近些年,新能源汽车有了飞跃式的发展,在电动汽车领域,动力电池作为电动汽车的动力源,起着不可替代的重要作用。其中,动力电池作为新能源汽车核心零部件在循环使用寿命上有着较高的要求。In recent years, new energy vehicles have developed by leaps and bounds. In the field of electric vehicles, power batteries, as the power source of electric vehicles, play an irreplaceable and important role. Among them, power batteries, as the core components of new energy vehicles, have high requirements on cycle life.
发明人发现,在一般的动力电池中,为了使得电池获得足够的功率,通常将电池的箱体内的多个电池单体进行堆叠设置。但是,电池单体在不断的充放电使用过程中会产生大量的热量和气体,从而会导致电池的内部温度上升以及体积膨胀,且多个电池单体堆叠设置会加剧这种现象的产生,进而严重影响到电池的使用性能和使用寿命,电池的使用可靠性较差。因此,在现有技术中,通常会在电池的内部设置用于为电池单体降温冷却的热管理部件,热管理部件内有供换热介质流通的通道,通过热管理部件与电池单体接触,以将电池单体产生的热量传递至热管理部件上,从而降低电池的内部温度,以起到对电池进行降温冷却的作用。然而,发明人发现,现有的热管理部件不易压缩,无法吸收成组的公差,温度调节效果有损失,无法适用于可压缩的使用场景。The inventors found that in general power batteries, in order to make the battery obtain sufficient power, multiple battery cells in the battery box are usually stacked. However, the battery cells will generate a lot of heat and gas during the continuous charging and discharging process, which will cause the internal temperature of the battery to rise and the volume to expand, and the stacking of multiple battery cells will aggravate the occurrence of this phenomenon, which will seriously affect the performance and service life of the battery, and the reliability of the battery is poor. Therefore, in the prior art, a thermal management component for cooling the battery cells is usually set inside the battery. There is a channel for the circulation of heat exchange medium in the thermal management component. The thermal management component contacts the battery cells to transfer the heat generated by the battery cells to the thermal management component, thereby reducing the internal temperature of the battery to cool the battery. However, the inventors found that the existing thermal management components are not easy to compress, cannot absorb the tolerance of the group, and the temperature regulation effect is lost, which cannot be applied to compressible usage scenarios.
基于上述考虑,发明人经过深入研究,设计了一种热管理部件100,参考图3-图4,热管理部件100包括分隔件2,分隔件2将热管理部件100的内腔1划分为多个子腔10,多个子腔10包括至少一个第一腔室11和至少一个第二腔室12,第一腔室11内设有换热介质,第二腔室12与第一腔室11不连通。Based on the above considerations, the inventors have designed a thermal management component 100 after in-depth research. Referring to Figures 3-4, the thermal management component 100 includes a partition 2, which divides the inner cavity 1 of the thermal management component 100 into a plurality of sub-cavities 10. The plurality of sub-cavities 10 include at least one first chamber 11 and at least one second chamber 12. A heat exchange medium is provided in the first chamber 11, and the second chamber 12 is not connected to the first chamber 11.
在这种结构的热管理部件100中,通过分隔件2将热管理部件100的内腔1分为互不连通的第二腔室12与第一腔室11,第一腔室11内设有换热介质,换热介质经第一腔室11流通,可以调节电池单体200的温度。由于第一腔室11和第二腔室12不连通,第二腔室12没有换热介质流过,从而热管理部件100对应第二腔室12的部分相对容易变形以吸收成组的公差,保证热管理部件100与电池单体200良好贴合的调温效果,进而有利于提升电池1000的使用性能和使用寿命,提高电池1000的使用可靠性。In the thermal management component 100 of this structure, the inner cavity 1 of the thermal management component 100 is divided into a second chamber 12 and a first chamber 11 which are not connected to each other by a separator 2. A heat exchange medium is arranged in the first chamber 11, and the heat exchange medium flows through the first chamber 11 to adjust the temperature of the battery cell 200. Since the first chamber 11 and the second chamber 12 are not connected, no heat exchange medium flows through the second chamber 12, so that the portion of the thermal management component 100 corresponding to the second chamber 12 is relatively easy to deform to absorb the tolerance of the group, thereby ensuring the temperature adjustment effect of the good fit between the thermal management component 100 and the battery cell 200, which is conducive to improving the performance and service life of the battery 1000 and improving the reliability of the battery 1000.
