Claims (1)
する油タンクの作動油を加熱する油加熱装置であ
つて、電気を熱源とする棒状の加熱器と、この加
熱器に油タンクの作動油が直接接触しないよう加
熱器を覆う被覆部材と、この被覆部材と加熱器と
の間に区画形成される中間室とを具備し、この中
間室には加熱器の熱を被覆部材に接触する油タン
クの作動油に伝播する熱媒体を充填して設け、こ
の熱媒体は油タンクの作動油とは異にし熱的安定
性を有する油として成る油加熱装置。 This is an oil heating device that heats the hydraulic oil in an oil tank that stores the hydraulic oil sucked and discharged by a hydraulic pump, and includes a rod-shaped heater that uses electricity as a heat source, and the hydraulic oil in the oil tank comes into direct contact with this heater. A covering member that covers the heater and an intermediate chamber defined between the covering member and the heater. An oil heating device that is filled with a heat transfer medium that propagates through oil, and the heat transfer medium is oil that has thermal stability, unlike the hydraulic oil in the oil tank.
