热交换装置
本申请要求于2015年7月17日提交中国专利局、申请号为201510423629.1、发明名称为“热交换装置”,及2015年12月25日提交中国专利局、申请号为201510997992.4、发明名称为“一种换热装置及换热器”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种热交换装置,应用于电动汽车电池等的热管理系统。
背景技术
一般的,在电动汽车的电池热管理系统中,电动汽车的电池工作时会产生热量,为保证电池的正常工作,需要对电池进行冷却,利用冷却液冷却是一种较常用的方式。通常的电池冷却装置包括换热器和膨胀阀,液态制冷剂通过膨胀阀的节流作用后进入换热器,制冷剂与冷却液在换热器中进行热交换,冷却液被冷却,冷却了的冷却液可以直接或者间接用于电池组冷却电池,冷却液吸收电池组的热量后温度升高,再回到换热器进行冷却,如此循环。
现有热管理系统中,换热器和膨胀阀都是单独的部件,通过管道等方式进行连接。换热器与膨胀阀之间有较大的距离,经过膨胀阀后的汽液两相状态的制冷剂会在这一段距离发生流动状态的变化,如汽液分层,这样会影响制冷效果。另外管路等连接部件会导致整个组件重量较重,安装环境复杂,还使整个组件的抗振性较差,容易出现连接管断裂等现象,成本也较高。
因此,如何提供一种结构紧凑、便于安装、抗振性能好且使用成本较低的换热器和膨胀阀集成装置,是本领域技术人员亟待解决的技术问题。

具体实施方式
下面结合附图,对本发明的具体实施方式进行说明。
图1至图7示出了本发明的一实施例的热交换装置,如图所示,热交换装置包括换热器10、阀组件、以及用以固定热交换装置的安装板3,阀组件包括阀芯组件22、线圈组件21。同时,安装板3还与换热器10、线圈组件21和阀芯组件22固定安装。
换热器10可以作为蒸发器使用,所述换热器10包括用于冷却液流通的第二流道及用于制冷剂流通的第一流道,其中所述第一流道包括制冷剂进口及制冷剂出口,第二流道包括冷却液进口及冷却液出口。所述冷却液进口可以与第二接管4连接,所述冷却液出口可以与第一接管1连接,所述制冷剂出口可以与第三接管5连接,所述制冷剂进口可以直 接与阀芯组件22的出口连通。
所述换热器10还包括换热芯体、以及分别位于所述换热芯体两端的端板6和底板7。其中,换热芯体包括相互间隔层叠设置的若干个第一板片和若干个第二板片,各第一板片和两边相邻的第二板片之间形成第一通道和第二通道,第一板片和一边相邻的第二板片之间形成第一通道,则该第一板片和另一边相邻的第二板片之间形成第二通道。其中,第一通道为第一流道的一部分,第二通道为第二流道的一部分。在本实施例中,第一板片和第二板片采用同一形状结构的板片8,叠装时,第一板片相对于第二板片旋转180°进行叠装。采用同一形状结构的板片8,在加工板片时只需要一副模板,加工简单,加工工序少,可以节省成本。
所述制冷剂进口与制冷剂出口、以及所述冷却液进口与冷却液出口可以设置于所述换热器10的同侧或者异侧。所述第一接管1、第二接管4及第三接管5均可以为铝合金管,可以通过钎焊的方式与换热器10连接在一起;另外三个接管中也可以有部分或全部是通过钎焊与安装板3固定连接并通过安装板3与换热器10连接。
在实施方式中,换热器10为板式换热器,也可以是板翅式换热器,另外其它类型的换热器也同样能够适用。如图2和图3所示,安装板3是由金属板材经冲压、机加工等工序加工形成或者压铸成型而成,板材可以采用铝合金材料。所述安装板3包括配合部及位于配合部外侧的若干安装结构36。在穿过安装结构36的安装方向上,安装结构36完全暴露在所述换热器10的外面,安装结构36与换热芯体不发生干涉。如此设置,在用螺钉(未图示)穿过所述安装结构36而将热交换装置安装固定时,不会碰到换热器10。这种设计一方面降低了热交换装置的成本和安装难度,另一方面也降低了在安装时对换热器10的损坏机率。
这里应当指出,可以根据热交换装置的具体安装位置的需要来设置安装板3的形状结构以及安装结构36的具体位置和数量。
