具体实施方式Detailed ways
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。The embodiments of the present disclosure are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative, and are not intended to be construed as limiting.
下面参考图1和图6详细描述一下根据本公开实施例的电池热管理***，该电池热 管理***可以控制电池装置10的工作温度，从而可以使得电池装置10充放电性能较好。A battery thermal management system according to an embodiment of the present disclosure, which can control the operating temperature of the battery device 10, can thereby make the battery device 10 better in charge and discharge performance, with reference to FIGS. 1 and 6.
如图1所示，电池热管理***可以包括：风机20、PTC(Positive Temperature Coefficient-正的温度系数)加热器30、电池冷却空调40、吸风机50、电池装置10和多个电子阀60，其中，风机20向PTC加热器30吹风，从而可以经过PTC加热器30后的风为热风，电池冷却空调40可以送出冷风，吸风机50和PTC加热器30之间设置有第一电子阀61，电池冷却空调40和吸风机50之间设置有第二电子阀62。这样电池热管理***通过吸风机50可以选择性地向电池装置10供入热风或冷风。具体地，电池装置10温度高于预定工作温度范围时，电池冷却空调40工作；电池装置10温度低于预定工作温度范围时，风机20和PTC加热器30工作。As shown in FIG. 1, the battery thermal management system may include a fan 20, a PTC (Positive Temperature Coefficient) heater 30, a battery cooling air conditioner 40, a suction fan 50, a battery device 10, and a plurality of electronic valves 60. The fan 20 blows the PTC heater 30 so that the wind that can pass through the PTC heater 30 is hot air, the battery cooling air conditioner 40 can send cold air, and the first electronic valve 61 is disposed between the suction fan 50 and the PTC heater 30. A second electronic valve 62 is disposed between the battery cooling air conditioner 40 and the suction fan 50. Thus, the battery thermal management system can selectively supply hot or cold air to the battery unit 10 through the suction fan 50. Specifically, when the temperature of the battery device 10 is higher than the predetermined operating temperature range, the battery cooling air conditioner 40 operates; when the temperature of the battery device 10 is lower than the predetermined operating temperature range, the fan 20 and the PTC heater 30 operate.
进入电池装置10内的气体介质可以有效改变电池装置10的温度。其中，气体介质可以为冷风或者热风。这样电池热管理***既可实现电池装置10的冷却，也可实现电池装置10的加热，功能更强大。The gaseous medium entering the battery unit 10 can effectively change the temperature of the battery unit 10. Among them, the gaseous medium can be cold air or hot air. Thus, the battery thermal management system can achieve both the cooling of the battery device 10 and the heating of the battery device 10, and the function is more powerful.
图1中方案热换热风道属于内部循环，图1中冷却开启时，换热风道循环方向为：电池冷却空调40——第二电子阀62——吸风机50——电池装置10——电池冷却空调40，换热风道封闭循环。The heat exchange air passage of the scheme in Fig. 1 belongs to the internal circulation. When the cooling is turned on in Fig. 1, the circulation direction of the heat exchange air passage is: battery cooling air conditioner 40 - second electronic valve 62 - suction fan 50 - battery device 10 - - The battery cools the air conditioner 40, and the heat exchange air duct is closed.
图6中所示方案换热风道为不封闭循环。例如图6中冷却开启时，换热风道的循环方向为：电池冷却空调40——第二电子阀62——吸风机50——电池装置10——外部环境。The heat exchange duct shown in Figure 6 is an unclosed cycle. For example, when the cooling is turned on in FIG. 6, the circulation direction of the heat exchange air passage is: battery cooling air conditioner 40 - second electronic valve 62 - suction fan 50 - battery device 10 - external environment.
