Description

  The present invention relates to a technique for controlling a cooling mechanism for cooling a heat-generating component in an electronic device.

  The electronic device is provided with a cooling mechanism that cools a heat-generating component that generates heat when energized. As a general cooling mechanism, there is a cooling mechanism provided with a heat sink that dissipates heat transmitted from a heat-generating component. In addition, as such a cooling mechanism, there is one having a fan that generates air flowing through the heat sink in order to increase the heat dissipation capability of the heat sink.

  By the way, the heat-generating component described above varies greatly in power consumption depending on the usage status of electronic equipment. Therefore, a cooling control method for controlling the operation of the fan based on the temperature of the heat generating component is well known. Generally, control is performed to increase the rotational speed of the fan when the temperature of the heat-generating component is high and to decrease the rotational speed of the fan when the temperature is low.

  Patent Document 1 discloses a related technique for controlling the operation of a fan. The related art described in Patent Document 1 has a plurality of cooling fans that cool the operating part of the computer system. Further, in this related technology, the supply cooling amount that each cooling fan gives to the operating unit is stored in advance. And this related technique calculates the required cooling amount required for an operation part based on the information regarding the temperature of an operation part. In this related technique, the number of rotations of each cooling fan is determined based on the required cooling amount of the operating part and the supply cooling amount of each cooling fan.

  However, the general fan control method described above and the related technology described in Patent Document 1 have the following problems.

  In a general method for controlling the operation of a fan based on the temperature of a heat generating component, if the number of rotations of the fan is increased in accordance with the temperature increase of the heat generating component, the temperature of the heat generating component is decreased, and therefore the number of rotations of the fan is decreased. . However, under a usage situation in which the load on the heat-generating component is high, when the fan speed decreases, the temperature of the heat-generating component rises again, and control is required to increase the fan speed again. As described above, when the temperature of the heat generating component rises and falls, the control for increasing the rotational speed of the fan increases, which is inefficient in terms of power usage of the fan. In particular, when an upper limit value is set for the temperature of the heat generating component and the cooling control based on the temperature is performed, such inefficient power use becomes significant in a margin region where the temperature of the heat generating component is close to the upper limit value.

  The related art described in Patent Document 1 does not include a heat sink, and determines the rotational speed of the fan without considering the heat sink. Therefore, even if this related technology is applied to a cooling mechanism that cools a heat-generating component using a heat sink, the power consumption of the fan cannot be sufficiently suppressed.

  SUMMARY An advantage of some aspects of the invention is to provide a technique for sufficiently suppressing power consumption of a fan in a cooling mechanism that cools a heat-generating component using a heat sink.

  The cooling control device according to the present invention includes a heat generation unit power acquisition unit that acquires information on power consumption of a heat generation unit that generates heat during operation, and a fan that generates wind that circulates through a heat sink that dissipates heat transmitted from the heat generation unit.

For example, the fan unit 501 may include a motor, a rotating shaft that rotates by rotation of the motor, and a plurality of blades that are radially coupled to the rotating shaft, and may be configured to generate wind by rotation. In this case, the drive control unit 502 may be configured to adjust the rotational speed of the fan unit 501 based on control information from the outside.

As shown in FIG. 3, the cooling control device 10 includes a heat generating unit power acquisition unit 11, a heat sink intake temperature acquisition unit 12, and a fan control unit 13. For example, the heat generating unit power acquisition unit 11 includes a connection interface 104 and a processor 101 that executes a computer program stored in the memory 102. The heat sink intake air temperature acquisition unit 12 includes a connection interface 105 and a processor 101 that executes a computer program stored in the memory 102.

  The heat generation unit power acquisition unit 11 receives information representing power from the power measurement unit 60, and acquires information on the power consumption of the heat generation unit 30 based on the received information. For example, the heat generation unit power acquisition unit 11 may apply the value indicated by the information received from the power measurement unit 60 as it is as the information regarding power consumption.

  The electronic device and the cooling control apparatus according to the first embodiment of the present invention can more sufficiently suppress the power consumption of the fan in the cooling mechanism that cools the heat-generating component using the heat sink.

It is because it acquires. This is because the fan control unit controls the operation of the fan based on the information on power consumption and the information on the heat sink intake temperature.

  Thus, in the present embodiment, the operation of the fan is controlled in consideration of the intake air temperature to the heat sink based on the power consumption of the heat generating portion. As a result, according to the present embodiment, in the cooling mechanism using the heat sink and the fan, it is possible to efficiently suppress the power consumption of the fan as compared with the case where it is simply based on the temperature of the heat generating portion.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In this embodiment, an example in which an information processing device is applied to the electronic device of the present invention and a CPU (Central Processing Unit) is applied to the heat generating portion in the present invention will be described. Note that, in each drawing referred to in the description of the present embodiment, the same reference numerals are given to the same configuration and steps that operate in the same manner as in the first embodiment of the present invention, and the detailed description in the present embodiment. Description is omitted.

