Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a shell and tube condenser reinforces heat transfer device, it is including solid fixed ring 1, solid fixed ring 1 inner circle is equipped with first mounting bracket 2, first mounting bracket 2 center department fixed mounting has first connecting block 3, the cover is equipped with first bearing 4 on the first connecting block 3, first connecting

block

3 and 4 inner circle fixed connection of first bearing, 4 outer circles of first bearing evenly are equipped with a plurality of first flabellums 5, evenly a plurality of mounting holes 6 have been seted up on every first flabellum 5, equal fixed mounting has collar 7 in every

mounting hole

6, 7 inner circles fixed mounting of collar have

second mounting bracket
