[0091] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
[0092] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.
[0093] The electronic components within a vehicle's domain controller generate heat during operation, causing the temperature of the circuit boards to rise continuously. When the circuit board's surface temperature falls below the ambient dew point, condensation forms, and this condensation drips onto the circuit board, potentially causing component failure. Furthermore, when electronic components are exposed to low temperatures, their processing performance decreases and their power consumption increases.
[0094] In order to solve the problems existing in the related art, the present disclosure proposes a temperature control method, device, chip, electronic device and storage medium. In response to the board temperature of the circuit board where the electronic component is located in the controller being lower than the condensation recognition temperature, the refrigeration component is controlled to stop refrigeration, so that the temperature of the surface of the electronic component can be relatively high and will not be lower than the condensation recognition temperature of the environment as much as possible, thereby preventing the occurrence of condensation. In response to the board temperature of the electronic component being greater than or equal to the condensation recognition temperature, the refrigeration component is controlled to refrigerate according to the junction temperature of the electronic component. Refrigeration can be carried out in a timely manner when the junction temperature of the electronic component is high, ensuring that the junction temperature of the electronic component is within an appropriate range, thereby avoiding damage to the electronic component or performance degradation caused by the high junction temperature of the electronic component. In the embodiment of the present application, the working state of the refrigeration component can be dynamically adjusted according to the board temperature and junction temperature of the electronic component, thereby creating a suitable environment for the electronic component, which is not only conducive to ensuring the processing performance of the SOC, but also can extend the life of the electronic component.
[0095] Before introducing the detailed solution of the present disclosure, taking the electronic component as SOC and the cooling component as a semiconductor cooling chip (Thermoelectric Cooler, TEC) as an example, the scenario in which the solution of the present disclosure is applied is first described. Figure 1 This is a schematic diagram of an application scenario provided by an embodiment of the present disclosure. Figure 1 As shown, from top to bottom are a water cooling plate 101, a coolant 102, a thermal conductive adhesive 103, a semiconductor refrigeration sheet (Thermoelectric Cooler, TEC) 104, a low power double data rate memory (Low Power Double Data Rate, LPDDR) 105 and a chip package 106, wherein the heat dissipation structure is mainly used to dissipate heat for the chip package 106.
[0096] Optionally, the chip package 106 may include a plurality of chip units 107 cut from a wafer.
[0097] Optionally, the water cooling plate 101 is used to dissipate heat from the chip package 106 via the cooling liquid 102 .
[0098] Optionally, the coolant 102 is used to flow in the water-cooled plate 101 to remove heat generated when the SOC is working.
[0099] Optionally, thermal conductive adhesive 103 is used to connect the water cooling plate 101 and the TEC 104 , and to connect the TEC 104 and the LPDDR 105 , to assist in conducting heat from the chip package 106 to the water cooling plate 101 .
[0100] Optionally, the TEC 104 includes a hot side and a cold side. The TEC 104 has an active cooling function. When the temperature is high, it can enter a cooling mode to transfer heat from the cold side to the hot side. Specifically, it absorbs heat from the cold side and releases it on the hot side, thereby lowering the temperature of the hot side and providing a lower ambient temperature for the SOC. The TEC 104 also has an active heating function. When the temperature is low, it can enter a heating mode to raise the temperature of the cold side, thereby providing a higher ambient temperature for the SOC. Through both heating and cooling functions, the TEC 104 can provide a suitable ambient temperature for the SOC, thereby improving the processing performance of the SOC. The TEC 104 has two power supply terminals, U+ and U-. Applying a voltage to the TEC 104 via the U+ or U- terminals creates a temperature differential across the cooling block. The voltage direction can optionally cause the TEC 104 to perform either cooling or heating. For example, a voltage provided by the U+ terminal causes the TEC to perform cooling, while a voltage provided by the U- terminal causes the TEC to perform heating.
[0101] Optionally, LPDDR 105 is a low-power dynamic random access memory connected to the chip package 106 .
[0102] When the ambient temperature of the SOC is high, the heat is transferred from the chip package 106 through various components to the water cooling plate 101, and then the heat is taken away by the coolant 102, achieving effective heat conduction, thereby ensuring that the temperature of the SOC is within an acceptable range during operation, preventing the SOC from overheating and causing damage to the SOC. Figure 1 As shown, the heat dissipation direction is indicated by arrows in the figure.
