What Is a Microheater?
A microheater is a heater that can deliver indirect heating by wrapping it around a metal or other surface without gaps.
Temperature rise is fast and thermal efficiency is high, making it possible to heat efficiently. The sheath and heating element are flexible and can be easily bent, rolled, or deformed. Therefore, microheaters can adapt to their intended application. The sheath is made of stainless steel or other materials that are highly heat- and corrosion-resistant.
Uses of Microheaters
Microheaters are lightweight and very thin. They are highly flexible and can deliver uniform heating over a wide area of any length. They are used in a variety of locations, mainly for indirect heating purposes.
Microheaters are widely used in experimental and industrial fields. They are used to retain heat to prevent pipes and other elements from freezing, and for heating and retaining heat between metal plates.
When using microheaters, space them a certain distance apart so that they do not overlap, and wrap them tightly and securely around the object to eliminate any gaps. They can be bent by hand without the use of tools, making them very easy to use.
Structure of Microheater
The part of a microheater that generates heat is a thin metal tube that encloses an insulator surrounding the heating wire. Since the heating wire does not come into contact with gas, the effect of deterioration due to oxidation, etc. is minimized, and the heater can be used for a long period of time.
The heat-generating part is cut to the required length, and an adapter and lead wires are added externally to both ends of the part. Moisture-proofing is applied around the lead wires to prevent corrosion due to humidity.
The reason for the fast temperature rise and high thermal efficiency is the small tube, which can hold a small amount of heat and easily transfer heat to the outside.
