[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Figure 1 An exploded view of one embodiment of an air conditioner 20 according to the present invention is shown. Figure 2 FIG. 1 is a front view of an embodiment of a display assembly 10 according to the present invention. Figure 1 and Figure 2 The display assembly 10 includes a display cover 110 and a heat pipe 120 .

[0036] At least part of the heat pipe 120 is disposed on the inner side of the display cover 110, the top end of the heat pipe 120 is used to connect the heat dissipation fluid, and the bottom end of the heat pipe 120 is located on the outer side of the display cover 110 for the heat dissipation fluid to flow out. The top end of the heat pipe 120 is used to receive the heat dissipation fluid, the heat dissipation fluid flows through the heat pipe 120, and then flows out from the bottom end of the heat pipe 120, and the collected condensed water is used to cool the heat pipe 120, thereby reducing the temperature rise on the surface of the components in the display assembly 10, and solving the problem of poor heat dissipation performance of the display assembly 10 of the air conditioner 20 in the prior art.

[0037] Figure 3 FIG. 2 shows a partially enlarged view of an embodiment of an air conditioner 20 according to the present invention. Figure 3 The display assembly 10 includes a mounting box 130 and a display panel 140 .

[0038] The display panel 140 is located on a side of the installation box 130 close to the display cover 110 , and the heat pipe 120 is located between the display cover 110 and the display panel 140 .

[0039] In the first embodiment, the top end of the heat pipe 120 is located above the installation box 130 .

[0040] In the second embodiment, the bottom end of the heat pipe 120 is located below the installation box 130 .

[0041] In the third embodiment, the top end of the heat pipe 120 is located above the installation box 130 , and the bottom end of the heat pipe 120 is located below the installation box 130 .

[0042] Figure 8 FIG. 1 shows a schematic structural diagram of the air conditioner 20 according to the present invention during cooling. Fig. 9 Shows Figure 8 Enlarged view of part C in the middle. Fig.10 Shows Figure 8 The enlarged view of the part D in the figure. Figure 8 , Fig. 9 and Fig.10 When the air conditioner 20 is in a cooling state, the heat pipe 120 is used to collect condensed water inside the indoor unit of the air conditioner 20. The condensed water flows in the pipe of the heat pipe 120 to cool the heat pipe 120 using the temperature of the condensed water.

[0043] When the air conditioner 20 is in a cooling state, the temperature of the indoor unit is low, and the display screen 250 and the display panel 140 generate a lot of heat, resulting in a high temperature of the display assembly 10. Therefore, condensed water will be generated on the outer surface of the display cover 110 of the display assembly 10. In order to prevent the condensed water from flowing to the display screen 250 assembly and threatening the electrical safety of the display screen 250 assembly, the sealing of the display assembly 10 is very important. In addition, the display screen 250 of the air conditioner 20 will release a lot of heat when it runs for a long time, causing the temperature rise of the components in the display assembly 10 to be too high. If a sealing structure is provided in the display assembly 10, the heat dissipation of the display assembly 10 will be poor, which will damage the performance of the components. Therefore, when the display screen 250 is installed on the indoor unit of the air conditioner 20, the heat dissipation and sealing of the display assembly 10 are particularly important. The display assembly 10 in the above embodiment not only ensures the sealing of the display assembly 10 but also enhances the heat dissipation effect of the display assembly 10.

[0044] See also Fig. 9 A water collecting tank 150 is disposed on the top of the display cover 110 , and the top end of the heat pipe 120 is installed on the top of the display cover 110 and communicates with the water collecting tank 150 , so that the liquid flow in the water collecting tank 150 flows into the heat pipe 120 .

[0045] See also Fig. 9 The display assembly 10 is installed on the panel 210 of the air conditioner 20, and a condensate collecting tank 221 is provided on the evaporator bracket of the air conditioner 20. The water collecting tank 150 is arranged opposite to the drain port 222 of the condensate collecting tank 221 so that the condensate in the condensate collecting tank 221 flows into the heat pipe 120 to absorb the heat in the display assembly 10.

[0046] When the air conditioner 20 is in a cooling state, condensed water may be generated on the evaporator bracket where the evaporator is placed inside the indoor unit, and the condensed water inside the indoor unit may also fall on the evaporator bracket. The condensed water will be stored in the condensed water collecting tank 221 and flow out of the condensed water collecting tank 221 through the drain port 222 opened on the evaporator bracket. The condensed water then falls into the water collecting tank 150 through the through holes on the windshield bracket in turn, and then falls to the upper end of the heat pipe 120, and is discharged to the drain groove 240 on the windshield through the heat pipe 120, and then discharged to the outdoor environment. In this process, since the condensed water with a lower temperature flows in the heat pipe 120, the temperature of the outer surface of the heat pipe 120 is reduced, which can cool the display assembly 10.

[0047] In some embodiments, when the air conditioner 20 is in a cooling state, the heat pipe 120 can be connected to the pipeline of the evaporator, that is, the refrigerant can enter the heat pipe 120 through the pipeline of the evaporator, and the refrigerant can be used to reduce the temperature of the outer surface of the heat pipe 120, which is beneficial to the heat dissipation of the display assembly 10.

