Description

Technical Field

[0001] This utility model relates to the field of computer-aided heat dissipation technology, and in particular to a portable computer heat dissipation device. Background Technology

[0002] Portable computers (such as laptops and tablets) are widely used in office, study, and outdoor work scenarios due to their portability. However, their internal components are highly integrated and their heat dissipation space is limited. When running for a long time (such as running large software or multitasking), heat is easily accumulated, causing the machine to overheat, its performance to drop, and even shortening the lifespan of the hardware. Therefore, it is necessary to equip them with corresponding heat dissipation devices with support functions.

[0003] Current laptop coolers mainly consist of a support base and a cooling fan. To ensure stable support for the laptop, the support surface of the support base is usually larger than the bottom of the laptop. Furthermore, since most existing support bases adopt an integrated design, they take up a lot of space and are inconvenient to carry.

[0004] An existing patent (publication number: CN221101359U) discloses a portable computer heat dissipation device. This utility model is an assembly type. When carrying the device, the space occupied by the device can be reduced by disassembling the device, making the device easier to carry. When assembling the device, you only need to connect the two sets of placement strips and insert them into the heat dissipation mechanism to complete the assembly. Disassembly can be completed by reversing the steps. It is easy to assemble and disassemble and easy to use.

[0005] To address the aforementioned issues, existing patents have provided solutions, but existing portable computer cooling devices suffer from core problems: they are mostly fixed, integrated structures, resulting in large size and poor portability when stored, making it difficult to meet the needs of mobile scenarios such as outdoor office work. In addition, the cooling components are mostly fixed installations, and after long-term use, dust accumulates on the filter and the fan needs to be completely disassembled for maintenance, which is cumbersome. Furthermore, they lack a design for quick deployment and efficient heat dissipation, failing to balance portability and immediate use needs.

[0006] Therefore, a portable computer cooling device is proposed. Utility Model Content

At the same time, the cooling components are mostly fixed installations, and after long-term use, the filter will accumulate dust and the fan will need to be completely disassembled for maintenance, which is cumbersome. Furthermore, they lack a design for quick unfolding support and efficient heat dissipation, and cannot take into account both portability and the need for immediate use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A portable computer heat dissipation device includes a left support plate 1 and a right support plate 2. The front and rear sides of the inner sides of the left support plate 1 and the right support plate 2 are provided with portable turning structures 3. The top of the left support plate 1 and the right support plate 2 are provided with heat dissipation structures 4. The rear side of the bottom of the left support plate 1 and the right support plate 2 are provided with folding diagonal bracing structures 5. The front side of the top of the left support plate 1 and the right support plate 2 is provided with folding machine blocking structures 6.

[0030] The portable turning structure 3 includes a hidden groove 31, which is opened on the front and rear sides of the left support plate 1 and the right support plate 2. The inner side of the hidden groove 31 is provided with a threaded hole 32. A central rotating bushing 33 is provided inside the hidden groove 31. Threaded shafts 34 are rotatably connected to both sides inside the central rotating bushing 33. The inner side of the threaded shafts 34 is threaded into the inside of the threaded hole 32.

[0031] In this embodiment: by setting a left support plate 1, a right support plate 2, a portable turning structure 3, a heat dissipation structure 4, a folding diagonal brace structure 5, and a folding blocking structure 6, the device achieves flexible storage, stable support, and efficient heat dissipation. In use, first adjust the state of the left support plate 1 and the right support plate 2 using the portable turning structure 3: hold the left support plate 1 and the right support plate 2 with both hands and rotate them in opposite directions. At this time, the central rotating bushing 33 located in the hidden groove 31 remains fixed. The threaded shafts 34 connected to the threaded holes 32 in the hidden groove 31 of the left support plate 1 and the right support plate 2 will rotate synchronously inside the central rotating bushing 33. Because the threaded shafts 34 on both sides are threadedly engaged with the threaded holes 32 of the left support plate 1 and the right support plate 2 respectively, the left support plate 1 and the right support plate 2 can be easily unfolded or disassembled during rotation. When combined and unfolded, it forms a flat support surface suitable for placing a laptop. When folded, it significantly reduces the overall size, making it easy to carry and store. Next, it prepares for placing the computer: unfold the folding diagonal support structure 5 on the bottom rear side of the left support plate 1 and the right support plate 2 outward to form a stable diagonal support. Adjust it to a comfortable tilt angle according to usage habits. At the same time, unfold the folding blocking structure 6 on the top front side of the left support plate 1 and the right support plate 2 upward to make it stand up and block and limit the front of the laptop, preventing the computer from sliding during subsequent use. The whole process, through the coordinated cooperation of various structures, realizes the functions of flexible folding and storage, quick unfolding support, stable placement of the computer, and convenient maintenance of heat dissipation components, adapting to the needs of various usage scenarios.

