TECHNICAL FIELD

[0001] The present application relates to the field of charging equipment, in particular to a constant temperature device and constant temperature control method for charging equipment. BACKGROUND

[0002] The charging equipment can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.), and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is provided with a charging plug for charging electric vehicles.

[0003] The circuit board is provided inside the charging equipment, and electronic components are provided on the circuit board. The electronic components inside the charging equipment are generally in the shell, but the internal electronic components will generate heat during operation, which will cause the internal environment to overheat. Heat dissipation auxiliary components are added.

[0004] However, the working efficiency of some electronic components is better in a higher constant temperature. In the present application, the part of electronic components is defined as high-temperature electronic components, and the constant temperature refers to a certain temperature range. Therefore, the part of electronic components needs to be installed separately to reduce the probability of damage to other components. Therefore, a constant temperature device for charging equipment is proposed. SUMMARY

[0005] In order to ensure the working efficiency of high-temperature electronic components while reducing the probability of damage to other components, the present application provides a constant temperature device and constant temperature control method for charging equipment.

[0006] In a first aspect, the present application provides a constant temperature device for charging equipment, which adopts the following technical solution:

[0007] A constant temperature device for charging equipment, comprising a circuit board, a first component provided on the circuit board, a heat dissipation assembly provided on the circuit board, a mounting surface provided on the heat dissipation assembly and perpendicular to the circuit board, and a high-temperature electronic component provided on the mounting surface, characterized in that the heat dissipation assembly is provided with a heat dissipation auxiliary assembly, the heat dissipation assembly comprises a plurality of heat dissipation fins stacked, a ventilation duct is formed between adjacent heat dissipation fins, a cover box is provided on the mounting surface and covers all high-temperature electronic components on the mounting surface, and a temperature sensor is provided on the mounting surface and located in the cover box.

[0008] By adopting the technical scheme, in the use process of the charging device, the high-temperature electronic components on the mounting surface emit a large amount of heat, the heat dissipation assembly can accelerate the heat dissipation inside the charging device, and the temperature sensor can acquire the temperature inside the cover box in real time. If the temperature inside the cover box does not reach the temperature at which the working efficiency of the high-temperature electronic components is relatively high, the heat dissipation auxiliary assembly does not work, and the temperature inside the cover box continues to rise. When the temperature inside the cover box reaches the temperature range at which the working efficiency of the high-temperature electronic components is relatively high, the heat dissipation auxiliary assembly starts to work to accelerate the heat dissipation efficiency of the heat dissipation assembly. In this way, the temperature inside the cover box is kept in the temperature range at which the working efficiency of the high-temperature electronic components is relatively high, and the temperature inside the cover box will not damage the first components outside the cover box, thereby realizing the working efficiency of the high-temperature electronic components while reducing the probability of damaging other components.

[0009] Optionally, the heat dissipation auxiliary assembly comprises fans respectively arranged on both ends of the heat dissipation assembly, and the fans are detachably mounted on the heat dissipation assembly.

[0010] By adopting the technical scheme, the fans arranged can accelerate the air flow in the ventilation pipeline, thereby realizing the heat dissipation efficiency of the heat dissipation assembly.

[0011] Optionally, the temperature sensor is arranged in multiple numbers at intervals on the mounting surface.

[0012] By adopting the technical scheme, the temperature sensor is arranged in multiple numbers on the mounting surface. When acquiring the temperature inside the cover box, the temperature of multiple positions can be comprehensively judged, and the acquired temperature data is more accurate.

[0013] Optionally, a heat insulation layer is arranged on the outer layer of the cover box.

[0014] By adopting the technical scheme, the heat insulation layer arranged can block the heat exchange between the inside and outside of the cover box during the working of the high-temperature electronic components, thereby ensuring that the temperature outside the cover box remains low.

[0015] Optionally, a fixing piece is arranged on the mounting surface, and the fixing piece is provided with a threaded hole penetrating through the fixing piece. The fan is provided with a through hole aligned with the threaded hole, and the fan is provided with a fixing bolt with one end penetrating through the through hole and being threadedly connected to the threaded hole.

