Description

Technical Field

[0001] The present application relates to the technical field of new energy vehicles, and particularly to a controller heat dissipation method, system, device, vehicle and equipment. Background Art

[0002] In the controller system of existing new energy vehicles, in order to meet the diverse functional requirements of passengers, more and more different functions are integrated, and the demand for computing power is also increasing. At the same time, high computing power also brings higher power consumption to the controller system, resulting in an increase in the temperature of the controller system.

[0003] Currently, most high-computing-power controller systems use a water-cooling heat dissipation method to dissipate heat from the overheated controller system. However, since most vehicles currently use a series water circulation method for heat dissipation, there will be a situation where the temperature of the water circulation entering the controller in some cases is higher than the temperature of the controller system itself, causing the water circulation to increase the temperature of the controller system, and the heat dissipation effect cannot be guaranteed. Moreover, when the controller system is in a passive heating situation, the service life will be reduced, affecting the use effect. Therefore, a controller heat dissipation system is needed to dissipate heat from the controller as needed to solve the above problems, avoid passive heating, and reduce the life loss of the controller caused by passive heating.

[0046] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0047] In some processes described in the specification, claims and the above-mentioned drawings of the present application, a plurality of operations appear in a specific order. However, it should be clearly understood that these operations may not be executed in the order in which they appear herein or may be executed in parallel. The serial numbers of the operations, such as S101, S102, etc., are only used to distinguish different operations, and the serial numbers themselves do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions such as "first" and "second" in this article are used to distinguish different thresholds, modules, etc., do not represent a sequence, and do not limit that "first" and "second" are of different types.

[0048] The technical solution of the present application is applicable to the water-cooled heat dissipation of the controller system in a vehicle, and can accurately and timely control the water circulation to enter and exit the controller system, avoiding the passive heating of the controller system caused by the too high temperature of the water circulation system, ensuring that the controller system can effectively dissipate heat, achieving the optimal heat dissipation effect, improving the user experience, and prolonging the service life of the controller system.

[0049] In the prior art, a high-computing-power controller system uses a water-cooled heat dissipation method to dissipate heat from the heat-generating controller system. However, since the water circulation method is used for heat dissipation, in some cases, the temperature of the water circulation entering the vehicle-wide water circulation is higher than the temperature of the controller system itself, resulting in the water circulation increasing the temperature of the controller system, and the heat dissipation effect cannot be guaranteed. Moreover, when the controller system is in a state of passive heating, the service life will be reduced, affecting the use effect.

[0050] To solve the above problems, after creative work, the inventor proposed the technical solution of this application, providing a controller heat dissipation control method, which is applied to a controller system, including obtaining temperature information of multiple preset components of a vehicle head unit, where the temperature information includes real-time temperature values of at least one preset component collected by at least one temperature sensor; comparing the temperature information with a first preset threshold, if any real-time temperature value in the temperature information is greater than or equal to the first preset threshold, controlling the working state of the water circulation switch to be on to cool down the vehicle head unit through a water circulation loop; obtaining the detected temperature information after a preset time period, where the detected temperature information includes real-time detected temperature values of at least one preset component collected by at least one temperature sensor after the preset time period; comparing the detected temperature information with a second preset threshold, and controlling the working state of the water circulation switch according to the comparison result. It solves the problems in the prior art that the water-cooled heat dissipation device causes too high water circulation temperature, the temperature of the controller system rises passively, the heat dissipation effect cannot be guaranteed, and the service life of the controller system is reduced. It can accurately and timely control the water circulation to enter and exit the controller system, ensure that the controller system can effectively dissipate heat, achieve the optimal heat dissipation effect, improve the user experience, and extend the service life of the controller system.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0052] Figure 1 The flowchart of a controller heat dissipation method provided by an embodiment of the present disclosure is shown, and the method may include the following steps:

[0053] S101: Obtain temperature information of multiple preset components of the vehicle head unit.

[0054] As an optional embodiment of the present disclosure, obtaining includes real-time temperature values of at least one preset component collected by at least one temperature sensor. Among them, obtaining temperature information of multiple preset components of the vehicle head unit is for the controller system to obtain real-time temperature values collected by the temperature sensor, and the real-time temperature values include, but are not limited to, at least one of the real-time temperature value of the MCU chip integrated inside the controller system, the real-time temperature value of the 5G module, the real-time temperature value of the SOC chip, and the real-time temperature value of the main board.