  First, FIG. 5 shows a configuration of an information processing apparatus 2 as a second embodiment of the present invention. In FIG. 5, the information processing apparatus 2 includes a cooling control device 20, a CPU 35, a heat sink 40, a fan 50, a power measurement unit 60, and a temperature measurement unit 70. Moreover, each part which comprises the information processing apparatus 2 can be comprised by the hardware element similar to the 1st Embodiment of this invention demonstrated with reference to FIG.

  The cooling control device 20 can be configured by the integrated circuit 100, similarly to the cooling control device 10 in the first embodiment of the present invention.

  The CPU 35 generates heat by energization during the operation of the information processing apparatus 2. Further, the CPU 35 is disposed on a substrate 90 provided inside the housing of the information processing apparatus 2.

  The heat sink 40 can be configured by a heat transfer member 401 and a plurality of heat dissipating members 402 as in the first embodiment of the present invention. In the present embodiment, the heat transfer member 401 is disposed on the heat generating surface of the CPU 35.

  The fan 50 can be configured by a fan unit 501 and a drive control unit 502, as in the first embodiment of the present invention. In the present embodiment, fan section 501 generates wind by rotation. Further, it is assumed that the drive control unit 502 can adjust the rotational speed of the fan unit 501 based on a control signal from the outside. Further, the fan 50 is disposed at a position where the wind generated by the rotation of the fan unit 501 flows between the heat dissipation members 402 of the heat sink 40. 5 shows an example in which the wind generated by the fan 50 is sent toward the heat sink 40, but the direction of the wind generated by the fan 50 is not limited. For example, the fan 50 may generate a wind in a direction of sucking air from the heat sink 40 so that the wind flows between the heat dissipation members 402 of the heat sink 40.

  The electric power measurement part 60 can be comprised by an electric power sensor similarly to the 1st Embodiment of this invention. In the present embodiment, it is assumed that the power measurement unit 60 is provided in the CPU 35. The power measuring unit 60 measures the power consumed by the CPU 35 and outputs it to the cooling control device 20.

  The temperature measuring unit 70 can be configured by a temperature sensor as in the first embodiment of the present invention. For example, when air is sent from the fan 50 toward the heat sink 40, the temperature measurement unit 70 is disposed between the heat sink 40 and the fan 50. Then, the temperature measuring unit 70 measures the temperature of the air sucked into the heat sink 40 and outputs it to the cooling control device 20.

  Next, functional blocks of the cooling control device 20 will be described with reference to FIG. As shown in FIG. 6, the cooling control device 20 is different from the cooling control device 10 according to the first embodiment of the present invention in that a heating unit power acquisition unit 21 and a fan are used instead of the heating unit power acquisition unit 11. The difference is that a fan control unit 23 is provided instead of the control unit 13.

The heat generator power acquisition unit 21 receives information representing power from the power measurement unit 60. And the heat-generation-part electric power acquisition part 21 calculates the value based on the value received from the electric power measurement part 60 by the time as information regarding power consumption. For example, the heat generator power acquisition unit 21 may perform a process of averaging values received from the power measurement unit 60 up to that point. And the heat-generation-part electric power acquisition part 21 is good also considering the value calculated by an averaging process as the information regarding power consumption. For example, the heating unit power acquisition unit 21 may obtain an exponential moving average value by, for example, the following equation (1) as such an averaging process.

Here, the constant α is a smoothing coefficient for smoothing the power consumption value, and 0 <α ≦ 1. α is determined in advance in order to suppress a rapid increase in the rotational speed of the fan 50. The current power value indicates the latest power value obtained from the power measuring unit 60.

The fan control unit 23 calculates information representing the required heat dissipation performance based on information obtained by averaging power consumption, information on the heat sink intake temperature, and a temperature upper limit value allowed for the CPU 35. The required heat dissipation performance refers to the performance required for the heat sink 40. Such necessary heat dissipation performance may be information indicating the thermal resistance required for the heat sink 40. For example, the fan control unit 23 may calculate the necessary heat dissipation performance using the following equation (2).

Here, the temperature upper limit value is an upper limit value of the temperature allowed for the CPU 35. The upper temperature limit is determined in advance depending on the type of the CPU 35.

Further, the fan control unit 23 controls the operation of the fan 50 based on the required heat dissipation performance. For example, as described above, when the fan 50 is configured to generate wind by rotation, the fan control unit 23 determines the required rotation speed of the fan 50 (required fan rotation speed) based on the required heat dissipation performance. . Then, the fan control unit 23 transmits control information indicating the required fan rotation speed to the drive control unit 502 of the fan 50. For example, the fan control unit 23 may obtain the necessary fan rotational speed using the following equation (3).

