Abstract
The present invention relates to a cooling fin assembly suitable for heat sinks. In one embodiment, the cooling fin assembly (10) includes a plurality of cooling fins (10a) joined together. Each of the cooling fins includes a main body (11a) forming four engaging members (14a) at four corners thereof respectively. Each of the engaging members including a roll piece (15a) with an elongated hole (16a) defined therein and a connecting piece (17a) with an engaging piece (18a) extending therefrom. In assembly of the cooling fins, the engaging pieces of each of the cooling fins engage in the corresponding holes of the roll pieces of an adjacent cooling fin to thereby fasten and join the cooling fins with one another.
Claims14
A cooling fin assembly comprising a plurality of cooling fins stacked between two opposite outmost cooling fins, each of the plurality of cooling fins comprising a main body with a plurality of engaging members formed thereon, each of the engaging members comprising a roll piece with a hole defined therein and a connecting piece with an engaging piece extending therefrom, wherein the engaging pieces of each of the plurality of cooling fins engage in corresponding holes of the roll pieces of an adjacent cooling fin whereby the cooling fins are fastened and joined together.
A method for forming a cooling fin assembly comprising the steps of:
- a) providing a plurality of cooling fins each having a plurality of engaging members, each engaging member comprising a roll piece with an elongated hole defined therein and a connecting piece with an engaging piece extending therefrom;
- and
- b) combining every two adjacent cooling fins by expanding the connecting piece of each engaging member of one cooling fin outwardly to cause the engaging piece thereof to be capable of engaging in the hole of the roll piece of a corresponding engaging member of the other cooling fin.
A cooling fin assembly comprising:
- a plurality of cooling fins arranged parallel to each other, every two of said fins adapted to form a heat dissipation space therebetween so as to allow air flow passing through said space along a specialized direction;
- a first engaging portion extending from one of said fins;
- and
- a second engaging portion extending from said one fin and located approachably to said first engaging portion of another fin next to said one fin, said one fin fixable to said another fin by means of engagement of said second engaging portion of said one fin and said first engaging portion of said another fin along said specialized direction of said air flow.
