Three, utility model content
The purpose of this utility model is heat insulation in order to solve existing vacuum glass heat collection tube individual layer, and water circulates slowly, and it is unbalanced to be heated, and firing rate is slow, thereby a kind of new technical scheme is provided.
For achieving the above object, the utility model can be realized by following scheme: straight-through thermal-collecting tube of a kind of double thermal insulation and module units thereof, thermal-collecting tube is made up of concentric outer layer glass tube and straight-through inner layer glass tube, be vacuum between outer layer glass tube and the straight-through inner layer glass tube, thermal-collecting tube leads directly in the two ends; Be provided with metal tube in straight-through inner layer glass tube, affiliated metal tube two ends are conical pipes, and the metal tube two ends plug by rubber seal and isocon and collecting pipe; Be fixed with metal tab in the corresponding both sides of metal tube; Isocon and collecting pipe are provided with insulation material.
The cross sectional shape of thermal-collecting tube is flat or ellipse.The metal tab that the corresponding both sides of metal tube are fixed with it be shaped as corrugated.
The advantage that the utility model had is: simple in structure, with low cost, in light weight, easy to install.Double thermal insulation leads directly to thermal-collecting tube, is in straight-through vacuum double glass tube metal tube to be housed, and forms an air chamber between straight-through inner layer glass tube and metal tube.Be fixed with the ripple type metal tab in the corresponding both sides of metal tube, water just flows in metal tube.Metal tab has increased collector area again simultaneously, improves the programming rate of water, because water flow faster in thermal-collecting tube is less scaling in metal tube.The set metal tab in metal tube both sides is increasing the supporting role of having played again when solar energy utilizes area in air chamber metal tube.The metal tube of the band metal tab that in thermal-collecting tube, is provided with and the air chamber that increases alleviates the overall weight of thermal-collecting tube, and it is reduced installation requirement and manufacture difficulty, production cost descends.
The effect of ripple type metal tab: one, utilize the elasticity of corrugated metal tab itself that metal tube is supported in the thermal-collecting tube, can make thermal-collecting tube bear extraneous powerful vibrations.Two, increase collector area, improve the solar energy utilization ratio; Three, the corrugated metal tab of prolonging metal pipe range trend can make thermal-collecting tube wideer to the accommodation of sunlit angle.
