Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioning equipment, and in particular to a heat exchange device capable of performing heat exchange between indoor and outdoor air. Background Art

[0002] The existing heat exchange device with heat exchange function can make the fresh air sucked in from the outside and the air exhausted from the room exchange energy through the heat exchange element or other heat exchange components, so as to adjust the temperature of the fresh air and provide fresh air with suitable temperature for the room. This air conditioning device has the characteristics of low energy consumption, so it is increasingly recognized by consumers. In order to facilitate the inspection of the components inside the heat exchange device installed on the ceiling, an inspection port for inspection is generally provided on the bottom surface of the heat exchange device facing the indoor side, and a detachable inspection port cover for covering the opening. When the heat exchange device is used for a long time in a high humidity environment, such as during the rainy weather in the subtropical south, high humidity air is continuously sucked into the heat exchange device, and the air condenses to produce water. Even if a water-absorbing sponge is provided inside the heat exchange device, when the amount of accumulated water exceeds the water absorption capacity of the water-absorbing sponge, it is possible to flow out from the gap between the inspection port cover and the bottom surface to the ceiling below the heat exchange device, and in addition to damaging the ceiling, it may also flow through the ceiling into the room, affecting the user's experience.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0032] The following orientation or positional relationship is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present disclosure. Specifically, relative to the above, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0034] Figure 1A A schematic diagram of the structure of an inspection port cover plate of a heat exchange device according to an embodiment of the present disclosure installed at the inspection port is shown. Figure 1B A schematic diagram of the structure of a heat exchange device in which an inspection port cover is disassembled from an inspection port according to an embodiment of the present disclosure is shown. Figure 1C Schematically shows the Figure 1B Schematic diagram of the cross section along line AA.

[0035] like Figure 1A , Figure 1B and Figure 1C As shown, the heat exchange device 100 includes a frame 10 for accommodating heat exchange components, such as heat exchange components including a heat exchange core, a fan, a compressor and other components (not shown).

[0036] The frame 10 comprises a frame bottom wall 11, a frame top wall (not shown) and a frame side wall 12, wherein the frame bottom wall 11 and the frame top wall are arranged opposite to each other, and the frame side wall 12 is used to connect the frame bottom wall 11 and the frame top wall, for example, the frame side wall 12 connects the peripheral edge of the frame bottom wall and the frame top wall. In the present embodiment, the frame 10 is in the shape of a cuboid. In an optional embodiment, the frame can be any shape that meets the design.

[0037] When the heat exchange device is installed, the frame bottom wall 11 is located at the lower side in the vertical direction, and the frame top wall is located at the upper side in the vertical direction. The frame bottom wall 11 is provided with an inspection port 13, which is an opening for inspection. The inspection port 13 is provided with an inspection port cover plate 20, which can be removed from the inspection port 13, so that maintenance personnel can inspect and repair the components inside the heat exchange device 100 through the inspection port 13. The frame side wall 12 is provided with a vent 121, so that air can enter the heat exchange device or the air inside the heat exchange device can be discharged through the vent 121, and the number of the vent 121 can be multiple.

[0038] Figure 2 The schematic diagram of the structure of the first peripheral wall around the inspection port of a heat exchange device according to an embodiment of the present disclosure is shown schematically. The heat exchange device further includes a first peripheral wall and a second peripheral wall.

[0039] like Figure 1A and Figure 2 As shown, in the present embodiment, the first circumferential wall 30 is extended from the bottom wall of the frame toward the top wall of the frame, so that there is a certain height between the top end of the first circumferential wall 30 and the bottom wall 11 of the frame, and the first circumferential wall 30 is located on the peripheral side of the inspection port 13, that is, the first circumferential wall 30 extends in the vertical direction, and the first circumferential wall 30 is arranged around the inspection port 13 in the circumferential direction of the inspection port 13.

