The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0035] Reference Figure 1 , Figure 1 A structural diagram of the anti-condensation system of the domain controller provided in an embodiment of the present application. In some embodiments of one aspect of the present application, the anti-condensation system of the domain controller includes: a control board 100, a liquid cooling shell, multiple heating modules 300 and multiple condensation detection modules.

[0036] The liquid cooling housing has an accommodating cavity 200 therein for accommodating the control board 100 and fixing the control board 100. Cooling liquid flows through the liquid cooling housing and can transfer heat generated by the control board 100.

[0037] Several heating elements 110 are soldered to the control board 100. Based on the amount of heat generated by the heating elements 110 during operation and the density of their arrangement, the control board 100 is divided into multiple heating zones. The area of ​​a heating zone is inversely correlated with the amount of heat generated, and the area of ​​a heating zone is also inversely correlated with the density of the heating elements 110 within the zone.

[0038] In other words, the control board 100 is divided into a certain number of heating areas based on the presence of heating devices 110. When dividing the heating areas, the higher the density of heating devices 110 in the heating area, the greater the total heat generated within the heating area, and the smaller the area of ​​the heating area on the control board 100. Otherwise, the lower the density of heating devices 110 in the heating area, the smaller the total heat generated within the heating area, and the larger the area of ​​the heating area on the control board 100.

[0039] A condensation detection module is provided on each heating area. One condensation detection module is located in one heating area. The heating areas correspond to the condensation detection modules one by one. Multiple heating areas correspond to multiple condensation detection modules. Multiple condensation detection modules are all welded on the control board 100. The condensation detection modules can monitor the relative humidity in the corresponding heating areas in real time.

[0040] In other words, the number and soldering locations of the condensation detection modules are determined based on the density and heat output of the heating elements 110 on the control board 100, and the zoning configuration is performed. The number of heating zones matches the number of condensation detection modules, and the soldering locations of the condensation detection modules are affected by the heat output of the heating zones.

[0041] In one embodiment, in a heating area, the heat distribution in the heating area is detected, and based on the heat distribution, the center point of the heat distribution, that is, the point where the heat generation is most concentrated, is determined, and the center point is used as the welding position for installing the condensation detection module in the current heating area.

[0042] The condensation detection module may be an HDP-07 condensation detection module or an NHJL12X condensation detection module. In this embodiment, no specific limitation is imposed on the type of the condensation detection module.

[0043] A heating module 300 is provided corresponding to each heating area, and the heating area corresponds to the heating module 300 one by one. Multiple heating areas correspond to multiple heating modules 300, and multiple heating modules 300 are all installed on the inner wall of the liquid cooling shell. The heating module 300 can heat the liquid cooling shell and reduce the relative humidity of the corresponding heating area in the accommodating cavity 200 of the liquid cooling shell, so that it cannot condense into water droplets, thereby avoiding the risk of condensation.

[0044] In other words, the number and shape of the heating modules 300 are determined based on the heating zones on the control board 100. The number of heating zones matches the number of heating modules 300, and the shapes of the heating modules 300 correspond to the shapes within the heating zones, enabling zoned heating. Multiple heating zones can be connected in parallel, enabling activation based on the desired anti-condensation strategy.

[0045] In one embodiment, the heating power of the heating module 300 is positively correlated with the heat output of the heating area and the density of the heating devices 110 in the heating area. That is, the heating power of the heating module is adapted based on the density and heat output of the heating devices 110 in the heating area. The higher the density of the heating devices 110 in the heating area, the greater the sum of the heat output within the heating area, and the higher the heating power of the heating module 300 used in the corresponding heating area on the condenser housing. Otherwise, the lower the density of the heating devices 110 in the heating area, the smaller the sum of the heat output within the heating area, and the lower the heating power of the heating module 300 used in the corresponding heating area on the condenser housing.

[0046] The heating module 300 may be an electric heating plate or an infrared heating plate. In this embodiment, there is no specific limitation on the type of the heating module 300.

