In heat exchange equipment technical field, tube-fin heat exchanger includes a plurality of interval setting fins and a plurality of heat exchange tube that wears to locate the fin in proper order, lets in the refrigerant in the heat exchange tube, and the heat exchange air current can flow and take place heat exchange with the fin along the fin surface. In order to improve the heat exchange performance of the tube-fin heat exchanger, the fins are generally made into a corrugated shape to increase the heat exchange area of the fins, and the common corrugated fins are sine corrugated fins, so that the heat exchange performance of the tube-fin heat exchanger can be improved by adopting the sine corrugated fins, but the resistance of the fins to the heat exchange airflow is increased, and the circulation efficiency of the heat exchange airflow is low and the energy consumption is high.
Referring to fig. 1-2, in order to solve the problem that the resistance of a sinusoidal corrugated fin to the heat exchange airflow is increased, resulting in low circulation efficiency and high energy consumption of the heat exchange airflow, the present utility model provides a corrugated fin 100, and in particular, the corrugated fin 100 includes corrugated segments 110 and first horizontal connecting segments 140, wherein a plurality of corrugated segments 110 are arranged at intervals along a first preset direction, adjacent corrugated segments 110 are smoothly connected through the first horizontal connecting segments 140, a plane in which the first horizontal connecting segments 140 are located is set as a reference plane, the corrugated segments 110 located at one side of the reference plane are defined as peak segments 120, the corrugated segments 110 located at the other side of the reference plane are defined as valley segments 130, and the maximum distance from the peak segments 120 to the reference plane is greater than the maximum distance from the valley segments 130 to the reference plane.
It should be noted that, the "first preset direction" refers to a direction from an air inlet end to an air outlet end of the corrugated fin.
Since the plurality of corrugated segments 110 are spaced apart along the first predetermined direction, the heat exchange air flow can flow over the fin surfaces in the first predetermined direction and heat exchange with the fins under the guiding action of the corrugated segments 110. Further, compared with the sinusoidal corrugated fin 100, the corrugated fin 100 provided by the utility model reduces the disturbance effect of the trough sections 130 on the heat exchange airflow by setting the maximum distance from the crest sections 120 to the reference surface to be larger than the maximum distance from the trough sections 130 to the reference surface, thereby reducing the flow shear stress of the heat exchange airflow when the heat exchange airflow flows through the trough sections 130. The flow shear stress of the fluid is a main factor causing flow resistance, and thus, such arrangement is advantageous in reducing resistance of the corrugated fin 100 to the heat exchange gas flow, thereby being advantageous in improving the flow efficiency of the heat exchange gas flow and reducing energy consumption. And, by providing the adjacent corrugated segments 110 to be smoothly connected through the first horizontal connecting segment 140, the structural strength of the corrugated fin 100 is advantageously improved.
Further, in an embodiment, the first horizontal connecting section 140 and the corrugated section 110 are integrally formed, and the forming manner may be stamping forming or casting forming.
In one embodiment, as shown in fig. 2-5, the cross-sectional centerline b of the corrugated segments forms a partial y=ksinx/x functional image, with the maximum spacing of the plurality of corrugated segments 110 from the reference surface in the first predetermined direction tending to decrease.
The "cross-sectional center line b of the corrugated segment" refers to a curve having the same shape as the cross-sectional contour line of the corrugated segment 110.
By setting the cross-section center line b of the corrugated section to form a function image of the part y=ksinx/x, the cross-section center line b of the corrugated section corresponds to a specific function formula, so that the processing difficulty of the corrugated fin 100 is reduced. Because the heat exchange air flow can enter the two sides of the corrugated fin 100 along the first preset direction, the maximum distance from the corrugated sections 110 to the reference surface is in a decreasing trend along the first preset direction, that is, the maximum distance from the corrugated sections 110 to the reference surface is larger at the air inlet end, so that the disturbance effect of the corrugated fin 100 on the heat exchange air flow at the air inlet end can be increased, the heat exchange of the heat exchange air flow and the corrugated fin 100 is facilitated, and the maximum distance from the corrugated sections 110 to the reference surface is smaller at the air outlet end, so that the disturbance effect of the corrugated fin 100 on the heat exchange air flow at the air outlet end can be reduced, and the heat exchange air flow subjected to the heat exchange is facilitated to flow out of the tubular fin type heat exchanger from the air outlet end.
However, in other embodiments, the cross-sectional center line of the peak segment 120 and the cross-sectional center line of the trough segment 130 may have a parabolic shape or a circular arc shape, respectively.
Further, in an embodiment, as shown in fig. 5, the k values corresponding to the cross-sectional centerlines b of the plurality of corrugated segments are equal.
In this manner, the cross-sectional centerlines b of the plurality of bellows segments correspond to different portions of the same y=ksinx/x functional image, thereby facilitating calculation of the spacing of each bellows segment 110 from the reference plane according to the y=ksinx/x formula.
In another embodiment, as shown in fig. 4, k values corresponding to the cross-sectional center lines b of the plurality of corrugated segments may be unequal.
In one embodiment, 0.3.ltoreq.k.ltoreq.0.5.
In this manner, the maximum spacing of the crest segments 120 and the trough segments 130 can be reduced, i.e., the amplitude of the corrugated fin 100 can be reduced, thereby facilitating a reduction in the difficulty of processing the corrugated fin 100. In order to improve the heat exchange performance of the tube-fin heat exchanger, the spacing between adjacent corrugated fins 100 is generally set smaller, so that the tube-fin heat exchanger can mount more corrugated fins 100, and therefore, the amplitude of the corrugated fins 100 is reduced, which is beneficial to adapting the spacing between adjacent corrugated fins 100.
