[0036] In related technologies, an air conditioner includes an outdoor unit and an indoor unit. The outdoor unit contains a condenser, and the indoor unit contains an evaporator. The evaporator and condenser are connected by refrigerant pipes to form a refrigerant circulation. When the air conditioner is operating, the condenser temperature is relatively high. A cooling fan is typically installed in the outdoor unit to assist in cooling the condenser. However, due to the limited cooling capacity of the cooling fan, the condenser temperature remains high during operation, affecting the air conditioner's cooling performance.

[0037] Reference Figures 1 to 5 According to a first aspect embodiment of the present invention, a radiator assembly 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 in an array at intervals, and the plurality of heat exchange fins are arranged at intervals along the length of the heat exchange pipes 100. Each heat exchange pipe 100 passes through the plurality of heat exchange fins. 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. 1. Facing the lower end of the heat exchange fins, multiple water outlets 201 are arranged side by side at intervals along the axial direction of the heat exchange tube 100, and at least one water outlet 201 is located between adjacent heat exchange fins. In this way, by setting the cooling tube assembly 200, cooling water can enter the interior of the radiator assembly through the cooling tube assembly 200, and the cooling water can flow to the space between adjacent heat exchange fins through the corresponding water outlets 201 to cool the heat exchange fins located at different positions, thereby reducing the operating temperature of the radiator assembly and improving the cooling performance of the air conditioner.

[0038] For example, each water outlet 201 is located between adjacent heat exchange fins. When cooling the radiator assembly, cooling water enters the interior of the radiator assembly through the cooling pipe assembly 200. The cooling water flows through the corresponding water outlet 201 to the space between adjacent heat exchange fins, so that the cooling water can contact the surface of the adjacent heat exchange fins to cool the heat exchange fins located in different positions. This can reduce the operating temperature of the radiator assembly and thus improve the cooling performance of the air conditioner.

[0039] It should be noted that two or three water outlets 201 may also be located between adjacent heat exchange fins, and there is no restriction on this.

[0040] It should be noted that the diameter of the water outlet 201 is D, and the minimum spacing between adjacent heat exchange fins is L, satisfying: D≤L / 2. On the one hand, this can reduce the air flow resistance between adjacent heat exchange fins, and on the other hand, it can ensure the output of cooling water to effectively cool the heat exchange fins and improve the cooling performance of the air conditioner.

[0041] In some embodiments of this utility model, 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 connector 211 that communicates with the cooling pipe body 220. The water inlet connector 211 is used to communicate with a water pump. The output end of the water pump is connected to the water inlet connector 211 through a water pipe, which can facilitate the water pump to supply water to the cooling pipe body 220.

[0042] For example, the cooling pipe body 220 has a tubular structure. By setting a water inlet connector 211 at one end of the connector 210, the water inlet connector 211 can be plugged into the water pipe connected to the output end of the water pump, which facilitates the assembly of the radiator assembly and makes it convenient for the water pump to supply water to the cooling pipe body 220.

[0043] In some embodiments of this utility model, a snap-fit ​​structure is provided between the connector 210 and the cooling pipe body 220, which facilitates the installation of the cooling pipe body 220 and thereby improves the assembly efficiency of the cooling pipe assembly 200.

[0044] As another implementation, the connector 210 can also be fixedly connected to the cooling pipe body 220 by welding, wherein the welding method includes, but is not limited to, resistance welding, laser welding or ultrasonic welding.

[0045] In some embodiments of this utility model, the snap-fit ​​structure includes a snap-fit ​​groove 212 provided in the connector 210, and a portion of the cooling pipe body 220 is accommodated in the snap-fit ​​groove 212 and snap-fitted with the side wall of the snap-fit ​​groove 212, which facilitates the installation of the cooling pipe body 220 and thereby improves the assembly efficiency of the cooling pipe assembly 200.

[0046] For example, along the recessed direction of the slot 212, the width of the 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 slot 212. Part of the cooling pipe body 220 is accommodated in the slot 212 and engages with the side wall of the slot 212, which facilitates the installation of the cooling pipe body 220 and improves the assembly efficiency of the cooling pipe assembly 200.