[0047] In one embodiment, the current relative humidity detected by the condensation detection module is obtained to determine the condensation status of the current heating area. The relative humidity is then compared with a threshold value for analysis. Based on the different comparison results, different condensation risk levels are determined, thereby determining different anti-condensation strategies. Based on the corresponding anti-condensation strategy, a corresponding drive signal is output to the corresponding heating module 300, driving the heating module 300 corresponding to the current heating area, or also driving adjacent heating modules 300 to operate, thereby achieving on-demand zoned activation, effectively improving energy efficiency and saving electricity. The drive signal may include: heating operation duration and heating operation power.

[0048] Exemplarily, the relative humidity detected by the current condensation detection module is obtained to determine the condensation situation of the current heating area. If the relative humidity of the current heating area is greater than the set first condensation threshold and less than the set second condensation threshold, it is considered that there is a condensation risk in the current heating area, and the condensation risk level of the current heating area is recorded as the first-level condensation risk. The anti-condensation strategy corresponding to the first-level condensation risk is determined, and a drive signal is output to the heating module 300 corresponding to the current heating area to achieve precise monitoring and start heating in different zones as needed.

[0049] Exemplarily, the relative humidity detected by the current condensation detection module is obtained to determine the condensation situation of the current heating area. If the relative humidity of the current heating area is greater than the set second condensation threshold, it is considered that the condensation risk of the current heating area is increased, and the condensation risk level of the current heating area is recorded as the second-level condensation risk. The anti-condensation strategy corresponding to the second-level condensation risk is determined, and a drive signal is output to the heating module 300 corresponding to the current heating area, and a drive signal is output to the heating module 300 adjacent to the heating module 300 corresponding to the current heating area, so as to improve the heating efficiency and enhance the energy utilization efficiency.

[0050] Through the above-mentioned embodiment, the condensation detection module replaces the traditional combination of temperature sensor and humidity sensor to monitor the relative humidity of the air in the internal storage chamber 200 of the domain controller in real time. The traditional monitoring strategy is to obtain the temperature and humidity of the storage chamber 200 of the liquid-cooled shell through the temperature sensor and humidity sensor respectively, and then use the built-in enthalpy-humidity diagram curve to analyze the condensation temperature in the current environment, and then start the heating device. The condensation detection module of the present application can directly obtain the relative humidity of the storage chamber 200, compare and analyze the relative humidity with the threshold, determine the corresponding anti-condensation strategy, and start the corresponding heating module 300, thereby greatly simplifying the monitoring strategy and improving monitoring efficiency.

[0051] In existing sensor monitoring methods, most use one or a group of sensors to monitor the humidity inside the entire domain controller, and there is only one heating device, making it difficult to achieve accurate monitoring. This application adopts a regional monitoring method, dividing the circuit board into different areas according to the layout density of the circuit board heating device 110 and the heat generated by the device. Condensation monitoring is performed separately in different areas, and the corresponding heating device is also configured in corresponding zones on the surface of the corresponding liquid cooling shell. This can significantly improve the monitoring response accuracy. At the same time, the heating device is activated in different zones according to demand, which can effectively improve energy utilization efficiency and save electricity.

[0052] The present application can identify risks in advance before condensation occurs by setting a monitoring threshold of the condensation sensor, and start the heating module 300 to avoid the occurrence of condensation, thereby achieving the purpose of preventive monitoring.

[0053] Reference Figure 1 In some embodiments of one aspect of the present application, the liquid cooling housing includes: an upper housing 210 , a liquid cooling shell 230 , a lower housing 240 and a heat dissipation portion 220 .

[0054] The upper housing 210 is connected to one end of the liquid-cooled housing 230, and the lower housing 240 is connected to the other end of the liquid-cooled housing 230. The upper housing 210, the liquid-cooled housing 230, and the lower housing 240 form a receiving chamber 200. Coolant flows through the liquid-cooled housing to transfer heat generated by the control board 100.

[0055] The upper shell 210 and the lower shell 240 can be connected to the liquid cooling housing 230 by screw fastening, or by other methods. In this embodiment, no specific limitation is imposed on the connection method of the shells.

[0056] The plurality of heating modules 300 are mounted on the inner wall of the upper housing 210 , corresponding to the plurality of heating areas on the control board 100 , so as to heat the liquid-cooled housing corresponding to the heating areas requiring dehumidification.

[0057] Among them, multiple heating modules 300 can be fixed on the inner wall of the upper shell 210 by gluing to correspond to multiple heating areas on the control board 100 to heat the liquid cooling shell corresponding to the heating areas that need to be dehumidified.