[0032] Specifically, such as Figure 3 As shown, the heat dissipation structure 4 includes a base plate 41 embedded inside the left support plate 1 and the right support plate 2. The top and bottom front and rear sides of the base plate 41 are each embedded with a first magnetic sheet 42. A cooling fan 43 is provided inside the base plate 41. The cooling fan 43 is connected to a USB cable. A partition plate 44 is provided at the top and bottom of the base plate 41.

[0033] Specifically, such as Figure 3 As shown, magnet pieces 45 are embedded in the front and rear sides of the top of the partition 44, and the magnet pieces 45 are magnetically connected to the first magnetic piece 42.

[0034] Specifically, such as Figure 3 As shown, a dustproof mesh 46 is embedded in the top of the partition 44. The dustproof mesh 46 is located outside the cooling fan 43. The top of the left support plate 1 and the right support plate 2 are both provided with top pads 47. The front and rear sides of the bottom of the top pad 47 are embedded with second magnetic pieces 48. The second magnetic pieces 48 are magnetically connected to the magnetic pieces 45. A flat mesh 49 is embedded in the top of the top pad 47. The flat mesh 49 is located on top of the dustproof mesh 46.

[0035] In this embodiment: By setting up a heat dissipation structure 4, during assembly, the base plate 41 is embedded inside the left support plate 1 and the right support plate 2. The first magnetic pieces 42 at the top and bottom of the base plate 41 can be magnetically attracted to the magnetic pieces 45 at the bottom of the partition plate 44 and the second magnetic pieces 48 at the bottom of the top pad 47, respectively, to quickly complete the assembly. When in use, the cooling fan 43 is connected to the computer via a USB cable for power supply and startup. Cold air passes through the dustproof mesh 46 (blocking dust from entering) at the top of the partition plate 44 and acts on the bottom of the laptop computer through the flat mesh 49, accelerating heat dissipation. The flat mesh 49 can also prevent the bottom of the computer from directly blocking the dustproof mesh 46 and affecting air intake. When it is necessary to clean the dustproof mesh 46 or maintain the cooling fan 43, it is only necessary to separate the magnetically connected top pad 47 and partition plate 44 to remove the dustproof mesh 46 for cleaning, or to remove the partition plate 44 to maintain the cooling fan 43. There is no need to disassemble the main support plate, making the operation convenient and not affecting the overall structure of the device.

[0036] Specifically, such as Figure 5 As shown, the folding brace structure 5 includes a receiving groove 51 opened at the bottom of the left support plate 1 and the right support plate 2, and a torsion spring shaft 52 is rotatably connected to the rear side inside the receiving groove 51.

[0037] Specifically, such as Figure 5 As shown, a diagonal support rod 53 is fixedly connected to the front side of the torsion spring shaft 52, and the diagonal support rod 53 is located at the bottom of the receiving groove 51.

[0038] In this embodiment: by setting up a folding brace structure 5, the receiving grooves 51 at the bottom of the left support plate 1 and the right support plate 2 provide storage space for the inclined support rod 53. When not in use, the inclined support rod 53 can be folded up against the inner wall of the receiving groove 51 to reduce the volume occupied by the device. When support is needed, the inclined support rod 53 is pulled outward, and it rotates in the receiving groove 51 through the torsion spring shaft 52. The torsion spring characteristics of the torsion spring shaft 52 can provide stable elasticity during rotation, preventing the inclined support rod 53 from swaying randomly. At the same time, it can stay at a suitable angle as needed to form a stable inclined support, which is suitable for the use of laptop computers placed at an angle. After the support is completed, pressing the inclined support rod 53 inward will make it rotate back to the receiving groove 51 along the torsion spring shaft 52. The operation is simple and quick.

[0039] Specifically, such as Figure 6 As shown, the folding baffle structure 6 includes a groove 61 opened on the front side of the top of the left support plate 1 and the right support plate 2, and a baffle plate 62 is rotatably connected to the front side inside the groove 61.

[0040] Specifically, such as Figure 6 As shown, an anti-slip buffer pad 63 is adhered to the bottom of the baffle plate 62. The anti-slip buffer pad 63 is made of rubber material.