[0103] Optionally, the chip package 106 may include a central processing unit (CPU) and a graphics processing unit (GPU), wherein the CPU is used to schedule and manage all hardware resources and can efficiently handle multiple tasks; the GPU can support multiple 4K ultra-high-definition touch screen displays, realizing the function of one chip and multiple screens, and providing clear and smooth image and video displays for the driver and passengers; it provides powerful processing capabilities for multimedia entertainment, navigation, vehicle information display and other functions of the smart cockpit. While processing multiple high-load tasks in the cockpit, the computing unit will generate a lot of heat. At this time, if there is no heat dissipation mechanism, the performance will be greatly affected.
[0104] Figure 2 This is a flow chart of a temperature control method provided in an embodiment of the present application. Figure 2 As shown, the temperature control method may include but is not limited to the following steps:
[0105] S201, obtaining the board temperature of the circuit board where the electronic components in the controller are located.
[0106] In some embodiments, the controller can be a controller of different electronic devices. Optionally, the electronic device can be a smart phone, a tablet computer, a personal digital assistant, a wearable device, an in-vehicle device or an Internet of Vehicles device, such as a vehicle. In this disclosure, only a vehicle is used as an example, but it does not limit the scope of this disclosure.
[0107] In some embodiments, the controller may be a domain controller of the vehicle. Optionally, the domain controller of the vehicle may include, but is not limited to, a power domain controller, a chassis domain controller, a body domain controller, an intelligent cockpit domain controller, an autonomous driving domain controller, etc.
[0108] In some embodiments, a temperature sensor is disposed on the circuit board where the electronic components are located, and the board temperature of the circuit board where the electronic components are located can be collected based on the temperature sensor. Optionally, one or more temperature sensors can be disposed within a designated area of the circuit board where the electronic components are located. For example, one or more temperature sensors can be disposed in the center area of the circuit board. For another example, one or more temperature sensors can be disposed near the electronic components, for example, multiple temperature sensors can be disposed on the circuit board surrounding the electronic components.
[0109] In some embodiments, when multiple temperature sensors are provided, the temperatures collected by the multiple temperature sensors may be averaged to obtain the board temperature of the circuit board where the electronic components are located.
[0110] In some embodiments, the temperatures collected by multiple temperature sensors may be compared, and the maximum temperature may be selected as the board temperature of the circuit board where the electronic component is located.
[0111] In some embodiments, the types of temperature sensors may include, but are not limited to: thermistor temperature sensors (e.g., negative temperature coefficient (NTC) thermistor sensors), thermocouple temperature sensors, diode-based temperature sensors, integrated circuit temperature sensors, digital temperature sensors, resistance temperature detectors, etc.
[0112] S202 , in response to the board temperature of the circuit board where the electronic components in the controller are located being lower than the condensation recognition temperature, controlling the refrigeration component to stop refrigeration.
[0113] In some embodiments, the condensation recognition temperature can be determined based on the dew point temperature. Alternatively, the condensation recognition temperature can be the dew point temperature. Alternatively, the condensation recognition temperature can be a temperature greater than the dew point temperature, but with a difference from the dew point temperature within a set range. For example, if the dew point temperature is 33°C, the condensation recognition temperature can be determined to be 35°C based on the dew point temperature.
[0114] In some embodiments, the board temperature of the electronic component may be compared with the condensation recognition temperature to determine whether the board temperature of the electronic component is lower than the condensation recognition temperature.
[0115] In some embodiments, the board temperatures of the electronic component obtained a set number of times can be averaged to obtain an average board temperature of the electronic component. The average board temperature of the electronic component can be compared with the condensation recognition temperature to determine whether the average board temperature of the electronic component is lower than the condensation recognition temperature.
[0116] If the temperature of the circuit board where the electronic components in the controller are located is lower than the condensation recognition temperature, the refrigeration component can be controlled to stop refrigeration in order to avoid condensation.
[0117] S203 , in response to the board temperature of the electronic component being greater than or equal to the condensation recognition temperature, performing cooling control on the cooling component according to the junction temperature of the electronic component.