[0058] One end of the heat dissipation portion 220 is connected to the inner wall of the upper housing 210, and the other end of the heat dissipation portion 220 extends toward the control board 100, passes through the corresponding heating module 300, and connects to the heating device 110 in the corresponding heating area on the control board 100. The other end of the heat dissipation portion 220 is filled with a thermally conductive material, thereby forming a thermal conductor, which transfers heat generated by the heating device 110 during operation through the thermally conductive material.

[0059] The thermally conductive material may be thermally conductive silicone grease or thermally conductive silicone sheet. In this application, no specific limitation is imposed on the thermally conductive material forming the thermally conductive component.

[0060] In one embodiment, the current relative humidity detected by the condensation detection module is obtained to determine the current condensation situation in the heating area. The relative humidity is then compared with a threshold value for analysis. Based on the different comparison results, different condensation risk levels are determined, thereby determining different condensation prevention strategies. When the condensation risk level is no condensation risk, the heat generated by the heating element 110 during operation is transferred through the thermally conductive material on the heat dissipation portion 220, and the heat generated by the control board 100 is transferred through the coolant in the liquid cooling housing.

[0061] Reference Figure 1In some embodiments of one aspect of the present application, in the heating module 300, a gap is set around the corresponding heat dissipation part 220 so that the heat dissipation part 220 can pass through the heating module 300 through the gap, connect with the heating device 110, and fix the heat dissipation part 220.

[0062] That is, an avoidance gap is reserved at the heat dissipation portion 220 corresponding to each heating module 300 to fix the heat dissipation portion 220 and facilitate the heat dissipation portion 220 to pass through.

[0063] The heat dissipation portion 220 may be a heat dissipation boss or a heat dissipation column, and the specific shape of the heat dissipation portion 220 is not limited in this application.

[0064] Figure 2 This is an optional flowchart of the domain controller anti-condensation method provided in an embodiment of the present application. In some embodiments of another aspect of the present application, the domain controller anti-condensation method may include but is not limited to steps S100 to S300.

[0065] Step S100 , detecting the heat generated by the control board during operation, and determining the density of the heat generating components on the control board according to the heat generated.

[0066] In step S200, a plurality of heating areas are divided on the control board according to the heat generation and the density of the heating devices, and the heating modules required for the corresponding heating areas are determined, wherein the area of ​​the heating area is inversely correlated with the heat generation of the heating area and the density of the heating devices in the heating area.

[0067] Step S300: Obtain the relative humidity detected by the condensation detection module in the current heating area, determine the condensation risk level based on the relative humidity, and operate the corresponding heating module based on the condensation risk level to reduce the relative humidity.

[0068] In steps S100 to S300 shown in the embodiment of the present application, the control board is divided into different heating areas for monitoring by the arrangement density of the heating devices on the control board and the heating value of the heating devices, and heating prevention is performed separately for different heating areas, rather than the traditional overall monitoring and overall heating prevention, thereby improving the monitoring accuracy and energy utilization efficiency; and according to the heating value and density, the welding positions of the heating module and the condensation detection module required for the heating area are determined, and the anti-condensation strategy and the monitoring strategy are run for each heating area in a targeted manner, and the anti-condensation strategy and the monitoring strategy are executed in partitions to start the heating module before condensation, realize preventive monitoring, avoid the occurrence of condensation, improve monitoring accuracy, optimize resource allocation and increase system stability.

[0069] In some embodiments of step S100 , the heat generated by the control board during operation is detected, and a heat generating device is selected based on the heat generating device, thereby determining the density of the heat generating devices arranged on the control board.

[0070] In one embodiment, a temperature detector and an infrared detector can be used to scan the operating control panel to obtain heat generation and detect heat-generating components. An image of the control panel is captured, and heat-generating components and their corresponding heat generation values ​​are marked on the image to delineate heat-generating areas.

[0071] In another embodiment, a thermal imaging camera can be used to scan a running control panel to obtain heat-generating components. An image of the control panel is captured, and the heat-generating components and the heat generated by the components are marked on the image to demarcate the heat-generating areas.

