Structures: top cover, bottom cover, central watering copper tube, sheath, left and right close cover, seal and rockwool heat insulation material, etc.

Operating principle: the condensation end of the super conducting vacuum tube transform the heat to the sheath, the sheath doesn?t flow water, the water is introduced by ф22 cooper tube, the water contacts sheath for heat exchange, the heat cycle is repeated, the water in tube become hot rapidly, then the hot water is out, thus the super conducting vacuum tube application in heat collection system is achieved, that is a breakdown in super conducting vacuum tube application, the function index has already passed U.S.A SICC certification and Switzerland SPF certification. The TJ sheath and water tank are welded together through rigid connection, the test pressure reached 11Kg/cm2, there is no water leakage danger, the out cover of collecting box applies stainless steel or fluorine and carbon sprayed aluminum sheet for a eternal well performance, plus the special design makes an easy assembly and makes the product more suitable to the house; the unique structural design helps the solar system work with high efficiency and it is the best choice for solar heater. During the operation of the system, although there may be one or several vacuum tubes break, it will not damage the operation of the entire system.
