Title:
ROTOR HAVING COOLING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2021/112327
Kind Code:
A1
Abstract:
The present invention relates to a rotor having a cooling function and, more specifically, to a rotor having a cooling function for cooling down a friction area by circulating a supplied fluid in order to prevent a phenomenon in which, when a pump is driven, frictional heat is generated between a rotor and a side plate due to a high-speed rotation, and thus, the rotor breaks due to the frictional heat and the function of the pump is lost. According to the present invention, with regard to a rotor for a pump, rotary shafts are formed on opposite ends of a body, lobes are formed on the body at constant intervals, wherein the lobes have coating layers formed by coating the lobes with an elastic material, and the coating layers on a side surface of the body are provided with storage spaces formed for temporarily storing a supplied and discharged fluid. Each of the storage spaces is partitioned into two by a partition wall and has a flow path formed therein to be connected to the outside of the rotor.