[0016] By adopting the technical scheme, when the fan is installed, the through hole on the fan is aligned with the threaded hole, and the fixing bolt is screwed in the threaded hole through the through hole, thereby realizing the installation of the fan. When the fixing bolt is removed, the fan can be detached.

[0017] Optionally, the cover box is provided with a mounting edge near the mounting surface, and the mounting surface is provided with a mounting ring groove for embedding the mounting edge.

[0018] In a second aspect, the application provides a constant temperature control method for a charging device, which adopts the following technical scheme:

[0022] Corresponding minimum temperature data are acquired based on the temperature interval data;

[0023] The real-time temperature data are compared with the minimum temperature data, and if the real-time temperature data are greater than the minimum temperature data, the heat dissipation auxiliary component is controlled to work; otherwise, the heat dissipation auxiliary component does not work.

[0024] By adopting the above technical scheme, in the working process of the charging device, the system acquires real-time temperature data inside the cover box in real time, compares the temperature interval data with the minimum temperature data, and if the real-time temperature data are greater than the minimum temperature data, it indicates that the temperature inside the cover box is suitable for the working of the high-temperature electronic components, but the high-temperature electronic components will continuously heat, so the heat dissipation auxiliary component is controlled to work, thereby preventing the temperature inside the cover box from being in the temperature interval data, so that the overall working efficiency of the high-temperature electronic components is improved in the working process.

[0025] Optionally, the following steps are further performed during the working of the heat dissipation auxiliary component:

[0026] Working duration data of the high-temperature electronic components are acquired;

[0027] The working duration of the high-temperature electronic components is regionally divided to acquire a plurality of time interval data sets, wherein the optimal temperature data of the high-temperature electronic components are different in different time interval data sets;

[0030] The real-time temperature data are compared with the optimal temperature data, and the power of the heat dissipation auxiliary component is adjusted.

[0031] By adopting the technical scheme, since the optimal temperature data corresponding to the high-temperature electronic component fluctuates with the different working duration of the high-temperature electronic component, the target duration area data can be determined, and the real-time temperature data is compared with the optimal temperature data, and the power of the heat dissipation auxiliary component is adjusted, so that the target of adjusting the temperature inside the cover box is achieved, thereby ensuring the working efficiency of the high-temperature electronic component.

[0032] Optionally, in the process of comparing the real-time temperature data with the optimal temperature data, the following steps are performed:

[0033] If the real-time temperature data is greater than the optimal temperature data, the power of the heat dissipation auxiliary component is controlled to be increased; and if the real-time temperature data is less than the optimal temperature data, the power of the heat dissipation auxiliary component is controlled to be decreased.

[0034] By adopting the technical scheme, when the real-time temperature data is greater than the optimal temperature data, it indicates that the temperature inside the cover box is too high, and the power of the heat dissipation auxiliary component is controlled to be increased, so that the heat dissipation inside the cover box is accelerated, and the temperature inside the cover box tends to the optimal temperature data; and if the real-time temperature data is less than the optimal temperature data, it indicates that the temperature inside the cover box is too low, and the power of the heat dissipation auxiliary component is controlled to be decreased, so that the heat dissipation inside the cover box is slowed down, and in the case that the high-temperature electronic component continuously works and generates heat, the temperature inside the cover box tends to the optimal temperature data.

[0035] Optionally, in the process of obtaining the working duration data of the high-temperature electronic component, the following steps are included:

[0036] Based on the operation that the high-temperature electronic component stops working, the heat dissipation auxiliary component is controlled to be turned on to the maximum power;

[0037] The real-time temperature data is compared with external temperature data outside the cover box;

[0038] Based on the real-time temperature data being equal to the external temperature data, the heat dissipation auxiliary component is controlled to stop working.

[0039] By adopting the technical scheme, by controlling the heat dissipation auxiliary component to be turned on to the maximum power, the temperature inside the cover box can be lowered.

