Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a heat dissipation control method. Background Technology

[0002] For a closed-loop HS radiator installed in the system, the cooling process basically consists of two parts: one part is that the internal pump provides driving force to the system, so that the coolant flows and carries away the heat from the power components; the other part is that the heat from the radiator is carried away by the fan in the system.

[0003] Closed-loop heatsinks have been used for cooling in recent generations of tower PCs, but to ensure their cooling efficiency, the power applied to the pumps driving the coolant within the tower PC remains essentially unchanged. However, for server applications, constantly keeping the pumps at full load results in significant power waste. Summary of the Invention

[0004] This invention provides a heat dissipation control method to optimize the power consumption of liquid cooling pumps, reduce the overall system power consumption, and achieve energy saving.

[0005] This invention provides a heat dissipation control method applicable to liquid-cooled servers comprising a liquid-cooled pump and a computing element. The method includes: determining the operating temperature and current load power of the computing element; selecting a first target relation from a plurality of first pre-stored relational expressions based on the operating temperature, wherein each of the first pre-stored relational expressions corresponds to a plurality of first temperature ranges; determining a first duty cycle of the liquid-cooled pump based on the operating temperature and the first target relational expression; selecting a second target relation from a plurality of second pre-stored relational expressions based on the operating temperature, wherein each of the second pre-stored relational expressions corresponds to a plurality of second temperature ranges; determining a second duty cycle of the liquid-cooled pump based on the operating temperature and the second target relational expression; determining a target duty cycle of the liquid-cooled pump based on the current load power, the idle load power of the computing element, the full load power of the computing element, the first duty cycle, and the second duty cycle; and controlling the operation of the liquid-cooled pump based on the target duty cycle.

[0006] The above technical solution can control the heat dissipation of a liquid-cooled server containing a liquid-cooled pump and computing elements. By determining the operating temperature of the computing elements and the current load power, a target relation is selected from multiple pre-stored relational formulas. When determining whether the computing elements are at idle or full load power, the optimal first / second duty cycle of the liquid-cooled pump is determined for different operating temperatures. The target duty cycle of the liquid-cooled pump is then determined based on the current load power, the first duty cycle, and the second duty cycle. This optimizes the power consumption of the liquid-cooled pump, reduces the overall system power consumption, and achieves energy saving.

[0024] Figure 1 A schematic diagram of the structure of a liquid-cooled server is provided for an embodiment of the present invention. For example... Figure 1 As shown, the liquid-cooled server 100 includes a cold plate 1, a liquid cooling pump 2, a first liquid cooling pipe 31 and a second liquid cooling pipe 32, a heat sink 4, a fan module 5, and a controller 6. The cold plate 1 is used to dissipate heat from computing components (such as a processor). The liquid cooling pump 2 is mounted on the cold plate 1 and provides power for the flow of cooling liquid. The first liquid cooling pipe 31 connects the cold plate 1, the liquid cooling pump 2, and the heat sink 4. The second liquid cooling pipe 32 connects the two sets of cold plates 1 and liquid cooling pump 2, forming a liquid cooling circuit. The heat sink 4 is used for heat exchange with the heated cooling liquid. The fan module 5 provides airflow to the heat sink 4 to accelerate the heat exchange rate. The controller 6 is connected to the liquid cooling pump 2 and the fan module 5 and controls the first power of the liquid cooling pump 2 and the second power of the fan module 5. The controller 6 can control the first power by controlling the first working cycle of the liquid cooling pump 2, and control the second power by controlling the second working cycle of the fan module 5. The sum of the first power and the second power can be referred to as the heat dissipation power consumption of the liquid-cooled server 100.

[0025] The controller 6, for example, is a microcontroller, a programmable logic controller, or other component or component integration with computing and control functions, and can provide the heat dissipation control method provided by the present invention to control the liquid cooling pump 2. The controller 6 can be connected to the computing element to determine the operating temperature of the computing element through the temperature sensor of the computing element itself, or it can be connected to a voltage sensor that senses the voltage of the computing element and a current sensor that senses the current of the computing element to determine the current load power of the computing element, or it can be connected to another temperature sensor to obtain the ambient temperature of the server.

