In the case where the control module 300 is detached from the second installation space 120, it indicates that the control module 300 is in a non-operating state, so that the control chip is in a non-operating state, i.e., the control chip does not need to be cooled, and at this time, the damper 210 is in a wind shielding position, and the damper 210 isolates the first installation space 110 from the second installation space 120, so as to block the air flow generated by the fan 400 from flowing from the first installation space 110 to the second installation space 120.

And during the process of detaching the control module 300 from the second installation space 120, at least a part of the structure of the damper 210 moves in the second installation space 120 toward the partition 130, so that the damper 210 in the wind shielding position can shield the vent 131 of the partition 130 in the area corresponding to the damper 210, thereby preventing the airflow in the first installation space 110 from flowing from the vent 131 into the second installation space 120. Meanwhile, the partition 130 can facilitate connection with an adjacent structure, so that the adjacent structure can be conveniently fixed.

The electronic device disclosed in the embodiment of the present application improves the structure of the electronic device in the related art, and by additionally providing the air duct control mechanism 200 in the electronic device, and by movably arranging the air door 210 in the air duct control mechanism 200 in the device housing 100, the air door 210 can be switched between the air guiding position and the wind shielding position. Under the condition that the control module 300 is detachably installed in the second installation space 120, the control chip on the control module 300 is in an operating state, that is, the control chip can emit more heat at a higher temperature, and at this time, the damper 210 is located at the air guiding position, so that the damper 210 can guide the airflow generated by the fan 400 from the first installation space 110 to the control chip to cool the control chip. The air door 210 in the technical scheme that this application adopted can exert the guide effect to the air current that fan 400 produced to can avoid the air current that fan 400 produced to blow to the control chip comparatively intensively, and then can solve the lower problem of utilization ratio to fan 400.

In the electronic device disclosed in the embodiment of the present application, the air duct control mechanism 200 may further include a transmission mechanism 500, the transmission mechanism 500 is disposed inside the device housing 100, and the transmission mechanism 500 is connected to the air door 210, so that the air door 210 can be switched between the wind shielding position and the wind guiding position along with the transmission mechanism 500. In a case where the control module 300 is detachably mounted in the second mounting space 120, the control module 300 is detachably inserted in the second mounting space 120; during the process of inserting the control module 300 into the second installation space 120, the control module 300 can drive the transmission mechanism 500 to drive the damper 210 to switch from the wind shielding position to the wind guiding position through the cooperation with the transmission mechanism 500.

Under the above situation, in the process that the control module 300 is inserted into the second installation space 120, the control module 300 can be matched with the transmission mechanism 500, so as to drive the transmission mechanism 500, and meanwhile, as the transmission mechanism 500 is connected with the air door 210, the driven transmission mechanism 500 can drive the air door 210 to be switched from the wind shielding position to the wind guiding position, so as to prepare for the heat dissipation and cooling of the control chip on the control module 300. In other words, the above-mentioned solution can fully utilize the process of inserting the control module 300 into the second installation space 120, so that the control module 300 can drive the air door 210 to move to the air guiding position through the transmission mechanism 500, and a power source is not required to be specially configured to drive the air door 210 to move to the air guiding position, thereby reducing energy consumption, and being beneficial to reducing components in the electronic device to reduce the cost of the electronic device and reduce the occupation of space.

Optionally, the electronic device may include a driving mechanism, the driving mechanism is connected to the air door 210, and when the control module 300 is inserted into the second installation space 120, it indicates that the control chip needs to operate and generate heat, and at this time, the driving mechanism may be used to drive the air door 210 to switch from the wind shielding position to the wind guiding position; on the contrary, in the case where the control module 300 is detached from the second installation space 120, the damper 210 may be driven to be switched from the wind guiding position to the wind shielding position by the driving mechanism.

