Definitions

  • the present disclosure relates to a heat sink assembly.
  • Fins of a heat sink are always made of metal. In assembly, corners of the fins are a source of injury to an operator. In transportation, the corners of the fins are vulnerable to deformation and damage.
  • FIG. 1 is an assembled, isometric view of an exemplary embodiment of a heat sink assembly, wherein the heat sink assembly includes a heat sink and four protecting members.
  • FIG. 2 is an isometric view of the heat sink of FIG. 1 .
  • FIG. 3 is an enlarged view of one of the protecting members of FIG. 1 from another perspective.
  • FIG. 1 shows an exemplary embodiment of a heat sink assembly including a heat sink 10 and four protecting members 20 .
  • the heat sink 10 includes a base 12 , a plurality of heat pipes 14 perpendicularly connected to the top of the base 12 , and a plurality of fins 16 perpendicularly connected to the heat pipes 14 .
  • Each fin 16 is quadrate and includes four corners.
  • the fins 16 are parallel to the base 12 , and aligned and overlapped with one another to form a rectangular fin assembly, square in cross section, which includes four lengthwise corners at lateral sides of the fin assembly.
  • Each lengthwise corner is formed by a plurality of overlapped corners of the fins 16 .
  • each protecting member 20 is made of plastic, and includes an elongated first stop plate 21 , and an elongated second stop plate 23 perpendicularly extending from a longitudinal side of the first stop plate 21 .
  • a plurality of pairs of connecting plates 25 is perpendicularly connected between the inner sides of the first and second stop plates 21 and 23 , arranged at opposite ends of the first and second stop plates 21 and 23 .
  • a slot 251 is bounded by each pair of connecting plates 25 .
  • the protecting member 20 as a whole presents the appearance of a rack or frame for holding objects in an orderly fashion.
  • the first and second stop plates 21 and 23 of each protecting member 20 are arranged to be perpendicular to the fins 16 .
  • the four protecting members 20 are respectively fixed to the four lengthwise corners of the fin assembly, to allow the upper slots 251 to take the corners of several fins 16 on the upper portion of the heat sink 10 into engagement, and to allow the lower slots 251 to take the corners of several fins 16 on the lower portion of the heat sink 10 into engagement.
  • the first and second stop plates 21 and 23 of each protecting member 20 abut two adjacent sides of the fin assembly.
  • the four lengthwise corners of the heat sink 10 are covered by the protecting members 20 , removing and insulating any sharp corners of the fin assembly as a source of injury.
  • the corners of the fins 16 on the upper and lower portions of the heat sink 10 are firmly engaged in the upper and lower slots 251 of the four protecting members 20 , the connecting plates 25 function as a support and shield for the corners of all the fins 16 and protect all fins 16 from damage or being deformed when the heat sink 10 suffers impact or crushing forces.
