Description

Technical Field

[0001] The present disclosure relates to the technical field of electrical dehumidification, and in particular to a heat dissipation device, a heat dissipation control method, a medium and a vehicle of a water-cooled controller. Background Art

[0002] As the electronic and electrical architecture (EEA) of the whole vehicle evolves from distributed to centralized, new requirements are put forward for the functions of the on-board electronic controller. The same controller needs to integrate more functions. For example, corresponding chips will be added inside the controller, which will increase the overall thermal power consumption of the controller and generate more heat. Therefore, water cooling is usually introduced to reduce the heat of the controller. When water cooling is introduced into the controller, in some operating conditions, the coolant temperature in the cooling water circuit will be lower than the ambient temperature and the dew point temperature corresponding to the ambient temperature, thereby generating condensed water on the controller cavity, threatening the circuit safety and the service life of electronic components.

[0003] To this end, the prior art mainly uses temperature control to prevent the controller from reaching condensation conditions. For example, the temperature of the coolant in the controller is controlled. However, since multiple water-cooled controllers are actually connected in series in the same cooling loop, it is impossible to control the temperature corresponding to a certain controller individually, which makes implementation difficult. Alternatively, a heating module is added to heat the controller and the coolant synchronously, which further increases energy consumption. Summary of the invention

DETAILED DESCRIPTION

[0043] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0045] The heat dissipation device, heat dissipation control method, medium and vehicle of the water cooling controller provided in the embodiments of the present disclosure are exemplarily described below in conjunction with the accompanying drawings.

[0046] For example, Figure 1 This is a schematic diagram of the structure of a heat dissipation device of a water-cooled controller provided in an embodiment of the present disclosure. Figure 1 The heat dissipation device of the water-cooled controller includes: a logic control component 160, a proton exchange membrane dehumidifier 120 and a proton exchange component 180; the output end of the logic control component 160 is connected to the input end of the proton exchange membrane dehumidifier 120, and the output end of the proton exchange membrane dehumidifier 120 is connected to the proton exchange component 180; the logic control component 160, the proton exchange membrane dehumidifier 120 and the proton exchange component 180 are all located inside the cavity of the water-cooled controller 110; the logic control component 160 is used to control the proton exchange membrane dehumidifier 120 to apply an electrolysis voltage to the proton exchange component 180 when the cavity of the water-cooled controller 110 reaches a critical condition for condensation; the proton exchange component 180 is used to electrolyze water vapor molecules in the cavity of the water-cooled controller 110 based on the electrolysis voltage to generate gas.

[0047] Among them, the water-cooled controller 110 is a controller that introduces a water-cooled heat dissipation method. It should be noted that when the controller needs to integrate more functions, the functional requirements of the main control chip and the system-on-a-Chip (SoC) on the corresponding printed circuit board (PCB) are increasing, and the more complex the function and the higher the computing power of the chip, the greater the thermal power consumption required. For this reason, in the heat dissipation design, the relevant controller will introduce a water-cooled heat dissipation method to solve the heat generation problem of the above high-power (or high-power consumption) chips during work.

[0048] It is not difficult to understand that the logic control component 160 is used to determine whether the cavity of the water cooling controller 110 has reached the critical condition of condensation and to control the state of the proton exchange membrane dehumidifier 120 .

[0049] Among them, the critical condensation condition is a condition used to measure whether the water-cooled controller 110 can form condensation. When the critical condensation condition is reached, specifically: when the coolant temperature is less than or equal to the dew point temperature corresponding to the current ambient temperature, condensation can be formed. For example, when the cavity of the water-cooled controller 110 reaches the critical condensation condition, the logic control component 160 controls the proton exchange membrane dehumidifier 120 to apply an electrolysis voltage to both ends of the proton exchange component 180. Then, under the action of the electrolysis voltage, the proton exchange component 180 will electrolyze the water vapor molecules in the cavity of the water-cooled controller 110 to generate gas. In this way, by converting water vapor molecules into gas, the air humidity in the cavity of the water-cooled controller 110 is significantly reduced, thereby further destroying the critical condensation condition in the cavity of the water-cooled controller 110.