[0072] In some embodiments of step S200, a plurality of heating elements are welded to the control board. Based on the heat output and the density of the heating elements, the control board is divided into a plurality of heating regions according to a predetermined partitioning pattern. The area of ​​a heating region is inversely correlated with the heat output of the region, and the area of ​​a heating region is also inversely correlated with the density of the heating elements within the region.

[0073] In other words, the control board is divided into a certain number of heating zones based on the presence of heating devices. When dividing the zones, the higher the density of heating devices in the heating zone, the greater the total heat generated within the zone, and the smaller the area of ​​the heating zone on the control board. Otherwise, the lower the density of heating devices in the heating zone, the smaller the total heat generated within the zone, and the larger the area of ​​the heating zone on the control board.

[0074] The partitioning shape is mainly rectangular. The partitioning shape can also be other types to facilitate the division of areas and adapt to the control panel. The specific shape of the partitioning shape is not limited in this application.

[0075] The heating areas correspond one-to-one to the heating modules, and multiple heating areas correspond to multiple heating modules. The heating modules can heat the liquid-cooled shell, reduce the relative humidity of the corresponding heating areas in the accommodating cavity of the liquid-cooled shell, and prevent them from condensing into water droplets, thereby avoiding the risk of condensation.

[0076] The number and shape of the heating modules are determined based on the heating zones on the control panel. The number of heating zones matches the number of heating modules, and the shapes of the heating modules correspond to the shapes of the heating zones, enabling zoned heating. Multiple heating zones can be connected in parallel to enable activation based on the desired anti-condensation strategy.

[0077] In one embodiment, the heating power of the heating module is positively correlated with the heat output of the heating area and the density of the heating devices in the heating area. That is, the heating power of the heating module is adapted based on the density and heat output of the heating devices in the heating area. The higher the density of the heating devices in the heating area, the greater the sum of the heat output within the heating area, and the higher the heating power of the heating module used in the condenser housing for that heating area. Otherwise, the lower the density of the heating devices in the heating area, the smaller the sum of the heat output within the heating area, and the lower the heating power of the heating module used in the condenser housing for that heating area.

[0078] The heating module may be an electric heating plate or an infrared heating plate. In this embodiment, there is no specific limitation on the type of the heating module.

[0079] In other words, the shape and number of heating modules are determined by the shape and number of the heating areas, and the heating power of the heating modules is determined by the heat output and density of the heating components in the heating areas. Furthermore, the power model of the heating module is positively correlated with the device density and heat output in the corresponding area.

[0080] In some embodiments of step S300, a condensation detection module is provided in each heating area, and the heating areas correspond to the condensation detection modules one by one. Multiple heating areas correspond to multiple condensation detection modules, and the condensation detection modules can monitor the relative humidity in the corresponding heating areas in real time.

[0081] In other words, the number and soldering locations of the condensation detection modules are determined based on the density and heat output of the heating components on the control board, allowing for zoned configuration. The number of heating zones matches the number of condensation detection modules, and the soldering locations of the condensation detection modules are influenced by the heat output of the heating zones.

[0082] In one embodiment, in a heating area, the heat distribution in the heating area is detected, and based on the heat distribution, the center point of the heat distribution, that is, the point where the heat generation is most concentrated, is determined, and the center point is used as the welding position for installing the condensation detection module in the current heating area.

[0083] In some embodiments of another aspect of the present application, in step S200, determining the heating module required for the heating area based on the heat output and the density of the heating device may include but is not limited to step S210:

[0084] In step S210 , the heating power of the heating module is positively correlated with the heat generation of the heating area and the density of the heating components in the heating area.

[0085] In this embodiment, the heating power of the heating module is positively correlated with the heat output of the heating area and the density of the heating devices in the heating area. That is, the heating power of the heating module is adapted based on the density and heat output of the heating devices in the heating area. The higher the density of the heating devices in the heating area, the greater the sum of the heat output within the heating area, and the higher the heating power of the heating module used in the condenser housing for that heating area. Otherwise, the lower the density of the heating devices in the heating area, the smaller the sum of the heat output within the heating area, and the lower the heating power of the heating module used in the condenser housing for that heating area.

[0086] The heating module may be an electric heating plate or an infrared heating plate. In this embodiment, there is no specific limitation on the type of the heating module.

