  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a view showing the back of a personal computer. In the figure, 10 is a personal computer body, 20 is a heat dissipation block, 21 and 22 are screws for crimping the heat dissipation block 20 to a heat block (not shown) of the personal computer body 10, and 23 is fixing the heat dissipation block 20 to the personal computer body 10. It is a key (key) to do. Reference numeral 2 denotes a security wire connected to the heat dissipation block 20 via a joint portion (not shown). The security wire 2 is made of a material having good heat conductivity, such as copper, in order to have a heat conduction effect.

  FIG. 2 is a sectional view showing an embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals. In the figure, 20 is a heat dissipation block attached to the back of the personal computer, and the heat dissipation block 20 and the security wire 2 are connected by a joint portion (not shown). Reference numeral 30 denotes a heat block on which a personal computer CPU is mounted and heat dissipation measures are taken. Since the CPU is composed of a very high density chip, it becomes very hot when it operates. Therefore, it is usually mounted on a heat block as shown in the figure. The heat dissipating block 20 is fitted with the heat block 30. A material having good thermal conductivity is used for the heat dissipation block 20 and the heat block 30. In general, copper is preferable, but aluminum is often used in terms of cost.

  In the heat dissipation block 20, 21 and 22 are screws and are provided at both ends of the heat dissipation block 20. Reference numeral 23 denotes a key for locking the heat dissipation block 20 to the heat block 30. Reference numeral 24 denotes a heat conductive rubber formed on the surface of the heat dissipation block 20.

  In the heat block 30, 31 and 32 are screw holes, and the screws 21 and 22 are rotationally inserted. Reference numeral 33 denotes a hole formed in the heat block 30. The hole 33 is provided for inserting the key 23 attached to the heat dissipation block 20. The operation of the apparatus configured as described above will be described as follows.

  In the state shown in FIG. 2, the heat dissipation block 20 is brought into contact with the heat block 30. As a result, the key 23 is inserted into the hole 33. When the knob 23a of the key 23 is slid sideways, the heat dissipation block 20 is locked to the heat block 30 and cannot be removed. When the screws 21 and 22 are turned in this state, the screws 21 and 22 are rotationally inserted into the screw holes 31 and 32. Finally, when the screws 21 and 22 are tightened, the heat dissipation block 20 is pressure-bonded to the heat block 30.

  At this time, since the heat dissipation block 20 and the heat block 30 are pressure-bonded via the heat conductive rubber 24, the heat generated in the heat block 30 is conducted to the heat dissipation block 20 via the heat conductive rubber 24. The heat conducted to the heat dissipation block 20 is transmitted to the security wire 2 and radiated. That is, the heat generated in the heat block 30 is transmitted to the heat radiating block 20 and is radiated by the heat radiating block 20 and the security wire 2.