相关技术中的冷板内具有平行设置的多条流道,相邻流道之间的隔板垂直于冷板设置,使得冷板不易压缩,无法吸收成组的公差,无法适用于需求冷板可压缩的使用场景。根据本申请实施例的热管理部件100,通过设置流通换热介质的第一腔室11可以调节电池单体 200的温度,用于调节电池单体200热性能的控温***,并通过设置不流通换热介质的第二腔室12形成易变形区域,使得热管理部件100可以被压缩以吸收电池单体200的膨胀,实现吸收电池单体200成组的公差,即易变形区域有利于为电池单体200成组吸收公差,并提供一定的膨胀空间,进而有利于提升电池1000的使用性能和使用寿命,提高电池1000的使用可靠性。此外,设置第二腔室12可以调节热管理部件100的总体流量体积,实现减重。The cold plate in the related art has multiple flow channels arranged in parallel, and the partitions between adjacent flow channels are arranged perpendicular to the cold plate, so that the cold plate is not easy to compress and cannot absorb the tolerance of the group, and cannot be used in the use scenario that requires the cold plate to be compressible. According to the thermal management component 100 of the embodiment of the present application, the temperature of the battery cell 200 can be adjusted by setting the first chamber 11 through which the heat exchange medium circulates, and the temperature control system for adjusting the thermal performance of the battery cell 200 is used, and the second chamber 12 through which the heat exchange medium does not circulate is formed to form an easily deformable area, so that the thermal management component 100 can be compressed to absorb the expansion of the battery cell 200, and realize the absorption of the tolerance of the battery cell 200 group, that is, the easily deformable area is conducive to absorbing the tolerance of the battery cell 200 group, and provides a certain expansion space, which is conducive to improving the performance and service life of the battery 1000, and improving the reliability of the battery 1000. In addition, the second chamber 12 is provided to adjust the overall flow volume of the thermal management component 100 to achieve weight reduction.

以下实施例为了方便说明,以本申请一实施例的一种热管理部件100为例进行说明。For the convenience of description, the following embodiments are described by taking a thermal management component 100 according to an embodiment of the present application as an example.
请参照图3和图4,图4为本申请一些实施例提供的热管理部件100的结构示意图。热管理部件100包括分隔件2,分隔件2将热管理部件100的内腔1划分为多个子腔10,多个子腔10包括至少一个第一腔室11和至少一个第二腔室12,第一腔室11内设有换热介质。Please refer to Figures 3 and 4, Figure 4 is a schematic diagram of the structure of the thermal management component 100 provided in some embodiments of the present application. The thermal management component 100 includes a partition 2, which divides the inner cavity 1 of the thermal management component 100 into a plurality of sub-cavities 10, the plurality of sub-cavities 10 including at least one first chamber 11 and at least one second chamber 12, and a heat exchange medium is provided in the first chamber 11.
可选地,热管理部件100上具有与第一腔室11连通的换热介质进入接口5和换热介质流出接口6。换热介质可以通过换热介质进入接口5进入第一腔室11,然后通过换热介质流出接口6流出第一腔室11,从而可以通过第一腔室11为电池单体200调节温度。例如在冷却场景下,换热介质在第一腔室11内流通,能带走电池单体200产生的热量,降低电池单体200的温度。Optionally, the thermal management component 100 has a heat exchange medium inlet interface 5 and a heat exchange medium outlet interface 6 that are connected to the first chamber 11. The heat exchange medium can enter the first chamber 11 through the heat exchange medium inlet interface 5, and then flow out of the first chamber 11 through the heat exchange medium outlet interface 6, so that the temperature of the battery cell 200 can be adjusted through the first chamber 11. For example, in a cooling scenario, the heat exchange medium circulates in the first chamber 11, which can take away the heat generated by the battery cell 200 and reduce the temperature of the battery cell 200.
由于第一腔室11和第二腔室12不连通,第二腔室12没有换热介质流过,热管理部件100对应第二腔室12的部位形成为易变形区域,以用于吸收电池单体200成组的公差,使得热管理部件100具有可压缩性能,进而有利于提升电池1000的使用性能和使用寿命。Since the first chamber 11 and the second chamber 12 are not connected, no heat exchange medium flows through the second chamber 12, and the portion of the thermal management component 100 corresponding to the second chamber 12 is formed as an easily deformable area to absorb the tolerance of the battery cell 200 grouping, so that the thermal management component 100 has compressible properties, which is beneficial to improving the performance and service life of the battery 1000.
