[0026] The number of the placing boards 1 is two. The ventilation cavity 2 is opened inside the placing board 1 and penetrates through one end of the placing board 1 to form the air inlet 4. The setting of the air inlet 4 can allow air to enter the ventilation cavity 2. The cooling fan 5 is fixedly installed at the air inlet 4 and can send external air into the inside of the ventilation cavity 2. The air outlets 3 are provided on the opposite sides of the two ventilation cavities 2 and can blow out air to cool the computer.

[0027] Among them, the width adjusting assembly includes a connecting rod one 6 and a connecting rod two 7 that are rotatably connected. A tightening knob 8 is provided at the connection of the connecting rod one 6 and the connecting rod two 7. One ends of the connecting rod one 6 and the connecting rod two 7 are respectively installed with slide blocks 9. Sliding grooves 10 are respectively opened at the bottoms of the two placing boards 1. The slide blocks 9 are slidably connected with the sliding grooves 10. The other ends of the connecting rod one 6 and the connecting rod two 7 are respectively hinged to the two placing boards 1.

[0028] The tensioning knob 8 is rotatably connected to the middle of the first connecting rod 6 and the second connecting rod 7. Rotating the tensioning knob to loosen it enables the first connecting rod 6 and the second connecting rod 7 to rotate relative to each other. Tightening the tensioning knob 8 can fix the first connecting rod 6 and the second connecting rod 7, and can fix the width between the two placing plates 1. The two sliders 9 are respectively bolted to one ends of the first connecting rod 6 and the second connecting rod 7. The sliding groove 10 is opened at the middle position of the bottom of the placing plate 1 and extends to one end of the placing plate 1. The sliding groove 10 can guide the movement of the slider 9. The other ends of the first connecting rod 6 and the second connecting rod 7 are respectively hinged to the other ends of the bottoms of the two placing plates 1. With such a setting, when adjusting the width, the placing plate 1 can abut against one end of the first connecting rod 6 and the second connecting rod 7, causing the sliders 9 at the ends of the first connecting rod 6 and the second connecting rod 7 to move towards the other end of the sliding groove 10. When adjusting the width, the two placing plates 1 can always be kept relatively parallel.

[0029] On the basis of the above embodiment, specifically, limit blocks 11 are respectively provided at one ends of the two sliding grooves 10. The limit blocks 11 are inserted into one ends of the sliding grooves 10. When adjusting the width, it can prevent the slider 9 from detaching from the sliding groove 10, which is convenient for the storage of the heat dissipation rack.

[0030] Furthermore, the pitch angle adjustment assembly includes support legs 12 respectively installed on the two placing plates 1. A plurality of adjustment grooves 13 are opened on the support legs 12. Locking rods 14 are provided on the placing plates 1. One ends of the two locking rods 14 are respectively inserted into the adjustment grooves 13. The support legs 12 are hinged to the side walls of the two placing plates 1. The adjustment grooves 13 are opened at the tops of the support legs 12. The two locking rods 14 are respectively hinged to the side walls of the two placing plates 1. By inserting the locking rods 14 into the adjustment grooves 13, the support legs 12 can be supported to fix the pitch angle of the placing plates 1, which is convenient for placing the computer at an appropriate position.

[0031] In one embodiment, specifically, anti-slip pads 15 are respectively provided on the two placing plates 1. The anti-slip pads 15 are provided with a hollowed-out design, and a plurality of heat dissipation holes 16 are formed at the hollowed-out parts. The two anti-slip pads 15 are respectively adhered to the tops of the two placing plates 1, which can increase the friction between the contact surface of the computer and the placing plate 1 and prevent the computer from sliding on the placing plate 1. The hollowed-out design forms a plurality of heat dissipation holes 16, enabling the heat generated by the computer to be discharged more quickly. The anti-slip pads 15 are made of flexible materials and can play a role of buffering and shock absorption when placing the computer.

[0032] Specifically, anti-slip-off plates 17 are respectively installed on the two placing plates 1. The anti-slip-off plates 17 are bolted to one ends of the two placing plates 1, which can hold the computer to prevent it from slipping.

[0033] Even further, anti-slip rubber pads 18 are respectively provided at the bottoms of the two support legs 12. The anti-slip rubber pads 18 are adhered to the bottoms of the support legs 12, which can prevent the support legs 12 from sliding and increase the stability of the placement of the heat dissipation rack.

[0034] When in use, first turn the tightening knob 8 to loosen it, and then pull the two placement plates 1 outward. Since one ends of the first connecting rod 6 and the second connecting rod 7 are hinged to the placement plate 1, the other ends of the first connecting rod 6 and the second connecting rod 7 move towards the other end of the placement plate 1, and the first connecting rod 6 and the second connecting rod 7 start to rotate relative to each other, so that the two placement plates 1 always remain relatively parallel. When the two placement plates 1 reach the required width, tighten the tightening knob 8. At this time, the width between the two placement plates 1 is fixed. Insert the locking rod 14 into the corresponding adjustment groove 13 of the support leg 12 to adjust the pitch angle of the placement plate 1. After the heat dissipation rack is set up, place the computer on the placement table. The anti-slip pad 15 and the anti-disengagement plate 17 can fix the computer. When heat dissipation of the computer is required, turn on the heat dissipation fan 5. Under the action of the heat dissipation fan 5, external air enters the ventilation cavity 2 from the air inlet 4, and the air in the ventilation cavity 2 is blown from the air outlet 3 to the bottom of the computer, which can dissipate the heat of the computer. At the same time, the heat dissipation holes 16 of the anti-slip pad 15 can assist the heat dissipation fan 5 to discharge the heat accumulated at the bottom of the computer, improving the heat dissipation efficiency. After use, take the computer away from the placement table. When the heat dissipation rack needs to be stored, turn the tightening knob 8 to loosen it, and then push the two placement plates 1 inward, and remove the locking rod 14 from the adjustment groove 13. When one ends of the first connecting rod 6 and the second connecting rod 7 touch the bottom of the support leg 12, the support leg 12 can be supported. When the slider 9 moves to the limit block 11, the width between the two placement plates 1 reaches the minimum. At this time, tighten the tightening knob 8 to complete the storage of the heat dissipation rack.
