Inlet and outlet I and tube side inlet and outlet II and the shell side inlet and outlet I and shell side inlet and outlet II being connected to shell, shell two of the invention
End is connected separately with tube sheet and end socket, it is characterised in that: and heat-exchanging tube bundle of the invention is made of several heat exchanger tube parallel arrangements, this
The structure of the heat exchanger tube of invention are as follows: the thin steel loop positioning column of heat exchanger tube entrance end fixed setting cross hang of the invention,
Support steel wire is fixedly mounted along heat exchange tube axis direction in the thin steel loop positioning column middle ware of cross hang of the invention, of the invention
Winding screw steel wire on steel wire is supported to form metal spiral steel ring.
Further, a fixed steel column connection supporting steel is arranged at interval of 4 ~ 6 screw pitch in metal spiral steel ring of the present invention
Line and metal spiral steel ring.
Further, the diameter of support steel wire of the invention is 2~5mm.
Further, spiral steel ring diameter of the invention is 1~2mm.
Further, metal spiral steel ring outer diameter size of the invention is the 2/5~3/5 of heat exchanger tube inner diameter size.
Beneficial effects of the present invention
1. of the invention upset the flowing of heat exchange tube fluid using spiral winding steel wire, it is suppressed that laminar flow of fluid in heat exchanger tube
Generation, fluid forms turbulent flow, improves convective heat-transfer coefficient α, and then improves heat exchange efficiency.
2. heat-exchanging tube bundle of the invention obtains structure and is made of several heat exchanger tube parallel arrangements, the knot of heat exchanger tube of the invention
Structure are as follows: the thin steel loop positioning column of heat exchanger tube entrance end fixed setting cross hang of the invention, positioning column of the invention it
Between heat exchange tube axis direction support steel wire is fixedly mounted, winding screw steel wire forms metal spiral steel on support steel wire of the invention
For circle so that fluid forms turbulent flow sharply in heat exchanger tube, that exchanges heat pipe inner wall washes away enhancing, can reduce dirt in this way
Attachment, extends effective service life of heat exchanger.
