Patent number: 8298493Abstract: The heat exchange apparatus provides a flow passage for the heat exchange fluid comprising a succession of flow passage chamber portions separated from one another by intervening throttle forming passage portions of smaller cross section, and therefore of smaller flow capacity, transverse to the flow direction, so that the heat exchange fluid moves at a higher velocity in the throttle forming portions than in the chamber portions. The fluid is moved at a rate such that its velocity in the throttle forming portions is high enough to reduce the thickness of the fluid boundary layer on the passage wall and thereby facilitate the heat exchange. Alternatively, or in addition, the velocity is high enough to at least reduce the rate of fouling of the passage wall surface. Alternatively, or in addition, the fluid flows as eddy vortices, the spacing of the chamber portions along the passage being such that wake interference flow is established which enhances the rate of heat exchange.Type: GrantFiled: December 17, 2010Date of Patent: October 30, 2012Inventor: Richard A.
