Title (EN) TURBO COMPRESSOR HAVING SEPARATE COOLING AIR CHANNEL
(FR) TURBOCOMPRESSEUR À CANAL D'AIR DE REFROIDISSEMENT SÉPARÉ
(KO) 분리된 냉각 기로를 구비한 터보 압축기
Abstract: front page image
(EN) The present invention relates to a turbo compressor and more particularly, to a turbo compressor for compressing a gas such as air and supplying the same to the outside, the turbo compressor comprising: a compressed gas suction opening through which the gas is suctioned; an impeller for compressing the gas introduced through the compressed gas suction opening; a compressed gas discharge opening through which the gas compressed by the impeller is discharged to the outside; a compression unit having a compressed gas channel extending from the compressed gas suction opening to the compressed gas discharge opening; a motor having a rotating shaft, the front end portion of which is coupled to the impeller, in order to rotate the impeller; a housing having a motor containing space for containing the motor; and a cooling gas channel provided to extend through the motor containing space and formed such that a cooling gas contained therein can circulate, wherein the compressed gas channel is spatially separated from the cooling gas channel such that the gas inside the compressed gas channel cannot penetrate into the cooling gas channel. The present invention is advantageous in that the motor can be efficiently cooled with no compression loss occurring to the compression unit.
(FR) La présente invention concerne un turbocompresseur et, plus particulièrement, un turbocompresseur destiné à comprimer un gaz tel que de l'air et à le délivrer vers l'extérieur, le turbocompresseur comprenant : une ouverture d'aspiration de gaz comprimé à travers laquelle est aspiré le gaz ; une turbine servant à comprimer le gaz introduit à travers l'ouverture d'aspiration de gaz comprimé ; une ouverture d'évacuation de gaz comprimé à travers laquelle le gaz comprimé par la turbine est évacué vers l'extérieur ; une unité de compression comportant un canal de gaz comprimé s'étendant de l'ouverture d'aspiration de gaz comprimé à l'ouverture d'évacuation de gaz comprimé ; un moteur comportant un arbre tournant, dont la partie d'extrémité avant est couplée à la turbine, afin d'entraîner la turbine en rotation ; un carter comportant un espace de contenance de moteur destiné à contenir le moteur ; et un canal de gaz de refroidissement conçu de façon à s'étendre à travers l'espace de contenance de moteur et formé de sorte qu'un gaz de refroidissement contenu dans ce dernier puisse circuler, le canal de gaz comprimé étant spatialement séparé du canal de gaz de refroidissement de sorte que le gaz se trouvant à l'intérieur du canal de gaz comprimé ne puisse pas pénétrer le canal de gaz de refroidissement. La présente invention est avantageuse en ce que le moteur peut être refroidi efficacement sans perte de compression se produisant dans l'unité de compression.
(KO) 본 발명은 터보 압축기에 관한 것으로서, 공기 등의 기체를 압축하여 외부로 공급하는 터보 압축기로서, 상기 기체가 흡입되는 압축 기체 흡입구; 상기 압축 기체 흡입구를 통하여 유입된 기체를 압축하는 임펠러; 상기 임펠러에 의하여 압축된 상기 기체가 외부로 배출되는 압축 기체 배출구; 상기 압축 기체 흡입구로부터 상기 압축 기체 배출구까지 연결되어 있는 압축 기체 유로를 구비하는 압축 유닛; 상기 임펠러를 회전시키기 위하여, 전단부가 상기 임펠러와 결합되어 있는 회전축을 구비하는 모터; 상기 모터를 수용하는 모터 수용 공간을 구비한 하우징; 상기 모터 수용 공간을 지나가도록 마련되며, 내부에 수용된 냉각용 기체가 순환 가능하도록 형성된 냉각 기로;를 포함하며, 상기 압축 기체 유로는 상기 냉각 기로와 공간적으로 분리됨으로써, 상기 압축 기체 유로의 내부에 있는 기체가 상기 냉각 기로로 침투할 수 없는 것을 특징으로 한다. 본 발명에 따르면, 상기 압축 유닛의 압력 손실 없이 상기 모터를 효율적으로 냉각할 수 있는 효과가 있다.