[0026] Figure 2 A flowchart illustrating a heat dissipation control method provided in an embodiment of the present invention. Figure 2 As shown, the heat dissipation control method includes: S11: determining the operating temperature of the computing element and the current load power; S12: selecting a first target relation from multiple first pre-stored relational expressions based on the operating temperature; S13: determining a first working cycle of the liquid cooling pump based on the operating temperature and the first target relational expression; S14: selecting a second target relation from multiple second pre-stored relational expressions based on the operating temperature; S15: determining a second working cycle of the liquid cooling pump based on the operating temperature and the second target relational expression; S16: determining a target working cycle of the liquid cooling pump based on the current load power, the idle load power of the computing element, the full load power, the first working cycle, and the second working cycle; S17: controlling the operation of the liquid cooling pump based on the target working cycle.

[0027] In step S11, the controller can acquire the operating temperature and current load power of the computing element through a temperature sensor, a voltage sensor, and a current sensor. In step S12, the controller can select a first target relation from multiple first pre-stored relational expressions based on the operating temperature of the computing element, wherein each of the multiple first pre-stored relational expressions corresponds to a multiple first temperature range. Specifically, the first pre-stored relational expression can describe the relationship between the operating temperature of the computing element and the required duty cycle of the liquid cooling pump. In step S13, the controller can determine a first duty cycle of the liquid cooling pump based on the first target relational expression to dissipate heat from the computing element at a specific operating temperature. In step S14, the controller can select a second target relation from multiple second pre-stored relational expressions based on the operating temperature of the computing element, wherein each of the multiple second pre-stored relational expressions corresponds to a multiple second temperature range. In step S15, the controller can determine a second duty cycle of the liquid cooling pump based on the second target relational expression to dissipate heat from the computing element at a specific operating temperature. It should be noted that step S14 is essentially the same as step S12. The multiple first pre-stored relations in step S12 correspond to the first load power of the computing element, and the multiple second pre-stored relations in step S14 correspond to the second load power of the computing element.

[0028] Figure 3 This is a flowchart illustrating the determination of the target operating cycle in the heat dissipation control method provided for the implementation of this invention. (Example:) Figure 3 As shown, step S16 includes: step S161: determining a first difference between the current load power and the idle load power, and a second difference between the full load power and the idle load power; step S162: dividing the first difference by the second difference, and determining the quotient as a specific ratio value; step S163: determining a third difference between the second working cycle and the first working cycle; step S164: determining the sum of the product of the third difference and the specific ratio value and the first working cycle as the target working cycle.

[0029] In step S161, the controller subtracts the idle load power from the current load power of the computing element to obtain a first difference, and subtracts the idle load power from the full load power of the computing element to obtain a second difference. The current load power is between the idle load power and the full load power; therefore, the first difference is generally greater than zero and less than the second difference. When the current load power equals the idle load power, the first difference is zero; when the current load power equals the full load power, the first difference and the second difference are equal. In step S162, the controller divides the first difference by the second difference to obtain a quotient value between 0 and 1, and determines this quotient value as a specific proportion. Through steps S161 and S162, the controller determines the specific proportion of the current load power between the idle load power and the full load power.

[0030] In step S163, the controller can determine a third difference between the second operating cycle and the first operating cycle, where the first operating cycle corresponds to the idle state where the computing element has idle load power, and the second operating cycle corresponds to the full-load state where the computing element has full load power. In step S164, the controller can determine the target operating cycle of the liquid cooling pump by summing the product of the third difference and a specific ratio value with the first operating cycle. In other words, through steps S163 and S164, the controller performs linear interpolation on the first and second operating cycles based on a specific ratio value to determine the target operating cycle. The target operating cycle can be expressed as Formula 1:

[0031]

[0032] Where LPP(OT,CP) is the target work cycle, LPP(OT,CP)| cp＝pidle For the first working cycle, LPP(OT,CP)| cp＝pTDP This is the second duty cycle, where CP represents the current load power, and P... idle For idle load power, P TDP This represents the full load power.

