Adjustable tube plate cooling structure

The utility model discloses an adjustable tube plate cooling structure, which belongs to the technical field of heat exchangers and comprises a fixed plate, a movable plate opposite to the fixed plate is arranged on one side of the fixed plate through a cross rod, and a guide rod penetrating through the movable plate is fixedly mounted below the fixed plate. An opening is formed in the upper portion of the movable plate, and a rolling wheel in rolling connection with the top of the transverse rod is rotationally connected to the upper portion of the opening. Compared with the prior art, according to the adjustable tube plate cooling mechanism, the friction mode between the rolling wheels and the transverse rod is changed from sliding friction to rolling friction, friction force is reduced, meanwhile, the adjustable tube plate cooling mechanism needs to be used in cooperation with lubricating oil under interference connection, the adjustable tube plate cooling mechanism does not need to be used in cooperation