[0048] See also Fig. 9 The bottom of the water collecting tank 150 is provided with a first through hole for the top of the heat conducting pipe 120 to pass through. The display assembly 10 also includes a first seal 160. The first seal 160 is sleeved on the top of the heat conducting pipe 120 and is clamped between the heat conducting pipe 120 and the inner wall of the first through hole. The first seal 160 and the first through hole are interference fitted. The inner wall of the first seal 160 is provided with a plurality of protrusions to ensure that the first seal 160 and the heat conducting pipe 120 are easily connected and can effectively prevent condensed water or flying insects from entering the display assembly 10, so as to achieve the sealing of the display assembly 10.

[0049] See also Fig.10 The display cover 110 is provided with a second through hole for the bottom end of the heat pipe 120 to pass through. The display assembly 10 also includes a second seal 170. The second seal 170 is sleeved on the bottom end of the heat pipe 120 and is sandwiched between the heat pipe 120 and the second through hole. There is an interference fit between the second seal 170 and the second through hole. The inner wall of the second seal 170 is provided with a plurality of protrusions to ensure that the second seal 170 and the heat pipe 120 are easily connected and can effectively prevent condensed water or flying insects from entering the display assembly 10, so as to achieve the sealing of the display assembly 10.

[0050] In some embodiments, the material of the first sealing member 160 may be rubber, and the material of the second sealing member 170 may be rubber.

[0051] In some embodiments, the heat pipe 120 is connected to the display cover 110 through the cooperation between the first sealing member 160 and the first through-hole and the cooperation between the second sealing member 170 and the second through-hole.

[0052] In some embodiments, the display cover 110 is connected to the mounting box 130 via fasteners.

[0053] In some embodiments, the heat pipe 120 includes a first pipe segment, a second pipe segment, and a third pipe segment sequentially arranged along the vertical direction.

[0054] In some embodiments, the first pipe section and the third pipe section are straight pipe sections arranged in the vertical direction, and the second pipe section is a curved pipe section. The heat pipe 120 is arranged above the display screen 250 and the display panel 140. The heat pipe 120 with a bend has a larger contact area with the airflow or liquid. The heat pipe 120 can absorb heat more effectively to reduce the temperature rise on the surface of the components in the display assembly 10, and can better dissipate heat for the display assembly 10.

[0055] In addition, the bent heat pipe 120 can ensure that the heat dissipation effect of cold air or condensed water in the heat pipe 120 is optimized.

[0056] The display assembly 10 includes a mounting box 130 and a display panel 140 .

[0057] In the first embodiment, a plurality of heat dissipation holes 131 are provided at intervals on the installation box 130. Eight heat dissipation holes 131 may be provided on the installation box 130 to facilitate better heat dissipation of the display screen 250.

[0058] In the second embodiment, a ventilation grille 111 is provided on the display cover 110 , and the free ends of the ribs of the ventilation grille 111 are tilted downward relative to their fixed ends to prevent condensed water from entering the display assembly 10 and falling on the display panel 140 or the display screen 250 .

[0059] Figure 4 FIG. 2 shows a partially enlarged view of an embodiment of an air conditioner 20 according to the present invention. Figure 4 A ventilation grille 111 is disposed on the display cover 110 . The ventilation grille 111 includes a plurality of ribs arranged parallel to each other. The distance between adjacent baffles may be less than 3 mm to ensure that flying insects do not enter the display assembly 10 .

[0060] In the second embodiment, a plurality of heat dissipation holes 131 are arranged at intervals on the installation box 130, and a ventilation grille 111 is arranged on the display cover 110. The free ends of the ribs of the ventilation grille 111 are arranged to be tilted downward relative to the fixed ends thereof.

[0061] The air conditioner 20 includes a housing and a display assembly 10. The display assembly 10 is disposed on a panel 210 of the housing. The display assembly 10 is the display assembly 10 of the above embodiment.

[0062] In some embodiments, an air inlet is disposed on the top of the housing.

[0063] The top end of the heat pipe 120 of the display assembly 10 is connected to the air inlet, so that when the air conditioner 20 is in the heating mode, the cold air entering the heat pipe 120 through the air inlet absorbs the heat in the display assembly 10 .

[0064] Figure 5 A schematic structural diagram of the air conditioner 20 according to the present invention during heating is shown. Figure 6 Shows Figure 5 Enlarged view of part A in the figure. Figure 7 Shows Figure 5 Enlarged view of part B in the figure. Figure 5 , Figure 6 and Figure 7 When the air conditioner 20 is in a heating state, the heat pipe 120 is cooled by air flow exchange with the outside.

[0065] In some embodiments, when the air conditioner 20 is in the heating state, the air inlet of the air conditioner 20 is located at the top. The cold air in the indoor environment enters the indoor unit, and a part of the air flow can flow into the heat pipe 120 from the drainage hole on the evaporator bracket. The cold air without heat exchange directly enters the heat pipe 120, causing the temperature of the outer surface of the heat pipe 120 to decrease, which can cool the display component.

[0066] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0067] In the present invention, a heat pipe 120 is disposed inside the display cover 110 in the display assembly, and the bottom end of the heat pipe 120 is located outside the display cover. The top end of the heat pipe 120 is used to receive the heat dissipation fluid, which flows through the heat pipe 120 and then flows out from the bottom end of the heat pipe 120. The collected condensed water is used to cool the heat pipe 120, thereby reducing the temperature rise on the surface of the components in the display assembly 10, and solving the problem of poor heat dissipation performance of the display assembly 10 of the air conditioner 20 in the prior art.
