Description

Technical Field

[0001] The present disclosure relates to controller technology, and more specifically, to a heat dissipation control method, device, electronic device, controller heat dissipation system and vehicle. Background Art

[0002] With the development of automobile intelligence and electrification, automobile multifunctionality is becoming increasingly obvious. With the increase of automobile functions, the integration of automobile domain controllers is getting higher and higher, which makes the chip power consumption of automobile domain controllers higher and higher, and then leads to the chip heat generation of automobile domain controllers. For the needs of dust and water resistance, many devices of automobile domain controllers are concentrated in a highly sealed shell. The air flow in the shell is poor. Some devices with large heat generation, such as SOC (System on Chip, circuit system), CPU (Central Processing Unit, central processing unit), GPU (Graphics Processing Unit, graphics processor), etc., need to continuously output powerful computing power during work, and the power consumption is increasing, causing the temperature of the chip part to rise. If the heat generated by SOC, CPU, GPU, etc. is not dissipated in time during work, it will affect the performance and life of the chip, and even cause device damage, affecting driving safety.

[0003] In the prior art, the heat on the chip is transferred to the heat sink by fitting the heat sink closely to the chip, and then the heat is transferred to the outside air through the heat sink to achieve the purpose of cooling the chip. In order to speed up the heat dissipation, a fan is installed on the existing domain controller to accelerate the heat dissipation by pushing the air flow. Alternatively, a liquid circulation pipe is added to the heat dissipation surface of the domain controller to remove the heat through the liquid flow to speed up the heat dissipation.

[0004] The above solution of installing a fan on the domain controller increases the fan cost and the fan control circuit cost, and the fan operation will increase the power consumption and noise of the entire domain controller system. The solution of adding a liquid circulation pipeline to the heat dissipation surface of the domain controller increases the cost of the liquid cooling control circuit and the coolant cost, and the liquid cooling solution also makes the entire domain control system more complicated.

[0048] Various exemplary embodiments of the present specification will now be described in detail with reference to the accompanying drawings.

[0049] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the embodiments of the present specification and its application or uses.

[0050] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0051] In one embodiment of the present invention, a controller heat dissipation system is provided for dissipating heat from a vehicle controller. Figure 1 As shown, the controller heat dissipation system includes a controller and an air duct. The air duct is used to communicate with the air conditioning system of the vehicle, and the air duct is used to use the air conditioning system to dissipate heat for the controller.

[0052] The controller heat dissipation system provided by the present invention utilizes the air conditioning system to dissipate heat for the controller through the air duct, thereby achieving cooling of the controller. Meanwhile, based on the original structure, only the air duct needs to be added, and the structural modification is relatively simple and the cost is low.

[0053] In one embodiment, the controller is disposed in the air duct, or the air outlet of the air duct is disposed toward the controller, or one end of the air outlet of the air duct is connected to the controller.

[0054] In one embodiment, the air duct is used to communicate with an air outlet of an air conditioning system.

[0055] The air conditioning system includes a plurality of air outlets, for example, a driver's side air outlet, a passenger's side air outlet, and a rear seat air outlet. The air duct may be connected to at least one of the air outlets of the air conditioning system.

[0056] In one embodiment, the controller heat dissipation system further includes a damper. The damper is used to adjust the air intake of the air duct. The damper is arranged on the air duct.

[0057] Specifically, the damper may be arranged on the air duct, close to the air outlet of the air conditioning system.

[0058] Specifically, the command for adjusting the degree of opening of the damper can be sent to the damper control motor. The damper control motor adjusts the degree of opening of the damper according to the command. The command for adjusting the degree of opening of the damper can be a command for increasing the degree of opening of the damper or a command for decreasing the degree of opening of the damper.

[0059] By setting the damper, the air volume of the air duct can be adjusted to meet different heat dissipation requirements. When the heat dissipation requirement is high, for example, the time for the chip temperature value to drop to the preset temperature value does not exceed the preset time, the damper opening degree can be increased to increase the air volume of the air duct and accelerate the heat dissipation.

[0060] In one embodiment, the controller includes a controller body and a heat sink disposed on the body. The heat sink may be an aluminum alloy metal plate. The inner side of the heat sink is in close contact with the controller body through thermally conductive silica gel. The outer side of the heat sink faces the air outlet of the air duct, or the outer side of the heat sink is connected to one end of the air outlet of the air duct, so that the outer side of the heat sink contacts the air outlet of the air conditioning system through the air duct.

[0061] In one embodiment, the controller comprises a domain controller and / or a central controller.

[0062] Figure 2 FIG. 2 shows a schematic diagram of the structure of a controller heat dissipation system according to an embodiment of the present invention. Figure 2 As shown, the controller heat dissipation system includes a controller 210 and an air duct 220 .

[0063] Figure 2 The air conditioning system 230 is also shown. The air conditioning system 230 includes three air outlets, a driver's side air outlet 231 , a passenger's side air outlet 232 , and a rear seat air outlet 233 .

