Then, judge whether to need to carry out temperature control mechanism, allow computer installation can obtain best balance in temperature and usefulness in step 36; If do not need to carry out temperature control mechanism, then get back to step 31; If need to carry out temperature control mechanism, carry out temperature control mechanism in step 37, get back to step 31 after the end.
Fig. 4 is the second embodiment process flow diagram of temperature-controlled process of the present invention.Among the figure, this temperature-controlled process is applicable to electronic installation as shown in Figure 1.Step 41 obtains the power consumption estimated value with lookup table mode.For example, the power consumption estimated value in corresponding this initial temperature interval is found from power consumption temperature corresponding tables 152 (for example tables two) again in default initial temperature interval.Then, detect the running burden of first processing unit 11 and second processing unit 12 in step 42.Adjust the power consumption pattern of first processing unit 11 and second processing unit 12 according to detected running burden in step 43.
Whether total power consumption of step 44 detection. electronics is greater than the power consumption estimated value, if greater than the power consumption estimated value, represent that then the power consumption mode adjustment that step 43 is carried out is not preferable as yet, so re-execute the power consumption pattern that step 43 is readjusted first processing unit 11 and second processing unit 12, be lower than the power consumption estimated value up to total power consumption of electronic installation 1.Then, judge in step 45 whether the temperature of electronic installation has reached need and improved the heat radiation grade.In this step, observe step 43 adjustment result and whether cause temperature to rise.If judge and need not improve the heat radiation grade, then execution in step 47; If judge to need improve the heat radiation grade, then execution in step 46 is selected higher temperature range, re-executes step 41 again and tables look-up and obtain new power consumption estimated value, further dynamically to adjust the power consumption pattern of first processing unit 11 or second processing unit 12.
Judge in step 47 whether the temperature of electronic installation 1 has reached and need to reduce the heat radiation grade,, then postpone behind the Preset Time execution in step 45 again if judge and do not need to reduce the heat radiation grade; Need to reduce the heat radiation grade if judge, the usefulness and the temperature of electronic installation 1 have then been taken into account after the power consumption pattern of expression adjustment first processing unit 11 and second processing unit 12 effectively, so select lower temperature range in step 48, then judge whether to need to continue this temperature control in step 49, for example can first preset temperature control start threshold value, if temperature still starts threshold value greater than temperature control at present, then judge and continue this temperature control, execution in step 41; Otherwise, then finish this temperature control.
The above only is for example, but not limitation of the present invention.Anyly do not break away from spirit of the present invention and category and, all should be contained in the scope of the present invention its equivalent modifications of carrying out or change.
