[0038] The indoor unit 10 of the air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0039] like Figures 1-7 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention includes an evaporator 100, an air guide plate 200 and a first heat conduction device 300.

[0040] The evaporator 100 includes an evaporator body 110 and a refrigerant outlet pipe 120, which is connected to the evaporator body 110. A heat dissipation device 210 is provided on the air guide plate 200. The heat dissipation device 210 is configured to transfer absorbed heat to the air guide plate 200. A first heat conduction device 300 is disposed between the refrigerant outlet pipe 120 and the heat dissipation device 210, so that heat on the refrigerant outlet pipe 120 can be transferred to the heat dissipation device 210 through the first heat conduction device 300. In other words, the heat generated by the refrigerant outlet pipe 120 can be conducted to the heat dissipation device 210 through the first heat conduction device 300, and the heat dissipation device 210 then conducts the heat to the air guide plate 200.

[0041] It is understandable that the refrigerant in the refrigerant outlet pipe 120 is the refrigerant that has flowed through the evaporator body 110. In other words, the refrigerant in the refrigerant outlet pipe 120 has already exchanged heat with the air that has passed through the evaporator body 110. The temperature of the refrigerant in the refrigerant outlet pipe 120 is relatively high, so the first heat conduction device 300 conducts the heat of the refrigerant outlet pipe 120 to the heat dissipation device 210 to avoid condensation on the air guide plate 200 due to the large temperature difference.

[0042] Compared with related technologies, the indoor unit 10 of the air conditioner in this embodiment includes an evaporator 100, an air guide plate 200, and a first heat conduction device 300. A heat dissipation device 210 is provided on the air guide plate 200, and the heat dissipation device 210 is connected between the refrigerant outlet pipe 120 of the evaporator 100 and the heat dissipation device 210. Since the temperature of the refrigerant outlet pipe 120 is relatively high, the first heat conduction device 300 conducts the heat of the refrigerant outlet pipe 120 to the heat dissipation device 210, so as to avoid condensation on the air guide plate 200 due to the large temperature difference, thereby improving the user experience.

[0043] The indoor unit 10 of this embodiment is an embedded indoor unit. That is to say, the indoor unit 10 of this embodiment can be installed on a cabinet or a cabinet on an interior wall to conceal the indoor unit 10 in appearance, making the indoor unit 10 of this embodiment more aesthetically pleasing.

[0044] The indoor unit 10 of this embodiment of the air conditioner also includes a housing 400. An air outlet 401 is provided on the lower part of the front surface of the housing 400, and an air inlet 402 is also provided on the front surface of the housing 400. The air inlet 402 is located above the air outlet 401. The evaporator 100 is disposed inside the housing 400, and the air guide plate 200 is disposed at the air outlet 401. During assembly of the indoor unit 10 of this embodiment, both the air outlet 401 and the air inlet 402 face the open side of the cabinet or cupboard, so that the air outlet 401 and the air inlet 402 can smoothly discharge and inhale air, respectively.

[0045] The evaporator 100 also has a refrigerant inlet pipe connected to the evaporator body 110, the inner diameter of which is smaller than the inner diameter of the refrigerant outlet pipe 120. The evaporator body 110 has at least one refrigerant outlet, each refrigerant outlet is connected to a connecting pipe, and each connecting pipe is connected to the refrigerant outlet pipe 120. That is, the refrigerant enters the evaporator body 110 sequentially through the refrigerant inlet pipe, so that the refrigerant exchanges heat with the airflow passing through the evaporator body 110. After heat exchange, the refrigerant then flows through the refrigerant outlet and the connecting pipe into the refrigerant outlet pipe 120. The structure is simple and easy to manufacture.

[0046] In some embodiments, such as Figures 2-4 As shown, the first heat-conducting device 300 includes a sleeve 310 and a heat-conducting element 320, both of which are made of heat-conducting material. The sleeve 310 is fitted onto the refrigerant outlet pipe 120. One end of the heat-conducting element 320 is thermally connected to the sleeve 310, and the other end is thermally connected to the heat dissipation device 210. In other words, one end of the heat-conducting element 320 is thermally connected to the refrigerant outlet pipe 120 through the sleeve 310, so that the heat generated by the refrigerant outlet pipe 120 is conducted to the heat dissipation device 210 through the heat-conducting element 320. The structure is simple and the manufacturing cost is low.

