摘要： PROBLEM TO BE SOLVED: To provide a means for preventing increase in temperature due to the heat generated from a power element that is radiated inside of a casing. SOLUTION: In the casing having a heat radiation section and a cooling fan, a guide extended by a prescribed value to the heat radiation section is provided at one portion of the casing. When the guide section forcedly air-cools the cooling fan, the air heated by a substrate generating much heat flows into a substrate, generating a relatively small amount of heat that prevents the substrate generating a relatively small amount of heat from being warmed. Thus, for example the substrate generating much heat is arranged at a position near the cooling fan, as compared with the substrate generating a relatively small amount of heat. Alternatively, the substrate generating much heat is arranged at a position near an intake surface, as compared with the substrate that generates a relatively small amount of heat. The guide section is provided in the casing, enabling heat radiation in the substrate generating much heat that generates a relatively small amount of heat, or the like, and enables reduction in the temperature increase.

摘要翻译：要解决的问题：提供一种用于防止由于辐射在壳体内部的功率元件产生的热量引起的温度升高的装置。解决方案：在具有散热部和冷却风扇的壳体中，在壳体的一部分设置有向规定值延伸到散热部的引导件。当引导部分强制地冷却冷却风扇时，由产生大量热量的基板加热的空气流入基板，产生相对少量的热量，以防止基板产生相对少量的热量而被加热。因此，例如，与产生较少量的热量的基板相比，产生大量热量的基板被布置在靠近冷却风扇的位置。或者，与产生较少量的热量的基板相比，产生大量热量的基板被布置在靠近进气表面的位置。引导部分设置在壳体中，使得基板中的热辐射产生产生相对少量热量的大量热量，并且能够降低温度升高。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a high-performance power conversion apparatus of high reliability at a low cost. SOLUTION: A circuit board 4 on which a peripheral circuit element 5 such as a control circuit is mounted is placed at a height different from a base board 1 on which a power element 2 is mounted by being shifted from the board 1 in a lateral direction in a case 30. Further, the bottom 31 of a part in the case 30 where the circuit board 4 is housed is formed at a different height so as to be isolated from a heat radiation fin 7. Thereby a rise in the temperature of the circuit board 4 due to the heat generation of the power element 2 is restrained. COPYRIGHT: (C)2004,JPO
