Problems solved by technology

[0009] In this regard, it is easy to think of inserting a stainless steel heat pipe containing a heat medium into the above-mentioned oblique hole, that is, the intubation technique, but the intubation technique always requires dozens of deep holes to be drilled upwards on the upper circumference of the roller body, which is difficult to process The production efficiency is low; moreover, the intubation on the heat roller body is carried out separately, and the heat pipes cannot be communicated with each other, which affects the heat transfer effect and the dynamic balance adjustment of the heat roller

Abstract

The invention provides a heat pipe assembly. The heat pipe assembly comprises a combined heat pipe and a heat ring communicated with the combined heat pipe; the combined heat pipe comprises a plurality of heat pipes arranged in the axial direction, and each heat pipe is an inclined pipe. The combined heat pipe type hot roller has the advantages of being high in heat transfer efficiency, small in resistance loss, compact in structure, convenient to machine, reliable in work and low in maintenance cost, the temperature uniformity of the roller body of the hot roller is improved, the machining difficulty and cost are reduced, the dynamic balance of a heating medium in the hot roller is reduced, and heating medium steam in the heat pipe is better diffused and distributed.

Description

technical field [0001] The invention relates to the technical field of heat rollers for chemical fiber drafting, in particular to a heat pipe assembly, a combined heat pipe type heat roller including the heat pipe assembly and a processing method thereof. Background technique [0002] In the heat treatment process of synthetic fibers, the induction heating roller is an ideal heating roller form. Further, in order to improve the uniformity of temperature distribution on the surface of the roller, heat pipe technology is adopted. [0003] For the magnetic steel roll body, the heat source of the induction heating roll is the roll itself, or for the aluminum alloy roll body, its inner wall will be closely connected with a circle of high magnetic steel sleeve structure for induction heating, all of which are direct heating. The heating method, its temperature controllability and responsiveness are better than any other indirect heating roller. The induction coil that generates t...
