摘要： A method of forming a tube joint which can be used in a desalination plant includes providing a fluted tube, applying a sealant to the tube end and inserting the tube end into a tube sheet or plate to form a joint therebetween. After insertion, the inner surface of the fluted tube is worked to deform external ridges of the fluted tube and uniformly distribute the sealant throughout the joint area. The fluted tube is deformed using a roll expanding method. The fluted design of the tube retains sealant in the joint area during tube insertion and expansion and takes advantage of the heat transfer characteristic of the flutes to provide an improved joint construction especially adapted for heat exchange use.

摘要： A method for producing corrugated tubes of substantially high surface area for use in tube-in-shell heat exchangers which are particularly efficient for cooling water involves pointing a heat exchange tube at both ends to reduce the diameter substantially and increase the wall thickness of the pointed ends and then corrugating the tubes linearly. The tubes each having intermediate portions linearly corrugated to provide equally spaced deep corrugations extending in a straight line parallel to the axis of the tubes. The corrugations, which are equivalent to tubes, multiply the amount of heat transfer attainable from the point diameter selected for attachment to the tube sheets. The ratio of the surface area of the corrugated body portion to the surface areas of said reduced ends, per unit length, is in the range from about 1.5:1 to about 4:1. It also makes possible the contiguous relation of each tube to the surrounding tubes. The nesting of the tubes in a heat exchanger minimizes by-pass of the fluid and controls the velocity essential to achieving turbulent flow and attendant high rates of heat transfer.

摘要： A heat transfer assembly is provided having heat transfer elements which contact end portions of a pressure roller of a fuser assembly. A heat transfer fluid is caused to pass over the elements in response to a signal to remove heat therefrom thereby cooling such portions of the pressure roller in contact with the elements.

摘要： The single tube or single tube of a three, five or the like uneven number of tubes extending between a header unit attached to the underside of a boat hull in communication with the water circulating pump of the inboard engine and a return fitting attached to the underside of the hull is centrally divided into side-by-side separate compartments of equal area and volume by a longitudinally extending flat divider plate so that the uneven number of tubes is converted into an even flow number whereby an accurate volume flow can be achieved between the header and the return fitting in terms of the volume capacity of the water circulating pump.

摘要： An inner pipe (2) is designed for a heat-transferring double pipe that exchanges heat between a fluid that flows through the interior of the inner pipe and a fluid that flows between the inner pipe and an outer pipe (10) that surrounds the inner pipe. The inner pipe has a first region (21) and a second region (22), which have transverse cross-sectional shapes that differ. The first region has a plurality of first protruding parts (211) that protrude outward and form a first recess-protrusion shape in which locations of the first protruding parts are offset helically in a longitudinal direction. The second region has a plurality of second protruding parts (221) that protrude outward and form a second recess-protrusion shape, in which locations of the second protruding parts are offset helically in the longitudinal direction. The number of second protruding parts is greater than the number of first protruding parts.
