Embodiment Construction

[0016] A method and apparatus for providing heat dissipation from a PC card is disclosed. For one embodiment of the invention, a PC card is provided with an extension having a heat sink disposed thereon. The extension extends beyond the PC card slot so that heat is dissipated from the card as air flows over the heat sink. For an embodiment of the present invention, the heat-generating component of the PC card is determined, and a heat-conducting path is provided from the heat-generating component of the PC card to the extension of the PC card.

[0017] In the following description, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known circuits, structures and techniques have not been shown in detail in order not to obscure the understanding of this description.

[0018] Reference throughout this specification to "one embodiment" or "an embodiment" m...

Abstract

A method and apparatus for providing thermal dissipation from a PC card is disclosed. For one embodiment of the invention, an extension portion, having a heat sink implemented thereon, is provided for a PC card. The extension portion extends beyond the PC card slot allowing thermal dissipation from the card due to air flow over the heat sink. For one embodiment of the invention, heat producing components of the PC card are identified and a thermally conductive path is provided from the components to the extension portion of the PC card.

Description

[0001] Related Application Cross Reference [0002] This application is a non-provisional application requesting Provisional No. 60 / 671,307, entitled "Mechanism for PC Removable Module and Card Thermal Dissipation," filed April 13, 2005 Priority of the application, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] Embodiments of the present invention mainly relate to the field of personal processing equipment (PC, PDA, etc.), and more specifically, relate to a kind of PC expansion card (add-on card, add-on card) (PC card) and provide heat dissipation for PC card Methods and devices. Background technique [0004] PC Cards such as PCMCIA, 16-bit PC Card, Cradbus Card, ExpressCard, Compact Flash Card, and other PC / PDA expansion cards are manufactured in different sizes and used as expansion boards for PCs, PDAs, and the like. PC Cards generate heat that must be dissipated to avoid damaging PC components or interrupting appl...