[0064] See also Figure 2 The first end of the air duct 220 is connected to the main driver's side air outlet 231, the passenger side air outlet 232, and the rear seat air outlet 233. The second end of the air duct 220 is connected to the controller 210.

[0065] In this embodiment, the air from the three air outlets of the air conditioning system 230 is introduced into the controller 210 through the air duct 220 to cool the controller 210 and achieve heat dissipation of the controller 210.

[0066] In this embodiment, the controller cooling system also includes three dampers ( Figure 2 The first air door is used to adjust the amount of air entering the air duct 220 from the main passenger side air outlet 231. The second air door is used to adjust the amount of air entering the air duct 220 from the passenger side air outlet 232. The third air door is used to adjust the amount of air entering the air duct 220 from the rear seat air outlet 233.

[0067] In this embodiment, by controlling the opening state of the three dampers, the air outlet of at least one of the three air outlets of the air conditioning system 230 can be introduced into the controller 210 through the air duct 220, so as to cool the controller 210 and achieve heat dissipation of the controller 210. In addition, by controlling the opening degree of the three dampers, the air intake of the air duct 220 can be adjusted to meet different heat dissipation requirements. When the heat dissipation requirement is high, for example, the time length for the chip temperature value to drop to the preset temperature value does not exceed the preset time length, the damper opening degree can be increased, thereby increasing the air intake of the air duct and accelerating the heat dissipation.

[0068] In one embodiment of the present invention, a heat dissipation control method is provided, which is applied to a controller heat dissipation system as provided in any of the above embodiments. Figure 3 As shown, the heat dissipation control method of this embodiment may include the following steps S310 to S320.

[0069] Step S310, obtaining temperature information of the controller.

[0070] The controller includes one or more chips. The temperature information includes temperature values ​​of the one or more chips.

[0071] Each chip is provided with a temperature sensor. The temperature sensor can collect the temperature value of the chip. Specifically, the temperature value of the chip collected by the temperature sensor is read through the SPI communication interface or the IIC communication interface.

[0072] Step S320, when it is determined according to the temperature information of the controller that the controller needs to dissipate heat, the working state of the air conditioning system and / or the air duct is controlled so that the air duct uses the air conditioning system to dissipate heat for the controller.

[0073] The situation where the controller needs to dissipate heat includes that the temperature value of at least one chip among the one or more chips exceeds a preset temperature value. The preset temperature value can be set according to demand.

[0074] The heat dissipation control method provided in an embodiment of the present invention controls the working state of the air-conditioning system and / or the air duct so that the air duct utilizes the air-conditioning system to dissipate heat for the controller, thereby achieving cooling of the controller when the temperature information of the controller determines that the controller needs heat dissipation.

[0075] In one embodiment, step S320 specifically includes at least one of the following steps: controlling the air-conditioning system to cool so that the air duct uses the air-conditioning system to dissipate heat for the controller; controlling the speed of the fan of the air-conditioning system to make the gas in the air duct flow so that the air duct uses the air-conditioning system to dissipate heat for the controller; controlling the damper of the air duct to be in an open state so that the air duct uses the air-conditioning system to dissipate heat for the controller.

[0076] The cooling power of the air conditioning system is determined based on the temperature information; and / or the speed of the fan is determined based on the temperature information; and / or the damper opening is determined based on the temperature information.

[0077] When the temperature value of at least one chip among one or more chips exceeds a preset temperature value, the cooling power of the air-conditioning system is adjusted, and / or the speed of the fan and / or the damper opening are adjusted according to the difference between the temperature value of the chip and the preset temperature value.

[0078] Specifically, when the difference between the temperature value of the chip and the preset temperature value exceeds the preset difference, the cooling power of the air conditioning system can be increased, and / or the speed of the fan can be increased, and / or the damper opening can be increased to accelerate heat dissipation. When the difference between the temperature value of the chip and the preset temperature value does not exceed the preset difference, the cooling power of the air conditioning system, the speed of the fan, and the damper opening remain unchanged.

[0079] In one embodiment, the method further includes: when the temperature information of the controller determines that the controller does not need to dissipate heat and the air conditioning system has turned on the in-vehicle cooling mode, controlling the air duct to be in a closed state.

[0080] The in-car cooling mode is a mode for cooling the cabin space.

[0081] When the temperature information of each controller determines that the controller does not need to dissipate heat, the air duct is controlled to be in a closed state, so that the air outlet of the air-conditioning system is completely used for cooling the vehicle compartment space.

[0082] In one embodiment, the method further includes: when the air conditioning system has turned on the in-vehicle heating mode, controlling the air duct to be in a closed state.

[0083] The in-car heating mode is a mode for heating the vehicle cabin space.

[0084] When the air conditioning system has turned on the in-car heating mode, the air outlet of the air conditioning system is hotter, and the control air duct is in a closed state to prevent the hotter air from entering the controller, causing the temperature of the controller to rise and affecting the normal use of the controller.

