[0002] A phase change radiator generally includes a base and a plurality of phase change fins fixed to the base. The number of connection ports between the phase change fins and the base is large, and the internal channels of the fins and the base are connected together. Once leakage occurs, this area of the radiator will fail. Therefore, most of them have extremely high requirements for welding reliability.

[0003] However, in practical applications, most of the fins are blow-up plates, with a thickness of only 0.8 mm and made of 1-series aluminum. Its material is soft, and it is prone to lateral deflection after heating and cooling. And it is easily deformed in the ball-drop and angle steel collision tests. The deformation of the fins will also affect the reliability of the bottom solder joints. Summary of the Invention

[0004] Embodiments of this application provide a fin radiator, which reduces the deformation amount of the fins by increasing the structural stiffness and can realize the standardization of the fins.

[0005] In an embodiment of this application, a fin radiator is provided, including: A base; A plurality of fins arranged in parallel at equal intervals, and the bottom of each fin is fixedly connected to the base to support on the base; Wherein, the top end of the fin includes a fin top buckle plate, and the fin top buckle plate includes: A plate-shaped body, the plate-shaped body extends from the top end of the fin towards the first side of the fin, the plate-shaped body is perpendicular to the direction of the fin, the plate-shaped body is formed in a rectangular shape, the width direction of the plate-shaped body is perpendicular to the extension direction of the fin, the width of the plate-shaped body corresponds to the distance between two adjacent fins, and the plate-shaped body has a first end edge and a second end edge extending along the length direction of the plate-shaped body, and the first end edge is connected to the top of the fin; A buckle, the buckle is arranged on the second end edge; Wherein, the buckle is clamped with the top of an adjacent fin to clamp the plate-shaped body between two adjacent fins.

[0006] In an example, the buckle is formed in a hook shape extending from the second end edge along a direction perpendicular to the plate-shaped body.

[0007] In an example, the fin includes a first fin and a second fin, and the second fin is located on the first side of the first fin. Wherein, the buckle of the first tooth piece clamps the surface of the second tooth piece facing away from the first tooth piece, so as to clamp the plate-shaped body of the first tooth piece between the first tooth piece and the second tooth piece.

[0008] In one example, the plate-shaped body has a first card slot, and the first card slot is opened at the first end edge; In the length direction of the plate-shaped body, the position of the first card slot corresponds to the position of the buckle.

[0009] In one example, the midpoint of the first card slot corresponds to the midpoint of the first end edge.

[0010] In one example, the top of each tooth piece has a groove for accommodating the plate-shaped body, the depth of the groove corresponds to the thickness of the plate-shaped body, and the first end edge of the plate-shaped body is in contact with the bottom surface of the groove.

[0016] In this example, the tooth top buckles are arranged at the positions where there is no support at the top of the tooth piece. Among them, each tooth top buckle is connected between two adjacent tooth pieces, used to define the distance between two adjacent tooth pieces, and improve the structural strength by establishing a connection structure between two adjacent tooth pieces.

[0029] The embodiment of the present application provides a fin radiator, which reduces the deformation amount of the fins by increasing the structural stiffness and can realize the standardization of the fins.

[0030] Exemplary embodiments will now be described more fully with reference to the accompanying drawings.

[0031] As Figures 1 to 2 shown, an embodiment of the present application provides a fin heat sink. The fin heat sink 1 includes a base 3 and a plurality of fins 2 that are supported on the base 3 and arranged in parallel at equal intervals. The bottom of each fin 2 is fixedly connected to the base 3 to be supported on the base 3.

[0032] Among them, the top of the fin 2 includes a fin top buckle 4, and the fin top buckle 4 includes: a plate-shaped body 10 that extends from the top of the fin 2 toward the first side of the fin 2. The plate-shaped body 10 is perpendicular to the fin 2. The width direction of the plate-shaped body 10 is perpendicular to the extension direction of the fin 2. The width of the plate-shaped body 10 corresponds to the spacing between two adjacent fins 2. The plate-shaped body 10 includes a first end edge 11 and a second end edge 12 that extend along the length direction of the plate-shaped body 10. The plate-shaped body 10 is connected to the top of the fin 2 through the first end edge 11; a buckle 22 that is provided on the second end edge 12; Among them, the buckle 22 is used to be clamped with the top of an adjacent fin 2 to clamp the plate-shaped body 10 between two adjacent fins 2.