[0050] When the critical condition of condensation is reached, that is, the coolant temperature is less than or equal to the dew point temperature corresponding to the current ambient temperature, condensation forms in the cavity of the water-cooled controller 110; correspondingly, when the critical condition of condensation is not reached, that is, the coolant temperature is greater than the dew point temperature corresponding to the current ambient temperature, condensation does not form in the cavity of the water-cooled controller 110. Here, the coolant temperature is equivalent to the cavity temperature of the water-cooled controller 110, and the specific method of obtaining the coolant temperature, ambient temperature and dew point temperature is exemplified in the following text.

[0051] It should be noted that in the actual vehicle control process, a preset number of water-cooling controllers 110 are connected in series in the same cooling loop filled with coolant, resulting in the coolant temperature being the temperature generated by the combined action of all the water-cooling controllers 110. Therefore, the coolant temperature in the cooling loop and a single water-cooling controller 110 cannot correspond one-to-one. For this reason, compared with the method in the related art of adjusting the temperature difference between the coolant temperature and the ambient temperature in the water cooling system to avoid the formation of condensation, the method of electrolyzing the water vapor molecules in the water-cooling controller 110 in the embodiment of the present disclosure is more practical.

[0052] Here, the specific position and structural form of the proton exchange membrane dehumidifier 120 and the proton exchange assembly 180 inside the cavity of the water-cooled controller 110 are not limited. Since the structural form of the two does not depend on the specific structure inside the cavity of the water-cooled controller 110, for example, a heat dissipation boss in contact with the printed circuit board is provided in the water-cooled controller 110 for chip heat dissipation, so the proton exchange membrane dehumidifier 120 and the proton exchange assembly 180 can be installed at any position in the cavity and have any structure. It is only necessary to ensure that a good dehumidification effect can be achieved in the water-cooled controller 110. For example: with respect to the installation position, the proton exchange membrane dehumidifier 120 and the proton exchange assembly 180 can be installed at the bottom, top or other positions inside the cavity of the water-cooled controller 110. With respect to the structural form, the proton exchange membrane dehumidifier 120 and the proton exchange assembly 180 can be a cube, a column or other structural forms; specifically, Figure 2 A schematic diagram of the orientation structure of a proton exchange membrane dehumidifier and a proton exchange assembly provided in an embodiment of the present disclosure, wherein the proton exchange membrane dehumidifier 120 and the proton exchange assembly 180 having a cubic structure are both located at the bottom end of the cavity of the water-cooled controller 110; Figure 3 Another schematic diagram of the orientation structure of a proton exchange membrane dehumidifier and a proton exchange assembly is provided for an embodiment of the present disclosure, wherein the proton exchange membrane dehumidifier 120 and the proton exchange assembly 180 having a cubic structure are both located at the top of the interior of the water-cooled controller 110 cavity; thereby, the technical problems of the related art of adding a heating module to the water-cooled controller, such as the complex structure and the difficulty in large-scale stable supply, are solved, thereby improving the practicability of the device.

[0053] The heat dissipation device of the water-cooled controller provided in the embodiment of the present disclosure includes: a logic control component 160, a proton exchange membrane dehumidifier 120 and a proton exchange component 180; the logic control component 160, the proton exchange membrane dehumidifier 120 and the proton exchange component 180 are all located inside the cavity of the water-cooled controller 110; the logic control component 160 is used to control the proton exchange membrane dehumidifier 120 to apply an electrolysis voltage to the proton exchange component 180 when the cavity of the water-cooled controller 110 reaches a critical condition for condensation; the proton exchange component 180 is used to electrolyze water vapor molecules in the cavity of the water-cooled controller 110 based on the electrolysis voltage to generate gas. In this way, in order to reach the critical condition of condensation, an electrolysis voltage is applied to the proton exchange component 180 through the proton exchange membrane dehumidifier 120 to carry out an electrolysis reaction of water vapor molecules, thereby reducing the water vapor molecule content in the cavity, further destroying the critical condition of condensation, preventing the water cooling controller 110 from forming condensation, and improving the practicality of the device. It only needs to convert water vapor molecules into gas, and the electrolysis reaction formed is simple, which is conducive to reducing energy consumption.

