Description

Technical Field

[0001] The utility model relates to the technical field of electrodeposition, in particular to an in-tube flow electrodeposition device in a horizontal direction. Background Art

[0002] The preparation of porous structures in round tubes has important applications in the field of heat and mass transfer. For example, after the porous structure is prepared in the tube, it can be injected with liquid, packaged and processed into a heat pipe, which becomes a device that transfers heat through the phase change of the working fluid inside the fully enclosed tube shell. As a highly efficient heat dissipation component today, heat pipes are widely used in aerospace, military industry, chip microelectronics and other industries. Its heat dissipation efficiency is several orders of magnitude higher than that of traditional copper tubes. The most critical part is the capillary core in the heat pipe. This porous structure prepared in the round tube is the capillary core of the heat pipe, which can promote the reflux of the working fluid in the heat pipe and enable the heat pipe to complete the gas-liquid two-phase circulation. However, in the prior art, it is impossible to prepare a capillary core with a uniform overall structure in the horizontal direction without being affected by gravity. Utility Model Content
