[0033] The utility model provides an air conditioner 100, please refer to Figures 1 to 4In an embodiment of the present application, the air conditioner 100 includes a housing 10 , a heat exchange module 20 and a fan 30 .

[0034] The shell 10 is provided with an installation cavity 13, and the installation cavity 13 has a front cavity wall and a rear cavity wall arranged opposite to each other. The front cavity wall is formed on a side of the installation cavity 13 away from the wall. The shell 10 is also provided with an air inlet 14 and an air outlet 15 connected to the installation cavity 13 respectively.

[0035] The air conditioner 100 is generally hung on a wall in the room, or is arranged near the wall. The shell 10 can be made of a variety of materials. The part of the shell 10 close to the wall can be made of a material with poor high-temperature resistance and thermal conductivity, and the part of the shell 10 away from the wall can be made of a material with high thermal conductivity, such as metal. In this way, the heat in the installation cavity 13 can be more efficiently transferred to the shell 10 through heat conduction, and the shell 10 then dissipates the heat into the room through thermal radiation.

[0036] The heat exchange module 20 includes front fins 21 and rear fins 22 that are spaced apart. The front fins 21 are fixedly installed in the installation cavity 13 and are attached to the front cavity wall. The rear fins 22 are fixedly installed in the installation cavity 13 and are spaced apart from the rear cavity wall. The front fins 21, the rear fins 22 and the installation cavity 13 together form an air duct.

[0037] There are many ways to fix the front fin 21 and the rear fin 22 in the installation cavity 13. In one setting form, the front fin 21 and the rear fin 22 can be first fixedly connected by a connecting plate, and the front fin 21 and the rear fin 22 are spaced apart, and then fixedly installed in the installation cavity 13. In another setting form, the front fin 21 and the rear fin 22 can be fixedly installed in the installation cavity 13 by connecting plates respectively. Among them, the specific connection method of the front fin 21 and the rear fin 22 installed in the installation cavity 13 can be threaded connection, clamping, welding, etc.

[0038] The front fins 21 and the rear fins 22 are spaced apart, and the rear fins 22 and the rear cavity wall are spaced apart, so that a space for air flow is formed in the installation cavity 13, thereby forming an air duct. In the air duct, the front fins 21 and the rear fins 22 can exchange heat with the air.

[0039] The fan 30 is installed in the installation cavity 13, the air inlet end 31 of the fan 30 is connected to the air inlet 14, the air outlet end 32 of the fan 30 faces the air duct, and the end of the air duct away from the fan 30 is arranged opposite to the air outlet 15. The fan 30 includes but is not limited to a centrifugal fan 30, an axial flow fan 30, a diagonal flow fan 30, a cross flow fan 30, etc. The fan 30 is mainly used to drive the flow of air, so as to drive the air from the air inlet 14 to the air duct, and after flowing through the air duct, it is discharged from the housing 10 through the air outlet 15 and enters the indoor environment.

[0040] The fan 30 can be installed in the installation cavity 13 by threaded connection, clamping connection, etc. In some embodiments, a partition can be provided in the installation cavity 13 to separate a relatively independent space in the installation cavity 13 for the fan 30 to be installed.

[0041] Through the above technical scheme, the utility model fits the front fin 21 to the front cavity wall, and sets the rear fin 22 to be spaced apart from the rear cavity wall. The front fin 21, the rear fin 22 and the installation cavity 13 together form an air duct. The air inlet end 31 of the fan 30 is connected to the air inlet 14, and the air outlet end 32 of the fan 30 faces the air duct, and the end of the air duct away from the fan 30 is arranged opposite to the air outlet 15. With such an arrangement, the fan 30 can drive air to flow from the air inlet 14 into the installation cavity 13, and then be discharged from the shell 10 through the air outlet 15 after passing through the air duct, and enter the indoor environment. When the air flows through the air duct, the air can absorb heat from the opposite sides of the rear fins 22 and the side of the front fins 21 away from the front cavity wall, thereby discharging warm air at the outlet wind to increase the temperature of the indoor environment. At the same time, the front fins 21 transfer the heat to the shell 10 by fitting with the front cavity wall, so that the shell 10 can dissipate the heat into the room by thermal radiation. In this way, the indoor environment temperature can be evenly and quickly increased by warm air, and the thermal radiation of the shell 10 can provide a warm and comfortable sensory experience for the indoor people.

