fig. 3 is a schematic view of a baffle configuration.
Description of the labeling: 1. a heat exchange pipe; 11. a fin; 12. a heat conducting block; 13. a groove; 2. a propeller; 21. a connecting shaft; 22. a blade; 23. a baffle; 231. and (6) guiding the flow.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments shown in the accompanying drawings.
Referring to fig. 1-3, the heat exchange area enhanced low-rib fin 11 of the present embodiment includes a heat exchange tube 1 and fins 11 disposed outside the heat exchange tube 1, the fins 11 are disposed outside the heat exchange tube 1 at equal intervals, a heat conduction block 12 is disposed between the fins 11 and the heat exchange tube 1, a plurality of grooves 13 are disposed in the heat exchange tube 1, the positions of the grooves 13 correspond to the positions of the fins 11 and the heat conduction block 12, and a plurality of propellers 2 are disposed in the heat exchange tube 1.
Through the technical scheme, the heat exchange area is enlarged by the heat conduction block 12, so that the heat exchange efficiency is improved, the distance between the liquid in the heat exchange tube 1 and the heat conduction block 12 and the distance between the liquid and the fins 11 are closer by the grooves 13, the heat conduction is faster, and the heat exchange efficiency is higher. The propeller 2 improves the flow velocity of liquid in the heat exchange tube 1, and can mix the liquid in the heat exchange tube 1, so that the liquid at the position of the groove 13 can be prevented from generating local high temperature, and the heat exchange efficiency is improved.
As a modified specific embodiment, the number of the propellers 2 is less than that of the fins 11, and a plurality of propellers 2 are equidistantly arranged in the heat exchange tube 1.
Through above-mentioned technical scheme, set up appropriate amount screw 2, the equidistance sets up in heat exchange tube 1, and the liquid spiral that drives in the heat exchange tube 1 that can be stable removes to mix the liquid in the recess 13, improve heat exchange efficiency.
As a modified embodiment, the propeller 2 corresponds to the groove 13 in its place.
Through above-mentioned technical scheme, the position of screw 2 corresponds with recess 13, and it is better to correspond the liquid derivation effect in the recess 13.
