[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0023] An embodiment of the present invention provides an air conditioner, such as Figures 1 to 4 As shown, it includes: a main body 100, the main body 100 is provided with a heat exchange air duct 110 and a fresh air duct 120; a refrigerant heat exchange device 200, the refrigerant heat exchange device 200 is arranged on the main body 100 and is at least partially located in the heat exchange air duct 110; and a heat conducting device 300, the heat conducting device 300 is at least partially located in the fresh air duct 120 and abuts against the refrigerant heat exchange device 200, and the heat conducting device 300 is configured to perform heat exchange with the refrigerant heat exchange device 200.

[0024] In the air conditioner, the heat conducting device 300 is at least partially located in the fresh air duct 120 and abuts against the refrigerant heat exchange device 200. The heat conducting device 300 is configured to perform heat exchange with the refrigerant heat exchange device 200. When the fresh air function is used in winter, the heat generated by the refrigerant heat exchange device 200 is transferred to the heat conducting device 300, so that the temperature of the heat conducting device 300 increases. When the external fresh air is blown into the room through the fresh air duct 120, it exchanges heat with the heat conducting device 300 and its temperature increases. In this way, the fresh air directly blows toward the human body without causing discomfort to the human body. When the fresh air function is used in summer, the cold generated by the refrigerant heat exchange device 200 is transferred to the heat conducting device 300, so that the temperature of the heat conducting device 300 decreases. When the external fresh air is blown into the room through the fresh air duct 120, it exchanges heat with the heat conducting device 300 and its temperature decreases. In this way, the fresh air directly blows toward the human body and improves the human body's blowing feeling.

[0025] Compared with using a thermistor to heat the fresh air or using a heating tube to heat the fresh air, this solution has higher safety and reliability, lower cost, and occupies less space in the fresh air duct 120.

[0026] In some examples, the heat conducting device 300 includes: a heat conducting portion, the heat conducting portion is in contact with the refrigerant heat exchange device 200, and the heat conducting portion is configured to perform heat exchange with the refrigerant heat exchange device 200; and a heat exchange portion 310, the heat exchange portion 310 is located in the fresh air duct 120 and is arranged on the heat conducting portion, and the heat exchange portion 310 performs heat exchange with the heat conducting portion. Among them, the material of the heat exchange portion 310 is set to copper or aluminum with good thermal conductivity, etc., which can achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the scope of protection of this application.

[0027] In some embodiments, Figures 2 to 4As shown, the heat conduction part includes: a heat conduction block 330, which is in contact with the refrigerant heat exchange device 200; and a heat conduction pipe 320, which is connected to the heat conduction block 330, and the heat exchange part 310 is arranged on the heat conduction pipe 320. Among them, the material of the heat conduction block 330 is set to copper or aluminum with good thermal conductivity, and the material of the heat conduction pipe 320 is set to copper or aluminum with good thermal conductivity, which can achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should belong to the protection scope of this application.

[0028] It can be, for example Figure 3 As shown, the heat exchange part 310 is set as a heat exchange wire, and the heat exchange wire is wound on the heat conducting pipe 320. In this solution, the wind resistance formed by the heat exchange part 310 in the fresh air duct 120 is small, but the heat exchange effect between the fresh air and the heat exchange part 310 is slightly poor; or it can be, as Figure 4 As shown, the heat exchange part 310 is configured as a heat exchange plate, which is inserted into the heat pipe 320, and there is a wind gap between adjacent heat exchange plates. In this solution, the heat exchange effect between the fresh air and the heat exchange part 310 is better, but the wind resistance formed by the heat exchange part 310 in the fresh air duct 120 is slightly high.

