Abstract: A method of assembling a waterproof structure includes the following operations. Connect a first input/output connector of a circuit board to a first positioning fixture. A first elastic adhesive is combined with a first rigid board. An end of the first positioning fixture away from the first input/output connector is passed out of the first rigid board, and the first input/output connector and the first elastic adhesive are separated on two sides of the first rigid board. The circuit board is arranged in the casing, wherein the first positioning fixture is inserted from the first input/output opening on the first wall inside the casing, so that the first elastic adhesive adheres the first rigid board to the first wall of the casing, and the first elastic adhesive fills a spacing between the first positioning fixture and the first input/output opening.

Abstract: A fan includes a fan hub and a plurality of blades. At least one of the blades includes an axial blade portion and a centrifugal blade portion. The axial blade portion has an axial arc surface. The axial arc surface extends between opposite two edges of the at least one blade, and connects with one of the two edges. The centrifugal blade portion has a guide trench. The guide trench extends away from the centrifugal blade portion. A width of the guide trench increases as it extends away from the centrifugal blade portion.

Abstract: A fan impeller includes a wheel casing, a plurality of fan blades and a plurality of first wind-guiding structures. The wheel casing is configured to rotate about an axis. The fan blades surround the axis and are arranged in a radial form. Each of the fan blades includes an end edge and two extending edges. The end edge is away from the wheel casing. The extending edges connect between the end edge and the wheel casing. The end edge and the extending edges define a windward surface and a leeward surface opposite to each other. The first wind-guiding structures are respectively disposed on the leeward surface of the corresponding fan blade. Each of the first wind-guiding structures is at least partially adjacent with the end edge and one of the extending edges of the corresponding fan blade.

Abstract: An electronic apparatus includes a first housing, a second housing, a positioning structure, a hinge structure and a positioning piece. The positioning structure includes a plate, a pole and a first snapping portion. The pole and the first snapping portion connect the plate which connects the second housing. The hinge structure includes a first connecting portion and a second connecting portion. The first connecting portion connects the first housing. The second connecting portion pivotally connects the first connecting portion. The second connecting portion includes a main body, a second snapping portion and a hole. The second snapping portion connects the main body and snaps with the first snapping portion. The hole locates at the main body for the pole to penetrate through. The positioning piece locates in the hole and abuts against the main body. The positioning piece connects the pole.

Abstract: A detachable computer includes a host, an expansion base, a first latch structure and a second latch structure. The first and second latch structures are disposed on a back surface of the host and an engaging surface of an engaging plate of the engaging plate respectively. One of each pair of the first and second latch structures includes a clamp portion and another one includes a clip member. The host is engaged with the engaging plate by latching the clip member with the clamp portion. The clip member includes a frame and a clip column. The clip column extends from a first sidewall to a second sidewall of the frame. The clip member is latched into the clamp portion through the clip column. Two sides of the clamp portion substantially abut against the first and second sidewalls when the clip column is latched into the clamp portion.

Abstract: A cooling module for using in a metal housing of a calculation processing apparatus is disclosed. The cooling module is adapted to cool at least one heat source inside the metal housing. The cooling module comprises a first heat conduction plate, a second heat conduction plate and a heat conduction device, wherein the first heat conduction plate covers the heat source, the second heat conduction plate connects to the metal housing, and the heat conduction device is adapted to connect the first heat conduction plate with the second heat conduction plate. After the heat generated by the heat source is absorbed by the first heat conduction plate, the heat is transmitted to the second heat conduction plate through the heat conduction device, and will be dissipated uniformly throughout the metal housing.
