.

[0059] For another example, the first housing 110 and the base 500 are fixedly connected by bolts or screws.

[0060] Further, the first housing 110 and the second housing 120 are adapted to each other so that the first housing 110 and the second housing 120 can be relatively fixed together. For example, one of the first housing 110 and the second housing 120 is provided with a buckle, and the other is provided with a slot. The buckle is inserted into the slot, and thus the first housing 110 and the second housing 120 are fixed together.

[0061] Furthermore, the top cover 600 is fixedly connected to the second shell 120 or is made in one piece, so that when the second shell 120 and the first shell 110 are fixed together, the top cover 600 is also in contact with the first shell 110 .

[0062] In addition, in other embodiments of the present invention, those skilled in the art may also omit the top cover 600 as needed, and provide a structure on the top side of the second shell 120 that abuts against the top end of the first shell 110 .

[0063] Alternatively, in other embodiments of the present invention, those skilled in the art may also omit the second shell 120 and the top cover 600 as needed, so that the housing 100 only includes the first shell 110 .

[0064] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the first shell 110 is configured to have an arc-shaped or U-shaped cross section, and limited position clamping structures 111 are respectively provided at two lateral end surfaces of the first shell 110 .

[0065] like Figure 5 As shown, in some embodiments of the present invention, two ends of the transverse supporting member 130 in the length direction are respectively provided with limited position snap-fitting structures 131 .

[0066] like Figure 6 and Figure 7 As shown, the lateral support member 130 is snap-fitted to the first housing 110 via the position-limiting snap-fitting structure 131 and the position-limiting snap-fitting structure 111 .

[0067] Those skilled in the art can understand that, by respectively providing the limiting snap-fit ​​structures 111 at the two end surfaces of the first housing 110 in the lateral direction, and respectively providing the limiting snap-fit ​​structures 131 at the two ends in the length direction of the lateral support member 130, the lateral support member 130 can be snap-fitted with the first housing 110 through the limiting snap-fit ​​structures 131 and the limiting snap-fit ​​structures 111. The snap-fitted lateral support member 130 and the first housing 110 can at least achieve the preliminary fixation of the lateral support member 130 and the first housing 110, so that the lateral support member 130 does not need to be supported by hand, which simplifies the assembly of the lateral support member 130 by workers.

[0068] like Figures 4 to 7 As shown, in some embodiments of the present invention, the limiting snap-fit ​​structure 111 includes a recessed groove 1111, and the limiting snap-fitting structure 131 includes a sheet structure 1311 matching the recessed groove 1111, so that the sheet structure 1311 of the limiting snap-fitting structure 131 is embedded in the recessed groove 1111, thereby snapping the lateral support member 130 and the first shell 110 together.

[0069] Furthermore, in some embodiments of the present invention, the position-limiting snap-fit ​​structure 111 further includes a protruding structure 1112 disposed in the sink 1111. The position-limiting snap-fitting structure 131 further includes a position-limiting hole 1312 formed on the sheet structure 1311 and adapted to the protruding structure 1112, so that the protruding structure 1112 is embedded in the position-limiting hole 1312.

[0070] Those skilled in the art can understand that the combination of the sink 1111 and the sheet structure 1311 and the combination of the protruding structure 1112 and the limiting hole 1312 enable the lateral support member 130 to be double-engaged with the first shell 110. In addition, the protruding structure 1112 can also provide a lateral force to the lateral support member 130, thereby improving the connection strength between the protruding structure 1112 and the lateral support member 130, and further improving the anti-deformation capability of the housing 100.

[0071] Further, the height of the protruding structure 1112 and / or the depth of the sinking groove 1111 are selected from any value between 1 mm and 10 mm. For example, the height of the protruding structure 1112 and / or the depth of the sinking groove 1111 can be 1 mm, 3 mm, 5 mm, 8 mm, 10 mm, etc.

[0072] Those skilled in the art will appreciate that by selecting the height of the protruding structure 1112 and / or the depth of the recessed groove 1111 from any value between 1 mm and 10 mm, in particular 5 mm, there is a sufficient clamping area between the lateral support member 130 and the first shell 110, thereby effectively preventing the lateral support member 130 clamped to the first shell 110 from falling off.

[0073] like Figure 4 As shown, in some embodiments of the present invention, a chamfer 11121 can be provided at one end of the protruding structure 1112 away from the bottom surface of the sink 1111 to facilitate the insertion of the protruding structure 1112 into the limiting hole 1312 and prevent the sharp edge of the protruding structure 1112 from scratching the workers' hands.

[0074] like Figure 7 As shown, when the protruding structure 1112 and the limiting hole 1312 are concentric, an annular gap is formed between the peripheral wall of the limiting hole 1312 and the protruding structure 1112. The annular gap can prevent the first housing 110 and the lateral support member 130 from being unable to be installed together due to processing errors and deformation. At the same time, the deformation of the first housing 110 can also be limited.

