Description

一种温度控制方法及设备Temperature control method and device 技术领域Technical field
本文涉及但不限于电子领域中的控制技术,尤其涉及一种温度控制方法及设备。This document relates to, but is not limited to, control technology in the field of electronics, and more particularly to a temperature control method and apparatus.
背景技术Background technique
随着电子技术的发展和人们生活水平的提高,终端(尤其是智能终端)的应用也越来越广泛。目前,智能终端基本上都是采用锂离子电池供电的。由于锂离子电池受温度影响很大,因此,锂电池的充电、放电只能在一定的温度范围内进行。举例来说,锂离子电池一般内置有负温度系数(NTC,Negative Temperature Coefficient)热敏电阻,智能终端根据该NTC热敏电阻来判断电池温度,并根据电池温度的大小判断上述锂电子电池是否可以进行充、放电。With the development of electronic technology and the improvement of people's living standards, the application of terminals (especially smart terminals) has become more and more extensive. At present, smart terminals are basically powered by lithium-ion batteries. Since the lithium ion battery is greatly affected by the temperature, the charging and discharging of the lithium battery can only be performed within a certain temperature range. For example, a lithium ion battery generally has a negative temperature coefficient (NTC) thermistor, and the smart terminal determines the battery temperature according to the NTC thermistor, and determines whether the lithium electronic battery can be determined according to the temperature of the battery. Charge and discharge.
然而,智能终端在多种应用场景下被用户使用,当智能终端在温度低的寒冷环境中被使用时,由于外界环境的温度很低,导致了锂离子电池的电池温度也较低,由于锂电子电池的电池温度较低时其活性会不足,因此,即使锂电池的电池电量满格,使用一段时间后就会造成低电关机。甚至电池温度过低时,智能终端的锂离子电池会进入保护状态,无法充放电。强行在电池温度过低时充放电还可能会引发严重事故。However, the smart terminal is used by the user in various application scenarios. When the smart terminal is used in a cold environment with low temperature, the battery temperature of the lithium ion battery is also low due to the low temperature of the external environment, due to lithium. When the battery temperature of the electronic battery is low, its activity will be insufficient. Therefore, even if the battery of the lithium battery is fully charged, it will cause a low power shutdown after a period of use. Even when the battery temperature is too low, the lithium ion battery of the smart terminal will enter the protection state and cannot be charged and discharged. Forcibly charging and discharging when the battery temperature is too low may cause serious accidents.

A temperature control device.
本发明实施例中的温度控制设备1是通过硬件模块和软件模块的结合实现对终端2的电池20所在的环境温度的调节的。 The temperature control device 1 in the embodiment of the present invention implements adjustment of the ambient temperature of the battery 20 of the terminal 2 through a combination of a hardware module and a software module.
如图7所示,本发明实施例提供了一种温度控制设备1,设置在终端2中,该温度控制设备1可以包括:As shown in FIG. 7, the embodiment of the present invention provides a temperature control device 1 which is disposed in the terminal 2. The temperature control device 1 may include:
围绕在所述终端2的电池20四周、形成表征电池20所在的外界环境的第一空间的内壳100和与所述内壳100之间以填充物102填充的外壳101;Surrounding the battery 20 of the terminal 2, forming an inner casing 100 defining a first space in which the battery 20 is located, and a casing 101 filled with the filler 102 between the inner casing 100;
温度传感器110,所述温度传感器110设置在所述填充物102中;a temperature sensor 110, the temperature sensor 110 is disposed in the filler 102;

制热装置120,所述制热装置120设置在所述填充物102中;a heating device 120, the heating device 120 is disposed in the filler 102;
与所述制热装置120连接的升温控制装置121,所述升温控制装置121与所述控制芯片21连接。The temperature increase control device 121 connected to the heating device 120 is connected to the control chip 21.