[0029] It can be that the heat conducting block 330 includes one and the heat conducting pipe 320 includes one; or it can be that Figure 3 and Figure 4 As shown, the heat conductive block 330 includes one, the heat conductive pipe 320 includes a plurality of heat conductive pipes 320 arranged at intervals, and the heat exchange plate is inserted into the plurality of heat conductive pipes 320. In this solution, the plurality of heat conductive pipes 320 generate relatively small wind resistance to fresh air due to the interval arrangement; or it may be that the heat conductive block 330 includes a plurality of heat conductive pipes 320 includes a plurality of heat conductive pipes 320 arranged at intervals, and each heat conductive block 330 is connected to one or more heat conductive pipes 320. In this solution, the plurality of heat conductive pipes 320 generate relatively small wind resistance to fresh air due to the interval arrangement; the above can all achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of the present application.

[0030] In some embodiments, Figure 3 and Figure 4 As shown, the heat conductive block 330 includes one, the heat conductive pipe 320 includes multiple heat conductive pipes 320 arranged at intervals, and the multiple heat conductive pipes 320 and the heat conductive block 330 are cast into one body. This solution has a simple structure, low manufacturing cost, and low wind resistance to fresh air.

[0031] In some embodiments, a heat conductive material (not shown in the figure) is provided at the position where the heat conductive block 330 abuts against the refrigerant heat exchange device 200, and the heat conductive material can increase the contact area between the heat conductive block 330 and the refrigerant heat exchange device 200, so that the heat transfer effect between the heat conductive block 330 and the refrigerant heat exchange device 200 is better. Among them, the heat conductive material is set to thermal conductive silicone grease or solder, etc., which can achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all belong to the protection scope of this application.

[0032] In some examples, such as Figure 1 and Figure 2 As shown, the refrigerant heat exchange device 200 includes: a heat exchanger, a fresh air duct 120 located outside the heat exchange duct 110, the heat exchanger is arranged in the heat exchange duct 110, and the heat conductive block 330 is located between the fresh air duct 120 and the heat exchange duct 110 and abuts against the heat exchanger. Among them, the heat exchanger is set as an indoor heat exchanger, the heat exchange duct 110 is set as an indoor heat exchange duct, and the main body 100 is set as an indoor unit of the air conditioner.

[0033] In some embodiments, Figure 2 As shown, the heat conducting block 330 is provided with a slot 331 , and the copper tube (ie, the U-shaped copper tube 210 ) at one end of the heat exchanger adjacent to the heat conducting block 330 is inserted into the slot 331 , and thermal grease is provided between the copper tube and the inner surface of the slot 331 .

[0034] Among them, Figure 2 As shown, the slot 331 is configured as an arc-shaped slot, and the shape of the arc-shaped slot matches the shape of the U-shaped copper tube 210 , so that the contact area between the heat conducting block 330 and the U-shaped copper tube 210 is larger and the heat transfer effect is better.

[0035] The air conditioner provided in the present application may be a split type air conditioner (such as Figure 1 As shown), it can also be an integrated air conditioner, etc., which can achieve the purpose of this application. Its purpose does not deviate from the design concept of the present invention and will not be repeated here. All should fall within the protection scope of this application.

[0036] To sum up, in the air conditioner provided by the embodiment of the present invention, the heat conducting device is at least partially located in the fresh air duct and abuts against the refrigerant heat exchange device, and the heat conducting device is configured to perform heat exchange with the refrigerant heat exchange device. When the fresh air function is used in winter, the heat generated by the refrigerant heat exchange device is transferred to the heat conducting device, so that the temperature of the heat conducting device increases, and the external fresh air exchanges heat with the heat conducting device and its temperature increases during the process of being blown into the room through the fresh air duct. In this way, the fresh air directly blows toward the human body without causing discomfort to the human body; when the fresh air function is used in summer, the cold generated by the refrigerant heat exchange device is transferred to the heat conducting device, so that the temperature of the heat conducting device decreases. In the process of being blown into the room through the fresh air duct, the external fresh air exchanges heat with the heat conducting device and its temperature decreases. In this way, the fresh air directly blows toward the human body and enhances the human body's blowing feeling.
