EDGE STRIPS WITH SURFACE STRUCTURE FOR PLATE HEAT EXCHANGER

The invention relates to a plate heat exchanger (1) having a plurality of parallel heat exchanger passages (3) which are separated from one another by separating plates (4, 5). Each heat exchanger passage (3) is delimited on at least one side by an edge strip (8), and each edge strip (8) has a first...

Zusammenfassung:	The invention relates to a plate heat exchanger (1) having a plurality of parallel heat exchanger passages (3) which are separated from one another by separating plates (4, 5). Each heat exchanger passage (3) is delimited on at least one side by an edge strip (8), and each edge strip (8) has a first surface (81) and a second surface (82) facing away from the first surface (81). The two surfaces (81, 82) are soldered to a respective paired separating plate (4). According to the invention, each of the two surfaces (81, 82) has a surface structure (9) with a plurality of uniformly arranged elevations (802) and depressions (801), and the distance (B) from one elevation to an adjacent elevation (802) or from one depression to an adjacent depression (801) ranges from 0.1 mm to 2.5 mm. 本发明涉及种板式换热器(1)，具有多个平行的热交换路径(3)，所述热交换路径被分隔板(4,5)相互分隔开，其中，对应的热交换路径(3)在至少侧被边缘板条(8)限界，并且，每个边缘板条(8)具有第表面(81)和背离第表面(81)的第二表面(82)，并且，两个表面(81,82)各与个配属的分隔板(4)钎焊。根据本发明设置为，两个表面(81,82)分别具有表面结构(9)，所述表面结构具有多个规则布置的凸起(802)和凹陷(801)，其中，凸起与相邻凸起(802)或凹陷与
