SHCMV tube is mainly assembled with heat-pipe, borosilicate glass tube, heat-collecting plates, metal cover, getter, heat exchanging end and aluminum safety-protection cap, etc. the magnetic-control sputtering selective absorptive coatings on the heat-collecting plates has a high absorption coefficient of more than 94%, and the emission coefficient around 8%. The vacuum degree in the borosilicate glass tube is more than 5x10-3Pa, equipped with long effective air degassers to keep the setting vacuum degree inside the tube a constant.
