[0034] In related technologies, the bending process of flat tubes requires more precise control of their external dimensions, which not only increases the complexity of the manufacturing process, but also raises the requirements for material and assembly precision.

[0035] The following is for reference. Figures 1-7 A heat exchanger 1 according to an embodiment of the present utility model is described.

[0036] like Figures 1-4As shown, the heat exchanger 1 according to this utility model is used in a clothing processing device. The heat exchanger 1 includes a flat tube assembly, which has multiple flat tubes 11. Each flat tube 11 has a medium flow channel and fins 112. The medium flow channel refers to the space inside the flat tube 11, used to accommodate and guide the flow of the heat exchange medium. The fins 112 are structures attached to the outside of the flat tubes 11 to increase the heat exchange area, thereby improving the heat exchange efficiency. The flat tubes 11 are constructed to extend in a first direction, with multiple flat tubes 11 stacked in a second direction. A gap is formed between adjacent flat tubes 11 to allow airflow, enabling the airflow to pass evenly through the gap between adjacent flat tubes 11, thus ensuring sufficient contact with the flat tubes 11 and fins 112, achieving efficient heat exchange.

[0037] The heat exchanger 1 also includes a manifold assembly, which is connected to the flat tubes 11 and includes an inlet manifold 13 for guiding the heat exchange medium into the medium flow channel and an outlet manifold 14 for guiding the heat exchange medium out of the medium flow channel. The inlet manifold 13 is used to distribute the heat exchange medium into the medium flow channels of each flat tube 11, while the outlet manifold 14 is used to collect the medium after heat exchange and discharge it from the heat exchanger 1.

[0038] The fin 112 is constructed as a comb-shaped fin and is inserted into the gap between two adjacent flat tubes 11. The comb-shaped fin refers to a fin form with multiple parallel rows of tooth-like structures. The two adjacent tooth-like structures can be inserted and matched with the flat tubes 11, which is easy to assemble.

[0039] Therefore, according to the heat exchanger 1 of this utility model, by constructing the fins 112 as comb-shaped fins, the assembly process between the fins 112 and the flat tube 11 is simplified, and the assembly efficiency can be improved.

[0040] According to some embodiments of this utility model, such as Figures 1-3 As shown, the flat tube assembly is constructed as multiple rows interconnected in a third direction. After the heat exchange medium flows and exchanges heat in one flat tube 11, it can flow out and enter another adjacent row of flat tubes 11 for further flow and heat exchange. This allows the heat exchange medium to form a complex flow path between the multiple rows of flat tubes 11, increasing the flow length and heat exchange area of ​​the heat exchange medium in the overall structure, thereby effectively improving the heat exchange efficiency.

[0041] According to some embodiments of this utility model, such as Figures 1-3As shown, the manifold assembly includes manifolds 12 extending upwards in a third direction. Manifolds 12 are disposed at the ends of flat tubes 11 and are configured as multiple manifolds corresponding to multiple rows of flat tubes 11. A flow channel is formed inside the manifold 12 for collecting and distributing the heat exchange medium. By placing the manifolds 12 at the ends of the flat tubes 11, the heat exchange medium can enter and exit each row of flat tubes 11. At least two adjacent manifolds 12 in a third-direction upward direction are connected to each other to connect adjacent rows of flat tubes 11, allowing the heat exchange medium to flow from one row of flat tubes 11 into an adjacent row of flat tubes 11. Therefore, the heat exchange medium can form a complex flow path between the multiple rows of flat tubes 11, increasing the flow length and heat exchange area of ​​the heat exchange medium, thereby significantly improving the heat exchange efficiency.

[0042] By setting up a manifold 12, which connects at least two adjacent rows of flat tubes 11, the heat exchange medium can flow between multiple rows of flat tubes 11. This eliminates the need for bending the flat tubes, simplifies the manufacturing process, and reduces the requirements for precise control of dimensions. It not only reduces the potential accumulation of errors during manufacturing but also relaxes the stringent requirements for material specifications and assembly accuracy. Therefore, production costs are effectively reduced, and production efficiency is significantly improved.

