In order to solve this problem, a vehicle-mounted intelligent central control that can be operated by intelligent voice and intelligent touch is proposed. In this way, the area and volume of the vehicle-mounted intelligent central control are reduced compared with the traditional vehicle-mounted central control.

[0003] However, the small volume and small area of the vehicle-mounted intelligent central control will lead to the reduction of the heat dissipation efficiency of the vehicle-mounted intelligent central control. In addition, the vehicle-mounted intelligent central control is often installed in the central control area of the vehicle and is easily exposed to direct sunlight. Therefore, the vehicle-mounted intelligent central control has the problems of high temperature and difficult heat dissipation.

[0048] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Thus, other examples of the exemplary embodiments can have different values.

[0049] It should be noted that like reference numerals and letters refer to like items throughout the attached drawings, and thus once an item is defined in one drawing, it is not necessary that it be further discussed in subsequent drawings.

[0050] The present application provides a heat dissipation method, such as Figure 1 As shown in the figure, the heat dissipation method provided by the present application comprises the following steps S1100 to S1300.

[0051] Step S1100, obtaining the current working temperature of the heat dissipation object and the current environmental temperature of the environment where the heat dissipation object is located.

[0052] In one example, the heat dissipation object is a vehicle-mounted intelligent central control, a desktop personal computer host, etc.

[0053] Taking the vehicle-mounted intelligent central control as an example, the current working temperature of the heat dissipation object can be specifically the current temperature at the main heat generating position inside the vehicle-mounted intelligent central control, which can be collected by the first temperature sensor arranged at the main heat generating position. The current environmental temperature of the environment where the heat dissipation object is located is the current temperature of the vehicle's passenger space, which can be collected by the second temperature sensor arranged near the vehicle-mounted intelligent central control in the vehicle's passenger space.

[0054] It can be understood that the current environmental temperature of the environment where the heat dissipation object is located affects the current working temperature and the 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.

[0055] Step S1110, obtaining the current environmental temperature of the environment where the heat dissipation object is located.

[0056] Step S1111, obtaining the current working temperature of the heat dissipation object in the case that the current environmental temperature is greater than or equal to the set environmental temperature.

[0057] The set environment temperature is the minimum environment temperature when the heat dissipation object cannot be automatically cooled. In an example, the set environment temperature is 20℃. Based on this, it can be understood that when the current environment temperature is greater than or equal to the set environment temperature, it indicates that the current environment temperature is too high, and the current environment cannot automatically cool the heat dissipation object. At this time, the current working temperature of the heat dissipation object is obtained to perform the following step S1200.

[0058] Corresponding to the above step S1111, when the current environment temperature is less than the set environment temperature, it indicates that the current environment temperature is relatively low, and the current environment can automatically cool the heat dissipation object. At this time, there is no need to obtain the current working temperature of the heat dissipation object to perform the following step S1200. In order to avoid the subsequent environment temperature rising to a temperature greater than or equal to the set environment temperature, the above step S1110 is periodically performed when the current environment temperature is less than the set environment temperature.

[0059] After obtaining the current working temperature of the heat dissipation object and the current environment temperature of the environment through the above step S1100, the following step S1200 is performed.

[0060] In step S1200, the current working temperature limit of the heat dissipation object is determined according to the current environment temperature and at least two preset environment temperature ranges.

[0061] Different preset environment temperature ranges correspond to different working limit temperatures, and each working limit temperature is the highest working temperature of the heat dissipation object allowed by the environment at the corresponding preset environment temperature.

[0062] In the present application, the specific implementation of the above step S1200 is: according to the current environment temperature and at least two preset environment temperature ranges, the working limit temperature corresponding to the preset environment temperature range in which the current environment temperature is located is determined as the current working limit temperature of the heat dissipation object.

[0063] It can be understood that the environment temperature of different environment temperature ranges directly affects the working temperature and cooling capacity of the heat dissipation object. If the same working limit temperature is set for different environment temperature ranges, then in a high-temperature environment, the working temperature of the heat dissipation object needs to be reduced to the same working limit temperature, which requires continuous work, resulting in the need to consume a large amount of power consumption. Therefore, in order to avoid the continuous work of the heat dissipation device in the heat dissipation object causing a series of problems such as high power consumption, different working limit temperatures are set for different preset environment temperature ranges to balance the cooling efficiency and power consumption. In this way, the current working limit temperature can be dynamically determined.

