Description
Technical field
The utility model relates to a kind of vacuum solar thermal collector, belongs to the solar energy utilization technique field, and it comprises: the full glass solar thermal-collecting tube is used to receive solar radiation and obtains heat energy; U type adjuster is positioned at described full glass solar heat collection pipe, and the tube head of this U type adjuster leans out described full-glass solar energy heat collector.
Background technology
The vacuum tube type solar energy heat collector is the device of accepting solar radiation and transmit heat to heat transferring medium in solar thermal collection system, the heat-conduction principle of most of vacuum tube type solar energy heat collector in the market is that complete glass vacuum sun thermal-collecting tube is given the aluminium conducting strip with the thermal energy conduction that obtains, conduct to U type adjuster by the tubular aluminum conducting strip again, wherein the aluminium conducting strip claims the aluminium wing again, in use also plays the effect of supporting described U type adjuster in described all glass vacuum heat collection tube of solar energy.But there is following problem in this heat exchange pattern: aluminium conducting strip and complete glass vacuum sun thermal-collecting tube fit clearance are big, the binding face poor continuity; And aluminium conducting strip thickness is little, and mechanical strength is low, and the linearity of U type pipe is poor, causes both fit clearances big, in addition because above-mentioned binding face poor continuity is deviate from U type pipe easily.These factors have a strong impact on heat conduction efficiency, cause the efficient of existing vacuum solar collector on the low side.Thereby the day of causing full glass vacuum tube type solar heat collector is useful that heat is lower than common direct insertion water heater.
Summary of the invention
The utility model is at the above-mentioned defective of present vacuum solar thermal collector, the vacuum solar collector that provide a kind of collecting efficiency height, is easy to assemble.
The technical solution adopted in the utility model is:
The utility model vacuum solar collector comprises:
The full glass solar thermal-collecting tube is used to receive solar radiation and obtains heat energy;
U type adjuster is positioned at described full glass solar heat collection pipe, and the tube head of this U type adjuster leans out described full-glass solar energy heat collector;
The fit clearance of described U type adjuster and described full glass solar thermal-collecting tube is the heat conduction packed layer.
Adopted novel heat transfer structure based on the technical solutions of the utility model vacuum solar collector, just utilize the heat conduction packed layer to substitute the existing aluminium wing, make the heat transfer structure of existing line contact, become the heat transfer structure of face contact, heat transfer efficiency improves greatly.And the aluminium wing has certain structure curvature, heat conduction distance, and the heat of this programme conduction distance is short, can further improve heat transfer efficiency.
On the other hand, cooperate based on being the face contact between the member that matches of the vacuum solar collector of this programme or part, cooperate stablely, and this fit system also is easy to assembling.And the said structure good stability can not cause coming off of structure dislocation or some members in installation, transportation.
