AT solar thermal collec 3D print model

3D model of the AT solar thermal collector type 2. The Type 2 is a flat plate collector. It has a vacuum box so as to provide insulation of the flow tubes. The collector can be rotated 360 degrees horizontally, and 90 degrees vertically, by means of electric motors. The entire system is automated, the automated system uses 2 printed circuit boards; 1 for the solar tracking, another for the control of the cold water supply/ hot water draining. The 2 valves at the collector are settable to allow the trapping of the water for a specific duration. Note that the pump and trough valves are set to work together flawlessly; this due to the movable lid of the troughs; the troughs are not waterproof and cannot be allowed to fill up entirely. In the beginning, when there is no water in the collector itself (only in the troughs), the water cannot be pumped up by the pump; to solve this problem, the collector valves need to be closed and the flow tubes need to be manually filled first, by means of the screwcap on the inlet pipe.
