[0029] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0030] CN104848516A discloses an air calling laminated pipe sheet and heat exchanger, which comprises a laminated pipe sheet, an inlet assembly K1 and an outlet assembly K2 arranged on the top of the laminated pipe sheet, a flow channel arranged between the inlet assembly K1 and the outlet assembly K2, the flow channel comprising an upper flow channel communication structure K3 arranged on the upper part of the laminated pipe sheet and a lower flow channel communication structure K4 arranged on the lower part of the laminated pipe sheet; the inlet assembly K1, the laminated pipe sheet, the upper flow channel communication structure K3, the lower flow channel communication structure K4 and the outlet assembly K2 form a heat exchange channel. The laminated pipe sheet comprises a plurality of laminated pipe sheets, and a first boss Q1 and a second boss Q2 arranged in rows on the pipe sheet.

[0031] It can improve the heat exchange performance, but the heat dissipation amount of this scheme is limited, the wind resistance is large, the energy loss is large, the wind noise is high, and it is easy to block after long time use and not easy to clean.

[0032] The utility model discloses an embodiment of a tube piece type radiator, which can solve the technical problem of low heat dissipation efficiency in the prior art, thereby reducing energy loss and improving air flow rate.

[0033] The technical solutions of the present application will be described in detail below through specific embodiments:

[0034] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the embodiment of the present application provides a tube piece type radiator, which comprises a heat pipe 100 and two fins 200. The heat pipe 100 is in the shape of a wing, having good aerodynamic performance. The two fins 200 are arranged in parallel, and the fin 200 is provided with a mounting hole 210, the shape of the mounting hole 210 being adapted to the shape of the heat pipe 100, and the heat pipe 100 is mounted in the mounting hole 210.

[0035] The fin 200 comprises a plurality of arc-shaped portions 220 and a plurality of straight portions 230, and the arc-shaped portions 220 and the straight portions 230 are arranged alternately along the length direction of the fin 200. This structure increases the heat exchange area of the fin 200 and improves the heat exchange performance of the fin 200 and air. At the same time, the design of the arc-shaped portion 220 can also guide the air flowing into the radiator, improve the local flow field, and further improve the heat dissipation efficiency.

[0036] The tube piece type radiator disclosed in the embodiment improves the heat pipe 100 of the flat tube straight fin 200 radiator into a wing-shaped tube, reduces the air resistance of the radiator, and at the same time ensures the heat exchange area and the cross-sectional area of the heat flow in the tube. The fin 200 of the flat tube straight fin 200 radiator is improved into a wing-shaped corrugated fin 200, which increases the heat exchange area of the fin 200 and guides the air flowing into the radiator, improving the local flow field. By using the way of guiding the air flow direction, the air flow channel inside the radiator is narrowed, the air flow rate in the flow channel is forced to increase, the air temperature near the high-temperature solid is reduced, and the heat dissipation performance is improved.

[0037] In one embodiment, the heat pipe 100 and the fin 200 are preliminarily fixed by welding or strong adhesion, etc., and then are integrally brazed to ensure the structural strength.

[0038] By welding or strong adhesion, etc., the heat pipe 100 and the fin 200 can be tightly connected together in a local area. This preliminary fixation ensures the relative position stability of the heat pipe 100 and the fin 200 in the subsequent processing process, preventing them from moving relatively during processing or transportation.

[0039] On the basis of the initial fixation, the overall brazing can further enhance the connection strength between the heat pipe 100 and the fin 200. During the brazing process, the filler metal melts and fills the small gap between the heat pipe 100 and the fin 200, forming a metallurgical bond, thereby ensuring the firmness and sealing of the connection.

[0040] In one embodiment, the length of the mounting port 210 is greater than the sum of the lengths of the arc-shaped part 220 and the straight part 230. This allows the mounting port 210 to cover the junction of the arc-shaped part 220 and the straight part 230, ensuring a firm connection between the heat pipe 100 and the fin 200.

