PURPOSE: A screw joining-type solar heat collection device is provided such that certain sealing and insulation are guaranteed as a sealing packing wraps a binding pipe in the process of attaching a heat collection pipe. CONSTITUTION: A screw joining-type solar heat collection device comprises a heat collection box(100), vacuum heat collection tubes(200), and a heat collection pipe(300). The vacuum heat collection tubes are attached or separated from the lower part of the heat collection box at regular intervals. The heat collection pipe is sealed in the vacuum heat collection tube. The combining pipes(110) protrude from the lower part of the heat collection box, and screwed to the heat collection pipe. The thread joining part(310) of the heat collection pipe is connected to the opening(210) of the vacuum heat collection tube through a sealing packing(610). The sealing packing wraps the combining pipe to increase the sealing and insulating effect. |
