Description

Technology Field

[0001] The present invention relates to a laptop computer stand using a thermoelectric element. More specifically, the invention relates to a laptop computer stand using a thermoelectric element that can support a laptop computer, generates electricity using heat generated from the laptop computer without a separate external power supply, performs various tasks such as operating a cooling fan and charging a separate external device using the generated electricity, is excellent in terms of energy efficiency, and offers excellent convenience of use by enabling free use and cooling performance even in spaces where power supply is impossible. Background Technology

[0002] A notebook computer refers to a computer manufactured by reducing its size to that of a notebook so that individuals can carry and use it. Due to its design characteristics, such notebook computers are configured to allow users to perform various tasks, such as document creation and information input / output, anytime and anywhere as needed while on the go.

[0003] Laptop computers generate significant heat during the process of handling tasks, which can lead to performance degradation or overheating issues when used for extended periods. In particular, if a laptop computer is placed on a flammable material such as fabric and used for a long time, there are problems such as an increased risk of fire on the flammable material due to the heat generated by the laptop.

[0004] To prevent such problems, laptop stands are widely used.

[0005] While commonly used laptop stands serve the function of stably supporting a laptop, most focus solely on the role of simply securing the computer. Additionally, these stands are typically designed to help organize the user's workspace or facilitate more convenient use of the laptop.

[0006] In other words, most conventional laptop stands simply support the laptop and feature structures designed to enhance user convenience, such as angle adjustment, while completely lacking any design to address the laptop's heat generation issues.

[0007] In order to perform cooling functions for a laptop computer mounted on a laptop stand, a separate external cooling fan or cooling pad must be used. Since these devices cause additional power consumption, they are not only very disadvantageous in terms of energy efficiency but also difficult to use in places where power supply is unavailable. In addition, there are problems such as reduced user convenience due to occupying a large amount of additional space. Prior art literature

[0031] FIG. 1 is a schematic perspective view illustrating the shape of a laptop computer stand using a thermoelectric element according to one embodiment of the present invention, FIG. 2 is a cross-sectional view taken along the line "AA" of FIG. 1 to explain the internal structure of a laptop computer stand using a thermoelectric element according to one embodiment of the present invention, and FIG. 3 is a drawing illustrating the structure of a blower guide pipe and an auxiliary fan according to one embodiment of the present invention.

[0032] A laptop computer mounting device using a thermoelectric element according to one embodiment of the present invention is configured to mount a laptop computer (10) and to recover heat energy generated from the laptop computer (10) to perform a cooling function for the laptop computer (10), and comprises a support plate (100), a thermoelectric element (300), and a cooling fan (400).

[0033] The support plate (100) is formed in a flat shape so that a laptop computer (10) can be mounted on its upper surface. A locking projection (120) is formed on one end of the support plate (100) to lock and support the mounted laptop computer (10).

[0034] One end of the support plate (100) is rotatably coupled to a separate base frame (200) around a hinge axis (110). An angle adjustment member (130) is rotatably coupled to one side of the lower surface of the support plate (100), and a plurality of angle adjustment grooves (210) are formed on the upper surface of the base frame (200) so that the angle adjustment member (130) can be inserted and engaged. The angle adjustment member (130) is inserted and engaged in one of the plurality of angle adjustment grooves (210), and the support plate (100) is fixedly supported at a specific angle of inclination. By adjusting the insertion position of the angle adjustment member (130) into the angle adjustment groove (210), the angle of inclination of the support plate (100) can be adjusted.

[0035] The shapes of the support plate (100) and base frame (200) are exemplary and can be changed to various shapes capable of supporting a notebook computer (10).

[0036] The thermoelectric element (300) is mounted on the upper surface of the support plate (100) and generates electricity by receiving heat generated from the laptop computer (10) mounted on the support plate (100).

[0037] Looking more specifically at this thermoelectric element (300), when an electric current is passed between two different conductive materials, a phenomenon occurs in which a temperature difference persists at both ends of multiple layers of conductive material; this is called the Peltier effect, and a device utilizing the Peltier effect is called a Peltier device. A Peltier device is a representative thermoelectric device. This thermoelectric element (300) is formed by alternately arranging N-type and P-type semiconductor devices between two insulating substrates, such as ceramic, like a sandwich, and an electrode plate is placed on the outer surface of the ceramic substrate, and the electrode plate is connected to the semiconductor devices. When an electric current is applied to one of the two substrates, one ceramic plate becomes cold and the opposite ceramic plate becomes hot according to the flow of the current. If the direction of the current is reversed, the cooling and heating are switched in the opposite direction. Meanwhile, conversely, if heat is applied to one of the substrates of the thermoelectric element (300), electricity is generated by the Seebeck effect, which is the opposite effect of the Peltier effect.

[0038] These thermoelectric elements (300) can generate electricity using the Seebeck effect or the Peltier effect, or be used as a cooling device.

[0039] In one embodiment of the present invention, a Peltier element is applied as a thermoelectric element (300), and as shown in FIG. 1, it can be formed in the shape of a flat plate that is long in one direction. A plurality of such thermoelectric elements (300) can be arranged in the center of the support plate (100).

[0040] According to this structure, when a laptop computer (10) is mounted on the upper surface of a support plate (100), the lower surface of the laptop computer (10) comes into contact with the upper surface of a thermoelectric element (300). Even if the lower surface of the laptop computer (10) does not come into contact with the thermoelectric element (300), it is positioned very close to it, so that heat generated from the laptop computer (10) is directly transferred to the upper surface of the thermoelectric element (300).

[0041] Therefore, since heat generated from the notebook computer (10) is transferred to the upper surface of the thermoelectric element (300), the thermoelectric element (300) generates electricity by the Seebeck effect.

