Description
Technical Field
[0001] This application belongs to the field of vehicle controller heat dissipation technology, and specifically relates to a vehicle air conditioning temperature control system and vehicle. Background Technology
[0002] The extreme operating environments for vehicle controllers are generally in summer and winter. In summer, due to the high ambient temperature, vehicle controllers need to be cooled. Currently, there are two common cooling methods: natural cooling and fan cooling. However, each of these methods has its own problems. Natural cooling has low heat dissipation capacity and is suitable for vehicle controllers with low heat dissipation. With the increase in computing power of entertainment host, the heat dissipation is increasing day by day, and natural cooling cannot meet the heat dissipation requirements. Fan cooling can meet the heat dissipation capacity requirements, but as a moving part, the fan generates noise and vibration during operation, which reduces the product life cycle and has low reliability. Moreover, when the fan is damaged, it is difficult for car owners to replace or repair it themselves.
[0003] In winter, the external environment is relatively cold. If the external environment can provide heat to the entertainment controller, it will help the chip operate within a suitable temperature range, which is more conducive to the stable performance of the entertainment controller. Currently, there is no similar configuration in vehicle controllers.
[0004] Therefore, it is desirable to have a technical solution to overcome or at least mitigate one of the aforementioned defects of the prior art. Summary of the Invention

[0030] The vehicle air conditioning temperature control system of this application employs passive heat dissipation through gravity capillary action.

The embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0036] It should be noted that in the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

