▎ 摘　　要

NOVELTY - The device has a double-layer cylinder container (1), a positioning device (5), a fixing device (6), and a platinum plate electrode clip (7) all placed on the magnetic stirring device (8). The platinum plate electrode clip is vertically suspended and arranged by the positioning device and the fixing device. The platinum plate electrode clip straightens the nickel-chromium alloy wire (10) and places horizontally. The thermocouple (11) is positioned in the inner cylinder of the double-layer cylinder through the positioning device. The digital display interface of the thermocouple is placed on one side of the double-layer cylinder. The stirring magnet (9) is placed in the inner cylinder of the double-layer cylinder. The outer layer of the double-layer tank container, the temperature-controlled water bath (2), and the conduit connection constitute a circulation loop. The power supply device (3) is connected to the platinum electrode clip through copper wires. USE - Temperature-controllable surface boiling coating device for boiling and depositing three-dimensional structure on curved surface used in fields of aerospace and civil automobiles. ADVANTAGE - The device adopts double-layer cylinder container and the temperature control water bath to form accurate and stable temperature control, without using the heating substrate placed at the bottom of the container for preheating, so that the boiling precursor solution whole temperature distribution is uniform. The device effectively avoids the problem of solute reunion and unstable caused by over-high temperature of the solution during the boiling and depositing process. The nickel-chromium alloy wire curved surface is uniformly distributed by non-template boiling deposition method, which has stable structure of three-dimensional structure graphene film, and greatly improves the surface nuclear boiling heat transfer application of bubble-shaped core and boiling performance.