[0118] In some embodiments, when the board temperature of the electronic component is greater than or equal to the condensation recognition temperature, it indicates that the surrounding environment of the electronic component is high. Furthermore, the refrigeration component can enter refrigeration control based on the junction temperature of the electronic component, which can avoid the board temperature of the electronic component being too high or the junction temperature of the electronic component being too high.
[0119] In some embodiments, the junction temperature of the electronic component is the actual operating temperature of the transistor junction inside the electronic component. Optionally, the ambient temperature around the electronic component, the thermal resistance of the electronic component from the junction to the environment, and the power consumption of the electronic component when working can be determined. The junction temperature of the electronic component is determined based on the ambient temperature, the thermal resistance from the junction to the environment, and the power consumption of the electronic component.
[0120] In some embodiments, the junction temperatures of the electronic component acquired a set number of times may be averaged to obtain an average junction temperature of the electronic component. Further, the cooling component may be controlled based on at least one of the average junction temperatures.
[0121] The present disclosure proposes a temperature control method. When the board temperature of the circuit board where the electronic components are located in the controller is lower than the condensation recognition temperature, the refrigeration component is controlled to stop refrigeration, so that the temperature of the surface of the electronic components can be relatively high and will not be lower than the condensation recognition temperature of the environment as much as possible, thereby preventing the occurrence of condensation.
[0122] When the board temperature of the electronic component is greater than or equal to the condensation recognition temperature, the refrigeration component is controlled according to the junction temperature of the electronic component. Refrigeration can be promptly performed when the junction temperature of the electronic component is high, ensuring that the junction temperature of the electronic component is within an appropriate range, thereby avoiding damage to the electronic component or performance degradation caused by the high junction temperature of the electronic component.
[0123] In the embodiment of the present application, the working state of the refrigeration component can be dynamically adjusted according to the board temperature and junction temperature of the electronic components, thereby creating a suitable environment for the electronic components, which is not only conducive to ensuring the processing performance of the SOC, but also can extend the life of the electronic components.

[0145] In some embodiments, the indication information may be a sleep / wake-up indication of the controller.
[0146] In some embodiments, the indication information may be a power-on indication of the controller.

[0148] In some embodiments, the indication information may be generated based on the user's power-on voice or wake-up voice.
[0149] S420: Acquire the board temperature and junction temperature of the electronic components in the controller.
[0150] In some embodiments, after obtaining the board temperature of the electronic component, S430, S440, and S450 may be executed separately. It is understood that when the board temperature of the electronic component satisfies the determination criteria of one step, the subsequent steps of the corresponding branch of the step are executed. That is, when the determination criteria of S430 are met, S431 to S434 may be executed; when the determination criteria of S440 are met, S441 may be executed; and when the determination criteria of S450 are met, S451 to S456 may be executed.
[0151] S430: Determine whether the board temperature of the electronic component is lower than a first set temperature.
[0152] In response to the board temperature of the electronic component being lower than the first set temperature, S431 is executed.
[0153] S431, controlling the refrigeration component to enter a heating mode, and configuring the operating voltage of the refrigeration component to be a first voltage.
[0154] In some embodiments, in response to the electronic component's panel temperature (or average panel temperature) being less than a first set temperature, the cooling assembly is controlled to enter heating mode, where the first set temperature is less than the condensation detection temperature. For example, the first set temperature may be -20°C. This heating mode provides heat to the electronic component, maintaining an ambient temperature for the electronic component, thereby ensuring processing performance of the electronic component.
[0155] It is understandable that when the board temperature (or average board temperature) of the electronic component is lower than the first set temperature, it indicates that the electronic component is in a low temperature environment. In order to ensure the processing performance of the electronic component, the ambient temperature can be raised by heating the refrigeration component.
[0156] Furthermore, to rapidly heat the environment surrounding the electronic components, the refrigeration assembly can be controlled to operate at a higher operating voltage for heating. Optionally, the operating voltage of the refrigeration assembly can be configured to be a first voltage. It should be noted that the first voltage is less than or equal to the maximum allowable voltage of the refrigeration assembly and greater than or equal to a set voltage threshold. This limitation ensures that the operating voltage of the refrigeration assembly is relatively high, thereby enabling rapid temperature rise.