Here, the constants x, y, and z are values that determine the thermal resistance characteristics of the heat sink 40. The values of these constants are determined in advance depending on the type of the heat sink 40. The fan control unit 23 can determine the required fan rotation speed from the required heat dissipation performance by determining x, y, z and using this equation (3).

  The cooling control operation in the information processing apparatus 2 configured as described above will be described with reference to FIG.

  In FIG. 7, first, the heating unit power acquisition unit 21 receives information representing the power consumption of the CPU 35 from the power measurement unit 60 (step S <b> 11).

  Next, the heat generating unit power acquisition unit 21 calculates information on power consumption based on the power consumption values received from the heat generating unit power acquisition unit 21 up to this point (step S12). For example, as described above, the heat generating unit power acquisition unit 21 may perform the averaging process by obtaining the exponential moving average value using Equation (1).

  Next, the heat sink intake temperature acquisition unit 12 acquires information representing the heat sink intake temperature from the temperature measurement unit 70 (step S13).

  Next, the fan control unit 23 requires the necessary heat dissipation of the heat sink 40 based on the information on the power consumption of the CPU 35 calculated in step S12, the information on the heat sink intake temperature obtained in step S13, and the temperature upper limit value of the CPU 35. The performance is calculated (step S14). For example, as described above, the fan control unit 23 may calculate the necessary heat dissipation performance using the equation (2).

  Next, the fan control part 23 determines a required fan rotation speed based on the required heat dissipation performance calculated by step S14 (step S15). For example, as described above, the fan control unit 23 may calculate the necessary fan rotation speed using the equation (3).

  Next, the fan control unit 23 sends control information based on the required fan rotation speed determined in step S15 to the fan 50 (step S16).

  The information processing apparatus 2 repeats the operations in steps S11 to S16. Above, description of operation | movement of the information processing apparatus 2 is complete | finished.

  Next, the effect of the second exemplary embodiment of the present invention will be described.

  The information processing apparatus and the cooling control apparatus as the second embodiment of the present invention can more sufficiently suppress the power consumption of the fan in the cooling mechanism that cools the CPU using the heat sink.

  The reason is that, in addition to the same configuration as that of the first embodiment of the present invention, the heat generating unit power acquisition unit calculates information representing the power consumption based on the CPU power consumption obtained up to that point. Because it does. For example, the heat generating unit power acquisition unit calculates a value obtained by averaging the power consumption of the CPU obtained up to that point by a calculation formula including a predetermined constant. Then, the fan control unit calculates the required heat dissipation performance required for the heat sink based on the value based on the power consumption of the CPU up to that point, the heat sink intake temperature, and the temperature upper limit value determined for the CPU. Because. This is because the fan control unit determines the necessary fan rotation speed and controls the fan rotation speed by applying the calculated required heat dissipation performance to a calculation formula including a predetermined constant.

  The effect of this embodiment will be described with reference to FIGS. In FIG. 8, the horizontal axis indicates the passage of time. The vertical axis indicates the fan speed or CPU temperature. A solid line arrow schematically shows a change in CPU temperature over time in the present embodiment. A broken arrow schematically shows a change in CPU temperature with time when a general method of controlling the fan speed based on the CPU temperature is used. Moreover, the solid line double arrow schematically shows the time change of the fan rotation speed in the present embodiment. Moreover, the broken double-lined arrow schematically shows the time change of the fan rotation speed when a general control method is used. As shown in FIG. 8, in a general control method, when the temperature of the CPU increases, the rotational speed of the fan increases and the CPU temperature decreases. When the CPU temperature falls, the fan speed decreases and the CPU temperature rises again. Thus, in a general control method, the temperature of the CPU increases and decreases, and the rotational speed of the fan increases and decreases. On the other hand, this embodiment can stabilize the fan rotation speed so as to keep the CPU temperature close to the upper limit value.

  In FIG. 9, the horizontal axis indicates CPU power consumption. The vertical axis indicates the fan speed. A solid line arrow schematically shows a change in the number of fan rotations with respect to the CPU power consumption of the present embodiment. The dashed-dotted arrow schematically shows a change in fan rotational speed with respect to CPU power consumption when a general method of controlling the rotational speed of the fan by a linear method based on the CPU temperature is used. Note that the linear method refers to control for linearly changing the fan rotation speed with respect to the CPU temperature. A broken arrow schematically shows a change in fan rotation speed with respect to CPU power consumption when a general method of controlling the fan rotation speed in a stepwise manner based on the CPU temperature is used. The staircase method refers to control that varies the fan rotation speed with respect to the CPU temperature in a staircase pattern. As shown in FIG. 9, in the present embodiment, the fan can be rotated at a lower speed in the region A than a general control method of a linear method based on the CPU temperature. In the present embodiment, the fan can be rotated at a lower speed in the region B than in a general control method using a staircase method based on the CPU temperature. And since the power consumption of a fan is proportional to a fan rotation speed, this Embodiment can reduce the power consumption of a fan compared with a general control method.
