Wholesale Price China Hot Water Electric - Vacuum glass tube solar collector – Yuxin Detail:

Product introduction

The water-in-glass evacuated tubular solar water heater is the most widely used form of evacuated tube collector because it has higher thermal efficiency than other evacuated tube collectors employing metal-in-glass manifolds and has simpler construction requirements and lower manufacturing costs. A water-in-glass evacuated tube solar water heater typically consists of 15–40 flooded single-ended tubes in direct connection to a horizontal tank. The solar absorber tube consists of two concentric glass tubes sealed at one end with an annular vacuum space and a selective surface absorber on the outer surface (vacuum side) of the inner tube. The heat transfer in this collector is driven purely by natural circulation of water through the single-ended tubes. Water in the tubes is heated by solar radiation, rises to the storage tank and is replaced by colder water from the tank.
