[0002] With the development of the automotive industry and rising user demands, in-vehicle central control systems are becoming increasingly versatile. This has led to an increase in the area and size of the control panel, which in turn leads to operational complexity and safety risks for users. To address this issue, intelligent in-vehicle central control systems have been proposed that can be operated through intelligent voice and touch. This reduces the area and size of traditional in-vehicle central control systems.

[0003] However, the small size and area of ​​in-vehicle intelligent central control systems reduce their heat dissipation efficiency. Furthermore, since they are often installed in the vehicle's central control area and are subject to direct sunlight, they can experience high temperatures and difficulty dissipating heat. This negatively impacts the lifespan and operating efficiency of the in-vehicle intelligent central control system.

DETAILED DESCRIPTION

[0019] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0020] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0021] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0022] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0023] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0024] This application provides a heat dissipation method, such as Figure 1 As shown, the heat dissipation method provided in this application includes the following steps S1100 to S1300.

[0025] Step S1100 , obtaining the current operating temperature of the heat dissipation object and the current ambient temperature of the environment in which the heat dissipation object is located.

[0026] In one example, the heat dissipation object is an in-vehicle intelligent central control, a desktop personal computer host, etc.

[0027] For example, the heat dissipation target is an in-vehicle intelligent central control system. The current operating temperature of the heat dissipation target can be specifically the current temperature at the primary heat-generating location within the in-vehicle intelligent central control system, which can be collected by a first temperature sensor located at the aforementioned primary heat-generating location. The current ambient temperature of the heat dissipation target's environment is the current temperature of the vehicle's passenger space, which can be collected by a second temperature sensor located near the in-vehicle intelligent central control system within the vehicle's passenger space.

[0028] It is understandable that the current ambient temperature of the environment in which the heat dissipation object is located affects the current operating temperature and heat dissipation capacity of the heat dissipation object. In this regard, in one embodiment of the present application, the above step S1100 is specifically implemented through the following steps S1110 and S1111.

[0029] Step S1110 , obtaining the current ambient temperature of the environment in which the heat dissipation object is located.

[0030] Step S1111 : when the current ambient temperature is greater than or equal to the set ambient temperature, obtaining the current operating temperature of the heat dissipation object.

[0031] The set ambient temperature is the minimum ambient temperature at which the heat dissipation object cannot be automatically cooled. In one example, the set ambient temperature is 20°C. Based on this, it can be understood that if the current ambient temperature is greater than or equal to the set ambient temperature, it indicates that the current ambient temperature is too high and the heat dissipation object cannot be automatically cooled. In this case, the current operating temperature of the heat dissipation object is obtained to execute the following step S1200.

[0032] Corresponding to step S1111 above, if the current ambient temperature is lower than the set ambient temperature, it indicates that the current ambient temperature is relatively low and the current environment can automatically dissipate heat from the heat sink. In this case, there is no need to obtain the current operating temperature of the heat sink and proceed to step S1200 below. To prevent the ambient temperature from subsequently rising to a temperature greater than or equal to the set ambient temperature, step S1110 above is periodically executed when the current ambient temperature is lower than the set ambient temperature.

[0033] After the current operating temperature of the heat dissipation object and the current ambient temperature of the environment are obtained through the above step S1100, the following step S1200 is executed.

[0034] Step S1200: determining a current operating temperature limit of a heat dissipation object according to a current ambient temperature and at least two preset ambient temperature ranges.

[0035] Different preset ambient temperature ranges correspond to different operating limit temperatures, and each operating limit temperature is the maximum operating temperature of the heat dissipation object allowed by the environment under the corresponding preset ambient temperature.

[0036] In this application, the specific implementation of the above step S1200 is: according to the current ambient temperature and at least two preset ambient temperature ranges, the working limit temperature corresponding to the preset ambient temperature range where the current ambient temperature is located is determined as the current working limit temperature of the heat dissipation object.

