Abstract

The invention discloses an intensified convection heat exchange solar heat collector header. The intensified convection heat exchange solar heat collector header comprises a header shell, a heat preservation layer, vacuum pipe connecting holes, a header inner container, a separation plate, a rotating impeller, an impeller connecting rod, a medium outlet pipe and a medium inlet pipe; the header inner container is located in the header shell, the position between the header shell and the header inner container is filled with the heat preservation layer, the multiple vacuum pipe connecting holes are formed in the side face of the solar heat collector header, the rotating impeller is arranged in the header inner container, and is coaxially and fixedly connected with the impeller connecting rod, and the impeller connecting rod can be selectively connected with a wind impeller or a motor box connected with a photovoltaic cell panel; the solar heat collector header intensifies convection heat exchange of a solar heat collection device through new resources of wind or solar energy, the solar utilization rate is improved, and meanwhile the header is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a solar collector header, in particular to a solar collector header which utilizes new energy to strengthen convection heat exchange, and belongs to the technical field of solar heat collection. Background technique [0002] As a clean, non-polluting renewable energy, the development and utilization of solar energy is regarded as an important part of the world's energy strategy. Solar water heaters have been successfully commercialized, and how to use solar energy more effectively has become the research content of scientists from all over the world. [0003] The solar vacuum tube collector is currently the main form of solar heat collector for low-temperature solar heat utilization. The solar vacuum tube collector needs a header to connect multiple vacuum tubes into one. The header is an important part of the solar vacuum tube collector. The performance directly affects the effect of solar energy harvesting. [0004] At pres...
