Description

Technical Field

[0001] This utility model relates to the field of flat plate heat dissipation technology, specifically a liquid-cooled flat plate heat dissipation structure. Background Technology

[0002] A tablet computer is a small, portable personal computer that uses a touchscreen as its basic input device. Users can input data through a stylus, digital pen, handwriting recognition, on-screen soft keyboard, voice recognition, or an external keyboard.

[0003] Current tablet PC cooling methods are generally passive. To improve heat dissipation, active cooling has emerged, typically using external heat sinks. These external heat sinks usually consist of a heat sink plate and a fan. The heat sink plate makes close contact with the tablet, absorbing and dissipating the heat generated by the tablet, while the fan blows away heat from the surface of the heat sink plate, thus accelerating the cooling process. However, in practical applications, this cooling method has significant drawbacks. Because different components inside a tablet generate heat at varying rates, heat dissipation is uneven across different parts of the tablet. This means that different parts of the heat sink absorb heat differently. Based on the principle of heat transfer, heat moves from high-temperature areas to low-temperature areas. Uneven heat distribution on the heat sink plate complicates the direction and speed of heat transfer, making it difficult to dissipate heat quickly and effectively, ultimately resulting in low overall cooling efficiency. This not only affects the tablet's performance under heavy workloads but may also shorten the device's lifespan due to localized overheating.

[0004] In view of this, we propose a liquid-cooled flat plate heat dissipation structure. Utility Model Content

[0005] The purpose of this utility model is to provide a liquid-cooled flat plate heat dissipation structure, which solves the problem of uneven heat dissipation in external heat sinks for flat plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A liquid-cooled tablet heat dissipation structure includes a tablet computer with a charging port for charging and discharging the tablet computer, a liquid cooling mechanism for liquid cooling the tablet computer, and a power supply mechanism for connecting to the charging port to supply power to the liquid cooling mechanism.

[0010] Preferably, the annular heat sink is provided with an annular array of through holes for air circulation and heat dissipation.

[0011] Preferably, the outer wall of the connecting shaft is rotatably connected to the inner wall of the liquid cooling plate, and the stirring rod is symmetrical about the connecting shaft as the midpoint.

[0012] Preferably, the power extraction mechanism includes a connecting end, the outer wall of which is provided with a gooseneck tube, one end of which is fixedly connected to the connecting end, and the other end of which is fixedly connected to a plug.

[0014] By employing the above technical solution, this utility model provides a liquid-cooled flat plate heat dissipation structure. It possesses at least the following beneficial effects:

[0015] 1. This utility model incorporates a liquid cooling mechanism. A bidirectional motor drives the connecting shaft and stirring rod to rotate. The stirring rod stirs the coolant inside the liquid cooling plate, which enhances the fluidity of the coolant and creates a more uniform temperature distribution inside the liquid cooling plate, preventing localized overheating. In addition, stirring accelerates the heat exchange between the coolant and the inner wall of the liquid cooling plate, improving heat transfer efficiency and thus removing heat from the tablet computer more quickly, thereby improving the overall heat dissipation performance.

[0016] 2. This utility model incorporates a liquid cooling mechanism. During airflow, the annular heat sink dissipates heat. The heat from the computer tablet enters the annular heat sink through the magnetic plate and liquid cooling plate. The liquid cooling plate plays a role in conduction and heat absorption, allowing the heat inside the tablet to be quickly transferred to the coolant. The heat from the annular heat sink is then carried away by the airflow, achieving liquid cooling.

[0017] 3. This utility model incorporates a power-gathering mechanism; after the connector is inserted into the charging port, it provides power to the liquid cooling mechanism. By adjusting the bending angle of the gooseneck tube, the installation position of the liquid cooling mechanism can be changed and kept stable. When the tablet computer does not require heat dissipation, the liquid cooling mechanism can be oriented to direct airflow towards the user, achieving a cooling effect. Attached Figure Description

