Abstract

The making process of heat transferring element includes the following steps: compressing metal sheet between the upper mold and the lower mold of compressing formation apparatus to form the required irregular shape of the heat transferring element for heat exchanger; and compressing slender material fed longitudinally in the single direction in the mold shorter than the slender material to prepare several heat transferring elements with irregular pattern longitudinally.

Description

technical field [0001] The present invention relates to a method of manufacturing a heat transfer element for a heat exchanger by press-forming a material to be processed, in particular to a method of pressing the material to be processed multiple times to obtain a plurality of irregular patterns set, Thereby a method of manufacturing a heat transfer element. Background technique [0002] The heat transfer element of a heat exchanger, usually formed from sheet metal, is pressed into a prescribed shape to form a usable finished product. For the manufacture of heat transfer elements using press-forming devices, a set of metal molds is usually used. More specifically, the material to be processed is sandwiched between two dies. The dies are moved close to each other, creating irregular patterns on the sheet metal of the material to be processed that act as heat transfer surfaces. [0003] Press-forming of heat transfer elements is usually achieved in this way. A set of mold...
