板式换热器底板

本发明公开了种板式换热器底板，包括底板本体（1），在底板本体（1）上堆叠布置有若干换热器板，所述底板本体（1）的左右两侧均向内折叠使左右两侧形成双层结构（2），双层结构（2）的内侧端部均朝上折弯形成纵侧边（3）；在每侧的双层结构（2）上均冲压有若干限定孔（4），限定孔（4）贯穿双层结构（2）的上层和下层，且上层底部经冲压向下方的外侧形成卷边（5），该卷边（5）将限定孔（4）位于下层的边缘包裹住；所述底板本体（1）的前后两侧也朝上折弯形成横侧边（6）；换热器板布置在两横侧边（6）和两纵侧边（3）之间。本发明在减重的同时，大大的提高了其稳定性。 The invention discloses a bottom plate of a plate type heat exchanger. The bottom plate of the plate type heat exchanger comprises a bottom plate body (1), wherein a plurality of heat exchanger plates are overlapped on the bottom plate body (1); the left side and the right side of the bottom plate body (1) are inwards folded to form double-layer structures (2); the inner side end parts of the double-layer structures (2) are upwards bent to form longitudinal side edges (3); a plurality of limiting holes (4) are punched in the double-layer structure (2) at each side and pass through the upper layer and the lower layer of the corresponding double-layer structure (2); the bottom parts of the upper layers are punched toward the lower outer sides