[0042] In some examples, such as Figure 3 As shown, the front fin 21 and the rear fin 22 both include a first fin 211 and a second fin 212, the length of the first fin 211 is greater than the length of the second fin 212, the first fin 211 has a first side 211a and a second side 211b in the length direction, the second fin 212 has a third side 212a and a fourth side 212b in the length direction, the second side 211b is flush with the fourth side 212b, and the fan 30 is also arranged adjacent to the third side 212a.

[0043] In this way, the fan 30 can be embedded in the heat exchange module 20, optimizing the layout of the components in the installation cavity 13 to improve the space utilization in the installation cavity 13. At the same time, the air outlet 32 ​​of the fan 30 can be better connected with the air duct to reduce the wind resistance of the air duct.

[0044] In some examples, such as Figures 1 to 4 As shown, the shell 10 includes a body 11 and a front cover 12 . The body 11 is recessed with a mounting groove 111 . The front cover 12 covers the notch of the mounting groove 111 to form a mounting cavity 13 . The front fin 21 is attached to the side of the front cover 12 facing the mounting groove 111 .

[0045] There are many ways to connect the front cover 12 and the body 11. In one setting form, the front cover 12 is movably installed on one side of the notch of the installation groove 111, and the front cover 12 moves relative to the housing 10 to cover or open the notch of the installation groove 111. In another setting form, the front cover 12 and the body 11 are separately set, and the front cover 12 can be connected to the body 11 by threaded connection, clamping, etc., and covers one side of the notch of the installation groove 111.

[0046] Such an arrangement facilitates the assembly of components in the installation cavity 13 and the processing of parts, thereby improving the production efficiency of the air conditioner 100.

[0047] In some examples, the front fin 21 is connected to the front cover plate 12 via a silicone sheet. This arrangement can improve the heat conduction efficiency between the front fin 21 and the front cover plate 12 to reduce heat loss.

[0048] In some examples, such as Figure 3 and Figure 4 As shown, the mounting groove 111 is provided with a mounting portion 112, and the mounting portion 112 is also extended along the width direction of the rear fin 22, and the rear fin 22 is fixedly connected to the mounting portion 112. In this way, the rear fin 22 is spaced apart from the rear cavity wall by the protruding mounting portion 112, forming a space for air circulation, so as to constitute a part of the air duct, thereby reducing the wind resistance in the air duct.

[0049] In some examples, such as Figure 3 and Figure 4 As shown, the mounting portion 112 includes at least two mounting bars, at least two mounting bars are arranged at intervals along the length direction of the rear fin 22, at least two mounting bars are extended along the width direction of the rear fin 22, and the rear fin 22 is fixedly connected to the mounting bars. Such an arrangement is intended to further reduce the wind resistance in the air duct, and can disperse the connection points between the rear fin 22 and the rear cavity wall to reduce stress concentration.

[0050] Preferred as Figure 3 and Figure 4As shown, please refer to the above contents that both the front fin 21 and the rear fin 22 include the first fin 211 and the second fin 212. In this embodiment, the mounting portion 112 includes three mounting strips. The first side 211a and the second side 211b of the first fin 211 are respectively fixedly connected to the mounting strips located on the two outer sides, and the third side 212a and the fourth side 212b of the second fin 212 are respectively fixedly connected to the two adjacent mounting strips. An end plate is also provided in the middle of the first fin 211, and the end plate is fixedly connected to the mounting strip located in the middle, that is, the end plate of the first fin 211 can be connected to the third side 212a of the second fin 212. In this way, not only can the overall structural stability of the heat exchange module 20 be enhanced, but also the space between the front fin 21 and the rear fin 22 can be separated into two sub-channels through the action of the end plate to provide a guiding effect on the flow of air.