[0037] It is understandable that the ambient temperature within different ambient temperature ranges directly affects the operating temperature and heat dissipation capacity of the heat dissipation object. If the same operating limit temperature is set for different ambient temperature ranges, then in a high-temperature environment, lowering the operating temperature of the heat dissipation object to the same operating limit temperature requires continuous operation, which results in a large amount of power consumption. Therefore, to avoid the continuous operation of the heat dissipation device in the heat dissipation object, which in turn causes a series of other problems such as high power consumption, different operating limit temperatures are set for different preset ambient temperature ranges to achieve a balance between heat dissipation efficiency and power consumption. In this way, the current operating limit temperature can be dynamically determined.

[0038] Regarding the above content, in one embodiment of the present application, for at least two preset ambient temperature ranges, the higher the ambient temperature represented by the preset ambient temperature range, the higher the working limit temperature corresponding to the preset ambient temperature range.

[0039] In one embodiment of the present application, the at least two preset ambient temperature ranges are a first ambient temperature range, a second ambient temperature range, and a third ambient temperature range, wherein each ambient temperature within the second ambient temperature range is lower than each ambient temperature within the third ambient temperature range and higher than each ambient temperature within the first ambient temperature range. In other words, three preset ambient temperature ranges are defined, thereby achieving a reasonable division of the preset ambient temperature ranges.

[0040] In this embodiment, the first ambient temperature range is recorded as [T1, T2), the second ambient temperature range is recorded as [T2, T3), and the third ambient temperature range is recorded as [T3, T4]. In one example, T1 is 20°C, T2 is 40°C, T3 is 60°C, and T4 is 80°C.

[0041] On the basis of the above embodiment, the above step S1200 is specifically implemented through the following steps S1210 to S1212.

[0042] Step S1210 : When the current ambient temperature is within a first ambient temperature range, determining that the current operating limit temperature of the heat dissipation object is the first operating limit temperature.

[0043] Step S1211 : when the current ambient temperature is within the second ambient temperature range, determining that the current operating limit temperature of the heat dissipation object is the second operating limit temperature.

[0044] Step S1212: When the current ambient temperature is within the third ambient temperature range, determine that the current operating limit temperature of the heat dissipation object is the third operating limit temperature.

[0045] The second operating limit temperature is greater than the first operating limit temperature and less than the third operating limit temperature.

[0046] In this embodiment, the first operating limit temperature, the second operating limit temperature and the third operating limit temperature can be determined based on the heat dissipation requirements and temperature resistance of the heat dissipation object, as well as the power consumption, heat dissipation efficiency and cost of the heat dissipation device that dissipates heat for the heat dissipation object.

[0047] The first operating limit temperature is recorded as Ta, the second operating limit temperature is recorded as Tb, and the third operating limit temperature is recorded as Tc. In one example, Ta is 20°C, Tb is 40°C, and Tc is 60°C.

[0048] Based on the above steps S1210 to S1211, different operating limit temperatures corresponding to different preset ambient temperature ranges can be specifically represented by the following Table 1.

[0049] Table 1

[0050] Through the above steps S1210 to S1212, a higher operating limit temperature can be set for the preset ambient temperature range that represents a higher ambient temperature, thereby ensuring a balance between the heat dissipation efficiency and power consumption of the heat dissipation device.

[0051] Step S1300 : controlling the operating state of the heat dissipation device in the heat dissipation object according to the current operating limit temperature and the current temperature difference between the current operating temperatures.

[0052] In this embodiment, a heat dissipation device is built into the heat dissipation object, which is used to dissipate heat from the heat dissipation object to reduce the current operating temperature of the heat dissipation object.

[0053] In one embodiment of the present application, the specific implementation principle of step S1300 may be: when the current temperature difference is greater, the operating state of the heat sink in the heat sink object is controlled to operate in a manner with higher heat dissipation efficiency. For example, a correspondence is set between different temperature difference ranges and different heat sink operating states, wherein the greater the temperature difference corresponding to the temperature difference range, the higher the heat dissipation efficiency corresponding to the heat sink operating state. It should be noted that as long as the specific implementation method meets this specific implementation principle, it is within the scope of protection of this application.