[0087] In other words, the shape and number of heating modules are determined by the shape and number of the heating areas, and the heating power of the heating modules is determined by the heat output and density of the heating components in the heating areas. Furthermore, the power model of the heating module is positively correlated with the device density and heat output in the corresponding area.

[0088] Based on the heat generation of the heating area and the density of the heating devices in the heating area, a power-adaptive heating module is selected to implement an anti-condensation strategy for each heating area in a targeted manner.

[0089] In some embodiments of another aspect of the present application, step S300 may include but is not limited to steps S310 to S312:

[0090] Step S310 , determining whether the relative humidity is greater than a set first condensation threshold and less than a set second condensation threshold.

[0091] Step S311: If yes, it is considered that there is a condensation risk, and the current condensation risk level is determined to be the first level condensation risk.

[0092] Step S312: Based on the first level condensation risk, the heating module corresponding to the current heating area is operated to reduce the relative humidity.

[0093] In this embodiment, the condensation condition of the current heating area is determined by obtaining the relative humidity, and the relative humidity is compared and analyzed with the set first condensation threshold and the set second condensation threshold.

[0094] If the relative humidity of the current heating area is greater than the set first condensation threshold and less than the set second condensation threshold, it is considered that there is a condensation risk in the current heating area, and the condensation risk level of the current heating area is recorded as the first-level condensation risk. The anti-condensation strategy corresponding to the first-level condensation risk is determined, and a driving signal is output to the heating module corresponding to the current heating area to achieve precise monitoring and start heating in zones as needed.

[0095] The first and second condensation thresholds can be set to different values ​​based on actual operating conditions. Alternatively, the monitoring threshold can be set to 90% or 85% to further identify condensation risks in advance and implement preventive monitoring. This application does not impose any restrictions on the specific values ​​of the first and second condensation thresholds.

[0096] In some embodiments of another aspect of the present application, step S300 may include but is not limited to steps S320 to S322:

[0097] Step S320: Determine whether the relative humidity is greater than a set second condensation threshold.

[0098] Step S321: If yes, it is considered that the condensation risk is increased, and the current condensation risk level is determined to be the second level condensation risk.

[0099] Step S322: Based on the second level condensation risk, operate the heating module corresponding to the current heating area, and operate the heating modules adjacent to the current heating module to reduce the relative humidity.

[0100] In this embodiment, the condensation condition of the current heating area is determined by obtaining the relative humidity, and the relative humidity is compared and analyzed with the set first condensation threshold and the set second condensation threshold.

[0101] If the relative humidity of the current heating area is greater than the set second condensation threshold, it is considered that the condensation risk of the current heating area is increased, and the condensation risk level of the current heating area is recorded as the second-level condensation risk. The anti-condensation strategy corresponding to the second-level condensation risk is determined, and a driving signal is output to the heating module corresponding to the current heating area, and a driving signal is output to the heating module adjacent to the heating module corresponding to the current heating area, so as to improve the heating efficiency and enhance the energy utilization efficiency.

[0102] The number of adjacent heating modules to be activated may be determined according to the difference between the relative humidity and the set second condensation threshold.

[0103] Exemplarily, if the relative humidity of the current heating area is greater than the set second condensation threshold, it is considered that the condensation risk of the current heating area is increased, the condensation risk level of the current heating area is recorded as the second-level condensation risk, the anti-condensation strategy corresponding to the second-level condensation risk is determined, and a drive signal is output to the heating module corresponding to the current heating area; according to the difference between the relative humidity and the set second condensation threshold, the number of running heating modules adjacent to the above-mentioned corresponding driven heating module is determined, and when the difference is within the set difference range, the number of adjacent heating modules started is determined to be one, that is, one adjacent heating module is driven, and the heating module corresponding to the current heating area and a heating module adjacent to the heating module corresponding to the current heating area are operated.

[0104] Exemplarily, if the relative humidity of the current heating area is greater than the set second condensation threshold, it is considered that the condensation risk of the current heating area is increased, the condensation risk level of the current heating area is recorded as the second-level condensation risk, the anti-condensation strategy corresponding to the second-level condensation risk is determined, and a drive signal is output to the heating module corresponding to the current heating area; according to the difference between the relative humidity and the set second condensation threshold, the number of running heating modules adjacent to the above-mentioned corresponding driven heating module is determined. When the difference is too large, the number of adjacent heating modules started is determined to be two, that is, two adjacent heating modules are driven, and the heating module corresponding to the current heating area and the two heating modules adjacent to the heating module corresponding to the current heating area are operated.

