Fig. 1 is a schematic diagram illustrating a first exemplary configuration of a heat dissipation assisting device supporting coupling with an electronic device according to an embodiment of the present invention; as shown in fig. 1, the auxiliary heat sink 10 includes a connector 101 and a shield 102 connected to the connector 101; wherein,
when the auxiliary heat sink is coupled to the electronic device, the shielding member 102 is fixed to an outlet port of a heat dissipation channel in the electronic device to induce a medium flow of the heat dissipation channel.
The shielding element 102 is used for supporting and forming a passage with the connecting element 101, so that the passage generates a first electric signal representing the medium flow, and the electronic equipment sends out prompt information according to the first electric signal.
Wherein the medium flow comprises at least a flow rate and/or a flow volume; the media flow may also include direction.

Wherein the shield 102 has a generally porous structure for filtering solid media in the heat sink channel.
In one embodiment, the shield 102 is attached to the housing by a wedge-shaped rubber pad.
In one embodiment, the cover may be configured as a plastic bracket. Wherein the cover may further comprise a hole; the porous substance can be dust proof foam or mylay.
In an example, as shown in fig. 2, the cover 30 configured as a plastic bracket is schematically illustrated in cooperation with a front panel of a chassis of an electronic device; specifically, the same opening area, opening size and opening shape are kept at the air inlet position of the front panel of the case so as to match with the drawing of external air and form a whole with the case.
In still another example, as shown in fig. 3, the perforated area of the cover 30, i.e. the air inlet, is added with a Mesh301 with smaller aperture to play a role of dust prevention; further, a wedge-shaped Rubber gasket Rubber303 is used at the joint of the cover 30 and the front panel of the chassis, which is arranged as a Plastic bracket Plastic crack 302, so as to play an effective fixing role. Therefore, the cover body is flexibly disassembled from the air inlet position of the front panel of the case, so as to achieve the purpose of regularly disassembling and cleaning accumulated dust at the air inlet position.
For the traditional system heat dissipation design scheme aiming at the electronic equipment, because the front panel of the case is provided with the holes, and meanwhile, the fan is used to cause dust accumulation in the system, the dust accumulation of the computer main board can make the heat dissipation difficult, the temperature in the case can rise, and the computer can cause the problems of low heat dissipation efficiency, reduced service life, increased failure rate, reduced service life of the fan or increased system noise and the like under the high-temperature working state for a long time.

Fig. 4 is a schematic diagram of a second exemplary embodiment of a heat dissipation auxiliary heat dissipation device supporting coupling with an electronic device; as shown in fig. 4, the auxiliary heat sink 10 includes a connector 101 and a shield 102 connected to the connector 101; wherein,
the shielding member 102 may be a spring plate with an open pore structure; the connector 101 may include a conductor 1011, a conductive wire 1012 connected to the shield 102, and a conductor structure 1013 that deforms under an external force; wherein the conductor structure 1013 may be provided as a spring.
Here, when the heat dissipation auxiliary heat sink is coupled with the electronic device, the shielding member 102 is fixed to an outlet port of a heat dissipation channel in the electronic device to induce a medium flow of the heat dissipation channel; the shielding element 102 is used for supporting and forming a passage with the connecting element 101, so that the passage generates a first electric signal representing the medium flow, and the electronic equipment sends out prompt information according to the first electric signal.
Wherein the medium flow comprises at least a flow rate and/or a flow volume; the media flow may also include direction. Correspondingly, the auxiliary heat dissipation device generates a first electric signal capable of representing the flow rate corresponding to the medium flow through the passage formed by the shielding piece 102 and the connecting piece 101; or, the auxiliary heat sink generates a first electrical signal capable of representing the flow rate corresponding to the medium flow through the passage formed by the shielding element 102 and the connecting element 101; or, the auxiliary heat dissipation device generates a first electrical signal capable of representing the flow speed and direction corresponding to the medium flow through the passage formed by the shielding piece 102 and the connecting piece 101; alternatively, the auxiliary heat sink generates a first electrical signal capable of representing the flow rate and direction corresponding to the medium flow through the passage formed by the shielding member 102 and the connecting member 101.
In an embodiment, in case the initial state of the channel is conductive, the channel will generate a different first electrical signal in response to the change of the medium flow.
Here, when the initial state of the passage is on, the passage is opened when the medium flow decreases to a predetermined speed threshold.
In yet another embodiment, the shield induces the media flow to create an induced force on the shield in the event the initial state of the passageway is open; the path is conducted under the action of the induction force; the path will generate a different first electrical signal as the flow of the medium changes.
Here, when the initial state of the passage is an open circuit, the passage is turned on when the medium flow decreases to a predetermined speed threshold value.
In one example, as shown in fig. 4, the conductor structure 1013 may be a spring with a suitable elastic coefficient; the shielding member 102 may be a spring plate with an opening structure. The elastic sheet is perpendicular to wind, the area is S, the wind speed is V, and the volume V of air blown onto the area S is equal to Svt within time t; according to the density knowledge, m ═ ρ Svt can be obtained; assuming that the speed of the wind encountering the obstacle is reduced to 0, the generated pressure is F; from the momentum theorem, it can be seen that since Ft is (ρ Svt) v, the average acting force F is generatedWind power＝ρSv2。
Under the specific condition of fan rotational speed, the amount of wind through the clean cover body will give the shell fragment certain power of blowing for the shell fragment removes along the wind direction, thereby drives the spring and produces the displacement, and the spring displacement can produce pressure or pulling force and F promptlytanKx; when the force is equal to FWind powerWhen equal, the stress balance is finally achieved, namely Ftan＝kx＝ρSv2It can be seen that x becomes smaller as the wind speed v becomes smaller.
When the initial state of the path is on, the electronic device enters a power-on self-test stage, the wind speed v is a fixed value, the spring and the elastic sheet are in contact with each other, as shown in fig. 5, when the wind speed is higher than a critical point, such as 80% of the initial system, x ═ 0 is just met, that is, the elastic sheet is just in contact with the conductor 1011 through the connected wire 1012, that is, the path is still in a critical on state, and an electric signal does not need to be triggered to send to the super input/output chip SIO in the electronic device; as shown in fig. 6, when the wind force is lower than the critical point and the medium flow is reduced to the preset speed threshold, the spring ejects the elastic sheet out of the contact area, at this time, the path is switched from the on state to the off state, the first electric signal is triggered to the SIO, and the first electric signal is transmitted to the diagnoses display screen or other devices and apparatuses on the front panel of the electronic chassis, so as to remind the user that the cover body needs to be cleaned at this time.
Of course, in practical applications, a certain margin may be reserved for setting parameters such as a critical point corresponding to the wind power and a preset speed threshold. Meanwhile, the spring ejects the elastic sheet out of the contact area, at the moment, the path is switched from a conducting state to an open circuit state, the process from the first electric signal to the SIO is triggered, the time delay can be kept, namely, the process from the first electric signal to the SIO is triggered only after the path is switched to the open circuit state and lasts for a period of time, so that the electronic equipment sends out prompt information according to the first electric signal to remind a terminal user of timely cleaning dust.
Therefore, the auxiliary heat dissipation device for heat dissipation can sense the medium flow of the heat dissipation channel according to the outlet port of the heat dissipation channel, the shielding piece is stably fixed in the electronic equipment, and a first electric signal representing the medium flow is generated through a passage formed by the shielding piece and the connecting piece, so that the electronic equipment sends prompt information according to the first electric signal to accurately remind a user of timely cleaning the cover body, and the problem of heat dissipation safety regulation caused by the influence of system air inlet after the cover body is blocked after the cover body is used for a period of time is effectively avoided. In addition, because the physical property of the spring is not changed by the change of the environmental factors such as humidity and temperature, the auxiliary heat dissipation device for heat dissipation is guaranteed to be free from the influence of the environmental factors such as humidity and temperature in the process of generating the first electric signal representing the medium flowing through the passage formed by the shielding piece and the connecting piece, so that a user is accurately reminded of timely cleaning the cover body, and the influence of misoperation and industrial and mining of the user is avoided.

