背景技术
目前，中冷器的芯体基本由主板、外壳和多个芯片构成，芯体的各部件之间一般是通过钎焊焊接成整体，在进行焊接之前首先将各部件组装到一起，并将钎料填充在焊接面之间，焊接后，由于钎料融化，使芯体产生一定变形，而主板的形状一般不发生变化，这就使芯体与主板之间可能出现间隙，使中冷器在使用过程中可能在该间隙处出现漏气的情况。
发明内容

具体实施方式
下面将结合附图对本公开的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”和/或“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。此外，术语“第一”、“第二”和“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本公开的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”和“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的 普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
如图1至图23所示，本公开可选的实施例提供一种密封件300，用于热交换器，热交换器可以具有芯体100和主板200，主板200可以套装在芯体100上，并可以在芯体100与主板200之间形成连接缝500，密封件300可以包括主体，主体可以包括相互连接的第一连接部310和第二连接部320，第一连接部310可以配置成连接主板200，第二连接部320可以配置成连接芯体100，以使主体覆盖至少部分连接缝500。
本公开实施例所提供的密封件300、主板200与芯体100之间的连接缝500可以由主板200与芯体100之间的间隙形成，该间隙可在钎焊后由钎料填满，也可在采用粘接物质粘接主板200和芯体100时由粘接物质填满，或者该间隙大小为零，使连接缝500为一条直线，当主板200与芯体100之间形成漏气的间隙时，该漏气的间隙也为连接缝500的一种；本公开实施例中，密封件300可采用熔点高于或等于热交换器的其他部件的材料制造，例如采用铝、铜或钢材等，也可采用熔点较低的橡胶或树脂等材料制造，当采用熔点较低的材料制造时，可使密封件300在钎焊过程中产生一定的融化并流入连接缝500并与连接缝500连为一体；密封件300可为条状结构，密封件的横截面可为楔形，密封件300的横截面也可为L形或者V形的结构；采用本公开实施例所提供的密封件300的热交换器具有室体时，密封件300可安装在主板200背离室体的一侧，该室体可以安装于该主板200；当然，也可使该密封件300安装于该主板200面向该室体的一侧。
本公开实施例所提供的密封件300可以与热交换器的芯体100和主板200连接，并可以覆盖至少部分连接缝500，当在该部分被密封件300覆盖的连接缝500处出现间隙，并在该间隙处出现漏气的情况时，密封件300可对漏出的气流产生一定阻挡，进而缓解在该间隙处漏气的问题。
如图2、图3和图8所示，可选地，主板200具有过渡圆角220，过渡圆角220可以位于主板200靠近芯体100的位置，芯体100可以包括插入部340，插入部340可以配置成插入过渡圆角220与芯体100之间形成的间隙600。在主板200成型的过程中，由于钣金折弯工艺的限制，主板200不可避免的在弯折处出现过渡圆角220，当密封件300覆盖连接缝500时，气流可能会沿过渡圆角220与芯体100之间的间隙600流出，使对主板200与芯体100之间的密封无法达到较理想效果，而本公开实施例中，通过设计该插入部340，并将插入部340插入过渡圆角220与芯体100之间形成的间隙600，则能通过插入部340对过渡圆角220形成的路径进行阻挡，进而更有效的缓解主板200与芯体100之间漏气的问题。本公开实施例中插入部340可以为独立于主体的部分，插入部340可以连接于主体，可以不与主体连接，而仅与主体接触，或不接触，进而可以通过插入部340和主体形成对气流的双重阻挡；也可使主体即为该插入部340，并使第一连接部310和第二连接部320均为该插入部340的一部分，例如可以使第一连接部310为插入部340的一个面,第二连接部320为插入部340的另一个面。
可选地，插入部340可以连接于主体。相对于插入部340与主体仅接触而不连接或二者不接触的情况，使插入部340与主体连接使密封件300整体性更好，避免气流从插入部340与主体之间可能存在的间隙流出，而且，在拆装密封件300时，可将密封件300作为整体进行操作，可提高热交换器的装配效率。
可选地，插入部340的一端为连接于主体的连接端，插入部340的另一端为游离端；
游离端与连接端的连线可以垂直于第一方向，或者，游离端与连接端的连线可以相对于第一方向倾斜；
第一方向为主体的长度方向。
本公开实施例中，主板200可以具有方形的框结构，主体的长度方向即为主体沿着该方形的框结构的一个边延伸的方向。
可选地，插入部340在密封件300的横截面内的投影为从连接端到游离端逐渐收缩的楔形。主板200的过渡圆角220可以与芯体100之间形成类似三角形或楔形的间隙，而使插入部340在密封件300的横截面内的投影为楔形，则能使插入部340适配于过渡圆角220与芯体100之间的间隙，进而起到较好的封堵效果。
可选地，插入部340连接于第一连接部310与第二连接部320的交接处。