[0055] In this embodiment, the execution entity is a microcontroller unit (MCU) integrated in the controller system, also known as a single-chip microcomputer or a microcontroller. It appropriately reduces the frequency and specifications of the central processing unit (CPU), and integrates peripherals such as memory, timer, USB, A / D conversion, UART, PLC, DMA, and even the LCD driver circuit on a single chip to form a chip-level computer, which performs different combined controls for different application scenarios;

[0056] This control method can be applied to vehicles. Specifically, it is applied to the head unit (HU) integrated in the vehicle controller system. The controller system is an intelligent multimedia device integrated on the car console. Nowadays, with the development of networking and increasing demand functions, the controller system covers interactive content such as navigation, music, video, voice recognition, phone, information, etc., resulting in an increasing load and serious heat generation problems in the controller system. There is an urgent need for a controller heat dissipation control method to support the normal operation of the controller system with an increasing load, reduce the loss of the controller system, and increase the lifespan of the controller system.

[0057] S102: Compare the temperature information with a first preset threshold. If any real-time temperature value in the temperature information is greater than or equal to the first preset threshold, control the working state of the water circulation switch to be on to cool down the in-vehicle computer through the water circulation loop.

[0058] As an alternative embodiment of the present disclosure, the obtaining of the temperature information of multiple preset components of the in-vehicle computer includes: obtaining the real-time temperature value of the MCU module, the real-time temperature value of the SOC chip, the real-time temperature value of the 5G module, and the real-time temperature value of the main board; based on the comparison of the temperature information with a first preset threshold, if any of the real-time temperature values in the temperature information is greater than or equal to the first preset threshold, control the working state of the water circulation switch to be on. Specifically, compare the real-time temperature value of the MCU module, the real-time temperature value of the SOC chip, the real-time temperature value of the 5G module, and the real-time temperature value of the main board with the first preset threshold respectively. If any one or more of the real-time temperature values of the MCU module, the SOC chip, the 5G module, and the main board are greater than or equal to the first preset threshold, control the working state of the water circulation switch to be on to cool down the in-vehicle computer through the water circulation loop. When one or more of the multiple real-time temperature values collected by the above controller are greater than or equal to the first preset threshold, the operating temperature of the controller system is in a state that requires heat dissipation; when one or more of the multiple collected real-time temperature values are less than the first preset threshold, the operating temperature of the controller system is within the safe operating temperature range and no unnecessary heat dissipation is required. Optionally, the above first preset threshold can be any value between 0 and 40 °C and can be set according to specific heat dissipation requirements. The collected real-time temperature value is the real-time temperature value obtained by the temperature sensor collected by the controller system, and this real-time temperature value includes, but is not limited to, at least one of the real-time temperature value of the MCU chip integrated inside the controller system, the real-time temperature value of the 5G module, the real-time temperature value of the SOC chip, and the real-time temperature value of the main board. When any of the above real-time temperature values is greater than or equal to the first threshold, control the water circulation switch to open.

[0059] Optionally, the water circulation switch can be a three-way solenoid valve. When the collected real-time temperature value is greater than or equal to the first threshold, there is a risk of overheating in the controller system and there is a need for heat dissipation. Control the three-way solenoid valve switch to open and the water circulation starts for heat dissipation. The three-way solenoid valve has a high response speed and can quickly respond to the requirements of the water circulation switch for fast switching of the switch. At the same time, the internal structure of the three-way solenoid valve is compact, reducing the resistance of the fluid in the valve and improving the operating efficiency of the water circulation.

[0060] S103. Obtain the detected temperature information after a preset time period. The detected temperature information includes the real-time detected temperature values of at least one preset component collected by at least one temperature sensor after the preset time period.

[0061] As an alternative embodiment of the present disclosure, obtaining the detected temperature information after a preset time period is to detect whether the real-time temperature value changes. The plurality of real-time temperature values collected by the detection controller system are compared with the real-time temperature values collected at the previous time node to determine whether there is a deviation in the numerical values.

[0062] Optionally, the previous time node can be set. The time interval for collecting real-time temperature values can be set to continuous and uninterrupted collection, once per second, once per minute, etc. In other embodiments, it can be set arbitrarily according to the heat dissipation requirements, and no specific limitation is made here.

