Explosion-proof heating tube

Abstract

The invention discloses an explosion-proof heating tube, which comprises an integrated box, a heating mechanism, an explosion-proof tube sleeve and cooling fins. The heating mechanism is arranged on the integrated box, threads are arranged on the periphery of the heating mechanism, and corresponding threads are arranged on the inner periphery of the explosion-proof tube sleeve, with the heating mechanism and the explosion-proof tube sleeve being connected to each other in a manner of thread fit; the explosion-proof tube sleeve is made of metal heat conduction materials, and the length of the explosion-proof tube sleeve is smaller than the length of the heating mechanism; a plurality of cooling fins are arranged on the periphery of the anti-explosion tube sleeve in parallel, and the coolingfins are obliquely arranged. The anti-explosion device has a good anti-explosion effect and prevents equipment from deforming in the using process, the heating efficiency of equipment is improved, and the heating effect is guaranteed.

Description

technical field [0001] The invention relates to the field of heating pipes, in particular to an explosion-proof heating pipe. Background technique [0002] Electric heater is an internationally popular high-quality and long-life electric heating equipment. It is used for heating, heat preservation and heating of flowing liquid and gaseous medium. When the heating medium passes through the heating chamber of the electric heater under pressure, the principle of fluid thermodynamics is used to uniformly take away the huge heat generated by the electric heating element during work, so that the temperature of the heated medium meets the user's process requirements. [0003] In the prior art, the electric heating element in the electric heating tube generates high-temperature heat energy, which increases the temperature of the heated medium and obtains the high-temperature medium required by the process; the heating tube has the problems of slow heating efficiency and low heat ex...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the electric heating element in the electric heating tube generates high-temperature heat energy, which increases the temperature of the heated medium and obtains the high-temperature medium required by the process; the heating tube has the problems of slow heating efficiency and low heat exchange efficiency during use, and the large Most of the heating tubes are basically single-layer. Repeated heating and cooling during the use of the heating tube will cause the heating tube to bend and deform, resulting in changes in the mechanical parameters of the electric heating, which cannot meet some demanding applications and not only affect the electric heating. service life, but also affect the heating effect of electric heating
