APPARATUS FOR THE TRANSFER OF HEAT OR COLD TO A TRANSPORT FLUID FLOWING THROUGH THE APPARATUS

摘要

The device is comprised of two resilient superposed layers of a synthetic material. At least one of these layers (1 or 2) shows on its side facing the other layer (2 or 1) some protrusions (7, 8) and/or some ribs (3-6, 17, 18) to form connecting channels (16). This layer is connected with the other layer, at least locally, through the upper surface of the protrusions (7, 8) and/or of the ribs (3-6, 17, 18). Between the input channel (19) and the output channel (20), are disposed one or several compensation channels (21). Depending on the kind of synthetic material and the charge of heat or cold, some input and output openings are disposed at certain given locations so as to avoid undesirable overpressures between the layers. The device consists of a narrow band (28) which can be unwound, the longitudinal channels of which are linked together with transversal channels in a tight link on the perpendicular face of the band (28) by means of lateral profiles (23). The longitudinal and transversal channels (29) are so dimensioned as to allow the circulation of a steady flow having a liquid specific volume less than 11/ms.
