A plurality of thermoplastic sheets of film are heat sealed to form complementary first and second heat transfer chambers for a pressurized fluid that is supplied to one of the chambers and which flows to the other of the chambers through an opening in the film intermediate the chambers. The film exposed to sunlight is transparent permitting solar energy to impinge upon a film disposed within the chambers for heating the chambers. Fluid ducts are connected to the apparatus for supplying the fluid under pressure to one of the chambers and for receiving the heated fluid from the other of the chambers.

DETAILED DESCRIPTION What is claimed is: 1.
A solar energy heat transfer apparatus comprising: first and second thermally insulated fluid chambers formed of pliable sheet material, said chambers having a common wall, said common wall having a solar energy absorbent surface, said chambers having a first deflated, relaxed condition in the absence of pressurized fluid therein and a second inflated condition in the presence of pressurized fluid therein, said common wall having an opening for providing fluid communication between said chambers, one of said chambers having a fluid inlet port for receiving pressurized fluid to be heated, the other of said chambers having a fluid discharge port, said ports and said opening being spaced such that said fluid passes over said common wall in said first and second chambers in flowing from said inlet to said discharge ports, one of said chambers having a light transparent outer wall.
2.
The apparatus of claim 1 further including third and fourth chambers each having an outer wall formed of pliable sheet material, said first and third chambers having a common wall therebetween, said third and fourth chambers including aperture means for receiving pressurized fluid for placing said third and fourth chambers in an inflated condition whereby said third and fourth chambers provide thermal insulation for said first and second chambers, respectively.
3.
The apparatus of claim 1 wherein said first and second chambers are formed as tubular conduits disposed in complementary arrangement about said common wall, said common wall opening being disposed at one end of said conduits, said ports being disposed at the other end.
4.
The apparatus of claim 3 wherein said common wall is disposed common to said inlet and outlet ports.
5.
The apparatus of claim 1 including a plurality of said first and second chambers placed side-by-side in a parallel array, said first chamber being disposed above said second chamber, said common wall being formed of a first sheet of thermoplastic film extending through all said first and second chambers, the outer walls of said first chambers being formed of a second sheet of thermoplastic film and the outer walls of said second chamber being formed of a third sheet of thermoplastic film