配合部包括用于固定安装第一接管1的第一通孔353、用于固定安装第二接管4的第二通孔352、用于固定安装第三接管5的第三通孔351、用于固定安装第四接管9的第四通孔34以及用于固定安装线圈组件21和阀芯组件22的凸台部32。其中第一通孔353和第二通孔352与换热器10的第二流道连通,第三通孔351与换热器10的第一流道连通。在本实施例中,第一通孔353和第二通孔352分别与换热器10的冷却液出口和冷却液进口连通,第三通孔351与换热器10的制冷剂出口连通。
第一通孔353和冷却液出口均为圆形且非同轴设置,第一通孔353的内径大于冷却液出口的内径,以形成台阶,从而便于与第一接管1的一端进行对接和定位,便于第一接管1的安装。第二通孔352和冷却液出口均为圆形且非同轴设置,第二通孔352的内径大于冷却液出口的内径,以形成台阶,从而便于与第二接管4的一端进行对接和定位,便于第二接管4的安装。同样的,第三通孔351和制冷剂出口均为圆形且非同轴设置,第三通孔351的内径大于制冷剂出口的内径,以形成台阶,从而便于与第三接管5的一端进行对接和定位,便于第三接管5的安装。
凸台部32凸起于安装板3板平面一定的高度,安装板3在凸台部32所在部位设置有一贯穿凸台部32和安装板3的安装孔,安装孔包括大部分位于凸台部32的阀芯容纳腔33,阀芯容纳腔33从下至上依次包括内径逐渐增大的第一腔331、第二腔332和第三腔333,其中凸台部32的第一腔331处的内壁设置有用于固定阀芯组件22的螺纹接口部321,第二腔332与第一腔331之间形成的台阶部用于安置密封圈,通过设置密封圈增加阀芯组件22固定在阀芯容纳腔33内的密封性。
凸台部32的外侧壁还设置有用于固定线圈组件21的螺纹固定部322,通过螺纹固定部322使线圈组件21与安装板3固定安装。当然,螺纹固定部322也可以直接设置在安装板3的板面,另外也可以设置在阀芯组件。在本实施例中,螺纹固定部322设置在凸台部32可以提高线 圈组件的安装稳定性。
这里将安装板3具有凸台部32的一面定义为安装板3的正面,将与换热器相接触的一面定义为安装板3的反面。在安装板3的反面还开设有一连接槽31,连接槽31连通第四通孔34和阀芯容纳腔33,第四通孔34通过连接槽31可以与阀芯容纳腔连通。
在安装板3的反面还可以设置有多个凸起于安装板3背面一定高度的定位凸台37,通过定位凸台37可以便于安装板3与换热器10的定位和安装。
如图4所示,端板6包括位于四个角的第三孔口63、第四孔口62、第一孔口61和第二孔口64,其中在第二孔口64的外周侧还形成有一凸出于端板6的板平面一定高度的中空的定位部65,定位部65的内径小于等于第二孔口64的内径,定位部65可以是通过冲压加工形成的冲孔结构。
在端板6上还可以设置与定位凸台37相对应的定位孔66,在安装时,通过定位凸台37与定位孔66的配合安装,可以快速的定位换热器和安装板,便于安装,也能够提高热交换装置的安装精度和良品率。
其中,第三孔口63与第一通孔353相对应,第四孔口62与第二通孔352相对应,第一孔口61与第三通孔351相对应,第二孔口64与阀芯容纳腔33相对应,第二孔口64在安装板3的投影与阀芯容纳腔33在安装板3的投影部分重合或者完全重合。并且阀芯容纳腔33的内径大于等于第二孔口64的内径,可以使阀芯组件22的一部分穿过阀芯容纳腔33伸入定位部65中。并且定位部65凸出于端板6板平面的方向与凸台部32凸出于安装板3正面的方向相反。
当然定位部65凸出于端板6板平面的方向也可以与凸台部32凸出于安装板3正面的方向相同,此时,定位部65的高度应小于连接槽31的深度。本实施例的定位部65的设置方式一方面可以减小安装板3的厚 度,另一方面可以进一步的减小阀芯组件22的出口与换热器10之间的距离,从而提高换热器的换热性能。
如图6和图7所示,阀芯组件22包括阀座220,阀座220包括第一部225和第二部221,其中第二部分221中设置有节流孔。第一部225的外壁设置有与螺纹接口部321相对应的外螺纹,第一部225可以通过第一密封圈226和螺纹与凸台部32密封固定,第二部221的一部分可以通过第二密封圈223与定位部65密封连接。第二部221设置有阀芯进口通道222和阀芯出口通道224,节流孔设置在阀芯进口通道222和阀芯出口通道224之间,阀芯进口通道222可以通过节流孔连通阀芯出口通道224,阀芯组件可以通过设置的阀针与节流孔的抵近和远离来控制节流孔的大小。并且,第二部221的外径小于阀芯容纳腔33的内径,第二部221不与阀芯容纳腔33的内壁接触,阀芯进口通道222的进口可以为多个,可以是阀芯进口通道222的至少一部分与连接槽31相对,阀芯进口通道222可以通过安装板3在阀芯容纳腔33所在部位的内壁与第二部221之间的空间与连接槽31连通,这样便于制冷剂从阀芯容纳腔33流入阀芯进口通道222。
