Abstract: A device mounting apparatus includes a mounting base portion having a plurality of opposing pairs of rails. The mounting base portion is adapted for mounting on a support structure. The apparatus further includes a mounting tab affixed to a device for snap in mounting between a pair of rails, whereby the device is captively retained on the mounting base portion, and can be disengaged therefrom by snapping the mounting tabs out of the associated pairs of rails.

Abstract: A process for making a multilayer plastic tube heat exchanger with a ribbon of molten polymer being poured over layers of tubes, and then another layer of tubes being added and another ribbon of polymer. Heat exchanger structures so formed are also disclosed.

Abstract: A heat sink assembly includes a heat sink (40), a fan (30), and a fixing device (10). The fan has a chassis (32), and a hollow cylinder (34) extending upwardly therefrom. The heat sink has a base (42) which defines a pair of grooves (422) in a bottom surface thereof, and a plurality of fins (44) with a transverse slot (442) defined through the fins. The fixing device includes a body (12), and four resilient legs (14) depending from corners of the body. A pair of lips (22) depends from opposite edges of the body. A tab (24) extends inwardly from each lip, for engaging in the slot of the heat sink and thereby preventing the fixing device from moving laterally. A hook (18) is formed at a distal end of each leg, for engaging in the grooves and thereby attaching the fan to the heat sink.