[0047] The heat-conducting element 320 and the sleeve 310 are made of a heat-conducting material, such as copper, aluminum nitride, or graphite. The thermal conductivity of the material of the heat-conducting element 320 and the sleeve 310 is greater than or equal to 100 W / (m·K).

[0048] Furthermore, such as Figure 6 and Figure 7 As shown, the sleeve 310 includes two half-pipes 311 and a connecting plate 312. The two half-pipes 311 are arranged opposite each other, forming an installation space. Each half-pipe 311 contacts and abuts against the refrigerant outlet pipe 120, with the inner wall of each half-pipe 311 contacting and abutting against the outer surface of the refrigerant outlet pipe 120. The two half-pipes 311 can also be disassembled to facilitate the removal of the sleeve 310 from the refrigerant outlet pipe 120.

[0049] There are two connecting plates 312, which are respectively connected to the two half-pipes 311. The two connecting plates 312 are arranged in parallel and fixedly connected. That is, one connecting plate 312 can be fixedly connected to the other connecting plate 312 so that the two half-pipes 311 are fixed to the refrigerant outlet pipe 120 through the two connecting plates 312.

[0050] In some alternative embodiments, one connecting plate 312 has a threaded hole and the other connecting plate 312 has a through hole. The two connecting plates 312 are fixed by threaded fasteners (e.g., screws or bolt assemblies), which makes installation convenient.

[0051] A heat-conducting plate 313 is provided at one end of the heat-conducting component 320. The heat-conducting plate 313 is disposed between the two connecting plates 312 and is in contact with and abuts against the two connecting plates 312. That is to say, the heat-conducting plate 313 is placed between the two connecting plates 312 so that the heat on the two half-tubes 311 can be evenly conducted to the heat-conducting plate 313, and then conducted to the heat-conducting component 320 by the heat-conducting plate 313, thereby improving the heat conduction effect of the first heat-conducting device 300.

[0052] In some embodiments, such as Figure 7 As shown, the heat-conducting plate 313 is connected to one end of the heat-conducting element 320 via multiple heat-conducting strips 330. Each heat-conducting strip 330 is sequentially and spaced apart along the extension direction of the refrigerant outlet pipe 120, connecting one end of the heat-conducting plate 313 to the heat-conducting element 320. Connecting the heat-conducting element 320 and the heat-conducting plate 313 via multiple heat-conducting strips 330 reduces the thermal resistance between them, thereby enabling the first heat-conducting device 300 to better conduct heat from the refrigerant outlet pipe 120 to the heat dissipation device 210, further preventing condensation from forming on the air guide plate 200 due to large temperature differences.

[0053] The heat-conducting strip 330 is made of a thermally conductive material, such as copper, aluminum nitride, or graphite. The thermal conductivity of the material in the heat-conducting strip 330 is greater than or equal to 100 W / (m·K).

[0054] In some embodiments, a heat insulation layer is provided on the outer side of the first heat-conducting device 300, that is, the heat insulation layer is made of a heat-insulating material. For example, the heat insulation layer is made of rubber; or, the heat insulation layer is made of polyurethane. This prevents excessive heat dissipation from the first heat-conducting device 300 before it is conducted to the heat dissipation device 210, thereby ensuring the heat conduction effect of the first heat-conducting device 300.

[0055] In some embodiments, such as Figure 8 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention further includes a fan, a motor 500, and a second heat-conducting device 510. The motor 500 is configured to drive the fan to rotate. The second heat-conducting device 510 is disposed between the sleeve 310 and the motor 500, and is configured to transfer the heat generated by the motor 500 to the sleeve 310. Thus, the heat generated by the motor 500 during operation is conducted to the sleeve 310 by the second heat-conducting device 510, and then sequentially through the sleeve 310 and the first heat-conducting element 320 to the heat dissipation device 210, thereby further increasing the temperature of the heat dissipation device 210, improving the heating effect of the heat dissipation device 210, preventing condensation on the air guide plate 200, and improving the heat dissipation effect of the motor 500 through the second heat-conducting device 510.

