Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a heat exchanger installation structure and an air conditioner. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, air conditioners have become an indispensable household appliance in people's lives. As the technology in the field of household appliances becomes more mature and the competition becomes more fierce, consumers have higher and higher requirements for the quality of air conditioners.

[0003] Conventional air conditioners need to install indoor and outdoor units, which are not very suitable for some special practical scenarios. For this reason, an all-in-one air conditioner came into being, which integrates the functions of the indoor and outdoor units of traditional air conditioners into one shell. In the prior art, the heat exchanger is usually arranged along the width direction of the air conditioner shell, that is, the heat exchanger is perpendicular to the length direction of the air conditioner shell, but due to the thickness limitation of the air conditioner, this installation method results in a small heat exchange area of ​​the heat exchanger and poor heat exchange effect.

[0004] In addition, in the prior art, when installing the heat exchanger, it is generally connected to the bottom plate of the air conditioner shell only by its bottom, and in order to facilitate subsequent maintenance and insertion, it is usually connected by screws. This installation structure is relatively simple; since vibration is inevitable during the use of the air conditioner, the stability of the existing single screw connection structure is subject to certain tests. Utility Model Content

[0007] Compared with the existing technology, the technical effects achieved by adopting this technical solution are:

[0008] In the heat exchanger mounting structure of the utility model, the mounting angle of the heat exchanger which is traditionally arranged perpendicular to the length direction of the heat exchanger shell is adjusted, that is, it is arranged to be inclined along the thickness direction of the air conditioner shell, thereby effectively increasing the heat exchange area and improving the heat exchange efficiency without increasing the thickness dimension of the air conditioner shell. In addition, the bottom of the heat exchanger of this structure is connected to the bottom plate of the air conditioner shell through the lower mounting frame. In addition, corresponding limiting structures are respectively arranged at the left and right ends of the heat exchanger for limiting the position of the heat exchanger, thereby effectively improving the structural stability after the heat exchanger is connected to the air conditioner shell.

[0009] Furthermore, the lower mounting frame is a "J"-shaped structure, the top plate of the lower mounting frame is connected to the lower bottom surface of the heat exchanger, and the two flanges at the open end of the lower mounting frame are connected and fixed to the bottom plate of the air conditioner. In the above structure, the lower mounting frame is a "J"-shaped structure, which is convenient for connection with the heat exchanger and can be detachably connected to the air conditioner housing, and the connection structure is simple and easy to process, and can be formed by integrated sheet stamping.

[0010] As an improvement, a window is provided on the right side wall of the air conditioner housing, and a sunken limiting skirt is provided on the periphery of the window. When the right side panel is installed at the window, the inner side of the right side panel abuts against the limiting skirt, and the outer side is flush with the right side wall of the air conditioner. The limiting skirts at the upper and lower ends of the window are provided with limiting notches, and the upper and lower ends of the right side of the heat exchanger are respectively limited and fitted in the two limiting notches, so that the right side wall of the heat exchanger fits with the inner wall of the right side panel. In the above improved structure,

[0011] As a further improvement, the left and right end faces of the heat exchanger are both outwardly convex arc-shaped surfaces, and the shape of the limiting notch matches the arc-shaped surface.

[0012] As a further improvement, a "U"-shaped upper mounting frame is connected to the top of the heat exchanger, and an open end of the upper mounting frame is close to the top plate of the air conditioner housing, so that a wire passage for passing cables is formed between the upper mounting frame and the top plate.

[0013] In addition, the utility model also provides an air conditioner, which includes any of the above-mentioned heat exchanger installation structures. The air conditioner with this structure increases the heat exchange area and heat exchange efficiency by adjusting the installation angle of the heat exchanger without increasing the thickness of the air conditioner shell.

Based on the embodiment of the utility model, all other embodiments obtained by the current technicians in this field without making creative achievements are within the scope of protection of the utility model.

[0025] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0026] It should be emphasized that the terms "include / comprise / have" when used herein refer to the presence of features, elements, steps or components, but do not exclude the presence or addition of one or more other features, elements, steps or components. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "front and back", "left and right", "upper end", "lower end", etc. are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present utility model and simplifying the description. The actual directions and relative positions of the various components may change accordingly according to the position of the observer.

[0027] like Figures 1 to 7 As shown, the utility model discloses a heat exchanger installation structure, including an air conditioner shell 1, the rear end of the air conditioner shell 1 is the air inlet side, and the front end is the air outlet side. Specifically, a corresponding air inlet channel is arranged on the side panel at the rear end of the air conditioner shell 1, and an air outlet channel is arranged on the front side of the air conditioner shell 1 to ensure air flow.