[0157] In some embodiments, the first set temperature is -20°C.
[0158] In some embodiments, the first voltage is the maximum allowable voltage of the refrigeration component. For example, if the operating voltage of the refrigeration component is 0-6V, the maximum allowable voltage is 6V.
[0159] That is, when the board temperature of the electronic component is less than -20°C, the refrigeration component is controlled to enter the heating mode, and the operating voltage of the refrigeration component is configured to be 6V.
[0160] S432: During the heating process of the refrigeration component, the board temperature of the electronic component is continuously monitored.
[0161] S433, determining whether the board temperature of the electronic component rises to a set temperature threshold.
[0162] In some embodiments, while the cooling assembly is operating in heating mode, the board temperature of the electronic component may continue to be monitored. In response to the board temperature of the electronic component rising to a set temperature threshold, step S434 is executed, i.e., the cooling assembly is controlled to end the heating mode and enter the off state. For example, the set temperature threshold is 10°C.
[0163] In response to the board temperature of the electronic component not rising to the set temperature threshold, the refrigeration assembly is controlled to continue the heating mode, that is, S431 is continued to be executed.
[0164] It should be noted that the cooling component enters heating mode for low-temperature heating only once each time the controller is powered on or woken up from sleep mode. When the board temperature of the heated electronic components reaches the set temperature threshold, the cooling component's heating mode will terminate completely until the next power-on instruction or wake-up instruction from sleep mode is received from the controller.
[0165] S434, controlling the refrigeration component to end the heating mode and enter the off state.
[0166] S440: Determine whether the board temperature of the electronic component is greater than or equal to a first set temperature and less than a condensation recognition temperature.
[0167] In response to the board temperature of the electronic component being greater than or equal to the first set temperature and less than the condensation recognition temperature, step S441 is executed.
[0168] S441, controlling the refrigeration component to enter the closed state.
[0169] When the electronic component's board temperature (or average board temperature) is greater than or equal to the first set temperature and less than the condensation detection temperature, the refrigeration component is controlled to be off when the electronic component's board temperature is within a relatively suitable temperature range, thereby saving energy. It is understood that when the electronic component's board temperature (or average board temperature) is greater than or equal to the first set temperature and less than the condensation detection temperature, the temperature of the environment in which the electronic component is located is relatively suitable, will not affect the electronic component's processing performance, and therefore, no refrigeration component is required to generate heat.
[0170] In some embodiments, the condensation recognition temperature is 35°C.
[0171] That is, when the board temperature of the electronic component is -20°C or less than 35°C, the refrigeration component is controlled to enter the closed state.
[0172] S450: Determine whether the board temperature of the electronic component is greater than or equal to the condensation recognition temperature.
[0173] In response to the board temperature of the electronic component being greater than or equal to the condensation recognition temperature, S451 is executed.
[0174] S451, determining whether the junction temperature of the electronic component is a null value.
[0175] In some embodiments, in the controller power-on or sleep wake-up process, the micro control unit (MCU) in the controller is first powered on or woken up. After the MCU is powered on or woken up, the electronic components are powered on or woken up. Before the electronic components are powered on or woken up, the junction temperature of the electronic components cannot be obtained because the electronic components have not entered the standby state, that is, the junction temperature of the electronic components is a null value.
[0176] In response to the junction temperature of the electronic component being a non-null value, step 452 is executed.
[0177] In response to the junction temperature of the electronic component being a null value, step 456 is executed.
[0178] S452, determining whether the junction temperature of the electronic component is greater than or equal to a second set temperature.
[0179] In response to the junction temperature of the electronic component being lower than the second set temperature, step S453 is executed.
[0180] In response to the junction temperature of the electronic component being greater than or equal to the second set temperature, step S454 is executed.
[0181] S453, controlling the refrigeration component to enter the closed state.
[0182] In a scenario where the junction temperature of the electronic component is a non-null value and is lower than the second set temperature, the performance of the SOC will not be affected due to the low junction temperature of the electronic component, and the TEC is controlled to enter a closed state, thereby keeping the TEC closed and saving energy.
[0183] In some embodiments, the second set temperature is 60° C. That is, when the junction temperature of the electronic component is less than 60° C., the refrigeration component is controlled to enter a closed state.