Figure 2 This is a schematic diagram of the vehicle air conditioning temperature control system provided in the second embodiment of this application.
[0038] like Figure 1 The vehicle air conditioning temperature control system shown includes a vehicle air conditioning system 1 and a gravity heat pipe assembly 2.
[0039] The vehicle air conditioning system includes an air outlet duct 1;
[0040] One end of the gravity heat pipe assembly 2 is disposed inside the air outlet duct 1, and the other end of the gravity heat pipe assembly is disposed on the vehicle controller 3 for the entertainment host; wherein...
[0041] When the vehicle air conditioning system is working, the gas generated by the vehicle air conditioning system exchanges heat with the gravity heat pipe assembly at the ventilation duct.
[0042] The vehicle air conditioning temperature control system of this application employs passive heat dissipation through gravity capillary action. In summer, heat within the vehicle controller of the entertainment host is transferred to the heat dissipation unit within the air conditioning duct via a gravity heat pipe assembly. The cool air in the air conditioning duct then carries away the heat from the heat dissipation unit, thus achieving heat dissipation for the controller. Since the gravity heat pipe itself is not a moving part, it does not generate noise or vibration, resulting in significantly improved reliability compared to fan-based cooling. In winter, hot air from the exhaust duct transfers heat to the vehicle controller of the entertainment host via the gravity heat pipe assembly, warming the controller and ensuring it operates at a reasonable temperature, thus guaranteeing the low-temperature reliability of the entertainment controller.
[0043] In this embodiment, the gravity heat pipe assembly includes a heat pipe body 21 and a first heat dissipation part 22. The first heat dissipation part 22 is disposed in the air outlet duct 1. The first heat dissipation part 22 is connected to one end of the heat pipe body 21, and the other end of the heat pipe body 21 is connected to the vehicle controller 3 for the entertainment host.
[0044] By incorporating a heat dissipation section, the contact area between the gas in the air outlet duct and the gravity heat pipe assembly can be significantly increased, thereby achieving efficient heat transfer.
[0045] In this embodiment, the first heat dissipation part 22 includes a base plate 221 and a heat dissipation plate 222, and the base plate 221 is connected to the heat pipe body 21.
[0046] The number of heat sinks 222 is at least two, and each heat sink 222 is connected to the base plate.
[0047] See Figure 2 In this embodiment, the first heat dissipation part 22 further includes a heat dissipation support plate 223, which is disposed on each heat dissipation plate 222.
[0048] In this embodiment, the base plate 221, the heat sink 222, and the heat sink support plate 223 are all hollow structures;
[0049] One or more of the heat sink 222, the base plate 221, and the heat sink support plate 223 are provided with air inlets; wherein...
[0050] When gas from the vehicle air conditioning system enters the air outlet duct, the gas can enter one of the heat sink, base plate, or heat sink support plate through the air inlet.
[0051] By setting air inlets, some air can enter the heat sink, base plate, and heat sink support plate, thereby achieving better heat exchange.
[0052] In this embodiment, the heat source of the entertainment host mainly consists of the commonly used chip heat source and other electronic components requiring heat dissipation in the vehicle controller of the entertainment host. The gravity capillary heat pipe is the main heat conduction part, transferring the heat inside the entertainment host to the heat exchange system inside the air conditioning duct through the phase change heat of the liquid inside the heat pipe. The heat of the heat exchange system is then carried away by the cold air in the air conditioning duct. In winter, the air conditioning duct contains hot air. In this case, because the outer part of the heat pipe is metal, it can conduct heat to the entertainment controller, achieving the purpose of heating and increasing the temperature of the entertainment controller, which is beneficial for the operation of the entertainment controller at low temperatures.
[0053] In this embodiment, the vehicle air conditioning temperature control system further includes a first temperature sensor and a main controller. The first temperature sensor is mounted on the vehicle controller; the main controller is connected to both the vehicle air conditioning system and the temperature sensor.
[0054] The main controller is used to acquire the temperature information of the vehicle controller and transmit control signals to the vehicle air conditioning system based on the temperature information of the vehicle controller.
[0055] The vehicle air conditioning system operates according to the control signal, thereby enabling the gas generated by the vehicle air conditioning system to exchange heat with the gravity heat pipe assembly at the ventilation duct.
[0056] In some cases, the vehicle user may not have turned on the air conditioning. In such cases, if the weather is extreme, the infotainment system's onboard controller may not be able to dissipate heat effectively. In this situation, by using the first sensor to detect the temperature of the infotainment system's onboard controller, the temperature can be controlled when the temperature exceeds a preset threshold, such as by heating or cooling the infotainment system's onboard controller.
[0057] In this embodiment, the vehicle air conditioning temperature control system further includes a solenoid valve, which is disposed in the air outlet duct and is used to regulate the flow rate of the gas supplied from the air outlet duct.
[0058] By setting the flow solenoid valve, heating or cooling can be controlled according to specific circumstances. For example, when it is necessary to cool down the vehicle controller for the entertainment head unit, but the user does not want the temperature inside the vehicle to be too low, reducing the flow rate can both ensure that the temperature of the vehicle controller for the entertainment head unit is not too high and prevent the temperature inside the vehicle from being too low.
[0059] In one embodiment, the vehicle air conditioning temperature control system further includes:
[0060] The second temperature sensor is disposed within the central hole structure of the base plate and connected to the main controller. The second temperature sensor is used to detect the temperature inside the base plate and transmit the temperature information inside the base plate to the main controller.
[0061] By setting up a second temperature sensor and a first temperature sensor, the heat transfer rate can be obtained.
[0062] In this embodiment, a display device may also be provided, which is connected to the main controller to display the current heat exchange rate.
[0063] In this embodiment, there are multiple gravity heat pipe assemblies.
[0064] This application also provides a method for controlling the temperature of a vehicle air conditioner, the method comprising:
[0065] Obtain the temperature of the vehicle's onboard controller for the entertainment system;
[0066] Determine whether the temperature exceeds a first preset temperature threshold or falls below a second preset temperature threshold. If so, then...
[0067] A control signal is generated and sent to the vehicle air conditioning system. The vehicle air conditioning system operates according to the control signal, thereby exchanging heat between the gas generated by the vehicle air conditioning system and the gravity heat pipe assembly at the ventilation duct to lower or raise the temperature of the vehicle controller for the entertainment host.
[0068] In this embodiment, the vehicle air conditioning temperature control method of this application further includes:
[0069] Obtain the temperature transmitted by the first temperature sensor;
[0070] Obtain the temperature transmitted by the second temperature sensor;
[0071] The heat exchange efficiency is obtained based on the temperature transmitted by the first temperature sensor and the temperature transmitted by the second temperature sensor.
[0072] In this embodiment, the heat exchange efficiency = temperature transmitted by the first temperature sensor / temperature transmitted by the second temperature sensor × 100%.
[0073] In this embodiment, the present application also provides a main controller, which includes a temperature acquisition module, a judgment module, and a control signal judgment module, wherein,
[0074] The temperature acquisition module is used to acquire the temperature of the vehicle controller used in the entertainment host.
[0075] The judgment module is used to determine whether the temperature exceeds a first preset temperature threshold or is lower than a second preset temperature threshold;
[0076] The control signal judgment module is used to generate a control signal and send it to the vehicle air conditioning system when the judgment module determines that it is true. The vehicle air conditioning system operates according to the control signal, thereby exchanging heat between the gas generated by the vehicle air conditioning system and the gravity heat pipe assembly at the ventilation duct to reduce or increase the temperature of the vehicle controller for the entertainment host.
