Patent number: 6066043Abstract: Disclosed is an apparatus and method to redirect airflow and enhance heat transfer using an oscillating baffle. This apparatus and method allows for the improved efficiency of a heat transfer tunnel, while reducing the size of the tunnel. Several embodiments of the oscillating baffle have a first degree of freedom and a second degree of freedom which allows it to oscillate under the power of the airflow. The method employs the oscillating baffle to redirect and mix the airflow in order to enhance heat transfer in a heat transfer tunnel. The oscillating baffle is used for cooling, for heating, for enhancing the mixing of a multi-component air flow or redirecting an air flow. Other applications could include use in dusty environments to provide high speed gas streams sweeping a wall to prevent the build-up of dust.Type: GrantFiled: December 8, 1997Date of Patent: May 23, 2000Inventor: Charles W.

Patent number: 5906862Abstract: A method and apparatus for coating and drying coated substrates without introducing significant surface imperfections while running at higher web speeds than known drying methods. The substrate is preferably coated within the drying enclosure or the coating bead may form a closure at the entrance of the drying enclosure. The substrate is moved through a first drying enclosure along a first axis. The first drying enclosure is substantially isolated from an external environment. A first low velocity, substantially laminar flow field of a drying gas is directed across the front surface of the substrate. The first flow field is generally parallel to the front surface and generally perpendicular to the first axis to minimize the formation of surface imperfections during the evaporation of the coating solvent. The substrate may then be moved to subsequent drying enclosures through transition enclosures that minimize surface imperfections due to high velocity interaction between the adjacent drying enclosures.Type: GrantFiled: April 2, 1997Date of Patent: May 25, 1999Assignee: Minnesota Mining and Manufacturing CompanyInventors: Robert A.

Patent number: 5548907Abstract: Several methods and apparatus for transferring heat, mass and momentum between a fluid and a surface are disclosed wherein the fluid is separated into a multiplicity of tiny jets that impinge upon a surface to be treated and flow across it for very short distances before reforming jets that leave the surface. While in contact with the surface, the fluid flow is laminar and the boundary layer that resists transfer of heat, mass and momentum is extremely thin. Hence, heat, mass and momentum transfer coefficients are large and predictable from first principles of physics. The pressure drop and fan power required to form these jets are generally less than that required to drive the flow parallel to the surface for long distances, where the boundary layer grows much thicker.Type: GrantFiled: August 30, 1993Date of Patent: August 27, 1996Assignee: Energy Innovations, Inc.Inventor: Meredith C.