[0033] In this example, the bottom of the fin 2 of the fin heat sink 1 is fixedly connected to the base 3. If the top is in a suspended and unsupported state, problems such as deformation and distortion are likely to occur when the material texture of the fin 2 is relatively soft, especially at the position near the top, which is likely to cause the solder joints at the welding position between the bottom of the fin 2 and the base 3 to crack.

[0034] To solve the above problems, the industry usually rivets and embeds a cover plate on the fin top, which can not only increase the heat dissipation area but also cooperate with the characteristics of the louver holes on the cover plate that only allow air to enter but not exit to achieve the chimney effect to further improve the heat dissipation performance. However, this transformation has high costs, complex processes, and the appearance of the cover plate cannot be adapted to all fin heat sinks. Moreover, the press riveting may have a larger thermal resistance and poorer heat conduction than welding, so the heat dissipation effect of the cover plate is not ideal.

[0035] In this example, a fin top buckle 4 is provided at the unsupported position at the top of the fin 2. Among them, each fin top buckle 4 is connected between two adjacent fins 2 and is used to limit the spacing between two adjacent fins 2, and the structural strength is improved by establishing a connection structure between two adjacent fins 2. Support structures are provided at both the top and bottom of the fin 2, thereby greatly reducing the degree of deformation of the fin 2.

[0036] Specifically, the tooth top buckle plate 4 includes a plate-shaped body 10 and a buckle 22 located at the second end edge 12 of the plate-shaped body 10. Among them, the width direction of the plate-shaped body 10 is perpendicular to the extending surface of the tooth piece 2, and the length direction is consistent with the extending direction of the tooth piece 2. Here, the width of the plate-shaped body 10 is not limited to being less than the length, but is only set for distinction, only to illustrate that the buckle 22 is set at one long side of the plate-shaped body 10 to lap and support the adjacent tooth piece 2.

[0037] Among them, the plate-shaped body 10 and the tooth piece 2 are integrally formed and extend toward the first side of the tooth piece 2 (i.e., one side of the adjacent tooth piece 2). The buckle 22 is clamped with the top of the adjacent tooth piece 2, so that the plate-shaped body 10 is clamped between two adjacent tooth pieces 2. Then, the width of the plate-shaped body 10 corresponds to the distance between the two tooth pieces 2, thereby realizing the limitation of the distance between the two tooth pieces 2 and the support for the two tooth pieces 2.

[0038] Specifically, the buckle 22 is formed as a hook shape extending along a direction perpendicular to the plate-shaped body 10 from the second end edge 12.

[0039] In the direction perpendicular to the extending surface of the tooth piece 2, the cross-section of the tooth top buckle plate is formed in an L shape, together with the tooth piece 2 to form a U shape, and the opening of the U shape faces the direction of the base 3 of the tooth piece radiator 1, and is buckled on the top of the tooth piece radiator 1 in a manner similar to a cover plate. Among them, there is only one limitation on the size of the tooth top buckle plate, that is, the width of the plate-shaped body 10 corresponds to the distance between the two tooth pieces 2, and there are no rigid requirements for the length of the plate-shaped body 10, the width and length of the buckle 22, etc. And only one action is required to complete the installation of each tooth top buckle plate, that is, to clamp the buckle 22 with the top of the adjacent tooth piece 2. And only one corresponding tooth piece 2 needs to be aligned, and the installation requirements and transformation costs are very low.

[0040] In this example, the whole of the tooth top buckle plate can be made of a metal material with good heat dissipation performance, and its hardness should be higher than or equal to the material of the tooth piece 2. In a preferred example, the width of the plate-shaped body 10 can be slightly smaller than the distance between the two tooth pieces 2. Then, when the buckle 22 is clamped with the two tooth pieces 2, the two tooth pieces 2 can be elastically deformed toward each other, so that the two tooth pieces 2 and the tooth top buckle plate can be fastened by the elastic deformation of the two tooth pieces 2 to achieve a tight connection.

[0041] Among them, in a pair of tooth pieces 2, it includes a first tooth piece 2a and a second tooth piece 2b. The buckle 22 of the first tooth piece 2a clamps the surface of the second tooth piece 2b facing away from the first tooth piece 2a to clamp the plate-shaped body 10 between the first tooth piece 2a and the second tooth piece 2b.

[0042] It can be understood that the fixation between a pair of tooth plates 2 can be achieved by only one tooth top buckle plate. Due to the requirements of heat dissipation and ventilation, the length of the tooth top buckle plate is necessarily less than the length of the tooth plate 2 to avoid covering the entire top surface of the tooth plate radiator 1. It is also possible to achieve fixation by multiple tooth top buckle plates arranged at intervals along the extending surface of the tooth plate 2 (i.e., the length direction of the plate-shaped body 10) to improve the structural stiffness.

