A mounting hole is provided on the surface of the cross plate 3, which is used for installing the cooling fan 6. After installation, the width of the folded edge 4 of the cross plate 3 is not higher than the fixing plate 2, so as to avoid the situation where the fixing plate 2 is suspended due to the protrusion of the folded edge 4, making it impossible for the fixing plate 2 to be installed through the mounting hole at the end. The length of the cross plate 3 is equal to the distance between the two fixing plates 2.

[0024] Preferably: one side of the folding edge 4 is connected to a mounting seat 7, a guide rod 8 is arranged on the inner side of the mounting seat 7, a movable block 9 is sleeved on the outer wall of the guide rod 8, a spring 10 is sleeved on the outer wall of the guide rod 8, a latch 11 is connected to one end of the movable block 9, a shift block 12 is connected to the outer wall of the movable block 9, and a slot 13 is provided on the outer wall of the fixed plate 2;

[0025] It should be noted that the heat dissipation fan 6 is connected to an external power supply and a control switch, and the mounting base 7, the guide rod 8, the movable block 9, the spring 10, the latch 11, the shift block 12, and the slot 13 can be combined into a heat dissipation component, and the heat dissipation component has two sets of symmetrically distributed horizontal plates 3 that can fit together with the tablet computer motherboard 1.

[0026] The sizes of the latch 11 and the slot 13 are matched, an opening is provided on the outer wall of the mounting seat 7, and one end of the shift block 12 extends to the outside through the opening on the outer wall of the mounting seat 7.

[0029] It should be noted that the cooling fan 6 can be installed on the horizontal plate 3 by screws, and the installation position of the cooling fan 6 will cover the surface of the through hole 5, so that when the cooling fan 6 is started, the heat generated by the split tablet computer motherboard 1 is dissipated through the through hole 5.

[0030] Working principle: When using the split tablet computer motherboard, first, by installing the heat dissipation fan 6 on the horizontal plate 3, and the installation position of the heat dissipation fan 6 will cover the surface of the through hole 5, so that when the heat dissipation fan 6 is started, the heat generated by the split tablet computer motherboard 1 is dissipated through the through hole 5, and then the movable block 9 drives the bayonet 11 to contract by shifting the shift block 12, and then the horizontal plate 3 is set between the two fixed plates 2, and after it is fitted with the tablet computer motherboard 1, by releasing the shift block 12, the bayonet 11 will be reset under the action of the movable block 9 and the spring 10 and inserted into the outer wall of the fixed plate 2. The card slot 13 of the heat dissipation fan 6 can be installed and fixed, so that the installation can be carried out without the screws passing through the tablet computer motherboard 1, thereby avoiding squeezing and damage to the tablet computer motherboard 1. When disassembling, the movable block 9 drives the card pin 11 to disengage from the card slot 13 by toggling the toggle block 12, and then the cross plate 3 and the heat dissipation fan 6 can be removed by pulling outward. The heat dissipation fan 6 can be easily removed in the above manner for maintenance by the staff. Compared with the installation method in which the screws pass through the motherboard, the heat dissipation fan 6 installed in the manner in which the screws pass through the motherboard can avoid damage and cracking of the motherboard caused by repeated twisting of the screws.
