[0035] First Embodiment

[0036] Please refer to the reference. Figures 1 to 3 This utility model embodiment provides a heat exchanger 10 for heat exchange. It can effectively increase the contact area with the coolant, improve heat dissipation efficiency, enhance heat dissipation effect, and meet the user's heat dissipation needs.

[0037] The heat exchanger 10 includes fins 100, a first substrate 200, and a second substrate 300. The first substrate 200 and the second substrate 300 are connected and together form a heat exchange channel for the flow of coolant to achieve the heat exchange function. Specifically, the fins 100 are installed in the heat exchange channel. During the flow of coolant in the heat exchange channel, the coolant passes through the fins 100. The fins 100 are used to guide the flow of coolant, so that the coolant forms turbulence during the flow process, thereby improving the heat exchange performance of the heat exchanger 10.

[0038] The fin 100 includes multiple transverse folds 110 and multiple longitudinal folds 120. The fin 100 is folded in a meandering manner, with the multiple transverse folds 110 and multiple longitudinal folds 120 alternately arranged along its width direction. The transverse folds 110 and longitudinal folds 120 are arranged at a first angle, and the multiple longitudinal folds 120 are spaced apart. In this embodiment, the multiple transverse folds 110 and multiple longitudinal folds 120 are integrally formed to improve the connection strength. Specifically, at least some of the transverse folds 110 and / or at least some of the longitudinal folds 120 have perforated grooves 111 for coolant flow. The perforated grooves 111 have baffles 112 extending from the sidewalls of the perforated grooves 111. The baffles 112 are inclined to the transverse folds 110 and located between two adjacent longitudinal folds 120. The baffles 112 are used to guide a portion of the coolant to interfere with the flow direction of that portion of the coolant. In this way, the horizontal fold 110 and vertical fold 120 set at the first angle, as well as the hollow groove 111 and baffle 112 set on the horizontal fold 110 and / or vertical fold 120, can turbulentize the coolant flowing through the fins 100, so that the coolant forms turbulence during the flow process, thereby effectively increasing the contact area with the coolant, improving heat dissipation efficiency, enhancing heat dissipation effect, and meeting the user's heat dissipation needs.

[0039] In this embodiment, the first angle is 90 degrees, that is, the horizontal fold 110 is perpendicular to the vertical fold 120, and multiple vertical fold 120s are arranged in parallel. The hollowed-out groove 111 and the baffle 112 are only provided on the horizontal fold 110. However, it is not limited to this. In other embodiments, the first angle can be an obtuse angle or an acute angle. In this case, the horizontal fold 110 and two adjacent vertical fold 120 form an isosceles trapezoid; the hollowed-out groove 111 and the baffle 112 can be provided only on the vertical fold 120, or simultaneously on both the horizontal fold 110 and the vertical fold 120.

[0040] Preferably, the perforated groove 111 is polygonal. The perforated groove 111 has a first sidewall 1111 and a second sidewall 1112 opposite to each other. Both the first sidewall 1111 and the second sidewall 1112 are parallel to the longitudinal fold 120. A baffle 112 is disposed on the first sidewall 1111 and / or the second sidewall 1112 (the baffle 112 can be disposed on the first sidewall 1111, the second sidewall 1112, or both). The baffle 112 extends from one longitudinal fold 120 to an adjacent longitudinal fold 120. Coolant can pass between the first sidewall 1111 and the second sidewall 1112 and flow onto the baffle 112, which guides the coolant to create turbulence.

[0041] In this embodiment, the hollow groove 111 is rectangular, but it is not limited to this. In other embodiments, the hollow groove 111 can also be triangular, square, rhomboid, trapezoidal, etc. The shape of the hollow groove 111 is not specifically limited.

[0042] Furthermore, there are multiple hollow slots 111 and multiple baffles 112. The multiple hollow slots 111 are arranged sequentially at intervals along the length direction of the transverse fold 110, and each baffle 112 is disposed on the first sidewall 1111 or the second sidewall 1112 of a hollow slot 111. The multiple hollow slots 111 work together to increase the flow rate of coolant through the fins 100 and improve heat exchange efficiency; the multiple baffles 112 work together to improve the turbulence effect on the coolant, ensure turbulent flow, and thus enhance the heat exchange effect.

[0043] In this embodiment, a baffle plate 112 is disposed on the first side wall 1111 of a hollow groove 111, and an adjacent baffle plate 112 is disposed on the second side wall 1112 of an adjacent hollow groove 111. That is, the extension directions of two adjacent baffle plates 112 are staggered to further improve the baffle effect, improve the heat exchange efficiency, and enhance the heat exchange effect.

