Embodiment Construction

[0019] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0020] A process for manufacturing a hydrophilic film of an aluminum heat sink, comprising the steps of:

[0021] Step 1: Uncoiling; the uncoiling warp is 150 to 1000mm, the uncoiling tension is 0 to 350N, and the aluminum foil line speed is 1 to 50m / min;

[0022] Step 2: Degreasing; the concentration of ingredients is aluminum degreasing liquid: water = 1:1, the temperature is 50 to 70 degrees, and the time is 120 to 240s for the residence time of aluminum foil rinsing and spraying;

[0023] Step 3: Rinse with water; the temperature is 45 to 55 degrees, and the time is 90 to 180s for aluminum foil rinsing;

[0024] Step 4: Rinse with deionized water; the time is 60 to 120s for aluminum foil;

[0025] Step 5: Dry with hot air;

[0026] Step 6: roller coating...

Abstract

The invention relates to a process for manufacturing a hydrophilic membrane of an aluminum radiating fin, comprising the following steps: step 1: uncoiling; step 2: degreasing; step 3: rinsing with water; step 4: rinsing with deionized water; step 5: drying through hot air; step 6: coating through a roller, wherein a coating composition is the coating composition which contains an acrylic polymer body and ionic surfactant; step 7: stoving and solidifying; step 8: cooling. The aluminum radiating fin comprises an aluminum plate and a hydrophilic membrane which is formed on the surface of the aluminum plate, wherein the hydrophilic membrane is manufactured according to the process. The process for manufacturing the hydrophilic membrane of the aluminum radiating fin has the following beneficial effects: elongation and an erishen value are stable and good in case that strength is ensured, product yield is improved, economic benefit is improved, and user requirements are met.

Description

technical field [0001] The invention relates to a manufacturing process of a hydrophilic film of an aluminum heat sink. Background technique [0002] In air conditioners, due to the conspicuousness of problems such as global warming and energy shortage, there is an increasing demand for performance improvement such as high efficiency and miniaturization of air conditioners. Due to such demands, aluminum materials are widely used in heat exchangers of air conditioners due to their excellent thermal conductivity, workability, corrosion resistance, and the like. Furthermore, in order to perform heat exchange efficiently and to reduce the space, the heat exchanger has a structure in which aluminum radiating sheets are arranged side by side at narrow intervals. When the air conditioner is in operation, if the temperature of the surface of the heat dissipation sheet is below the dew point of the air, the condensed water adhering to the surface of the heat dissipation sheet will c...