[0040] In some optional embodiments of the present disclosure, the second peripheral wall is extended from the bottom wall of the frame toward the top wall of the frame. The so-called extension from the bottom wall of the frame to the top wall of the frame means that the second peripheral wall extends in the direction from the bottom wall of the frame to one side of the top wall of the frame, or extends from the top wall of the frame to one side of the bottom wall of the frame, that is, the second peripheral wall can be integrally connected to the bottom wall of the frame at one end, or can extend from one side of the bottom wall of the frame to one side of the top wall of the frame. There is a certain height between the top of the second peripheral wall and the bottom wall of the frame, and the second peripheral wall surrounds the first peripheral wall, that is, the second peripheral wall extends in the vertical direction, and the second peripheral wall is arranged around the first peripheral wall. The first peripheral wall, the second peripheral wall and the bottom wall of the frame together form a first accommodating space for accommodating accumulated water.

[0041] The first peripheral wall is a wall with a vertical portion that is closed around the inspection port, and the second peripheral wall is a wall with a vertical portion that is closed around the first peripheral wall. The first peripheral wall, the second peripheral wall and the bottom wall of the frame are fixedly connected to form a first accommodation space that can accommodate accumulated water generated by condensation. From a vertical direction, the first accommodation space is in the shape of a "U" character, the first peripheral wall is in the shape of a "mouth" character on the inside, and the second peripheral wall is in the shape of a "mouth" character on the outside. When the heat exchange device inhales fresh air from the outside or discharges old air from the room, when the humidity in the air is high, such as during the plum rain weather, the air condenses in the heat exchange device. When the condensation is large, a large amount of accumulated water is generated. The first accommodation space for accommodating accumulated water is formed by the first peripheral wall, the second peripheral wall and the bottom wall of the frame, which can accommodate more accumulated water.

[0042] In some embodiments of the present disclosure, the vent 121 disposed on the frame side wall 12 is communicated with the first accommodation space.

[0043] When there is a lot of accumulated water, if it is not cleaned in time, the first storage space will be full of water, which will cause the accumulated water to seep out from the inspection port and flow out from the ceiling where the heat exchange device is installed, damaging the ceiling and flowing into the room, affecting the user experience.

[0044] In this regard, the heat exchange device 100 in this embodiment connects the vent 121 set on the side wall 12 of the frame with the first storage space. When air enters the heat exchange device 100 from the vent 121, or the air in the heat exchange device 100 is discharged from the vent 121, the air can come into contact with the accumulated water in the first storage space, thereby accelerating the evaporation of the accumulated water in the first storage space, and bringing part of the accumulated water out of the heat exchange device 100 in the form of evaporation, thereby achieving the effect of timely cleaning the accumulated water in the first storage space and effectively avoiding the problem of accumulated water seepage.

[0045] In other optional embodiments of the present disclosure, the accumulated water in the first accommodation space may be drained by providing a drainage hole or other structures in the first accommodation space.

[0046] like Figure 1AAs shown, in this embodiment, the second peripheral wall is connected to the frame side wall 12 to form at least a part of the frame side wall 12, that is, the frame side wall 12 is fixedly connected to the frame bottom wall 11, and the frame side wall 12 is arranged around the frame bottom wall 11 to form a closed area. The minimum spacing D1 between the vent 121 on the frame side wall 12 and the frame bottom wall 11 is greater than the minimum height D2 from the first peripheral wall 30 to the frame bottom wall 11. That is, by setting the spacing D1 to be greater than the height D2, when there is a lot of accumulated water in the first accommodating space, when the height of the accumulated water exceeds the minimum height D2 from the first peripheral wall 30 to the frame bottom wall 11, the accumulated water can overflow the first peripheral wall 30 and enter the inspection port 13. At the same time, through this arrangement, it is possible to prevent the accumulated water from overflowing from the vent 121.

[0047] In this embodiment, the second peripheral wall is connected to the frame side wall 12 to form at least a portion of the frame side wall 12 , so that the first accommodation space can be maximized to accommodate more accumulated water formed by condensation.