In one embodiment, as shown in fig. 4, each corrugated segment 110 includes a peak segment 120 and two trough segments 130, the two trough segments 130 are located on two sides of the peak segment 120, and the corrugated segments 110 are disposed in mirror symmetry about the centerline of the peak segment 120.
The functional image of y=ksinx/x is symmetrical about the y-axis, and the amplitude of the functional image is maximum at x=0. Thus, by providing each corrugated segment 110 comprising a peak segment 120 and two trough segments 130, the two trough segments 130 are located on either side of the peak segment 120, respectively, and the corrugated segments 110 are mirror symmetric about the centerline of the peak segment 120 such that the cross-sectional centerline b of the corrugated segment corresponds to the portion of the y=ksinx/x function image that is symmetric about the y-axis. In this manner, the resistance of the corrugated fin 100 to the flow of the heat exchange gas is advantageously further reduced.
However, in other embodiments, each corrugated segment 110 may include multiple peak segments 120 and multiple valley segments 130, and the entire corrugated segment 110 may be disposed in mirror symmetry about the centerline of the peak segment 120 with the largest peak. Where peak refers to the maximum separation of the peak segment 120 from the reference plane.
In one embodiment, n corrugated segments and n-1 first horizontal connecting segments connecting adjacent corrugated segments are defined to form a corrugated set, the plurality of corrugated sets are connected end to end along a first predetermined direction, and in each corrugated set, n waves are arranged along the first predetermined directionThe cross-sectional center lines b of the segments correspond to y=k, respectively 1 sinx/x functional image, y=k 2 sinx/x functional image … y=k n-1 sinx/x functional image and y=k n sinx/x.
In this way, the disturbance effect of the corrugated fin 100 on the heat exchange flow is enhanced, so that the heat exchange effect of the corrugated fin 100 is improved.
In an embodiment, as shown in fig. 6 and 7, each corrugated segment 110 includes a peak segment 120 and two trough segments 130, the two trough segments 130 are respectively located at two sides of the peak segment 120, and the two trough segments 130 are disposed in mirror symmetry about a center line of the peak segment 120, n corrugated segments 110 and n-1 first horizontal connection segments 140 connecting adjacent corrugated segments 110 are defined to form a corrugated set 200, the plurality of corrugated sets 200 are connected end to end along a first preset direction, and in each corrugated set 200, a cross-section center line b of the n corrugated segments 110 corresponds to a function image of y=k1sinx/x, y=k, respectively, along the first preset direction 2 sinx/x functional image … y=k n-1 sinx/x functional image and y=k n sinx/x function image, K 1 ＞K 2 ＞…＞K n-1 ＞K n 。
In the tube-fin heat exchanger, the adjacent corrugated fins 100 are clamped to form an air flow channel, and as the plurality of corrugated groups 200 of the corrugated fins 100 are connected end to end along the first preset direction, the circulation direction of the heat exchange air flow in the air flow channel is periodically changed, so that the turbulence intensity of the heat exchange air flow is enhanced, and the heat exchange effect of the heat exchange air flow and the corrugated fins 100 is improved. Further, as can be seen from the nature of the y=ksinx/x function image, the smaller the value of K is, the smaller the peak value of the corresponding peak segment 120 is, and thus, in each of the ripple groups 200, K is set along the first preset direction by setting 1 ＞K 2 ＞…＞K n-1 ＞K n So that the maximum distance from the corrugated section 110 to the reference surface is larger at the air inlet end, the disturbance effect of the corrugated set 200 on the heat exchange air flow at the air inlet end can be increased, thereby being beneficial to the heat exchange between the heat exchange air flow at the air inlet end and the corrugated fins 100, and the corrugated structure at the air outlet endThe maximum distance between the segment 110 and the reference surface is smaller, so that the disturbance action of the corrugated set 200 on the heat exchange airflow at the air outlet end can be reduced, and the heat exchange airflow subjected to heat exchange can flow from the air outlet end to the air inlet end of the corrugated set 200 at the next stage. In this way, the resistance of each stage of the bellows 200 to the flow of hot swap gas is reduced.
In one embodiment, as shown in fig. 6, n=1. In this way, the k values corresponding to the center lines of the plurality of corrugated segments 110 are equal, thereby reducing the mold manufacturing cost of the corrugated fin 100.
Further, in an embodiment, as shown in fig. 7, n=2, so that the structure of the corrugated set 200 is simplified, thereby being beneficial to reducing the processing difficulty of the corrugated set 200. In other embodiments, the value of n may be 3, 4, 5, or 6, which are not listed here.
Further, in one embodiment, as shown in fig. 6 and 7, adjacent corrugated sets 200 are smoothly connected by the second horizontal connecting section 180.

In this way, the distance between the first assembly holes 160 and the second assembly holes 170 is reduced, and the tube pitch of the heat exchange tubes is further reduced, so that more heat exchange tubes can be conveniently penetrated on the corrugated fin 100.
In another embodiment, as shown in fig. 2, the second fitting hole 170 may be provided in the corrugated section 110 spaced apart from the corrugated section 110.
In this way, the spacing between the first fitting hole 160 and the second fitting hole 170 is increased, thereby contributing to the enhancement of the structural strength of the corrugated fin 100. The spacing between the first and second fitting holes 160 and 170 may be specifically set according to actual requirements.
In one embodiment, as shown in FIG. 7, the spacing S of adjacent corrugated fins 100 along the second predetermined direction satisfies 2 mm.ltoreq.S.ltoreq.6 mm.