[0044] It should be noted that a second angle is formed between the baffle 112 and the transverse fold 110, with the second angle ranging from 30 degrees to 60 degrees. A reasonable second angle can improve the guiding effect on the coolant, increase the flow rate of the coolant, and thus improve the heat exchange efficiency. In this embodiment, the second angle is 45 degrees, and the extension directions of two adjacent baffles 112 are perpendicular to each other, but it is not limited to this. In other embodiments, the second angle can be 30 degrees or 60 degrees, and the size of the second angle is not specifically limited.

[0045] The plurality of horizontal folds 110 include a plurality of first horizontal folds 113 and a plurality of second horizontal folds 114. The plurality of first horizontal folds 113 and the plurality of second horizontal folds 114 are arranged alternately in sequence. The plurality of first horizontal folds 113 are all located on a first plane, and the plurality of second horizontal folds 114 are all located on a second plane. The first plane and the second plane are arranged parallel to each other. In this embodiment, the width of the first horizontal fold 113 is equal to the width of the second horizontal fold 114. Both the first horizontal fold 113 and the second horizontal fold 114 are provided with a plurality of hollowed-out grooves 111 and a plurality of baffles 112. The baffles 112 on the first horizontal fold 113 and the corresponding baffles 112 on the second horizontal fold 114 extend in opposite directions and are arranged parallel to each other.

[0046] In this embodiment, multiple first horizontal folds 113 are located on the first plane, but this is not the only embodiment. In other embodiments, some first horizontal folds 113 are located on the first plane, and another part of the first horizontal folds 113 are located on the third plane. The extension directions of the baffles 112 on the two parts of the first horizontal folds 113 are the same or intersecting. The third plane is set parallel to the first plane and is located between the first plane and the second plane. That is, some first horizontal folds 113 are higher than the other part of the first horizontal folds 113, so as to further improve the heat dissipation efficiency.

[0047] The fin 100 provided in this embodiment of the invention comprises a plurality of transverse folds 110 and a plurality of longitudinal folds 120 arranged alternately along its width direction. The transverse folds 110 and longitudinal folds 120 are arranged at a first angle, and the plurality of longitudinal folds 120 are spaced apart. At least some of the transverse folds 110 and / or at least some of the longitudinal folds 120 have hollowed-out grooves 111. The sidewalls of the hollowed-out grooves 111 are provided with baffles 112, which are inclined to the transverse folds 110 and located between two adjacent longitudinal folds 120. Compared with the prior art, the fin 100 provided in this invention, due to the use of a plurality of transverse folds 110 and a plurality of longitudinal folds 120 arranged alternately, as well as hollowed-out grooves 111 and baffles 112 provided on the transverse folds 110 and / or longitudinal folds 120, can effectively increase the contact area with the coolant, improve heat dissipation efficiency, enhance heat dissipation effect, and meet the user's heat dissipation needs. This results in high heat exchange efficiency and good heat exchange effect for heat exchanger 10.

[0048] Second Embodiment

[0049] Please refer to Figure 4 This utility model embodiment provides a fin 100. Compared with the first embodiment, the difference in this embodiment lies in the different structure of the baffle 112.

[0050] In this embodiment, a welding section 1121 extends from the free end of the baffle 112. The welding section 1121 is arranged parallel to the transverse fold 110. The welding section 1121 is used to weld and fix to the first substrate 200 or the second substrate 300 to fix the relative position of the fin 100 with the first substrate 200 and the second substrate 300, thereby ensuring the heat dissipation effect of the fin 100. In addition, the welding section 1121, as the folded edge structure of the baffle 112, can also improve the strength of the baffle 112, prevent it from bending or breaking, and improve reliability.

There are multiple first baffle holes 1122, which are spaced apart along the extension direction of the baffles 112. The first baffle holes 1122 are used for the flow of coolant to enhance the baffle effect, thereby ensuring the turbulent flow effect of the coolant, improving the heat exchange efficiency, and enhancing the heat exchange effect.

[0055] In this embodiment, the longitudinal fold 120 is provided with a plurality of second turbulence holes 121, which are spaced apart along the length of the longitudinal fold 120.

[0058] Please refer to Figure 6 This utility model embodiment provides a fin 100. Compared with the second embodiment, the difference in this embodiment is that the position of the baffle 112 is different.

[0059] In this embodiment, on a horizontal fold 110, multiple baffles 112 are correspondingly disposed on the first sidewalls 1111 of multiple hollow grooves 111; or, multiple baffles 112 are correspondingly disposed on the second sidewalls 1112 of multiple hollow grooves 111. Specifically, on a first horizontal fold 113, multiple baffles 112 are correspondingly disposed on the first sidewalls 1111 of multiple hollow grooves 111; on an adjacent second horizontal fold 114, multiple baffles 112 are correspondingly disposed on the second sidewalls 1112 of multiple hollow grooves 111; all baffles 112 are arranged in parallel at intervals to enhance the flow guiding effect, increase the flow rate of the coolant, and thus improve the heat exchange efficiency.
