Abstract：

In　this　paper　the　mathematical　model　of　all-glass　vacuum　tube　collector　unit　used　in　passive　solar　heating　system　have　been　established　and　verified　through　multiple　experiments　(different　connections,　different　flow,　different　weather　conditions).　Experiments　showed　that　the　model　had　accurate　described　the　heat　transfer　processes　of　all-glass　vacuum　collector.　Compared　to　the　empirical　formula,　the　model　is　simpler　and　has　a　higher　precision.
