Abstract:
A scroll compressor comprises: a compression mechanism (CM), wherein the compression mechanism (CM) comprises a fixed scroll (22) and an orbiting scroll (24), the fixed scroll (22) comprises a fixed scroll end plate, a fixed scroll wrap, and a peripheral wall (S) located on a radial outer side of the fixed scroll wrap, and the orbiting scroll (24) comprises an orbiting scroll end plate (241), an orbiting scroll wrap, and a hub portion; and a main bearing seat, wherein a central through-hole of the main bearing seat communicates with the hub portion of the orbiting scroll to form a shaft cavity, the peripheral wall of the fixed scroll (22) makes contact with a first side surface of the orbiting scroll end plate (241) to form a contact portion, and an oil conveying path supplies lubricating oil in the shaft cavity to the contact portion and outputs the lubricating oil in the contact portion to the exterior of the compression mechanism. The scroll compressor improves lubrication performance of the supplied oil in the contact portion and heat dissipation performance of the compression mechanism, while also removing impurities in the contact portion.
