Abstract:
1. A heat exchange panel to be conformed to a complex shape, comprising: a first layer of a flexible material, which layer is conformable to a complex shape; a second layer of a flexible material, which layer also is conformable to a complex shape and has a common border with the first layer; a border seal sealing substantially an entire periphery of the first layer and the second layer at said border; and said first and second layers being directly secured together interiorly of said border at a multiplicity of points to from a dot matrix of attachments organized into first imaginary lines and second imaginary lines for connecting dots of said dot matrix to nearest dots of said dot matrix, said first imaginary lines crossing said second imaginary lines at an angle falling in a range of between about 70° to about 110°; wherein: the border seal consists of curvilinear ripples having ripple cycle lengths substantially shorter than the length of said border, forming an irregular border with respect to the dot matrix of attachments, in order to provide uniform flow and pressure, further comprising: a first port for passing fluid into the panel; a second port for passing said fluid out of the panel; and at least one fence interiorly of said border sealing the first layer and the second layer, said fence cooperating with said border to define a fluid flow channel within said panel, wherein: the fence includes curvilinear ripples having ripple cycle lengths substantially shorter than the length of the fence.
