Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thus provides the metal fever tubular type that a kind of structure is simple, reliable and stable and Heat-collecting effect is well easy to use flat-plate solar heat collector.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of metal fever tubular type flat-plate solar heat collector, comprise by thermal-collecting tube, the heat-absorbing plate core that forms with multiple metal heat pipe of described thermal-collecting tube grafting and absorber plate, the corresponding described metal heat pipe of described thermal-collecting tube is respectively arranged with bell-and-spigot pipe, thermal-collecting tube described in described bell-and-spigot pipe lateral penetration; Described metal heat pipe closed at both ends, comprises evaporator section and condensation segment, and the length of described condensation segment and the length of described bell-and-spigot pipe adapt and is socketed in described bell-and-spigot pipe, and described evaporator section fits on described absorber plate.
Based on above-mentioned, the inserting hole of the corresponding described bell-and-spigot pipe of described thermal-collecting tube is the hole punching with flange, and the height of described flange is 1-2mm, and described bell-and-spigot pipe and described thermal-collecting tube are by described flange brazing.
Based on above-mentioned, described evaporator section laser weld is on described absorber plate.
Based on above-mentioned, the latus rectum of described condensation segment is greater than the latus rectum of described evaporator section.
Based on above-mentioned, outside the tube wall of described condensation segment, be coated with heat conductive silica gel.
Based on above-mentioned, in described metal heat pipe, be filled with heat conduction with phase change working medium.
The utility model hinge structure has substantive distinguishing features and progress, and specifically, the utility model utilizes the metal heat pipe grafting of thermal-collecting tube and closed at both ends, adopt the mode thermal-arrest of heat exchange, described metal heat pipe is closed system, there is not contaminant problem, thermal starting is fast, and heat transfer rapidly.Furtherly, described metal heat pipe closed at both ends is not connected with described thermal-collecting tube, avoids both to be communicated with welding existing defects, causes heat collector to be scrapped; If a wherein metal heat pipe breakage, can not affect other metal heat pipes and work on, and runner can not be affected normally work, improve stability of the present utility model.A step is said again, and because taking the thermal-arrest mode of heat exchange, do not need in described metal heat pipe to add anti-icing fluid, the anti-icing fluid consumption of heat collector greatly reduces, and reduces cost.The utility model has the advantage that structure is simple, collecting efficiency is high and stability is high.
