Abstract: Through the analysis of Chinese scholars on the research achievements of super-wide temperature refrigerator, using the aluminum foil heater project to explore the feasibility of heating in variable temperature compartment, through CFD simulation and prototype production, proving that using the mentioned method can make variable temperature compartment have the conditions to adjust the temperature between -18℃ to 45℃, the air temperature uniformity is well, the maximum temperature difference controlled in 5 ℃ or so, the surface of the aluminum foil heater heating temperature is relatively low, can well protect the inner of the refrigerator.

Key words: Super-wide temperature refrigerator, Variable temperature compartment, Aluminum foil heater
