Description

Technical Field

[0001] The utility model belongs to the technical field of parallel flow aluminum flat tubes, and in particular relates to a special-shaped parallel flow heat exchange aluminum flat tube for a high heat exchange air conditioner. Background Art

[0002] Microchannel aluminum flat tube, also known as "parallel flow aluminum flat tube", is a thin-walled porous flat tubular material made of refined aluminum rods, through hot extrusion and surface zinc spraying for corrosion protection. It is mainly used as a pipeline component for carrying new environmentally friendly refrigerants in air-conditioning systems. A channel for the circulation of refrigerant is set in the microchannel aluminum flat tube, so that the refrigerant can circulate in the air-conditioning system or heat exchange device, thereby playing a role in heat exchange.

[0003] At present, there are significant defects in the design of aluminum flat tubes in the prior art, the most prominent of which is the failure to fully explore the potential of the internal surface area of ​​the pipe to optimize heat transfer. This leads to unsatisfactory heat exchange efficiency and fails to reach the ideal state. In addition, these aluminum flat tubes generally adopt straight channels or overly simple flow channel designs, which not only make the fluid face greater resistance when flowing in the pipe, but also increase unnecessary energy losses, thereby reducing the operating efficiency of the entire system. What is more troublesome is that the existing aluminum flat tubes are often formed in one piece, which makes their structure relatively fixed and lacks sufficient flexibility. This design limitation makes it difficult for aluminum flat tubes to adapt to various small or complex installation spaces, greatly limiting their application potential in specific application scenarios. This not only affects the compactness and space utilization of the equipment, but may also lead to the inability to find a suitable heat exchange solution in some cases.

[0004] Therefore, it is very necessary to invent a special-shaped parallel flow heat exchange aluminum flat tube for high heat exchange air conditioning. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a special-shaped parallel flow heat exchange aluminum flat tube for a high heat exchange air conditioner, comprising a hollow aluminum flat frame, a heat exchange special-shaped tube, a clamping fixing head, anti-slip grooves and notches. The heat exchange special-shaped tube and the clamping fixing head are installed inside the hollow aluminum flat frame, the heat exchange special-shaped tube and the clamping fixing head are connected to each other, and the clamping fixing head is provided with anti-slip grooves; four notches are opened on the hollow aluminum flat frame.

[0006] Preferably, the hollow aluminum flat frame has a rounded square hollow cavity, and both ends of the hollow aluminum flat frame are respectively provided with "U"-shaped notches, two notches form a group, and there are two groups in total, and the two notches in each group are arranged on the same vertical line.

[0007] Preferably, the cross-section of the heat exchange shaped tube is a rounded square surface, and the heat exchange shaped tube is composed of a shaped portion and a joint portion. The shaped portion of the heat exchange shaped tube is a wave-shaped structure, and its two joint portions are the two ends of the heat exchange shaped tube, and the shaped portion is the middle part of the heat exchange shaped tube. There are gaps between the plurality of heat exchange shaped tubes to allow heat exchange.

[0008] Preferably, the snap-fit ​​fixing head is a rounded square structure, and the two snap-fit ​​fixing heads are respectively installed in the hollow cavity of the hollow aluminum flat frame with transition fit, and the snap-fit ​​fixing head is provided with an interface groove for transition fit with the joint part of the heat exchange special-shaped tube; the anti-slip pattern of the snap-fit ​​fixing head is located on the inner side of the notch opened in the hollow aluminum flat frame, and the anti-slip pattern is a wavy raised anti-slip structure.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model abandons the limitations of one-piece molding and straight channel design in traditional technologies, and innovatively adopts modular and wave channel design, which gives it significant advantages of reducing fluid resistance, efficient heat transfer, and compact flexibility. Specifically, the design of the wave-shaped gas channel not only significantly increases the surface area inside the pipeline, but also provides more contact points for heat transfer, allowing heat to be transferred more quickly and efficiently inside the pipeline, thereby greatly improving the heat exchange efficiency of the entire system. At the same time, this design can also make the flow of fluid in the pipeline smoother, effectively guide the flow of fluid, significantly reduce the resistance of the fluid in the pipeline, and thus improve the fluid dynamics performance of the entire system.

[0011] In addition, the unique flat shape of the aluminum flat tube enables it to better fit into a small space, significantly improving the compactness of the equipment. At the same time, the independent heat exchange shaped tube design gives the pipeline greater flexibility in layout and installation, and can easily cope with various complex installation requirements.

[0019] As attached Figure 1 To Attachment Figure 3 As shown:

[0020] The utility model provides a special-shaped parallel flow heat exchange aluminum flat tube for high heat exchange air conditioner, comprising a hollow aluminum flat frame 1, a heat exchange special-shaped tube 2, a clamping fixing head 3, anti-skid patterns 4 and a notch 5. The heat exchange special-shaped tube 2 and the clamping fixing head 3 are installed inside the hollow aluminum flat frame 1, the heat exchange special-shaped tube 2 and the clamping fixing head 3 are connected to each other, and the clamping fixing head 3 is provided with anti-skid patterns 4; four notches 5 are provided on the hollow aluminum flat frame 1. The parallel flow heat exchange aluminum flat tube abandons the limitations of one-piece molding and straight channel design in traditional technology, and innovatively adopts modularization and wave channel design, thereby giving it significant advantages of reducing fluid resistance, efficient heat transfer and compact flexibility.

