Title:
アルミニウム又はアルミニウム合金からなる熱交換器
Document Type and Number:
Japanese Patent JP5712777
Kind Code:
B2
Abstract:
Provided is a heat exchanger including a heat exchange fin in which frost formation at the time of heater operation can be prevented to the extent possible, and under such a condition that condensation is liable to occur on a fin surface, a water droplet of condensed water can be quickly removed by bringing the water droplet into contact with a hydrophilic film, and as a result, a favorable heat exchange function can be continuously obtained without any increase in ventilation resistance. The heat exchanger includes a heat exchange fin made of an aluminum plate material that has a crosslinked hydrophobic film having a frost formation-suppressing effect and a hydrophilic film, in which: an area occupied by the crosslinked hydrophobic film in a square area measuring 10 mm by 10 mm at an arbitrary position on a surface of the heat exchange fin is 20 to 80%; and the crosslinked hydrophobic film is formed of an aqueous hydrophobic coating composition containing a resin (A) having a fluorine atom-containing group, a quaternary ammonium salt group-containing modified epoxy resin (B), and an amino resin (C) in which the solid content of the resin (A) is 1 to 30 parts by mass with respect to 100 parts by mass of the total of the solid contents of the resin (B) and the resin (C).