以电池冷却为例，如果流经电池装置10后的气体介质的温度比外界环境温度低，则采用图1方案比较节能，可以将换热风道中流过电池装置10之后的风回收循环，减少热管理***能耗。如果流经电池装置10后的气体介质的温度比外界环境温度高，则采用图6所示方案比较节能，可以将换热风道中流过电池装置之后的风直接排出外部环境，空调***再吸入温度较低的外部环境空气，进行冷却。Taking the battery cooling as an example, if the temperature of the gaseous medium flowing through the battery device 10 is lower than the ambient temperature, the energy saving method of FIG. 1 is adopted, and the air recovery cycle after flowing through the battery device 10 in the heat exchange air passage can be reduced. Thermal management system energy consumption. If the temperature of the gaseous medium flowing through the battery device 10 is higher than the ambient temperature, the solution shown in FIG. 6 is relatively energy-saving, and the wind flowing through the battery device in the heat exchange air channel can be directly discharged to the external environment, and the air conditioning system is inhaled again. The lower ambient air is cooled.
下面结合图2-图5详细描述根据本公开实施例的电池装置10。A battery device 10 according to an embodiment of the present disclosure will be described in detail below with reference to FIGS.
如图2-图5所示，根据本公开实施例的电池装置10可以包括：外壳1、多个电池和换热风道，外壳1上设置有第一气体接口11和第二气体接口12，其中，第一气体接口11和第二气体接口12中的一个为进气口，且另一个为出气口，两个气体接口的位置可以根据实际情况进行调整。As shown in FIG. 2 to FIG. 5, the battery device 10 according to an embodiment of the present disclosure may include: a casing 1, a plurality of batteries, and a heat exchange air passage, and the casing 1 is provided with a first gas interface 11 and a second gas interface 12, Wherein, one of the first gas interface 11 and the second gas interface 12 is an air inlet, and the other is an air outlet, and the positions of the two gas interfaces can be adjusted according to actual conditions.
如图2所示，多个电池设置在外壳1内，外壳1可以有效保护其内部的多个电池，多个电池分为多个电池组2，其中，换热风道3通过相邻的两个电池组2之间间隔开且相错设置以在外壳1内形成。例如，外壳1为长方体，相邻的两个电池组2在外壳1的长度方向上间隔开设置，而且相邻的电池组2可以在外壳1的宽度方向上相互错开设 置，也就是说，相邻的两个电池组2在外壳1的宽度方向延伸的侧壁上的投影并不会完全重合，这样相邻的电池组2之间可以形成串联换热风道3，而且如此设置的换热风道3可以经过每个电池组2，而且每个电池组2的电池的至少一个表面可以与换热风道3进行接触，从而可以使得每个电池与周围气流的良好换热性。As shown in FIG. 2, a plurality of batteries are disposed in the outer casing 1. The outer casing 1 can effectively protect a plurality of batteries therein, and the plurality of batteries are divided into a plurality of battery packs 2, wherein the heat exchange air passages 3 pass through two adjacent batteries. The battery packs 2 are spaced apart and arranged offset to form within the outer casing 1. For example, the outer casing 1 is a rectangular parallelepiped, two adjacent battery packs 2 are spaced apart in the longitudinal direction of the outer casing 1, and adjacent battery packs 2 can be arranged offset from each other in the width direction of the outer casing 1, that is, the phase The projections of the adjacent two battery packs 2 on the side walls extending in the width direction of the outer casing 1 do not completely coincide, so that the series heat exchange air passages 3 can be formed between the adjacent battery packs 2, and the heat exchange thus arranged The air duct 3 can pass through each of the battery packs 2, and at least one surface of the battery of each of the battery packs 2 can come into contact with the heat exchange ducts 3, so that each of the batteries can be made to have good heat exchange with the surrounding airflow.
用于冷却电池的气体介质适于从第一气体接口11和第二气体接口12中的一个流入换热风道3以顺次流经每个电池组2并从第一气体接口11和第二气体接口12中的另一个流出。也就是说，在吸风机50的作用下，气体介质可以从进气口进入到外壳1内，然后经过换热风道3与电池进行换热后，再从出气口排出，从而可以保证有持续流动的气体介质与电池装置10内的电池组2进行换热，进而可以保证电池装置10的工作可靠性。A gaseous medium for cooling the battery is adapted to flow from one of the first gas interface 11 and the second gas interface 12 into the heat exchange air passage 3 to sequentially flow through each of the battery packs 2 and from the first gas interface 11 and the second The other of the gas ports 12 flows out. That is to say, under the action of the suction fan 50, the gaseous medium can enter the outer casing 1 from the air inlet, and then exchange heat with the battery through the heat exchange air passage 3, and then discharge from the air outlet, thereby ensuring continuity. The flowing gaseous medium exchanges heat with the battery pack 2 in the battery unit 10, thereby ensuring the operational reliability of the battery unit 10.
