It will be understood by those skilled in the art that one or more embodiments of the present invention may be practiced without these specific details, and that numerous variations or modifications may be possible without departing from the scope of the invention. Certain details known to those of ordinary skill in the art are omitted to avoid obscuring the description.
- In the following description of the figures, any component described with regard to a figure, in various embodiments of the invention, may be equivalent to one or more like-named components described with regard to any other figure. For brevity, descriptions of these components will not be repeated with regard to each figure. Thus, each and every embodiment of the components of each figure is incorporated by reference and assumed to be optionally present within every other figure having one or more like-named components. Additionally, in accordance with various embodiments of the invention, any description of the components of a figure is to be interpreted as an optional embodiment, which may be implemented in addition to, in conjunction with, or in place of the embodiments described with regard to a corresponding like-named component in any other figure.
- Throughout the application, ordinal numbers (e.g., first, second, third, etc.) may be used as an adjective for an element (i.e., any noun in the application). The use of ordinal numbers is not to imply or create any particular ordering of the elements nor to limit any element to being only a single element unless expressly disclosed, such as by the use of the terms “before”, “after”, “single”, and other such terminology. Rather, the use of ordinal numbers is to distinguish between the elements. By way of an example, a first element is distinct from a second element, and the first element may encompass more than one element and succeed (or precede) the second element in an ordering of elements.
- As used herein, the phrase operatively connected, or operative connection, means that there exists between elements/components/devices a direct or indirect connection that allows the elements to interact with one another in some way. For example, the phrase ‘operatively connected’ may refer to any direct (e.g., wired directly between two devices or components) or indirect (e.g., wired and/or wireless connections between any number of devices or components connecting the operatively connected devices) connection. Thus, any path through which information and/or power may travel may be considered an operative connection.
- Computing devices may include any number of hardware components that facilitate providing the services of the computing devices. The hardware components may include, for example, processors, non-persistent storage drives, persistent storage drives, circuit cards that interconnect these components, etc. In some cases, computing devices might be deployed in environments that result in the temperature of the computing devices being outside of their designed operating range. For example, the computing devices may be designed to operate at temperatures above 0° C. When the computing devices are deployed to harsh environmental conditions (e.g., -40° C. - 60° C.), the computing devices may not operate properly and, in certain scenarios, may be damaged.
- To address one or more of the aforementioned issues, embodiments of the invention provide a heating mechanism to heat a peripheral component interconnect (PCI) card(s) in a computing device to a temperature that is within its designed operating range. More specifically, embodiments of the invention include a heater apparatus that is located proximate to the PCI card. The positioning of the heater apparatus enables targeted heating of the PCI card without taking up valuable space within the computing device.
