摘要： A modified cross-section material having a thin part and a thick part in its widthwise direction is manufactured through a plurality of roll stages. Each rolling stage comprises of a set of a convex roll and a flat roll, wherein the convex roll has a convex part. The thin part is formed in accordance with the lengthwise expansion by the convex part of the convex roll, and the thick part is formed in accordance with the lengthwise expansion by a part other than the convex part of the convex roll.

摘要： A method for producing a strip of material having a non-uniform cross section is carried out by passing a strip of material in the longitudinal direction through a first set of working rolls, at least one of which is provided with an annular slot intermediate the ends thereof so that a reducing force is applied only to those portions of the strip engaging said roll on opposite sides of the slot whereby the excess material flows toward that portion of the strip opposed to the slot to cause the strip to buckle outwardly into the slot. The strip is subsequently passed through a set of smooth rolls to flatten the buckled portion. This procedure is repeated any desired number of times with the width of the slot becoming progressively smaller. The strip may then be passed through one or more sets of finishing rolls and a heating and annealing operation can take place before each passage through a set of finishing rolls.
摘要翻译：用于制造具有不均匀横截面的材料条的方法通过使材料条沿纵向通过第一组工作辊来进行，第一组工作辊中的至少一个设置有在端部使得减小力仅施加到在槽的相对侧上接合所述辊的条带的那些部分，由此多余的材料朝向与槽相对的条带的部分流动，以使带条向外弯曲到槽中。随后将条带通过一组光滑的辊以平坦化带扣部分。该过程重复任何期望的次数，槽的宽度逐渐变小。然后可以将带材通过一组或多组精加工辊，并且可以在每次通过一组精轧辊之前进行加热和退火操作。

摘要： In a heat transfer tube for a zeotropic refrigerant mixture, the inner surface of the tube in which the zeotropic refrigerant mixture flows is formed with grooves having cross portions where the grooves intersect with each other, or the inner surface of the tube is formed with a plurality of independent projections. Thus, concentration boundary layers generated in the zeotropic refrigerant mixture are stirred to reduce the thickness of the concentration boundary layers, thereby decreasing the diffusion resistance and promoting the stirring effect. Consequently, there can be provided a heat transfer tube for a zeotropic refrigerant mixture which exhibits a high heat transfer performance, and a heat exchanger of a cross-fin tube type, a refrigerator and an air conditioner which include such heat transfer tubes.