In another alternative solution, a first magnetic member may be disposed on the control module 300, and a second magnetic member may be disposed on the damper 210, where the first magnetic member and the second magnetic member have opposite magnetism, so that during the process of inserting the control module 300 into the second installation space 120, a magnetic attraction force is generated between the first magnetic member and the second magnetic member, so that the position of the damper 210 can be changed, so that the damper 210 can be switched from the wind shielding position to the wind guiding position when the control module 300 is inserted into the second installation space 120, and conversely, during the process of detaching the control module 300 from the second installation space 120, as the distance between the first magnetic member and the second magnetic member increases, the magnetic attraction force between the first magnetic member and the second magnetic member becomes weak, so that the control module 300 no longer has an attraction effect on the damper 210, and the damper 210 can return to the wind shielding position. Of course, one of the damper 210 and the control module 300 may be provided with a third magnetic component, and the other may be provided with a metal component, so that the third magnetic component and the metal component can cooperate with each other to realize the switching of the damper 210 between the wind shielding position and the wind guiding position.

In the above situation, during the process of inserting the control module 300 into the second installation space 120, the connecting end portion 350 of the control module 300 contacts the driven end portion 510, that is, the user can insert the control module 300 to drive the driven end portion 510, so that the driven end portion 510 can drive the damper 210 to move, that is, the driven end portion 510 can drive the damper 210 to move from the wind shielding position to the wind guiding position. The above-mentioned drive is through installation control module 300 and the pure mechanical fit's that produces air door 210 drive mode, and above-mentioned drive mode convenient operation just is favorable to promoting the stability to air door 210 drive, and the installation operation of make full use of control module 300 drives simultaneously, need not to dispose power unit specially.

In the electronic device disclosed in the embodiment of the present application, when the driving damper 210 is switched from the wind guiding position to the wind shielding position, that is, the resetting of the damper 210 may also provide a mechanically-matched implementation manner, specifically, the transmission mechanism 500 may further include an elastic resetting member 520, the elastic resetting member 520 elastically connects the device housing 100 and the driven end portion 510, and in a case that the driven end portion 510 is separated from the connecting end portion 350, the elastic resetting member 520 may drive the driven end portion 510 to rotate, so that the transmission mechanism 500 drives the damper 210 to move from the wind guiding position to the wind shielding position. In this case, when the control module 300 is separated from the driven end 510, the driven end 510 loses the restriction effect from the connecting end 350 of the control module 300, and at this time, the elastic restoring member 520 can drive the driven end 510 by its own elastic driving force, so that the driven end 510 rotates, and the driven end 510 drives the damper 210 to move from the wind guiding position to the wind shielding position.

In a more specific technical solution, the transmission mechanism 500 may further include a first gear 531, a first rotating shaft 532, a second gear 533, and a second rotating shaft 534, the first gear 531 is fixedly sleeved on the first rotating shaft 532, the second gear 533 is fixedly sleeved on the second rotating shaft 534, the first gear 531 is engaged with the second gear 533, the driven end 510 is fixedly connected with the first rotating shaft 532, the air door 210 is fixedly connected with the second rotating shaft 534, during the insertion of the control module 300 in the second installation space 120, the connecting end 350 contacts with the driven end 510 to generate a driving force on the driven end 510, the driven end 510 drives the first rotating shaft 532 to rotate, so that the first rotating shaft 532 can drive the first gear 531 to be engaged with the second gear 533 along the first direction, the second gear 533 rotates along the second direction, the first direction is opposite to the second direction, the second rotating shaft 534 rotates towards the second direction under the driving of the second gear 533, thereby driving the air door 210 to rotate towards the second direction, and further enabling the air door 210 to rotate to the air guiding position.

On the contrary, when the driven end 510 loses the driving force applied by the connecting end 350 of the control module 300 during the process of detaching the control module 300 from the second mounting space 120, the driving force in the opposite direction, i.e., the driving force in the second direction, is applied to the driven end 510, so that the damper 210 can be rotated from the wind guiding position to the wind blocking position. In the above scheme, the driven end 510 and the damper 210 are driven by a gear, optionally, the driven end can also be driven by a chain, and the application does not specifically limit the driving mode between the driven end 510 and the damper 210.

In order to enable the transmission mechanism 500 to be conveniently connected with the equipment housing 100, the transmission mechanism 500 may further include a first fixing block 535 and a second fixing block 536, the first fixing block 535 may be disposed at both ends of the first rotating shaft 532, the first rotating shaft 532 is rotatably connected with the first fixing block 535, the second fixing block 536 may be disposed at both ends of the second rotating shaft 534, the second rotating shaft 534 is rotatably connected with the second fixing block 536, and the first fixing block 535 and the second fixing block 536 are fixedly connected with the equipment housing 100, so that the first rotating shaft 532 and the second rotating shaft 534 are respectively connected with the equipment housing 100 through the first fixing block 535 and the second fixing block 536, thereby facilitating the connection between the first rotating shaft 532 and the second rotating shaft 534 and the equipment housing 100, and further implementing the indirect connection between the damper 210 and the equipment housing 100.