具体的,结合图8可知,通过密闭在所述外壳101和所述内壳100之间的所述填充物102获取所述第一热量,并通过所述填充物102提高所述第一空间的当前温度。以及,通过软件模块当所述第一空间中的当前温度低于预设阈值时,启动升温控制装置121,这样,该升温控制装置121就可以根据第一空间的当前温度通过制热装置120控制第一热量的产生,从而将该第一热量传输至填充物102,从而使得第一空间的温度保持在合理的温度范围内,保证处于该第一空间内的电池20的正常充放电的温度环境。Specifically, as can be seen from FIG. 8 , the first heat is obtained by the filler 102 sealed between the outer casing 101 and the inner casing 100, and the first space is raised by the filler 102. Current Temperature. And, when the current temperature in the first space is lower than a preset threshold by the software module, the temperature increase control device 121 is activated, so that the temperature increase control device 121 can be controlled by the heating device 120 according to the current temperature of the first space. The first heat is generated, thereby transferring the first heat to the filler 102, so that the temperature of the first space is maintained within a reasonable temperature range, and the normal charging and discharging temperature environment of the battery 20 in the first space is ensured. .
需要说明的是,本发明实施例提供的温度控制设备1是在电池20所在的环境温度较低,以至于不能正常充放电的情况下,对电池20所在的环境温度进行提高的。通过外壳101、内壳100和填充物102设置在电池20的四周,形成一个电池20所在的第一空间,该第一空间为封闭的空间。在本发明实施例中,升温控制装置121通过制热装置120提高第一空间的温度就能实现对电池20的环境温度的提高。It should be noted that the temperature control device 1 provided by the embodiment of the present invention improves the ambient temperature of the battery 20 when the ambient temperature of the battery 20 is low, so that the battery 20 cannot be normally charged and discharged. The outer casing 101, the inner casing 100 and the filler 102 are disposed around the battery 20 to form a first space in which the battery 20 is located, the first space being a closed space. In the embodiment of the present invention, the temperature increase control device 121 can increase the ambient temperature of the battery 20 by increasing the temperature of the first space by the heating device 120.
可选的,由于第一空间的温度是可以受到升温控制装置121和外界环境的影响的,因此,第一空间的温度是可以变化的,故温度检测电路111通过温度传感器110每次采集的都是第一空间的当前温度。Optionally, since the temperature of the first space is affected by the temperature rising control device 121 and the external environment, the temperature of the first space may be changed, so the temperature detecting circuit 111 collects each time through the temperature sensor 110. Is the current temperature of the first space.
可选地,温度检测电路111和升温控制装置121的具体的结构将在后面的实施例中进行详细地说明。 Alternatively, the specific configuration of the temperature detecting circuit 111 and the temperature rising control device 121 will be described in detail in the following embodiments.
需要说明的是,将电池20围绕,并形成第一空间的器件是由包裹电池20的壳体,该壳体由内壳100、外壳101以及内外壳之间填充的填充物102组成。It should be noted that the device that surrounds the battery 20 and forms the first space is composed of a casing that encloses the battery 20, and the casing is composed of a filler 102 filled between the inner casing 100, the outer casing 101, and the inner casing.
可选的,内壳100与外壳101围绕形成的第一空间的空间较小。Optionally, the inner casing 100 and the outer casing 101 have a small space around the first space formed.
可选的,本发明实施例中的填充物102使用高比热容的材料来隔绝外界的温度对电池20的影响,可选的,本发明实施例中的填充物102可以为空气、水或油等介质。Optionally, the filler 102 in the embodiment of the present invention uses a material with a high specific heat capacity to isolate the influence of the external temperature on the battery 20. Alternatively, the filler 102 in the embodiment of the present invention may be air, water, or oil. medium.
可以理解的是,当上述填充物102为空气、水或油等介质时,将第一空间当做电池20的周围环境,因此,填充物的温度就是电池20的环境温度,即第一空间的温度。It can be understood that when the filler 102 is a medium such as air, water or oil, the first space is regarded as the surrounding environment of the battery 20. Therefore, the temperature of the filler is the ambient temperature of the battery 20, that is, the temperature of the first space. .
可选的,外壳101使用耐冲击的坚实材料,如金属铝,用于保护电池。内壳100使用延展性良好的柔性材料,如ABS(Acrylonitrile Butadiene Styrene)树脂,其耐热性好,抗冲击能力强。除去电路接口部分,上述内壳100和外壳101要密封良好,这样才能使填充的两者之间的填充物102无法流出或逸出。Alternatively, the outer casing 101 uses a strong impact resistant material, such as metal aluminum, to protect the battery. The inner casing 100 uses a flexible material having good ductility, such as ABS (Acrylonitrile Butadiene Styrene) resin, which has good heat resistance and strong impact resistance. In addition to the circuit interface portion, the inner casing 100 and the outer casing 101 are preferably sealed so that the filler 102 between the two cannot flow out or escape.