[0054] In some embodiments, Figure 4A schematic diagram of the structure of another heat dissipation device of a water-cooled controller provided in an embodiment of the present disclosure. Figure 1 Based on Figure 4 The proton exchange assembly 180 includes a proton exchange membrane 130, a positive electrode plate 140 and a negative electrode plate 150; the positive electrode plate 140 and the negative electrode plate 150 are located on opposite sides of the proton exchange membrane 130; the proton exchange membrane 130 is used to transfer and ionize protons according to the potential at the positive electrode plate 140 and the negative electrode plate 150; the positive electrode plate 140 is used to generate oxygen based on the transfer and ionization of protons at the proton exchange membrane 130; the negative electrode plate 150 is used to generate hydrogen based on the transfer and ionization of protons at the proton exchange membrane 130.

[0055] in, Figure 4 Also shown in FIG. 1 is a water vapor molecule 01 located at the proton exchange membrane 130, which can be represented by the chemical formula H2O. Specifically, Figure 4 Taking the orientation and structure shown as an example, the positive plate 140 is located below the proton exchange membrane 130, and the negative plate 150 is located above the proton exchange membrane 130. The proton exchange membrane dehumidifier 120 is connected to the proton exchange membrane 130 through the positive plate 140 and the negative plate 150. Based on this, when the critical condition of condensation is reached, the proton exchange membrane dehumidifier 120 applies electrolysis voltage to the positive plate 140 and the negative plate 150 respectively, and the water vapor molecules 01 (H2O) at the proton exchange membrane 130 are transferred and ionized under the action of the electrolysis voltage. After that, 2H2O-4e - =4H + +O2 reaction, that is, oxygen is produced at the positive plate 140; correspondingly, 4H + +4e - =2H2 reaction, that is, hydrogen is produced at the negative electrode plate 150.

[0056] In some embodiments, reference Figure 4 , the potential of the positive plate 140 and the negative plate 150 is at least 1.5V.

[0057] Combined with the proton transfer and ionization process mentioned above, it can be seen that the electrolysis reaction of water vapor molecules is relatively simple. In view of this, the electrolysis voltage applied by the proton exchange membrane dehumidifier 120 to the positive plate 140 and the negative plate 150 is relatively small, that is, only a small electrolysis voltage is needed to form an ionized environment at the proton exchange membrane, thereby realizing the electrolysis reaction of water vapor molecules, which is beneficial to reducing the energy consumption of the heat dissipation device of the water-cooled controller.

[0058] Exemplarily, the potentials of the positive plate 140 and the negative plate 150 can both be 1.5V, 2V, 2.5V or other potentials or potential ranges to achieve the electrolysis voltage required for the electrolysis reaction of water vapor molecules. It can be set according to the energy consumption requirements of the heat dissipation device of the water cooling controller and is not limited here.

[0059] In some embodiments, reference Figure 1 The heat dissipation device of the water-cooled controller also includes: an ambient temperature and humidity sensor and a coolant temperature sensor (not shown in the figure); the ambient temperature and humidity sensor and the coolant temperature sensor are both connected to the input end of the logic control component 160; the ambient temperature and humidity sensor and the coolant temperature sensor are located inside the cavity of the water-cooled controller 110; the ambient temperature and humidity sensor is used to collect ambient temperature and ambient humidity; the coolant temperature sensor is used to collect coolant temperature.

[0060] Specifically, after the ambient temperature and humidity sensor collects the temperature and humidity of the environment in which the water-cooled controller 110 is located, and the coolant temperature sensor collects the coolant temperature, the corresponding dew point temperature can be obtained for the ambient temperature and ambient humidity, and the coolant temperature and the dew point temperature can be further compared and judged to determine whether the cavity of the water-cooled controller 110 has reached the critical condition for condensation at this time, so as to control whether the proton exchange membrane dehumidifier 120 is started. The specific process of obtaining the dew point temperature is exemplified in the following text.

