Abstract
A power adapter includes a housing formed of a bottom cover shell and a top cover shell and having an air passage extending across the bottom cover shell and an exhaust port in the top cover shell, a PC board mounted in the housing, two heat sinks covered on the PC board for absorbing heat from the primary and secondary sides of the PC board respectively for enabling absorbed heat to be carried to the outside of the housing by outside cooling air that is circulating through the exhaust port and the air passage, and a spacer set in the air passage between the heat sinks and working with the heat sinks to protect the PC board against outside dust and water.
