産業上の利用分野
本発明は、硬質アルミニウム箔上に親水性塗膜を備えた
熱交換器用フィン材に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fin material for a heat exchanger comprising a hydrophilic coating film on a hard aluminum foil.
従来技術とその問題点
熱交換器においては、放熱特性および冷却特性を向上さ
せるために、放熱部および冷却部の表面積を出来るだけ
大きくする必要があり、フィンの間隔が極めて狭くなる
構造が採用されている。Prior art and its problems In heat exchangers, in order to improve heat dissipation and cooling characteristics, it is necessary to increase the surface area of the heat dissipation section and cooling section as much as possible, and a structure in which the spacing between the fins is extremely narrow is adopted. ing.
この冷却部においては、大気中の水分が、密接したフィ
ン間で凝縮しやすい。凝縮した水は、通常使用されてい
るアルミニウム製フィン材の表面が疎水性であることか
ら、水滴を形成して、フィン間の目詰まりを起こし、熱
交換効率を低下させる。In this cooling section, moisture in the atmosphere tends to condense between closely spaced fins. Since the surface of commonly used aluminum fin materials is hydrophobic, the condensed water forms water droplets, causing clogging between the fins and reducing heat exchange efficiency.
現在親水性を付与するために、アルミニウム製フィン利
の表面に下記の如き親水性塗膜を形成することが行われ
ている。Currently, in order to impart hydrophilic properties, a hydrophilic coating film as described below is formed on the surface of aluminum fins.
（イ）アルミニウム上にシリカまたは炭酸カルシウムを
含有する樹脂塗膜を形成する。しかしながら、この塗膜
は、親水性に乏しいので、所望の効果を十分に奏し得な
い。(a) Forming a resin coating containing silica or calcium carbonate on aluminum. However, since this coating film has poor hydrophilicity, it cannot sufficiently exhibit the desired effect.
（ロ）アルミニウム上にアルマイト皮膜、ベーマイト皮
膜またはクロメート皮膜を形成し、その上に水ガラスま
たはコロイダルシリカ膜を形成する。(b) An alumite film, a boehmite film, or a chromate film is formed on aluminum, and a water glass or colloidal silica film is formed thereon.
この場合、膜の親水性は、良好であるが、フィン材への
成形加工時に膜成分の一部が剥離し、粉となって飛散し
てしまうので、結局所望の効果が十分には達成されない
。In this case, the hydrophilicity of the film is good, but some of the film components peel off during the forming process into the fin material and scatter as powder, so the desired effect is not fully achieved. .
（ハ）また、アルミニウム上に直接水ガラスまたはコロ
イダルシリカを塗布することも行われているが、この場
合にも、やはりフィン材への成形加工時に膜成分の一部
が剥離し、粉となって飛散してしまうので、所望の効果
は十分には達成されない。(c) Water glass or colloidal silica is also applied directly onto aluminum, but in this case too, some of the film components peel off and turn into powder during the forming process into the fin material. The desired effect is not fully achieved because the particles are scattered.

レンなどが用いられる。The hydrophilic coating film formed on the aluminum material contains (a) 15 to 35 parts by weight of at least one of styrene-modified acrylic-melamine resin, epoxy resin, and styrene-methacrylate resin, and (b) 85 parts by weight of activated alumina fine particles.
~65 parts by weight, for a total of 100 parts by weight. The resin component plays the role of a binder between activated alumina fine particles and the role of supporting alumina fine particles on aluminum. If a resin other than those mentioned above is used as the resin component, the adhesion of the coating film to aluminum may be insufficient and peeling of the coating film may occur during molding into a fin. Activated alumina as a hydrophilic filler component is porous and has a large specific surface area.
Compared to silica and calcium carbonate, which are conventionally used as hydrophilic filler components, it has excellent water resistance, heat resistance, etc., and also has a moderate adsorption power for moisture (high catalytic activity). The particle size of activated alumina is 5 μm or less, with an average of 3
It is preferable to set it to about μm. If the amount of the resin component is too small (the amount of activated alumina is too large), the adhesion of the coating film to aluminum will be insufficient, while if it is too large (the amount of activated alumina is too small), The hydrophilicity of the coating film becomes insufficient. In order to maintain the hydrophilicity of the coating film over a long period of time, it is necessary that the upper part of the activated alumina protrudes from the surface of the resin coating film. Therefore, the appropriate thickness of the coating film is about 3 to 5 μm. The coating film may be formed by applying an oil-based paint containing a solvent component and activated alumina to the surface of a hard aluminum foil to be used as a fin material by a method such as gravure coating or roll coating, and drying the coating. As a solvent component,
Methyl ethyl ketone, n-butanol, toluene, xylene, etc. are used.

ンへの成形加工時にも剥離することがない。Effects of the Invention Since the coating film provided on the surface of the fin material for a heat exchanger according to the present invention has excellent adhesion to the aluminum substrate, it does not peel off during molding into fins.
また、塗膜自体が親水性に優れているので、凝縮した水
分が水滴を形成して、フィン間の目詰まりを起こすこと
は、実質上防止される。Further, since the coating film itself has excellent hydrophilicity, it is substantially prevented that condensed water forms water droplets and causes clogging between the fins.
