Abstract
Provided is a heat exchange tube bundle of a heat exchanger. The heat exchange tube bundle is disposed in the housing of the heat exchanger and comprises a plurality of heat exchange tubes. The heat exchange tube comprises a spiral winding section and extending straight pipes at two ends. The tail end of the extending straight pipe traverses a tube plate and is in a sealing connection with the tube plate. The tube plate is fixedly connected to the housing of the heat exchanger. The extending straight pipe is in parallel with the axis of the housing of the heat exchanger. The heat exchange tube bundle increases the heat exchange area of a heat exchanger, and improves heat exchange efficiency.
Description
Technical field
The utility model relates to technical field of heat exchangers, is specifically related to a kind of heat-exchanging tube bundle of heat exchanger.