[0048] In an optional embodiment of the present disclosure, the second peripheral wall may be a wall having a vertical portion extending from the bottom wall of the frame toward the top wall of the frame, and the second peripheral wall is arranged around the first peripheral wall, so that the first accommodation space can also be formed. For example, the second peripheral wall is arranged between the first peripheral wall and the side wall of the frame, and the minimum height D3 from the second peripheral wall to the bottom wall of the frame is greater than the minimum height D2 from the first peripheral wall to the bottom wall of the frame. By setting the height D3 to be greater than the height D2, when the accumulated water exceeds the maximum water capacity of the first accommodation space, the accumulated water can overflow the first peripheral wall and enter the inspection port. At the same time, through this arrangement, the problem of accumulated water overflowing over the second peripheral wall can be avoided.

[0049] Figure 3 Schematically shows the Figure 2 Schematic diagram of the cross-sectional structure of line BB in . Figure 4 Schematically shows Figure 3 A partial enlarged view of the middle M area. Figure 5 Schematically shows Figure 3 A local enlarged view of the middle N area.

[0050] like Figure 3 As shown, the frame bottom wall 11 includes a bending portion 111 bent toward the frame top wall direction, and the bending portion 111 is used to fix the frame bottom wall 11 and the frame side wall 12, and the bending portion 111 forms at least a part of the second peripheral wall. In the present embodiment, the bending portion 111 forms the second peripheral wall, and is fixedly connected to the frame side wall 12, so that the second peripheral wall forms a part of the frame side wall 12. The bending portion 111 and the frame bottom wall 11 are manufactured by an integral molding process, and the bending portion 111 and the frame side wall 12 can be connected by screws or by welding. By providing the bending portion 111, the strength of the frame bottom wall 11 can be effectively improved.

[0051] In other embodiments, the second peripheral wall may also extend completely from the bottom wall of the housing to connect to the top wall of the housing, thereby forming the entire side wall of the housing.

[0052] As shown in FIG. 1B, the heat exchange device further includes an inspection port cover plate 20.

[0053] The inspection port cover plate 20 is used to cover the inspection port 13. Specifically, when the inspection port cover plate 20 covers the inspection port 13, it can close the inspection port 13 to prevent accumulated water from seeping out of the inspection port 13. The inspection port cover plate 20 is detachably connected to the bottom wall 11 of the housing.

[0054] For example, the inspection port cover plate 20 is installed from the lower side direction of the bottom wall 11 of the housing to the inspection port 13, thereby closing the inspection port 13. When inspection is required, as Figure 1B shown, the inspection port cover plate 20 is detached from the lower side of the inspection port 13, so as to maintain the components inside the heat exchange device 100.

[0055] Figure 6 Schematically shows a three-dimensional structural view of the inspection port cover plate of the heat exchange device according to an embodiment of the present disclosure.

[0056] In this embodiment, as Figure 1B , Figure 4 and Figure 6 shown, the inspection port cover plate 20 includes a cover plate bottom wall 21 and a cover plate side wall 22.

[0057] For example, the cover plate side wall 22 extends from the cover plate bottom wall 21 toward the side of the top wall of the housing, or extends from the cover plate bottom wall 21 away from the side of the top wall of the housing.

[0058] The cover plate side wall 22 and the cover plate bottom wall 21 together form a second accommodation space for accommodating accumulated water. Viewed from the vertical direction, the second accommodation space on the inspection port cover plate 20 is in the shape of a "mouth", so as to cooperate with the "mouth" shape inside the "return" shape of the first accommodation space. When the inspection port cover plate 20 is installed at the inspection port 13, it can cover and close the inspection port 13 to prevent the accumulated water in the heat exchange device 100 from seeping out from the inspection port.

[0059] In this embodiment, the cover plate side wall 22 protrudes and extends from the cover plate bottom wall 21 toward the side of the top wall of the housing, and together with the cover plate bottom wall, forms a second accommodation space.

