ABSTRACT:
To connect a heat exchange arrangement (2) which moves with a movable mirror (1) in a solar heating system, in which the mirror follows the movement of the sun relative to the earth during the day, and is pivotable to a "night" position (a, FIG. 1) protected against contamination and precipitation, a flexible hose (4) is coupled to the heat exchange arrangement at one end and, at the other, is connected to a coupler element (5) which is movable radially with respect to the pivot axis about which the mirror moves. Preferably, the coupling element is attached to an elongated pivot arm (6) which forms an essentially rigid connecting pipe for the heat exchange fluid, the pivot arm (6) being movable through a limited angle (13) and carrying the coupling element (6) at its end, the coupling element moving along a radius passing through the pivot axis of the mirror, when the mirror is at least approximately in the "noon" position, or halfway through its pivoting arc. This pivoting arc of the mirror (1) will be between about 200.degree.-270.degree., in view of the "night" position. The flexible hose, preferably, is a corrugated metal hose, and stop means (10; 45, 46) are provided for flexible joints and the deflection of the elongated rigid pipe (6).