[0054] Through the above step S1300, while completing the heat dissipation of the heat dissipation object, the current temperature difference is dynamically calculated, thereby achieving reasonable and efficient control of the heat dissipation device.

[0055] Based on the above, the present application provides a heat dissipation method, which includes: obtaining the current operating temperature of the heat dissipation object and the current ambient temperature of the environment in which it is located; determining the current operating limit temperature of the heat dissipation object based on the current ambient temperature and at least two preset ambient temperature ranges, wherein different preset ambient temperature ranges correspond to different operating limit temperatures; and controlling the operating state of the heat dissipation device in the heat dissipation object based on the current operating limit temperature and the current temperature difference between the current operating temperatures. In this method, on the one hand, while completing the heat dissipation of the heat dissipation object, the current temperature difference can be dynamically calculated, thereby achieving reasonable and efficient control of the heat dissipation device. On the other hand, setting different operating limit temperatures for different preset ambient temperature ranges can achieve a balance between the heat dissipation efficiency and power consumption of the heat dissipation device, thereby avoiding a series of other problems such as high power consumption caused by the continuous operation of the heat dissipation device in the heat dissipation object.

[0056] In another embodiment of the present application, in order to implement the above step S1300, as shown in FIG. Figure 2 As shown, the heat dissipation method provided in the present application further includes the following steps S1310 and S1311 before the above step S1300.

[0057] Step S1310: determining a target ambient temperature range according to the current ambient temperature and at least two preset ambient temperature ranges.

[0058] Different preset ambient temperature ranges correspond to different heat dissipation device operation strategies, and each heat dissipation device operation strategy includes a correspondence between at least two heat dissipation device operation modes and temperature difference ranges.

[0059] Step S1311 : determining a heat dissipation device operation strategy corresponding to the target ambient temperature range as a target heat dissipation device operation strategy.

[0060] In this embodiment, the preset ambient temperature range in which the current ambient temperature is located among the at least two preset ambient temperature ranges is determined as the target ambient temperature range. Further, the heat dissipation device operation strategy corresponding to the target ambient temperature range is determined as the target heat dissipation device operation strategy.

[0061] On the basis of the above-mentioned step S1310 and step S1311, the above-mentioned step S1300 is specifically implemented through the following step S1320 and step S1330.

[0062] Step S1320 : determining the heat dissipation device operation mode corresponding to the temperature difference range of the current temperature difference in the target heat dissipation device operation strategy as the target heat dissipation device operation mode.

[0063] Step S1330 : controlling the operating state of the heat dissipation device in the heat dissipation object according to the target heat dissipation device operating mode.

[0064] In this embodiment, the heat dissipation capacity of the heat sink varies with ambient temperature. Specifically, the higher the ambient temperature, the lower the heat dissipation capacity of the heat sink. Therefore, different heat sink operation strategies are set for different preset ambient temperature ranges. Each heat sink operation strategy includes a correspondence between at least two heat sink operation modes and temperature difference ranges.

[0065] In one embodiment of the present application, for each heat sink operation strategy, different heat sink operation modes correspond to different heat dissipation efficiencies, and the higher the temperature difference represented by the temperature difference range, the higher the heat dissipation efficiency of the heat sink operation mode corresponding to the temperature difference range. For the same heat sink operation mode in different heat sink operation strategies, the preset ambient temperature range representing high ambient temperature corresponds to the temperature difference range corresponding to the heat sink operation mode in the heat sink operation strategy, which is a subset of the temperature difference range corresponding to the preset ambient temperature range representing low ambient temperature corresponds to the temperature difference range corresponding to the heat sink operation mode in the heat sink operation strategy. In this way, it can be achieved that for each heat sink operation strategy, the greater the temperature difference, the higher the heat dissipation efficiency of the heat sink, and it can be achieved that under the same heat sink operation mode, the higher the ambient temperature, the smaller the temperature difference that triggers the corresponding heat sink operation mode. In this way, reasonable heat dissipation of the heat dissipation object is achieved.

