摘要： A method of producing a heat transfer wall, including a plurality of minute tunnels parallelly extending and spaced a minuscule distance from each other under an outer surface of the wall in contact with liquid, and a plurality of tiny hole portions formed at the outer surface of the wall above the tunnels and located at regular intervals along the tunnels to maintain same in communication with the outside. Each hole portion includes a projection located in the hole portion including a hole itself and extending from the vicinity of the hole portion into the hole portion in a manner to traverse same, so that a flow of liquid into the tunnels and a flow of vapor out of the tunnels can be optimally regulated by the projections to enable the heat transfer wall to exhibit a high heat transfer performance.

摘要： A heat transfer tube has at least a row of projections provided on its inner surface at regular intervals along a spiral curve thereof. The row of projections are formed by plastic deformation of part of the heat transfer tube, which is effected by pressing a rolling disc having projections against the outer surface of the heat transfer tube. The projections have smooth curved surfaces. The height of the projections ranges from 0.45 mm to 0.6 mm, their pitch along the spiral curve ranges from 3.5 mm to 5 mm, and their pitch in the axial direction ranges from 5 mm to 9 mm.

摘要： In a heat transfer surface having cavity groups and restricted opening groups in an outer surface region, the cavity groups are composed of a plurality of rows of void strip members. The cavity strip members are arranged in parallel on a base member of the heat transfer surface and are laminated in one or more layers. Each strip member has a number of elongate cavities laterally arranged in parallel. The elongate cavities are closed at upper surfaces and have at both ends openings. The adjacent cavities in the same layer are communicated with each other by communicating portions each provided between the cavity strip members and by the openings. The restricted opening groups are formed on the upper surfaces of the communicating portions. The restricted opening groups render the communicating portions in one layer, the communicating portions in another layer and the outside to communicate with each another. The method of manufacturing such a heat transfer surface is also disclosed.

摘要： A heat-transfer wall kept at a low temperature so that hot vapor brought into contact with its surface condenses thereon. The surface is grooved at a fine pitch, having thin and sharply tapering ridges in between, with shallower fine-pitch grooves or notches formed in the ridges. The wall may be that of a tube, the grooves may consist of a continuous root in the form of a helix, and the ridges may be bent into the grooves to form rounded crests. The wall contour is made by forming fine-pitch shallow grooves crosswise by knurling and then forming fine-pitch deep grooves by cutting and turning up the surfaces in a plowing manner, for example on a lathe. A grooved die may be used to deform and bend the edges of the ridges toward the deep grooves.
