造であることから、部品点数も多くなりコスト高となる
。Heat dissipation in the prior art is mainly carried out by the heat dissipation fins on the casing body and the lid with heat dissipation fins on both sides. Although the rise in temperature inside the casing depends on the surface area of the casing, the temperature rise of the heating element itself attached to the inner wall of the casing body is largely influenced by the shape of the radiation fins of the casing body. In addition, although the lid is attached to the housing body with screws, the contact thermal resistance is large and the heat dissipation effect due to heat conduction is small.Also, in order to improve assembly and maintenance workability, the lids are attached on both sides of the housing body. Since it is a structure in which the parts are attached, the number of parts increases, resulting in high costs.
本発明の目的は、放熱性を向上させかつ小型・軽量・低
価格化を実現することにある。An object of the present invention is to improve heat dissipation, and to achieve a reduction in size, weight, and cost.
放熱性の向」二は筐体本体をコ字形断面形状に変更して
、発熱素子の熱伝導をよくすることにより達成される。The second improvement in heat dissipation is achieved by changing the main body of the housing to a U-shaped cross section to improve heat conduction of the heating element.
また、部品点数も少なくてき低価格化が実現できる。In addition, the number of parts is reduced, making it possible to lower the price.
コ字形断面形状の筐体は、一体形状のる筐体に直接取付
けらオした発熱素子かｌらの熱伝導ば：３力向の放熱フ
ィンに対して効率的にできる。The casing having a U-shaped cross section can efficiently conduct heat from the heat generating element directly attached to the integral casing with respect to the heat dissipating fins in three directions.
従って、放熱フィンを小さくしても発熱体白身の許容温
度」二昇内に押さえることが可能となり、筐体の小型・
軽量化が実現できる。また、部品点数も減少することか
ら低価格化も可能となる。Therefore, even if the heat dissipation fins are made smaller, it is possible to keep the temperature of the heating element white within the allowable temperature range of 2.
Light weight can be achieved. Furthermore, since the number of parts is reduced, it is also possible to lower the price.
