Method of welding thin plates heat exchange and heat exchanger plates welded produced according to the method.

摘要

Method for joining thin plates heat exchange material based on provided iron with access holes and a compression pattern of elevations and depressions over the area of ​​heat exchange of the plates and, if present, over the distribution area a heat exchanger plates, wherein the plates are coated with a brazing material and, before bonding, is arranged so that a contact between the elevations and adjacent depressions is obtained, after which the plates welded together at contact points formed, characterized in that 5-40%, preferably 10-30% of the heat exchange area and the range is coated with brazing material prior to welding.
