[0035] In the related art, an air conditioner includes an outdoor unit and an indoor unit. A condenser is provided in the outdoor unit, and an evaporator is provided in the indoor unit. A refrigerant cycle is formed by connecting the evaporator and the condenser through a refrigerant pipe. When the air conditioner works, the temperature of the condenser is relatively high. Generally, a cooling fan is provided in the outdoor unit to assist the condenser in dissipating heat. Due to the limited heat dissipation capacity of the cooling fan, the temperature of the condenser is still relatively high during operation, affecting the refrigeration performance of the air conditioner.

[0036] Referring to Figures 1 to 5 , a radiator assembly according to an embodiment of the first aspect of the present invention includes a cooling pipe assembly 200, a plurality of heat exchange pipes 100, and a plurality of heat exchange fins (not shown in the figure). The plurality of heat exchange pipes 100 are arranged at intervals in an array, and the plurality of heat exchange fins are arranged at intervals along the length direction of the heat exchange pipes 100. Each heat exchange pipe 100 passes through the plurality of heat exchange fins, and the cooling pipe assembly 200 passes through the plurality of heat exchange fins and is located at the upper end of the heat exchange fins. The cooling pipe assembly 200 is provided with a plurality of water outlet holes 201, and the water outlet holes 201 face the lower end of the heat exchange fins. The plurality of water outlet holes 201 are arranged side by side at intervals along the axial direction of the heat exchange pipes 100, and at least one water outlet hole 201 is located between adjacent heat exchange fins. In this way, by providing the cooling pipe assembly 200, cooling water can enter the interior of the radiator assembly through the cooling pipe assembly 200, and the cooling water can flow to between adjacent heat exchange fins through the corresponding water outlet holes 201 to cool the heat exchange fins at different positions, which can reduce the working temperature of the radiator assembly and thus improve the refrigeration performance of the air conditioner.

[0037] For example, each water outlet hole 201 is located between adjacent heat exchange fins. When cooling the radiator assembly, the cooling water enters the interior of the radiator assembly through the cooling pipe assembly 200. The cooling water flows through the corresponding water outlet hole 201 to between adjacent heat exchange fins, enabling the cooling water to contact the surfaces of the adjacent heat exchange fins, so as to cool the heat exchange fins at different positions, reduce the operating temperature of the radiator assembly, and thus improve the refrigeration performance of the air conditioner.

[0038] It should be noted that two or three water outlet holes 201 may also be located between adjacent heat exchange fins, and there is no limitation here.

[0039] It should be pointed out that the aperture of the water outlet hole 201 is D, and the minimum distance between adjacent heat exchange fins is L, satisfying: D ≤ L / 2. On the one hand, it can reduce the flow resistance of air between adjacent heat exchange fins. On the other hand, it can ensure the water output of the cooling water to effectively cool the heat exchange fins and improve the refrigeration performance of the air conditioner.

[0040] In some embodiments of the present invention, the cooling pipe assembly 200 includes a connector 210 and a cooling pipe body 220 connected to the connector 210. A plurality of water outlet holes 201 are provided on the cooling pipe body 220. One end of the connector 210 is provided with a water inlet joint 211 communicating with the cooling pipe body 220. The water inlet joint 211 is used to communicate with a water pump, and the output end of the water pump is communicated with the water inlet joint 211 through a water pipe, which can facilitate the water pump to supply water to the cooling pipe body 220.

[0041] For example, the cooling pipe body 220 is of a tubular structure. By providing a water inlet joint 211 at one end of the connector 210, the water inlet joint 211 can be inserted and matched with the water pipe connected to the output end of the water pump, which can facilitate the assembly of the radiator assembly and thus facilitate the water pump to supply water to the cooling pipe body 220.

[0042] In some embodiments of the present invention, a clamping structure is provided between the connector 210 and the cooling pipe body 220, which can facilitate the installation of the cooling pipe body 220 and thus improve the assembly efficiency of the cooling pipe assembly 200.

[0043] As another implementation manner, the connector 210 can also be fixedly connected to the cooling pipe body 220 by welding, where the welding methods include but are not limited to resistance welding, laser welding, or ultrasonic welding, etc.

[0044] In some embodiments of the present invention, the clamping structure includes a clamping groove 212 provided on the connector 210. A part of the cooling pipe body 220 is accommodated in the clamping groove 212 and is clamped with the side wall of the clamping groove 212, which can facilitate the installation of the cooling pipe body 220 and thus improve the assembly efficiency of the cooling pipe assembly 200.

[0045] For example, along the recessed direction of the card slot 212, the width of the card slot 212 first increases and then decreases. Along the direction perpendicular to the axial direction of the cooling pipe body 220, the shape of the cross-section of the cooling pipe body 220 matches the shape of the cross-section of the card slot 212. A part of the cooling pipe body 220 is accommodated in the card slot 212 and is clamped with the side wall of the card slot 212, which can facilitate the installation of the cooling pipe body 220, thereby improving the assembly efficiency of the cooling pipe assembly 200.

[0046] It should be noted that the cooling pipe body 220 can also be completely accommodated in the card slot 212, and there is no limitation here.