[0033] Figure 4 A flowchart for generating the first pre-stored relational expression in the heat dissipation control method provided in the embodiments of the present invention, such as... Figure 4 As shown, the controller of the liquid-cooled server can execute the following steps: Step S21: Control the computing element to operate at idle load power; Step S22: When the liquid cooling pump is running in the first default working cycle, determine the first relationship curve between the total power of the liquid cooling pump and the fan and the thermal margin value of the liquid-cooled server; Step S23: When the liquid cooling pump is running in the second default working cycle, determine the second relationship curve between the total power of the liquid cooling pump and the fan and the thermal margin value of the liquid-cooled server, wherein the second default working cycle is longer than the first default working cycle; Step S24: Determine the minimum temperature corresponding to the first relationship curve as the first temperature; Step S25: Determine the temperature corresponding to the intersection of the first relationship curve and the second relationship curve as the second temperature; Step S26: Generate multiple first pre-stored relational expressions based on the first default working cycle, the second default working cycle, the first temperature, and the second temperature.

[0034] In step S21, the idle load power is the load power of the computing element in its idle state. In step S22, the liquid cooling pump is set to a first default duty cycle among multiple default duty cycles, for example, the multiple default duty cycles are 20%, 40%, 60%, 80%, and 100%, with the first default duty cycle being 20%. When the duty cycle of the liquid cooling pump is determined, the power of the liquid cooling pump is also determined. Next, the controller can adjust the power consumption of the fan module and determine the relationship curve between the thermal margin value of the liquid-cooled server and the overall heat dissipation power consumption.

[0035] Figure 5 This is a graphical diagram illustrating multiple relationship curves in the heat dissipation control method provided in an embodiment of the present invention. For example... Figure 5 As shown, data C1 corresponds to the first curve showing the relationship between the thermal margin value and heat dissipation power consumption of the liquid-cooled server under the condition that the liquid cooling module's duty cycle is 20%. With increasing heat dissipation power consumption, a larger thermal margin value can be provided to the liquid-cooled server, enabling heat dissipation for computing components operating at higher temperatures.

[0036] In step S23, the liquid cooling pump is set to a second default operating cycle (e.g., 40% of the operating cycle), and the second operating curve corresponding to data C2 is obtained. In steps S24 and S25, the minimum operating temperature of the computing element corresponding to the first relationship curve can be defined as the first temperature T1, and the operating temperature of the computing element corresponding to the intersection of the first and second relationship curves can be defined as the second temperature T2. In this embodiment, data C1 to C5 are the first to fifth relationship curves corresponding to different operating cycles. That is, steps similar to step S23 can be executed multiple times to obtain multiple relationship curves, which will not be elaborated here. In addition to the first temperature T1, the remaining second temperature T2, third temperature T3, fourth temperature T4, and fifth temperature T5 are all temperatures corresponding to the intersection of two adjacent relationship curves. That is, steps similar to step S25 can be executed multiple times to obtain the temperatures corresponding to the intersection of multiple relationship curves, which will not be elaborated here.

[0037] Taking the first relationship curve, the second relationship curve, and the second temperature T2 as examples. When the operating temperature of the computing element is the second temperature T2, the liquid-cooled server has the same overall heat dissipation power consumption when using a heat dissipation scheme with a 20% or 40% duty cycle for the liquid cooling pump. When the operating temperature of the computing element is between the first temperature T1 and the second temperature T2, the liquid-cooled server has less heat dissipation power consumption when using a 20% duty cycle for the liquid cooling pump than when using a 40% duty cycle. When the operating temperature of the computing element is above the second temperature T2, the liquid-cooled server has less heat dissipation power consumption when using a 40% duty cycle for the liquid cooling pump than when using a 20% duty cycle. Therefore, this embodiment obtains the pre-stored relationship formulas for the duty cycles of different temperature ranges by linearly interpolating the default duty cycle. In step S26, multiple first pre-stored relationship formulas can be generated based on multiple default duty cycles and multiple temperatures at the intersection points. Corresponding to Figure 5 Multiple first-pre-stored relations can be expressed as Formula 2:

[0038]

[0039] Where TMV represents the operating temperature minus the ambient temperature of the liquid-cooled server, i.e., the thermal margin value; T1 to T5 represent the first to fifth temperatures; and LPP1 to LPP5 represent the first to fifth default operating cycles.

[0040] It should be noted that this embodiment uses five default working cycles to determine five relationship curves and four corresponding intersection points. In other embodiments, the number of default working cycles can also be adjusted, and this case does not impose any restrictions.