[0061] It should be noted that the heat dissipation device of the water-cooled controller provided in the embodiment of the present disclosure can collect the ambient temperature, ambient humidity and coolant temperature in real time, so as to make a real-time judgment on whether the cavity of the water-cooled controller 110 has reached the critical condition of condensation, and timely control the state of the proton exchange membrane dehumidifier 120 (including startup and shutdown), so as to effectively avoid the formation of condensation in the cavity of the water-cooled controller 110.

[0062] Exemplarily, the ambient temperature and humidity sensor and the coolant temperature sensor can be installed on the top, side wall, bottom or other positions of the water-cooled controller 110. Specifically, the ambient temperature and humidity sensor can be installed on the top of the water-cooled controller 110, and the coolant temperature sensor can be installed on the side wall of the water-cooled controller 110. Alternatively, the ambient temperature and humidity sensor can be installed on the bottom of the water-cooled controller 110, and the coolant temperature sensor can be installed on the top of the water-cooled controller 110. Alternatively, both the ambient temperature and humidity sensor and the coolant temperature sensor can be installed on the side wall of the water-cooled controller 110. The specific positions of the ambient temperature and humidity sensor and the coolant temperature sensor inside the cavity of the water-cooled controller 110 are not limited herein.

[0063] In some embodiments, Figure 5 This is a schematic diagram of the structure of another heat dissipation device of a water-cooled controller provided in an embodiment of the present disclosure. Figure 5The logic control component 160 also includes a logic calculation unit (not shown in the figure); the proton exchange membrane dehumidifier 120, the ambient temperature and humidity sensor, and the coolant temperature sensor are all communicatively connected to the logic calculation unit; the logic calculation unit is used to determine whether the critical condition of condensation is reached based on the ambient temperature, ambient humidity and coolant temperature, and control the start-up of the proton exchange membrane dehumidifier 120 in response to the critical condition of condensation being reached.

[0064] Specifically, the logic calculation unit receives the data of ambient temperature and ambient humidity collected by the corresponding sensors, and then obtains the corresponding dew point temperature based on the ambient temperature and ambient humidity. Thereafter, the obtained dew point temperature and coolant temperature can be compared through the logic comparator (not shown in the figure) in the logic control component 160 to determine whether the cavity of the water-cooled controller 110 has reached the critical condition of condensation. Based on this, the proton exchange membrane dehumidifier 120 is controlled to start or not.

[0065] Specifically, the above corresponding sensors (ambient temperature and humidity sensors and coolant temperature sensors) can communicate with the logic control component 160 by wireless transmission. For example, the data corresponding to the ambient temperature and ambient humidity collected by the ambient temperature and humidity sensors, and the data corresponding to the coolant temperature collected by the coolant temperature sensor can be sent to the logic control component 160; the proton exchange membrane dehumidifier 120 and the logic control component 160 can communicate with each other by wired transmission. For example, the logic calculation unit in the logic control component 160 can choose whether to send a start-up instruction to the proton exchange membrane dehumidifier 120 based on the comparison result of the dew point temperature and the coolant temperature.

[0066] In some embodiments, continue to refer to Figure 5 The heat dissipation device of the water-cooled controller also includes a waterproof breathable valve 170; the waterproof breathable valve 170 is located on the surface of the water-cooled controller 110; the waterproof breathable valve 170 is used for air exchange and to prevent external water vapor molecules from entering the cavity of the water-cooled controller 110.

[0067] It should be noted that the water-cooled controller 110 provided in the embodiment of the present disclosure is a sealed domain controller. In order to balance the internal and external pressure difference, a waterproof breathable valve 170 is provided on the water-cooled controller 110. On the one hand, it can prevent external liquid water vapor molecules from entering the water-cooled controller 110, playing a waterproof role; on the other hand, it can allow the gas to circulate normally, thereby ensuring that the air pressure inside and outside the water-cooled controller 110 is consistent, playing a role of ventilation and stabilizing the air pressure. However, it is not difficult to understand that although the water-cooled controller 110 is a watertight device, it also has a breathable effect, and some gas molecules can still enter the water-cooled controller 110, so that the humidity inside the water-cooled controller 110 is affected by the outside world, which is easy to form condensation.

