摘要

The apparatus has a heating element (307) that is placed in an envelope presenting openings for passage of air on an upper part and a lower part. A heating unit (308) i.e. armor-plated electrical resistance, is integrated in a heating body (309) that is intended to be placed in planes (X, Z) that are arranged in an approximately vertical manner. A set of curved fins (315) is placed with regard to the planes, where the fins are arranged to deviate from/to each other from bottom to top.