在一些实施例中,如图4和图8所示,第一腔室11和第二腔室12中至少一个为多个。设置多个第一腔室11,能促进换热介质循环,加快散热效率;设置多个第二腔室12,有利于提升压缩性能并实现减重。In some embodiments, as shown in Figures 4 and 8, at least one of the first chamber 11 and the second chamber 12 is multiple. Providing multiple first chambers 11 can promote the circulation of heat exchange medium and increase heat dissipation efficiency; providing multiple second chambers 12 is conducive to improving compression performance and achieving weight reduction.
在一些实施例中,如图4所示,第一腔室11和第二腔室12沿与热管理部件100的厚度 方向相垂直的方向交替设置。由此,使得第一腔室11和第二腔室12都可以分别接触热管理部件100的厚度两侧,可提升降温效果,使得换热更均匀,并提升热管理部件100的可压缩性能。如图4所示,第一腔室11和第二腔室12连续交替设置。In some embodiments, as shown in FIG4 , the first chamber 11 and the second chamber 12 are alternately arranged along a direction perpendicular to the thickness direction of the thermal management component 100. Thus, the first chamber 11 and the second chamber 12 can contact both sides of the thickness of the thermal management component 100, respectively, which can improve the cooling effect, make the heat exchange more uniform, and improve the compressibility of the thermal management component 100. As shown in FIG4 , the first chamber 11 and the second chamber 12 are continuously alternately arranged.
根据本申请实施例的热管理部件100,通过设置流通换热介质的第一腔室11可以调节电池单体200的温度,用于调节电池单体200热性能的控温***,并通过设置不流通换热介质的第二腔室12形成易变形区域,使得热管理部件100可以被压缩以吸收电池单体200的膨胀,实现吸收电池单体200成组的公差,即易变形区域有利于为电池单体200成组吸收公差,并提供一定的膨胀空间,提高电池1000的使用可靠性。此外,设置第二腔室12可以调节热管理部件100的总体流量体积,实现减重。According to the thermal management component 100 of the embodiment of the present application, the temperature of the battery cell 200 can be adjusted by setting the first chamber 11 through which the heat exchange medium flows, and the temperature control system for adjusting the thermal performance of the battery cell 200 is used, and the second chamber 12 through which the heat exchange medium does not flow is formed to form an easily deformable area, so that the thermal management component 100 can be compressed to absorb the expansion of the battery cell 200, and achieve the absorption of the tolerance of the battery cell 200 grouping, that is, the easily deformable area is conducive to absorbing the tolerance of the battery cell 200 grouping, and provides a certain expansion space, thereby improving the reliability of the battery 1000. In addition, the second chamber 12 can adjust the overall flow volume of the thermal management component 100 to achieve weight reduction.
在一些实施例中,结合图3和图4,热管理部件100包括两个板体3,两个板体3沿热管理部件100的厚度方向Z排列且两个板体3之间形成内腔1,分隔件2包括隔板部21,隔板部21的两端分别对应支撑两个板体3,隔板部21的两端之间的部分的厚度方向上的两侧分别设有子腔10。In some embodiments, in combination with Figures 3 and 4, the thermal management component 100 includes two plate bodies 3, the two plate bodies 3 are arranged along the thickness direction Z of the thermal management component 100 and an inner cavity 1 is formed between the two plate bodies 3, and the partition 2 includes a partition portion 21, the two ends of the partition portion 21 respectively support the two plate bodies 3, and sub-cavities 10 are respectively provided on both sides of the thickness direction of the part between the two ends of the partition portion 21.
例如在图3所示的示例中,两个板体3分为第一板体31和第二板体32,第一板体31和第二板体32沿着热管理部件100的厚度方向Z排列,第一板体31位于第二板体32的上方,第一板体31和第二板体32之间形成内腔1。隔板部21的上端止抵第一板体31,隔板部21的下端止抵第二板体32,从而使得隔板部21可以起到分隔作用,以在隔板部21的厚度两侧分别形成子腔10。For example, in the example shown in FIG. 3 , the two plates 3 are divided into a first plate 31 and a second plate 32, the first plate 31 and the second plate 32 are arranged along the thickness direction Z of the thermal management component 100, the first plate 31 is located above the second plate 32, and an inner cavity 1 is formed between the first plate 31 and the second plate 32. The upper end of the partition part 21 stops against the first plate 31, and the lower end of the partition part 21 stops against the second plate 32, so that the partition part 21 can play a partitioning role, so as to form sub-cavities 10 on both sides of the thickness of the partition part 21.
