This project is a 3U server host designed by the company for TEDC. "It" is a standard 19-inch 3U box. The equipment is used in the industrial field. The overall modeling of the box is scientific and technological, simple and strong. Galvanized sheet is used for sand blasting and oxidation, and the collision between modeling and material makes the product have more visual impact and highlights the aesthetics and professionalism of the product. The upper and lower cover plates of the chassis are designed according to the natural honeycomb style opening, which is elegant and beautiful, and can improve the heat dissipation performance. At the same time, taking into account the actual use of users in the design, from the handle, the plugging aid, to the installation of aluminum alloy slide rails inside the chassis, and the installation kit, every component that will be used has been carefully designed to make customers use it smoothly and work more efficiently.