[0040] In summary, the present application includes at least one of the following beneficial technical effects:

[0041] In the use process of the charging device, the high-temperature electronic components on the mounting surface emit a large amount of heat, the heat dissipation assembly can accelerate the heat dissipation inside the charging device, and the temperature sensor can obtain the temperature inside the cover box in real time. If the temperature inside the cover box does not reach the temperature at which the high-temperature electronic components have a higher working efficiency, the heat dissipation auxiliary assembly does not work at this time, and the temperature inside the cover box continues to rise. When the temperature inside the cover box reaches the temperature range at which the high-temperature electronic components have a higher working efficiency, the heat dissipation auxiliary assembly starts to work to accelerate the heat dissipation efficiency of the heat dissipation assembly, so that the temperature inside the cover box is maintained in the temperature range at which the high-temperature electronic components have a higher working efficiency, and the temperature inside the cover box will not damage the first component outside the cover box, thereby realizing the guarantee of the working efficiency of the high-temperature electronic components while reducing the probability of damage to other components.

[0042] The air flow in the ventilation duct can be accelerated, so that the heat dissipation efficiency of the heat dissipation assembly can be accelerated.

DETAILED DESCRIPTION

[0051] The following is a further detailed description of the present application.

[0052] In a first aspect, the embodiments of the present application disclose a constant temperature device for a charging device, which refers to Figure 1 and Figure 2 , comprising a circuit board 1, a first component 2 mounted on the circuit board 1, a heat dissipation assembly mounted on the circuit board 1, a mounting surface 3 arranged on the heat dissipation assembly and perpendicular to the circuit board 1, and a high-temperature electronic component 4 arranged on the mounting surface 3; in the embodiments of the present application, the first component 2 refers to an electronic component that is easy to be damaged in a high-temperature environment, and the high-temperature electronic component 4 refers to an electronic component that has a higher working efficiency in a certain high-temperature region.

[0053] Referring to Figure 2 and Figure 3 , in addition, a heat dissipation auxiliary assembly is mounted on the heat dissipation assembly; in the embodiments of the present application, the heat dissipation assembly comprises a plurality of heat dissipation fins 5 arranged in layers, and a ventilation duct 6 is formed between adjacent heat dissipation fins 5, which is used for air flow in the heat dissipation assembly, so as to improve the heat dissipation efficiency of the heat dissipation assembly; in order to ensure that the region where the high-temperature electronic component 4 is located is in a temperature range with a higher working efficiency, a cover box 7 is mounted on the mounting surface 3 and covers all the high-temperature electronic components 4 on the mounting surface 3; in addition, a temperature sensor 8 is arranged on the mounting surface 3 and located in the cover box 7; since the space in the cover box 7 is large, in order to make the obtained temperature data more accurate and reduce errors, the temperature sensor 8 is mounted on the mounting surface 3 in multiple positions.

[0054] In order to further isolate the space inside the cover box 7 from the space outside the cover box 7, a heat insulation layer (not shown in the figure) is arranged on the outer layer of the cover box 7; in the embodiments of the present application, the heat insulation layer uses silicide heat insulation cotton as a raw material.

[0055] Referring to Figure 2 and Figure 3 , in order to accelerate the heat dissipation of the heat dissipation assembly when the temperature inside the cover box 7 is too high, in the embodiments of the present application, the heat dissipation auxiliary assembly comprises a fan 9 mounted on both ends of the heat dissipation assembly, and the fan 9 is detachably mounted on the heat dissipation assembly; in order to facilitate the mounting and dismounting of the fan 9, a fixing sheet 10 is arranged on the mounting surface 3, and a threaded hole 11 is formed through the fixing sheet 10, a through hole 12 aligned with the threaded hole 11 is formed on the fan 9, a fixing bolt 13 is arranged on the fan 9, one end of the fixing bolt 13 passes through the through hole 12 and is screwed in the threaded hole 11; when the fan 9 needs to be mounted, the through hole 12 on the fan 9 is aligned with the threaded hole 11, and then the fixing bolt 13 is screwed in the threaded hole 11 through the through hole 12, so that the fan 9 can be mounted; and when the fan 9 needs to be dismounted, the fixing bolt 13 is removed, so that the fan 9 can be dismounted.

