Abstract
Thermal management systems are described herein. A thermal management system includes components of a computing device. The computing device includes a heat generating component and a heat spreader physically connected to the heat generating component. The heat spreader includes a first surface and a second surface. The second surface is closer to the heat generating component than the first surface is to the heat generating component. The computing device also includes a layer of phase change material on at least a portion of the first surface, the second surface, or the first surface and the second surface of the heat spreader.
Claims20
A computing device comprising:
- a heat generating component;
- a heat spreader physically connected to the heat generating component, the heat spreader comprising a first surface and a second surface, the second surface being closer to the heat generating component than the first surface is to the heat generating component;
- and
- a layer of phase change material on at least a portion of the first surface, the second surface, or the first surface and the second surface of the heat spreader.
A computing device comprising:
- a housing;
- a heat generating component supported by the housing;
- a heat pipe comprising a first surface and a second surface, the second surface of the heat pipe abutting or being adjacent to the heat generating component;
- a heat spreader comprising a first surface and a second surface, the heat spreader being physically connected to the heat pipe and the second surface of the heat spreader being closer to the first surface of the heat pipe than the first surface of the heat spreader is to the first surface of the heat pipe;
- and
- a layer of phase change material covering at least a portion of the first surface of the heat spreader.
A thermal management device comprising:
- a phase change device;
- a heat spreader physically attached to the phase change device, the heat spreader comprising a first surface and a second surface, the second surface of the heat spreader being closer to the phase change device than the first surface of the heat spreader is to the phase change device;
- a first layer of phase change material covering a first portion of the first surface of the heat spreader;
- and
- a second layer of phase change material covering a second portion of the first surface of the heat spreader,
- wherein the first layer of phase change material is a different size than the second layer of phase change material, the first layer of phase change material is made of a different material than the second layer of phase change material, or a combination thereof.