[0043] According to some embodiments of this utility model, such as Figure 1 As shown, at least two adjacent rows of flat tubes 11 have connecting ports 111 on the same side of their first direction, which communicate with the medium flow channel. The connecting ports 111 serve as the connection between the medium flow channel of the flat tubes 11 and the manifold 12, allowing the heat exchange medium to flow between the flat tubes 11 and the manifold 12. The outer periphery of the manifold 12 communicates with the connecting ports 111 of the corresponding row of flat tubes 11, simplifying the structure and improving assembly convenience. After the heat exchange medium flows out of the connecting port 111 of one row of flat tubes 11, it can directly enter the manifold 12 and then be distributed to the adjacent row of flat tubes 11 through the manifold 12, forming a continuous flow path.

[0044] According to some embodiments of this utility model, the connecting port 111 is constructed as an elongated elliptical hole, and the manifold 12 is formed with an elongated elliptical hole adapted to the connecting port 111. By constructing the mating openings of the connecting port 111 and the manifold 12 with the connecting port 111 as elongated elliptical holes, the flow requirements of the heat exchange medium can be better accommodated, while increasing the contact area between the connecting port 111 and the manifold 12, thereby improving the stability and sealing of the connection. The flow of the heat exchange medium between the manifold 12 and the connecting port 111 is smoother, reducing flow resistance and further improving the heat exchange efficiency of the heat exchanger 1.

[0045] According to some embodiments of the present invention, the manifold 12 is constructed as a closed end and an open end at its two ends in the third direction, and the open ends of at least two adjacent manifolds 12 in the third direction are connected to each other to connect two adjacent rows of flat tubes 11.

[0046] The closed end of the manifold 12 is sealed, preventing the heat exchange medium from entering or exiting through it. This ensures the heat exchange medium flows only along a predetermined path between the manifold 12 and the flat tubes 11, preventing leakage or unnecessary flow branching. In contrast to the closed end, the open end of the manifold 12 is open, allowing the heat exchange medium to enter and exit the collection channels within the manifold 12. At least two adjacent manifolds 12 have interconnected open ends, allowing the heat exchange medium to flow from one manifold 12 to another, thus achieving communication between adjacent rows of flat tubes 11.

[0047] The heat exchanger 1 also includes a plug 15, which is disposed between the closed ends of two adjacent manifolds 12 in the first direction to seal the connection between the two adjacent manifolds 12 in the first direction.

[0048] By setting the plug 15, two adjacent manifolds 12 in the first direction are sealed together, thereby ensuring that the flow path of the heat exchange medium between the manifolds 12 is effectively closed and preventing heat exchange medium leakage. The plug 15 also simplifies the assembly and maintenance process of the heat exchanger 1. By setting the plug 15 between two adjacent manifolds 12, a sealed connection can be quickly achieved, reducing installation difficulty and maintenance costs.

[0049] According to some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the comb-shaped fins include a main body 1121 and comb teeth 1122. Multiple comb teeth 1122 are arranged at intervals on one side of the main body 1121 in the width direction and extend away from the main body 1121. A through groove is formed between adjacent comb teeth 1122 to facilitate insertion and engagement with the flat tube 11. The comb-shaped fins can be quickly and accurately inserted and engaged with the flat tube 11 through the through groove, simplifying the assembly process and improving assembly efficiency. Inserting the fins 112 into the heat exchanger 2 via insertion facilitates easy assembly and disassembly.

[0050] According to some embodiments of this utility model, such as Figure 5 As shown, the comb-tooth portion 1122 has a protrusion 1122a formed on at least one side in the thickness direction. The protrusion 1122a can effectively block the lint entering the heat exchanger 1 and prevent it from adhering to the surface of the heat exchanger 1, thereby avoiding a decrease in heat exchange efficiency.

[0051] According to some embodiments of this utility model, such as Figure 6As shown, the comb-tooth portion 1122 has through-holes 1122b formed in the thickness direction. After being guided by the through-holes 1122b on the comb-tooth portion 1122, the airflow forms a more complex flow path in the heat exchanger 1, which increases the contact area and contact time between the airflow and the wall of the heat exchanger 1, allowing the airflow to exchange heat more fully with the medium inside the heat exchanger 1, thereby improving the overall heat exchange efficiency of the heat exchanger 1.