[0075] Further, the width of the annular gap is selected from any value between 1 mm and 2 mm. For example, the width of the annular gap is 1 mm, 1.5 mm, 1.8 mm, 2 mm, etc.

[0076] The specific value of the width of the annular gap may be determined according to the size and deformation of the first shell 110 .

[0077] like Figure 4 , Figure 5 and Figure 7 As shown, the first housing 110 is further provided with at least one threaded hole 1101 on the bottom wall of the sink 1111. The sheet structure 1311 is provided with at least one through hole 13111, and the through hole 13111 is aligned with the threaded hole 1101, so that a screw or bolt passes through the through hole 13111 and is tightened with the threaded hole 1101, thereby fixing the lateral support member 130 to the first housing 110.

[0078] Those skilled in the art will appreciate that by providing at least one threaded hole 1101 on the bottom wall of the recess 1111 of the first shell 110 and providing at least one through hole 13111 on the sheet structure 1311, when the through hole 13111 is aligned with the threaded hole 1101, a screw or bolt can pass through the through hole 13111 and be tightened with the threaded hole 1101, thereby fixing the lateral support member 130 to the first shell 110.

[0079] Return to view Figure 3 and Figure 4 In some embodiments of the present invention, the first shell 110 includes a main body 112 and two vertical beams 113 arranged at both ends of the main body 112 in the lateral direction, and the limiting clamping structure 111 is arranged on the vertical beams 113 .

[0080] It is understandable to those skilled in the art that, since the vertical beam 113 has a large cross-section and a large structural strength, the structural strength of the first housing 100 is ensured by arranging the limiting clamping structure 111 on the vertical beam 113 .

[0081] like Figure 3 and Figure 4 , Figure 6 and Figure 7 As shown, both ends of the body 112 extend to the outside of the vertical beam 113 respectively to cover the vertical beam 113 and the position-limiting snap-fitting structure 131 , thereby ensuring the aesthetics of the housing 100 .

[0082] like Figure 4 As shown, two sides of the sink 1111 in the vertical direction extend from the vertical beam 113 toward the second shell 120 to ensure that the sink 1111 has a sufficient depth.

[0083] like Figure 5 As shown, the circumferential edge of the transverse support member 130 is provided with a folded edge to improve the structural strength of the transverse support member 130 and increase the contact area between the sheet structure 1311 and the side wall of the sink 1111.

[0084] Furthermore, the circumferential edge of the limiting hole 1312 is also provided with a folded edge to increase the peripheral wall area of ​​the limiting hole 1312 , thereby increasing the contact area between the peripheral wall of the limiting hole 1312 and the protruding structure 1112 .

[0085] like Figures 8 to 10 As shown, in some embodiments of the present invention, the heat exchanger 200 is mounted on the volute 410 , and one lateral end of the heat exchanger 200 abuts against the volute 410 .

[0086] Specifically, a water receiving portion 411 is provided at the bottom end of the volute 410 , and the heat exchanger 200 is placed on the water receiving portion 411 , so that the volute 410 carries the heat exchanger 200 through the water receiving portion 411 and receives condensed water flowing down from the heat exchanger 200 .

[0087] Correspondingly, a fixing plate (not marked in the figure) is provided at the top of the volute 410 for fixing the motor of the cross-flow blower 300 .

[0088] Furthermore, the volute 410 is fixedly connected to the first housing 110 through its water receiving portion 411 and the fixing plate. The fixed connection can be plug-in, snap-on, or screw-on.

[0089] For example, a card slot is provided on the first shell 110, and plug blocks are provided on the water receiving portion 411 and the fixing plate. The plug blocks on the water receiving portion 411 and the fixing plate are respectively inserted into the card slots on the first shell 110, so that the volute 410 and the first shell 110 are fixed together in the vertical direction through the matching connection structure. Furthermore, a threaded hole 1101 can also be provided on the first shell 110, and a through hole 13111 is provided on the water receiving portion 411 and / or the fixing plate. Bolts or screws pass through the through hole 13111 and are tightened with the threaded hole 1101 on the first shell 110, so as to achieve the fixation of the volute 410 and the first shell 110.

[0090] like Figures 8 to 10 As shown, in some embodiments of the present invention, the volute tongue 420 includes a sealing portion 421 extending toward the heat exchanger 200 , so that the volute tongue 420 is sealed and connected to the heat exchanger 200 through the sealing portion 421 .

[0091] It is understood by those skilled in the art that by providing a sealing portion 421 extending toward the heat exchanger 200 on the volute 420, the volute 420 can be sealed and connected to the heat exchanger 200 through the sealing portion 421, thereby avoiding the need to arrange a seal between the volute 420 and the heat exchanger 200, reducing the number of components of the cabinet air conditioner 001, and facilitating the assembly of the cabinet air conditioner 001. In addition, the seal between the volute 420 and the heat exchanger 200 also avoids the wheezing sound when the crossflow fan 300 is in operation.