第二部221的下端伸入定位部65中,并通过设置第二密封圈223密封,阀芯出口通道224可以直接与换热器10的第一流道连通。阀芯进口通道222的至少一部分位于定位部65上方的阀芯容纳腔33,连接槽31可以通过安装板3在阀芯容纳腔33所在部位的内壁和第二部221之间的空间与阀芯进口通道222连通。
当然,也可以不设置定位部65,此时第二部221的外径大于第二孔口64的内径,阀芯出口通道224的出口的内径小于等于第二孔口64的内径,使第二部221压紧抵靠在端板6上。本实施例通过设置定位部65,可以提高第二部221与定位部65密封性能,防止内漏。
这样,制冷剂从第二孔口64流入后,经过连接槽31流向阀芯进口 通道222,经过阀组件节流后的制冷剂通过阀芯出口通道224直接流入换热器10,可以很好的减少制冷剂的流动行程,从而减小在流动过程中产生气液分离现象,提高换热器的换热性能,可以较好的控制过热度,而且还能够提高热交换装置的抗振性能。
组装时,板片8、端板6、底板7、安装板、第一接管1、第二接管4及第三接管5通过钎焊的形式焊接在一起。焊接前,首先将板片8、端板6、底板7、安装板、第一接管1、第二接管4及第三接管5组装完成,利用专用的工装夹具进行压紧固定;然后,再将压装好的板片8、端板6、底板7、安装板、第一接管1、第二接管4及第三接管5放入炉中进行焊接。焊接的方式可以采用真空炉进行真空钎焊或者采用隧道炉进行氮气保护焊。焊接好以后,将阀芯组件22和线圈组件21依次安装于安装板的凸台部32。
图8示出了本发明的另一实施例,在本实施例中,安装板包括第一安装板301和第二安装板302,其中第一安装板301的结构与上述实施例中的安装板3的结构相同或者相近似,第一安装板301的正面设置有凸台部3201,凸台部3201形成有贯穿第一安装板301的阀芯容纳腔3301,第一安装板301的背面也设置有一连接槽311。第二安装板302与第一安装板301相配合,并且设置有与阀芯容纳腔331相配合的定位部3302,定位部3302的凸出于第二安装板302的方向与凸台部3201凸出于第一安装板301的方向相反,定位部3302的结构和功能与上述实施例中的定位部65相同或相似,在本实施例中,端板6中无需再设置定位部65。其中,阀座220的第一部225与凸台部3201密封固定,阀座220的第二部221与定位部332密封固定。
第一安装板301和第二安装板302可以通过焊接等方式连接在一起,本实施例的结构简单,安装方便,稳定性好。
本实施例的其它结构和功能与上述实施例相同或者相似,这里不再 一一赘述。
图9至图10示出了又一实施例,与第一实施例相比,在本实施例中,端板6中无需设置定位部65,在安装板3的反面还设置有定位部131b,定位部131b中设置有与凸台部32的阀芯容纳腔33相连通的贯穿孔131d。定位部131b的功能和作用与定位部65相同。
阀芯组件22与凸台部32组装固定,定位部131b包括凸起段131b2和隔离段131b1,定位部131b的凸起段131b2位于端板6和底板7之间,凸起段131b2外径小于第二孔口64的内径,凸起段131b2的端部可以穿过第二孔口64。定位部131b的隔离段131b1位于换热器芯体外部,隔离段131b1位于端板6与安装板之间,且隔离段131b1靠近连接槽31,隔离段131b1与凸台部之间形成第一开口131c,连接槽31通过第一开口131c与阀芯容纳腔33连通。这样,可缩短制冷剂进入第一通道的路径,防止经阀组件后的制冷剂在较长管路中出现气液分离;隔离段131b1与端板6密封固定,隔离段131b1隔离连接槽31与第一流道的连通,防止制冷剂不经过阀组件直接进入第一流道。