[0021] Embodiment 1:

[0022] Specifically, the hollow aluminum flat frame 1 has a rounded square hollow cavity, and the two ends of the hollow aluminum flat frame 1 are respectively provided with "U"-shaped notches 5, two notches 5 form a group, and two groups are provided in total, and the two notches 5 in each group are arranged on the same vertical line, and the notches 5 can be used for convenient disassembly of the clamping fixing head 3. This design not only improves the layout and installation process of the equipment, but also can easily cope with various complex installation requirements.

[0023] Specifically, the cross section of the heat exchange shaped tube 2 is a rounded square surface. Compared with the traditional circular or square cross section, this design can balance the fluid resistance and heat exchange efficiency to a certain extent. The rounded design reduces the turbulence and eddy current of the fluid at the corners of the pipe, reducing the fluid resistance; while the square design increases the surface area of ​​the pipe and improves the heat exchange efficiency. The heat exchange shaped tube 2 is composed of a shaped part and a joint part. The shaped part of the heat exchange shaped tube 2 is a wave-shaped structure. This wave-shaped structure not only further increases the surface area of ​​the pipe and provides more contact points for heat transfer, but also can guide the fluid to form a more complex flow pattern inside the pipe, further enhancing the heat exchange effect. In addition, the wave-shaped structure also has a certain elasticity, which can absorb and relieve the stress caused by temperature changes in the pipe to a certain extent, and improve the service life of the pipe. Its two joints are the two ends of the heat exchange shaped tube 2, and the shaped part is the middle part of the heat exchange shaped tube 2. There is a gap between many of the heat exchange shaped tubes 2 to allow heat exchange.

[0024] Specifically, the snap-fit ​​fixing head 3 is a rounded square structure, and the two snap-fit ​​fixing heads 3 are respectively installed in the hollow cavity of the hollow aluminum flat frame 1 with transition fit. The snap-fit ​​fixing head 3 is provided with an interface groove for transition fit with the joint part of the heat exchange shaped tube 2; the anti-slip pattern 4 of the snap-fit ​​fixing head 3 is located on the inner side of the notch 5 provided in the hollow aluminum flat frame 1, and the anti-slip pattern 4 is a wavy raised anti-slip structure, which installs the hollow aluminum flat frame 1, the heat exchange shaped tube 2 and the snap-fit ​​fixing head 3 together through transition fit. This modular design not only improves the convenience of assembly, but also makes it easier to repair and replace parts. The design of the snap-fit ​​fixing head 3 enables the heat exchange shaped tube 2 to be firmly fixed inside the hollow aluminum flat frame 1, improving the structural stability of the entire system.

[0025] Embodiment 2:

[0026] First, through modular design, the hollow aluminum flat frame 1 and one of the clamping fixing heads 3 are pre-assembled, and then the interface grooves provided in the assembled clamping fixing head 3 are used to install a plurality of heat exchange shaped tubes 2 in the hollow cavity of the hollow aluminum flat frame 1, and then another clamping fixing head 3 is installed with the heat exchange shaped tube 2 and the hollow aluminum flat frame 1. During the installation process, the interface grooves of the clamping fixing head 3 and the joints of the heat exchange shaped tubes 2 are transitionally matched to ensure that the heat exchange shaped tubes 2 are firmly fixed inside the aluminum flat frame.

[0027] When working, the refrigerant or coolant of the air conditioning system flows through the heat exchange shaped tube 2. Since the heat exchange shaped tube 2 adopts a wavy structure design, its surface area is significantly increased, providing more contact points for heat transfer. At the same time, the wavy structure can also guide the fluid to form a more complex flow pattern inside the pipeline, enhancing the heat exchange effect between the fluid and the pipeline wall. In addition, the wavy structure also has a certain elasticity, which can absorb and relieve the stress caused by temperature changes, and extend the service life of the pipeline. In the process of the fluid flowing through the heat exchange shaped tube 2, due to the design of the rounded square cross-section, the turbulence and eddy current of the fluid at the corner of the pipeline are effectively reduced, thereby reducing the fluid resistance and improving the fluid dynamics performance. This design not only ensures efficient heat transfer, but also reduces the fluid resistance, achieving a balance between heat exchange efficiency and fluid dynamics performance. In addition, the notch 5 on the hollow aluminum flat frame 1 is not only used to install and fix the clamping fixing head 3, but also provides a convenient disassembly and maintenance channel when necessary. This design makes the entire system more flexible and maintainable, and can adapt to various complex installation requirements.

[0028] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
