摘要： A heat transfer tube (1) with a finned inner surface, which is divided into at least two zones (Z1 to Zm) in peripheral direction. The fins (2, 3), which extend at an angle of inclination null with respect to the longitudinal axis of the tube, are arranged in the individual zones (Z1 to Zm) in any desired periodic combination and sequence of at least two fin heights (H1 to Hn, H1>H2> . . . >Hn). Adjacent zones border thereby on one another so that the fin sequence is staggered for at least one fin in longitudinal direction of the tube. Modifications include the finned inner surface being divided into groups of zones, in which the angle of inclination of the fins is uniform, however, varies between adjacent groups.

摘要： Vibration decoupler apparatuses, for decoupling vibrations, for example, between first and second the components of an internal combustion engine exhaust system. The flexible connector apparatus is provided for connecting first and second components in the exhaust system, and includes a resilient flexible sealing member (bellows) for accommodating relative movement between the first and second components. The flexible connector apparatus includes an annular vibration damping member connecting a down pipe to a mounting member for permitting restricted axial, lateral and angular movement of the downpipe, relative to the mounting member, which may be affixed to an exhaust manifold, for example. The apparatus also includes a sealing construction which enables weldless, gasketless connection of the bellows. An alternative construction positions the vibration damping member between the decoupler apparatus and the downstream component. The damping member and the resilient flexible sealing member may additionally be axially separated.

摘要： A method includes the round billet skelping, several runs of each round billet drawing up to a given size, packing the drawn billets into a multilayer bank, corrugating the bank with the bellows formation as a result and its heat treatment. Each round billet is skelped of the age-hardenable nickel alloy containing components of the following group: niobium, aluminum, titanium, tungsten and molybdenum. Each round billet is drawn, heated up to the temperature of 1000-1130° C., held in the shielding medium at the above temperature, and cooled down, after that the above operations of drawing, heating, holding and cooling are repeated until the given size of each round billet is reached. The drawn round billets are packed into the multilayer bank and the bank is corrugated for forming the multilayer bellows. The heat treatment of the bellows is made by its heating up to the temperature of 1000-1130° C., holding in the shielding medium at this temperature until the strengthening phase is completely dissolved in the alloy and subsequent cooling down to the temperature of the phase transition termination in the alloy. A rarefied air medium or argon are used as the shielding medium.

摘要： A method for forging a die core with a given shape for manufacturing metallic hollow pipes with a thin wall, the method is completed by using a hollow can shaped plastic film loaded with a filler, the plastic film is endued with embossment in conformity with the shape of a desired shaped pipe wall; the filler can be chosen from three kinds, i.e., the liquid, plastic and heat resistant fillers, to be filled in the plastic film, an opening of the plastic film is then sealed; fast freeze the liquid filler to form a frozen die core, cool the plastic filler to form a plastic die core, or insert a heat resistant steel post in the heat resistant filler and then bake or sinter to harden it to shape the heat resistant die core for hot forging. By such method, a die core for use in cold or hot forging can be placed in a pipe hole of a metallic pipe casting, and suits die moulding by the cold or hot forging, the pipe wall of the casting thus is forged to form an embossed wall conformed in shape to the embossed plastic film, and the die core can be easily taken out of the shaped and embossed pipe after the cold or hot forging.

摘要： An evaporator heat transfer tube (10) for use in a heat exchanger where heat is transferred between a fluid flowing through the tube and a fluid flowing around the exterior of the tube and where the fluid external to the tube boils during the heat exchange process. The tube has a plurality of helical fins (20) extending around its external surface (13). A pattern of notches (30) extends at an oblique angle (.alpha.) across the fins at intervals about the circumference of the tube. A spike (22) having a flattened distal tip (23) is formed between each pair of adjacent notches. The maximum width (W.sub.t) of the spike at its tip is greater than the width (W.sub.t) of the base portion of the fin and is of a width sufficient to overlap with and contact the distal tips of spikes in adjacent fins on both sides thereof, thus forming reentrant cavities between the adjacent fins and under the overlapping tips. The fins, notches and spikes are formed in the tube by rolling the wall of the tube between a mandrel and, first, a gang of finning disks (63), then, second, a notching wheel (66) and, third, a smooth wheel (67) to flatten the spikes and create the overlapping of spike tips.

摘要： A method for making slender seamless steel mold is disclosed, wherein the outer surface of a solid slender male mold is first chased with concave and convex stripes. Then, the male mold is hardened and fitted into a hollow female mold which has not been gone through hardening process. Thereafter, a hydraulic pressure is exerted onto the outer surface of the female mold so as to impress the concave and convex of the male mold onto the inner surface of the female mold. Then the male mold is annealed and drilled with a longitudinal through hole. At least three longitudinal slits are cut on the wall of the through hole in an outward direction. Finally, the male and female molds are together heat-treated and put into water with normal temperature in order to create fissures at the slit portions of the male mold and crack the male mold into pieces. Consequently, a slender seamless steel mold having inner surface formed with concave and convex stripes is completely made.
