Abstract
A flapper valve snaps into position in an inlet or outlet manifold of a heat exchanger to provide by-pass flow in cold flow or pressure spike conditions. The flapper valve includes a cradle having opposed spring fingers for retaining the valve in position. The cradle has a fluid port therein, and a spring flapper is attached to the cradle to cover the fluid port to control the by-pass flow therethrough.
