Embodiment
Fig. 1 is the calcspar of the heat radiation proving installation of one embodiment of the invention.The heat radiation proving installation of present embodiment is suitable for being disposed at a cabinet (not shown).Please with reference to Fig. 1, heat radiation proving installation 100 comprises heater element 110_1～110_n, radiator fan 120, detecting control module 130, and wherein n is the positive integer greater than 0.
In the present embodiment, heater element 110_1～110_n can be central processing unit, South Bridge chip, north bridge chips, storer etc.Radiator fan 120 is in order to dispel the heat to heater element 110_1～110_n, so that reduce the temperature of heater element 110_1～110_n.
Detecting control module 130 couples the import 140 of heater element 110_1～110_n and radiator fan 120 and cabinet, in order to the temperature of detecting heater element 110_1～110_n, to obtain equilibrium temperature.In the present embodiment, equilibrium temperature for example is in a period of time, and the variation of temperature degree that detecting control module 130 detects heater element 110_1～110_n surpasses the temperature of preset range.For instance, suppose that the temperature of preset range is ± 0.5 degree, and the temperature that detecting control module 130 was detected is respectively 50.3,50.1,49.9,49.8,50 degree in 5 seconds, therefore, detecting control module 130 can be with 50 degree as equilibrium temperature.
In addition, detecting control module 130 can produce according to equilibrium temperature and control signal to radiator fan 120, with the rotating speed of adjustment radiator fan 120.That is to say, when detecting control module 130 detects equilibrium temperature greater than preset temperature, then produce and control signal to radiator fan 120, to increase the rotating speed of radiator fan 120.So, just, can reduce the temperature of heater element 110_1～110_n.In the present embodiment, increasing the mode that the rotating speed of radiator fan 120 can stepping increases.For instance; The rotating speed of radiator fan can increase 10% of maximum rated rotating speed at every turn; That is to say that this moment, the rotating speed of radiator fan 120 was 50% of a maximum rated rotating speed, and detecting control module 130 outputs control signals to radiator fan 120; Be adjusted into 60% of maximum rated rotating speed with the rotating speed with radiator fan, all the other are then analogized.But present embodiment does not limit 10% of the maximum rated rotating speed of each increase, and also visual demand is adjusted voluntarily, repeats no more at this.
For instance, suppose that preset temperature is that 50 degree, preset value are 20 degree for fully loaded (being that heater element carries out work with 100% usefulness), preset environment temperature, and the rotating speed of radiator fan 120 turns round with 50% of maximum rated rotating speed.When detecting control module 130 detects equilibrium temperature is 65 degree when (being that equilibrium temperature is greater than preset temperature), can produce control signal and give radiator fan 120, and the rotating speed of radiator fan 120 is adjusted into 60% of maximum rated rotating speed.Afterwards; Detecting control module 130 can be detected the temperature of heater element 110_1～110_n once more; At this moment; It is 60 degree (being that equilibrium temperature is greater than preset temperature) that detecting control module 130 detects equilibrium temperature, then produces and controls signal to radiator fan 120, and the rotating speed of radiator fan 120 is adjusted into 70% of maximum rated rotating speed.

Because heater element 110_1～110_n has the situation of fully loaded (for example heater element carries out work with 100% usefulness) and underload (for example heater element does not carry out work with 100% usefulness) when work.Therefore, when detecting control module 130 was judged equilibrium temperature smaller or equal to preset temperature, whether the load that can detect heater element 110_1～110_n was preset value (for example for fully loaded).
If detecting the load of heater element 110_1～110_n is preset value, detecting control module 130 can detect and judge whether the temperature of the import 140 of cabinet is preset environment temperature.When the temperature that detects the import 140 of detecting cabinet is when presetting environment temperature, detect control module 130 and can export test result to a display unit (not shown), so that inform the situation that the user tests.That is, under the load of the heater element 110_1～110_n situation of temperature for preset environment temperature 20 degree for the import 140 of fully loaded and cabinet, radiator fan 120 can be effectively be reduced to safe scope with the temperature of heater element 110_1～110_n.
In addition; If detecting control module 130 judges that equilibrium temperature is greater than preset temperature; And when the rotating speed of radiator fan 120 is maximum rated rotating speed; Detecting control module 130 can produce a warning message to display unit (not shown), informing that the above-mentioned radiator fan of user 120 is not enough to the temperature of heater element 110_1～110_n is reduced in the safe scope, and then changes other radiator fan.Thus, just can increase the test duration of heat radiation test macro, to save human cost.
In addition; If detecting control module 130 judges that the load of heater element 110_1～110_n is not a full load; Then produce the adjustment signal to heater element 110_1～110_n, be adjusted into preset value with load with heater element 110_1～110_n after, and carry out above-mentioned heat radiation testing process once more.If it is not that then generation adjustment signal is adjusted to preset environment temperature with the temperature of the import 140 of cabinet, and carries out above-mentioned heat radiation testing process once more when presetting environment temperature that detecting control module 130 is judged the temperature of the import 140 of cabinet.
Through the above embodiments, can conclude a kind of method of testing of the proving installation 100 that dispels the heat.Fig. 2 is the method for testing process flow diagram of the heat radiation proving installation of one embodiment of the invention.Please with reference to Fig. 2, at step S202, the temperature of detecting heater element is to obtain an equilibrium temperature.
