Abstract
A heat pipe heat transfer structure for use in a furnace wherein individual heat pipes are arranged in a series for successive heat transfer association with the hot products of combustion of the furnace. The heat transfer enclosure defines successively a combustion chamber portion, an acoustic decoupling portion, and an input heat transfer chamber portion. The heat transfer chamber portion, in turn, is divided into first and second portions. The first portion of the input heat transfer chamber portion, in the illustrated embodiment, decreases in cross sectional area in a direction away from the burner. The final portion of the input heat transfer chamber portion, in the illustrated embodiment, has a constant cross sectional area. The heat pipes are arranged in a folded series row, with the direction of the products of combustion being reversed in entering the first portion from the combustion chamber and in passing from the first portion to the second portion before being discharged to the vent pipe of the furnace. The construction provides improved uniform loading of the heat pipes and acoustic decoupling of the burner from the input heat transfer chamber portion.
