Abstract
As shown in the diagram, a controllable heat transfer channel is arranged between a vacuum heat collecting element absorber 1 and a cover glass pipe 2, wherein the controllable heat transfer channel is formed by movable heat transfer elements 3 and a thermal transduction double-sheet metallic driving element 4 connected with the vacuum heat collecting element absorber 1 under low heat resistance. The thermal transduction driving element does work by means of heat energy and comprises double metallic sheets, a memory alloy and a capsule (also called as an elastic element) driving element. The two ends of the driving element 4 are connected with two L-shaped movable heat transfer elements 3. The driving element 4 can be fixed to the absorber 1 through metal wires. After passing through the cover glass pipe 2, the sunlight is irradiated on the absorber 1 so as to be changed into heat energy. During normal heat collecting and stagnation protection, the states of the driving element 4 and the movable heat transfer elements 3 are represented as dotted lines / solid lines, wherein the driving element 4 is in a curved / straight state so as to enable the movable heat transfer elements 3 to break away from / be in contact with the cover glass pipe 2. Meanwhile, a high / low heat resistance state is formed between the absorber 1 and the cover glass pipe 2.