[0066] Regarding the above, in one embodiment of the present application, the at least two preset ambient temperature ranges are a first ambient temperature range, a second ambient temperature range, and a third ambient temperature range; each ambient temperature within the second ambient temperature range is less than each ambient temperature within the third ambient temperature range and greater than each ambient temperature within the first ambient temperature range; the heat sink includes a first heat sink and a second heat sink, and the heat dissipation efficiency of the second heat sink is greater than the heat dissipation efficiency of the first heat sink. Furthermore, the above-mentioned step S1320 is specifically implemented by the following steps S1321 to S1322.

[0067] Step S1321, when the target ambient temperature range is the first ambient temperature range, determines the target heat dissipation device operation strategy as follows: operate the first heat dissipation device when the current temperature difference is less than or equal to the first preset temperature difference and greater than 0, operate the second heat dissipation device when the current temperature difference is greater than the first preset temperature difference and less than or equal to the second preset temperature difference, operate the first heat dissipation device and the second heat dissipation device when the current temperature difference is greater than the second preset temperature difference, and stop operating the first heat dissipation device and the second heat dissipation device when the current temperature difference is equal to 0.

[0068] Step S1322, when the target ambient temperature range is the second ambient temperature range, determines the target heat dissipation device operation strategy as: operate the first heat dissipation device when the current temperature difference is less than or equal to the third preset temperature difference and greater than 0, operate the second heat dissipation device when the current temperature difference is greater than the third preset temperature difference and less than or equal to the fourth preset temperature difference, operate the first heat dissipation device and the second heat dissipation device when the current temperature difference is greater than the fourth preset temperature difference, and stop operating the first heat dissipation device and the second heat dissipation device when the current temperature difference is equal to 0.

[0069] The fourth preset temperature difference is smaller than the second preset temperature difference, and the third preset temperature difference is smaller than the first preset temperature difference.

[0070] Step S1323, when the target ambient temperature range is the third ambient temperature range, determine the target heat dissipation device operation strategy as follows: operate the first heat dissipation device when the current temperature difference is less than or equal to the fifth preset temperature difference and greater than 0, operate the second heat dissipation device when the current temperature difference is greater than the fifth preset temperature difference and less than or equal to the sixth preset temperature difference, operate the first heat dissipation device and the second heat dissipation device when the current temperature difference is greater than the sixth preset temperature difference, and stop operating the first heat dissipation device and the second heat dissipation device when the current temperature difference is equal to 0.

[0071] Among them, the fourth preset temperature difference is greater than the sixth preset temperature difference, and the third preset temperature difference is greater than the fifth preset temperature difference.

[0072] In one embodiment of the present application, the first heat sink is a miniature cooling fan, and the second heat sink is a semiconductor cooling module. Of course, the first and second heat sinks can also be other types of heat sinks, such as heat pipes and vapor chambers, as long as the heat dissipation efficiency of the second heat sink is higher than that of the first heat sink. Heat dissipation efficiency can be measured by the amount of heat dissipated per unit time.

[0073] Based on the above content, in the above steps S1321 to S1323, two heat dissipation devices can be used to achieve heat dissipation with three heat dissipation efficiencies, which can reduce the number of heat dissipation devices and further reduce the impact of the heat dissipation devices on the volume of the heat dissipation object.

[0074] In one example, the first preset temperature difference is 12°C, the second preset temperature difference is 18°C, the third preset temperature difference is 10°C, the fourth preset temperature difference is 15°C, the fifth preset temperature difference is 5°C, and the sixth preset temperature difference is 8°C.