[0068] On the basis of the above implementations, the embodiments of the present disclosure further provide a heat dissipation control method for a water-cooled controller, which is implemented by applying any of the above heat dissipation devices of the water-cooled controller and has corresponding beneficial effects.

[0069] In some embodiments, Figure 6 A schematic diagram of a heat dissipation control method of a water cooling controller provided in an embodiment of the present disclosure. The heat dissipation control method can be executed by a logic control component in a heat dissipation device of the water cooling controller. Figure 6 , the heat dissipation control method may include the following steps:

[0070] S210: Collect ambient temperature, ambient humidity and coolant temperature.

[0071] Specifically, the logic control component can control the ambient temperature and humidity sensors and the coolant temperature sensor to collect corresponding data in real time, and receive the data corresponding to the ambient temperature, ambient humidity and coolant temperature collected by the ambient temperature and humidity sensors and the coolant temperature sensor, so as to facilitate the subsequent judgment of whether the critical conditions for condensation are reached.

[0072] S220: Substitute the collected ambient temperature and ambient humidity into the correlation relationship to determine the dew point temperature corresponding to the current ambient temperature.

[0073] The correlation relationship is the correlation relationship between the dew point temperature and the ambient temperature and the ambient humidity. Specifically, after receiving the data corresponding to the ambient temperature and the ambient humidity, the logic control component substitutes the data corresponding to the ambient temperature and the ambient humidity into the correlation relationship so that the data corresponding to the ambient temperature and the ambient humidity correspond to the dew point temperature, thereby determining the dew point temperature corresponding to the current ambient temperature.

[0074] Among them, the association relationship can be an association formula or an association table, and the parameters included in the association formula or the association table include ambient temperature, ambient humidity and dew point temperature, so as to obtain the required dew point temperature through the known ambient temperature and ambient humidity. In other embodiments, it can also be other forms of association relationships known to technical personnel in this field, which are not limited here.

[0075] For example, the correlation formula may be a dew point temperature calculation (Magnus-Tetens) formula:

[0076]

[0077] Wherein, a and b are constants: a=17.27, b=237.7, T represents the ambient temperature, and Rh represents the ambient humidity.

[0078] Exemplarily, the association relationship can also be an association table. Table 1 is an ambient temperature, ambient humidity, and dew point temperature comparison table provided by an embodiment of the present disclosure. As shown in Table 1, different ambient temperatures (represented by T), ambient humidity (represented by Rh), and dew point temperatures (represented by Td) are shown in the table, wherein the units corresponding to the ambient temperature and the dew point temperature are both degrees Celsius (°C), and the ambient humidity is unitless and is expressed in a proportional form (%). Specifically, after determining a certain ambient temperature and a certain ambient humidity, the corresponding dew point temperature can be determined based on the overlap of rows and columns; for example, when the ambient temperature is 13°C and the ambient humidity is 80%, it can be determined that the dew point temperature at this time is 9.6°C. The specific values ​​of the ambient temperature, ambient humidity, and dew point temperature are not limited here.

[0079] Table 1 Comparison table of ambient temperature, ambient humidity and dew point temperature

[0080]

[0081]

[0082] Specifically, the collected data corresponding to the current ambient temperature and ambient humidity are substituted into the above dew point temperature calculation formula. Since a and b are known constants, the corresponding dew point temperature is directly calculated through the logic control component; or, the collected data corresponding to the current ambient temperature and ambient humidity are substituted into the ambient temperature, ambient humidity, and dew point temperature comparison table. If the same ambient temperature and ambient humidity are matched in Table 1, the corresponding dew point temperature can be directly obtained according to the overlap of rows and columns. If the same ambient temperature and ambient humidity are not matched, the difference calculation can be performed according to the similar ambient temperature and ambient humidity, and the corresponding dew point temperature can also be obtained. The specific process of the difference calculation will not be repeated here.

[0083] It should be noted that although the dew point temperatures obtained by the above two methods may have certain errors, in the actual calculation process, a preset software tolerance coefficient can be set through the logic control component to ensure that the critical conditions for condensation are effectively destroyed. The specific size of the software tolerance coefficient is not limited here.