[0041] In this embodiment: By setting a folding baffle structure 6, the groove 61 on the front side of the top of the left support plate 1 and the right support plate 2 can accommodate the baffle plate 62. When not in use, the baffle plate 62 fits against the inner wall of the groove 61, without affecting the placement of the computer and the storage of the device. When in use, the baffle plate 62 is rotated upward to make it stand up, which can block the front of the laptop computer placed on the top of the left support plate 1 and the right support plate 2, preventing the computer from sliding forward due to tilting or collision. At the same time, the rubber anti-slip buffer pad 63 at the bottom of the baffle plate 62 can increase the friction with the front of the computer, further improving the limiting stability, and can also prevent the hard baffle plate 62 from directly contacting the computer shell and causing scratches, thus playing a buffering and protective role, taking into account both stability and equipment protection requirements.

[0042] Working Principle: During the installation and use of the portable computer cooling device, first adjust the device's shape according to usage requirements: If carrying or storing, hold the left support plate 1 and right support plate 2 with both hands and rotate them in opposite directions. At this time, the threaded shaft 34 in the hidden groove 31 inside the left support plate 1 and right support plate 2 will rotate around the central pivot sleeve 33 fixed in the hidden groove 31. Because the threaded shaft 34 engages with the threaded hole 32 of the support plate, the left support plate 1 and right support plate 2 will gradually approach and merge during rotation, significantly reducing the overall volume, making it easy to put into a backpack or storage bag. If using, rotate the left support plate 1 and right support plate 2 in the opposite direction until the two plates unfold to form a flat support surface, meeting the placement requirements of the laptop computer. Next, prepare for support and limiting: place the left support plate 1 and right support plate 2 in a 4-way configuration. The inclined support rod 53 in the receiving groove 51 at the bottom rear of the support plate 2 is pulled outward. The inclined support rod 53 rotates in the receiving groove 51 through the torsion spring shaft 52. After adjusting to a suitable tilt angle, the inclined support rod 53 contacts the desktop or tabletop and stays stably in that position. During this process, it will not be affected by the torsion spring shaft 52, thus forming a stable inclined support. At the same time, the baffle plate 62 in the groove 61 at the top front of the left support plate 1 and the right support plate 2 is rotated upward to make it stand up. The rubber anti-slip buffer pad 63 at the bottom of the baffle plate 62 will naturally face the direction of the computer placement, preparing for subsequent positioning. Then, the cooling is started and the computer is placed: the USB connection cable of the cooling fan 43 is connected to the USB interface of the laptop computer for power supply. After the cooling fan 43 is started, it immediately enters the " In the "downward suction" working state, the heat generated by the laptop during operation is conducted downwards through the bottom vents. The cooling fan 43 quickly draws the hot air away from the bottom of the computer by downward suction. During this process, the flat mesh 49 on top of the top pad 47 plays a key supporting role: it directly supports the weight of the laptop and prevents the bottom of the computer from directly contacting the dust filter 46, which could block the vents. At the same time, the mesh structure of the flat mesh 49 does not obstruct the downward flow of hot air, ensuring the suction efficiency of the cooling fan 43. The dust filter 46 on the top partition 44 (located below the flat mesh 49 and above the cooling fan 43) can intercept dust in the air and prevent dust from entering the fan with the suction airflow, thus avoiding dust accumulation on the fan blades. The dust filter 46 on the bottom partition 44 is located at the heat dissipation... The area beneath fan 43 also serves a dustproof function. This dual dustproof design significantly reduces the frequency of cleaning the cooling fan 43, extending its lifespan. If maintenance of the cooling components is required during use: simply lift the top pad 47 upwards. The second magnetic plate 48 at the bottom of the top pad 47 will separate from the magnetic plate 45 at the top of the partition 44, allowing you to remove the top pad 47. Next, separate the partition 44 from the base plate 41 (the magnetic plate 45 of the partition 44 will detach from the first magnetic plate 42 of the base plate 41). Clean the dust filter 46, or inspect and maintain the cooling fan 43 inside the base plate 41. There is no need to disassemble the left support plate 1 or right support plate 2. After maintenance, reinstall them in their original positions. After use, first disconnect the power to the cooling fan 43, remove the laptop, and press the diagonal support rod 53 inwards.Rotate the spring along the shaft 52 back into the receiving groove 51, then rotate the baffle plate 62 downwards to fit against the inner wall of the groove 61 for storage. Finally, rotate the left support plate 1 and the right support plate 2, and use the portable turning structure 3 to merge the left support plate 1 and the right support plate 2 together to complete the storage. The entire process requires no complicated tools, is smooth and convenient, and is suitable for various scenarios such as home office and outdoor work.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
