Wind tunnel turning vane heat exchanger

A wind tunnel turning vane heat exchanger in a recirculating wind tunnel comprising:

• a rack;
• a plurality of hollow turning vanes formed to allow a fluid to flow through a hollow area of the turning vanes, said hollow turning vanes mounted on the rack and disposed substantially parallel to each other across a plenum of the recirculating wind tunnel;
• each turning vane having a body extending between two ends, the body having an exterior surface, the exterior surface forming a perimeter;
• connection pieces at each end of the hollow turning vanes to connect the turning vanes to a fluid pipe system;
• and
• said connection pieces being formed of a single piece and formed to allow a fluid to flow from the hollow area of the turning vanes through the connection pieces, said connection pieces connecting in a fluid tight manner to the hollow turning vanes without heat or chemical bonding;
• wherein the turning vanes have internal cross bracing within the hollow area thereof and the connection pieces connect to the internal cross bracing with a removable mechanical connector
• wherein the connection pieces connect to the turning vane at corresponding connection points on the ends of the turning vanes and the connection pieces, all of the connecting points being within the perimeter of the turning vane.