[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 - Figure 7As shown, this utility model provides a technical solution: a liquid-cooled flat-panel heat dissipation structure, including a tablet computer 1, on which a liquid cooling mechanism 3 is provided. The liquid cooling mechanism 3 includes: a liquid cooling plate 31, the inner wall of which is hollow, and a coolant is placed on the inner wall of the liquid cooling plate 31 for heat conduction and absorption. The coolant inside the liquid cooling plate 31 can be made of a material with high thermal conductivity, such as water coolant or nano coolant, to improve heat dissipation efficiency and prevent equipment performance degradation or damage due to high temperature. A magnetic suction plate 32 is fixedly connected to the outer wall of the liquid cooling plate 31, and a magnetic suction frame 33 is provided on the outer wall of the liquid cooling plate 31. A side filter screen 34 is provided on the side of the magnetic suction frame 33 for air intake, and an upper filter screen 35 is provided on the side of the magnetic suction frame 33 away from the liquid cooling plate 31 for exhaust. A ring is provided on the side of the liquid cooling plate 31 near the magnetic suction plate 32. The ring-shaped magnetic suction component 36 is used to attract and fix the magnetic frame 33. This design also facilitates the removal and cleaning of the side filter screen 34 and the upper filter screen 35. The ring-shaped heat sink 37 is fixedly connected to the outer wall of the liquid cooling plate 31. The ring-shaped heat sink 37 can be made of high thermal conductivity materials, such as aluminum alloy or copper alloy, and its surface is anodized or plated to enhance corrosion resistance, improve heat dissipation effect and service life. A bidirectional motor 38 is provided on the liquid cooling plate 31. One end of the output shaft of the bidirectional motor 38 is fixedly connected to the fan blade 39, and the other end of the output shaft of the bidirectional motor 38 is fixedly connected to the connecting shaft 310. A stirring rod 311 is fixedly connected to the inner wall of the connecting shaft 310. A power supply mechanism 4 is provided on the liquid cooling plate 31 to supply power to the liquid cooling mechanism 3.

[0029] The tablet computer 1 is equipped with a charging port 2 for charging and discharging. The charging port 2 adopts a bidirectional fast charging protocol, which enables the tablet computer 1 to not only charge quickly, but also to act as a power source to power other devices under certain circumstances, thereby improving energy efficiency. The back of the tablet computer 1 is provided with a slot, which is made of magnetic material to facilitate the magnetic attraction of the magnetic plate 32. The annular heat sink 37 is provided with an annular array of through holes for air circulation and heat dissipation. The outer wall of the connecting shaft 310 is rotatably connected to the inner wall of the liquid cooling plate 31. The stirring rod 311 is symmetrical about the connecting shaft 310 as the midpoint, ensuring that the stirring rod 311 is subjected to balanced force when rotating, avoiding vibration or additional resistance caused by eccentricity, and ensuring stable operation.

[0030] The power-gathering mechanism 4 includes a connecting end 41, with a gooseneck tube 42 on the outer wall of the connecting end 41. One end of the gooseneck tube 42 is fixedly connected to the connecting end 41, and the other end of the gooseneck tube 42 is fixedly connected to a connector 43. The gooseneck tube 42 can be made of a highly flexible material, such as a silicone-coated metal flexible tube, to ensure that it can be bent and adjusted at an angle while providing sufficient support to allow the connector 43 to stably connect to the charging port 2. The connector 43 is designed as a multi-functional interface, compatible with different types of devices, such as Type-C, Lightning, or USB-A, giving the power-gathering mechanism 4 a wider range of applicability and meeting the power supply needs of various devices. The connector 43 is used to plug into the charging port 2. The gooseneck tube 42 has conductive wires inside, and the gooseneck tube 42 has the characteristics of being flexible and easy to adjust its shape. Its internal conductive wires can ensure power supply while allowing the connector 43 to flexibly plug into the charging port 2 of the tablet computer 1, and facilitate the adjustment of the position and angle of the power-gathering mechanism 4.

[0031] When the liquid-cooled flat plate heat dissipation structure of this utility model is in use, the bidirectional motor 38 is turned on, the bidirectional motor 38 drives the fan blade 39, the fan blade 39 drives the air to enter through the side filter screen 34 and exit through the upper filter screen 35. The side filter screen 34 and the upper filter screen 35 play the role of filtering the air and preventing outside air from entering the bidirectional motor 38 and causing damage.

[0032] Meanwhile, the airflow dissipates heat from the annular heat sink 37. The heat from the tablet computer 1 enters the annular heat sink 37 through the magnetic suction plate 32 and the liquid cooling plate 31. The liquid cooling plate 31 plays the role of conduction and heat absorption, so that the heat inside the tablet computer 1 can be quickly transferred to the coolant. Then, the heat from the annular heat sink 37 is carried away by the airflow for liquid cooling.

[0033] Furthermore, the bidirectional motor 38 drives the connecting shaft 310 and the stirring rod 311 to rotate. The stirring rod 311 stirs the coolant inside the liquid cooling plate 31, which enhances the fluidity of the coolant and creates a more uniform temperature distribution inside the liquid cooling plate 31, preventing localized overheating. In addition, stirring can accelerate the heat exchange between the coolant and the inner wall of the liquid cooling plate 31, improve heat transfer efficiency, and thus remove the heat from the tablet computer 1 more quickly, improving the overall heat dissipation performance.

[0034] After the connector 43 is inserted into the charging port 2, it provides power to the liquid cooling mechanism 3. By adjusting the bending angle of the gooseneck tube 42, the installation position of the liquid cooling mechanism 3 can be changed and kept stable. When the tablet computer 1 does not require heat dissipation, the liquid cooling mechanism 3 can be adjusted to direct the airflow towards the user, achieving a cooling effect.
