[0003] Due to space limitations, existing tablet computers can only use heat dissipation copper sheets for passive heat dissipation. The heat dissipation capacity is limited by the area of ​​the copper sheet, and the heat dissipation effect is usually poor. Utility Model Content

[0004] In order to achieve efficient heat dissipation for a tablet computer, the present application provides a heat dissipation module for a tablet computer.

[0005] The heat dissipation module for a tablet computer provided in the present application adopts the following technical solution:

[0006] A heat dissipation module for a tablet computer comprises a heat conductive sheet closely attached to a heat generating component of the tablet computer, a heat conductive tube connected to the heat conductive sheet, a heat dissipation fin connected to an end of the heat conductive tube away from the heat conductive sheet, and an air blowing member connected to the heat dissipation fin. The heat conductive sheet absorbs and dissipates heat generated by the heat generating component and transfers the heat to the heat conductive tube. The heat conductive tube quickly transfers the heat from the heat conductive sheet to the heat dissipation fin. The air outlet of the air blowing member is aligned with the heat dissipation fin to accelerate the heat dissipation on the heat dissipation fin.

[0007] By adopting the above technical solution, the heat sheet absorbs and dissipates the heat generated by the heat-generating components, and transfers the heat to the heat pipe. Since the end of the heat pipe away from the heat sheet is connected to the heat sink fin, the heat is quickly transferred from the heat sheet to the heat sink fin through the efficient thermal conductivity of the heat sink fin. The air outlet of the air blower is aimed at the heat sink fin, and the heat dissipation on the heat sink fin is further accelerated by active blowing, thereby achieving efficient heat dissipation of the tablet computer.

[0008] Preferably, a mounting groove is provided on one side of the heat conducting sheet that is in close contact with the heat generating component of the tablet computer, and a locking bracket for mounting the heat conducting sheet in the tablet computer is fixedly connected in the mounting groove.

[0009] By adopting the above technical solution, the locking bracket is used to install the heat conducting sheet on the bottom shell of the tablet computer.

[0010] Preferably, both ends of the locking bracket are fixedly connected with locking ears, and the locking ears are provided with locking holes.

[0012] Preferably, a first groove is formed on one side of the heat conducting sheet close to the heating component of the tablet computer, a second groove is formed on the heat dissipating fin, one end of the heat conducting pipe is fixed in the first groove, and the other end of the heat conducting pipe is fixed in the second groove.

[0013] By adopting the above technical solution, the setting of the first groove enables the heat pipe to be in close contact with the heat conducting sheet, and the setting of the second groove enables the heat pipe to be in close contact with the heat dissipation fin, thereby improving the efficiency of heat conduction.

[0014] Preferably, one end of the heat pipe away from the heat conducting plate extends outside the heat dissipation fins.

[0015] By adopting the above technical solution, the entire heat dissipation fin can conduct the heat of the heat pipe, so as to improve the heat dissipation efficiency of the heat dissipation fin.

[0016] Preferably, a mounting ear is fixedly connected to the housing of the blowing member, and a mounting hole is formed on the mounting ear.

[0017] By adopting the above technical solution, the arrangement of the mounting ears and the mounting holes is used to mount the air blowing member on the bottom shell of the tablet computer.

[0018] Preferably, one side of the heat dissipation fin is plugged into the air outlet of the blower, and an elastic block is fixedly connected to the top surface of the casing of the blower and located at the air outlet of the blower, and the clamping portion of the elastic block extends into the casing of the blower through a through opening, and a slot is provided on the heat dissipation fin to be clamped with the elastic block.

[0019] By adopting the above technical solution, when one side of the heat sink fin is inserted into the housing of the air blower along the air outlet of the air blower, the clamping portion of the elastic clamping block is clamped with the clamping groove, thereby fixing the heat sink fin.

[0020] Preferably, a chamfer is provided on the clamping portion of the elastic clamping block.

