S-shaped heat exchange pipe bundle

An S-shaped heat exchange pipe bundle comprises first S-shaped pipes and second S-shaped pipes, all of which are of a zigzag structure. The first S-shaped pipes and the second S-shaped pipes are embedded and arranged in a staggered manner. No gap exists between the pipe walls of the first S-shaped pipes and the pipe walls of the second S-shaped pipes in the longitudinal direction, and the pipe walls of the first S-shaped pipes and the pipe walls of the second S-shaped pipes are staggered by an S-shaped pipe elbow radius distance. Fluid can pass through the first S-shaped pipes and the second S-shaped pipes. A heat exchanger comprising the S-shaped heat exchange pipe bundle comprises an upper cover plate, a shell and a lower cover plate, and the S-shaped pipe bundle is arranged in the shell. The upper cover plate is provided with a liquid inlet hole so that cooling liquid can pass through the liquid inlet hole to be sprayed to the S-shaped pipe bundle.
