Modular heat exchangers in sterilization equipment heat exchange systems

Abstract

A modular heat exchanger for a sterilization equipment heat exchange system includes a tube body, a first cover plate, a second cover plate, and a plurality of inner tubes. The tube body has a first opening, a second opening, a first hole, and a second hole. The first cover plate has a plurality of first through holes penetrating the first cover plate. The second cover plate has a plurality of second through holes penetrating the second cover plate. The plurality of inner tubes are disposed inside the tube body corresponding to the plurality of first through holes and the plurality of second through holes. The number of inner tubes, first through holes, and second through holes is the same. Each inner tube corresponds to and communicates with one of the first through holes and one of the second through holes. The first hole, the tube body, and the second hole form a first flow channel. The first through hole, the inner tube, and the second through hole form a second flow channel. The first and second flow channels interweave within the tube body for heat exchange.