[0021] By adopting the above technical solution and the chamfered setting, when the clamping portion of the elastic clamping block contacts the heat sink fin, the elastic clamping block can produce elastic deformation, which is beneficial to the clamping of the clamping portion of the elastic clamping block with the clamping slot.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The heat sheet absorbs and dissipates the heat generated by the heat-generating components, and transfers the heat to the heat pipe. Since the end of the heat pipe away from the heat sheet is connected to the heat sink fin, the heat is quickly transferred from the heat sheet to the heat sink fin through the efficient heat conduction performance of the heat sink fin. The air outlet of the air blower is aimed at the heat sink fin, and the heat dissipation on the heat sink fin is further accelerated by active blowing, thereby achieving efficient heat dissipation of the tablet computer;

[0024] 2. The setting of the first groove enables the heat pipe to be in close contact with the heat conducting sheet, and the setting of the second groove enables the heat pipe to be in close contact with the heat dissipation fin, thereby improving the efficiency of heat conduction;

[0025] 3. When one side of the heat sink fin is inserted into the housing of the air blower along the air outlet of the air blower, the clamping portion of the elastic clamping block is clamped with the clamping groove, thereby fixing the heat sink fin. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a heat dissipation module for a tablet computer. Figure 1 and Figure 2The heat dissipation module for a tablet computer includes a heat conductive sheet 1 which is closely attached to heat generating components such as a CPU and a GPU of the tablet computer, a heat conductive pipe 2 connected to the heat conductive sheet 1, a heat dissipation fin 3 connected to an end of the heat conductive pipe 2 which is away from the heat conductive sheet 1, and an air blowing member 4 connected to the heat dissipation fin 3; the heat conductive sheet 1 absorbs and dissipates the heat generated by the heat generating components, and transfers the heat to the heat conductive pipe 2; since the end of the heat conductive pipe 2 which is away from the heat conductive sheet 1 is connected to the heat dissipation fin 3, the heat is quickly transferred from the heat conductive sheet 1 to the heat dissipation fin 3 through the efficient heat conductive performance of the heat dissipation fin 3; the air outlet of the air blowing member 4 is aligned with the heat dissipation fin 3, and the heat dissipation on the heat dissipation fin 3 is further accelerated by actively blowing air, thereby completing the heat dissipation of the heat generating components of the tablet computer.

[0033] Reference Figure 1 and Figure 2 The heat conducting sheet 1 is provided with two symmetrically arranged mounting grooves 11 on one side which is in close contact with the heating component of the tablet computer. The notches of the mounting grooves 11 face the heating component of the tablet computer. A locking bracket 12 for mounting the heat conducting sheet 1 in the tablet computer is fixedly connected in each mounting groove 11, and the locking bracket 12 does not protrude outside the notch of the mounting groove 11, so that the side of the heat conducting sheet 1 provided with the mounting groove 11 can be in close contact with the heating component of the tablet computer. Locking ears 121 with locking holes 122 are integrally formed at both ends of each locking bracket 12. A yielding opening 13 corresponding to the position of the locking ear 121 is provided on the heat conducting sheet 1. The setting of the yielding opening 13 plays the role of yielding the locking ear 121. The setting of the locking ear 121 is used to mount the heat conducting sheet 1 in the bottom shell of the tablet computer.

[0034] Reference Figure 1 and Figure 2 The heat conducting sheet 1 is closely attached to one side of the heating component of the tablet computer and a first groove 14 is provided between the two mounting grooves 11, the groove opening of the first groove 14 faces the heating component of the tablet computer, the heat conducting tube 2 is in the shape of a bent flat strip as a whole, one end of the heat conducting tube 2 is fixed in the first groove 14, and the heat conducting tube 2 does not protrude outside the groove opening of the first groove 14, so that the side of the heat conducting sheet 1 with the first groove 14 can be closely attached to the heating component of the tablet computer.

[0035] In this embodiment, the heat conducting sheet 1 is a copper sheet, and the heat conducting tube 2 is a copper tube. Copper has a relatively high thermal conductivity and can quickly conduct heat from the heat source to other areas. Copper can still maintain its thermal conductivity at higher temperatures, which makes copper very suitable for applications that need to work in a higher temperature environment. On the other hand, compared with other metals, copper has a lower thermal expansion coefficient, which helps to reduce structural deformation caused by temperature changes. Copper can conduct heat evenly, which helps to avoid the generation of local hot spots and improve the overall heat dissipation efficiency.