由此，根据本公开实施例的电池装置10，通过设置换热风道3，可以使得每个电池均与气体介质直接接触，从而可以提高热传导效率。而且换热风道3既能兼顾电池的散热效果，使得电池散热良好，又可以减少电池之间的温差。还有，通过调节气体介质的流速(如调节风机20的转速、调节电池冷却空调40的风速)，可以减少电池模块之间的温差。Thus, according to the battery device 10 of the embodiment of the present disclosure, by providing the heat exchange duct 3, each of the batteries can be brought into direct contact with the gas medium, so that heat transfer efficiency can be improved. Moreover, the heat exchange air channel 3 can not only take into account the heat dissipation effect of the battery, but also make the battery heat dissipation good, and can reduce the temperature difference between the batteries. Also, by adjusting the flow rate of the gaseous medium (e.g., adjusting the rotational speed of the blower 20, adjusting the wind speed of the battery cooling air conditioner 40), the temperature difference between the battery modules can be reduced.
可选地，如图2所示，相邻的两个电池组2分别贴靠在外壳1的相对侧壁上且间隔布置。由此，相邻的两个电池组2之间可以有效限定出换热风道3，从而可以使得气体介质在电池组2之间流动顺畅且有序，进而可以提升电池的散热效果。相对侧壁可以为在外壳1的宽度方向上相对的两个侧壁。Alternatively, as shown in FIG. 2, two adjacent battery packs 2 are respectively abutted on opposite side walls of the outer casing 1 and spaced apart. Thereby, the heat exchange air passage 3 can be effectively defined between the adjacent two battery packs 2, so that the flow of the gas medium between the battery packs 2 can be smoothly and orderly, thereby improving the heat dissipation effect of the battery. The opposite side walls may be two side walls that are opposite in the width direction of the outer casing 1.
根据本公开的一个具体实施例，如图2所示，换热风道3包括：第一风道31和第二风道32，第一风道31位于电池组2和外壳1之间，第二风道32位于相邻的两个电池组2之间，每个电池组2对应至少一个第一风道31和至少一个第二风道32。According to a specific embodiment of the present disclosure, as shown in FIG. 2, the heat exchange air passage 3 includes: a first air passage 31 and a second air passage 32, and the first air passage 31 is located between the battery pack 2 and the outer casing 1, The two air ducts 32 are located between two adjacent battery packs 2, and each of the battery packs 2 corresponds to at least one first air duct 31 and at least one second air duct 32.
具体地，如图2所示，电池组2至少为三个，位于外侧的两个电池组2对应两个方向不同的第一风道31和一个第二风道32，位于内侧的电池组2对应一个第一风道31和两个第二风道32。也就是说，位于换热风道3的起始端和终止端处的电池组2周围可以分别具有两个第一风道31和一个第二风道32，位于起始端和终止端之间的电池组2可以设置有一个第一风道31和两个第二风道32。如此，第一风道31和第二风道32设置合理，每个电池组2中的电池均可以具有至少一个表面能够与换热风道3接触，从而可以保证电池装置10的散热效果。Specifically, as shown in FIG. 2, the battery pack 2 is at least three, and the two battery packs 2 located on the outer side correspond to the first air duct 31 and the second air duct 32 which are different in two directions, and the battery pack 2 located on the inner side Corresponding to one first air passage 31 and two second air passages 32. That is, the battery pack 2 located at the beginning end and the end end of the heat exchange air passage 3 may have two first air passages 31 and one second air passage 32, respectively, and a battery between the start end and the end end. Group 2 can be provided with a first air duct 31 and two second air ducts 32. As such, the first air duct 31 and the second air duct 32 are disposed reasonably, and the batteries in each of the battery packs 2 can have at least one surface capable of contacting the heat exchange air duct 3, so that the heat dissipation effect of the battery device 10 can be ensured.
