Description

本発明は、エンジン発電機に関し、詳しくは、予備用あるいは非常用として設置されるエンジン発電機に関する。   The present invention relates to an engine generator, and more particularly, to an engine generator installed for backup or emergency use.

エンジンで発電機を駆動して発電するエンジン発電機は、停電時や電力不足時の予備用あるいは非常用として多く用いられている。このような用途に用いられているエンジン発電機は、長時間停止状態におかれることが多いため、適宜ヒータを作動させて潤滑油を加温したり、バッテリを一時的に放電させてから充電することにより、非常時のエンジンの始動を円滑に行えるようにしたものが知られている(例えば、特許文献1参照。)。   Engine generators that generate power by driving a generator with an engine are often used for backup or emergency in the event of a power failure or power shortage. Since engine generators used for such applications are often stopped for a long period of time, the heater is appropriately operated to warm the lubricating oil, or the battery is temporarily discharged before charging. Thus, there is known one that can smoothly start the engine in an emergency (see, for example, Patent Document 1).

また、前述のような非常用などのエンジン発電機は、地下に設けられた発電機室などに設置されることが多く、風通しが悪いため、湿気によって電気回路に異常が発生するおそれがあった。このため、電気回路などを加温して乾燥させるためのヒータを設置することも行われている。   In addition, emergency engine generators such as those described above are often installed in a generator room or the like provided in the basement and are poorly ventilated, which may cause abnormalities in the electrical circuit due to moisture. . For this reason, a heater for heating and drying an electric circuit or the like is also installed.

特開2013−16446号公報JP 2013-16446 A

前述のようなヒータを設置する場合、パンチングメタルなどの通気性を有する材料からなる保護カバーでヒータを覆い、ヒータを保護することが一般的に行われている。ヒータ作動中は、保護カバーも高温になるため、点検作業などの際に保護カバーに手を触れると火傷するおそれがあった。   When the heater as described above is installed, it is generally performed to protect the heater by covering the heater with a protective cover made of a gas-permeable material such as punching metal. While the heater is operating, the protective cover also becomes hot, and there is a risk of burns if the hand is touched during inspection work.

そこで本発明は、ヒータ作動中に保護カバーが高温になることを抑制できる構造を備えたエンジン発電機を提供することを目的としている。   Accordingly, an object of the present invention is to provide an engine generator having a structure capable of suppressing the temperature of the protective cover during the heater operation.

上記目的を達成するため、本発明のエンジン発電機は、ケーシング内に、エンジンと、該エンジンによって駆動される発電機と、前記エンジン及び前記発電機を制御する制御装置と、ケーシング内を加熱するためのヒータとを収容したエンジン発電機において、前記ヒータの周囲を、通気性を有する保護カバーで覆うとともに、該保護カバーの外面にヒートシンクを設けたことを特徴としている。   In order to achieve the above object, an engine generator according to the present invention heats an engine, a generator driven by the engine, a control device for controlling the engine and the generator, and the casing in the casing. In the engine generator which accommodates the heater for this purpose, the periphery of the heater is covered with a protective cover having air permeability, and a heat sink is provided on the outer surface of the protective cover.

さらに、本発明のエンジン発電機は、前記ヒートシンクが、先端縁が連続した凹凸形状に形成された放熱フィンを有していること、あるいは、側面に、連続した三角形状の着色部を設けた放熱フィンを有していることを特徴としている。   Further, in the engine generator according to the present invention, the heat sink has a heat radiation fin formed in an uneven shape with a continuous leading edge, or a heat radiation in which a continuous triangular colored portion is provided on a side surface. It is characterized by having fins.

本発明のエンジン発電機によれば、ヒータの周囲を覆う保護カバーの外面にヒートシンクを設けているので、ヒートシンクからの放熱によってヒートシンクを含む保護カバーの温度を低くすることができ、手を触れても火傷することがなくなる。また、先端縁を凹凸形状に形成した放熱フィンや、側面に着色部を設けた放熱フィンによってヒートシンクを構成することにより、ヒートシンクに接触すると危険であることを視覚的に訴えることができるので、不用意に手で触れることを確実に防ぐことができ、安全性をより高めることができる。   According to the engine generator of the present invention, since the heat sink is provided on the outer surface of the protective cover that covers the periphery of the heater, the temperature of the protective cover including the heat sink can be lowered by the heat radiation from the heat sink, and the hand can be touched. No more burns. In addition, by constructing a heat sink with heat radiation fins with a rugged tip edge, or heat radiation fins with colored portions on the side, it is possible to visually appeal that it is dangerous to touch the heat sink. It is possible to surely prevent touching by hand, and the safety can be further increased.
