Effect of the Number of Magnesium Oxide Powders on Electrical Heat Pipes

Date of release:2018-10-25 Author: Click:

The influence of the number of magnesia powder on the electric heat pipe:

Firstly, the size of the electric heat pipe is too large and its particle size is too small. Because the surface is scaly and the area per unit weight is large, it is easy to absorb moisture, which affects the life of the electric heat pipe and brings serious pollution to the filling environment.

Secondly, the number of meshes is too small and the particle size is too large. After shrinking the tube, the surface of the electric heating wire will be crushed and the life of the electric heating pipe will be affected. When filling, it is easy to cause bad phenomena such as filament deviation, disordered filament and holes in the core of the heating ring.

Low iron magnesia color

Finally, when the filling density is 2.9/cm3, the thermal conductivity of the straight-line electric heat pipe. When the bending radius of the electric heat pipe is equal to 15mm, the conductivity of the bending part of the electric heat pipe is 1/2 times of that of the straight line. Wire breakage will occur at high temperature. The remedial method is to press the bending part.