[0075] For the above embodiment, the first preset temperature difference is recorded as t1, the second preset temperature difference is recorded as t2, the third preset temperature difference is recorded as t3, the fourth preset temperature difference is recorded as t4, the fifth preset temperature difference is recorded as t5, and the sixth preset temperature difference is recorded as t6. The current operating temperature of the heat dissipation object is recorded as Tw. When t1 is 12°C, t2 is 18°C, t3 is 10°C, t4 is 15°C, t5 is 5°C, and t6 is 8°C, and the heat dissipation device operation modes are heat dissipation device operation mode 1, heat dissipation device operation mode 2, heat dissipation device operation mode 3, and heat dissipation device operation mode 4 respectively, the heat dissipation device operation strategies of the heat dissipation devices corresponding to different preset ambient temperature ranges are specifically shown in Table 2 below.

[0076] Table 2

[0077] Based on Table 2 above, it can be seen that the higher the ambient temperature, the smaller the temperature difference between the heat sink that triggers the operation of the first heat sink and the second heat sink in the heat sink operation strategy corresponding to the preset ambient temperature range. For example, in the heat sink operation strategy corresponding to the first ambient temperature range, the first heat sink is operated when 0<Tw-Ta≤t1, while in the heat sink operation conditions corresponding to the second ambient temperature range, the first heat sink is operated when 0<Tw-Ta≤t2, and t2 is less than t1. That is, the temperature difference between the heat sink that triggers the operation of the first heat sink and the second heat sink is adjusted dynamically according to the ambient temperature. And, at the same preset ambient temperature, the greater the temperature difference, the greater the heat dissipation efficiency of the heat sink. In this way, reasonable heat dissipation of the heat dissipation object can be achieved.

[0078] In combination with the above content, for the above step S1330, in an example, when the target ambient temperature range is [20℃, 40℃), when the current temperature difference is 0℃, the first heat dissipation device and the second heat dissipation device are controlled to stop running; when the current temperature difference is greater than 0℃ and less than or equal to 12℃, the first heat dissipation device is controlled to run; when the current temperature difference is greater than 12℃ and less than or equal to 18℃, the second heat dissipation device is controlled to run; when the current temperature difference is greater than 18℃, the first heat dissipation device and the second heat dissipation device are controlled to run.

[0079] In another example, when the target ambient temperature range is [40°C, 60°C), when the current temperature difference is 0°C, the first heat dissipation device and the second heat dissipation device are controlled to stop operating; when the current temperature difference is greater than 0°C and less than or equal to 10°C, the first heat dissipation device is controlled to operate; when the current temperature difference is greater than 10°C and less than or equal to 15°C, the second heat dissipation device is controlled to operate; when the current temperature difference is greater than 15°C, the first heat dissipation device and the second heat dissipation device are controlled to operate.

[0080] In another example, when the target ambient temperature range is [60°C, 80°C), when the current temperature difference is 0°C, the first heat dissipation device and the second heat dissipation device are controlled to stop operating; when the current temperature difference is greater than 0°C and less than or equal to 5°C, the first heat dissipation device is controlled to operate; when the current temperature difference is greater than 5°C and less than or equal to 8°C, the second heat dissipation device is controlled to operate; when the current temperature difference is greater than 8°C, the first heat dissipation device and the second heat dissipation device are controlled to operate.

[0081] The present application also provides a heat dissipation device 300, such as Figure 3 As shown, the device 300 includes: An acquisition module 310 is used to acquire the current operating temperature of the heat dissipation object and the current ambient temperature of the environment in which the heat dissipation object is located; a determination module 320 configured to determine a current operating limit temperature of the heat dissipation object based on the current ambient temperature and at least two preset ambient temperature ranges, wherein different preset ambient temperature ranges correspond to different operating limit temperatures; The control module 330 is configured to control the operating state of the heat dissipation device in the heat dissipation object according to the current operating limit temperature and the current temperature difference between the current operating temperatures.