[0047] It should be noted that the cooling pipe body 220 can also be completely accommodated in the slot 212, and there is no restriction on this.

[0048] As another implementation, the snap-fit ​​structure can also be a structure in which a first snap hook and a second snap hook cooperate. One of the first snap hook and the second snap hook is provided on the connector 210, and the other is provided on the cooling pipe body 220. The hook part of the first snap hook engages with the hook part of the second snap hook, which can also facilitate the installation of the cooling pipe body 220. No limitation is made here.

[0049] In some embodiments of this utility model, 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. The water inlet connector 211 is located on the side of the first mounting plate 310 away from the second mounting plate 320, which facilitates the installation and fixing of the heat exchange fins.

[0050] For example, the first mounting plate 310 and the second mounting plate 320 are arranged opposite each other along the axial direction of the heat exchange tube 100, and 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 facilitates the installation and fixing of the heat exchange fins.

[0051] In some embodiments of this utility model, the end of the connector 210 away from the water inlet connector 211 is provided with a fixed connector 213. The fixed connector 213 is provided with an annular groove 214. The annular groove 214 is arranged around the axis of the fixed connector 213. The side wall of the annular groove 214 is engaged with the second mounting plate 320. The connector 210 does not need to be fixed by bolts, which can improve the installation efficiency of the connector 210.

[0052] In some embodiments of this utility model, the cooling pipe assembly 200 further includes a positioning member 230, which is sleeved on the water inlet connector 211. The positioning member 230 is provided with a positioning part 231. On the axial direction of the water outlet 201, the positioning part 231 is located on the side of the positioning member 230 away from the water outlet 201, which can position the orientation of the water outlet 201 in the radiator assembly to ensure that the water outlet 201 can spray water downwards.

[0053] For example, the positioning part 231 is a positioning hole. When installing the cooling pipe assembly 200, the connecting piece 210 is rotated so that the positioning part 231 faces upward. At this time, the water outlet 201 faces downward. Then, the fastener is inserted into the positioning hole so that the positioning piece 230 is fixedly connected to the first mounting plate 310. This can position the orientation of the water outlet 201 in the radiator assembly to ensure that the water outlet 201 can spray water downward.

[0054] As another implementation, the positioning part 231 can also be a positioning protrusion. A through hole matching the positioning protrusion can be provided on the first mounting plate 310. There is no limitation here.

[0055] In some embodiments of this utility model, the positioning member 230 and the connecting member 210 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the radiator assembly.

[0056] For example, the positioning component 230 and the connecting component 210 can be integrally formed by die casting, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the radiator assembly.

[0057] As another implementation, the positioning member 230 and the connecting member 210 can also be connected by welding, which will not be described in detail here.

[0058] In some embodiments of this utility model, the outer diameter of the heat exchange tube 100 is matched with the maximum radial width of the connector 210 along the heat exchange tube 100, so that the cooling tube assembly 200 can replace the heat exchange tube 100 of the existing condenser. On the one hand, the cooling tube assembly 200 can replace or assist the heat exchange tube 100 in heat dissipation by water spraying, thereby improving the cooling performance of the air conditioner. On the other hand, it can reduce the number of heat exchange tubes 100, thereby reducing the manufacturing cost of the radiator assembly.

[0059] Reference Figure 1 , Figure 2According to the second aspect of the present invention, the air conditioner includes the radiator assembly of the first aspect 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 through the corresponding water outlet 201 to the space between adjacent heat exchange fins to cool the heat exchange fins located at different positions, thereby reducing the operating temperature of the radiator assembly and improving the cooling performance of the air conditioner.

[0060] For example, each water outlet 201 is located between adjacent heat exchange fins. When cooling the radiator assembly, cooling water enters the interior of the radiator assembly through the cooling pipe assembly 200. The cooling water flows through the corresponding water outlet 201 to the space between adjacent heat exchange fins, so that the cooling water can contact the surface of the adjacent heat exchange fins to cool the heat exchange fins located in different positions. This can reduce the operating temperature of the radiator assembly and thus improve the cooling performance of the air conditioner.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