[0085] In one embodiment, before controlling the air conditioning system to perform a cooling operation, the method further includes: detecting whether the air conditioning system is in a vehicle cooling mode. If the air conditioning system is in a vehicle cooling mode, increasing the cooling power of the air conditioning system, and / or increasing the speed of the fan of the air conditioning system, and / or increasing the damper opening of the air duct, so that the air duct uses the air conditioning system to dissipate heat for the controller.

[0086] In this embodiment, when the air-conditioning system has turned on the in-vehicle cooling mode, the air volume of the air outlet of the air-conditioning system must meet both the cooling needs of the vehicle compartment and the heat dissipation needs of the controller. Therefore, increasing the cooling power of the air-conditioning system, and / or increasing the speed of the fan of the air-conditioning system, and / or increasing the damper opening of the air duct so that the air duct uses the air-conditioning system to dissipate heat for the controller can meet the above two needs.

[0087] In this embodiment, when the air-conditioning system does not turn on the in-vehicle cooling mode, the air outlet of the air-conditioning system only needs to meet the heat dissipation requirements of the controller. At this time, the air-conditioning system is controlled to cool, and / or the speed of the fan of the air-conditioning system is controlled to make the gas in the air duct flow, and / or the damper of the air duct is controlled to be in an open state, so that the air duct uses the air-conditioning system to dissipate heat for the controller.

[0088] In one embodiment, the method also includes: obtaining temperature information of the controller at a preset time after the air duct utilizes the air conditioning system to dissipate heat for the controller; when the temperature value of at least one chip among the one or more chips still exceeds the preset temperature value, increasing the cooling power of the air conditioning system, and / or increasing the speed of the fan of the air conditioning system, and / or increasing the damper opening of the air duct.

[0089] At a preset moment after the air-conditioning system is used to dissipate heat for the controller through the air duct, the temperature value of at least one chip among the one or more chips still exceeds the preset temperature value, indicating that the current heat dissipation operation cannot meet the heat dissipation requirements of the controller. Therefore, in this embodiment, the cooling power of the air-conditioning system is increased, and / or the speed of the fan of the air-conditioning system is increased, and / or the damper opening of the air duct is increased to accelerate the heat dissipation of the controller.

[0090] The heat dissipation control method provided by the present invention is described below with a specific embodiment. In this embodiment, the controller includes a plurality of chips.

[0091] See also Figure 4 , the heat dissipation control method includes steps S401 to S406.

[0092] Step S401, obtaining the temperature value of each chip of the controller.

[0093] Step S402 , detecting whether the temperature value of at least one chip exceeds a preset temperature value.

[0094] When the detection result of step S402 is yes, step S403 is executed to detect whether the air-conditioning system is turned on the vehicle cooling mode.

[0095] When the detection result of step S403 is no, execute step S404 to control the air-conditioning system to cool, and / or control the speed of the fan of the air-conditioning system to make the gas in the air duct flow, and / or control the damper of the air duct to be in an open state so that the air duct uses the air-conditioning system to dissipate heat for the controller.

[0096] When the detection result of step S403 is yes, execute step S405 to increase the cooling power of the air-conditioning system, and / or increase the speed of the fan of the air-conditioning system, and / or increase the damper opening of the air duct, so that the air duct uses the air-conditioning system to dissipate heat for the controller.

[0097] When the detection result of step S402 is no, step S406 is executed to dissipate heat for the controller without using the air conditioning system through the air duct.

[0098] An embodiment of the present invention provides a heat dissipation control device, such as Figure 5 The heat dissipation control device 500 includes an acquisition module 510 and a control module 520 .

[0099] The acquisition module 510 is used to acquire temperature information of the controller.

[0100] The control module 520 is used to control the working state of the air conditioning system and / or the air duct when it is determined according to the temperature information of the controller that the controller needs to dissipate heat, so that the air duct uses the air conditioning system to dissipate heat for the controller.

[0101] In one embodiment, the controller includes one or more chips, the temperature information includes temperature values ​​of the one or more chips, and the situation where the controller needs to dissipate heat includes: the temperature value of at least one chip among the one or more chips exceeds a preset temperature value.

[0102] In one embodiment, the control module 520 is also used to control the cooling of the air-conditioning system so that the air duct uses the air-conditioning system to dissipate heat for the controller; and / or control the speed of the fan of the air-conditioning system to make the gas in the air duct flow so that the air duct uses the air-conditioning system to dissipate heat for the controller; and / or control the damper of the air duct to be in an open state so that the air duct uses the air-conditioning system to dissipate heat for the controller.

[0103] In one embodiment, the cooling power of the air-conditioning system is determined based on the temperature information; and / or the speed of the fan is determined based on the temperature information; and / or the damper opening is determined based on the temperature information.

[0106] In one embodiment, the heat dissipation control device further includes a detection module 530. The detection module 530 is used to detect whether the air conditioning system is in the vehicle cooling mode.

[0107] In this embodiment, when the detection module 530 detects that the air-conditioning system has turned on the in-vehicle cooling mode, the control module is also used to increase the cooling power of the air-conditioning system, and / or increase the speed of the fan of the air-conditioning system, and / or increase the damper opening of the air duct, so that the air duct uses the air-conditioning system to dissipate heat for the controller.