根据本公开的一个可选实施例，如图2所示，每个电池组2包括至少一排电池。例如，每个电池组2可以包括四排电池，每排电池可以包括至少一个电池，例如，每排电池可以包括两个并列的电池。由此，每个电池组2设置合理，电池在外壳1内分布合理， 从而可以保证电池组2的分布密度和换热风道的布置顺利性。According to an alternative embodiment of the present disclosure, as shown in FIG. 2, each battery pack 2 includes at least one row of batteries. For example, each battery pack 2 can include four rows of batteries, each row of cells can include at least one battery, for example, each row of cells can include two juxtaposed cells. Thereby, each battery pack 2 is set reasonably, and the battery is distributed reasonably within the outer casing 1, so that the distribution density of the battery pack 2 and the arrangement of the heat exchange air passage can be ensured smoothly.
如图5所示，每个电池组2包括多排电池，相邻的两排电池之间限定出导风部4，导风部4连通电池组2相对两侧。需要说明的是，电池组2的相对两侧可以均设置有换热风道3的一部分，导风部4可以使得位于电池组2中间排的电池与气体介质的接触面积增大，从而可以使得电池装置10的散热效果更好。As shown in FIG. 5, each battery pack 2 includes a plurality of rows of batteries, and an air guiding portion 4 is defined between adjacent two rows of batteries, and the air guiding portion 4 communicates with opposite sides of the battery pack 2. It should be noted that the opposite sides of the battery pack 2 may each be provided with a part of the heat exchange air duct 3, and the air guiding portion 4 may increase the contact area of the battery located in the middle row of the battery pack 2 with the gas medium, thereby making it possible to The heat dissipation effect of the battery device 10 is better.
具体地，如图5所示，每个电池组2内的多排电池依次相错排布。也就是说，前一排的电池与后一排电池之间没有完全对应，会存在相互错开的一部分，这样位于后一排的电池所错开的一部分可以起到阻风的效果，这样可以利于气体进入导风部4。相错布置的多排电池可以一定程度上使得换热风道3内的气体介质易于进入导风部4，从而可以降低导风部4的导风难度，而且可以使得每个电池组2的散热效果好。Specifically, as shown in FIG. 5, the rows of cells in each of the battery packs 2 are sequentially arranged in phase. That is to say, there is no complete correspondence between the battery in the previous row and the battery in the last row, and there will be a part of each other that is staggered, so that a part of the battery in the latter row is staggered to hinder the wind, which can benefit the gas. Enter the air guiding portion 4. The multi-row battery arranged in a wrong phase can make the gas medium in the heat exchange air passage 3 easy to enter the air guiding portion 4, so that the air guiding difficulty of the air guiding portion 4 can be reduced, and the heat dissipation of each battery pack 2 can be made. The effect is good.
其中，可选地，如图3所示，电池装置10可以为多个，而且多个电池装置10层叠设置，多个电池装置10的换热风道3流向相同且串联。也就是说，上层的电池装置10和下层的电池装置10的结构可以相同，这样可以降低电池装置10的制造难度和布置难度。Optionally, as shown in FIG. 3, there may be a plurality of battery devices 10, and a plurality of battery devices 10 are stacked, and the heat exchange air passages 3 of the plurality of battery devices 10 flow in the same direction and in series. That is to say, the structure of the upper battery device 10 and the lower battery device 10 can be the same, which can reduce the manufacturing difficulty and the arrangement difficulty of the battery device 10.
另一种可选地，如图4所示，电池装置10为多个且层叠设置，多个电池装置10的换热风道3流向相反且串联。由此，可以降低电池装置10之间的连接管路的布置难度，从而可以使得多个电池装置10的气体介质流动顺畅且自然，可以使得电池装置10散热效果好。Alternatively, as shown in FIG. 4, the battery device 10 is plural and stacked, and the heat exchange air passages 3 of the plurality of battery devices 10 flow in opposite directions and are connected in series. Thereby, it is possible to reduce the difficulty in arranging the connection lines between the battery devices 10, so that the flow of the gas medium of the plurality of battery devices 10 can be smooth and natural, and the heat dissipation effect of the battery device 10 can be made good.