In the electronic device disclosed in the embodiment of the present application, a notch 310 may be formed at a corner of the control module 300, the connecting end portion 350 may be disposed in the notch 310, and in a case where the control module 300 is detachably mounted in the second mounting space 120, the driven end portion 510 is located in the notch 310 and contacts the connecting end portion 350. Under the condition, the connection end part 350 and the driven end part 510 can be matched in the gap 310, so that the matching degree between the connection end part 350 and the driven end part 510 can be improved, the control module 300 and the transmission mechanism 500 can be matched stably, and meanwhile, the gap 310 can reduce the occupation of the space of the electronic device by the matching of the connection end part 350 of the control module 300 and the transmission mechanism 500.

In a further aspect, the driven end 510 has a contact surface 511 that is at an acute angle to the plugging travel path, so that the driven end 510 is more easily accessible to the control module 300 during plugging, the contact surface 511 being in contact with an edge of the connecting end 350. In this case, during the insertion of the control module 300 into the second installation space 120, the edge of the connecting end portion 350 can contact the contact surface 511 of the driven end portion 510, so that the mechanical force generated during the insertion of the control module 300 can be transmitted to the driven end portion 510, so that the driven end portion 510 can transmit the force to the damper 210, and the driven end portion 510 can drive the damper 210 to rotate. The acute angle is advantageous to increase the rotation stroke, and further, is advantageous to enable the control module 300 to drive the driven end 510 as early as possible.

In the electronic device disclosed in the embodiment of the present application, there may be a plurality of control modules 300, a plurality of air duct control mechanisms 200, and a plurality of dampers 210, and the control modules 300 are matched with the dampers 210 in a one-to-one correspondence manner. In this case, the electronic device has a plurality of second installation spaces 120, and the plurality of control modules 300 can be respectively and detachably installed in the plurality of second installation spaces 120, so that the plurality of control modules 300 can be simultaneously installed in the electronic device, and heat dissipation and cooling of the control chips on the plurality of control modules 300 can be simultaneously achieved through cooperation between the plurality of control modules 300 and the plurality of dampers 210.

Meanwhile, in order to increase the structural strength of the electronic device and minimize the influence of the partition 130 on the ventilation between the first installation space 110 and the second installation space 120, the device case 100 may include a plurality of strip-shaped partitions 130, each of the plurality of strip-shaped partitions 130 may be provided with a plurality of ventilation holes 131, and the plurality of partitions 130 may be spaced apart from each other, so that a communication opening 140 may be formed between edges of two adjacent partitions 130. In a case where the plurality of control modules 300 are detached from the second installation space 120, the first set of dampers 210 of the plurality of dampers 210 block the communication openings 140, the second set of dampers 210 of the plurality of dampers 210 are opposite to the partition 130 and block the ventilation holes 131, and the number of the first set of dampers 210 may be greater than the number of the second set of dampers 210, so that in a case where the plurality of control modules 300 are all detachably installed in the second installation space 120, the airflow in the first installation space 110 can flow into the second installation space 120 through the communication openings 140 to cool down the control chips along the dampers 210.

Of course, the number of the control modules 300 detachably installed in the second installation space 120 can be installed according to the use requirement, when only the control module 300 of the installation part is installed, the corresponding damper 210 of the part is located at the wind guiding position, and the dampers 210 in the second installation space 120 where no control module 300 is installed are located at the wind shielding position, so that the damper 210 at the wind shielding position can block the airflow generated by the fan 400 and blow out, and further the airflow generated in the fan 400 can be all blown out from the damper 210 at the wind guiding position, and further the control chip inserted in the second installation space 120 can be cooled by concentrated heat dissipation, so as to achieve sufficient utilization of the airflow generated by the fan 400.

