Beschreibung
Zusammenfassung:	The invention discloses a locally-thickened plate-fin type main heat exchanger. The locally-thickened plate-fin type main heat exchanger comprises thickening plates which are arranged at the outermost sides around a plate fin; and a process layer is also arranged at the inner side of each thickening plate. The locally-thickened plate-fin type main heat exchanger has the advantages that the same effect as the existing structure can be reached after decreasing more than two process layers from the thickening plates and remaining the welding distance of a seal head, and therefore, the cost of the main heat exchanger is decreased; the weight of the main heat exchanger is reduced, and the production cost is decreased.
