Abstract

The invention provides a heat exchanger, an air conditioner and a machining method for metal foils. The heat exchanger comprises multiple metal foils and refrigerant pipes matching the metal foils. Surfaces of the metal foils are engraved with multiple grooves and multiple stripe-shaped protrusions. Due to the multiple grooves and the multiple stripe-shaped protrusions, the metal foils have hydrophilic properties. The air conditioner is provided with the above heat exchanger. The machining method for metal foils comprises following steps: firstly, adopting a laser to engrave the grooves in surfaces of the metal foils for multiple times till the number of the grooves reach at the pre-set value, secondly, utilizing the laser to engrave the grooves in a deepening mode for multiple times till the depths of the grooves reach the pre-set depth. The heat exchanger, the air conditioner and the machining method for metal foils have following beneficial effects: hydrophilic surfaces of the metal foils have high heat exchange rate and fine durability; a simple process is obtained; and high dimensional accuracy is achieved.

Description

technical field [0001] The invention relates to the refrigeration field, and more specifically, to a heat exchanger, an air conditioner and a metal foil processing method. Background technique [0002] At present, during the cooling process of the air conditioner, the temperature of the aluminum fins of the evaporator is below the dew point, and the condensed water formed on the surface of the aluminum fins has two negative effects on the heat transfer of the evaporator. Second, reduce the air intake area of ​​the evaporator and increase the air intake resistance. Therefore, the surface of the aluminum fins of the evaporator is usually provided with a hydrophilic coating to increase the wettability of the surface and reduce the contact angle of the surface of the aluminum fins, thereby improving the heat exchange efficiency. However, the existing hydrophilic coatings are often organic resins, whose durability needs to be improved and whose thermal conductivity is high, so t...
