[0025] With the continuous development of servers, the power consumption of new servers is also increasing, resulting in an increase in the heat generated. Traditional air cooling can no longer meet the heat dissipation requirements of servers. Existing servers generally use liquid cooling systems.
[0026] In the related art, the server cabinet and the liquid cooling circulation device constitute a liquid cooling system. The test and verification process of the liquid cooling system mainly involves manually setting a heat source in the liquid cooling system, starting the liquid cooling system and working for a period of time, and then detecting whether the temperature of the liquid cooling system is lower than the upper limit value, thereby determining whether the liquid cooling system is qualified. However, in the existing verification method of the liquid cooling system, the heat power consumption of the heat source cannot be accurately controlled, resulting in the inability to correctly simulate the heating state of the server, resulting in a relatively low credibility of the verification result.
[0027] The present application provides a control method for a heat dissipation verification device, a heat dissipation verification device and a system for accurately controlling the heat dissipation power consumption of a heat generating module, thereby correctly simulating the heat dissipation state of a server, and thereby improving the credibility of a verification result of a liquid cooling system.
[0028] Please refer to Figure 1 , Figure 1 The present invention provides a block diagram of a heat dissipation verification device 100 , wherein the heat dissipation verification device 100 is used to be arranged in a target liquid cooling system 200 , and the heat dissipation verification device 100 includes a BMC module 110 , a temperature detection module 120 , a switch module 130 and a heating module 140 .
[0029] The temperature detection module 120 is connected to the BMC module 110 (BMC, Baseboard Management Controller), and the switch module 130 is connected to the BMC module 110 and the heating module 140 respectively.
[0030] Next, combine Figure 1 A control method for a heat dissipation verification device provided in an embodiment of the present application is introduced. Figure 2 As shown, the control method of the heat dissipation verification device specifically includes the following steps:
[0031] Step S21: When receiving the verification instruction, the BMC module generates a driving signal according to the verification instruction.
[0032] In the embodiment of the present application, the verification instruction may be sent to the BMC module by an external control device, wherein the external control device may include but is not limited to electronic devices such as computers, tablet computers, and mobile phones. The external control device may establish a communication connection with the heat dissipation verification device, that is, the external control device may establish a communication connection with the BMC module, for example, the external control device may be connected to the heat dissipation verification device through a signal line and establish communication.
[0033] The verification instruction may include heat power consumption, and the BMC module generates a corresponding drive signal according to the heat power consumption so that the heat module can also output the same heat power consumption. For example, the heat power consumption of the server to be simulated is 5 kilowatts, and the BMC module will generate a corresponding drive signal according to the heat power consumption.
[0034] Step S22: the BMC module transmits the driving signal to the switch module, so that the switch module drives the heating module to output the target power.
[0035] In the embodiment of the present application, the BMC module is connected to the control end of the switch module, and the switch module also includes a first end and a second end, the first end is used to receive the power supply energy, and the second end is used to output the power to the heating module. After receiving the driving signal, the switch module can adjust the amount of power output to the heating module according to the driving signal, thereby controlling the heating module to output the target power, that is, the heating module reaches the required simulated heating power consumption.
[0036] Step S23: The BMC module reads the temperature data of the temperature detection module, and obtains the heat dissipation verification result of the target liquid cooling system according to the temperature data.
[0037] It can be understood that after the BMC module controls the output of the target power of the heating module through the driving signal so that the heating module reaches the required simulated heating power consumption in the target liquid cooling system, the temperature data in the target liquid cooling system can be read through the temperature detection module to verify whether the heat dissipation function of the target liquid cooling system is qualified through the temperature data, thereby obtaining the corresponding heat dissipation verification result. Among them, the temperature detection module includes but is not limited to various types of temperature sensors.
[0038] In an embodiment of the present application, by setting a BMC module, a switch module, a heating module and a temperature detection module in a heat dissipation verification device, when the target liquid cooling system is detected and verified, the BMC module generates a corresponding driving signal according to the verification instruction, and transmits the driving signal to the switch module, so that the switch module drives the heating module according to the driving signal, thereby making the heating module output the target power, and then making the heating module reach the required simulated heating power consumption, so that the heat dissipation verification device can accurately simulate the heating state of the server, and then the BMC module can obtain the heat dissipation verification result according to the temperature data with higher reliability.
[0039] In some embodiments, the switch module includes at least one MOS tube (MOS, Metal-Oxide-Semiconductor Field-Effect Transistor), and the heating module includes at least one heating resistor. The MOS tube includes a control end, a first end and a second end, the control end of each MOS tube is connected to the BMC module, the first end of each MOS tube is used to receive power supply energy, and the second end of the MOS tube is connected to the corresponding heating resistor. The step of the BMC module transmitting the drive signal to the switch module includes: outputting the drive signal to at least one MOS tube, so that the MOS tube outputs the target voltage to the corresponding heating resistor according to the drive signal.
[0040] It can be understood that by setting multiple MOS tubes and corresponding heating resistors, the adjustable range of the target power of the heat dissipation verification device can be larger, that is, the adjustable range of the heat consumption of the heat dissipation verification device can be larger, thereby enabling the heat dissipation verification device to simulate the heating status of more types of servers.
[0041] In the embodiment of the present application, the verification instruction includes the above-mentioned target power, which can be understood as follows. Figure 3 As shown, generating a driving signal according to the verification instruction may include:
[0042] Step S31: determining a target conduction frequency and a target duty cycle according to the target power.
[0043] In the embodiment of the present application, the BMC module can extract the target power to be achieved by the heating module from the verification instruction, and determine the target conduction frequency and the target duty cycle of the switch module according to the target power.
[0044] Step S32: generating a driving signal according to the target conduction frequency and the target duty cycle.
[0045] The driving signal includes but is not limited to a PWM signal (PWM, Pulse width modulation), the target conduction frequency is the frequency of the PWM signal, and the target duty cycle is the duty cycle of the PWM signal.

[0048] Step S51: The BMC module receives a verification instruction sent by an external control device through the communication module.
[0049] In the embodiment of the present application, the communication module can be connected to the external control device through a signal line to receive the verification instruction sent by the external control device and forward the verification instruction to the BMC module. Alternatively, the communication module can also be a wireless communication module.
[0050] Step S52: When receiving the verification instruction, the BMC module generates a driving signal according to the verification instruction.
[0051] Step S53: the BMC module transmits the driving signal to the switch module, so that the switch module drives the heating module to output the target power.
[0052] Among them, steps S52-S53 are consistent with the above steps S21-S22 and will not be repeated here.
[0053] Step S54: the BMC module transmits the temperature data to the external control device through the communication module, so that the external control device obtains the heat dissipation verification result of the target liquid cooling system according to the temperature data.
[0054] Please refer to Figure 6 In step S22, obtaining the heat dissipation verification result of the target liquid cooling system according to the temperature data includes:
[0055] Step S61: Determine whether the temperature data is lower than a preset temperature value.
[0056] Step S62: When it is determined that the temperature data is lower than the preset temperature value, the heat dissipation verification result of the target liquid cooling system is obtained to be qualified.
[0057] In the embodiment of the present application, the above-mentioned preset temperature value may be pre-stored in the BMC module, and the heat dissipation verification result obtained by the BMC module may also be transmitted to the above-mentioned external control device.
