Hot switch chip with additional strengthening

The utility model provides a heat exchanger technical field's hot switch chip with additional strengthening, includes through stamping forming's plane sheet metal and sets up at plane sheet metal turn-ups all around, the turn -ups for being the end to end's of a constant angle degree slice plate structure with the plane sheet metal, the turn -ups is equipped with a plurality of hollow strengthening ribs on the turn -ups direction of height. The utility model discloses the department increases additional strengthening at hot switch chip turn -ups to the bad welding condition such as the greatdeflection of the local appearance of turn -ups are avoided to turn down rims deflection among the control welding process. 种换热器技术领域的具有加强结构的热交换芯片，包括通过冲压成型的平面薄板及设置在平面薄板四周的翻边，所述的翻边为与平面薄板呈定角度的首尾相连的片状板材结构；所述翻边于翻边高度方向上设有若干空心加强筋。本实用新型在热交换芯片翻边处增加加强结构，以控制焊接过程中翻边的变形量，避免翻边局部出现较大变形量等不良焊接情况。
