Abstract

The invention discloses a box type shell and tube heat exchanger. Buffer plates are arranged at an expanded inlet and an expanded outlet, play a role in impact prevention and prevent fluid from directly impacting tube bundles at the inlet and the outlet. A heat exchange tube is set to be of a sleeve structure which is formed by twining an inner tube and an outer tube concentric with the inner tube, so that heat exchange efficiency can be improved. Annular baffles are installed between the inner tube and the outer tube concentric with the inner tube and can be used for supporting the inner tube and improving turbulence of fluid in the tubes. The inner side of the inner tube is set to be of a thread structure, so fluid on the inner wall surfaces of the tubes can generate secondary flow and rotating flow, thinning of a boundary layer is facilitated, thermal resistance of the wall surfaces is reduced, and heat transfer is enhanced. The box type shell and tube heat exchanger has the advantages of being good in heat exchange effect and wide in applicability, and has broad market prospects.

Description