[0092] like Fig. 9 and Fig.10 As shown, in some embodiments of the present invention, the volute tongue 420 is further provided with a plurality of reinforcing ribs 422 distributed at intervals on the sealing portion 421 .

[0093] Those skilled in the art will appreciate that, in some embodiments of the present invention, by providing a plurality of spaced reinforcing ribs 422 on the sealing portion 421, the structural strength of the sealing portion 421 is enhanced, thereby preventing the sealing portion 421 from being deformed during production, transportation, and assembly.

[0094] Furthermore, the height of the reinforcing rib 422 gradually decreases from the root of the sealing portion 421 toward the heat exchanger 200 .

[0095] Those skilled in the art will appreciate that, in some embodiments of the present invention, by gradually reducing the height of the reinforcing rib 422 from the root of the sealing portion 421 toward the heat exchanger 200, the structural strength of the sealing portion 421 is ensured while reducing the use of materials and facilitating demolding of the volute tongue 420.

[0096] like Fig. 9 and Fig.10As shown, in some embodiments of the present invention, optionally, the outermost two of the plurality of reinforcing ribs 422 are distributed at both ends of the sealing portion 421 in the length direction, and extend from the root of the sealing portion 421 to the end of the sealing portion 421. The other reinforcing ribs 422 except the outermost two of the plurality of reinforcing ribs 422 are distributed between the two ends of the sealing portion 421, and are spaced apart from the end of the sealing portion 421.

[0097] Those skilled in the art will appreciate that, in some embodiments of the present invention, by distributing the two outermost reinforcement ribs 422 at both ends of the length of the sealing portion 421 and extending from the root of the sealing portion 421 to the end of the sealing portion 421, the two ends of the length of the sealing portion 421 have sufficient structural strength, thereby preventing the two ends of the length of the sealing portion 421 from being cracked and damaged due to external forces.

[0098] At the same time, by distributing the other reinforcing ribs 422 except the two outermost ones among the multiple reinforcing ribs 422 between the two ends of the sealing portion 421 and having a gap between the ends of the sealing portion 421, the middle area of ​​the sealing portion 421 has a certain flexibility, so as to ensure that the sealing portion 421 can abut against the heat exchanger 200 when the heat exchanger 200 and the volute tongue 420 are interference fit.

[0099] It should be noted that although the reinforcing rib 422 shown in the figure is located on the side of the sealing portion 421 away from the cross flow blower 300, those skilled in the art may also arrange the reinforcing rib 422 on the side of the sealing portion 421 close to the cross flow blower 300 as needed.

[0100] like Figures 8 to 10 As shown, in some embodiments of the present invention, the heat exchanger 200 is configured as an arc-shaped structure that bends inward toward the cross-flow fan 300 so that the heat exchanger 200 surrounds a portion of the cross-flow fan 300 and covers a larger area on the air inlet side of the cross-flow fan 300.

[0101] like Fig. 9 As shown, in some embodiments of the present invention, the sealing portion 421 abuts against the inner side surface of the heat exchanger 200 to achieve sealing between the volute tongue 420 and the heat exchanger 200 and prevent a gap from appearing between the volute tongue 420 and the heat exchanger 200 .

[0102] It should be noted that, in some embodiments of the present invention, the heat exchanger 200 is a heat exchanger 200 with fins, and the extension direction of the fins can be horizontal, perpendicular to the length direction (up and down direction) of the sealing portion 421. Therefore, at the junction of the volute tongue 420 and the heat exchanger 200, air will also flow through the gaps between adjacent fins.

[0103] It should be further explained that, in the present invention, the sealing portion 421 abuts against the inner side surface of the heat exchanger 200 , and they may be in direct contact with each other, or there may be a small gap between them.

[0104] It should be understood by those skilled in the art that, when ensuring that a large amount of air does not flow through the gap between the sealing portion 421 and the heat exchanger 200, a small gap between the sealing portion 421 and the heat exchanger 200 will not affect the cooling and heating effects of the heat exchanger 200 on the air. Therefore, under the premise that the relative position relationship between the sealing portion 421 and the heat exchanger 200 can prevent air from flowing through the gap between the two, even if there is a small gap between the sealing portion 421 and the heat exchanger 200, it should fall within the protection scope of the present utility model.

[0105] So far, the technical solution of the utility model has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the utility model is not limited to these specific embodiments. Without departing from the technical principle of the utility model, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principle of the utility model will fall within the protection scope of the utility model.

[0106] Finally, it should be noted that in the present invention, the term "communication" means fluid communication, so as to allow fluid (such as air, liquid) to flow between two connected objects. And the "communication" can be to allow the fluid to flow between the two connected objects without leakage, or to allow the fluid to flow between the two connected objects with a little leakage.
