Abstract: This work presents the design of a double pass solar air heater fixed on the wall by a four legs design pivoting system. In the case of supplying a building with hot air, for heating purposes, or for industrial applications such as drying or preheating, this pivoting mechanism consists of two supports with two legs linked to the collector itself and the fixing is ensured by two clevises. To make a static simulation of the pivoting mechanism, we use the CAD software Solid Works. According to the obtained results, we can approve that our support can bear the load of the solar collector and resist to weather conditions.

Key words: Double pass solar air heater, four legs design pivoting system, static simulation, Solidworks.
