Heat exchanger for accelerating heat exchange and heat exchange method

The invention provides a heat exchanger for accelerating heat exchange and a heat exchange method. The heat exchanger comprises a shell, end sockets, a liquid stirring device, a heat exchange pipe, stirring driving devices, the liquid stirring device and the heat exchange pipe are arranged in the shell, and the stirring driving devices are arranged in the end sockets. A heat exchange medium entersthe shell through a heat exchange medium feeding port, and flows out of the shell through a heat exchange medium discharging port. Materials enter the heat exchange pipe in the shell through a material feeding port and flow out of the heat exchange pipe through a material discharging port. The heat exchange medium is stirred, so that the heat exchange medium is in full contact with the heat exchange pipe, and the materials and the heat exchange medium achieve energy interchange through the pipe wall of the heat exchange pipe. According to the heat exchanger, the heat exchange medium is promoted to accelerate motion t
