A heat-dissipating module includes a heat pipe and a heat-dissipating device. The heat pipe has a first end, a second end and a partition pipe section. The first end is connected to a first heat-generating component. The second end is connected to a second heat-generating component. The diameter of the partition pipe section is different from the diameter of the first end. The heat-dissipating device is disposed on the heat pipe and is located between the first end and the second end. The heat-dissipating device includes a first heat-dissipating part and a second heat-dissipating part. The first heat-dissipating part is located between the first end and the partition pipe section for dissipating heat generated by the first heat-generating component. The second heat-dissipating part is located between the second end and the partition pipe section for dissipating heat generated by the second heat-generating component.

A circuit board includes a substrate forming an opening, a first thermal module disposed on a first side of the substrate, a second thermal module disposed on a second side opposite to the first side of the substrate m, and a heat pipe installed on the substrate and passing through the opening. A first end of the heat pipe is connected to the first thermal module, and a second end of the heat pipe is connected to the second thermal module.

A thermal module adapted for a desktop personal computer is provided. The desktop personal computer comprises a housing, a power supply, and a motherboard, the power supply being located inside the housing, and including a fan having an outlet oriented toward an outside of the housing, and the motherboard being located inside the housing, and including thereon a plurality of electronic elements. The thermal module comprises a first heat sink, an adjustment device, a first heat pipe, a second heat sink, and a second heat pipe. The first heat sink is disposed on one of the electronic elements. The adjustment device is slidably and thermally connected to the first heat sink by the first heat pipe, and is slidably and thermally connected to the second heat sink, located outside the housing at the outlet of the fan, by the second heat pipe.

The invention discloses an air guide with at least one heat sink and at least one heat pipe. The heat pipe of the air guide can conduct the heat generated by a heat source to the heat sink of the air guide. The heat sink of the air guide increases the area of heat dissipation, and the distribution of the heat sink enables more blown-in air to carry the heat away. Accordingly, the air guide of the invention can increase the efficiency of heat dissipation within an electronic device.

A computer has a casing that accommodates a main board having a heat generating component that generates heat therein. The computer includes an internal heat discharging part disposed in the casing and coupled with the main board to discharge a first portion of the heat generated by the heat generating component, an external heat discharging part provided on an external surface of the casing to discharge a second portion of the heat generated by the heat generating component, and a heat transmission part to transmit the first and second portions of the heat generated by the heat generating component to the internal and the external heat discharging parts, respectively, such that the first and second portions of the heat generated from the heat generating component is discharged through the internal and the external heat discharging parts, respectively. Accordingly, the computer has a simple structure and assembly and an improved heat discharging efficiency.
