Manifold for a liquid cooling system

Abstract

A method including punching a first hole in a parent sheet metal, such that a substantially round section with a first diameter is removed from the hole, forming a second hole by inserting a mandrel into the first hole, causing a portion of the parent sheet metal to deform in a downward direction and increase the diameter of the first hole to a second diameter, the deformed portion of the parent sheet metal is substantially perpendicular to the parent sheet metal, forming a thread into an interior sidewall of the second hole, and forming the parent sheet metal into a water tight manifold.

1 - 16 . (canceled) 
     
     
         17 . A structure comprising:
 a watertight manifold fabricated from a piece of sheet metal and having a welded seam and a threaded hole extrusion; and   a threaded quick connect fitting, the quick connect fitting has an o-ring which is threaded into the threaded hole extrusion such that the o-ring is in direct contact with a substantially uniform surface of the watertight manifold.   
     
     
         18 . The method of  claim 17 , wherein an inside diameter of the threaded hole extrusion is approximately a minimum of four times a height of the threaded hole extrusion. 
     
     
         19 . The method of  claim 17 , wherein a height of the threaded hole extrusion is at least three times a pitch of the thread. 
     
     
         20 . The method of  claim 17 , wherein a wall thickness of the threaded hole extrusion is at least two times a difference between a major diameter of the thread and a minor diameter of the thread.