[0064] For the above, in an embodiment of the present application, for at least two preset ambient temperature ranges, the higher the ambient temperature characterized by the preset ambient temperature range, the higher the working limit temperature corresponding to the preset ambient temperature range.

[0065] In an 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 in the second ambient temperature range is less than each ambient temperature in the third ambient temperature range and greater than each ambient temperature in the first ambient temperature range. That is, three preset ambient temperature ranges are divided, which can realize reasonable division of the preset ambient temperature ranges.

[0066] In the embodiment, the first ambient temperature range is denoted as [T1, T2), the second ambient temperature range is denoted as [T2, T3), and the third ambient temperature range is denoted as [T3, T4). In an example, T1 is 20℃, T2 is 40℃, T3 is 60℃, and T4 is 80℃.

[0067] On the basis of the above embodiment, the above step S1200 is specifically implemented through the following steps S1210 to S1212.

[0068] Step S1210, in the case that the current ambient temperature is located in the first ambient temperature range, determining the current working limit temperature of the heat dissipation object as the first working limit temperature.

[0069] Step S1211, in the case that the current ambient temperature is located in the second ambient temperature range, determining the current working limit temperature of the heat dissipation object as the second working limit temperature.

[0070] Step S1212, in the case that the current ambient temperature is located in the third ambient temperature range, determining the current working limit temperature of the heat dissipation object as the third working limit temperature.

[0071] Wherein, the second working limit temperature is greater than the first working limit temperature and less than the third working limit temperature.

[0072] In the embodiment, the first working limit temperature, the second working limit temperature and the third working limit temperature can be determined according to the heat dissipation demand and temperature resistance capability of the heat dissipation object, and the power consumption, heat dissipation efficiency and cost of the heat dissipation device dissipating heat for the heat dissipation object.

[0073] And, the first working limit temperature is denoted as Ta, the second working limit temperature is denoted as Tb, and the third working limit temperature is denoted as Tc. In an example, Ta is 20℃, Tb is 40℃, and Tc is 60℃.

[0074] Based on the above steps S1210 to S1211, the different preset ambient temperature ranges corresponding to different working limit temperature values can be specifically represented by Table 1 below.

[0075] Table 1

[0076]

[0077] Through the above steps S1210 to S1212, the higher the preset ambient temperature range is, the higher the working limit temperature value is set. In this way, the balance of the heat dissipation efficiency and power consumption of the heat dissipation device is ensured.

[0078] Step S1300, according to the current temperature difference between the current working limit temperature and the current working temperature, the running state of the heat dissipation device in the heat dissipation object is controlled.

[0079] In the embodiment, the heat dissipation device is built-in in the heat dissipation object, which is used to dissipate heat of the heat dissipation object to reduce the current working temperature of the heat dissipation object.

[0080] In an embodiment of the present application, the specific implementation principle of the above step S1300 can be: in the case of a larger current temperature difference, the running state of the heat dissipation device in the heat dissipation object is controlled to be a running state with higher heat dissipation efficiency. For example, a corresponding relationship between different temperature difference ranges and different heat dissipation device running states is set, wherein the larger the temperature difference range corresponding to the temperature difference is, the higher the heat dissipation efficiency corresponding to the heat dissipation device running state is. It should be noted that as long as the specific implementation manner meets the specific implementation principle, it is within the protection scope of the present application.

[0081] Through the above step S1300, the heat dissipation of the heat dissipation object is completed at the same time, and the current temperature difference is dynamically calculated, thereby realizing reasonable and efficient control of the heat dissipation device.

[0082] Based on the above content, the present application provides a heat dissipation method, which comprises: obtaining the current working temperature of the heat dissipation object and the current ambient temperature of the environment; determining the current working limit temperature of the heat dissipation object according to the current ambient temperature and at least two preset ambient temperature ranges, wherein different preset ambient temperature ranges correspond to different working limit temperature values; and controlling the running state of the heat dissipation device in the heat dissipation object according to the current temperature difference between the current working limit temperature and the current working temperature. In this method, on the one hand, the heat dissipation of the heat dissipation object is completed at the same time, and the current temperature difference is dynamically calculated, thereby realizing reasonable and efficient control of the heat dissipation device. On the other hand, different working limit temperature values are set for different preset ambient temperature ranges, which can realize the balance of the heat dissipation efficiency and power consumption of the heat dissipation device, thereby avoiding a series of problems such as continuous work of the heat dissipation device in the heat dissipation object causing power consumption and the like.

