Abstract

A portable computer is provided to improve cooling efficiency by quickly discharging heat of a heat sink with forced convection, as surrounding air is flown by up/down reciprocal motion of an elevating member. The heat sink(60) is formed to a lower part of a keyboard and discharges the heat of an inner part of a main frame(30). The elevating member(70) generates an air flow to the heat sink by being formed to a central section of the keyboard and performing the up/down reciprocal motion. A driving part(80) ascends and descends the elevating member. The driving part includes a motor(82), an elevation supporter(84) supporting the elevating member, and a connector(86) connecting the motor and the elevation supporter.

The present invention relates to a portable computer, and more particularly to a portable computer with improved cooling efficiency.

As shown in FIG. 1, the conventional portable computer 1 includes a main body 30, a display unit 10 coupled to the main body 30 to form an image, a main body 30, and a display unit 10. ) Includes a hinge unit 20 for rotatably coupling.

As shown in FIG. 2, the body 30 accommodates a plurality of electronic components 50 that generate heat during operation. In addition, the main body 30 includes a keyboard 40 provided with a plurality of key buttons 42 and a heat dissipation member 60 coupled to the lower portion of the keyboard 40 to dissipate heat generated from the electronic component 50. It includes more. The main body 30 may further include a cooling fan (not shown) or a heat sink (not shown) to improve cooling efficiency.

The conventional portable computer has an effect of dissipating heat to the outside of the main body through a keyboard having a large area of heat of the heat dissipation member. However, it is difficult to effectively dissipate heat generated inside the main body only by natural convection through the keyboard without a separate cooling device.

It is therefore an object of the present invention to provide a portable computer with improved cooling efficiency.

The above object is, according to the present invention, a portable computer having a main body and a keyboard coupled to the main body, provided in the lower portion of the keyboard, the heat dissipation member for dissipating heat inside the main body; An elevating member provided to enable an elevating movement in one region of the keyboard to generate an air flow toward the heat radiating member; It is achieved by a portable computer comprising a drive for lifting the lifting member.

The driving unit may include a motor, an elevating support unit for elevating the elevating member, and a connecting unit connecting the motor and the elevating support unit.

Preferably, the elevating member is provided in the central area of the keyboard.

Hereinafter, a portable computer according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In addition, the same structure as the prior art will be described using the same reference numerals.

As shown in FIG. 1, the portable computer 1 of the present invention includes a display unit 10 for displaying an image, a main body 30 for supporting the display unit 10, and a display unit 10. And a hinge portion 20 rotatably connected to 30.

As shown in FIG. 3 and FIG. 4, a keyboard 40 having a plurality of key buttons 42 is coupled to the main body 30. The main body 30 accommodates a plurality of electronic components 50 that generate heat during operation. In addition, the main body 30 drives the heat dissipation member 60 for dissipating the electronic component 50, the elevating member 70 for dissipating heat transferred from the heat dissipation member 60, and the elevating member 70. The driving unit 80 further includes.

The keyboard 40 has a space in which the elevating member 70 to be described later will be mounted, and the key buttons 42 are divided into left and right. In the middle region of the keyboard 40, a space in which the elevating member 70 is mounted is formed.

The heat dissipation member 60 is provided in a plate shape in order to dissipate heat generated from the electronic component 50 in a short time. The heat dissipation member 60 is preferably made to correspond to the area of the keyboard 40 so as to contact the electronic component 50 to release the heat conducted from the electronic component 50 between the key button 42 of the keyboard 40. Do. The heat dissipation member 60 is provided with a penetrating portion so that the elevating support portion 84 to be described later is elevated. The heat dissipation member 60 may be made of aluminum or copper having good thermal conductivity. However, the heat dissipation member 60 may be provided as a heat sink or a graphite sheet. In addition, a separate heat transfer member may be added between the heat dissipation member 60 and the electronic component.

As shown in FIG. 3, the elevating member 70 is installed to be elevated in the central area of the keyboard 40. The elevating member 70 has a plate shape, and elevates to radiate heat conducted from the electronic component 50 to the heat radiating member 60 to generate a flow of air. That is, by the reciprocating motion of the elevating member 70 in the vertical direction, forced convection of the air around the elevating member 70 occurs to dissipate heat from the heat radiating member 60 into the air. Since the flow of ambient air occurs in accordance with the lifting movement of the lifting member 70, the heat of the heat dissipation member 60 can be easily released even in the space between the key buttons 42 of the keyboard 40.

The driving unit 80 connects the motor 82 for driving the elevating member 70, the elevating supporter 84 supporting the elevating member 70 to be elevated, and the motor 82 and the elevating supporter 84. It includes a connecting portion 86. The driving unit 80 may operate by the user's selection or automatically to elevate the elevating member 70.

The motor 82 is a general rotary small motor, in which the rotational motion of the motor 82 is converted into a linear motion by the connecting portion 86 and the elevating support portion 84 engaged with the teeth, thereby elevating the elevating member 70. Let's do it. The motor 82 may be used as long as it is a small motor that can be accommodated in the main body 30, including a step motor. As a result, as the lifting member 70 moves up and down, the ambient air flows, and the heat conducted from the electronic component 50 to the heat radiating member 60 can be easily radiated to the outside of the main body 30. As a result, the cooling efficiency is improved.

The lifting support 84 may be provided to support the center of the lifting member 70 at one point, or may be provided to support at two or more points.

In the portable computer according to an embodiment of the present invention having such a configuration, the operation process and the heat dissipation process of the elevating member will be briefly described as follows.

When heat is generated from the electronic component 50, the generated heat is conducted to the heat dissipation member 60. At this time, the drive unit 80 is operated by the user's selection or automatically. When the motor 82 rotates and the rotational motion of the motor 82 is converted into a linear motion by the connecting portion 86 and the lifting support 84, and then transferred to the lifting member 70, the lifting member 70 is repeatedly. To rise and fall.

The surrounding air flows by the vertical reciprocating motion of the elevating member 70, and the flow of air radiates heat of the heat radiating member to the outside of the main body 30. Since the heat of the heat radiation member 60 is quickly released into the air by forced convection, the cooling efficiency can be improved.

In the above-described embodiment, the elevating member is provided in the central area of the keyboard, but may be provided to be distributed in the central area and the left and right areas of the keyboard.

As described above, in the portable computer according to the embodiment of the present invention, the cooling efficiency can be improved.