[0060] In other alternative embodiments of the present disclosure, the cover plate side wall may also extend from the cover plate bottom wall toward the side away from the top wall of the housing, that is, together with the part of the cover plate bottom wall located on the inner peripheral side of the cover plate side wall, form a second accommodation space that is in a sunken state relative to the part of the cover plate bottom wall located on the outer peripheral side of the cover plate side wall.

[0061] Furthermore, in this embodiment, the cover plate side wall 22 protrudes and extends from the outer periphery of the cover plate bottom wall 21 toward one side of the frame top wall to expand the volume of the second accommodation space as much as possible, thereby accommodating more accumulated water. In other optional embodiments of the present disclosure, the cover plate side wall can also be located on the inner peripheral side of the outer periphery of the cover plate bottom wall.

[0062] As described above, when condensation occurs on the components above the inspection port 13, the condensation water drips downward. Since a second storage space is provided on the inspection cover 20, the condensation water can accumulate in the second storage space, thereby preventing the condensation water from leaking from between the inspection cover and the bottom wall of the frame into the room. Alternatively, when there is a lot of accumulated water in the first storage space, and the height of the accumulated water exceeds the minimum height from the first peripheral wall to the bottom wall of the frame, it can overflow the first peripheral wall and enter the inspection port 13. Since a second storage space is formed on the inspection port cover 20, it can accommodate more accumulated water, thereby effectively preventing the accumulated water in the heat exchange device 100 from leaking from the inspection port 13 into the room.

[0063] In an embodiment of the present disclosure, the vent 121 is connected to the second storage space so that the air flowing through the vent 121 can come into contact with the accumulated water in the second storage space, thereby accelerating the evaporation of the accumulated water and discharging the accumulated water in the second storage space out of the heat exchange device in time through air flow.

[0064] In other optional embodiments of the present disclosure, structures such as drainage holes may be provided in the second accommodation space so that the accumulated water can be drained out of the second accommodation space.

[0065] like Figure 4 and Figure 5 As shown, the frame 10 further includes a connecting portion 40 , and the connecting portion 40 is used to connect the frame bottom wall 11 and the inspection port cover plate 20 .

[0066] The connecting portion 40 includes a bottom wall extension edge 41 extending from the first peripheral wall to the inner peripheral side of the inspection port, and a cover plate extension edge 42 protruding and extending from the outer peripheral edge of the bottom wall of the cover plate to the inner peripheral side or the outer peripheral side of the bottom wall of the cover plate. In the installed state, the bottom wall extension edge 41 overlaps with the cover plate extension edge 42. Overlapping means that in the installed state, the bottom wall extension edge 41 and the cover plate extension edge 42 overlap at least partially in the vertical direction. In this embodiment, the cover plate extension edge 42 protrudes and extends toward the outer peripheral side of the bottom wall 21 of the cover plate, and the bottom wall extension edge 41 protrudes and extends from the upper end of the first peripheral wall 30 to the inner peripheral side of the inspection port 13. In other embodiments, the bottom wall extension edge may also be protruding and extending from other positions of the first peripheral wall. Alternatively, the bottom wall extension edge extends toward the inner peripheral side of the inspection port, and the cover plate extension edge extends toward the inner peripheral side of the bottom wall of the cover plate.

[0067] When condensation water drips onto the connection between the inspection port cover 20 and the bottom wall 11 of the frame, or when accumulated water overflows from the first peripheral wall 30 to the inner side of the inspection port 13 to the connection between the inspection port cover 20 and the bottom wall 11 of the frame, since the bottom wall extended edge 41 and the cover extended edge 42 are at least partially overlapped in the vertical direction, the airtightness between the inspection port cover 20 and the bottom wall 11 of the frame is enhanced, thereby suppressing the leakage of accumulated water from the connection between the inspection port cover and the bottom wall of the frame.