[0083] In another embodiment of the present application, in order to implement the step S1300, the heat dissipation method provided by the present application further comprises the following steps S1310 and S1311 before the step S1300. Figure 2

[0084] In the step S1310, a target environment temperature range is determined according to the current environment temperature and at least two preset environment temperature ranges.

[0085] In the step S1310, a target environment temperature range is determined according to the current environment temperature and at least two preset environment temperature ranges.

[0086] In the step S1311, a heat dissipation device operation strategy corresponding to the target environment temperature range is determined as a target heat dissipation device operation strategy.

[0087] In the step S1310, a target environment temperature range is determined according to the current environment temperature and at least two preset environment temperature ranges.

[0088] On the basis of the steps S1310 and S1311, the step S1300 is implemented through the following steps S1320 and S1330.

[0089] In the step S1320, a heat dissipation device operation mode corresponding to a current temperature difference range in the target heat dissipation device operation strategy is determined as a target heat dissipation device operation mode.

[0090] In the step S1330, the operation state of the heat dissipation device in the heat dissipation object is controlled according to the target heat dissipation device operation mode.

[0091] In the step S1310, a target environment temperature range is determined according to the current environment temperature and at least two preset environment temperature ranges.

[0092] ​In an embodiment of the present application, for each heat dissipation device operation strategy, different heat dissipation device operation modes correspond to different heat dissipation efficiencies, and the higher the temperature difference range represents, the higher the heat dissipation efficiency of the heat dissipation device operation mode corresponding to the temperature difference range. For the same heat dissipation device operation mode in different heat dissipation device operation strategies, the preset environment temperature range representing a high environment temperature corresponds to the temperature difference range corresponding to the heat dissipation device operation mode in the heat dissipation device operation strategy, which is a subset of the temperature difference range corresponding to the heat dissipation device operation mode in the heat dissipation device operation strategy representing a low environment temperature. In this way, for each heat dissipation device operation strategy, the greater the temperature difference, the higher the heat dissipation efficiency of the heat dissipation device, and for the same heat dissipation device operation mode, the higher the environment temperature, the smaller the temperature difference triggering the corresponding heat dissipation device operation mode. In this way, reasonable heat dissipation of the heat dissipation object is achieved.

[0093] For the above, in an embodiment of the present application, the at least two preset environment temperature ranges are a first environment temperature range, a second environment temperature range and a third environment temperature range, each environment temperature in the second environment temperature range is less than each environment temperature in the third environment temperature range and greater than each environment temperature in the first environment temperature range, the heat dissipation device includes a first heat dissipation device and a second heat dissipation device, and the heat dissipation efficiency of the second heat dissipation device is higher than that of the first heat dissipation device. And, the above step S1320 is specifically implemented by the following steps S1321 to S1322.

[0094] Step S1321, in the case that the target environment temperature range is the first environment temperature range, determining the target heat dissipation device operation strategy as: running the first heat dissipation device in the case that the current temperature difference is less than or equal to the first preset temperature difference and greater than 0, running the second heat dissipation device in the case that the current temperature difference is greater than the first preset temperature difference and less than or equal to the second preset temperature difference, running the first heat dissipation device and the second heat dissipation device in the case that the current temperature difference is greater than the second preset temperature difference, and stopping running the first heat dissipation device and the second heat dissipation device in the case that the current temperature difference is equal to 0.

[0095] Step S1322, in the case that the target environment temperature range is the second environment temperature range, determining the target heat dissipation device operation strategy as: running the first heat dissipation device in the case that the current temperature difference is less than or equal to the third preset temperature difference and greater than 0, running the second heat dissipation device in the case that the current temperature difference is greater than the third preset temperature difference and less than or equal to the fourth preset temperature difference, running the first heat dissipation device and the second heat dissipation device in the case that the current temperature difference is greater than the fourth preset temperature difference, and stopping running the first heat dissipation device and the second heat dissipation device in the case that the current temperature difference is equal to 0.

[0096] Wherein, the fourth preset temperature difference is less than the second preset temperature difference, and the third preset temperature difference is less than the first preset temperature difference.

[0097] In step S1323, when the target environment temperature range is the third environment temperature range, the target heat dissipation device operation strategy is determined as follows: running 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, running 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, running 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 stopping running the first heat dissipation device and the second heat dissipation device when the current temperature difference is equal to 0.

[0098] In the above embodiment, 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.