在上述技术方案中,分隔件2通过设置隔板部21,通过隔板部21的两端分别支撑热管理部件100的厚度方向排列的两个板体3,可以简单且有效地将内腔1划分成多个子腔10,且隔板部21两侧的子腔10均可以用于与热管理部件100的厚度方向的至少一个板体3充分热交换,增强了子腔10中的换热介质与电池单体200之间的热交换能力,提升了温度调节效果。而且隔板部21可以支撑热管理部件100的厚度方向排列的两个板体3,使得热管理部件100可以与电池单体200良好贴合传热,进一步提高温度调节效果。In the above technical solution, the partition 2 is provided with a partition part 21, and the two ends of the partition part 21 respectively support the two plates 3 arranged in the thickness direction of the thermal management component 100, so that the inner cavity 1 can be simply and effectively divided into a plurality of sub-cavities 10, and the sub-cavities 10 on both sides of the partition part 21 can be used for full heat exchange with at least one plate 3 in the thickness direction of the thermal management component 100, thereby enhancing the heat exchange capacity between the heat exchange medium in the sub-cavity 10 and the battery cell 200, and improving the temperature regulation effect. In addition, the partition part 21 can support the two plates 3 arranged in the thickness direction of the thermal management component 100, so that the thermal management component 100 can fit well with the battery cell 200 for heat transfer, further improving the temperature regulation effect.
在一些实施例中,隔板部21的厚度小于板体3的厚度。由此,热管理部件100的结构简单、容易加工、节约成本、可实现减重,通过设置隔板部21的厚度小于板体3的厚度,使得热管理部件100容易受压缩变形,具有较好的吸收公差效果,提升温度调节效果。In some embodiments, the thickness of the partition portion 21 is less than the thickness of the plate body 3. Therefore, the thermal management component 100 has a simple structure, is easy to process, saves costs, and can achieve weight reduction. By setting the thickness of the partition portion 21 to be less than the thickness of the plate body 3, the thermal management component 100 is easily deformed by compression, has a better tolerance absorption effect, and improves the temperature regulation effect.
在一些实施例中,隔板部21的两端的连线方向与热管理部件100的厚度方向相交锐角 例如图4中所示的a1。图4中,a1为隔板部21的两端的连线方向与热管理部件100的厚度方向的夹角,a1为锐角,a1与a2互补,a2为钝角。隔板部21相对于热管理部件100的厚度方向Z是倾斜的,而不是垂直或平行的,使得热管理部件100受压缩时隔板部21容易形变,进而提升了热管理部件100的可压缩性。结构简单,设计巧妙。In some embodiments, the connecting direction of the two ends of the partition portion 21 intersects the thickness direction of the thermal management component 100 at an acute angle, such as a1 shown in FIG4 . In FIG4 , a1 is the angle between the connecting direction of the two ends of the partition portion 21 and the thickness direction of the thermal management component 100 , a1 is an acute angle, a1 and a2 are complementary, and a2 is an obtuse angle. The partition portion 21 is inclined relative to the thickness direction Z of the thermal management component 100, rather than vertical or parallel, so that the partition portion 21 is easily deformed when the thermal management component 100 is compressed, thereby improving the compressibility of the thermal management component 100. The structure is simple and the design is ingenious.
在一些实施例中,隔板部21包括沿着从上述两端中的一端到另一端的方向依次设置的多个板段210,多个板段210非共面设置,以使相邻的两个板段210的连接处形成折弯区域211。例如在图4所示的示例中,隔板部21包括沿着从上端到下端的方向或者从下端到上端的方向依次设置的两个板段210,两个板段210的连接处形成折弯区域211。In some embodiments, the partition portion 21 includes a plurality of plate segments 210 sequentially arranged along a direction from one end to the other end of the two ends, and the plurality of plate segments 210 are arranged non-coplanarly so that a bending area 211 is formed at the connection between two adjacent plate segments 210. For example, in the example shown in FIG4 , the partition portion 21 includes two plate segments 210 sequentially arranged along a direction from the upper end to the lower end or from the lower end to the upper end, and a bending area 211 is formed at the connection between the two plate segments 210.
