Abstract

The invention provides an evaporator for refrigerator defrosting based on a PTC (Positive Temperature Coefficient) heater. The evaporator for refrigerator defrosting based on the PTC heater comprisesthe PTC heater, fixing plates, radiating fins and an evaporation tube component, wherein the evaporation tube component comprises straight evaporation tube sections which are arranged in multiple rowsat intervals; the two ends of the straight evaporation tube sections are fixed by the fixing plates; the adjacent evaporation tube sections are connected by U-shaped tube sections of an evaporation tube; the PTC heater is arranged below the evaporation tube component; and the two ends of the PTC heater are connected to connecting terminals. The evaporator can effectively improve the defrosting efficiency and the defrosting area, can automatically adjust the temperature and keep constant temperature, avoids the occurrence of an empty burning phenomenon, and has safe and reliable electrical performances.

Description

technical field [0001] The invention relates to the technical field of refrigerator heaters, in particular to an evaporator for defrosting a refrigerator based on a PTC heater. Background technique [0002] The current conventional refrigerator defrosting evaporator equipment uses steel tube heaters and glass tube heaters, but the temperature of the steel tube heaters is very high, which is prone to fire hazards; while the glass tube heaters are easily broken, and the inside is also an electric heating wire.
