Abstract

The invention relates to a heat dissipation device with a bracket for dissipating heat of a heating element of an expansion card. The heat dissipation device also includes an auxiliary card, a heat dissipating element. The bracket includes a securing element configured for securing the heat dissipating element thereto, a locking element, and a connecting element connecting the securing element to the locking element. The securing element clamps the expansion card, and the locking element is slidably mounted to the auxiliary card, to align the heat dissipating element with the heating element of the expansion card.

Claims

1. A heat dissipation device for dissipating heat of an expansion card, the heat dissipation device comprising:

an auxiliary card;

a heat dissipating element; and

a bracket comprising a securing element, for securing the heat dissipating element thereto, a locking element, and a connecting element that connects the securing element to the locking element;

wherein the securing element attaches to the expansion card, and the locking element is adjustably mounted to the auxiliary card and wherein a guide groove is defined in an end of the auxiliary card, a guide hole is formed at an end of the guide groove, and a guide rail is extended from an end of the locking element;

wherein the guide rail is capable of being inserted into to the guide hole.

2. The heat dissipation device as claimed in claim 1, wherein the securing element defines an opening therein, the connecting element includes two parallel connecting plates, and a side of the locking element is connected to a rim of the opening via the connecting plates.

3. The heat dissipation device as claimed in claim 2, wherein two clamp portions protrude from a side of the securing element at opposite sides of the opening;

wherein the clamp portions are capable of attaching to the expansion card.

4. The heat dissipation device as claimed in claim 3, wherein each of the clamp portions comprises an L-shaped portion, and an arm portion horizontally extending from the securing element on the opposite side of the L-shaped portion relative to the opening.

5. The heat dissipation device as claimed in claim 1, wherein the heat dissipating element is a blower.

6. The heat dissipation device as claimed in claim 1, wherein the expansion card and the auxiliary card are peripheral component interconnect (PCI) expansion cards.