[0184] S454, controlling the refrigeration component to enter the refrigeration mode.
[0185] When the junction temperature of the electronic component is a non-null value and is greater than or equal to the second set temperature, the refrigeration component can be controlled to enter cooling mode to prevent performance degradation or damage to the electronic component due to the high junction temperature. Furthermore, an adaptive operating voltage can be configured based on the actual junction temperature, so that the cooling effect of the refrigeration component is more in line with actual needs and energy conservation can be achieved.
[0186] That is to say, when the junction temperature of the electronic components is ≥60°C, the refrigeration component is controlled to enter the refrigeration state.
[0187] S455 , determining a target temperature range for the junction temperature, and configuring the operating voltage of the cooling component according to the target temperature range.
[0188] In some embodiments, multiple temperature intervals may be included, each temperature interval corresponds to a voltage configuration information. Optionally, the voltage configuration information may be a voltage interval. Optionally, the voltage configuration information may be a voltage.
[0189] In some embodiments, a mapping relationship between temperature intervals and voltage configuration information is pre-built.
[0190] According to the target temperature range, the mapping relationship between the temperature range and the voltage configuration information is queried, and the target voltage configuration information corresponding to the target temperature range is determined according to the mapping relationship. Further, the operating voltage of the refrigeration component is configured according to the target voltage configuration information.
[0191] In some embodiments, in response to the target voltage configuration information including a target voltage interval, the operating voltage of the refrigeration component is configured to be within the target voltage interval; or, in response to the target voltage configuration information including a target voltage, the operating voltage of the refrigeration component is configured to be the target voltage.
[0192] In some embodiments, the operating voltage configured for the cooling component is positively correlated with the target temperature range. That is, as the temperature range increases, the configured operating voltage will gradually increase until it reaches the maximum allowable voltage of the cooling component.
[0193] In some embodiments, the lengths of any two temperature intervals may be the same or different, which is not a condition limiting the present application.
[0194] In some embodiments, the increments of the operating voltages corresponding to adjacent temperature intervals may be the same or different.
[0195] For example, the temperature range T i-1 Corresponding voltage range or voltage V i-1 , temperature range T iCorresponding voltage range or voltage Vi, temperature range T i+1 Corresponding voltage range or voltage V i+1 .
[0196] If the target temperature range is the temperature range T i-1 , then according to the voltage range or voltage V i-1 The operating voltage of the refrigeration component is configured, for example, configured to a first target voltage.
[0197] If the target temperature range is the temperature range T i , then according to the voltage range or voltage V i The operating voltage of the refrigeration component is configured, for example, to be a second target voltage.
[0198] If the target temperature range is the temperature range T i+1 , then according to the voltage range or voltage V i+1 The operating voltage of the refrigeration component is configured, for example, to a third target voltage.
[0199] In some embodiments, the difference between the second target voltage and the first target voltage can be obtained, which can be used as the voltage increment of the operating voltage corresponding to a group of adjacent temperature intervals, namely the second temperature interval and the first temperature interval; the difference between the third target voltage and the second target voltage can be obtained, which can be used as the voltage increment of the operating voltage corresponding to a group of adjacent temperature intervals, namely the third temperature interval and the second temperature interval.
[0200] In some embodiments, the voltage increment of the operating voltage corresponding to one group of adjacent temperature intervals may be the same as or different from the voltage increment of the operating voltage corresponding to another group of adjacent temperature intervals.
[0201] In some embodiments, when the board temperature of the electronic component is greater than or equal to the condensation recognition temperature and the junction temperature of the electronic component is greater than or equal to the second set temperature, the refrigeration component may be controlled according to the junction temperature of the electronic component.
[0202] For example, the first temperature range is [60°C, 65°C], that is, 60°C≤T j <65℃, the operating voltage of the cooling component is 0.5V.
[0203] The second temperature range is 65℃≤T j <70℃, the operating voltage of the cooling component is 1V.
[0204] The third temperature range is 70℃≤T j <75℃, the operating voltage of the cooling component is 1.5V.
[0205] The fourth temperature range is 75℃≤T j<80℃, the operating voltage of the cooling component is 2V.
