Heat pipe vacuum tubes

Heat pipe vacuum tubes is the application to the solar industry of heat pipe, and is the key component of solar water heater, which has great significance to the efficiency and life span of solar water heaters.

Characteristic of heat pipe:

1.The only heat pipe can still at normal work for long time under -40℃~300℃.
2. Heat transfer performance is better,heat loss is lower and heated water temperature is higher.
3. Quality control in accordance with corporation standard which is established on the basis of internationalstandard
4. The product is manufactured by 14 ordinary process, nine general control processes, and 5 key controls process.
5. Having passed the quality system byISO9001
6.China spark program product .The kinds of heat pipe classified by in-service condition