[0036] Reference Figure 1 and Figure 2 The heat sink fin 3 is composed of a plurality of thin sheets, each of which has a gap between them. The shape is designed to increase the heat dissipation surface area of ​​the heat sink fin 3 and improve the heat dissipation speed. The heat sink fin 3 is provided with a second groove 31. The end of the heat pipe 2 away from the heat conductive sheet 1 is fixedly connected in the second groove 31, and the heat pipe 2 does not protrude outside the notch of the second groove 31. The end of the heat pipe 2 away from the heat conductive sheet 1 extends to the outside of the heat sink fin 3. This design enables the entire heat sink fin 3 to conduct the heat of the heat pipe 2 to improve the heat dissipation efficiency of the heat sink fin 3.

[0037] Reference Figure 2 and Figure 3 In this embodiment, the blowing member 4 is a turbo blower, and a mounting ear 41 with a mounting hole 42 is fixedly connected to the casing of the turbo blower, so that the turbo blower can be installed in the bottom shell of the tablet computer through the mounting hole 42; the turbo blower is connected to the power supply of the tablet computer through the circuit, so that the turbo blower is powered by the tablet computer. The air inlet of the turbo blower is arranged vertically, and the air outlet of the turbo blower is arranged laterally, and the air outlet of the turbo blower faces the heat sink 3 and is connected to the heat sink 3; thereby further accelerating the heat dissipation on the heat sink 3 by actively blowing air. It should be noted that the bottom shell of the tablet computer is a hollow shell with an opening at the top, and a heat dissipation hole corresponding to the position of the heat sink fin 3 is opened on the side of the bottom shell of the tablet computer, and the heat dissipation hole is located on the side of the heat sink fin 3 away from the turbo blower, so that the hot air blown out from the heat sink fin 3 can be discharged from the heat dissipation hole to the outside of the tablet computer; at the same time, an air inlet is also opened on the bottom shell of the tablet computer to form an air flow in the tablet computer.

[0038] Turbo blowers are smaller in size and can provide efficient airflow in limited spaces, making them suitable for use in tablets. Due to the blade and motor design of turbo blowers, they are usually quieter in operation than axial fans of equivalent performance.

[0039] Reference Figure 3 and Figure 4One side of the heat dissipation fin 3 is plugged into the air outlet of the turbo blower, and a bent elastic block 43 is fixedly connected to the top surface of the casing of the turbo blower and located at the air outlet of the turbo blower. A through hole 44 corresponding to the position of the elastic block 43 is provided on the top surface of the casing of the turbo blower, and the clamping portion of the elastic block 43 extends into the casing of the turbo blower through the through hole 44, and a chamfer is provided on the clamping portion of the elastic block 43 so that when the clamping portion of the elastic block 43 contacts the heat dissipation fin 3, the bent elastic block 43 can produce elastic deformation; a clamping groove 32 corresponding to the position of the elastic block 43 is provided on the heat dissipation fin 3, and when one side of the heat dissipation fin 3 is plugged into the casing of the turbo blower along the air outlet of the turbo blower, the clamping portion of the elastic block 43 is clamped with the clamping groove 32, thereby fixing the heat dissipation fin 3. At the same time, in order to make the heat dissipation fins 3 more firmly fixed to the casing of the turbo blower, welding can be performed at the connection between the heat dissipation fins 3 and the casing of the turbo blower after the clamping portion of the elastic clamping block 43 is clamped and fixed to the clamping groove 32.

[0040] The implementation principle of a heat dissipation module for a tablet computer in an embodiment of the present application is as follows: when current flows, heat-generating components such as the CPU and GPU in the tablet computer will generate heat, which is first initially absorbed by the heat conductive sheet 1 through passive heat dissipation; then, the heat is rapidly transferred to the heat dissipation fins 3 through the efficient heat conduction of the heat conductive pipe 2. At this time, the turbo blower starts to work, generating a strong airflow to blow through the heat dissipation fins 3, and rapidly taking away the heat on the heat dissipation fins 3, thereby achieving efficient heat dissipation of the tablet computer.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