在本实施例中,换热器为多流程换热器。能更加清楚地了解换热器芯体内部结构,请参照图9和图10,图9为换热装置100的局部立体剖视示意图,图10为安装板的剖视示意图。换热器芯体11包括多个层叠设置的板片,板片包括多个第一板片111、多个第二板片112和至少一个第三板片113;第一板片111和第二板片112层叠形成第一通道和第二通道,除最靠边的两片板片外,多数板片的两侧分别为第一通道和第二通道,如一第一板片及与该板片相邻的两片第二板片的其中之一形成第一通道,那与另一第二板片则形成第二通道,第一通道和第二通道不相通。
第一板片111、第二板片112各自包括第一孔口23、第二孔口24、第三孔口(图中未示出)、第四孔口(图中未示出),各板片上的第一孔 口23对齐形成第一孔道231,各板片上的第二孔口24对齐形成第二孔道241,各板片上的第三孔口对齐形成第三孔道(图中未示出),各板片上的第四孔口对齐形成第四孔道(图中未示出)。其中,换热器芯体的第一孔道、第二孔道和第一通道相连通,第三孔道、第四孔道和第二通道相连通。
参考图11,第三板片113包括第一阻挡部19a和第二孔口24,第三板片113的第二孔口24与第一板片111的第二孔口24、第二板片112的第二孔口24对齐形成第二孔道,第一阻挡部19a位于第三板片113的与第一板片111、第二板片112的第一孔口23对应位置,换热器芯体11的第一孔道231被第一阻挡部19a分隔形成至少两个子孔道231a、231b,第一通道通过该第三板片113分割为至少两个换热段,换热段包括第一换热段101和第二换热段102,如图中箭头所示,第一换热段101和第二换热段102内流体的流动方向相反,第一孔道的各子孔道通过第二孔道与相邻的子孔道连通。
另外,制冷剂进入换热器芯体时,制冷剂大部分为液体,液体密度远大于气体,为了防止制冷剂气化后,体积迅速膨胀,流速急剧增加,因此,凸起段131b2与第三板片之间的距离较小,可以降低气体的流速,达到更好的换热效果。
换热器芯体11还可包括有至少一个第四板片114,第四板片114的结构大多数可参照第一板片111和第二板片112,第四板片114还包括第二阻挡部19b和第一孔口23,第四板片114的第一孔口23与第一板片111的第一孔口23、第二板片112的第一孔口23对齐形成第一孔道,换热器芯体11的第二孔道241被第四板片114的第二阻挡部19b分隔形成至少两个子孔道241a、241b。第三板片113和第四板片114位于换热器芯体中部区域或者说均离端板或底板一定距离设置,并将第一通道分隔为三个换热段,换热段包括第一换热段101、第二换热段102和第三 换热段103,第二换热段102位于第三板片113和第四板片114之间,如图中箭头所示,第一换热段101内流体流动方向与第二换热段102内流体流动方向相反,第二换热段102内流体流动方向与第三换热段103内流体流动方向相反,第一孔道的各子孔道通过第二孔道与相邻的子孔道连通,第二孔道的各子孔道通过第一孔道与相邻的子孔道连通。换热器芯体内部通过加设第三板片和第四板片,将第一通道分隔成至少三个换热段,使换热装置结构较小的情况下,有效地增长了流体的流动路径,保证换热装置出口的制冷剂的过热度满足一定要求,使其具有较好的换热性能。
第四板片114的第二阻挡部19b还开设有安装孔191,第三接管5的一端伸入至第二孔道中相对远离安装板13的子孔道110,第三接管5与第二阻挡部19b密封固定,以使第三接管5的第二接口与第二阻挡部的安装孔191相连通。第三接管5与第二阻挡部19b可以通过焊接等方式固定,以使第三接管5内流体与第二孔道邻近安装板的子孔道隔离。这种设置方式可以使第三接管和第四接管位于同一侧,可以通过一个压块固定。
当然,也可以如图12所示,将第三接管5设置在底板7上,此时则无需将第三接管5的一端伸入至第二孔道中。
也可以如图11所示,换热器包括第三板片113,此时换热器为两流程换热器。
本实施例的其他结构和特征与前述实施例相同或相近似,这里不再一一赘述。
以上实施例仅用于说明本发明而并非限制本发明所描述的技术方案,尽管本说明书参照上述的实施例对本发明已进行了详细的说明,但是,本领域的普通技术人员应当理解,所属技术领域的技术人员仍然可以对本发明进行修改或者等同替换,而一切不脱离本发明的精神和范围的技术方案及其改进,均应涵盖在本发明的权利要求范围内。
