As shown in FIG. 2, the ridge portion 14 is formed over the entire left-right direction of 12a (in this embodiment, the upper direction in FIG. 2 is the left direction, and the lower direction is the right direction). The entire front end face of the notebook PC 13 is uniformly supported. In this embodiment, the device main body 12 and the ridge portion 14 are integrally formed from the same stone.

A plurality of (seven in this embodiment) grooves 15 are formed on the support surface 12a substantially in parallel with the ridges 14.
The surface area has been increased. On both left and right sides of the apparatus main body 12, grip portions 16 are integrally formed so as to be parallel to the support surface 12a, and the support surface 12a and the upper surface of the grip portion 16 are flush with each other. A plurality (five in the present embodiment) of grooves 17 extending in the front-rear direction from the rear end to the center is formed on the lower surface 12b of the apparatus main body 12, and the end of the groove 17 on the side of the center is formed. Is rounded. Due to the groove 17, the lower surface 12b
The surface area has been increased.

Here, the apparatus main body 12 and the ridges 14
A stone material that can be used as a material for the above will be described. That is, as the natural stone, for example, Bianco Carrara,
Marble such as chaseden, and suede rose

This is data obtained by conducting a test based on the S standard. The apparent specific gravity, the water absorption and the compressive strength are JIS-A-5003, the bending strength is JIS-A-5411, and the hardness is JIS-Z-22.
The data is based on the standard No. 46.

Next, the operation of the heat radiating device 11 of the present embodiment configured as described above will be described. First, the device main body 12 of the heat radiating device 11 is placed on a table or the like, and the device main body 1
The notebook PC 13 is placed on the second support surface 12a. Then, since the support surface 12a is lower toward the front side,
A force is applied to the notebook PC 13 to slide the notebook PC 13 forward on the support surface 12a. However, the movement of the notebook PC 13 in the sliding direction is restricted by engaging with the ridge 14.

The operating heat generated from the notebook PC 13 placed on the supporting surface 12a of the heat radiating device 11, especially the operating heat generated from the lower surface of the notebook PC 13, is transferred to the supporting surface 12a and the surface of the groove 15. It is. At this time, even if the operating heat is rapidly transmitted from the notebook PC 13 to the support surface 12a and the groove 15, the device body 12 made of stone hardly undergoes thermal deformation as compared with a metal such as aluminum, and the notebook PC 13 is supported. It is stably supported by the surface 12a.

The heat transmitted to the support surface 12a and the groove 15 is absorbed into the apparatus main body 12, and is radiated through the lower surface 12b of the apparatus main body 12, the groove 17 of the lower surface 12b, and the side surface of the apparatus main body 12. You. Usually, the thermal conductivity of stone is smaller than that of metals such as aluminum. Therefore, the device main body 12 does not suddenly release the operating heat absorbed from the radiator 11 to the outside, and the influence of the heat on the periphery of the radiator 11 is small.

The vibration generated during operation generated from the notebook PC 13 is attenuated by the apparatus main body 12 and the ridges 14 made of a natural stone having a large number of fine holes. Propagation of vibration is suppressed. In addition, the operating sound generated from the notebook PC 13 is also absorbed by the apparatus main body 12 and the ridge 14.

In addition, the stone material has a lower thermal conductivity than a metal such as aluminum, for example, so that the influence of heat from the heat radiating device 11 to the surroundings can be reduced and the stone material can sufficiently exhibit an endothermic effect.

(2) In this embodiment, although the heat radiating device 11 is made of a single material, the notebook PC 1
A plurality of effects, such as a heat absorbing effect of sufficiently absorbing the heat generated from 3, a vibration damping effect of attenuating vibration, and a sound absorbing effect of absorbing operation noise, can be achieved with a simple configuration.
