Abstract
(EN)
A motor rotor (21), a compressor, a refrigerant circulation system, and a cooling device. The motor rotor (21) comprises: a hollow portion, which is disposed at an inner part of the motor rotor (21) and which communicates with an end portion of the motor rotor (21) that is used for a compression unit rotation portion connected to the compressor; and a vent hole, which communicates with the hollow portion and a radial outer side of the motor rotor (21). The compressor comprises the aforementioned motor rotor (21). The present motor rotor (21) and the compressor may solve the problem of heat concentration of the motor rotor (21), which is beneficial in ensuring that a motor in the compressor cools fully, and achieves efficient and reliable operation.
(FR)
La présente invention concerne un rotor de moteur (21), un compresseur, un système de circulation de fluide frigorigène et un dispositif de refroidissement. Le rotor de moteur (21) comprend : une partie creuse, qui est disposée au niveau d'une partie interne du rotor de moteur (21) et qui communique avec une partie d'extrémité du rotor de moteur (21) qui est utilisé pour une partie de rotation d'unité de compression reliée au compresseur ; et un trou d'évent, qui communique avec la partie creuse et un côté extérieur radial du rotor de moteur (21). Le compresseur comprend le rotor de moteur (21) susmentionné. Le présent rotor de moteur (21) et le compresseur peuvent résoudre le problème de la concentration de chaleur du rotor de moteur (21), ce qui est avantageux pour garantir qu'un moteur dans le compresseur se refroidit complètement, et permet un fonctionnement efficace et fiable.