[0041] This design increases the contact area between the heat pipe 100 and the fin 200, thereby improving the stability of their connection. During the operation of the radiator, this stable connection can prevent the heat pipe 100 from falling off due to vibration or thermal expansion, ensuring the long-term reliable operation of the radiator.

[0042] The longer mounting port 210 provides more support points for the heat pipe 100, enhancing the structural strength of the radiator. In harsh working environments, such as the vibration and impact often encountered by engineering vehicles, this enhanced structural strength can ensure that the radiator remains intact, prolonging its service life.

[0043] In one embodiment, the starting end of each mounting port 210 is located at the junction of the arc-shaped part 220 and the previous straight part 230.

[0044] Setting the starting end of the mounting port 210 at the junction of the arc-shaped part 220 and the previous straight part 230 ensures that the heat pipe 100 and the fin 200 are in closer and more uniform contact. This design allows heat to be more smoothly transferred from the heat pipe 100 to the fin 200, as the junction is a heat concentration area. By placing the mounting port 210 here, the heat can be more effectively utilized, improving the heat dissipation efficiency.

[0045] In one embodiment, the end of the mounting port 210 extends to the second straight part 230, ensuring that the heat pipe 100 can fully cover the straight part 230 area of the fin 200, which helps to effectively transfer and dissipate heat on the straight part 230. At the same time, the end of the mounting port 210 is spaced apart from the third arc-shaped part 220. This leaves space for heat transfer between the arc-shaped part 220 and the straight part 230, avoiding heat accumulation and optimizing the heat dissipation path.

[0046] The design of the mounting port 210 not only considers the heat dissipation efficiency, but also takes into account the structural stability. The end extending to the second straight part 230 provides additional support points for the heat pipe 100, enhancing the connection strength between the heat pipe 100 and the fin 200. This design helps to resist external vibration and impact, maintaining the overall structural stability of the radiator.

[0047] In one embodiment, the mounting ports 210 are arranged in multiple rows along the width direction of the fin 200, each row including multiple mounting ports 210, and the mounting ports 210 in adjacent rows are staggered.

[0048] The multiple rows of mounting ports 210 provide more support points for the fin 200. This design enhances the bending and torsional strength of the fin 200, so that the heat sink can remain stable under external forces and is not easily deformed or damaged.

[0049] The multiple rows of mounting ports 210 provide more support points for the fin 200. This design enhances the bending and torsional strength of the fin 200, so that the heat sink can remain stable under external forces and is not easily deformed or damaged.

[0050] The multiple rows of mounting ports 210 provide more support points for the fin 200. This design enhances the bending and torsional strength of the fin 200, so that the heat sink can remain stable under external forces and is not easily deformed or damaged.

[0051] The multiple rows of mounting ports 210 provide more support points for the fin 200. This design enhances the bending and torsional strength of the fin 200, so that the heat sink can remain stable under external forces and is not easily deformed or damaged.

[0052] The multiple rows of mounting ports 210 provide more support points for the fin 200. This design enhances the bending and torsional strength of the fin 200, so that the heat sink can remain stable under external forces and is not easily deformed or damaged.

[0053] The multiple rows of mounting ports 210 provide more support points for the fin 200. This design enhances the bending and torsional strength of the fin 200, so that the heat sink can remain stable under external forces and is not easily deformed or damaged.

[0054] The multiple rows of mounting ports 210 provide more support points for the fin 200. This design enhances the bending and torsional strength of the fin 200, so that the heat sink can remain stable under external forces and is not easily deformed or damaged.

[0055] The multiple rows of mounting ports 210 provide more support points for the fin 200. This design enhances the bending and torsional strength of the fin 200, so that the heat sink can remain stable under external forces and is not easily deformed or damaged.

[0056] In one embodiment, the arc portion 220 is semi- wing-shaped, and the leading edge of the arc portion 220 is arranged in the same direction as the leading edge of the heat pipe 100.

