ABSTRACT:
An improved end bracket is provided for a high velocity low pressure blower assembly. The end bracket includes a pair of members, each heat sink having several vanes. The bracket further includes a bearing boss having heat dissipating vanes radiating from it. The heat sink members and vanes serve to dissipate heat from a bearing which is mounted in the bearing boss. The bracket also includes a tangential exhaust horn having a threaded hose coupling. The exhaust horn communicates with a tapered scroll passage which serves to direct air to the exhaust horn. The scroll passage is tapered to allow the high velocity air to expand as it becomes hotter, thereby reducing turbulence at the exhaust.
