Heat pipe solar collector working principle: The heat pipe solar collector always connected with existing water heating device. The selective absorber coating on the inner cover of vacuum tubes absorb solar energy, then convert solar energy into thermal energy and transfer thermal energy to heat pipe by aluminum fin.
Principle:
Evacuated tube solar collector use evacuated tubes to absorb solar energy then transfer energy to heat pipe via aluminum fin, when heat pipe is heated and working liquid vaporize and rise to top of heat pipe condenser (condenser is inserted into the mainfold port inside the solar collector manifold), when the heat pipe condenser meet cold water flow inside the manifold port, the working liquid will cool down and fluidify return to the bottom of heat pipe, so time and time again repeat this process, finally cold water(glycol) inside the manifold port be heated.

Before installation, please note:
1. Installation personnel must wear gloves, avoiding to scratch hands due to glass tubes broken during the installation.
2. When touching the condenser and collector’s pipe head of heat pipe during installation, should pay attention to scald.
3. If collector is installed on the simple roof, collector’ weight to the effect of roof capacity should be considered.
4. When installing the collector, please take into consideration the issue of wind and snow loading. High wind and snow regions may require inspection and approval by an authorized engineer or the local building department. It is the responsibility of the installation officer to ensure that the frame mounting is of suitable strength points.
5. To have the best performance, please make sure the installation angle at 15-75 degree.