[0041] Steps S21 to S26 described above can also be applied to cases where the computing element has other load power, i.e., the controller of the liquid-cooled server can perform the following: control the computing element to operate at full load power; when the liquid cooling pump is operating in the first default duty cycle, determine a first relationship curve between the total power of the liquid cooling pump and the fan and the thermal margin value of the liquid-cooled server; when the liquid cooling pump is operating in the second default duty cycle, determine a second relationship curve between the total power of the liquid cooling pump and the fan and the thermal margin value of the liquid-cooled server, wherein the second default duty cycle is longer than the first default duty cycle; determine the minimum temperature corresponding to the first relationship curve as the first temperature; determine the temperature corresponding to the intersection of the first relationship curve and the second relationship curve as the second temperature; and generate multiple second pre-stored relationships based on the first default duty cycle, the second default duty cycle, the first temperature, and the second temperature.

[0042] Through the above steps, a second pre-stored relationship between the operating temperature of the computing element under full load power conditions and the duty cycle of the liquid cooling pump can be determined. Multiple second pre-stored relationships are expressed in the same form as multiple first pre-stored relationships, i.e., in the form of Formula 2. Other descriptions of steps S21 to S26 that are identical or similar are omitted here.

[0043] Figure 6 This is a flowchart illustrating the determination of a first target relationship in the heat dissipation control method provided in an embodiment of the present invention. For example... Figure 6 As shown, step S12, which selects the first target relation from the pre-stored relation, includes: Step S121: Determine whether the difference between the operating temperature and the ambient temperature is less than a first temperature; if so, proceed to step S122; otherwise, proceed to step S123; Step S122: The first target relation uses a first default working cycle as the first working cycle; Step S123: Determine whether the difference between the operating temperature and the ambient temperature is greater than a second temperature; if so, proceed to step S124; otherwise, proceed to step S125; Step S124: The first target relation uses a second default working cycle as the first working cycle; Step S125: The first target relation determines the first working cycle by linearly interpolating the first default working cycle and the second default working cycle.

[0044] When the controller determines that the difference between the operating temperature of the computing element and the ambient temperature is less than the first temperature T1, the first target relation uses the first default working cycle (LPP1) as the first working cycle. When the controller determines that the difference between the operating temperature of the computing element and the ambient temperature is not greater than the second temperature T2, the first target relation determines the first working cycle by linearly interpolating the first default working cycle (LPP1) and the second preset working cycle (LPP2).

[0045] It is important to note that when the controller determines that the difference between the operating temperature and the ambient temperature is greater than the second temperature T2, it can further determine the relationship between the operating temperature and the third temperature T3, the fourth temperature T4, and the fifth temperature T5 to determine which temperature range the operating temperature falls within. Furthermore, the target relationship is a linear interpolation of the two default operating cycles corresponding to the two extreme temperatures within the temperature range in which the operating temperature lies. For example, when the operating temperature minus the ambient temperature falls between the third temperature T3 and the fourth temperature T4, the first target relationship determines the first operating cycle by linearly interpolating the third default operating cycle (LPP3) and the fourth preset operating cycle (LPP4).

[0046] Similarly, step S14, which selects the second target relation from the pre-stored relation, includes steps that are essentially the same as steps S121 to S125, namely: determining whether the difference between the operating temperature and the ambient temperature is less than the first temperature; if so, the second target relation uses the first default operating cycle as the second operating cycle; if not, determining whether the difference between the operating temperature and the ambient temperature is greater than the second temperature; if so, the second target relation uses the second default operating cycle as the second operating cycle; if not, the second target relation determines the second operating cycle by linearly interpolating the first and second default operating cycles. Other descriptions of steps S121 to S125 that are identical or similar are omitted here.

[0047] The above technical solution can control the heat dissipation of a liquid-cooled server containing a liquid-cooled pump and computing elements. By determining the operating temperature of the computing elements and the current load power, a target relation is selected from multiple pre-stored relational formulas. When determining whether the computing elements are at idle or full load power, the optimal first / second duty cycle of the liquid-cooled pump is determined for different operating temperatures. The target duty cycle of the liquid-cooled pump is then determined based on the current load power, the first duty cycle, and the second duty cycle. This optimizes the power consumption of the liquid-cooled pump, reduces the overall system power consumption, and achieves energy saving.
