Abstract:
A method of producing a flexible heat-exchange device including a body having a mutually joined plurality of flexible mats and an internal passageway for a heat-carrying fluid, an inlet and an outlet, comprising the steps of:placing a first plastic elastic mat and a second plastic elastic mat in a mould die having supporting surfaces and recesses around said supporting surfaces, respectively; separating the first and second plastic elastic mats by a resilient counterdie; bringing the mould dies together with the first and second plastic elastic mats separated by said resilient counterdie into contact with one another wherein the first and second plastic elastic mats are stretched down around abutment surfaces by deformation of the resilient counterdie and around the support surfaces and down into said recesses so as to obtain local plastic deformations as the mould dies are brought together; placing the second plastic elastic mat over the first plastic elastic mat; and mutually joining said first and second plastic elastic mats to form said body.