[0056] Specifically, the second heat-conducting device 510 is made of a strip-shaped heat-conducting material. One end of it is connected to the sleeve 310, and the other end is connected to the housing of the motor 500. The heat generated by the motor 500 is conducted to the sleeve 310 through the second heat-conducting device 510. The structure is simple and easy to manufacture.

[0057] In other embodiments, such as Figure 8As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention further includes a fan, a motor 500, and a third heat-conducting device 520. The motor 500 is configured to drive the fan to rotate. The third heat-conducting device 520 is disposed between the refrigerant outlet pipe 120 and the motor 500, and is configured to transfer the heat generated by the motor 500 to the refrigerant outlet pipe 120. The portion of the refrigerant outlet pipe 120 connected to the third heat-conducting device 520 is upstream of the portion connected to the first heat-conducting device 300. Thus, the third heat-conducting device 520 conducts the heat from the motor 500 to the refrigerant outlet pipe 120, and then the heat is conducted to the first heat-conducting device 300 through the refrigerant outlet pipe 120. The heat is then conducted sequentially through the first heat-conducting device 300 to the heat dissipation device 210, further increasing the temperature of the heat dissipation device 210, improving the heating effect of the heat dissipation device 210, preventing condensation on the air guide plate 200, and further improving the heat dissipation effect of the motor 500 through the second heat-conducting device 510.

[0058] Specifically, the third heat-conducting device 520 is made of strip-shaped heat-conducting material. One end of it is connected to the sleeve 310, and the other end is connected to the housing of the motor 500. The heat generated by the motor 500 is conducted to the first heat-conducting device 300 through the third heat-conducting device 520. The structure is simple and easy to manufacture.

[0059] In some embodiments, such as Figure 5 As shown, the heat dissipation device 210 includes a plurality of first heat-conducting wires 211, one end of which is connected to a heat-conducting device, and each first heat-conducting wire 211 extends along the length of the air guide plate 200. This allows the first heat-conducting wires 211 to be distributed along the length of the air guide plate 200, enabling the heat conducted by the first heat-conducting device 300 to be conducted to the entire air guide plate 200 through the first heat-conducting wires 211, thereby ensuring that condensation does not occur on the air guide plate 200 of the indoor unit 10 of the air conditioner due to a large temperature difference with the ambient temperature.

[0060] Furthermore, such as Figure 5 As shown, the heat dissipation device 210 also includes a plurality of second heat-conducting wires 212. Each second heat-conducting wire 212 extends along the width direction of the air guide plate 200 and is connected to a plurality of first heat-conducting wires 211 to form a heat dissipation mesh. This allows the second heat-conducting wires 212 to be distributed across the air guide plate 200 along its width direction, so that the heat conducted by the first heat-conducting device 300 can be conducted to the entire air guide plate 200 through the first heat-conducting wires 211 and the second heat-conducting wires 212. This ensures that the air guide plate 200 of the indoor unit 10 of the air conditioner will not condense due to a large temperature difference with the ambient temperature.

[0061] The heat-conducting element 320 is a third heat-conducting wire. The cross-sectional area of ​​the third heat-conducting wire is greater than or equal to the sum of the cross-sectional areas of the multiple first heat-conducting wires 211, thereby reducing the thermal resistance between the heat-conducting element 320 and the multiple first heat-conducting wires 211.

[0062] In some embodiments, the outer surface of the air guide plate 200 is flat, and the inner surface of the air guide plate 200 is concave, so that the thickness of the air guide plate 200 first decreases and then increases along the width direction of the air guide plate 200, or first decreases, remains constant, and then increases. A heat dissipation device 210 is disposed on the outer surface of the air guide plate 200, near the thinnest point of the air guide plate 200. That is, the thickness of the air guide plate 200 at both ends in its width direction is greater than the thickness of its middle part, so that the air guide plate 200 guides the airflow upwards, preventing cold air from blowing in.

[0063] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