[0043] Since the tooth top is directly bent and integrally connected to the tooth plate substrate, the hook-shaped part has a good heat transfer effect. In necessary cases, only by increasing the area of the plate-shaped body 10 without increasing the height and width of the radiator, the effect of increasing the tooth height can be achieved. Therefore, this point can be utilized to match the tooth height of the tooth plate radiator.

[0044] Meanwhile, in a tooth plate radiator 1, since it includes multiple tooth plates 2 arranged at equal intervals, how to arrange the positions of two adjacent tooth top buckle plates becomes the key to determining the heat dissipation performance, appearance aesthetics, and installation and modification difficulty of the tooth plate radiator.

[0045] In a specific example, the plate-shaped body 10 includes a first card slot 23, and the first card slot 23 is opened at the first end edge 11. In the length direction of the plate-shaped body 10, the position of the first card slot 23 corresponds to the position of the buckle 22.

[0046] The tooth plate 2 includes, for example, adjacent first tooth plate 2a, second tooth plate 2b, and third tooth plate 2c. The second tooth plate 2b and the third tooth plate 2c are located on the first side of the first tooth plate 2a, and the third tooth plate 2c is located on the first side of the second tooth plate 2b. Among them, the tooth top buckle plate 4 of the first tooth plate 2a is used to connect between the first tooth plate 2a and the second tooth plate 2b, and the tooth top buckle plate 4 of the second tooth plate 2b is used to connect between the second tooth plate 2b and the third tooth plate 2c. The two tooth top buckle plates must avoid each other to achieve installation, which poses new requirements for the length of the plate-shaped body 10, the installation difficulty of the entire tooth top buckle plate, and the overall appearance of the tooth plate radiator.

[0047] In this example, the plate-shaped body 10 forms a first card slot 23 for accommodating the buckle 22 at the first end edge 11. Then, the buckle 22 of the tooth top buckle plate 4 of the first tooth plate 2a used to connect between the first tooth plate 2a and the second tooth plate 2b can be accommodated in the first card slot 23 of the tooth top buckle plate 4 of the second tooth plate 2b used to connect between the second tooth plate 2b and the third tooth plate 2c, and the buckle 22 of the tooth top buckle plate 4 of the second tooth plate 2b can be accommodated in the first card slot 23 of the tooth top buckle plate 4 of the third tooth plate 2c. Then, in the entire tooth plate radiator 1, the tooth top buckle plates can be aligned with each other to form a continuous shape to integrally improve the structural stiffness and improve the appearance.

[0048] Among them, the midpoint of the first card slot 23 corresponds or does not correspond to the midpoint of the first end edge 11.

[0049] Each top of the tooth piece 2 has a groove 2d for accommodating the plate - shaped body 10. The depth of the groove 2d corresponds to the thickness of the plate - shaped body 10, and the first end edge 11 of the plate - shaped body 10 is in contact with the bottom surface of the groove 2d. There is a vertically protruding clamping plate 21 in the groove 2d. The upper edge of the clamping plate 21 is flush with the tooth piece 2, and the position of the clamping plate 21 corresponds to the position of the buckle 22, and the buckle 22 is clamped on the clamping plate 21.

[0050] The plate - shaped body 10 is used to support a pair of adjacent tooth pieces 2 and is also used to dissipate the heat from the tooth pieces 2 through the plate - shaped body 10. Then the plate - shaped body 10 can be formed into a flat plate body without a hollow. In order to improve the heat dissipation effect, the hollow area at the top of the fin radiator 1 should be ensured. In a preferred example, the hollow area at the top of the fin radiator 1 should be ensured to be greater than half of the top area of the fin radiator 1. Specifically, the sum of the lengths of multiple tooth - top buckles is less than or equal to half of the length of the tooth piece 2.

[0051] In another example, the plate - shaped body 10 has a plurality of ventilation slots 13. The ventilation slots 13 penetrate the plate - shaped body 10 along the thickness direction of the plate - shaped body 10, and the plurality of ventilation slots 13 are arranged at equal intervals along the length direction of the plate - shaped body 10.

