Packing element for methods of exchange or conversion of materials designed as a heat-transfer element
First Claim
1. A packing element for methods of exchange or conversion of materials designed as a heat-transfer element, the packing element comprising a plurality of parallel layers which extend in a main direction (15) of a material stream and are formed by bodies (1) with hollow heat transfer channels (17) for a heat-transfer medium, each of the heat-transfer bodies (1) having a pair of shells (1a, 1b) made of a foil material and having side surfaces with a wave-shaped profile forming wave crests (141) the shells further having a relief-type profiling which forms a distribution and a collection channel system (121, 121'"'"') for the heat-transfer medium, a plurality of connection points located along the flow channels on the inner side of the shell pair capable of withstanding excess pressure of the heat-transfer medium, each of the shells having a wave-shaped inner region (10), a border zone (12) and a transition zone (11) between the inner region and the border zone, the heat-transfer channels (17) being situated in the inner region, and the distribution and collection channel system (121, 121'"'"') being situated in the border zone, the border zones (12) of the shell pair being made as mirror images of each other, and the inner regions (10) being made as inverse mirror images such that connection is established between the two shells.

Abstract
A heat-transfer element forms a packing element for material exchange or material conversion processes. The packing element has a plurality of parallel layers which extend in a main direction (15) of material flow and are formed by bodies (1) with hollow spaces (17) for a heat-transfer medium. Each of the heat-transfer bodies (1) has a pair of shells (1a, 1b) made from a foil-like material. The side surfaces of the shells are wave-shaped such that wave crests (141) are inclined with respect to the main direction (15) and that open flow channels crossing each other are provided between adjacent layers in mutual contact. The relief-like profiling of the shells (1a, 1b) provides a distribution and a collection channel system (121, 121'"'"') for the heat-transfer medium in addition to the heat-transfer channels (17). On the inner side of the shell pair a plurality of connection points may be made along the flow channels to form a connection which can withstand the excess pressure of the heat-transfer medium. The material of the shells ( 1a, 1b) is preferably a metal alloy and the profiling is made by pressing.
