PORTABLE ELECTRONIC DEVICE THERMAL MANAGEMENT SYSTEM

摘要

An electronic device having a heat source disposed in direct alignment with a battery for the device and a thermal management system in thermal contact with the heat source. The thermal management system may extend from at least a first surface of the battery to a second surface of the battery. The second surface of the battery may be adjacent a heat dissipation element. The thermal management system may further be in thermal contact with the heat dissipation element. Further a portion of the thermal management system extends along the first and second surfaces of the battery and has a sufficiently high anisotropic ratio to avoid the transfer of heat to the battery to the extent to inhibit the functioning of the battery.

主权项

1. An electronic device comprising
a. a heat source disposed in direct alignment with a battery for the device, b. a thermal management system in thermal contact with the heat source,
i. the thermal management system extending to at least a first surface of the battery, c. a portion of the thermal management system extends along the first surface and a second surface of the battery, the portion being in thermal communication with a plurality of cells of the battery and the portion having a sufficiently high spreading coefficient to avoid the creation of a localized hot spot in one of cells to such magnitude to inhibit the function of the battery, and d. the battery and the system spaced apart from the external surface of the device.
