The utility model provides a
defrosting device for
cold chain transportation, and relates to the technical field of
defrosting devices. A containing frame used for containing articles is placed in the compartment, two guide rods are fixed in the compartment, a seat body is arranged on the two guide rods in a sliding mode, a liquid spraying
pipe is fixed to the seat body, a motor is fixed to the right end face of the inner wall of the compartment, and a first
threaded rod is fixed to an output shaft of the motor. The first
threaded rod is in threaded connection with the seat body. A motor drives a first
threaded rod to rotate, the position of a liquid spraying
pipe can be flexibly adjusted, and the liquid spraying
defrosting range and effect are greatly expanded through cooperation with spraying holes in a fan-shaped array shape below the liquid spraying
pipe; the wavy heating pipe in the
water storage tank increases the contact area with the liquid, so that the
heating efficiency of the liquid is remarkably improved, and the liquid with proper temperature is provided for defrosting; and through the arrangement of the heating block, the liquid spraying pipe is heated through the heating block, the spraying holes are effectively prevented from being frozen, and it is guaranteed that defrosting work is continuously and stably carried out.
