The heat pipe 16 heats the heat generated from the processor 15 to the apparatus main body 11 or when the docking station 13 is connected to the heat sink 21 through the spacer 17 from the heating surface (heated portion) of the heat pipe 16. It is an element that conducts heat to the heat receiving surface (heat receiving part).
The spacer 17 is a heat transfer member (Thermal Interface Material) interposed between the heat pipe 16 and the heat sink 1. The member is, for example, silicon rubber.

The opening 18 is a notch for allowing the heat sink 21 of the docking station 13 to be inserted into the apparatus main body 11 when the closed state is released (opened) by the opening / closing mechanism 19.
When the docking station 13 is to be connected (connected) to the apparatus main body 11, the opening / closing mechanism 19 shifts from the closed state to the opened state and receives the heat sink 21 into the apparatus main body 11. It is an opening / closing part for enabling heat conduction between the heat pipe 16 and the heat sink 21.
The external connection connector 20 is a connection element that connects an electrical terminal of the apparatus main body 11 and an electrical terminal of the docking station 13 corresponding to the electrical terminal, and has an external device connection detection pin. Has been.

The heat sink 21 is an element that absorbs heat when the docking station 13 is attached to the apparatus main body 11 and heat conduction to the heat pipe 16 in the apparatus main body 11 is enabled via the spacer 17. is there.
The air inlet 22 is an inlet that allows outside air to flow into the docking station 13. The fan 23 is a forced exhaust means that flows into the docking station 13 from the air inlet 22 and exhausts the air that has been transferred from the heat sink 21 and converted into hot air to the outside of the docking station 13.

The processor 15 communicates with the various electrical devices of the docking station 13 via the circuit formed on the substrate 14 and the external connection connector 20 as the processing target in the portable information processing device 10.

The information processing of the processor 15 and the communication method between the processor 15 and the docking station 13 are well known in this field and are not directly related to the present invention.
Various electrical devices of the docking station 13 include, for example, I / O connectors such as USB (Universal Serial Bus), PCMCIA (Personal Computer Memory Card International Association), LAN (Local Area Network), etc. And a storage device and the like.
Therefore, the portable information processing apparatus 10 is configured to be able to use an external device such as a mouse, a printer, a LAN, a disk device, and a storage device via the docking station 13.

Next, the operation of this embodiment will be described with reference to FIGS.
First, a state where the docking station 13 is not attached to the apparatus main body 11, that is, a case where the docking station 13 is used only by the portable information processing apparatus 10 will be described.
The portable information processing device 10 is activated by supplying power. During the operation, the portable information processing apparatus 10 monitors whether the docking station 13 is connected via the external device connection detection pin of the external connection connector 20. When it is detected that there is no connection, the processor 15 is operated with the frequency of the operation clock lowered. Thereby, the heat generation amount in the processor 15 is suppressed.

The cooling of the processor 15 in this operation state is performed by conducting heat to the apparatus main body 11 through the heat pipe 16 and naturally dissipating using the entire apparatus main body 11 as shown in FIG.
By such heat dissipation, the temperature rise of the processor 15 is suppressed within a predetermined operating temperature range, and normal operation of the processor 15 is ensured.

Next, the case where the portable information processing apparatus 10 is used in a state where the docking station 13 is mounted on the apparatus main body 11 will be described.
In this case, the connection of the docking station 13 is detected via the external device connection detection pin, and in response to this detection, the operation clock of the processor 15 is driven to the maximum frequency.

The heat that increases and cannot be dissipated by the above-mentioned natural radiation alone is generated by the heat sink 21 of the docking station 13 attached to the apparatus main body 11 via the spacer 17 from the heating surface of the heat pipe 16. Conducted (transmitted) to the heat receiving surface (FIG. 3) and dissipated into the air around the heat sink 21.
The air supplied around the heat sink 21 is low-temperature air that is forced to flow from the air inlet 22 by the fan 23. The air that has absorbed heat is exhausted out of the apparatus by the fan 23. The heat is exhausted by the intake and exhaust.
As is apparent from the above description, it is not necessary to limit the operation speed of the processor, and it is not necessary to increase the housing surface area and the weight in order to ensure the normal operation of the processor. That is, optimization of the processing speed and cooling performance of the apparatus can be achieved.

In addition to making heat conduction possible (through thermal connection), the main part of the docking station 13A is configured so as to be provided near the heat sink 51. This configuration is to cancel the necessity of conducting heat conduction by bringing the solid parts into contact with each other when the docking station 13A is connected to the apparatus main body 11A.
Since the configuration of the embodiment other than this configuration is the same as that of the first embodiment, the same components are denoted by the same reference numerals, and the description thereof is omitted.

Next, the operation of this embodiment will be described with reference to FIG.
The operation of this embodiment is the same as that of Embodiment 1 except that heat conduction from the apparatus main body 11A to the docking station 13A is performed by convection of the heat radiating portion 53 of the heat sink 51. That is, the fan 52 in the vicinity of the heat sink 51 more positively transfers heat to the air, creating an air flow as indicated by arrows in FIG. 5 and exhausting the air in the docking station 13A.

  Since the heat pipe 16 and the heat sink 51 are connected (coupled) through the spacer 17 so as to be able to conduct heat, the thermal conductivity is lowered due to poor contact between them, or the thermal conductivity due to contact deterioration between them. It helps to prevent a decrease in heat transfer caused by the decrease.

Next, the operation of this embodiment will be described with reference to FIG.
Exhaust heat to the outside of the heat generated in the apparatus main body 11 in this embodiment is performed via the exhaust heat system 65.
That is, the heat conducted from the apparatus main body 11 through the heat pipe 16 and the spacer 17 is transmitted to the refrigerant in the pipe 64 in the heat exchanger 61 of the exhaust heat system 65, and the refrigerant whose temperature has increased is pumped. It is circulated to the radiator 63 by 62. The heat accumulated in the refrigerant is radiated to the outside of the docking station 13B in the radiator 63, and the high-temperature refrigerant is cooled to become a low-temperature refrigerant.
The low-temperature refrigerant is circulated again to the heat exchanger 61 by the pump 62, and the above-described cooling cycle is repeated.
In this embodiment, since a refrigerant having a higher heat transfer rate than air is used, exhaust heat can be more efficiently performed.

  Thus, also in this embodiment, the effect to be obtained in the first embodiment can be obtained more efficiently.
