The present invention is described in detail below in conjunction with the drawings.

[0024] This embodiment provides a heat dissipation structure of a computer terminal, such as Figures 1 to 7 , including a fan 1, a heat sink 2, a mounting seat 3 and a plurality of locking members 4, the heat sink 2 is provided with a cavity 5, the fan 1 can be detachably mounted in the cavity 5, the mounting seat 3 is provided with a positioning base 6, the bottom of the heat sink 2 is provided with a positioning cavity 20, the positioning cavity 20 is used for detachably mounting the positioning base 6, and the shape of the positioning cavity 20 is adapted to the shape of the positioning base 6, the positioning base 6 is provided with a magnetic suction block (not shown in the attached drawings), the heat sink 2 is a metal part; the mounting seat 3 is provided with a plurality of mounting feet 8, the mounting feet 8 are provided with mounting holes 9, the locking member 4 is provided with a fixing portion 10 and a fixing foot 11, the fixing portion 10 is mounted in the mounting hole 9, the fixing foot 11 is used for detachably mounting on the mainboard 19, the periphery of the heat sink 2 is provided with a plurality of groups of heat dissipation fins, and the plurality of groups of heat dissipation fins are arranged at equal intervals. Among them, the fan 1 of this embodiment adopts a magnetic suspension bearing fan 1, and the noise of the fan 1 when working will be smaller.

[0025] Specifically, Figures 2 to 5 As shown, the fan 1 is installed in the cavity 5 of the radiator 2, and the fan 1 can be fixed by a fixing method in the prior art, such as screws, etc., which is not limited in this embodiment. The radiator 2 of this embodiment is a metal device, such as made of aluminum. The bottom of the radiator 2 is provided with a positioning cavity 20 that is compatible with the positioning base 6, that is, during assembly, the positioning base 6 and the positioning cavity 20 can achieve the positioning function. The bottom of the radiator 2 is provided with a screw hole, and the mounting seat 3 is provided with a through hole corresponding to the screw hole. Therefore, after the positioning cavity 20 and the positioning base 6 are positioned, and the mounting seat 3 is adsorbed on the radiator 2 by the magnetic block, the through hole and the screw hole can be aligned, and then the mounting seat 3 is locked with the radiator 2 by penetrating the through hole with a screw and screwing it into the screw hole. This embodiment realizes the positioning of the assembly by providing a magnetic block, a positioning cavity 20 and a positioning base 6, which is convenient for improving the efficiency of actual production assembly.

[0026] Furthermore, the mounting feet 8 of this embodiment are provided with a plurality of Figure 5 The four mounting feet 8 shown in the figure each have a square mounting hole 9, the locking member 4 is provided with a slot, and the fixing portion 10 is located in the slot, so that during assembly, the hole wall of the mounting hole 9 is embedded in the slot and fits with the side wall of the fixing portion 10, thereby fixing the locking member 4 and the mounting foot 8 for assembly, and the locking member 4 cannot rotate, and the assembly stability is higher.

[0027] Furthermore, the fixing foot 11 of the locking member 4 is as follows Figure 7 As shown, it includes a first fixing rod 14 and a second fixing rod 15, a gap 17 is set between the first fixing rod 14 and the second fixing rod 15, and a block 16 is protruded from one end of the first fixing rod 14 and the second fixing rod 15 away from the gap 17. The main board 19 is provided with a through hole (not shown in the drawings), and the block 16 is used to be connected to the through hole.

[0028] Specifically, during assembly, since a gap 17 is provided between the first fixing rod 14 and the second fixing rod 15, when inserted into the through hole of the main board 19, the first fixing rod 14 and the second fixing rod 15 are squeezed by the through hole, so that after the clamping block 16 passes through the through hole, it is clamped at the bottom of the through hole, connecting the main board 19 to the mounting seat 3, thereby assembling the radiator 2 and the fan 1 on the main board 19. Without the assistance of external force, the radiator 2 is not easy to loosen and the installation is stable.

[0029] like Figure 5 In this embodiment, a bending portion 13 is provided between the mounting foot 8 and the mounting seat 3. After the mounting foot 8 is installed to the mainboard 19 through the locking member 4, a heat dissipation space 7 is formed between the mounting seat 3 and the mainboard 19. Therefore, the radiator 2 of this embodiment can be installed above the load and the device with large heat generation of the mainboard 19, such as the main chip, so that the main chip is in the heat dissipation space 7, and the heat generated by the main chip is guided and dissipated by the radiator 2, and the air convection is improved by the fan 1 to increase the heat dissipation effect.

[0030] like Figure 4 As shown, the heat sink fins of this embodiment include two heat sinks 12, which are arranged in an eight-shaped pattern, that is, the heat sink 12 is inclined relative to the radiator 2. The eight-shaped heat sink 12 helps to increase the surface area of ​​the heat sink 12 and improve the heat dissipation effect. Figure 4 The arrangement of the heat sink 12 shown can increase the area of ​​the heat sink 12 while ensuring the number of the heat sink 12 , so that the radiator 2 can achieve the maximum heat dissipation effect.

[0031] In addition, this embodiment is also provided with a temperature detection module (not shown in the drawings), and the temperature detection module and the fan 1 are both connected to the control module signal of the mainboard 19. The temperature detection module is used to detect the temperature of the radiator 2, and the control module of the mainboard 19 adjusts the speed of the fan 1 according to the detection signal of the temperature detection module.

[0032] Specifically, when the temperature inside the chassis rises or the temperature of the radiator 2 rises, it means that the current heat dissipation efficiency is low. The control module of the mainboard controls the speed of fan 1 to increase according to the detection signal of the temperature detection module to improve the heat dissipation efficiency. When the temperature drops, the fan 1 is controlled to reduce the speed to avoid wasting resources. In actual settings, multiple temperature gears can be set. When the corresponding gear is reached, the fan 1 is changed to the corresponding speed to achieve a more flexible heat dissipation effect.

[0033] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model.
