Rapid heating and radiating device for cylindrical container

The utility model discloses a rapid heating and radiating device for a cylindrical container. A heating and heat dissipation jacket of the device is of a sleeve-shaped structure made of a high-heat-conducting-performance material, 2N through holes which are evenly distributed are formed in the wall of the heating and heat dissipation jacket, the N through holes which are arranged at intervals are used for installing heating rods, and the remaining N through holes are communicated end to end through metal pipe welding to form a heat dissipation channel. According to the device, an electric heating mode is adopted, and rapid heating of the cylindrical container is achieved; a liquid cooling and air cooling combined heat dissipation mode is adopted, so that rapid heat dissipation of the cylindrical container is realized; the heat preservation cover of the cylindrical container is made into a quick-opening structure, disassembly is convenient, and heat dissipation is accelerated. The utility model is mainly appli
