Is there an easy (cheap) way to identify aluminium alloys
Usually judge alloy aluminum plate quality time must pay attention to the appearance of brightness, survey bat bao hou is even even, pinch the board with the hand, feeling the elasticity and patience isn’t is good. Its main function is to make the moisture in the hot air on the heat exchange sheet coagulate into water droplets easily spread and flow down the aluminium sheet.


Do you really understand the aluminum sheet?
 
So to avoid for heat exchange area between the water affect the ventilation effect of heat exchanger, a “bridge” and then air conditioning heat exchange rate, under the condition of equal refrigerating capacity will also be able to save power.
Now, the usual hydrophilic aluminum foil on the market has good hydrophilicity in addition to its appearance, while the condensate remains between the heat exchanger. The difference is that the hydrophobic aluminum foil is intended to remove the condensate between the heat exchanger by increasing the contact Angle between the condensate and the heat exchanger, so that the condensate can form water drops that are prone to slip.
