Component compound comprised of: a. a plurality of micro channel structures (1; 100), each of which b. having a plurality of micro channels running parallel to one another, defining a first portion of the micro channel structure, having an approximately rectangular cross section which has a larger width (Bs) in comparison with a height (Hs), and c. two wings laterally running to the outside from a surface wrapping the first portion from a side wall determining the height (Hs), and d. a lamellar structure comprising the following features: e. at least a first portion of the lamellar structure in a first plane, with the first portion providing a first connecting surface for the first micro channel structure (1; 100), f. at least a second portion of the lamellar structure in a second plane, with the second portion providing a second connecting surface for the second micro channel structure (1; 100), g. at least a first transversely running portion, which is arranged with a first end at the first portion of the lamellar structure and with an opposite second end at the second portion of the lamellar structure, and h. at least a second transversely running portion, which is arranged with a first end at the first portion of the lamellar structure or a further, adjacent first portion of the lamellar structure, and with an opposite second end at the second portion of the lamellar structure, with i. the two micro channel structures (1; 100) being connected with one another via the lamellar structure and running parallel to one another, with the lamellar structure having a width corresponding to at least a width of the micro channel structure and with the lamellar structure being in contact with the micro channel structure over the complete width of the micro channel structure, and the component compound is characterized in that j. the wings running to the outside extend parallel to a longitudinal axis of the first portion and k. a central recess is provided in the first and the second portion of the lamellar structure, the recess being adapted to the micro channel structure (1; 100) in the first portion of the micro channel structure (1; 100), with l. the at least one first transversely running portion enclosing a first angle α smaller than 90° at a first side with the first portion of the lamellar structure and enclosing a second angle β smaller than 90° at a second side, opposite to the first side, with the second portion of the lamellar structure, and with m. the at least one second transversely running portion enclosing a third angle γ smaller than 90° at a first side with the first portion of the lamellar structure or with the further first portion of the lamellar structure as well as a fourth angle δ smaller than 90° at a second side, opposite to the first side, with the second portion of the lamellar structure. a. a plurality of micro channel structures (1;