[0051] In some examples, such as Figures 3 to 5 As shown, the heat exchange module 20 also includes a heat exchange pipeline 23, which is used to carry heat exchange medium. The heat exchange pipeline 23 is at least partially embedded in the front fins 21 and the rear fins 22, so that the heat exchange pipeline 23 transfers energy with the front fins 21 and the rear fins 22 respectively.

[0052] In order to improve the heat exchange efficiency of the heat exchange pipeline 23, the heat exchange pipeline 23 can be made of metal copper, and of course, it can also be made of other materials with high thermal conductivity. The heat exchange medium includes but is not limited to Freon, water, etc. The heat exchange pipeline 23 can be connected to the pipeline of the air conditioner 100 external unit to form a circulating heat exchange pipeline 23.

[0053] In some examples, such as Figures 3 to 5 As shown, the heat exchange pipeline 23 includes a first pipeline and a second pipeline, and the first pipeline and the second pipeline are arranged in parallel; wherein the heat exchange medium flows along the first pipeline to the end of the first fin 211 of the front fin 21 close to the fan 30, the end of the first fin 211 of the front fin 21 away from the fan 30, the end of the first fin 211 of the rear fin 22 away from the fan 30, and the end of the first fin 211 of the rear fin 22 close to the fan 30; the heat exchange medium flows along the second pipeline to the end of the second fin 212 of the front fin 21 close to the fan 30, the end of the second fin 212 of the front fin 21 away from the fan 30, the end of the second fin 212 of the rear fin 22 away from the fan 30, and the end of the second fin 212 of the rear fin 22 close to the fan 30.

[0054] With such a configuration, the heat exchange medium with a higher temperature first transfers the heat to the front side of the shell 10, i.e., the front cover 12, through the fins, so that the front cover 12 can dissipate the heat to the room by thermal radiation. The heat exchange medium with a higher temperature drops slightly after heat exchange through the front fins 21, and then the heat exchange medium flows to the rear fins 22, which mainly exchange heat with the air in the air duct. Finally, the air is driven to flow through the fan 30, thereby taking the heat out of the air conditioner 100 and releasing it into the indoor environment, thereby enhancing the indoor people's sensory experience of warmth and comfort.

[0055] In some examples, the heat exchange medium carried by the heat exchange pipeline 23 flows along the heat exchange pipeline 23 in sequence to the end of the front fin 21 close to the fan 30, the end of the front fin 21 away from the fan 30, the end of the rear fin 22 away from the fan 30, and the end of the rear fin 22 close to the fan 30. In this arrangement, compared with the above-mentioned solution in which the heat exchange pipeline includes the first pipeline and the second pipeline, the heat exchange medium in this solution has a single flow direction, which facilitates the installation of the heat exchange pipeline.

[0056] In some examples, such as Figure 1 and Figure 3 As shown, the air inlet 14 includes a return air hole 141 and a fresh air hole 142. The return air hole 141 is exposed in the housing 10, and the fresh air hole 142 is connected to a fresh air pipeline. The fresh air pipeline can be connected to the outside, and the fresh air pipeline can also be connected to a fresh air device.

[0057] like Figure 3 and Figure 4 As shown, please refer to the above contents that the front fin 21 and the rear fin 22 both include the first fin 211 and the second fin 212, the fan 30 is arranged adjacent to the third side 212a, preferably, the return air hole 141 and the fresh air hole 142 are arranged on one side of the housing 10, and are arranged adjacent to each other, so as to facilitate the installation and connection of the fresh air duct, and to be more beautiful. Of course, in other embodiments, the return air hole 141 and the fresh air hole 142 can be arranged in other places, for example, the fresh air hole 142 is arranged on the side of the housing 10 close to the wall, the fresh air duct is directly embedded in the wall, and the return air hole 141 is arranged on the bottom side of the housing 10.

[0058] With such configuration, the air conditioner 100 can circulate and heat the indoor air through the return air holes 141 , and can also introduce new air through the new air holes 142 for heating, so as to improve the quality of the indoor air.

[0059] Among them, filter cotton can be further arranged between the air inlet 14 and the air inlet end 31 of the fan 30 to filter the flowing air. Similarly, filter cotton can be arranged between the air outlet end 32 of the fan 30 and the air duct.

[0060] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