可选的,制热装置120传输第一热量给填充物102,这样,填充物102的温度升高了,也就是第一空间的当前温度升高了。Alternatively, the heating device 120 transmits the first heat to the filler 102 such that the temperature of the filler 102 rises, that is, the current temperature of the first space increases.
可以理解的是,围绕电池20的壳体一方面在电池20与外界环境之间形成了热量的缓冲,使电池20的温度不至于受外界温度影响过快;另一方面由于内壳100及外壳101之间的空间(第一空间)较小,使得提升填充物102的温度较为容易。It can be understood that the casing surrounding the battery 20 forms a buffer of heat between the battery 20 and the external environment on the one hand, so that the temperature of the battery 20 is not affected too much by the external temperature; on the other hand, the inner casing 100 and the outer casing The space between the 101 (the first space) is small, making it easier to raise the temperature of the filler 102.
需要说明的是,本发明实施例中的填充物102的作用可由同等作用的其他结构来代替,本发明实施例不作限制。It should be noted that the function of the filler 102 in the embodiment of the present invention may be replaced by other structures having the same function, which is not limited in the embodiment of the present invention.
可选的,通过所述温度传感器110感应所述填充物102的温度,得到第一模拟量,以及通过所述温度检测电路111将所述第一模拟量转化为第一数字量,最后通过所述控制芯片21获取与所述第一数字量对应的第一温度,所述第一温度为所述第一空间的当前温度。Optionally, the temperature of the filler 102 is sensed by the temperature sensor 110 to obtain a first analog quantity, and the first analog quantity is converted into a first digital quantity by the temperature detecting circuit 111, and finally The control chip 21 acquires a first temperature corresponding to the first digital quantity, and the first temperature is a current temperature of the first space.
需要说明的是,由于温度传感器110设置于填充物102中,因此,当填 充物102的温度变化时,温度传感器110产生的第一模拟量会发生改变。温度检测电路检测111到温度传感器的第一模拟量变化,并将其转化为第一数字量,最后输出该第一数字量给控制芯片21。由于控制芯片21内置有第一数字量与温度对照表,于是,通过第一数字量与温度对照表,即可获得该第一数字量对应的电池20周围环境的温度,即第一空间的当前温度了。It should be noted that since the temperature sensor 110 is disposed in the filler 102, when filling When the temperature of the charge 102 changes, the first analog quantity produced by the temperature sensor 110 changes. The temperature detecting circuit detects 111 the first analog quantity change to the temperature sensor and converts it into a first digital quantity, and finally outputs the first digital quantity to the control chip 21. Since the control chip 21 has a first digital quantity and temperature comparison table built therein, the temperature of the environment surrounding the battery 20 corresponding to the first digital quantity, that is, the current state of the first space, can be obtained by using the first digital quantity and the temperature comparison table. The temperature is gone.
可选的,温度传感器110可以使用NTC热敏电阻,当填充物102温度下降时,NTC热敏电阻的阻值就会上升;也可以使用热电偶等其他温度传感器。Alternatively, the temperature sensor 110 can use an NTC thermistor. When the temperature of the filler 102 drops, the resistance of the NTC thermistor rises; other temperature sensors such as thermocouples can also be used.
需要说明的是,当温度传感器110为NTC热敏电阻时,当填充物102的温度变化时,温度传感器110(NTC热敏电阻)的对应电阻模拟量会发生改变。温度检测电路检测111到温度传感器的电阻模拟量变化,并将其先转化为电压模拟量,而温度检测电路111的模数转换器1111再将电压模拟量转化为电压数字量,最后该电压数字量输入给控制芯片21。由于控制芯片21内置有电压与温度对照表,于是,通过电压与温度对照表,即可获得该电压数字量对应的电池20周围环境的温度,即第一空间的当前温度。It should be noted that when the temperature sensor 110 is an NTC thermistor, when the temperature of the filler 102 changes, the corresponding resistance analog quantity of the temperature sensor 110 (NTC thermistor) changes. The temperature detecting circuit detects 111 a change in the resistance analog quantity of the temperature sensor and converts it into a voltage analog quantity first, and the analog-to-digital converter 1111 of the temperature detecting circuit 111 converts the voltage analog quantity into a voltage digital quantity, and finally the voltage number The amount is input to the control chip 21. Since the control chip 21 has a built-in voltage and temperature comparison table, the temperature of the environment around the battery 20 corresponding to the voltage digital quantity, that is, the current temperature of the first space, can be obtained by the voltage and temperature comparison table.
