Multi-flow heat exchange tube bundle with detachable cover plate

The utility model relates to the technical field of heat exchangers, in particular to a multi-flow heat exchange tube bundle with detachable cover plates, which comprises a rectangular support frame welded by channel steel, tube plates are respectively bolted at two ends of the support frame along the length direction, and cover plate components are hermetically bolted on the outer end surfaces of the tube plates. The cover plate assembly sequentially comprises a water passing cover plate and a plurality of sealing cover plates in the vertical direction. The cover plate assemblies on the two tube plates are in central symmetry and are sequentially communicated in a Z shape through a plurality of heat exchange tubes, and the heat exchange tubes are connected with the tube plates in a sealed mode. Therefore, the cover plate assembly is convenient to disassemble, the heat exchange tube is convenient to maintain, the assembling efficiency is improved, and the maintenance cost is reduced. 本实用新型涉及换热器技术领域，特别涉及一种可拆卸盖