[0056] It is pointed out here that one of the fans 9 is used as a supply fan 9, and the other fan 9 is used as an exhaust fan 9; the air flow in the ventilation duct 6 can be accelerated to achieve the effect of accelerating the heat dissipation efficiency of the heat dissipation group.

[0057] Referring to Figure 2 and Figure 3 In addition, in the present embodiment, the cover box 7 is detachably mounted on the mounting surface 3, and a mounting edge 14 is integrally formed on the side of the cover box 7 close to the mounting surface 3, and a mounting ring groove 15 is provided on the mounting surface 3 for embedding the mounting edge 14, and a reinforcing pattern (not shown in the figure) is integrally formed on the side wall of the mounting edge 14.

[0058] When the cover box 7 is mounted, the mounting edge 14 is directly embedded in the mounting ring groove 15, so that the cover box 7 can be mounted, which is convenient for installation and disassembly, and can be directly pulled out. In addition, through the setting of the reinforcing pattern, the friction between the mounting edge 14 and the inner wall of the mounting ring groove 15 can be increased, thereby increasing the firmness of the cover box 7 during use.

[0059] The implementation principle of the control method for the charging device according to the present embodiment is as follows: In the use process of the charging device, the high-temperature electronic components 4 on the mounting surface 3 emit a large amount of heat, and the heat dissipation group can accelerate the heat dissipation inside the charging device, and the temperature sensor 8 can obtain the temperature inside the cover box 7 in real time. If the temperature inside the cover box 7 does not reach the temperature at which the high-temperature electronic components 4 have a higher working efficiency, the supply fan 9 and the exhaust fan 9 do not work at this time, and as the temperature inside the cover box 7 continues to rise, when the temperature inside the cover box 7 reaches the temperature range at which the high-temperature electronic components 4 have a higher working efficiency, the supply fan 9 and the exhaust fan 9 start to work at this time, which can accelerate the heat dissipation efficiency of the heat dissipation group, so that the temperature inside the cover box 7 is maintained within the temperature range at which the high-temperature electronic components 4 have a higher working efficiency. Since the temperature inside and outside the cover box 7 will not damage the first components 2 outside the cover box 7, the working efficiency of the high-temperature electronic components 4 can be ensured, and the probability of damage to other components can be reduced.

[0060] In a second aspect, the present embodiment discloses a constant temperature control method for a charging device, referring to Figure 4 , comprising the following steps:

[0061] S1, obtaining real-time temperature data inside the cover box 7 in real time;

[0062] Since the high-temperature electronic components 4 continue to work, the temperature inside the cover box 7 rises with the working of the high-temperature electronic components 4.

[0063] S2, retrieving the temperature range data at which the high-temperature electronic components 4 have a higher working efficiency.

[0064] S3, obtaining the lowest temperature data corresponding to the temperature interval data based on the temperature interval data;

[0065] The lowest temperature data is the lowest temperature of the temperature interval corresponding to the temperature interval data.

[0066] S4, comparing the real-time temperature data with the lowest temperature data. If the real-time temperature data is greater than the lowest temperature data, it indicates that the temperature inside the cover box 7 has reached the temperature interval, and the temperature inside the cover box 7 will continue to rise as the high-temperature electronic components 4 continue to work. In order to keep the temperature inside the cover box 7 within the temperature interval data, the system controls the operation of the heat dissipation auxiliary assembly. In the present application, the heat dissipation auxiliary assembly is a blower 9 and an exhaust fan 9, which accelerates the air flow in the pipeline to improve the heat dissipation efficiency; otherwise, it indicates that the cover box 7 needs to be heated continuously, and the heat dissipation auxiliary assembly does not work.

