In a further embodiment, referring to fig. 4, 12 and 13, the heat dissipating body 300 includes a heat dissipating cover 310, an air inlet 312 and an air outlet 311 are provided on the heat dissipating cover 310, and a fan 313 and a plurality of heat dissipating fins 314 are provided inside the heat dissipating cover 310.
The bottom surface of the heat dissipation cover 310 is provided with a semiconductor cooling fin 330, and the semiconductor cooling fin 330 is in contact with the upper surface of the heat conduction mounting plate 400.
In combination with the above embodiment, the application principle and working process of the invention are as follows:
initially, the two heat conductive clamping plates 200 are in a unfolded state, and simultaneously the pulling plate 700 and the heat conductive clamping plates 200 are separated from each other, and are locked by the locking structure, and the first spring 720 is compressed to a limit state.
During the installation, the adapter body 100 is placed between the two heat conductive clamping plates 200, and then the adapter body 100 is pushed upward so that the adapter body 100 gradually approaches the heat conductive mounting plate 400. In pushing up the adapter body 100, since it is difficult for a manual operation to ensure that the adapter body 100 moves upward in a posture parallel to the top surface of the heat conductive mounting plate 400, there may be an unlocking lever 620 that causes one end of the adapter body 100 to contact the corresponding side first due to the inclined upward movement of the adapter body 100. In the following, referring to the drawings, the adaptor body 100 is first contacted with the left unlocking lever 620, and for convenience of description, the left unlocking lever 620 is named as a first lever, and the right unlocking lever 620 is named as a second lever.
In the process of pushing the adapter body 100 upwards, as the adapter body 100 continuously moves upwards, the adapter body 100 contacts the first compression bar first and then contacts the second compression bar, after the adapter body 100 contacts the first compression bar and/or the second compression bar, the first compression bar and/or the second compression bar is pushed to rotate, and when the first compression bar and/or the second compression bar rotate, the hollow shaft 622 is driven to rotate, so that the corresponding locking piece 630 moves in a direction away from the center of the wheel disc 510. Because the adapter body 100 first contacts with the first compression bar, the first compression bar reaches the unlocking angle first, and when the first compression bar reaches the unlocking angle, the locking piece 630 corresponding to the first compression bar is disengaged from the locking groove 612, and at the same time, one side of the adapter body 100 corresponding to the first compression bar is already contacted with the rubber pad at the top of the heat-conducting mounting plate 400, so that the rubber pad is compressed to a preset degree. Then, as the adapter body 100 continues to move upwards, the second pressing rod reaches the unlocking angle, the locking piece 630 corresponding to the second pressing rod is separated from the locking groove 612, meanwhile, one side of the adapter body 100 corresponding to the second pressing rod is already in contact with the rubber pad at the top of the heat conducting mounting plate 400 and enables the rubber pad to be compressed to a preset degree, and the first pressing rod continues to rotate for a certain angle along with the second pressing rod reaching the unlocking angle, so that after the second pressing rod reaches the unlocking angle, the angles of the first pressing rod and the second pressing rod are inconsistent, that is, the adapter body 100 is not parallel to the top of the heat conducting mounting plate 400, and at the moment, the right side of the wheel disc 510 stretches into the limiting groove 410 due to the fact that the wheel disc 510 is driven to deflect to the right side by the locking piece 630 after the first pressing rod reaches the unlocking angle.
After that, the adapter body 100 is pushed upwards continuously, because the extrusion force between the left side of the adapter body 100 and the first compression bar is greater than the extrusion force between the right side of the adapter body 100 and the second compression bar, so that the adapter body 100 is deflected to the left side gradually, the wheel disc 510 is also deflected to the right gradually, when the angle between the second compression bar and the first compression bar is consistent, the wheel disc 510 is separated from the limit groove 410 and deflected to the right, the wheel disc 510 rotates under the action of the first torsion spring and drives the connecting rod 520 to rotate, the connecting rod 520 drives the heat conduction clamping plate 200 to approach the adapter body 100 and clamp the adapter body 100, at this time, because the angles of the first compression bar and the second compression bar are consistent, the top surface of the adapter body 100 is basically parallel to the top surface of the heat conduction mounting plate 400, the adapter body 100 is also basically in a parallel contact state with the heat conduction rubber pad 900 on the heat conduction mounting plate 400, the parallel contact between the adapter body 100 and the heat conduction rubber pad 900 on the heat conduction mounting plate 400, so that the contact effect of the two is better, the extrusion of the heat conduction rubber pad 900 is even, and the heat dissipation effect is better. After the heat conduction clamping plate 200 clamps the adapter body 100, the locking structure is released, the first elastic piece is reset, so that the pull plate 700 approaches to the heat conduction clamping plate 200, the adapter body 100 is clamped in the up-down direction, and the matching installation between the heat dissipating device and the adapter body 100 is completed.
Naturally, if the adapter body 100 is in a horizontal state during pushing the adapter body 100 upwards, the first compression bar and the second compression bar reach the unlocking angle at the same time, which means that the adapter body 100 is in good contact with the heat-conducting rubber pad 900, after the first compression bar and the second compression bar reach the unlocking angle, the unlocking disc 610 is in a horizontal state to unlock directly, and the wheel disc 510 releases and drives the heat-conducting clamping plate 200 to approach to clamp the adapter body 100 through the connecting rod 520; when the unlocking pressure lever 620 (i.e., the first pressure lever and the second pressure lever) is set to reach the unlocking angle, the heat-conducting rubber pad 900 on the heat-conducting mounting plate 400 is compressed to a preset degree, so as to ensure that in the process of pushing the first pressure lever and the second pressure lever upwards by the adapter body 100, if the adapter body 100 can always keep the level, the first pressure lever and the second pressure lever are unlocked simultaneously, and in this case, the heat-conducting rubber pad 900 on the heat-conducting mounting plate 400 is also in a compressed state, and the heat-conducting rubber pad 900 on the adapter body 100 and the heat-conducting mounting plate 400 can still be in relatively reliable contact, so that the heat transfer effect of the adapter body 100 and the heat-conducting mounting plate 400 is ensured. It can be understood that the adapter body 100 is in a horizontal state and is not easy to control during the operation, if the adapter body 100 is not in a horizontal state, during the clamping process, due to the compression of the heat-conducting rubber pad 900 and the deformation of the first compression bar and the second compression bar, the first compression bar and the second compression bar may not be unlocked at the same time, and finally the situation that the rotation angles of the first compression bar and the second compression bar are different occurs, at this time, if the adapter body 100 is clamped, the adapter body 100 is in an inclined state after being clamped, the contact reliability between the radiating surface and the radiating surface is affected, and the radiating performance is reduced, so that the unlocking mechanism in the invention needs to ensure that the rotation angles of the first compression bar and the second compression bar are consistent after the first compression bar and the second compression bar reach the unlocking angle, and can realize complete unlocking of the unlocking disc 610, and the three unlocking conditions enable the installation process not to be limited by the operation angle, and finally can realize the relative parallel installation of the adapter body 100 and the radiating surface, and the radiating surface are contacted reliably, and the radiating effect is better.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
