The invention provides a deep-sea supercritical carbon dioxide power system cooling device. The deep-sea supercritical carbon dioxide power system cooling device comprises a cooler; the turbulent flow structure comprises a recovery part, a plurality of magnetic parts arranged in the recovery part and a driver, the two ends of the recovery part communicate with the first heat exchange cavity and the second heat exchange cavity correspondingly, the driver is used for driving the magnetic parts to enter the first heat exchange cavity, each magnetic part is provided with a turbulent flow part, and the turbulent flow parts are arranged in the first heat exchange cavity. The turbulent flow part is used for changing the flowing direction of the carbon dioxide working medium when making contact with the carbon dioxide working medium. And the magnetic structure comprises an electromagnet arranged on the outer side of the shell, and the electromagnet is used for adsorbing the magnetic parts when being electrified, so that the magnetic parts are attached to the inner wall of the heat exchange pipeline. The invention provides a deep sea supercritical carbon dioxide power system cooling device which aims at solving the problem that in the prior art, when a carbon dioxide working medium passes through a shell-and-tube heat exchanger, the heat exchange capacity is low.
Description
technical field [0001] The invention relates to the technical field of deep-sea equipment cooling devices, in particular to a deep-sea supercritical carbon dioxide power system cooling device. Background technique [0002] In land power generation design, printed circuit board compact heat exchanger (PCHE) is usually used for cooling supercritical carbon dioxide. congestion etc. Therefore, from the perspective of applicability, the traditional shell-and-tube heat exchanger is still better. However, when the carbon dioxide working medium passes through the shell-and-tube heat exchanger, its heat transfer capacity is low. The heat transfer capacity is generally expressed by the heat transfer coefficient, and its general form is where λ is the thermal conductivity of carbon dioxide, D is the equivalent diameter, Re is the Reynolds number, and Pr is the Prandtl number. A, B, and C are coefficients related to fluid flow patterns. Generally, because the density and thermal c...
