Abstract: A support device for heat dissipation module provides a frame with four corners thereof extending outward a support part respectively. A mounting opening is disposed at the central area of the frame with two opposite side of the mounting opening having a projection plate respectively. A facial side of the projection plate is provided with fitting pins to fit with a guide heat plate and covering the mounting opening without help of welding. Therefore, thinner guide heat plate can be used for simplifying manufacturing process and lowering production cost.

Abstract: A method for a surface being plated locally includes a fixture for holding at least a work piece and the fixture is supported with two opposite lateral walls of a plating tank. Hence, a plated zone on a surface of the work piece can be immerged into the liquid contained in the plating tank for the plated zone being coated with de-oxide layer and plating layer sequentially.

Abstract: A fan with supercharging device has a hub and fan blades. A hub has a shape similar to a cone with a tip end and a circumferential side. The fan blades extend radially from the circumferential side of the hub. Each of the fan blades has a joining end being attached to the circumferential side, a free end extending outward the hub and a front edge and a rear edge being between the joining end and the free end respectively. The rear edge of the respective fan blade is shielded by the front edge of another fan blade next to it. The unshielded portion of the respective fan blade has an area gradually increases from the joining end to the free end. A projection is disposed at the free end along a direction of fluid flow. Hence, fluid pressure is capable of increasing significantly while the fan is in operation.

Abstract: A fan capable of increasing pressure of fluid provides a hub and fan blades. The hub has a flat facial end and a circumferential side. The fan blades extend radially from the circumferential side of the hub. Each of the fan blades has a joining end being attached to the circumferential side and a free end extending outward the hub and a front edge and a rear edge being between the joining end and the free end. The rear edge of the respective fan blade is shielded by the front edge of another fan blade next to it and the unshielded portion of the respective fan blade has an area gradually increases from the joining end to the free end such that the pressure of fluid at the free end is greater than that at the joining end.