[0068] like Figure 4 and Figure 5 As shown, the bottom wall extension edge 41 includes a first bottom wall extension edge 411 and a second bottom wall extension edge 412 disposed opposite to the first bottom wall extension edge 411. The cover plate extension edge 42 includes a first cover plate extension edge 421 and a second cover plate extension edge 422 disposed opposite to the first cover plate extension edge 421. The first bottom wall extension edge 411 is fixedly engaged with the first cover plate extension edge 421, and the second bottom wall extension edge 412 is fixedly engaged with the second cover plate extension edge 422 via a fastener 410.

[0069] The connecting portion 40 further includes a snap-fit ​​rib 43. The snap-fit ​​rib 43 protrudes and extends from a side of the first peripheral wall 30 where the first bottom wall extension edge 411 is provided toward the inner peripheral side of the inspection port 13, and is arranged at a certain distance from the first bottom wall extension edge 411. A certain distance is arranged between the first bottom wall extension edge 411 and the snap-fit ​​rib 43 to accommodate the first cover plate extension edge 421.

[0070] like Figure 4 As shown, when the inspection port cover 20 is installed on the frame bottom wall 11, the first cover extension edge 421 is engaged between the first bottom wall extension edge 411 and the engagement rib 43, thereby achieving engagement and fixation between the first bottom wall extension edge 411 and the first cover extension edge 421.

[0071] like Figure 5 As shown, when the inspection port cover 20 is installed on the frame bottom wall 11, the second cover extension edge 422 overlaps and contacts the second bottom wall extension edge 412 and is connected and fixed by fasteners, such as screws and nuts.

[0072] As a result, the inspection port cover is tightly connected to the bottom wall of the frame body and the installation cost is reduced.

[0073] In the embodiment of the present disclosure, the cover side wall 22 is disposed on the outer periphery of the cover bottom wall 21. The cover extension edge 42 protrudes and extends from the end of the cover side wall 22 toward the inner periphery or the outer periphery of the cover bottom wall 21.

[0074] In one embodiment, the extended edge of the cover plate protrudes and extends from the end of the side wall of the cover plate toward the inner peripheral side of the bottom wall of the cover plate, so that the second accommodating space can be made larger when the size of the inspection port is constant.

[0075] like Figure 5 In the illustrated embodiment, the cover plate extension edge 42 protrudes and extends from the end of the cover plate side wall 22 toward the outer peripheral side of the cover plate bottom wall 21 .

[0076] In some embodiments of the present disclosure, the vent 121 includes an air inlet for air to enter the heat exchange device, and an air outlet for air to be discharged from the heat exchange device.

[0077] For example, the vent 121 includes an air inlet, and air enters the heat exchange device from outside the heat exchange device through the air inlet and contacts the accumulated water in the first storage space and / or the second storage space, so that the evaporated accumulated water is carried out of the heat exchange device along with the flow of air.

[0078] For another example, the vent 121 includes an air outlet, and air is discharged from the heat exchange device through the air outlet. Before the air is discharged, the air comes into contact with the accumulated water in the first storage space and / or the second storage space, so that the evaporated accumulated water is brought out of the heat exchange device through the flow of air.

[0079] According to the embodiments of the present disclosure, by providing a first accommodating space and / or a second accommodating space, accumulated water generated by condensation can be accommodated, and at the same time, by connecting the vents to the first accommodating space and / or the second accommodating space, the air flowing through the vents can come into contact with the accumulated water in the first accommodating space and / or the second accommodating space, thereby promoting the evaporation of the accumulated water, thereby clearing the accumulated water from the heat exchange device, and effectively preventing the problem of accumulated water leaking from the heat exchange device.

[0080] So far, the embodiments of the present disclosure have been described in detail in conjunction with the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the present disclosure.

[0081] It should be noted that the implementation methods not shown or described in the drawings or the text of the specification are all forms known to ordinary technicians in the relevant technical field and are not described in detail. In addition, the above definitions of each element are not limited to the various specific structures and shapes mentioned in the embodiments, and ordinary technicians in the field can simply change or replace them.
