The invention discloses an ultrasonic crystals remover of heat exchange equipment. The ultrasonic crystals remover comprises a heat exchange device and a plurality of ultrasound generators. The ultrasound generators are linked to the outer surface of the heat exchange device and generate ultrasound to act on crystallizable solution flowing in the heat exchange device, thus crystallization of the crystallizable solution is decelerated, or already-generated crystals are vibrated to form the crystallizable solution again. The number of the ultrasound generators is not smaller than 1. The ultrasonic crystals remover is compact in structure, convenient to mount, use and maintain and effective to prevent the crystallization of the lithium bromide solution, and meanwhile, the crystallized lithium bromide solution is eliminated, and the conventional heat-pump cycle is unaffected.
