Collapsible Mobile Exhaust System

Disclosed is a device that improves mobile heat dissipation and further separates mobile heat elements from the user. Improved heat dissipation directly affects the design and functionality of a mobile device. Further separating mobile heat elements from a mobile user improves usability and user satisfaction.

"Realestate" in mobile design terms refers to physical space for mobile components. Examples of mobile components may include chassis', ports, drives, batteries, displays, fans, motherboards, memory, input keypad, vents, heatsinks, etc. The smaller the mobile device, the less realestate a designer has to work with. In addition, designers who want to use high temperature components are usually forced to place these components near vents, fans, heatsinks, or other heat dissipation device. Limited realestate for heat dissipation devices plus high temperature components strictly limits what can be safely designed and implemented.

Users have heat tolerances. For example, a mobile computer user may tolerate a mobile device that is warm or even hot to the touch. In most circumstances, the user would prefer less mobile heat output. It makes the mobile device more comfortable and more convenient to use.

Mobile components also have heat tolerances. For example, a mobile CPU may operate correctly from 40-90 degrees Fahrenheit. If the mobile heat dissipation is not sufficient and the CPU is subject to 95 degrees Fahrenheit, the CPU may perform erratically or fail to operate. In general, operating components in temperatures higher than they were designed for shortens their operational life.

The disclosed device is based on a collapsible space. On one side of the space is a heatsink, on the other side is a heat rejecting material. The air in the space between these surfaces would optimally be blown by a fan or fans. This collapsible design allows the mobile device to occupy minimal space when not in operation or while it is being transported. The heatsink on one side of the space allows for mobile components to be grounded to it. The heat rejecting material on the other side would keep the heat away from the mobile user. The space between the sides with fan assist significantly impacts th...
