Cause analysis and solution of tube explosion of condensing vacuum tube

The condensing vacuum tube explodes frequently. Through investigation and experimental analysis, due to the heat accumulation in the vacuum tube and the disorder of the heat flow field, effective convective heat transfer cannot be formed, and the internal pressure of the vacuum tube increases, resulting in tube explosion. By changing the internal structure of the vacuum tube to solve the problem of tube explosion, the experiment shows that increasing the diameter of the inner tube of the vacuum tube, adding a guide tube in the vacuum tube, adding a small glass tube in the vacuum tube, and the integrated all-glass vacuum collector tube structure can solve the problem of tube explosion.