[0052] According to some embodiments of this utility model, such as Figure 7 As shown, at least one flat tube 11 is constructed as a serpentine tube. A serpentine tube refers to a structure in which the flat tube 11 is curved in space, which allows the heat exchange medium to form a longer flow path within the flat tube 11, thereby increasing the contact time and contact area between the heat exchange medium and the flat tube 11 and the fins 112, and further improving the heat exchange efficiency.

[0053] According to some embodiments of this utility model, such as Figure 1 As shown, the liquid inlet manifold 13 has a steam inlet and a steam outlet that are connected to each other, and the steam outlet of the liquid inlet manifold 13 is connected to the open end of at least one manifold 12; the liquid outlet manifold 14 has a liquid outlet and a liquid inlet that are connected to each other, and the liquid inlet of the liquid outlet manifold 14 is connected to the open end of at least another manifold 12.

[0054] The inlet manifold 13 is used to introduce the heat exchange medium into the heat exchanger 1. The inlet manifold 13 has a steam inlet and a steam outlet, which are interconnected, so that the heat exchange medium can flow in from the steam inlet and then flow through the interior of the inlet manifold 13 to the steam outlet. By connecting the steam outlet of the inlet manifold 13 to the open end of at least one manifold 12, the heat exchange medium is allowed to flow from the inlet manifold 13 into the manifold 12, and then be distributed and flow between the manifold 12 and the flat tube 11 connected thereto.

[0055] The outlet manifold 14 is used to discharge the heat exchange medium after heat exchange from the heat exchanger 1. The outlet manifold 14 has an outlet and an inlet, which are connected to each other. By connecting the inlet of the outlet manifold 14 to the open end of at least one other manifold 12, the heat exchange medium is allowed to flow from the manifold 12 into the outlet manifold 14 and then out of the heat exchanger 1.

[0056] According to some embodiments of this utility model, the steam outlets on the liquid inlet manifold 13 are configured as multiple outlets spaced apart in the second direction. Each layer of flat tubes 11 is connected to a corresponding manifold 12 connected to a steam outlet of the liquid inlet manifold 13, so that the heat exchange medium can be evenly distributed into each layer of flat tubes 11. The heat exchange medium flows from the multiple steam outlets of the liquid inlet manifold 13 into the corresponding manifolds 12, and then into each layer of flat tubes 11, ensuring the uniform distribution and efficient flow of the heat exchange medium in each layer.

[0057] The spaced steam outlets optimize the distribution efficiency of the heat exchange medium. Each layer of flat tube 11 is connected to an independent steam outlet through a manifold 12, allowing the heat exchange medium to flow independently in each layer, avoiding mutual interference between different layers, thereby further improving the overall performance of the heat exchanger 1.

[0058] By spacing the steam outlets in the second direction, the layout of the multi-layer flat tube 11 can be better adapted, ensuring that the heat exchange medium can enter each layer of flat tube 11 quickly and evenly.

[0059] According to some embodiments of this utility model, the liquid inlets on the liquid outlet manifold 14 are configured as multiple inlets spaced apart in the second direction. Each layer of flat tubes 11 is connected to another manifold 12, which is correspondingly connected to one liquid inlet of the liquid outlet manifold 14, so that the heat exchange medium can be uniformly collected and discharged from each layer of flat tubes 11. After heat exchange, the heat exchange medium flows from each layer of flat tubes 11 into the corresponding manifold 12, and then flows into the liquid outlet manifold 14 through the multiple liquid inlets and is discharged, ensuring efficient discharge of the heat exchange medium.

[0060] The spaced-outlet liquid inlets optimize the collection efficiency of the heat exchange medium. Each layer of flat tubes 11 is connected to an independent liquid outlet through a manifold 12, allowing the heat exchange medium to flow out independently in each layer of flat tubes 11, further improving the overall performance of the heat exchanger 1.

[0061] By arranging the liquid inlets at intervals in the second direction, the layout of the multi-layer flat tubes 11 can be better adapted, ensuring that the heat exchange medium can flow out of each layer of flat tubes 11 quickly and evenly, shortening the flow path of the heat exchange medium, reducing flow resistance, and improving heat exchange efficiency.