可选的,本发明实施例还可以使用电池电芯温度,通过实验和算法将电池电芯温度转换为电池周围环境的温度来实现第一空间的当前温度的采集。Optionally, the embodiment of the present invention can also use the battery cell temperature to convert the battery cell temperature into the temperature of the surrounding environment of the battery through experiments and algorithms to achieve the current temperature collection in the first space.
需要说明的是,本发明实施例是通过所述控制芯片21控制所述升温控制装置121,以及通过所述升温控制装置121控制所述制热装置120是否产生所述第一热量。It should be noted that, in the embodiment of the present invention, the temperature increase control device 121 is controlled by the control chip 21, and whether the first heat is generated by the heating device 120 is controlled by the temperature increase control device 121.
需要说明的是,升温控制装置121为控制热装置120产生第一热量的开关。只要可以实现根据第一空间的当前温度控制第一热量的传输开关的形式的结构都可以。It should be noted that the temperature increase control device 121 is a switch that controls the heat device 120 to generate the first heat. As long as a structure in the form of a transfer switch that controls the first heat according to the current temperature of the first space can be realized.
示例性的,由于终端2(例如,智能终端)工作时,终端2的控制芯片20会产生大量的热量可以视为第一热量,因此,制热装置120可以使用流经发热的芯片(如,控制芯片120)和填充物102的循环水管或油管来实现。当电池20处于低温环境时,通过软件模块(控制芯片21)的作用使芯片发热,而循环的水管或油管在芯片一侧受热后,根据流体的对流热传导作用,水或油会将第一热量传递到填充物102侧,从而达到提升电池20周围环境的温度(第一空间的当前温度)的目的。当第一空间的当前温度达到一定温度 后,就停止芯片发热。为了避免环境温度(第一空间的当前温度)较高时,热导管仍然把第一热量从工作时的芯片处传递到填充物102中。因此,通过热导管上安装一个阀门,当电池20周围环境的温度较高时,升温控制装置121关闭阀门,此时,第一热量就不会从发热芯片处导往填充物102中。上述阀门可以使用电机控制,阀门一般是打开的,当电机通电后就可以关闭阀门。Exemplarily, since the terminal 2 (for example, the smart terminal) operates, the control chip 20 of the terminal 2 generates a large amount of heat, which can be regarded as the first heat. Therefore, the heating device 120 can use a chip that flows through the heat (for example, The control chip 120) and the circulating water pipe or oil pipe of the filler 102 are realized. When the battery 20 is in a low temperature environment, the chip is heated by the function of the software module (control chip 21), and after the circulating water pipe or the oil pipe is heated on one side of the chip, the water or the oil will be the first heat according to the convective heat conduction of the fluid. It is transferred to the side of the filler 102 to achieve the purpose of raising the temperature of the environment around the battery 20 (the current temperature of the first space). When the current temperature of the first space reaches a certain temperature After that, the chip is stopped from heating. In order to avoid a higher ambient temperature (the current temperature of the first space), the heat pipe still transfers the first heat from the chip at the time of operation to the filler 102. Therefore, by installing a valve on the heat pipe, when the temperature of the environment around the battery 20 is high, the temperature rise control device 121 closes the valve, and at this time, the first heat is not conducted from the heat generating chip into the filler 102. The above valves can be controlled by a motor, the valves are normally open, and the valves can be closed when the motor is energized.

As can be seen from FIG. 9, an RT (NTC thermistor) is a temperature sensor 110, and the NTC thermistor and R1 (first resistor 11100), R2 (second resistor 11101), and R3 (third resistor 11102) together form a Wythe. Power on bridge 1110. When R1, R2, and R3 select appropriate resistance values, the change in RT resistance (first analog quantity) can be converted into a suitable voltage change, and this voltage change is converted into a voltage digital quantity by the ADC analog-to-digital converter 1111 ( The first digital quantity is finally output to the control chip 21 by the digital quantity.