Meanwhile, the spring ejects the elastic sheet out of the contact area, at the moment, the path is switched from a conducting state to an open circuit state, the process from the first electric signal to the SIO is triggered, the time delay can be kept, namely, the process from the first electric signal to the SIO is triggered only after the path is switched to the open circuit state and lasts for a period of time, so that the electronic equipment sends out prompt information according to the first electric signal to remind a terminal user of timely cleaning dust.
In practical applications, the auxiliary heat sink 10 and the main body 201 share a power supply in the main body 201; alternatively, the auxiliary heat sink 10 is provided with its own power supply.
In another embodiment, as shown in fig. 9, an obtaining unit 2013 is further disposed in the body 201; wherein,
the acquiring unit 2013 is used for acquiring the rotating speed of the fan;
the processing unit 2012 is further configured to determine a medium flow of the heat dissipation channel in the body according to the fan rotation speed and the first electrical signal.
Here, since the fans have different rotation speeds for the electronic devices, different wind speeds v are generated in the case where the rotation speeds of the fans are different. Therefore, in the process of determining the medium flow of the heat dissipation channel in the body according to the first electrical signal, the processing unit 2012 in the electronic device needs to sufficiently combine the fan rotation speed acquired by the acquisition unit 2013 to accurately determine the medium flow of the heat dissipation channel in the body.
In practical applications, the detecting unit 2011, the processing unit 2012 and the obtaining unit 2013 may be implemented by a processor in the electronic device 20; for example, in practical applications, the electronic device 20 may be implemented by a Central Processing Unit (CPU), a Microprocessor (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like; in addition, the detection unit 2011 may also be implemented by a super input/output chip SIO in the electronic device 20.
In this way, with the electronic device according to the embodiment of the present invention, the detection unit 2011 is used to detect the first electrical signal; after detecting the first signal sent by the auxiliary heat dissipation device 10, the processing unit 2012 determines the medium flow of the heat dissipation channel in the body according to the first electrical signal, and when the medium flow meets the preset condition, the processing unit sends a prompt message to accurately remind the user of timely cleaning the cover body, thereby effectively avoiding the problem that the cover body influences the heat dissipation safety regulation caused by the air inlet of the system after being blocked for a period of time. Further, the fan rotating speed is obtained through the obtaining unit 2013, the medium flowing of the heat dissipation channel in the body is determined by the processing unit 2012 according to the fan rotating speed and the first electric signal, and when the medium flowing meets a preset condition, a prompt message is sent out, so that a user can be accurately reminded to clean the cover body in time under the condition that the fan provides different rotating speeds.
