Abstract
Abstract A heat sink for conducting heat from an electronic device is disclosed. The device has a mounting base and two U-shaped members. Each U-shaped member has first and second walls integral with a top ridge. The first wall is integral with the base and extends away from the base and the second wall has a terminus portion proximate the first wall. Each U-shaped member is adapted to retain an electronic device between the first wall and the terminus portion.