[0047] As another implementation manner, the clamping structure can also be a structure in which a first hook and a second hook cooperate. One of the first hook and the second hook is provided on the connecting member 210, and the other is provided on the cooling pipe body 220. The hook portion of the first hook is clamped with the hook portion of the second hook, which can also facilitate the installation of the cooling pipe body 220, and there is no limitation here.

[0048] In some embodiments of the present invention, the radiator further includes a first mounting plate 310 and a second mounting plate 320. The first mounting plate 310 abuts against the side of the first heat exchange fin away from the last heat exchange fin, and the second mounting plate 320 abuts against the side of the last heat exchange fin away from the first heat exchange fin. The cooling pipe body 220 passes through the first mounting plate 310 and the second mounting plate 320, and the water inlet joint 211 is located on the side of the first mounting plate 310 away from the second mounting plate 320, which can facilitate the installation and fixation of the heat exchange fins.

[0049] For example, the first mounting plate 310 and the second mounting plate 320 are arranged opposite to each other along the axial direction of the heat exchange tube 100. A plurality of heat exchange fins are located between the first mounting plate 310 and the second mounting plate 320. The first heat exchange fin among the plurality of heat exchange fins is fixedly connected to the first mounting plate 310, and the last heat exchange fin is fixedly connected to the second mounting plate 320, which can facilitate the installation and fixation of the heat exchange fins.

[0050] In some embodiments of the present invention, a fixed joint 213 is provided at one end of the connecting member 210 away from the water inlet joint 211. The fixed joint 213 is provided with an annular groove 214. The annular groove 214 is arranged around the axis of the fixed joint 213. The side wall of the annular groove 214 is clamped with the second mounting plate 320. There is no need to fix the connecting member 210 by bolting, which can improve the installation efficiency of the connecting member 210.

[0051] In some embodiments of the present invention, the cooling pipe assembly 200 further includes a positioning member 230. The positioning member 230 is sleeved on the water inlet joint 211. The positioning member 230 is provided with a positioning portion 231. In the axial direction of the water outlet hole 201, the positioning portion 231 is located on the side of the positioning member 230 away from the water outlet hole 201, and can position the orientation of the water outlet hole 201 in the radiator assembly to ensure that the water outlet hole 201 can spray water downward.

[0052] For example, the positioning portion 231 is a positioning hole. When installing the cooling pipe assembly 200, rotate the connecting member 210 so that the positioning portion 231 faces upward. At this time, the water outlet hole 201 faces downward, and then pass a fastener through the positioning hole to fixedly connect the positioning member 230 to the first mounting plate 310, so as to position the orientation of the water outlet hole 201 in the radiator assembly to ensure that the water outlet hole 201 can spray water downward.

[0053] As another implementation manner, the positioning portion 231 can also be a positioning protrusion, and it is only necessary to correspondingly provide a through hole on the first mounting plate 310 that matches the positioning protrusion, which will not be limited herein.

[0054] In some embodiments of the present invention, the positioning member 230 and the connecting member 210 are of an integral structure, which can reduce the number of molds, so as to reduce the production and manufacturing cost of the molds, thereby reducing the production and manufacturing cost of the radiator assembly.

[0055] For example, the positioning member 230 and the connecting member 210 can be integrally formed by die-casting, which can reduce the number of molds, so as to reduce the production and manufacturing cost of the molds, thereby reducing the production and manufacturing cost of the radiator assembly.

[0056] As another implementation manner, the positioning member 230 and the connecting member 210 can also be connected by welding, which will not be elaborated herein.

[0057] In some embodiments of the present invention, the outer diameter of the heat exchange pipe 100 matches the maximum width of the connecting member 210 along the radial direction of the heat exchange pipe 100, so that the cooling pipe assembly 200 can replace the heat exchange pipe 100 of the existing condenser. On the one hand, the cooling pipe assembly 200 can replace or assist the heat exchange pipe 100 in heat dissipation in a water spraying manner, improving the refrigeration performance of the air conditioner. On the other hand, the number of heat exchange pipes 100 can be reduced, thereby reducing the manufacturing cost of the radiator assembly.

[0058] Refer to Figure 1 、 Figure 2, The air conditioner according to the second aspect embodiment of the present invention includes the radiator assembly of the first aspect embodiment of the present invention. By providing the cooling pipe assembly 200, cooling water can enter the interior of the radiator assembly through the cooling pipe assembly 200, and the cooling water can flow between adjacent heat exchange fins through the corresponding water outlet holes 201 to cool the heat exchange fins at different positions, which can reduce the working temperature of the radiator assembly and thus improve the refrigeration performance of the air conditioner.

[0059] For example, each water outlet hole 201 is located between adjacent heat exchange fins. When cooling the radiator assembly, the cooling water enters the interior of the radiator assembly through the cooling pipe assembly 200, and the cooling water flows between adjacent heat exchange fins through the corresponding water outlet holes 201, enabling the cooling water to contact the surfaces of adjacent heat exchange fins to cool the heat exchange fins at different positions, which can reduce the working temperature of the radiator assembly and thus improve the refrigeration performance of the air conditioner.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
