Abstract
A bi-directional pressure relief valve for a plate fin heat exchanger including an elongated heat exchanger tube having ends and a channel for the flow of a fluid from one end of the tube to the opposite end and a bi-directional reed valve positioned within the channel. The reed valve allows fluid to flow within the channel in either direction when a pressure differential across the reed valve is sufficient to urge the reed valve to an open position, thereby enabling the heat exchanger to be used independent of the direction of fluid flow through the heat exchanger.
