Description

  Embodiments described herein relate generally to an electronic apparatus including a heat pipe.

  Recent electronic devices incorporate high-power circuit components such as a CPU at a high density. Such circuit components such as semiconductor elements have a very high degree of integration and perform information processing at high speed, and thus generate a large amount of heat. For this reason, in electronic devices, a method for treating heat released from circuit components is important. A heat pipe is generally used as a structure for releasing heat generated from circuit components. The heat pipe sends heat generated in the circuit components to a heat radiating fin provided in the vicinity of the fan. The heat transmitted to the heat radiating fins by the heat pipe is discharged to the outside of the apparatus by the air blown from the fan.

The fixing portion 31 can be provided at a location 35 different from one circuit component. Thereby, damage to the first circuit component 25 and the printed circuit board 24 can be effectively prevented. Therefore, it is particularly useful when preparing a high-functional model and a low-priced model with one appearance. Furthermore, the heat pipe 27 and the connecting tool 53 can be used as common parts between a model with the second circuit component 52 and a model without the second circuit component 52, thereby reducing the manufacturing cost. it can.

  Further, the portable computer 11 includes a bracket 34 for fixing the fan unit 26 to the second end 27B of the heat pipe 27. According to this, the fan unit 26 and the second end portion 27B are integrated by the bracket 34, and the load of the fan unit 26 is also applied to the heat pipe 27.
