The invention discloses a desktop computer mainframe box capable of dissipating heat intelligently. The desktop computer mainframe box comprises a PMW power amplification module, an information processor, a temperature sensor and a cooling copper tube. The cooling copper tube is embedded in a component placing plate; heat-dissipating fans are arranged at four side walls of a mainframe box main body; the temperature sensor is embedded in the side wall of the mainframe box main body and is connected with the information processor by electrically inputting; the information processor is connected with a controller by electrically inputting and is installed in an equipment cabinet bottom case; the PMW power amplification module is connected with the heat-dissipating fans by electrically inputting and is installed in the equipment cabinet bottom case. Because an intelligent control system composed of the temperature sensor, information processing, the controller and the PMW power amplification module is added in the desktop computer mainframe box capable of dissipating heat intelligently, the desktop computer mainframe box capable of dissipating heat intelligently could well control the rotating speed of the heat-dissipating fans so as to achieve better heat-dissipating effect. The desktop computer mainframe box capable of dissipating heat intelligently is simple in structure and convenient for popularizing.

The invention discloses an acrylic acid series copolymer-based adhesive sheet for a fifth generation (5G) antenna manufacturing process. The adhesive sheet includes an acrylic acid series copolymer and the acrylic acid series copolymer is composed of the following components according to parts by weight: 50-70 parts of iso-octyl acrylate, 10-20 parts of ethyl acrylate, 1-5 parts of hydroxyethyl acrylate, 2-6 parts of acryloyl morpholine, 3-6 parts of methyl acrylate, 10-20 parts of methoxy polyethylene glycol methacrylate, 0.1-0.5 part of azodiisobutyronitrile, and 150-200 parts of a solvent.The acrylic acid series copolymer of the invention can effectively improve the bonding performance and temperature resistance of the adhesive sheet to components of a 5G antenna and well control the high-speed stripping forces before and after undergoing high temperature and high humidity and has no pollution to an object to which the adhesive sheet is adhered.
