Aluminium is a relatively soft,durable, lightweight, ductile and malleablemetal with appearance ranging from silvery to dull gray,depending on the surface roughness. It is nonmagnetic and does not easilyignite. A fresh film of aluminium serves as a good reflector (approximately92%) of visible light and an excellent reflector (as much as98%) of medium and far infrared radiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the density and stiffnessof steel. It iseasily machined,cast, drawn and extruded.

According to the order of the thermal conductivity of the metal, corrosion resistance and production cost, refrigerator interior sheet metal is chosen instead of aluminum other metals, to ensure its good thermal conductivity of the premise, as far as possible to reduce costs and the choice of corrosion-resistant material processing, aluminum is the best choice.
Secondly, in order to increase the length of the liner internal exchange area and the outside air heat, refrigerator interior selected embossing plate instead of the flat plate. In the absence of refrigerator interior space cause pressure to increase the use of embossed aluminum air tank wall contact area for a more efficient uniform heat exchange.

Speaking on the cooling rate: according to the laws of physics, thermal conductivity of aluminum is 237W / mK, the thermal conductivity of iron is 80W / mK, the thermal conductivity of the larger the number, the better the thermal conductivity, under the same conditions cooling faster the cooling effect is better. Using embossed aluminum evaporator, cooling rate is 3 times the wire tube evaporator. You can do a little to test in the refrigerator freezer compartment through an aluminum plate on a drop of water drops, 5 seconds into the ice, cooling is very fast!
