Abstract
(EN) In the present invention a cooler is provided on the exterior of an electric motor that drives a fan, and the cooler is interposed midway along the length of a drainage pipe, causing a flow of drainage and thereby cooling the electric motor with drainage discharged to the outside of the motor. A cooling jacket (51a) is formed covering in a watertight manner the exterior (21a) of an electric motor (2a) that drives a fan (12a), a drainage inlet (52a) for introducing drainage and a drainage outlet (53a) for discharging drainage are provided above the cooling jacket (51a), and the drainage is made to flow from the drainage inlet (52a) to the drainage outlet (53a). Thus, the cold heat source of the drainage removed from the air can be used in cooling the electric motor (2a) driving the fan (12a) rather than being discharged directly to the outside of the motor, and the radiation of heat generated by the electric motor (2a) into the air to be cooled can be reduced, thereby enabling an air-conditioning device (1a) to operate in an energy-saving manner.
(FR) Selon la présente invention, un refroidisseur est disposé sur l'extérieur d'un moteur électrique qui entraîne un ventilateur, et le refroidisseur est interposé à mi-chemin le long de la longueur d'un tuyau de drainage, provoquant un écoulement de drainage, et refroidissant ainsi le moteur électrique avec un drainage évacué à l'extérieur du moteur. Une chemise de refroidissement (51a) est formée, recouvrant d'une manière étanche à l'eau l'extérieur (21a) d'un moteur électrique (2a) qui entraîne un ventilateur (12a), une entrée de drainage (52a) pour introduire un drainage et une sortie de drainage (53a) pour évacuer un drainage sont disposées au-dessus de la chemise de refroidissement (51a), et le drainage est amené à s'écouler à partir de l'entrée de drainage (52a) jusqu'à la sortie de drainage (53a). Par conséquent, la source de chaleur froide du drainage extrait à partir de l'air peut être utilisée pour refroidir le moteur électrique (2a) entraînant le ventilateur (12a), plutôt que d'être évacuée directement à l'extérieur du moteur, et le rayonnement de la chaleur générée par le moteur électrique (2a) dans l'air à refroidir peut être réduit, ce qui permet à un dispositif de climatisation (1a) de fonctionner d'une façon économe en énergie.
(JA)  送風機を駆動する電動機の外郭に冷却器を設け、冷却器をドレン配管の途中に介設してドレンを流動させることにより、電動機を機外に排出するドレンで冷却するようにした。 送風機12aを駆動する電動機2aの外郭21aを水密に覆う冷却ジャケット51aを形成し、冷却ジャケット51aの上方にドレンを導入するドレン入口52aとドレンを排出するドレン出口53aとを設けて、ドレンをドレン入口52aからドレン出口53aに流動させるようにして、空気中から除湿したドレンの冷熱源をそのまま機外に廃棄することなく送風機12aを駆動する電動機2aの冷却に利用することができ、電動機2aの発熱による冷却すべき空気への放熱を軽減して空気調和装置1aとしての省エネルギー運転を行うようにした。
