Abstract: A fin is penetrated through by a heat pipe. The fin includes a fin body and a plurality of positioning protrusions. The fin body has an accommodating hole penetrated by the heat pipe. The positioning protrusions are formed at the circumference of the accommodating hole for holding against the heat pipe, so that a gap is provided between the heat pipe and the circumference of the accommodating hole.

Abstract: A heat dissipation module including a fan and a first heat dissipation unit is provided. The fan has a frame and a blade set provided in the frame. The frame has an air inlet and an air outlet, and a flow channel communicating the air inlet and the air outlet is formed between the blade set and the frame. The first heat dissipation unit includes a first heat dissipation base, a first radiating fin assembly located inside the frame wall of the fan on the flow channel, and a first heat pipe which is connected between the first heat dissipation base and the first radiating fin assembly.

Abstract: A fluid-providing module including a housing and a fan is provided. The housing includes a first inlet and a space connected to the first inlet. The space includes a first channel and a second channel such that one is stacked on top of the other. The first channel includes a first outlet and the second channel includes a second outlet. The fan is disposed in the space for moving the fluid and discharging the fluid from the housing through the first outlet and the second outlet. Consequently, the fluid-providing module can discharge the fluid in multiple directions. In addition, an electronic device using the fluid-providing module is also provided.

Abstract: A duct flow-type fan comprised of a housing having at least one upper and one lower side walls as well as a laterally oriented air port, a motor, a vane, and a shaft. The vane is fitted onto one end of the shaft, with the other end of the shaft conjoined to and driven by the motor such that vane air current passes through the laterally oriented air port of the housing to cool the heat sink of a computer chip in order to achieve efficient computer chip heat dissipation.
