In this case, the screw is fastened to the bottom case 20 together with the mounting bracket 37 mounted on the outer surface of the hard disk drive 36.

In addition, an auxiliary substrate 40 is installed on an upper surface of the bottom case 20 corresponding to the hard disk seat 30. The auxiliary substrate 40 is installed to allow the guide rib 34 to be inserted into the guide hole 42. In other words, the guide rib 34 guides the mounting position of the auxiliary substrate 40 and prevents the guide rib 34 from being arbitrarily flown in the mounted state. The auxiliary substrate 40 may be fastened to the bottom case 20 by using a separate screw.

In addition, when the keyboard deck 45 is fastened to the bottom case 20, the upper end of the guide rib 34 supports the lower surface of the keyboard deck 45. That is, the guide rib 34 supports the lower surface of the armrest 47. By doing so, the area of the armrest 47 and the keyboard deck 45 can be supported without sagging.

When the portable computer is used in the state where the hard disk drive 36 is mounted as described above, the heat radiating fan unit 29 is operated. As the heat radiating fan unit 29 is operated, air flow is formed in the main body. The air flow enters the air outside the main body to the inside, and receives heat from the main body to be discharged to the outside through the outlet 29 '.

On the other hand, the outside air is introduced into the main body by the airflow formed by the heat dissipation fan unit 29 through the vent hole 21. Some of the air introduced into the air through the vent hole 21 enters the hard disk seat 30 through the communication slot 35. The rest of the air is moved along the upper surface of the bottom case 20 corresponding to the outside of the hard disk seat 30, passing through the through portion (32).

As such, the air passing through the inside of the hard disk seat 30 and the through part 32 receives heat generated from the hard disk drive 36. Then, the air enters the heat dissipation fan unit 29 as indicated by the arrow in FIG. 4, and is discharged to the outside through the discharge port 29 ′ by the heat dissipation fan unit 29.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

For example, in the accompanying embodiment, a configuration having all the various features is illustrated, but for example, the through part 32 is formed, but the guide rib 34 may be formed without the shape. Although 320 is formed, it is possible to have a shape without the communication slot 35.

In the hard disk drive mounting structure of the portable computer according to the present invention as described in detail above, the following effects can be obtained.

First, in the present invention, through-holes and communication slots communicating with the inside of the main body are formed in the hard disk mounting part on which the hard disk drive is mounted so that air can flow therebetween. Therefore, the heat dissipation of the hard disk drive seated on the hard disk mounting portion can be more efficient. In particular, by forming a ventilation hole through which the outside air can be introduced at a position corresponding to the communication slot, the air flow is formed by the heat radiating fan unit can be more effectively radiated.

In the present invention, guide ribs are formed at the edges of the penetrating portion communicating with the inside of the hard disk seat and the main body, and the guide ribs support the armrests of the keyboard deck, thereby reinforcing the strength of the armrests more accurately than the keyboard deck. . Therefore, even if the user puts his hand on the armrest, the armrest may be kept flat without being pressed.

In the present invention, the guide rib formed at the edge of the through part serves as a guide for installing the auxiliary substrate. That is, the guide rib is inserted into the guide hole of the sub-board to guide the position where the sub-board is installed and to make the sub-board firmly mounted, so that the sub-board can be mounted more firmly and accurately.

In addition, by forming a penetrating portion that communicates with the inside of the hard disk seating portion and the main body portion, the amount of material forming the bottom case is reduced by that amount, which lowers the manufacturing cost and reduces the weight of the bottom case, thereby reducing the weight of the portable computer. There is also.
