US 11,599,168 B2 · Extended thermal battery for cooling portable devices

Abstract

A cooling system for cooling components in an information handling system contained in a portable chassis comprises a die plate for receiving heat from a component, a heat pipe for transferring heat from the die plate to a single heat exchanger, a fan for generating an airflow across the heat exchanger and a thermal battery. The heat pipe comprises at least one curvature and the thermal battery is coupled to the die plate and has a length and a width such that the thermal battery is in contact with the heat pipe from the die plate to a point past the at least one curvature. The thermal battery may be formed from a thermally conductive material, be a vapor chamber or otherwise facilitate heat transfer to a heat pipe from the die plate to a point past the curvature for improved cooling.
