Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electronic device, and relates to a portable electronic device having improved heat radiation characteristics of a heat generating component.

[0002]

2. Description of the Related Art In recent years, as electronic devices have become smaller and lighter,
The demand for portability of electronic devices is increasing. In particular, electronic devices involving sound and images are often carried outdoors and used, and those having a network function are increasingly required to have higher performance.

On the other hand, multimedia electronic devices that handle audio and images are required to have higher processing speeds than conventional ones. Therefore, with the reduction in power consumption of electronic devices, higher functionality and higher density packaging are required. Is required.

[0004] For this reason, there have been major issues in miniaturization for improving portability and heat radiation processing to cope with an increase in heat generation due to higher performance.

In a conventional portable electronic device, a case is formed of a resin in order to reduce the weight and cost, but the heat radiation characteristic is small due to low thermal conductivity. For this reason, if the case is made of light metal such as magnesium or aluminum,
High heat dissipation due to high thermal conductivity.

[0006]

However, as the size of the portable electronic device is reduced, the surface area of the case is reduced, and the heat radiation characteristic is degraded due to the reduction of the heat radiation area.

On the other hand, provision of forced cooling means such as a fan or provision of a radiator such as a heat sink is not preferable because it is against the miniaturization of portable electronic equipment.

[0008] Therefore, an object of the present invention is to provide a portable electronic device which solves such a problem.

[0009]

According to a first aspect of the present invention, there is provided a portable electronic device comprising: a case attached to a belt for attachment to a human body; a heat radiation member provided on the belt; The portable electronic device according to claim 2, wherein the heat-generating component provided inside and the heat-dissipating member are connected via a heat-conducting member. Are provided along the line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a portable electronic device according to the present invention will be described below.

(A) First Embodiment As shown in FIG. 1, a portable electronic device 1 includes a main body 2 and a belt 3.
It is composed of As shown in FIG. 2, the main body 2 is configured by housing components mounted on the printed board 5 in a case 4 made of resin or a metal such as aluminum or magnesium. A heat-generating component 6 that generates a lot of heat and many other components are mounted on the printed board 5. Reference numeral 7 denotes a connector unit. A heat connecting portion 8 made of aluminum or magnesium is fixed to the outside of the case 4, and the heat connecting portion 8 and the heat generating component 6 are connected via a heat conductive film 9 as an auxiliary heat conductive member.

The belt 3 is a belt body 10 made of leather or the like.
And a heat conduction belt 11 or the like as a main heat conduction member embedded in the belt body 10. The heat conduction belt 11 is made of a high heat conduction film such as a carbon fiber type. Cutouts are formed at regular intervals in the belt main body 10, and the cutouts are provided with heat dissipating members 14 fixed to the heat conductive belt 11. In FIG. 1, reference numerals 3a and 3b denote detachable buckles.

The main body 2 is attached to the belt main body 10 and the heat conduction belt 11 as follows. A part of the belt main body 10 is cut out, and a heat connection part 13 made of aluminum or magnesium is fixed to the notched part. Cover 1 made of the same material as case 4
2 are formed with notches 12a at both ends.
In a state where the belt 3 is inserted through the portion a, the cover 12,
The belt main body 10, the heat conduction belt 11, the heat connection part 13, and the heat connection part 8 are connected by screws (not shown).

Next, the operation of the portable electronic device will be described. In order to attach the portable electronic device 1 to a human body, the pair of buckles 3a and 3b are cut off, the belt 3 is wound around the waist, and the pair of buckles 3a and 3b are joined again. When the main body 2 is operated, the heat-generating component 6 generates heat. This heat flows to the heat radiating member 14 via the heat conductive film 9, the heat connecting portions 8 and 13, and the heat conductive belt 11, and is released from the heat radiating member 14 to the atmosphere.

The heat conductive belt 11 is made of a carbon fiber type or other high heat conductive film and is therefore very lightweight. The heat dissipating member 14 can also be made lighter by using a light metal such as aluminum or magnesium.

(B) Second Embodiment FIG. 3 shows a second embodiment of a portable electronic device. This is a configuration in which the first embodiment is mounted on the waist, whereas the first embodiment is mounted on the shoulder.

The other configuration and operation are the same as those of the first embodiment, and the description is omitted.

In the first and second embodiments, a plurality of heat dissipating members are provided along the length direction of the belt. However, a single heat dissipating member may be used when the heat generation amount of the heat generating component is small. Further, the heat conduction belt itself can be used as a heat dissipation member.

[0019]

As can be seen from the above description, according to the portable electronic device of the first and second aspects, the heat generated by the heat-generating components in the case is guided to the heat-dissipating member of the belt via the heat-conducting member to dissipate heat. Since the heat is dissipated from the member, the heat dissipation characteristics are high.

Since the heat radiating portion occupying a large space has been moved onto the belt, the size of the main body including the case can be further reduced.