[0052] The plurality of ventilation slots 13 are arranged along the length direction to form a structure of louver holes, and then ventilation and heat dissipation can be achieved through the chimney effect. The chimney effect refers to the phenomenon that indoor air rises or descends along a vertically sloping space, causing enhanced air convection. The generation of the chimney effect is a phenomenon in buildings and structures (such as water towers) with a smooth circulation space from bottom to top, where air (including flue gas) diffuses or is discharged from the building quickly due to the action of density difference, which is a manifestation of a form of heat exchange. In this example, a vertical circulation space can be formed between two tooth pieces 2, and a heat - dissipation air flow can be formed that enters cold air from the opening in the height direction between the two tooth pieces 2 and the hot air leaves through the ventilation slots 13.

[0053] In order to improve the heat dissipation effect, the hollow area at the top of the fin radiator 1 should be ensured. In a preferred example, the hollow area at the top of the fin radiator 1 should be ensured to be greater than half of the top area of the fin radiator 1.

[0054] Specifically, the sum of the dimensions of the plurality of ventilation slots 13 along the length direction of the plate - shaped body 10 is greater than or equal to half of the length of the plate - shaped body 10.

[0055] Another embodiment of the present application also provides a fin radiator 1, including: A base 3; A plurality of equally spaced and parallelly arranged tooth pieces 2, the bottom of each tooth piece 2 is fixedly connected to the base 3 to be supported on the base 3; and A tooth top buckle plate, which is installed on the top of the tooth piece 2; Wherein, the top of each tooth piece 2 has a groove 2d for accommodating the plate-shaped body 10, and the depth of the groove 2d corresponds to the thickness of the plate-shaped body 10.

[0056] The first end edge 11 of the plate-shaped body 10 is connected to the groove 2d so that the plate-shaped body 10 is accommodated in the groove 2d and is clamped between two tooth pieces 2. Then, the width of the plate-shaped body 10 corresponds to the spacing between two tooth pieces 2, thereby realizing the limitation of the spacing between two tooth pieces 2 and the support for the two tooth pieces 2.

[0057] When the plate-shaped body 10 is formed as a flat plate body without a hollow, in order to improve the heat dissipation effect, the hollow area at the top of the tooth piece radiator 1 should be ensured. In a preferred example, the hollow area at the top of the tooth piece radiator 1 should be ensured to be greater than half of the top area of the tooth piece radiator 1. Specifically, between two adjacent tooth pieces 2, there are a plurality of tooth top buckle plates, and the plurality of tooth top buckle plates are arranged at intervals along the length direction of the plate-shaped body 10, and the sum of the lengths of the plurality of tooth top buckle plates is less than or equal to half of the length of the tooth piece 2.

[0058] In another example, each tooth piece 2 may include a plurality of tooth top buckle plates, and the plurality of tooth top buckle plates 4 are arranged at intervals along the length direction of the plate-shaped body 10; The plate-shaped body 10 has a plurality of ventilation slots 13, and the ventilation slots 13 penetrate the plate-shaped body 10 along the thickness direction of the plate-shaped body 10, and the plurality of ventilation slots 13 are arranged at equal intervals along the length direction of the plate-shaped body 10; Wherein, there is an air inlet part between two adjacent tooth pieces 2, and the air inlet part includes the intervals between a plurality of tooth top buckle plates and the ventilation slots, and the length of the air inlet part is greater than or equal to half of the length of the tooth piece 2.

[0059] In a specific example, all the tooth top buckle plates in the tooth piece radiator 1 are formed as flat plate bodies without a hollow, then the overall area of the tooth top buckle plates is less than or equal to half of the top area of the tooth piece radiator 1. Correspondingly, the sum of the lengths of the plurality of tooth top buckle plates is less than or equal to half of the length of the tooth piece 2.

[0060] In a specific example, at least part of the tooth top buckle plates in the tooth piece radiator 1 are formed as flat plate bodies with a hollow, then the hollow area at the top of the tooth piece radiator 1 is less than or equal to half of the top area of the tooth piece radiator 1. Correspondingly, the length of the air inlet part is greater than or equal to half of the length of the tooth piece 2.

[0061] In this example, a top tooth buckle plate is provided at the position where the top of the tooth piece 2 is not supported. Each top tooth buckle plate is arranged between two adjacent tooth pieces 2 and is used to define the spacing between two adjacent tooth pieces 2, thereby improving the structural strength by establishing a connection structure between two adjacent tooth pieces 2. Support structures are provided at both the top and bottom of the tooth piece 2, thus greatly reducing the degree of deformation of the tooth piece 2.

[0062] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