[0042] Additionally, the thermoelectric element (300) is mounted so that its upper surface is exposed to the upper surface of the support plate (100) to facilitate heat transfer from the notebook computer (10). At this time, a separate thermal conductive pad (320) may be attached to the upper surface of the thermoelectric element (300) to improve the heat transfer rate. The thermal conductive pad (320) may be formed in the shape of a flat plate made of a material with excellent thermal conductivity, for example, an aluminum pad may be applied. During the process of attaching the thermal conductive pad (320) to the upper surface of the thermoelectric element (300), a thermally conductive adhesive (310) may be applied to the upper surface of the thermoelectric element (300). Since the thermal conductive pad (320) comes into contact with the thermoelectric element (300) over the entire area through the thermally conductive adhesive (310), the heat transfer rate is improved, and accordingly, heat generated from the notebook computer (10) can be transferred to the thermoelectric element (300) with higher efficiency.

[0043] According to this structure, heat generated from the notebook computer (10) is transferred to the thermoelectric element (300) in a form that minimizes external emission, and accordingly, the performance of the thermoelectric element (300) is improved and the amount of electricity generated is also increased.

[0044] The cooling fan (400) is positioned at the bottom of the support plate (100) and operates by receiving electricity generated by the thermoelectric element (300) to blow air. Although not illustrated, the cooling fan (400) and the thermoelectric element (300) may be connected via a wire.

[0045] As shown in FIG. 2, the cooling fan (400) is coupled to the lower surface of the support plate (100) and blows air toward the support plate (100). At this time, a plurality of blower holes (101) are formed in the support plate (100) to allow the air blown by the cooling fan (400) to pass through. Additionally, a cooling hole (102) having an opening larger than the blower hole (101) may be formed through the lower surface of the support plate (100) in the area where the thermoelectric element (300) is placed. Since the blower hole (101) penetrates the support plate (100), the air blown by the cooling fan (400) passes upward through the blower hole (101) and proceeds to the upper space of the support plate (100), and is delivered to the laptop computer (10) mounted on the upper surface of the support plate (100) to directly cool the laptop computer (10). Since the cooling hole (102) is formed through the lower surface of the thermoelectric element (300), air blown by the cooling fan (400) passes upward through the cooling hole (102) and is delivered to the lower surface of the thermoelectric element (300), thereby cooling the lower surface of the thermoelectric element (300). As the lower surface of the thermoelectric element (300) is cooled in this way, the temperature difference between the upper surface and the lower surface of the thermoelectric element (300) increases, and accordingly, the amount of electricity generated also increases.

[0046] In this way, by forming a blower hole (101) and a cooling hole (102) in the support plate (100), the laptop computer (10) can be cooled by the operation of the cooling fan (400) and the thermoelectric element (300) can be cooled at the same time, thereby increasing the efficiency and amount of electricity generated by the thermoelectric element (300).

[0047] Meanwhile, as shown in FIGS. 1 and 2, a blower guide pipe (500) is connected to one end of the lower surface of the support plate (100), and an auxiliary fan (520) can be installed on both ends of the blower guide pipe (500) to operate by receiving electricity generated by a thermoelectric element (300) and blow air towards the center along the blower guide pipe (500).

[0048] As shown in FIG. 3, a guide hole (510) may be formed in the center of the air blower guide pipe (500) to guide the air blown by the auxiliary fan (520) to flow along the lower surface of the support plate (100).

[0049] According to this structure, when the auxiliary fan (520) operates, external air flows towards the center along the air blower guide pipe (500) and flows along the lower surface of the support plate (100) through the guide hole (510). The air flowing along the lower surface of the support plate (100) can cool the lower surface of the support plate (100), thereby indirectly cooling the lower surface of the thermoelectric element (300). Additionally, the air flowing along the lower surface of the support plate (100) can be delivered to the lower surface of the thermoelectric element (300) through the cooling hole (102), thereby additionally cooling the lower surface of the thermoelectric element (300).

[0050] In this way, by additionally cooling the lower surface of the thermoelectric element (300) through the blower induction pipe (500) and auxiliary fan (520), the efficiency and amount of electricity generated by the thermoelectric element (300) can be increased.

[0051] As described above, a laptop computer stand according to one embodiment of the present invention can cool the laptop computer (10) by generating electricity using heat generated from the laptop computer (10) and operating a cooling fan (400) using the generated electricity, and can enable stable use without overheating problems even when the laptop computer is used for a long time. In particular, by generating electricity using heat generated from the laptop computer (10) without a separate power supply, it is excellent in terms of energy efficiency and allows for free use and performance even in spaces where power supply is impossible.

[0052] Meanwhile, a battery (600) capable of receiving and charging electricity generated by a thermoelectric element (300) may be coupled to the support plate (100). The battery (600) may be detachably coupled to the lower surface of the support plate (100) and may be utilized as an auxiliary battery for electronic devices, etc., depending on the user's needs. Additionally, electricity generated from the thermoelectric element (300) can be stored by charging the battery (600), and the power from the battery (600) can be utilized in various ways.

[0053] Additionally, as shown in FIG. 4, a charging port (220) is formed in the base frame (200) to connect an external device, and electricity generated by a thermoelectric element (300) can be supplied to the charging port (220) to charge the external device connected to the charging port (220). Electricity generated by the thermoelectric element (300) may be supplied directly to the charging port (220), but it may also be configured to supply electricity charged in a battery (600).

[0054] External devices, such as smartphones, can be connected to the charging port (220) to charge them. Additionally, a separate wireless charger (230) can be connected to the charging port (220), and the wireless charger (230) can be used to wirelessly charge external devices, such as smartphones. The wireless charger (230) may be formed to be detachable or attached to the charging port (220), but it may also be formed to be integrally connected to the base frame (200).
