CLOSED COOLING TOWER HAVING TUBESHEET COMBINED HEAT EXCHANGE PIECE

摘要

A closed cooling tower having a tubesheet combined heat exchange piece, comprising a tubesheet combined heat exchanger (8), a blower(4), a solution pump (5), a spray shower (6), a solution reservoir (7) and a frame (9); the combined heat exchanger of tube sheet (8) is formed by connecting a plurality of tubesheet combined heat exchange pieces with an inlet header and an outlet header; the tubesheet combined heat exchange piece comprises a heat transfer plate (2) and a coil pipe (1) formed by processing a heat exchange pipe; the heat transfer plate (2) is provided with a mounting groove (21), and the shape of the mounting groove (21) matches the shape of the coil pipe (1); the coil pipe (1) is mounted inside the mounting groove (21), and the gap between the coil pipe (1) and the mounting groove (21) is filled with a heat conductive bonding layer (3), the heat conductive bonding layer (3) enabling full contact between the heat transfer plate (2) and the coil pipe (1), so as to increase an effective heat exchange area of the coil pipe (1); the heat transfer plate (2) can guide a solution to form a continuous flow surface face and increase a solution heat exchange surface area, improving the heat exchange efficiency as well as reducing the cooling tower volume.