[0063] S104. Compare the detected temperature information with a second preset threshold, and control the working state of the water circulation switch according to the comparison result.

[0064] As an alternative embodiment of the present disclosure, comparing the detected temperature information with a second preset threshold and controlling the working state of the water circulation switch according to the comparison result includes: if any real-time detected temperature value in the detected temperature information after the preset time period is less than the second preset threshold, controlling the working state of the water circulation switch to be closed. Obtaining the detected temperature information after the preset time period includes obtaining the real-time detected temperature values of the MCU module, the SOC chip, the 5G module, and the main board after the preset time period; the step of if any real-time detected temperature value in the detected temperature information after the preset time period is less than the second preset threshold, controlling the working state of the water circulation switch to be closed includes: comparing the real-time detected temperature values of the MCU module, the SOC chip, the 5G module, and the main board after the preset time period with the second preset threshold; if any one or more of the real-time detected temperature values of the MCU module, the SOC chip, the 5G module, and the main board after the preset time period are less than the second preset threshold, controlling the working state of the water circulation switch to be closed. After a preset time period after the water circulation switch is turned on, the water circulation has been running for a period of time. The real-time temperature values of multiple preset components in the preset time period obtained in step S103 are compared with the second preset threshold. If any real-time temperature value is less than the second preset threshold, the water circulation switch is turned off. Optionally, the above second preset threshold can be any value between 0 and 40 °C and can be set according to specific heat dissipation requirements. The controller system collects the real-time temperature values obtained by at least one temperature sensor. The real-time temperature values after the preset time period include, but are not limited to, at least one of the real-time temperature values of the MCU chip integrated inside the controller system, the 5G module, the SOC chip, and the main board. When any of the above real-time temperature values is less than the second preset threshold, the water circulation switch is controlled to be turned off.

[0065] Optionally, the water circulation switch can be a three-way solenoid valve. When the collected real-time temperature value is less than the second threshold, the operating temperature of the controller system is within the normal operating temperature range and there is no need for heat dissipation. The three-way solenoid valve switch that is running is controlled to be closed, or the three-way solenoid valve that is in the closed state is controlled to disconnect the water circulation or keep the water circulation stopped, so as to avoid passive heating of the controller system caused by too high water circulation temperature.

[0066] Furthermore, a control line is used to connect the MCU and the three-way solenoid valve to control the three-way solenoid valve to respond to the control instruction. The three-way solenoid valve has a high response speed and can quickly respond to the requirements of the water circulation switch for fast switching of the switch. At the same time, the internal structure of the three-way solenoid valve is compact, reducing the resistance of the fluid in the valve and improving the operating efficiency of the water circulation.

[0067] Optionally, the real-time temperature value is obtained by a temperature sensor and sent to the MCU. The controller starts and runs normally. The MCU collects the real-time temperature value, which is the real-time temperature value obtained by the temperature sensor. After the temperature sensor obtains the real-time temperature value, the obtained real-time temperature value is sent to the MCU so that the MCU can collect the real-time temperature value. In practical applications, the temperature sensor and the MCU are integrated inside the controller system. The temperature sensor can be one or more. When the water circulation loop is connected to the controller system in series, the temperature sensor can be set to one to obtain the overall temperature of the controller system and send the obtained real-time temperature value to the MCU.

[0068] In another implementation, when the water circulation loop is connected to the controller system in parallel, multiple temperature sensors can be set and integrated into the heating modules inside the controller system respectively to separately obtain the real-time temperature values of the MCU chip, 5G module, SOC chip, and main board inside the controller system, and send the obtained real-time temperature values to the MCU.

[0069] As an optional embodiment of the present disclosure, after controlling the working state of the water circulation switch to be closed, continue to execute the step of obtaining the temperature information of multiple preset components of the vehicle head unit. Specifically, continuously obtain the temperature information of multiple preset components of the vehicle head unit and compare it with the first preset threshold. If any real-time temperature value in the temperature information is greater than or equal to the first preset threshold, control the working state of the water circulation switch to be open to cool down the vehicle head unit through the water circulation loop.