[0206] The fifth temperature range is 80℃≤T j <85℃, the operating voltage of the cooling component is 3V;
[0207] The sixth temperature range is 85℃≤T j <90℃, the operating voltage of the cooling component is 4.5V;
[0208] The seventh temperature range is T j >90℃, the operating voltage of the TEC cooling component is 6V.
[0209] For example, the voltage increment of the operating voltage corresponding to the first temperature interval and the second temperature interval is 0.5, the voltage increment of the operating voltage corresponding to the second temperature interval and the third temperature interval is 0.5, and the voltage increment of the operating voltage corresponding to the third temperature interval and the fourth temperature interval is 1 V. In other words, the voltage increment of the operating voltage corresponding to one set of adjacent temperature intervals can be the same as or different from the voltage increment of the operating voltage corresponding to another set of adjacent temperature intervals.
[0210] In some embodiments, in response to the operating voltage of the cooling component being configured as the maximum allowable voltage of the cooling component and the junction temperature of the electronic component being greater than or equal to the set junction temperature threshold, that is, when the target temperature range is within the maximum temperature range and the junction temperature of the electronic component exceeds the set junction temperature threshold, the operating frequency of the electronic component is reduced. It is understandable that if the target temperature range is within the maximum temperature range (T j >90°C), and the junction temperature of the electronic component exceeds the set junction temperature threshold (for example, the set junction temperature threshold can be 95°C), it means that the junction temperature of the electronic component is in an extremely high state. In order to avoid high temperature damage to the electronic component, the operating frequency of the electronic component can be reduced while controlling the refrigeration component to cool, thereby achieving the purpose of further reducing the junction temperature of the electronic component.
[0211] S456, controlling the refrigeration component to enter the refrigeration mode, and configuring the operating voltage of the refrigeration component to be the second voltage.
[0212] In some embodiments, since the board temperature of the electronic component is greater than the condensation recognition temperature, it means that the surrounding environment of the electronic component is high, and since the electronic component needs to perform a power-on or wake-up process, it often causes the board temperature of the electronic component to rise. In order to avoid the electronic component from being unable to power on or wake up quickly due to the rise in board temperature, the refrigeration component can be controlled to enter a cooling mode to reduce the board temperature of the electronic component. This not only maintains the responsiveness of the electronic component, allowing the electronic component to be quickly powered on or woken up, but also avoids high-temperature damage.
[0213] Furthermore, the operating voltage of the refrigeration component in the refrigeration mode can be configured. Optionally, the operating voltage of the refrigeration component can be configured to a second voltage. It is understandable that since the current electronic component is in the power-on or wake-up process, it will not generate much heat. A moderate voltage can be configured to meet the refrigeration needs. Optionally, the second voltage is less than or equal to the first voltage. Optionally, the second voltage can be the default operating voltage of the refrigeration component in the refrigeration mode. Optionally, the second voltage is less than the maximum allowable voltage of the refrigeration component.
[0214] In some embodiments, the second voltage is less than the maximum allowable voltage of the refrigeration component, for example, may be 2V.
[0215] That is, when the junction temperature of the electronic component is a null value, the cooling component is controlled to enter the cooling mode, and the operating voltage of the cooling component is configured to be 2V.
[0216] In the disclosed embodiment, the board temperature of the electronic component can be combined with the junction temperature of the electronic component. When the board temperature of the electronic component is lower than the condensation recognition temperature, the refrigeration component can be controlled to stop refrigeration, so that the temperature of the surface of the electronic component can be relatively high and will not be lower than the condensation recognition temperature of the environment as much as possible, thereby reducing the occurrence of condensation. When the board temperature of the electronic component is higher than the condensation recognition temperature, the refrigeration component can be controlled according to the junction temperature of the electronic component. Refrigeration can be carried out in a timely manner when the junction temperature of the electronic component is high, ensuring that the junction temperature of the electronic component is within an appropriate range, thereby avoiding damage to the electronic component or performance degradation caused by the high junction temperature of the electronic component.
[0217] It is understandable that the temperature control method provided in the above embodiment involves electronic components such as SOC in the controller and refrigeration components such as Figure 1 The TEC shown can obtain the board temperature and junction temperature of the SOC, and based on the board temperature and junction temperature of the SOC, the TEC is controlled according to the temperature control method provided in the above embodiment.