[0084] S230: When the cavity of the water-cooled controller reaches a critical condensation condition, control the proton exchange membrane dehumidifier to apply an electrolysis voltage to the proton exchange component.

[0085] Specifically, when the cavity of the water-cooled controller reaches the critical condition of condensation, the logic control component sends a start-up instruction to the proton exchange membrane dehumidifier to control the start-up of the proton exchange membrane dehumidifier, and then controls the proton exchange membrane dehumidifier to apply an electrolysis voltage to both ends of the proton exchange membrane to realize the electrolysis reaction of water vapor molecules at the proton exchange membrane.

[0086] S240, based on the electrolysis voltage, electrolyze the water vapor molecules in the cavity of the water cooling controller to generate gas.

[0087] Specifically, in combination with the above steps, under the action of the electrolysis voltage at both ends of the proton exchange membrane, reactions to produce oxygen and hydrogen occur at the positive plate and the negative plate respectively. Since the water vapor molecules in the cavity of the water-cooled controller are continuously ionized and converted into gas, the air humidity in the cavity of the water-cooled controller 110 is significantly reduced, which will not be repeated here.

[0088] It should be noted that the logic control component can determine whether the cavity of the water-cooled controller has reached the critical condition for condensation by comparing the coolant temperature with the dew point temperature corresponding to the current ambient temperature, so as to choose whether to send a start-up instruction to the proton exchange membrane dehumidifier 120. Specifically, if the coolant temperature is greater than the dew point temperature corresponding to the current ambient temperature, it indicates that the critical condition for condensation has not been reached at this time, and condensation will not form, and the logic control component will not send a start-up instruction to the proton exchange membrane dehumidifier 120; otherwise, it indicates that the critical condition for condensation has been reached at this time, and there is a risk of condensation forming, and the logic control component sends a start-up instruction to the proton exchange membrane dehumidifier 120. This can be understood in conjunction with the working process of the logic control component above, and will not be repeated here.

[0089] In some embodiments, in combination Figure 6 After the dew point temperature corresponding to the current ambient temperature is determined in S220, the following steps are also included:

[0090] Step 1: Compare the dew point temperature and the coolant temperature and obtain a comparison result.

[0091] Specifically, the logic control component compares the obtained dew point temperature with the received coolant temperature to determine whether the critical condition of condensation is reached, and performs subsequent corresponding operations based on the comparison result (or judgment result).

[0092] Step 2: Determine that the comparison result reaches the critical condition of condensation, and control the proton exchange membrane dehumidifier to start.

[0093] Combined with step one, the subsequent corresponding operations include: when it is determined that the critical condition for condensation is reached, controlling the proton exchange membrane dehumidifier to start, and when it is determined that the critical condition for condensation is not reached, not starting the proton exchange membrane dehumidifier. The working process after the proton exchange membrane dehumidifier is started will not be described here.

[0094] For example, Figure 7 A schematic diagram of a flow chart of another heat dissipation control method of a water cooling controller provided in an embodiment of the present disclosure. Based on the above steps, refer to Figure 7 , the water cooling heat dissipation control method comprises:

[0095] S310: Obtain ambient temperature T and ambient humidity Rh.

[0096] Among them, the logic control component can first obtain the ambient temperature (represented by T) and ambient humidity (represented by Rh) collected by the ambient temperature and humidity sensor, so as to further obtain the dew point temperature corresponding to the two.

[0097] S320: Obtain the dew point temperature Td.

[0098] Among them, the logic control component can obtain the dew point temperature Td based on the correlation between the ambient temperature T and the ambient humidity Rh. The specific form of the correlation will be explained later.

[0099] S330, obtaining the coolant temperature T1.

[0100] For example, after determining the dew point temperature Td, the logic control component may obtain the coolant temperature (denoted by T1) to facilitate subsequent determination of whether the critical condensation condition is reached.

[0101] S340, T1≤Td?

