Compared with the prior art, the radiator fan has the following beneficial effects that in the process that the radiator fan rotates at the heat dissipation rotating speed, the radiator fan rotates at the faster dust removal rotating speed at regular time, dust in the radiator is removed, and the situation that the dust is accumulated into blocks for a long time and consequently an air channel is blocked is avoided.

Description

Technical Field

[0001] The present invention relates to the field of heat dissipation of electronic devices, and particularly to an automatic control method for an air-cooled radiator. Background Art

[0002] In modern electronic devices, air-cooled radiators are widely used. They generate airflows by the rotation of fans to accelerate the dissipation of heat from the radiator fins, ensuring that key components inside the electronic devices can operate stably in a suitable temperature environment. When the fan intakes air, it will bring dust into the radiator. The dust accumulates continuously and gradually forms lumps, adhering to the air inlet end of the fins, blocking the air duct between the fan and the fins, resulting in a reduction in the air flow rate entering the fins, a decrease in the heat dissipation efficiency of the radiator, an increase in the internal temperature of the electronic device, and affecting the service life and stability of the device. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic control method for an air-cooled radiator, which can improve the problem of dust accumulation during the operation of the air-cooled radiator, avoid the air duct being blocked due to dust accumulation into lumps, and improve the heat dissipation efficiency to ensure the reliable operation of the device.

[0004] To solve the above technical problem, the present invention provides an air-cooled radiator control method, including a heat dissipation step: making the radiator fan operate at a heat dissipation rotation speed to dissipate heat from the circuit. The feature is that the heat dissipation is timed, and when the timing reaches the preset heat dissipation duration, a dust cleaning step is executed: making the radiator fan operate at a dust cleaning rotation speed higher than the heat dissipation rotation speed to clean dust.

[0005] Further, if it is known that the circuit stops working, the heat dissipation timing is stopped; if it is known that the stopped circuit resumes working, the heat dissipation timing is continued.

[0006] Further, the execution condition of the heat dissipation step includes: knowing that the circuit starts to work.

[0007] Further, the heat dissipation rotation speed is 3000 - 5000 rpm, and / or the dust cleaning rotation speed is 15000 - 30000 rpm.

[0008] Further, the heat dissipation rotation speed is 5000 rpm, and / or the dust cleaning rotation speed is 15000 rpm.

[0009] Further, the preset heat dissipation duration is 120 - 200 hours, and / or the duration for which the radiator fan operates at the dust cleaning rotation speed is 2 - 6 minutes.

[0010] Further, the preset heat dissipation duration is 150 hours, and / or the duration for which the radiator fan operates at the dust cleaning rotation speed is 3 minutes.

[0011] Further, after the dust cleaning step ends, the heat dissipation step is immediately executed again.

[0012] The present invention also provides a computer program product, including a computer program, which is executed by a processor to implement the steps of the above control method.

[0013] The present invention also provides an industrial personal computer, including a circuit, where an air-cooled radiator is connected to the circuit for air-cooling the circuit, and a controller is provided in the circuit to control the connection of the air-cooled radiator. The controller includes a processor and a memory, and the memory stores the above computer program product.

[0014] The automatic control method for the air-cooled radiator provided by the present invention has the following beneficial effects: during the process of the radiator fan rotating at the heat dissipation speed, the radiator fan is periodically made to rotate at a faster dust cleaning speed to clean the dust inside the radiator, avoiding the blockage of the air duct caused by the long-term accumulation of dust into lumps. Detailed implementation manners

[0015] The following further elaborates on the present invention in detail in combination with specific implementation manners.

[0016] The industrial personal computer includes a circuit and an air-cooled radiator controlled by the circuit. A controller is provided in the circuit to control the connection of the air-cooled radiator to dissipate heat from the circuit. The controller includes a processor and a memory connected to each other. The memory stores a computer program product, including a computer program, which when executed by the processor implements the following steps:

[0017] When the controller learns that the circuit starts to work, it executes the heat dissipation step: making the radiator fan rotate at a heat dissipation speed of 3000 - 5000 rpm to dissipate heat from the circuit. In this embodiment, the heat dissipation speed is preferably 5000 rpm. The controller times the heat dissipation. When the heat dissipation timing reaches the heat dissipation preset duration of 120 - 200 hours, in this embodiment, the heat dissipation preset duration is preferably 150 hours, the controller executes the dust cleaning step: making the radiator fan rotate at a dust cleaning speed of 15000 - 30000 rpm. In this embodiment, the dust cleaning speed is preferably 15000 rpm, and the heat dissipation fan rotates at the dust cleaning speed for a duration of 2 - 6 minutes. In this embodiment, the duration of rotation at the dust cleaning speed is preferably 3 minutes. The dust cleaning speed is higher than the heat dissipation speed, which can blow away the dust inside the radiator, avoiding the long-term accumulation of dust into lumps, and the air duct will not be blocked.

[0018] After the dust cleaning step ends, the controller resumes the heat dissipation step to dissipate heat from the circuit. When the heat dissipation timing reaches 150 hours, the dust cleaning step is executed, and so on in a cycle.

[0019] In the heat dissipation step, if the controller learns that the circuit stops working, it stops the heat dissipation timing; if it learns that the stopped circuit resumes working, it resumes the heat dissipation timing to accumulate the heat dissipation time.

[0020] As described above, this is only an implementation mode of the present invention, and does not limit the scope of patent protection. Those skilled in the art make non-substantive changes or substitutions based on the present invention, and still fall within the scope of patent protection.
