AT solar thermal collec 3D print model

3D model of the AT Solar Thermal Collector Type 2 features a flat plate design, encased in a vacuum box that ensures flow tubes are well-insulated. The collector rotates freely, a full 360 degrees horizontally and 90 degrees vertically, via electric motors under automated control. This comprehensive system relies on two printed circuit boards: one manages solar tracking, while the other governs cold water supply and hot water drainage. The two valves at the collector are programmable, allowing users to trap water for specified durations. Importantly, the pump and trough valves work together seamlessly; this harmony is maintained due to a movable lid that protects the non-waterproof troughs from overflow. However, a notable peculiarity arises when initial operation begins: without water within the collector itself (but present in the troughs), water cannot be pumped up by the system's pump. To resolve this challenge, the collector valves must first be closed and the flow tubes manually filled through a screwcap on the inlet pipe.