[0099] In an embodiment of the present application, the first heat dissipation device is a micro refrigeration fan, and the second heat dissipation device is a semiconductor refrigeration module. Of course, the first heat dissipation device and the second heat dissipation device can also be other types of heat dissipation modules, such as heat pipes, vapor chambers, etc., as long as the heat dissipation efficiency of the second heat dissipation device is higher than that of the first heat dissipation device, where the heat dissipation efficiency can be measured by the amount of heat dissipated per unit time.

[0100] On the basis of the above, in steps S1321 to S1323, two heat dissipation devices are used to achieve 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.

[0101] In one example, the first preset temperature difference is 12℃, the second preset temperature difference is 18℃, the third preset temperature difference is 10℃, the fourth preset temperature difference is 15℃, the fifth preset temperature difference is 5℃, and the sixth preset temperature difference is 8℃.

[0102] For the above embodiment, let the first preset temperature difference be t1, the second preset temperature difference be t2, the third preset temperature difference be t3, the fourth preset temperature difference be t4, the fifth preset temperature difference be t5, the sixth preset temperature difference be t6, the current working temperature of the heat dissipation object be Tw, and t1 be 12℃, t2 be 18℃, t3 be 10℃, t4 be 15℃, t5 be 5℃, and t6 be 8℃, and the heat dissipation device operation modes be 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 strategy of the heat dissipation device corresponding to different preset environment temperature ranges is shown in Table 2 below.

[0103] Table 2

[0104]

[0105] Based on the above Table 2, it can be seen that the higher the preset ambient temperature range representing the ambient temperature, the smaller the temperature difference of the heat dissipation device triggering the operation of the first heat dissipation device and the second heat dissipation device in the heat dissipation device operation strategy. For example, in the heat dissipation device operation strategy corresponding to the first ambient temperature range, the first heat dissipation device is operated when 0 < Tw-Ta≤t1, while in the heat dissipation device operation condition corresponding to the second ambient temperature range, the first heat dissipation device is operated when 0 < Tw-Ta≤t2, and t2 is less than t1. That is, the temperature difference of the heat dissipation device triggering the operation of the first heat dissipation device and the second heat dissipation device is dynamically adjusted according to the ambient temperature. In addition, under the same preset ambient temperature, the greater the temperature difference, the greater the heat dissipation efficiency of the heat dissipation device. In this way, reasonable heat dissipation of the heat dissipation object can be achieved.

[0106] In combination with the above, for the above step S1330, in one example, when the target ambient temperature range is [20℃, 40℃), if the current temperature difference is 0℃, then the first heat dissipation device and the second heat dissipation device are controlled to stop operating; if the current temperature difference is greater than 0℃ and less than or equal to 12℃, then the first heat dissipation device is controlled to operate; if the current temperature difference is greater than 12℃ and less than or equal to 18℃, then the second heat dissipation device is controlled to operate; and if the current temperature difference is greater than 18℃, then the first heat dissipation device and the second heat dissipation device are controlled to operate.

[0107] In another example, when the target ambient temperature range is [40℃, 60℃), if the current temperature difference is 0℃, then the first heat dissipation device and the second heat dissipation device are controlled to stop operating; if the current temperature difference is greater than 0℃ and less than or equal to 10℃, then the first heat dissipation device is controlled to operate; if the current temperature difference is greater than 10℃ and less than or equal to 15℃, then the second heat dissipation device is controlled to operate; and if the current temperature difference is greater than 15℃, then the first heat dissipation device and the second heat dissipation device are controlled to operate.

[0108] In yet another example, when the target ambient temperature range is [60℃, 80℃), if the current temperature difference is 0℃, then the first heat dissipation device and the second heat dissipation device are controlled to stop operating; if the current temperature difference is greater than 0℃ and less than or equal to 5℃, then the first heat dissipation device is controlled to operate; if the current temperature difference is greater than 5℃ and less than or equal to 8℃, then the second heat dissipation device is controlled to operate; and if the current temperature difference is greater than 8℃, then the first heat dissipation device and the second heat dissipation device are controlled to operate.

[0109] The present application also provides a heat dissipation device 300, as shown in the accompanying drawings, the device 300 comprises: Figure 3 as shown, the device 300 comprises:

[0110] The acquisition module 310 is configured to acquire the current working temperature of the heat dissipation object and the current ambient temperature of the environment;

[0112] 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 temperature difference between the current operating limit temperature and the current operating temperature.

[0113] In the first embodiment of the present application, the determining module 320 is further configured to:
