Description

  The present invention relates generally to fin assemblies for heat sinks, and more particularly, to fin assemblies having a plurality of fins hooked together.

  The rapid development of the computer industry increases the computing speed of electronic devices, and thus produces more heat. To maintain the allowable operating temperature of the electronic device, a heat sink having a larger area is applied to the surface of the electronic device to dissipate heat.

  However, conventional heat sinks formed by aluminum extrusion or pressing are limited due to mechanical processes. As a result, the weight of the heat sink is increased to provide more efficient heat dissipation. Thus, heat sinks typically have a plurality of relatively lightweight fins that are stacked and secured together to provide a larger area for heat dissipation.

  FIG. 7 is a perspective view of a fin assembly for a heat sink according to the related art, and FIG. 8 is an enlarged view of a portion A shown in FIG.

  The fin assembly 1a has a plurality of metal plates 10a. The metal plate 10a is given a specific shape and size by a mechanical press. Each of the metal plates 10a can be formed of, for example, aluminum or copper, and has a body member 11a, a lower edge, and an upper edge.

  The body members 11a are fixed to each other by a connecting structure 12a, as shown in FIG. Each of the connecting structures 12a has a fastening portion 120a and a connecting portion 121a. The fastening portion 120a extends vertically from a corresponding upper edge of the body member 11a. The connecting portion 121a of each body member 11a has a through hole 122a formed (perforated), and can be engaged with the fastening portion 120a of the adjacent body member 11a.

  The above connection structure provides good rigidity and stability of the fin assembly 1a, but the fin assembly 1a is too rigid and relatively inflexible. Therefore, the fin assembly 1a has a problem that it is easily damaged by an impact.

  Further, the bottom surface of the fin assembly la is limited to a planar structure. Therefore, there is a problem that the applicability of the fin assembly la is limited.

  The present invention has been made in order to solve the problems associated with the above-described conventional technology, and has as its object to provide a fin assembly for a heat sink having good flexibility and applicability. It should be noted that other objects of the present invention will become apparent to those skilled in the art after understanding the following detailed description of the preferred embodiments of the present invention.

  According to an embodiment of the present invention, there is provided a fin assembly having a plurality of metal plates stacked on each other. Each of the metal plates has a body member and a plurality of connecting structures projecting vertically from the body member. Each of the body members has a plurality of through holes.

  Each of the articulation structures has a partition portion and a latch portion extending from the partition portion, and the latch portion is aligned with the corresponding through hole. The latch portion inserted into the corresponding through hole in the metal plate arranged in the front is bent and functions as a hook. Preferably, each of the body members has two bent edges extending along the longitudinal direction, the bent edges being perpendicular to the body member.

  The present invention configured as described above can provide a fin assembly for a heat sink having good flexibility and applicability.

  For example, the metal plates are fixed to each other by a hook member (connecting structure) formed integrally with the metal plate. Therefore, the connection strength and stability of the fin assembly can be improved. Further, the bottom structure is adapted to the surface shape of the heat sink or the electronic device.

  It will be understood that the foregoing general description and the following detailed description are by way of example only and are intended to further explain the invention in accordance with the utility model registration claims.

  The above and other features of the present invention will become more apparent with reference to the accompanying drawings. Reference will also be made in detail to the preferred embodiments of the present invention, embodiments of which are illustrated in the accompanying drawings. Furthermore, where possible, the same reference numerals will be used in the drawings and description to refer to the same or analogous parts.

  FIG. 1 is a perspective view of a metal plate of a heat sink fin assembly according to an embodiment of the present invention, FIG. 2 is a perspective view of a fin assembly formed by stacking the metal plates of FIG. 1, and FIG. 3 is an enlarged view of a portion A shown in FIG.

  As shown in FIG. 2, the fin assembly 1 according to the present invention has a plurality of metal plates 10 arranged in parallel with each other. Each of the metal plates 10 is formed by a mechanical fishing press and has a predetermined shape and size. The cross section of the shape includes, for example, an open rectangle, an L-shape, and an I-shape.