[0057] The semi- wing-shaped arc portion 220 design can reduce the air resistance when the air flows through the fin 200, reduce the wind noise, and improve the efficiency of air flow at the same time. This design enables the air to flow more smoothly through the surface of the fin 200, and the heat exchange with the heat pipe 100 is more efficient, thereby improving the heat dissipation performance of the heat sink.

[0058] When the leading edge of the arc portion 220 is in the same direction as the leading edge of the heat pipe 100, the heat pipe 100 can be more directly exposed to the air, reducing the path and obstruction of heat transfer.

[0059] Because the leading edge of the arc portion 220 is in the same direction as the leading edge of the heat pipe 100, the air can more evenly contact the heat pipe 100 when flowing through the fin 200, avoiding the occurrence of local overheating.

[0060] In one embodiment, the included angle of the trailing edge of the arc portion 220 can generally be set between 0 degrees and 180 degrees. However, in some embodiments of the present embodiment, the included angle of the trailing edge of the arc portion 220 can be set between 0 degrees and 30 degrees.

[0061] When the included angle is between 0 degrees and 30 degrees, the air can flow more smoothly when flowing through the arc portion 220, reducing the generation of vortex and turbulence, thereby reducing air resistance and improving the efficiency of air flow. This helps to enhance the heat exchange between the heat sink and the air, and improve the heat dissipation performance.

[0062] A suitable included angle of the trailing edge can reduce the noise generated when the air flows through the fin 200. Too large or too small included angle can cause the air to flow unsmoothly and generate noise. The included angle range of 0 degrees to 30 degrees can better balance the air flow and noise control, so that the heat sink can efficiently dissipate heat while maintaining a low wind noise level.

[0063] In one embodiment, the heat pipe 100 has zero curvature. Straight heat pipes 100 are simpler to manufacture than curved heat pipes 100. They do not need to go through an additional bending process, thereby reducing manufacturing costs and production time. This is particularly important for mass production, as simplifying the manufacturing process can improve production efficiency and reduce unit cost.

[0064] Straight heat pipes 100 are more structurally stable. Curved heat pipes 100 can deform over time or under external forces, while straight heat pipes 100 can better maintain their original shape, thereby improving the overall stability and reliability of the heat sink.

[0065] Of course, setting the heat pipe 100 as a symmetric structure with zero camber is only one embodiment in this embodiment, and in other embodiments, it is also possible to set the heat pipe 100 as an asymmetric structure with a camber greater than zero.

[0066] In certain application scenarios, such as space-limited or linear arrangement of the heat sink design, it is more appropriate to use the heat pipe 100 with zero camber. They can make more efficient use of limited space and provide stable heat dissipation performance.

[0067] In some cases, the curved heat pipe 100 can be more advantageous. For example, when it is necessary to adapt to complex heat sink structures or increase the heat dissipation area, the curved heat pipe 100 can better fit the heat sink surface, thereby improving the heat transfer efficiency. Therefore, when selecting the camber of the heat pipe 100, it is necessary to comprehensively consider the specific application scenario and heat dissipation requirements.

[0068] It should be noted that the straight line connecting the leading edge and the trailing edge of the airfoil is called the chord 110, and its length is called the chord length. The maximum distance between the camber line and the chord 110 is called the camber. The airfoil with zero camber is called a symmetric airfoil, in which the camber line coincides with the chord 110.

[0069] Through the above embodiments, the application has the following beneficial effects or advantages: the tube-fin heat sink disclosed in the application improves the heat dissipation efficiency, structural strength, air flow performance and manufacturing feasibility of the heat sink through optimization of the matching of the heat pipe 100 and the fin 200, the structure of the fin 200, the layout and size of the mounting port 210, the staggered arrangement of the multiple rows of mounting ports 210, the orientation of the leading edge of the arc-shaped portion 220 and the heat pipe 100, the trailing edge angle of the arc-shaped portion 220 and the straight line design of the heat pipe 100. This design balances the performance, reliability and manufacturing cost of the tube-fin heat sink, and is more suitable for various occasions requiring efficient, reliable and low-noise heat dissipation.
