Improve the high-efficiency turbulent flow shell-and-tube heat exchanger of heat exchange efficiency.
A kind of turbulent flow shell-and-tube heat exchanger, including shell and it is built in the intracorporal heat-exchanging tube bundle of shell, the utility model changes
The baffle plate of heat-exchanging tube bundle is provided perpendicular among heat pipe bundle, the hull outside wall of the utility model is equipped with to be connected with heat exchanger tube
Logical tube side 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, this is practical
Novel shell both ends are connected separately with tube sheet and end socket, it is characterised in that: the heat-exchanging tube bundle of the utility model is by several heat exchange
Pipe parallel arrangement composition, the structure of the heat exchanger tube of the utility model are as follows: the heat exchanger tube entrance end of the utility model is fixedly installed
The thin steel loop positioning column of cross hang, the utility model cross hang thin steel loop positioning column middle ware along heat exchanger tube axis
Support steel wire is fixedly mounted in direction, and winding screw steel wire forms metal spiral steel ring on the support steel wire of the utility model.
Further, a fixed steel column connection branch is arranged at interval of 4 ~ 6 screw pitch in the utility model metal spiral steel ring
Support steel wire and metal spiral steel ring.
Further, the diameter of the support steel wire of the utility model is 2~5mm.
Further, the spiral steel ring diameter of the utility model is 1~2mm.
Further, the metal spiral steel ring outer diameter size of the utility model is the 2/5~3/5 of heat exchanger tube inner diameter size.
The beneficial effects of the utility model
1. the utility model has upset the flowing of heat exchange tube fluid using spiral winding steel wire, it is suppressed that in heat exchanger tube
The generation of laminar flow of fluid, fluid form turbulent flow, improve convective heat-transfer coefficient α, and then improve heat exchange efficiency.
2. the utility model, which obtains heat-exchanging tube bundle, to be obtained structure and be made of several heat exchanger tube parallel arrangements, the utility model is changed
The structure of heat pipe are as follows: the thin steel loop positioning column of the heat exchanger tube entrance end fixed setting cross hang of the utility model, in this reality
Support steel wire is fixedly mounted with the tube axis direction that exchanges heat between novel positioning column, winds spiral shell on the support steel wire of the utility model
Rotation steel wire forms metal spiral steel ring and fluid is made to form turbulent flow sharply in heat exchanger tube, and that exchanges heat pipe inner wall washes away increasing
By force, the attachment that can reduce dirt in this way extends effective service life of heat exchanger.
