The invention relates to the technical field of heat exchangers, in particular to a shell and tube type heat exchanger. The shell and tube type heat exchanger comprises a tube plate and shell covers.Multiple tube bundle punching areas are arranged on the tube plate, and multiple tube bundle holes are formed in any tube bundle punching area. The multiple shell covers cover the corresponding tube bundle punching areas, and pipeline connectors are formed in the shell covers. According to the shell and tube type heat exchanger, the shell covers only bear fluid pressure between the shell covers and the tube bundle punching areas, and the shell covers and the tube plate are connected in a welded manner, so that the shell and tube type heat exchanger has better pressure bearing performance. 本发明涉及换热器技术领域，具体涉及一种壳管式换热器。包括管板和壳盖，管板上设有多个管束穿孔区，任一个管束穿孔区内具有多个管束孔；壳盖有多个，覆盖在对应的管束穿孔区上，壳盖上设有管路接口。本发明中，壳盖只承受其与其与管束穿孔区之间的流体压力，而且，壳盖与管板之间通过焊接的方式连接，使得该壳管式换热器具有更好的承压性能。