[0028] A heat exchanger 2 is inside the air conditioner casing 1 and close to the air outlet side, and a lower mounting frame 3 is connected to the lower end of the heat exchanger 2, and the lower mounting frame 3 is detachably connected to the bottom plate of the air conditioner casing 1; a fan mounting plate 4 arranged along its width direction is connected to the air outlet side of the air conditioner casing 1, and a limiting angle is formed between the fan mounting plate 4 and the left side plate of the air conditioner, and the left end of the heat exchanger 2 fits within the limiting angle, and the right end of the heat exchanger 2 is inclined in the direction away from the fan mounting plate 4, and a limiting portion for limiting the right end of the heat exchanger 2 is provided on the right side plate 6 of the air conditioner casing, and the left and right ends of the heat exchanger 2 are respectively abutted against the left and right side plates 6 of the air conditioner casing 1.

[0029] In this structure, the inclined heat exchanger 2 effectively increases the heat exchange area and improves the heat exchange efficiency without changing the width of the air conditioner housing 1; and the installation of the heat exchanger 2 and the air conditioner housing 1 is not only connected by screws at the bottom, but also adds a structure for limiting the left and right ends of the heat exchanger 2; specifically, a fan mounting plate 4 is arranged near the air outlet side in the air conditioner housing 1, and a plurality of vertically arranged fans are installed on the fan mounting plate 4, and a right-angle limiting area is formed between the fan mounting plate 4 and the left side wall of the air conditioner housing 1, and the left end of the heat exchanger 2 is limited in this area. Similarly, a limiting portion for limiting the right end of the heat exchanger 2 is provided on the right side wall of the air conditioner housing 1 to increase the structural strength of the heat exchanger 2 after installation; on the other hand, in this structure, the left and right ends of the heat exchanger 2 are ensured to be in contact with the left and right side panels 6 of the air conditioner housing 1, that is, it is effectively ensured that the air coming in along the rear side of the air conditioner housing 1 can pass through the heat exchanger 2 more completely, thereby improving the heat exchange efficiency and the air conditioning performance.

[0030] In this embodiment, for the convenience of installation, the lower mounting frame 3 is designed as a "J"-shaped structure. Figure 7 As shown, the top plate 3.1 of the lower mounting frame 3 is connected to the lower bottom surface of the heat exchanger 2, and the two flanges 3.2 at the open end of the lower mounting frame 3 are connected and fixed to the bottom plate of the air conditioner through corresponding fasteners. In this structure, the "J"-shaped lower mounting frame 3 can also make the lower end of the heat exchanger 2 have a certain height lifting effect, because in actual use, there will be condensed water at the bottom of the inner cavity of the air conditioner housing 1. In this structure, the lower end surface of the heat exchanger 2 is lifted, so that the condensed water at the bottom can be effectively avoided.

[0031] In addition, in order to facilitate the disassembly and assembly of the parts in the air conditioner housing 1, a window is usually provided on the right side wall of the air conditioner housing 1, and a sunken limiting skirt 5 is provided on the periphery of the window. When the right side plate 6 is installed at the window, the inner side of the right side plate 6 abuts against the limiting skirt 5, and the outer side is flush with the right side wall of the air conditioner, so as to ensure the stable installation of the right side plate 6 and the aesthetic appearance. In practical applications, detachable side plates are generally provided on both sides of the air conditioner housing 1, and only the right side plate 6 is taken as an example for explanation here.

[0032] On the other hand, in the above structure, if Figure 4 , 6 As shown, the limiting notches 7 are provided on the limiting skirt 5 at the upper and lower ends of the right window of the air conditioner housing 1, and the upper and lower ends of the right side of the heat exchanger 2 are respectively limited and matched in the two limiting notches 7, so that the right side wall of the heat exchanger 2 fits with the inner wall of the right side plate 6. Because the sunken limiting skirt 5 structure is set, and after the right side plate 6 is installed, there is a height difference between the inner wall of the limiting skirt 5 on the inner wall of the right side plate 6, so when the heat exchanger 2 is installed, the setting of the limiting notch 7 ensures that the right side wall of the heat exchanger 2 fits and seals with the inner wall of the right side plate 6, thereby improving the air heat exchange efficiency.

[0033] In this embodiment, preferably, Figure 3 , 4 As shown, the left and right end faces of the heat exchanger 2 are both convex arcuate faces 8, and the shape of the limiting notch 7 matches the arcuate face 8. The left and right ends of the heat exchanger 2 are arranged in an arc structure, which is more convenient for sealing with the left and right side walls of the air conditioner.

[0034] In addition, in this embodiment, if Figure 5 As shown, a "U"-shaped upper mounting frame 9 is connected to the top of the heat exchanger 2, and the open end of the upper mounting frame 9 is close to the upper cover plate 10 of the air conditioner housing 1, so that a wire passage for passing cables is formed between the upper mounting frame 9 and the upper cover plate 10, which facilitates the installation of the lines and can hide the lines to avoid the exposure of the cables and cause interference with other components.

[0035] On the other hand, the utility model further provides an air conditioner, which includes any one of the heat exchanger 2 installation structures as described above and can achieve the same effect. To avoid repetition, it will not be described here.

[0036] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