[0105] In this embodiment, by analogy, the difference can be divided into levels, with the heating module corresponding to the current heating area as the center, spreading outward to the periphery, and pushing the next adjacent heating module to operate, so as to operate two or more heating modules to meet the anti-condensation strategy.

[0106] From S310 to S322, it can be seen that by setting different condensation thresholds, the condensation risk of the current heating area can be determined, so that one or more heating modules can be started according to the condensation risk, and the anti-condensation strategy can be run in a targeted manner. The condensation risk can be further identified in advance to achieve preventive monitoring.

[0107] In some embodiments of another aspect of the present application, the anti-condensation method further comprises:

[0108] S400 , detecting heat distribution of a plurality of heating areas, and determining welding positions of condensation detection modules corresponding to the heating areas according to the heat distribution.

[0109] In one embodiment, in a heating area, the heat distribution in the heating area is detected, and based on the heat distribution, the center point of the heat distribution, that is, the point where the heat generation is most concentrated, is determined, and the center point is used as the welding position for installing the condensation detection module in the current heating area.

[0110] That is to say, the heat distribution of the heating area is detected, and the position where the heat is most concentrated is determined through the heat distribution. This position is used as the welding position, and the condensation detection module is welded to the welding position to enable the condensation detection module to detect the relative humidity of the current heating area.

[0111] In some embodiments of another aspect of the present application, the anti-condensation method further comprises:

[0112] S500: Detect the internal temperature of each heating device in the current heating area and determine whether any internal temperature is greater than a set over-temperature threshold.

[0113] S510: If yes, the running heating module is controlled to stop working.

[0114] In this embodiment, to prevent the heating module from affecting the normal function of the key chip of the domain controller, a temperature monitoring strategy for the heating device is introduced. Each heating device is usually equipped with a temperature detector to monitor the temperature inside the device.

[0115] When the heating module is started, real-time monitoring of the internal temperature of the device is also started. When the internal temperature is lower than the set over-temperature threshold, the heating module continues to heat. When the internal temperature reaches the set over-temperature threshold, all running heating modules stop working.

[0116] Through the above-mentioned real-time monitoring and control strategy of relative humidity and key chip temperature, the domain controller can avoid the risk of condensation while further ensuring the working performance of key chips and ensuring the normal operation of the domain controller.

[0117] The following describes the embodiments of the present invention in detail with reference to specific application examples:

[0118] Reference Figure 3 According to the density of the heating components on the control board and the heat generated during operation, the control board is divided into three heating areas according to the shape of the set rectangle: the first area, the second area and the third area.

[0119] The second region has the largest total heat output and the highest density of heating devices, so it has the smallest area. The first region has the fewest heating devices, the lowest density, and the lowest heat output, so it has the largest area. Condensation detection modules are placed at the locations where heat output is concentrated in each region: the first condensation detection module is placed in the first region, the second condensation detection module is placed in the second region, and the third condensation detection module is placed in the third region.

[0120] Corresponding to the heating area, the number of heating modules is the same as the number of condensation detection modules, including the first heating module, the second heating module, and the third heating module. Among them, based on the second area, the electric heating plate of the second heating module has the smallest area and the highest power consumption; based on the first area, the electric heating plate of the heating module has the largest area and the lowest power consumption. In order to enable the heating modules to be attached to the inner wall of the upper shell, it is necessary to avoid air gaps in the heat dissipation part corresponding to each heating module. The three heating modules are connected in parallel and activated according to the relative humidity of the three heating areas.

[0121] If the second relative humidity detected by the second condensation detection module is greater than the set first condensation threshold and less than the set second condensation threshold, it is identified that there is a risk of condensation in the second area, and the second heating module corresponding to the second area will be activated to achieve precise monitoring.

[0122] If the second relative humidity detected by the second condensation detection module is greater than the set second condensation threshold, it is recognized that the condensation risk in the second area is increased, and the second heating module corresponding to the second area will be activated, and the first heating module and / or the third heating module will be activated to achieve precise monitoring, improve heating efficiency, and save energy.
