A heat spreader is a component used in electronics to disperse heat evenly across a larger surface area, in order to improve thermal management and prevent hotspots from forming. Heat spreaders are commonly used in electronic chip packages, where they help to dissipate the heat generated by the chip during operation.
There are several types of heat spreaders available, including traditional flat plate designs and more complex designs with fins or other features to improve heat dissipation. Heat spreaders can be made from a variety of materials, including copper, aluminum, and various alloys. The choice of material depends on factors such as thermal conductivity, weight, and cost.
