In accordance with these improvements, one of the faces of the collecting plate is equipped with tubes for the fluid and the other with a sheet of flexible thermal insulating material. This is fastened around its edges to a border of a surrounding framework like a frame or laminated bucket that has lateral walls and, at least, bottom portions on the edge and adjacent to these lateral walls. The inner space is delimited by the insulating sheet, the lateral walls and the bottom plane, filled with a synthetic resin composition that expands in situ to form a cellular structure that is rigid, as well as being a heat insulator, and secures the elements, forming a single block panel within which the flexible insulating sheet provides the collecting plate with the necessary freedom to allow for movement due to thermal dilation and contraction.
