For example, Kaibu, Japanese Patent Publication No. 10-308482 C P U cooling structure provides high thermal conductivity. If the active heat sink and CPU meter use the above-mentioned "CPU cooling structure", a metal cooling guide with the required amount of deflection is held between the active heat sink = the surface of the CPU, thereby enabling the AHS fixing spring member to be fixed. The deformation amount of force σ is absorbed, and 'the month is enough to play enough'. However, the above-mentioned prior art

Page 11 200301855 V. Description of Invention (8) Fan. In addition, because it has a fanless structure, there is no noise generated by a forced air cooling fan. [Effects of the Invention] With the above configuration, the present invention has the following effects: (1) By using a heat pipe, it is only necessary to reserve a space for installing a heat absorption plate above a heat-generating component such as a CPU. Therefore, it is not necessary to install a conventional large-sized heat sink, and the space occupied by installing parts around the heating parts can be reduced. (2) The heat pipe is used for heat transfer, and a radiator integrated with a fan is used to cool the outside of the device, so that it can be reliably air-cooled outside the device. In a method in which a fan is cooled by contacting a heating component inside the device (currently the mainstream method), the exhaust gas after cooling is accumulated inside the device, causing the internal temperature of the device to rise. However, in addition to using the present invention, it can avoid The internal temperature of the device rises, and at the same time, the cooling effect of the heating element itself can be obtained. 〇 (3) By disposing the heat radiation part in the tube part, safety can be ensured, and at the same time, the smoke effect can be obtained. Even if the fan is at a low speed, the heat can be efficiently discharged to the outside. What's more, when the cooling effect can be obtained only by the chimney effect, the cooling can be performed only by the radiator, so the number of parts can be reduced and the quietness can be improved.