在上述技术方案中,折弯区域211使得隔板部21更易变形,有利于为电池单体200成组吸收公差及提供一定的膨胀空间。此外,隔板部21在起到易变形作用的同时,在电池单体200循环膨胀后期,为热管理部件100提供一定的支撑作用,起到防压溃作用,避免热管理部件100在循环后期被压扁后,导致第一腔室11无冷却介质,影响传热的同时,降低散热效果。In the above technical solution, the bending area 211 makes the partition part 21 easier to deform, which is conducive to absorbing tolerances and providing a certain expansion space for the battery cells 200. In addition, while the partition part 21 plays a role of easy deformation, it also provides a certain support for the thermal management component 100 in the late stage of cyclic expansion of the battery cells 200, plays a role in preventing crushing, and prevents the thermal management component 100 from being flattened in the late stage of the cycle, resulting in the first chamber 11 being without cooling medium, affecting heat transfer and reducing the heat dissipation effect.
在一些实施例中,如图4所示,多个板段210可以平行设置,从而提高对热管理部件100的支撑效果。In some embodiments, as shown in FIG. 4 , a plurality of plate segments 210 may be arranged in parallel, thereby improving the supporting effect on the thermal management component 100 .
在一些实施例中,如图4所示,折弯区域211可以为台阶状且通过倒圆弧与板段210衔接,使得折弯区域211与两边的板段210平滑过渡,避免在折弯区域211与板段210连接处发生断裂。In some embodiments, as shown in FIG. 4 , the bending area 211 may be step-shaped and connected to the plate segment 210 through a rounded arc, so that the bending area 211 and the plate segments 210 on both sides have a smooth transition to avoid fracture at the connection between the bending area 211 and the plate segment 210 .
在一些实施例中,参考图3和图4,分隔件2包括多个隔板部21,这样,热管理部件100内可形成更多数量的子腔10,提升了热管理部件100的温度调节均匀性和可压缩性。在图4中,风格件包括4个隔板部21,形成了5个子腔10。In some embodiments, referring to Figures 3 and 4, the partition 2 includes a plurality of partition portions 21, so that a greater number of sub-cavities 10 can be formed in the thermal management component 100, thereby improving the temperature regulation uniformity and compressibility of the thermal management component 100. In Figure 4, the style piece includes four partition portions 21, forming five sub-cavities 10.
每个隔板部21的长度方向与热管理部件100的长度方向相同,可选地,隔板部21的长度方向与热管理部件100的长度方向X平行或大体平行,多个隔板部21沿宽度方向Y间隔设置,有利于隔板部21较均匀支撑热管理部件100,使热管理部件100整体受力均匀,提升热管理部件100的可压缩性,且可简化制造工艺。同时有利于换热介质如冷却介质在各第一腔室11内流通,提升温度调节的均匀性,进而提升温度调节效果。The length direction of each partition part 21 is the same as the length direction of the thermal management component 100. Optionally, the length direction of the partition part 21 is parallel or substantially parallel to the length direction X of the thermal management component 100. Multiple partition parts 21 are arranged at intervals along the width direction Y, which is conducive to the partition part 21 to support the thermal management component 100 more evenly, so that the thermal management component 100 is uniformly stressed as a whole, the compressibility of the thermal management component 100 is improved, and the manufacturing process can be simplified. At the same time, it is conducive to the circulation of heat exchange medium such as cooling medium in each first chamber 11, improving the uniformity of temperature regulation, and thus improving the temperature regulation effect.
在一些实施例中,如图3和图4所示,第一腔室11和第二腔室12均沿热管理部件100的长度方向X延伸,且第一腔室11和第二腔室12沿热管理部件100的宽度方向Y交替设 置。这样,使热管理部件100的长度方向上都具有降温作用,充分利用热管理部件100的空间。第一腔室11和第二腔室12沿着热管理部件100的宽度方向依次交替设置,提升热管理部件100整体的温度均匀性和受力均匀性,能扩大换热介质的流量,提升散热效果和可压缩性能。In some embodiments, as shown in FIG. 3 and FIG. 4 , the first chamber 11 and the second chamber 12 both extend along the length direction X of the thermal management component 100, and the first chamber 11 and the second chamber 12 are alternately arranged along the width direction Y of the thermal management component 100. In this way, the thermal management component 100 has a cooling effect in the length direction, and the space of the thermal management component 100 is fully utilized. The first chamber 11 and the second chamber 12 are alternately arranged in sequence along the width direction of the thermal management component 100, which improves the overall temperature uniformity and force uniformity of the thermal management component 100, can expand the flow rate of the heat exchange medium, and improve the heat dissipation effect and compressibility.
