从China供应商批发进口15 Tubes Heat Pipe Solar Collector — FOB条款

Key points High performance evacuated tube collectors Can be mounted free-standing or on a pitched roof, easy to install, simple roof fixings Heat pipe - offer low maintenance No water in the vacuum tubes, no freezing problem in winter, can be used in cold area. One broken tube will not affect the function of the system. 3 years warranty, 20+ years lifespan Market leading efficiency/output Triple layer selective absorber coating, absorption coefficient 94% Evacuated tube outer tube thickness 1.8mm 14mm high conductivity heat pipe condenser, Nick-coated condenser surface. Aluminum frame, strong structure, light weight. High and constant pressure of polyurethane foaming technology ensure the outstanding insulation quality. 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.
