To achieve the above objective, firstly, the magnetic attraction control principle of the device is described, referring to fig. 10 to 14, the device selects a cylindrical shape for conveniently operating the first magnet 202 to rotate, and selects the second magnet 203 to be cylindrical for structural matching, but unlike the axial magnetizing direction of the general cylindrical magnet, the first magnet 202 and the second magnet 203 are radially magnetized, so that half columns of the first magnet 202 and the second magnet 203 are N poles, and the other half columns are S poles, as shown in fig. 12, after the N poles and the S poles of the first magnet 202 and the second magnet 203 are both attached with the iron core 204 and are attracted together, the magnetic field characteristics of the first magnet 202 and the second magnet 203 will be affected by the magnetic pole directions of the first magnet 202 and the second magnet 203, referring to fig. 13 and 14, wherein fig. 13, when the polarity directions of the first magnet 202 and the second magnet 203 are the same, most of the magnetic induction lines of the first magnet 202 and the second magnet 203 are emitted to the outside from the end part of the iron core 204 connected with the N pole under the constraint of the iron core 204, and then return from the iron core 204 connected with the S pole, so that a large amount of magnetic induction lines are concentrated at the end part of the iron core 204, so that strong magnetic force is generated at the end part of the iron core 204 and firmly adsorbed on the computer case 1, and after one hundred eighty degrees of the first magnet 202 is rotated, as shown in fig. 14, the magnetic induction lines emitted by the N pole are constrained by the iron core 204 and enter the adjacent S pole by a shortcut, which causes the magnetic force at the end part of the iron core 204 to be very weak, so that the device does not generate magnetic attraction on the computer case 1 any more, and the radiator fan 2 is easily removed from the computer case 1.

According to the magnetic attraction control principle, the gear 205 of the device is made of a magnetic conductive material, so that the magnetic field at the top end of the iron core 204 on the first magnet 202 can be pressed in the state shown in fig. 13, and the magnetic field at the bottom of the iron core 204 on the second magnet 203 can be further enhanced.

Referring to fig. 6-11, an external computer heat dissipation enhancing device includes an outer frame 201 with a chute 208 along an arc path, wherein the arc path of the chute 208 is coaxial with a heat dissipation fan 2, an end of the outer frame 201, which is located near a pressing handle 206, is provided with an assembly groove one 209, an inner wall of one side of the assembly groove one 209 is smoothly connected with a side wall of the chute 208, an opening of one end of the assembly groove one 209, which is near the pressing handle 206, is smaller than an opening of one end of the assembly groove one 209, which is connected with the chute 208, a rolling pin 210 is extruded between a hole belt 207 and the assembly groove one 209, a cushion block 211 is attached to one side of the rolling pin 210, which is near the chute 208, a pair of springs 212 are arranged in parallel with each other, a gasket 213 is arranged on one side of the rolling pin 210, which is far from the hole belt 207, the gasket 213 is attached to an inner wall of the assembly groove one 209, a flange 214 is arranged on an edge of the opening, a flange 214 is arranged on one side of the gasket 213, a top end of the rolling pin 210 is rotatably sleeved with a shaft sleeve 215, a motor of the heat dissipation fan 2 is fixedly connected with a bracket 216, and the bracket 216 is fixedly sleeved with the outer wall of the bracket 216.

According to the device, a hole belt 207 made of nonmagnetic stainless steel is inserted into a sliding groove 208 by pressing a handle 206, the gear 205 is driven to rotate through the hole belt 207, and the length and the insertion depth of the hole belt 207 are designed to drive the gear 205 to rotate by one hundred eighty degrees so as to conveniently switch the polarity direction of a magnet I202, and the magnetic force is outwards opened or closed.

To achieve the above-mentioned function, it is necessary to avoid the resilience of the hole belt 207 due to its elasticity after the hole belt 207 is inserted into the chute 208, so that the device forms a simple non-return structure by the assembly groove, the needle roller 210 and the spring 212, and the needle roller 210 is pushed toward the narrow opening of the assembly groove by the spring 212, so that good extrusion contact is maintained between the outer frame 201, the needle roller 210 and the hole belt 207, when the hole belt 207 is inserted into the assembly groove, the friction force pushes the needle roller 210 toward the wider end of the assembly groove, so that the hole belt 207 can be smoothly inserted, and when the hole belt 207 is to rebound outwards, the friction force between the hole belt 207 and the needle roller 210 can push the needle roller 210 toward the narrower direction, and a strong extrusion component force is generated on the inner wall of the assembly groove 209 and the hole belt 207, so as to lock the hole belt 207, thereby playing a non-return role.

Therefore, the device only needs to attach the heat dissipation fan 2 without external magnetic force to the surface of the computer box 1, and then simply operates to press the handle 206 to make the heat dissipation fan 2 magnetically attracted to the surface of the computer box 1, so that the operation is simple and convenient, when the device is removed, only the support 216 is required to deflect to a small extent in the direction of the compression spring 212 to drive the needle roller 210 to move to release the unidirectional locking state, the hole belt 207 can spring out through self elasticity, and the magnet 202 is driven to reverse one hundred eighty degrees to close the external magnetic force of the heat dissipation fan 2, so that the heat dissipation fan 2 can be easily removed.
