Abstract
In the embodiments of the present disclosure, a device having time division multiplexing capability of heat dissipation is provided, including: a first component and a second component arranged in different orientations; and a heat sink arranged to guide an air flow flowing through the heat sink to the first component and the second component respectively during different time periods. Therefore, the device having time division multiplexing capability of heat dissipation of the present disclosure may reduce the number of heat sinks in the device and thus, reduce the overall size of the device.
Claims20
A device comprising:
- a housing comprising a first side and a second side;
- one or more temperature sensors;
- and a rotatable heat sink arranged to modify a direction of an air flow flowing through the rotatable heat sink from the first side of the housing toward the second side of the housing based at least in part on one or more temperature measurements made by the one or more temperature sensors and thermal performance requirements of two or more components arranged in two or more different air flow paths from the first side of the housing toward the second side of the housing;
- wherein a first one of the two or more components is arranged in a first one of the two or more different air flow paths from the first side of the housing toward the second side of the housing;
- wherein a second one of the two or more components is arranged in a second one of the two or more different air flow paths from the first side of the housing toward the second side of the housing;
- wherein the rotatable heat sink is mounted to a third component and arranged to modify the direction of the air flow between the first air flow path and the second air flow path.