[0067] Through the steps of S1 to S4, the temperature interval data is compared with the lowest temperature data. If the real-time temperature data is greater than the lowest temperature data, it indicates that the temperature inside the cover box 7 is suitable for the work of the high-temperature electronic components 4, but the high-temperature electronic components 4 will continue to heat up, and the heat dissipation auxiliary assembly is controlled to work to prevent the temperature inside the cover box 7 from being within the temperature interval data, so that the overall working efficiency of the high-temperature electronic components 4 is improved during the working process.

[0068] In addition, during the operation of the heat dissipation auxiliary assembly, due to the different working time lengths of the high-temperature electronic components 4, the corresponding optimal temperature data of the high-temperature electronic components 4 will fluctuate, referring to Figure 5 Therefore, the following steps are performed:

[0069] S41, obtaining the working time length data of the high-temperature electronic components 4;

[0070] The working time length data is the time length from the start of the high-temperature electronic components 4 to the current time point.

[0071] S42, dividing the working time length of the high-temperature electronic components 4 into regions and obtaining a plurality of time length region data sets;

[0072] The optimal temperature data of the high-temperature electronic components 4 is different in different time length region data.

[0073] S43, matching the corresponding target time length region data based on the working time length data.

[0074] S44, obtaining the optimal temperature data corresponding to the target working time length data.

[0075] The optimal temperature data is the temperature at which the high-temperature electronic components 4 have the highest working efficiency in the working time length region.

[0076] S45, comparing the real-time temperature data with the optimal temperature data, and adjusting the power of the heat dissipation auxiliary component.

[0077] By comparing the real-time temperature data with the optimal temperature data, and adjusting the power of the heat dissipation auxiliary component, the target of adjusting the temperature inside the cover box 7 is achieved, so as to ensure the working efficiency of the high-temperature electronic component 4.

[0078] In the embodiment of the present application, the specific process of comparing the real-time temperature data with the optimal temperature data is as follows:

[0079] If the real-time temperature data is greater than the optimal temperature data, the power of the heat dissipation auxiliary component is increased; if the real-time temperature data is less than the optimal temperature data, the power of the heat dissipation auxiliary component is decreased.

[0080] And in the process of obtaining the working time data of the high-temperature electronic component 4, the following steps are also performed:

[0081] S411, based on the operation of stopping the high-temperature electronic component 4, that is, when the high-temperature electronic component 4 in the cover box 7 is powered off and stops working.

[0082] S412, control the heat dissipation auxiliary component to start working at the maximum power;

[0083] After the high-temperature electronic component 4 is powered off, the temperature inside the cover box 7 is high at this time, and by starting the heat dissipation auxiliary component to work at the maximum power, the temperature inside the cover box 7 can be maximized to drop.

[0084] S413, comparing the real-time temperature data with the external temperature data outside the cover box 7, based on the real-time temperature data being equal to the external temperature data, it indicates that the temperature inside the cover box 7 has dropped to the normal temperature, at this time, the heat dissipation auxiliary component is controlled to stop working.

[0085] The implementation principle of the constant temperature control method for the charging device is as follows: in the working process of the charging device, the system obtains real-time temperature data in the cover box 7 by real-time acquisition, compares the temperature interval data with the minimum temperature data, and if the real-time temperature data is greater than the minimum temperature data, it indicates that the temperature in the cover box 7 at this time is suitable for the working of the high-temperature electronic component 4, but the high-temperature electronic component 4 will continue to heat, and then the heat dissipation auxiliary assembly is controlled to work; and the system simultaneously obtains the working time length data of the high-temperature electronic component 4, obtains a plurality of time length region data sets, then matches the corresponding target time length region data based on the working time length data, after obtaining the optimal temperature data corresponding to the target working time length data, compares the real-time temperature data with the optimal temperature data, if the real-time temperature data is greater than the optimal temperature data, the power of the heat dissipation auxiliary assembly is controlled to be increased; and if the real-time temperature data is less than the optimal temperature data, the power of the heat dissipation auxiliary assembly is controlled to be reduced.

[0086] In the above process, when the temperature in the cover box 7 changes, the temperature in the cover box 7 can be regulated in time, so as to ensure the working efficiency of the high-temperature electronic component 4.

[0087] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
