Abstract: Embodiments of the invention provide a magnetron and a magnetron sputtering device, including an inner magnetic pole and an outer magnetic pole with opposite polarities. Both the inner magnetic pole and the outer magnetic pole comprise multiple spirals. The spirals of the outer magnetic pole surround the spirals of the inner magnetic pole, and a gap exists therebetween. In addition, the gap has different widths in different locations from a spiral center to an edge. Moreover, both the spirals of the outer magnetic pole and the spirals of the inner magnetic pole follow a polar equation: r=a?n+b(cos ?)m+c(tan ?)k+d, 0<=n<=2, 0<=m<=2, c=0 or k=0. Because the gap between the inner magnetic pole and the outer magnetic pole has the different widths in a spiral discrete direction, width sizes of the gap in the different locations can be changed to control magnetic field strength distribution in a plane, thus adjusting uniformity of a membrane thickness.

Abstract: An arc-shaped plate heat exchanger, including a cylindrical housing and a heat-exchanging plate assembly. The heat-exchanging plate assembly includes two groups of arc-shaped heat-exchanging plates symmetrically disposed at either side of the axis of the housing. In each group of the arc-shaped heat-exchanging plate, multiple arc-shaped heat-exchanging plates are arranged from the housing center outward and form isolating first and second fluid channels, the plates' diameters increasing outward. During heat exchange, cold fluid enters the heat exchanger from the housing's first fluid inlet, and flows through straight channels of the arc-shaped heat-exchanging plates to exit from a first fluid outlet, while the hot fluid enters the heat exchanger from a second fluid entrance on the side wall of the housing, and flows through arc-shaped channels of the arc-shaped heat-exchanging plates to exit from a second fluid outlet. Heat exchange between the cold and hot fluid is thus achieved.