  In the present embodiment, each of metal plates 10 has body member 11 and two bent edges (upper bent edge and lower bent edge) 110 and 111. The bent edges 110 and 111 extend in the vertical direction from edges of the opposing long sides of the body member 11 (extending along the longitudinal direction).

  The shape of the metal plate 10 is not limited to an open rectangular shape, an L-shape, or an I-shape, and may be modified by a person skilled in the art into other shapes without departing from the scope of the claims for utility model registration. It will be appreciated that it is possible.

  As shown in FIGS. 1 to 3, each of the metal plates 10 has a plurality of connecting structures 12. In the present embodiment, the connecting structures 12 are arranged at four corners on the diagonal line of each body member 11 of the metal plate 11.

  As clearly shown in FIG. 3, the connecting structure 12 is a part of the body member 11. That is, the connecting structure 12 is formed integrally with the body member 11 at the time of mechanical pressing. Preferably, each of the articulation structures 12 has a plate which is released (formed) from the corresponding body member 11 by pressing.

  The plate projects vertically from the body member 11. As a result, an opening 112 corresponding to the plate is formed in the body member 11. In the present embodiment, the plate has a partition part 120 and a latch part 121 extending from the partition part 120.

  As described above, each of the plates can be bent in a direction perpendicular to the body member 11 after being released from the body member 11 by pressing. The partition part 120 of the plate secures a space required between the adjacent metal plates 10. Each of the body members 11 further has a perforated hole 113 aligned with the latch member 121 of the plate. The number of through holes 113 is preferably the same as the number of connecting structures 12.

  As shown in FIG. 4, latch members 121 are inserted into corresponding through holes 113 in the nearest (front) metal plate 10 to secure the metal plates 10 together. Then, the latch members 121 protruding from the adjacent metal plates 10 are bent by a tool, function as hooks, and fix the metal plates 10 to each other. That is, since the metal plates 10 are fixed to each other by the hook members (connecting structures) formed integrally with the metal plate 10, the connection strength and stability of the fin assembly 1 can be improved.

  Thus, a heat sink fin assembly is formed.

  FIG. 5 is a plan view of the fin assembly for a heat sink according to the embodiment of the present invention, and FIG. 6 is an enlarged view of a portion A shown in FIG.

  As shown in FIGS. 5 and 6, the connecting structure 12 has a connecting part 122 between the partition part 120 and the latch member 121. The length of the connecting portion 122 can be appropriately adjusted according to the thickness of the body member 11 and the width required for the space between the adjacent metal plates 10.

  When the length of the connection part 122 is the same as the thickness of the body member 11, the partition part 120 and the latch part 121 are very close to the body member 11 of the adjacent metal plate 10. As a result, a strong stacking effect can be obtained. On the other hand, when the length of the connecting portion 122 is larger than the thickness of the body member 11, good flexibility is obtained. Therefore, the bottom surface of the fin assembly 1 can be curved into various shapes. That is, the bottom structure of the fin assembly 1 can be adapted to the surface shape of the heat sink or the electronic device.

  Further, the connecting structure 12 uses the latch member 121 to hook the body member 11 of the adjacent metal plate 10 and fasten it to the front of the through hole 113. Therefore, the frontmost metal plate 10 does not require the connecting structure 12. Alternatively, the connecting structure 12 does not need to protrude from the metal plate 10.

  As described above, the present embodiment can provide a fin assembly for a heat sink having good flexibility and applicability.

  While the invention has been disclosed in connection with the above variations and embodiments, additional modifications will now be apparent to those skilled in the art. The present invention is not intended to be specifically limited to the above-described variations, but rather demands exclusive rights with reference to the claims of the utility model registration, rather than the above description of the preferred embodiments. The scope of the utility model registration claims should be evaluated.