In the electronic device disclosed in the embodiment of the present application, the control module 300 may further include a module holder 320 and a circuit board 330, the circuit board 330 is disposed on the module holder 320, the control chip is mounted on the circuit board 330 and electrically connected to the circuit board 330, the module holder 320 has a supporting function for the circuit board 330 and the control chip, the first end of the damper 210 is movably connected to the device housing 100, the second end of the damper 210 is a free end, in a case that the control module 300 is detachably mounted in the second mounting space 120, the module holder 320 is detachably connected to the device housing 100, and the free end of the damper 210 is located in an area of the circuit board 330 and is close to the control chip. In this case, in the case that the control module 300 is detachably installed in the second installation space 120, the free end of the damper 210 can guide the airflow generated in the fan 400 to a position close to the control chip more specifically, so as to be more favorable for cooling the control chip, and the free end in the area of the circuit board 330 can also guide the airflow to the circuit board 330 at the same time, so as to cool the circuit board 330.

It should be noted that, the rotatable angle of the free end of the air door 210 can be set according to the specific position of the control chip mounted on the circuit board 330 in the actual production, that is, the air door 210 disclosed in this application can adaptively cool and dissipate heat of the control chip. The present application does not specifically limit the mounting position of the control chip on the circuit board 330 and the rotatable angle of the free end of the damper 210.

In a further aspect, the control chip may have a square structure, and in the case where the control module 300 is detachably mounted in the second mounting space 120, the damper 210 is inclined with respect to both the length direction and the width direction of the control chip, and the free end of the damper 210 is adjacent to one corner of the control chip.

Under the condition, because the equipment shell 100 can be provided with the induced air opening, the induced air opening can be arranged at the position opposite to the other corner of the control chip, and the position relation between the other corner and one corner can be diagonal, so that at the air guiding position of the air door 210, the free end of the air door 210 can guide the air flow generated by the fan 400 to one corner of the control chip.

In order to improve the effectiveness of the damper 210 in guiding the airflow to the control chip, in a specific embodiment, the control module 300 may further include a limiting member 340, the limiting member 340 is mounted on the circuit board 330, and the damper 210 is in limiting fit with the limiting member 340 when the control module 300 is detachably mounted in the second mounting space 120. In this case, the limiting member 340 can limit the air guiding position of the damper 210, so that the damper 210 can be limited to a better position for guiding the air flow to the control chip. The specific position of the limiting member 340 mounted on the circuit board 330 may be specifically designed according to the mounting position of the control chip, and the application is not limited thereto.

In order to improve the heat dissipation efficiency of the control chip, the electronic device disclosed in the embodiment of the present application may further include a heat dissipation assembly, the heat dissipation assembly may include a plurality of heat dissipation fins 610 that are parallel to each other, and the plurality of heat dissipation fins 610 are all disposed on the control chip, in this case, heat on the control chip may be transferred to the plurality of heat dissipation fins 610, because the airflow driven by the fan 400 may be guided to the heat dissipation fins 610 through the air door 210, and the heat dissipation fins 610 have a relatively large contact area with the air, the control chip may be intensively cooled in a more targeted manner after the fan 400 is combined with the heat dissipation fins 610, and thus the heat dissipation performance of the control chip may be improved by the plurality of heat dissipation fins 610, and the control chip may be cooled down more quickly.

To improve the heat exchange efficiency of the heat sink 610, in a further aspect, in a state where the control module 300 is detachably mounted in the second mounting space 120, the free end of the damper 210 is adjacent to one corner of the heat sink assembly, and the damper 210 is disposed non-parallel to the heat sink 610. In this case, when the damper 210 guides the airflow to the heat sink 610, since the damper 210 is not parallel to the heat sink 610, the flow direction of the airflow is not parallel to the arrangement direction of the heat sink 610, and thus the damper 210 can be prevented from being disposed parallel to the heat sink 610, the airflow is directly blown through the passages between the plurality of heat sinks 610 parallel to each other with respect to the flow direction of the airflow, so that the airflow and the heat sink 610 cannot be brought into relatively sufficient contact. That is to say, in the present application, the non-parallel arrangement of the damper 210 and the heat sink 610 can increase the collision between the air flow and the heat sink 610, so that the air flow can be in contact with the heat sink 610 sufficiently, and the heat exchange efficiency of the heat sink 610 can be improved.

The electronic equipment disclosed in the embodiment of the application can be specifically a splicing controller, and can also be electronic equipment such as a radiator, and the application does not limit the specific types of the electronic equipment.