[0070] Specifically, after the working state of the water circulation loop is closed, continuously obtain the temperature information of multiple preset components of the vehicle head unit, monitor the real-time temperature, and determine whether there is a temperature value greater than the first preset threshold in the continuously obtained temperature information. If any real-time temperature value in the temperature information is greater than or equal to the first preset threshold, control the working state of the water circulation switch to be open to cool down the vehicle head unit through the water circulation loop.

[0071] In this embodiment, the provided controller heat dissipation method can be used to implement the corresponding controller heat dissipation control method. By presetting the first preset threshold and the second preset threshold, it is possible to control the water circulation to enter and exit the controller system in a timely manner, avoid passive heating of the controller system due to too high temperature of the water circulation system, ensure that the controller system can effectively dissipate heat, achieve the optimal heat dissipation effect, improve the user experience, and extend the service life of the controller system.

[0072] This application embodiment also provides a controller heat dissipation system, as Figure 2As shown in the figure, it includes: a controller, a water circulation switch, and a water circulation loop. The water circulation loop is in contact with the controller and is used for the water circulation loop to dissipate heat from the controller. The controller includes: at least one temperature sensor and an MCU module. Among them, the temperature sensor is integrally arranged at a preset position of the controller, and the MCU module is communicatively connected to the temperature sensor for obtaining temperature data information. The water circulation switch is arranged at a preset position, and the MCU module is connected to the water circulation switch through a control line for the MCU module to control the working state of the water circulation switch. The water circulation loop includes: an internal water circulation loop and an external water circulation loop. A valve body is arranged at the junction of the internal water circulation loop and the external water circulation loop in the water flow direction of the water circulation. The water circulation switch is communicatively connected to the valve body for controlling the opening and closing of different loops according to the working state of the water circulation switch.

[0073] As an optional embodiment of the present disclosure, the water circulation switch is integrally arranged in the controller or the water circulation switch is arranged outside the controller. When the water circulation switch is integrally arranged in the controller, it can reduce the waste of wiring and save resources. When the water circulation switch is arranged outside the controller, it is not necessary to change the layout of the original controller integrated board, but it will consume a corresponding number of wiring. Specifically, the position where the water circulation switch is arranged can be set according to actual needs and is not limited herein. In this embodiment, it is preferably to arrange the water circulation switch outside the controller.

[0074] As an optional embodiment of the present disclosure, the controller further includes: an SOC chip, a 5G module, and a main board. The MCU module, the SOC chip, the 5G module, and the main board are communicatively connected to the at least one temperature sensor. The temperature sensor is used to collect the temperature information of the MCU module, the SOC chip, the 5G module, and the main board. The controller cooling system can perform water cooling when there is a cooling requirement for the chips and modules inside the controller.

[0075] As an alternative embodiment of the present disclosure, the valve body is a three-way solenoid valve. The internal water circulation loop abuts against the controller. Water inlets and outlets communicating with the external water circulation loop are formed at both ends of the internal water circulation loop. The valve body is disposed at the water inlet between the internal water circulation loop and the external water circulation loop. The water circulation switch is communicatively connected to the valve body and is configured to, when the operating state of the water circulation switch is on, conduct the internal water circulation loop in contact with the controller, so that water circulation flows through the internal water circulation loop in contact with the controller, and the water circulation performs circulating heat dissipation in the internal water circulation loop; when the operating state of the water circulation switch is off, block the internal water circulation loop in contact with the controller, and prohibit the water circulation from flowing into the internal water circulation loop in contact with the controller, so that the water circulation performs circulating heat dissipation in the external water circulation loop. Wherein, the flow mode of the water circulation depends on the connection mode of the water circulation loop. In the embodiment of the present application, when the water circulation switch is turned on, the internal water circulation loop is conducted, and the water circulation loop can be connected into the controller system in series. After the water circulation loop is conducted, the water circulation flows through the part of the water circulation loop connected to the controller system to perform overall heat dissipation on the controller system; when the water circulation switch is turned off, the water circulation loop inside the controller is closed in parallel, the water circulation in the controller system is stopped, and the water circulation circulates in the external water circulation loop.

[0076] Based on the same inventive concept, as an implementation of the above method, an embodiment of the present application further provides a controller heat dissipation device. This embodiment corresponds to the foregoing method embodiment. For the convenience of reading, the details in the foregoing method embodiment will not be repeated one by one in this embodiment.
