The utility model provides a low-scaling spiral pipe type heat exchanger. The low-scaling spiral pipe type heat exchanger comprises a shell, a spiral pipe type heat exchange pipe installed in the shell, a heat supply piece arranged outside the shell and connected with the spiral pipe type heat exchange pipe, and a polymer thermal shrinkage structure wrapping the outer side of the spiral pipe type heat exchange pipe. Due to the fact that the polymer thermal shrinkage structure is arranged on the spiral tube type heat exchange tube of the low-scaling spiral tube type heat exchanger, when the heat exchanger starts to work, ion combination on the surface of the spiral tube type heat exchange tube can be reduced due to the existence of the polymer thermal shrinkage structure when crystals of harmful substances obtained after low-pressure evaporation, and therefore the heat exchange efficiency of the heat exchanger is improved. Therefore, the number of scales on the surface is reduced, and later cleaning after scal
