The heat pipe is used in solar collector,when solar energy gets to heat pipe,medium in tube vaporized at 25 degree,then conducts heat energy received to cooling end.After the process,a circulation is completed.

Product specialty:
● Apply for two layers 3.3 high boronsilion glass tube
● The two layers glass tube,with same axis is vacuumized between them,the vacuum degree can reach 5×10-2Pa.
● Coated with AL/N/AL selective absorbing coating material
● High absorbing efficiency:the vacuum magnetic-conntrol sputtering selective absorptive coatings on the heat-collecting plates has a high absorption coefficient of more than 93%,and the emission coefficient around 6%.
● Long life:the life span can rech 15 years.
● High practicability:able to endure impact of hail less than 25mm in diameter with high heat efficiency throughout the year.


Operation principle:
Comprised of heat pipe,heat-collector plate,aluminum safety-protection cap and getter,SHCMV tube has high practicability and reliability.


Technology specialty:
The tube has two technology patents in solar energy utilization.
● The first patent technology:glass-metal heat envelopment craftwork.Patent number:79149
● The second patent technology:exhausting set for SHCMV tube.Patent number:455502


Product specialty:
● High heat effectiveness:higher than normal all-glass tube by 10%;
● Heat-pipe conduction,no water inside,thus it is successfully prevented form the defects of tube blockage and low power output caused by water fouling and deposits or dust and sand;
● With small thermal capability,it can output power in 2 minutes.The highest temperature of cooling end can reaches 2500C.The average heat efficiency can still be 50% even nder-500C.
● High efficient selective absorptive coatings and vacuum heat insulation technology ensure the tube to get higher heat output in cloudy weather and in moist area,especially in winter.
● Solar collecting plate is installed and sealed inside the tube of high-quality borosilicate glass with 5×10-2Pa of vacuum,so it cannot be corroded even in moist area;
● Hot water system can endure 0.6Pa so that it can be connected to tap water tube.


Usage range:
Able to be applied to big-scale hot hot water system,desaltification of seawater,industrial desiccation,hot supplication system etc.
