MGV heat pipe tube solar collector
1. Perfect reliability
2. Long services-life, over 20 years
3. Low spec

  MGV heat pipe tube solar collector  

 

φ70mm MGV Heat Pipe Tube is one of the core technologies of JIADELE , it’s more suitable for middle temperature applications. It has a bigger absorber area with characteristics of strong resistance of very low temperature, better thermal performance, higher operating temperature and wide range of applications.

 

Features

1. Perfect reliability

2. Long services-life, over 20 years

3. Low specific heat capacity, fast start up

4. Easy installation, convenient maintenance

5. High heat efficiency, higher than that of normal vacuum tube

6. No water flows inside the tube, anti-scaling, preventing tube from frozen to crack in extreme cold environment (-50°C)

7. High vacuum grade (10-8 bar) guarantees high efficiency even in cloudy day, cold environment and high-temperature application

Details:

TM70 Tube (70mm Super Heat Conduction Metal-Glass Vacuum Tube)

This is FULL-VACUUM Tube with Heat-Pipe. The absorber plate catches the sunshine and transfer the heat to the heat-pipe DIRECTLY. Then the heat-pipe transfers the heat to the condenser above, where heat exchange is made with the water in the collector. The system is easy to install. No water flows inside the tube, which makes the system remains workable if one tube breaks.
