The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, a method for detecting abnormal heat dissipation of an air duct disclosed in an embodiment of the present invention is used for detecting whether abnormal heat dissipation of an air duct exists, and includes:

Acquiring the temperature T ₁ of the air inlet end of each heating module radiating through the air channel to be detected and the temperature T ₂ of the air outlet end of each heating module, thereby obtaining the actual measurement temperature difference delta T between the air inlet end and the air outlet end of each heating module;

When delta T _a＜ΔT≤ΔT_b is reached, prompting that the heating module is a heat dissipation abnormal module;

when delta T is larger than delta T _b, warning the heating module to be a heat dissipation failure module;

Wherein Δt _a is a temperature difference safety threshold value corresponding to the heating module itself; deltaT _b is the temperature difference alarm threshold value corresponding to the heating module;

the total number of the heat dissipation abnormal modules is M, the total number of the heat dissipation failure modules is N, the total number of the heating modules which conduct heat dissipation through the air duct to be detected is Z, and if N is more than 0 and (M+N)/Z is more than i, the heat dissipation abnormality of the air duct to be detected is judged.

It should be noted that, the measured temperature difference Δt is generally obtained by subtracting the temperature T ₁ of the air inlet end from the temperature T ₂ of the air outlet end; corresponding to the temperature difference, delta T _a and delta T _b are also obtained by the difference between the temperature of the air outlet end and the temperature of the air inlet end of the corresponding heating module; those skilled in the art will appreciate that Δt may be obtained by subtracting the temperature T ₂ of the air outlet from the temperature T ₁ of the air inlet, and Δt _a and Δt _b may be adaptively changed accordingly.

It should be understood that Δt _a and Δt _b may be related to various factors in the determining process, and need to be determined reasonably by comprehensively considering the power of the heat generating module, the flow rate of air in the air duct, the air flow rate, the input voltage, the output voltage, and the ambient temperature, or a calculation function is prefabricated in the control system, the calculation is performed through the above parameters, or a reference table is prefabricated in the control system, and Δt _a and Δt _b corresponding to the current working state of the heat generating module are determined by means of table look-up.

The number of the heating modules radiating through the air duct to be detected may be one or more (n represents an integer greater than 2 in fig. 1), and the detection method is applicable no matter how many the heating modules are, but it should be emphasized that, due to different specific device types and working principles of each heating module, Δt _a and Δt _b are correspondingly different, and the measured temperature difference Δt of each heating module should be compared with the corresponding Δt _a and Δt _b.

The temperature T ₁ at the air inlet end of the heating module should be usually close to the air inlet 1, for example, a temperature sensor may be disposed at a position corresponding to the air inlet 1 and the heating module to obtain the temperature T ₁ at the air inlet end of the heating module; or the temperature sensor can be arranged at the windward end of the heating module for acquiring the temperature of the air inlet end of the heating module; the temperature T ₂ at the air outlet end of the heating module should be usually close to the air outlet 2, for example, a temperature sensor may be disposed at a position corresponding to the air outlet 2 and the heating module to obtain the temperature T ₂ at the air outlet end of the heating module; or the temperature of the air outlet end of the heating module can be obtained, and the temperature sensor can be arranged at the lee end of the heating module.

It should be emphasized that Δt _a and Δt _b should be matched with the temperature T ₁ of the air inlet end and the temperature T ₂ of the air outlet end of the heat generating module, for example: if the temperature sensor is arranged at the position corresponding to the heating module and the air inlet 1 to obtain the temperature T ₁ of the air inlet end of the heating module, and the temperature sensor is arranged at the position corresponding to the heating module and the air outlet 2 to obtain the temperature T ₂ of the air outlet end of the heating module, the delta T _a should be the temperature difference safety threshold value corresponding to the two temperature obtaining positions of the heating module; delta T _b should be the temperature difference alarm threshold value corresponding to the two temperature acquisition positions of the heating module.

I is a proportional value, which can be adjusted according to the air duct, for example, i can be 30% in some cases.

As can be seen from the above embodiments, for any heating module, when the measured temperature difference Δt between the air inlet end and the air outlet end exceeds the corresponding temperature difference safety threshold and does not exceed the corresponding temperature difference alarm threshold, the heating module is prompted as a heat dissipation abnormal module; when the actually measured temperature difference delta T exceeds the temperature difference alarm threshold value corresponding to the heating module, the temperature difference delta T is warned to be a heat dissipation failure module, and further, when the heat dissipation failure module exists and the total number of the heat dissipation abnormal modules and the heat dissipation failure module exceeds a preset proportion i, the heat dissipation of the air duct to be detected at the moment is proved to be problematic, and the air duct to be detected is judged to be abnormal in heat dissipation at the moment. The staff can learn the wind channel that needs to handle fast according to this judgement result to can in time clear up the filter screen 11 of the wind channel that has the heat dissipation unusual, guarantee the normal heat dissipation function in wind channel.

Referring to fig. 1, after the heat dissipation state of each heat generating module is determined, the number of heat dissipation abnormal modules and heat dissipation failure modules needs to be counted, and on the basis of determining that the air duct is abnormal in heat dissipation, N/Z is greater than 0 and less than or equal to x, or i < (m+n)/Z is greater than or equal to h, a primary warning operation mode is entered, where the primary warning operation mode may include, but is not limited to, controlling the heat dissipation abnormal modules to enter a primary low-power mode, and/or controlling the heat dissipation failure modules to enter a safe operation mode, so as to reduce the heat generation amounts of the heat dissipation abnormal modules and the heat dissipation failure modules, where x and h are also proportional values, where the range of values of x and h can be adjusted according to the air duct, for example, in some cases, x can take 20% and h can take 50%.

In embodiments of the present invention, the safe operation mode includes, but is not limited to, stopping the operation of the heat dissipation failure module, or operating the heat dissipation failure module in a safe power state without heat dissipation.

When x is less than N/Z and less than y or h is less than (M+N)/Z is less than g, judging that the air duct is abnormal in heat radiation, and entering a secondary warning operation mode, wherein the secondary warning operation mode indicates that the air duct is blocked seriously, the secondary warning operation mode can comprise but is not limited to controlling the heat radiation abnormal module to enter a secondary low-power mode and/or controlling the heat radiation failure module to enter a safe operation mode so as to reduce the heat quantity of the heat radiation abnormal module and the heat radiation failure module, the power of the heat radiation abnormal module in the secondary low-power mode is lower than that of the heat radiation abnormal module in the primary low-power mode, the purpose of the heat radiation abnormal module is to be further reduced, y and g are also proportional values, the value range of the heat radiation abnormal module can be adjusted according to the air duct, for example, y can be 50% and g can be 80% in some cases.

When y is less than N/Z or g is less than (M+N)/Z, the air duct is indicated to be abnormal in heat dissipation, the air duct is blocked very seriously, and a three-level warning operation mode is entered at the moment, wherein the three-level warning mode can be used for controlling all heating modules to enter a safe operation mode so as to avoid damage to equipment or fire disaster.

Furthermore, in the three-level warning mode, an air duct maintenance alarm can be sent out so as to remind a worker to immediately maintain the air duct.

Under the condition that N=0 and M/Z is less than or equal to i, the air duct part is blocked, but the air duct heat dissipation capacity is still good, and the air duct heat dissipation can be judged to be normal at the moment.
