Abstract

A heat sink housing for electronic components comprises a metal tube having four walls formed with internal and external ridges and grooves. The inside ridges and grooves removably support circuit boards and separate circuit members. The external ridges maximize radiation of heat from inside the tube. Two cover plates are removably attached to open ends of the tube to form a closed compartment in the tube.
