Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, and specifically relates to a novel finned heat exchanger. Background Technology

[0002] Traditional heat exchangers often use finned tube structures to improve heat exchange efficiency, but existing designs have the following problems: 1. Conventional heat exchanger frames mostly use flat cover plates, which have limited connection strength and are easily deformed by thermal stress. 2. The connection method between the liquid collector and the finned tube is simple, resulting in a restricted flow path for the hot and cold media and low local heat exchange efficiency. 3. The height of the liquid collector is not properly matched with the frame, occupying too much external installation space and hindering condensate drainage. 4. The surface of the cover plate is smooth, requiring additional reinforcement when connecting to external pipes or fasteners, increasing complexity. Utility Model Content

[0003] The main objective of this invention is to provide a novel finned heat exchanger that achieves efficient heat exchange and improves stability through optimized frame structure and symmetrical layout of liquid collection pipes.

[0004] To achieve the above objectives, this utility model provides a novel finned heat exchanger, which includes a heat exchanger frame composed of upper and lower cover plates and left and right cover plates. A metal finned tube is disposed inside the heat exchanger frame, and a plurality of annular fins are disposed on the metal finned tube. Liquid collecting pipes are symmetrically arranged on both sides of the heat exchanger frame, and the two ends of the metal finned tube are connected to the liquid collecting pipes.

[0005] This utility model provides a novel finned heat exchanger. The frame structure enhances overall rigidity and reduces the risk of thermal expansion and deformation. The symmetrical liquid collection tube design enables bidirectional and uniform fluid distribution, improving heat exchange uniformity. The annular fins increase the heat dissipation area, enhance the turbulence effect, and improve heat exchange efficiency, thereby achieving high-efficiency heat exchange and improving stability.

[0006] In one possible implementation, the lower ends of the liquid collecting pipes on both sides are respectively provided with liquid outlet pipes and liquid inlet pipes. Hot and cold media enter and exit from the bottom, utilizing gravity for natural convection to reduce pumping energy consumption.

[0007] In one possible implementation, the top of the liquid collecting pipe is flush with the top of the heat exchanger frame. This design ensures a seamless connection between the top of the liquid collecting pipe and the frame, preventing gas accumulation and the formation of "airlock," thus guaranteeing the continuity of media flow.

[0008] In one possible implementation, the bottom end of the liquid collection pipe is higher than the bottom end of the heat exchanger frame. This design reduces the positional limitations when connecting the liquid collection pipe to external pipelines and is adaptable to various installation scenarios.

[0009] In one possible implementation, the outer surfaces of the upper and lower cover plates, as well as the left and right cover plates, are all configured as grooved surfaces. The grooved structure increases the surface area of ​​the cover plates, aids in heat dissipation, and simultaneously reduces the overall weight, saving processing materials.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0014] See attached diagram. Figure 1 , Figure 1 This is a schematic diagram of a novel finned heat exchanger structure provided by this utility model, as shown below. Figure 1 As shown, the present invention provides a novel finned heat exchanger comprising a heat exchanger frame 1 composed of upper and lower cover plates and left and right cover plates. A metal finned tube 2 is disposed within the heat exchanger frame, and a plurality of annular fins 3 are disposed on the metal finned tube 2. Liquid collecting pipes 4 are symmetrically disposed on both sides of the heat exchanger frame 1, and both ends of the metal finned tube 2 are connected to the liquid collecting pipes 4.

[0015] This utility model provides a novel finned heat exchanger. The frame structure enhances overall rigidity and reduces the risk of thermal expansion and deformation. The symmetrical liquid collection tube 4 design enables bidirectional and uniform fluid distribution, improving heat exchange uniformity. The annular fins 3 increase the heat dissipation area, enhance the turbulence effect, and improve heat exchange efficiency, thereby achieving high-efficiency heat exchange and improving stability.

[0016] In one possible implementation, the lower ends of the two liquid collection pipes 4 are respectively provided with liquid outlet pipes / liquid inlet pipes 5. Hot and cold media enter and exit from the bottom, utilizing gravity for natural convection to reduce pumping energy consumption.

[0017] In one possible implementation, the top end of the liquid collecting pipe 4 is flush with the top end of the heat exchanger frame 1. This design ensures a seamless connection between the top of the liquid collecting pipe 4 and the frame, preventing gas accumulation and the formation of "air blockages," thus guaranteeing the continuity of medium flow.

[0018] In one possible implementation, the bottom end of the liquid collection pipe 4 is higher than the bottom end of the heat exchanger frame 1. This design reduces the positional limitations when the liquid collection pipe 4 is connected to external pipelines, and is adaptable to various installation scenarios.