在一些实施例中,如图4所示,多个隔板部21中的至少两个相对热管理部件100的厚度方向Z的倾斜方向不同。图4所示实施例中,相邻两个隔板部相对厚度方向Z的倾斜方向不同,倾斜方向不同的隔板部21受到的力可相互抵消或者部分抵消,提升了热管理部件100的可压缩性能,以及隔板部21的整体支撑性能,使得热管理部件100可以与电池单体200良好贴合,保证温度调节效果,并且有利于子腔10的形状和大小设计,保证换热介质的流量满足设计要求。In some embodiments, as shown in FIG4 , at least two of the plurality of partitions 21 have different inclination directions relative to the thickness direction Z of the thermal management component 100. In the embodiment shown in FIG4 , the inclination directions of two adjacent partitions relative to the thickness direction Z are different, and the forces on the partitions 21 with different inclination directions can offset each other or partially offset each other, thereby improving the compressibility of the thermal management component 100 and the overall support performance of the partitions 21, so that the thermal management component 100 can be well fitted with the battery cell 200, ensuring the temperature regulation effect, and facilitating the shape and size design of the sub-cavity 10, ensuring that the flow rate of the heat exchange medium meets the design requirements.
在一些实施例中,如图4所示,相邻的两个隔板部21相对热管理部件100的厚度方向的倾斜方向相反。其中,倾斜方向为热管理部件100的厚度方向转动最小角度以与隔板部21平行所沿的转动方向,即倾斜方向为热管理部件100的厚度方向转动最小角度到达平行隔板部21期间所沿的转动方向。In some embodiments, as shown in FIG4 , the inclination directions of two adjacent partition portions 21 relative to the thickness direction of the thermal management component 100 are opposite. The inclination direction is the rotation direction along which the thermal management component 100 rotates at the minimum angle in the thickness direction to be parallel to the partition portion 21, that is, the inclination direction is the rotation direction along which the thermal management component 100 rotates at the minimum angle in the thickness direction to be parallel to the partition portion 21.
例如图4中所示,厚度方向Z沿顺时针方向转动角度a1可与第一隔板部2101平行,顺时针方向即为第一隔板部2101的倾斜方向,厚度方向Z沿逆时针方向转动角度a3可与第二隔板部2102平行,逆时针方向即为第二隔板部2102的倾斜方向,由此可见第二隔板部2102与第一隔板部2101的倾斜方向相反。For example, as shown in Figure 4, the thickness direction Z can be rotated clockwise at an angle a1 to be parallel to the first partition portion 2101, and the clockwise direction is the inclination direction of the first partition portion 2101. The thickness direction Z can be rotated counterclockwise at an angle a3 to be parallel to the second partition portion 2102, and the counterclockwise direction is the inclination direction of the second partition portion 2102. It can be seen that the inclination directions of the second partition portion 2102 and the first partition portion 2101 are opposite.
相邻两个隔板部21受到的力可以相互抵消或者部分抵消,可以提升热管理部件100的可压缩性能。可选地,相邻两个隔板部21的延伸方向相互交叉,这样,相邻两个隔板部21一端间隔小,另一端间隔大,如图4所示,部分第一腔室11和第二腔室12呈现梯形,从而提升换热效果和压缩效果。而且,此种连接方式有利于分隔件2的一体成型。The forces on two adjacent partitions 21 can offset each other or partially offset each other, which can improve the compressibility of the thermal management component 100. Optionally, the extension directions of the two adjacent partitions 21 intersect each other, so that the interval between the two adjacent partitions 21 is small at one end and large at the other end. As shown in FIG. 4, part of the first chamber 11 and the second chamber 12 are trapezoidal, thereby improving the heat exchange effect and the compression effect. Moreover, this connection method is conducive to the integral molding of the partition 2.
在一些实施例中,当第一腔室11和第二腔室12均沿热管理部件100的长度方向X延伸,且第一腔室11和第二腔室12沿热管理部件100的宽度方向Y交替设置时,可以是相邻的两个隔板部21相对热管理部件100的厚度方向Z的倾斜方向相反,连接部22连接相邻的两个隔板部21彼此靠近的一端,此时,每个隔板部21两侧分别为第一腔室11和第二腔室12,且第一腔室11和第二腔室12均为梯形,且上下底方向相反,从而可以充分利用空间,有利于压缩和温度调节。In some embodiments, when the first chamber 11 and the second chamber 12 both extend along the length direction X of the thermal management component 100, and the first chamber 11 and the second chamber 12 are alternately arranged along the width direction Y of the thermal management component 100, the two adjacent partition portions 21 may be inclined in opposite directions relative to the thickness direction Z of the thermal management component 100, and the connecting portion 22 connects the ends of the two adjacent partition portions 21 that are close to each other.
