Description

Technical Field

[0001] This utility model relates to the field of air conditioning evaporator technology, specifically to an air-circulating air conditioning evaporator. Background Art

[0002] With social development and the continuous improvement of people's living standards, air conditioners have become indispensable electrical appliances in people's lives. For typical indoor units, the evaporator is a crucial refrigerant circulation component installed inside. A search of existing technology (publication number: CN221005268U) reveals "an evaporator assembly, an indoor air conditioning unit, and an air conditioner. The evaporator assembly includes an upper evaporator, an upper fan, a lower evaporator, and a lower fan. The upper evaporator is a cooling evaporator. The upper fan is located inside the upper evaporator. The lower evaporator is a heating evaporator, positioned below the upper evaporator. The lower fan is located inside the lower evaporator. As the lower evaporator is a heating evaporator, the hot air output by the lower fan rises to the surface after entering the room. Therefore, in dehumidification mode, the cold air emitted by the upper evaporator and the hot air emitted by the lower evaporator can mix to balance the indoor temperature, greatly improving the user experience."

[0003] While existing air conditioner evaporators achieve basic air circulation and cooling effects, they still have some shortcomings: Existing air conditioner indoor unit evaporators reduce the temperature of the surrounding air, then use an internal blower to disperse the cold air around the evaporator, achieving indoor cooling. Evaporators generally consist of circulating copper tubes, end caps, and external heat-conducting fins. However, existing copper tubes are typically laid flat and embedded between the end caps, limiting the area in contact with air and resulting in poor cooling performance. Secondly, the fins on the outside of the copper tubes in existing evaporators are fixedly connected and cannot be disassembled. Although filters are installed on the outside of the fins, prolonged use still leads to dust contamination, and the fins themselves are not easily disassembled for cleaning. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, an air-circulating air conditioner evaporator is provided to solve the problems of poor cooling effect caused by the limited copper tube area of ​​existing air conditioner indoor unit evaporators, and the difficulty in disassembling and cleaning the fin components due to long-term dust contamination.

[0005] To achieve the above objectives, an air-circulating air conditioner evaporator is provided, comprising: an end cap, a copper tube assembly, and a fin assembly. The end cap is connected to both ends of the copper tube assembly, and the fin assembly covers the outside of the copper tube assembly. The copper tube assembly includes a main circuit copper tube, and a first arc-shaped tube, a straight tube, and a second arc-shaped tube are connected between adjacent main circuit copper tubes. The fin assembly includes a connecting rod, and an inner clamping plate is connected to the inner side of the connecting rod. A clamping groove is provided on the inner end of the inner clamping plate, and an outer fin plate is connected to the outer side of the connecting rod. Both ends of the connecting rod are provided with adsorption ends, and the adsorption ends are slidably inserted into the insertion grooves opened on the inner side wall of the end cap.

[0006] Furthermore, the end cap is designed as a C-shaped structure, and the bent ends on both sides of the main circuit copper pipe pass through the end cap and are placed on the outside of the end cap.

[0007] Furthermore, the refrigerant inlet and outlet of the main circuit copper pipe are located on the same side of the end cap, and both the inlet and outlet are located on the outside of the end cap.

[0008] Furthermore, the first arc-shaped tube, the straight tube, and the second arc-shaped tube are located in the same plane, and the first arc-shaped tube and the second arc-shaped tube are symmetrically arranged about the straight tube. At the same time, the first arc-shaped tube, the straight tube, and the second arc-shaped tube are all connected to the adjacent main circuit copper tube.

[0009] Furthermore, the insertion slot is configured as an outer opening slot, and the inner slot wall is provided with a magnet block, and the adsorption end is configured as a magnet block that is attracted to the magnet block with opposite polarity.

[0010] Furthermore, the inner clamping plate is clamped between the tube bodies of the main circuit copper tubes, while the first arc-shaped tube, the straight tube, and the second arc-shaped tube are clamped in the clamping slot.

[0011] Furthermore, when the connecting rod is connected to the end cap, the outer fin is placed between the two end caps, and the outer fin covers the outside of the copper tube assembly along the shape of the end cap.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The main circuit copper pipes included in the copper pipe assembly enable the circulation of low-temperature refrigerant after connection. At the same time, the gaps between the main circuit copper pipes are filled through the first arc-shaped pipe, the straight pipe and the second arc-shaped pipe. Then, through contact with the fin assembly, the internal low-temperature expansion area exchanges heat with the surrounding hot air. Finally, the cold air is blown out by the blower inside the indoor unit to achieve a good cooling effect.