[0102] Specifically, the coolant temperature T1 is compared with the dew point temperature Td to determine whether the coolant temperature T1 is less than or equal to the dew point temperature Td corresponding to the current ambient temperature; if so, execute S360; if not, execute S350.

[0103] S350, end.

[0104] Exemplarily, when the coolant temperature T1 is greater than the dew point temperature Td, the logic control component does not start the proton exchange membrane dehumidifier, and directly ends the current control process of the proton exchange membrane dehumidifier.

[0105] S360, start the proton exchange membrane dehumidifier.

[0106] Exemplarily, when the coolant temperature T1 is less than or equal to the dew point temperature Td, the logic control component starts the proton exchange membrane dehumidifier to make the proton exchange membrane dehumidifier start working, such as using the proton exchange membrane ionization method to ionize water vapor molecules and convert them into oxygen and hydrogen to reduce the content of water vapor molecules in the water-cooled controller cavity.

[0107] In some embodiments, the heat dissipation control method of the water cooling controller further includes: starting the proton exchange membrane dehumidifier, determining that the critical condition for condensation has not been reached, and controlling the proton exchange membrane dehumidifier to shut down.

[0108] Specifically, since the ambient temperature and humidity sensor collects the ambient temperature and humidity in real time, and the coolant temperature sensor collects the coolant temperature in real time, the logic control component will still determine in real time whether the water-cooled controller has reached the critical condition for condensation. When the proton exchange membrane dehumidifier is started, affected by the speed of the electrolysis reaction, the critical condition for condensation may still be met within the preset time. Therefore, the electrolysis reaction of water vapor molecules can continue at the proton exchange membrane during the period when the critical condition for condensation is reached. When the air humidity in the cavity of the water-cooled controller 110 drops significantly to the point where the logic control component determines that the critical condition for condensation has not been reached, the proton exchange membrane dehumidifier is controlled to be shut down so that the electrolysis reaction of water vapor molecules no longer occurs at the proton exchange membrane.

[0109] It should be noted that, in combination with the above dew point temperature calculation formula, it can be seen that since the electrolysis reaction of water vapor molecules at the proton exchange membrane will produce gas, the content of water vapor molecules in the water-cooled controller cavity is reduced. Correspondingly, the air humidity in the water-cooled controller 110 cavity is significantly reduced. When the ambient temperature remains unchanged, the ambient humidity decreases, which will cause the corresponding dew point temperature to decrease, thereby destroying the critical conditions for condensation and effectively reducing the risk of condensation forming in the water-cooled controller cavity.

[0110] It can be seen that for electronic products, if condensation (condensed water) is formed inside the electronic products, it will not only cause circuit short circuits and lead to major quality problems such as fire, but also increase the humidity inside the electronic products, which will have a greater impact on the life of components in the electronic products. Compared with the temperature control methods that are difficult to achieve in related technologies and the heating methods that consume more thermal power, for example: adding heating components such as resistance wires to the inner cavity of the entire water-cooled controller for forming condensation, and synchronously heating the cavity and the internal coolant through the heating components to prevent condensation from forming in the water-cooled controller. The water-cooled heat dissipation control method provided in the embodiment of the present disclosure can reduce the air humidity in the water-cooled controller by consuming lower power consumption, thereby achieving efficient and quick destruction of the critical conditions of condensation, avoiding functional failure of the water-cooled controller due to the formation of condensation, and has high cost performance and feasibility.

[0111] Based on this, the heat dissipation control method of the water cooling controller provided in the embodiment of the present disclosure can also be applied to the internal humidity control of electronic products. By controlling the internal components of the electronic products, it is ensured that there is a lower air humidity inside the electronic products, thereby avoiding aging and failure of the internal components of the electronic products in a high temperature and high humidity environment, enhancing the long-term durability and reliability of the electronic products, and further improving and extending the service life of the electronic products.

[0112] The embodiment of the present disclosure also provides a computer-readable storage medium, which stores a program or instruction, and the program or instruction enables a computer to execute the steps of any of the above heat dissipation control methods of a water cooling controller.

[0113] An embodiment of the present disclosure also provides a vehicle, comprising a heat dissipation device of any one of the water-cooling controllers provided in the above embodiments.
