Abstract
A method of assembling a folded-fin heat sink assembly, the assembly including base plate, a folded fin-assembly and a shroud, includes positioning the folded-fin assembly on a base plate, placing the shroud over the folded-fin assembly, urging the shroud to press the folded-fin assembly against the baze plate and bonding attached to the base plate and a shroud. According to an embodiment, the resulting shroud of the folded-fin assembly acts as extension of the folded-fin heat sink providing additional fin surfaces via which heat can be dissipated.
Claims16
A method of manufacturing a folded-fin heat sink assembly, the method comprising:
- positioning a folded-fin assembly on a base plate;
- placing a shroud over a substantial portion of the folded-fin assembly with at least part of the shroud engaging the folded-fin assembly;
- urging the shroud towards the base plate to press the folded-fin assembly against the base plate for preventing movement of folded fins of said folded-fin assembly relative to the base plate and relative to each other, and securing the shroud to the base plate with tie folded-fin assembly under pressure;
- and
- bonding the folded-fin assembly to the base plate;
- wherein the shroud includes at least a top panel, side panels and means extending downwardly from the top panel;
- wherein securing the shroud to the base plate comprises securing the side panels to the base plate;
- and
- wherein engagement of the folded-fin assembly by the shroud comprises engagement of the folded fin assembly by the downwardly extending means for maintaining the folded-fin assembly under pressure against the base plate.