[0014] 2. The connecting rod and adsorption end included in the fin assembly make it easy to remove individual fins from the slots opened inside the end cover from the outside. This allows the fins to be disassembled and cleaned individually after long-term use when they become contaminated. After cleaning, the fins are engaged in the gaps of the copper tube through the slots of the inner clamping plate, achieving direct contact with the copper tube. Then, low-temperature diffusion is achieved through the outer fin plate, thus realizing the effect of easy disassembly and cleaning of the fin components. Attached Figure Description

[0022] Reference Figures 1 to 6 As shown, this utility model provides an air-circulating air conditioner evaporator, including: an end cap 1, a copper tube assembly 2, and a fin assembly 3. The end cap 1 is connected to both ends of the copper tube assembly 2, and the fin assembly 3 covers the outside of the copper tube assembly 2. The copper tube assembly 2 includes a main circuit copper tube 21, and a first arc-shaped tube 22, a straight tube 23, and a second arc-shaped tube 24 are connected between adjacent main circuit copper tubes 21. The fin assembly 3 includes a connecting rod 31, and an inner clamping plate 32 is connected to the inner side of the connecting rod 31. A clamping groove 33 is opened at the inner end of the inner clamping plate 32. At the same time, an outer fin plate 35 is connected to the outside of the connecting rod 31. The two ends of the connecting rod 31 are provided with adsorption ends 34, and the adsorption ends 34 are slidably inserted into the insertion groove 11 opened in the inner wall of the end cap 1.

[0023] In this embodiment, the end cap 1, the copper tube assembly 2, and the fin assembly 3 constitute the main structure of the air-circulating air conditioner evaporator involved in this application.

[0024] The end cap 1 is fixed to the inner wall of the air conditioner indoor unit casing, and an air conditioner filter is provided on the outer side of the fin assembly 3.

[0025] Specifically, the inclination direction of the upper and lower ends of the first arc-shaped tube 22, the straight tube 23, and the second arc-shaped tube 24 between adjacent main circuit copper tubes 21 is biased towards the direction of the refrigerant flowing in the copper tube.

[0026] Specifically, the fin assembly 3 can be installed on one side of the copper tube assembly 2 or on both sides of the copper tube assembly 2. In this case, only two insertion slots 11 need to be opened.

[0027] like Figures 1 to 4 As shown, the end cap 1 is designed with a C-shaped structure, and the bent ends on both sides of the main circuit copper pipe 21 pass through the end cap 1 and are placed on the outside of the end cap 1. The refrigerant inlet and outlet ends of the main circuit copper pipe 21 are located on the same side of the end cap 1, and both the inlet and outlet ends are located on the outside of the end cap 1. The first arc-shaped pipe 22, the straight pipe 23 and the second arc-shaped pipe 24 are in the same plane, and the first arc-shaped pipe 22 and the second arc-shaped pipe 24 are symmetrically arranged about the straight pipe 23. At the same time, the first arc-shaped pipe 22, the straight pipe 23 and the second arc-shaped pipe 24 are all connected to the adjacent main circuit copper pipe 21.

[0028] As a preferred implementation, by setting the first arc-shaped pipe 22, the straight pipe 23 and the second arc-shaped pipe 24, the contact area between the refrigerant flowing through the pipe and the outside air is increased, thereby increasing the cooling effect on the surrounding air.

[0029] like Figure 5 and Figure 6 As shown, the insertion slot 11 is an externally open slot, and the inner side of the slot wall is provided with a magnet. The adsorption end 34 is a magnet that attracts the magnet with opposite polarity. The inner clamping plate 32 is clamped between the tube bodies of the main circuit copper tube 21. At the same time, the first arc-shaped tube 22, the straight tube 23 and the second arc-shaped tube 24 are clamped in the clamping slot 33. When the connecting rod 31 is connected to the end cap 1, the outer fin plate 35 is placed between the two end caps 1, and the outer fin plate 35 covers the outside of the copper tube assembly 2 along the shape of the end cap 1.

[0030] As a preferred implementation, the magnetic connection effect of the insertion slot 11 and the adsorption end 34 facilitates the disassembly of the fin assembly 3. At the same time, by setting the slot 33, the inner card plate 32 can be directly contacted with the outer wall of the copper tube, and the inner card plate 32, the outer fin plate 35 and the connecting rod 31 are all made of heat-conducting material.

[0031] In use, the main circuit copper pipes included in the copper pipe assembly enable the circulation of low-temperature refrigerant after connection. Simultaneously, the first arc-shaped pipe, straight pipe, and second arc-shaped pipe fill the gaps between the main circuit copper pipes. Through contact with the fin assembly, the internal low-temperature area expands, exchanging heat with the surrounding hot air. The cool air is then blown out by the blower inside the indoor unit, achieving a good cooling effect. The connecting rods and adsorption ends included in the fin assembly facilitate the removal of individual fins from the slots inside the end cover. This allows for individual fin removal and cleaning after prolonged use if the fins become contaminated. After cleaning, the inner plate engages with the gaps in the copper pipes through its slots, achieving direct contact with the copper pipes. The low-temperature diffusion is then achieved through the outer fin plate, thus facilitating the disassembly and cleaning of the fin components.

[0032] The air-circulating air conditioner evaporator of this invention can effectively solve the problems mentioned in the background technology. It increases the heat exchange area of ​​the evaporator and facilitates the disassembly and cleaning of the fins based on the existing air-circulating air conditioner evaporator technology.