具体地，本公开实施例中可使在密封件300的横截面内第一连接部310、第二连接部320与插入部340形成三个向不同方向伸出的肢端。
芯体100一般具有两个主板200，为了采用一个密封件300对两个主板200与芯体100之间的间隙600均产生一定密封效果，可选地，第二连接部320具有配置成与芯体100贴合的第一贴合面322，主体可以包括两个第一连接部310，两个第一连接部310在第二方向上对称的设置在第二连接部320的两侧，第二方向垂直于第一连接部310的长度方向，且第二方向和第一连接部310的长度方向均基本上平行于第一贴合面322。这使得两个第一连接部310能够分别连接于两个主板200，进而可以使同一个密封件300能够对两个主板200与芯体100之间的间隙产生一定密封效果。
可选地，当密封件300在安装时，为了使同一密封件300能够对两个主板200与芯体100之间的间隙均产生一定密封效果，第二连接部320通常需延伸至两个主板200处，这就导致第二连接部320具有一定的体积和刚度，安装时不易根据实际装配情况产生所需要的形变，造成安装较困难，甚至有时导致无法完 成装配。本公开实施例中，可选地，在第二连接部320上可以形成有开口321，以减小第二连接部320的刚性。这样，在安装密封件300时，可根据安装空间使密封件300产生一定形变，使密封件300进入配置成安装该密封件300的空间，并使密封件300能够通过形变适应安装位置，降低密封件300的安装难度。
可选地，在第二连接部320上可以形成有通孔，通孔可以供连接于芯体100的管路贯穿。芯体100上一般连接有供介质进入芯体100的管路，通过该通孔使芯体100的安装有管路的一侧，也能够安装密封件300，使热交换器漏气的问题得到进一步的缓解。
如图8所示，可选地，第二连接部320可以具有配置成与芯体100贴合的第一贴合面322，插入部340可以具有配置成与芯体100贴合的第二贴合面，第二贴合面与第一贴合面322在同一平面内。这使得密封件300与芯体100贴合紧密，使气流难以从插入部340与主体之间流出，进而提高密封件300阻挡气流的效果。
可选地，插入部340可以具有配置成与过渡圆角220贴合的弧形贴合面。这使得弧形贴合面与过渡圆角220更适配，贴合较紧密，降低气流从主板200与插入部340之间流出的可能。
可选地，在第一方向上主体的两端中至少一者可以连接有插入部340，第一方向为主体的长度方向。如图1所示，在第一方向上主体的两端均连接有插入部。当主板200的过渡圆角220、芯体100与主体之间形成气流的流通通道时，通过插入部340将该通道的两端或一端堵塞，就能够对流入该通道内的气流产生一定封堵。当然，也可使插入部340沿着主体的长度方向延伸，使插入部340填充在整个上述通道内，但仅是插入部340将该通道的两端堵塞，在对流入该通道内的气流产生一定封堵的情况下更节省材料，能够降低制造成本。
可选地，在第一方向上主体的两端中至少一者可以形成弯折部330，弯折部330向第三方向弯折，第二连接部320可以具有配置成与芯体100贴合的第一贴合面322，第三方向垂直于该第一贴合面322。在制造主板200时，主板200的方形框的四个角的位置本应形成直角，但由于钣金折弯工艺的限制，该四个角也难以避免的会产生圆角210，当采用密封件300仅阻挡在主板200的方形框的某一个边处可能出现的漏气时，由于该圆角210阻挡的原因，如果密封件300仅为直线延伸件，难以将方形框的该边两端的圆角210覆盖，进而难以阻挡从该圆角210处产生的漏气。而采用本公开实施例所提供的弯折部330去适应方形框上的圆角210，使弯折部330覆盖该圆角210，使在热交换器在该圆角210处可能出现的漏气也得到阻挡，进而缓解热交换器在主板200与芯体100连接处漏气的问题。
可选地，插入部340可以形成于弯折部330。当主体覆盖主板200的方形框的某一个边以及该边两端的圆角210时，主板200的上述过渡圆角220、芯体100及弯折部330之间的空间，在方形框的圆角210的位置会形成弧形的气流通道，而将插入部340设置在该弯折部330则能对可能从该弧形的气流通道流出的气体进行阻挡，进而缓解热交换器在主板200与芯体100连接处漏气的问题。
当热交换器的芯体100包括多个芯片时，在热交换器进行钎焊时，各芯片一般是在竖向方向上堆叠，当芯体100具有外壳时，在芯片的堆叠方向上外壳与芯片之间也添加焊料，在钎焊过程中，随着钎料的融化，相邻芯片之间以及芯片与外壳之间的距离逐渐减小，进而导致芯体100的高度减小，但由于主板200的尺寸一般不发生变化，当焊接过程结束后，就可能因芯体100的高度减小导致在芯体100与芯体100上方的部分主板200之间产生间隙。而在本公开实施例中，可选地，芯体100可以包括多个芯片，在各芯片的堆叠方向上密封件300配置成至少安装在芯体100的一侧。这样，如果在芯片的堆叠方向上密封件300仅安装在芯体100的一侧，则在进行钎焊时，可使芯体100安装有密封件300的这一侧位于上方，在钎焊完成后，即使在主板200与芯体100之间形成漏气的间隙，也可通过密封件300至少缓解漏气的问题；而当在芯片的堆叠方向上芯体100的两侧均安装有密封件300，则在进行钎焊时，该两侧中任意一侧均可以位于上方，同样可通过密封件300至少缓解漏气的问题。
可选地，密封件300为一体成型的方形框，方形框可以配置成套装在芯体100上。主体覆盖连接缝500，当密封件300为方形框并套装在芯体100上时，主体可以基本覆盖相应主板200与芯体100之间全部的连接缝500，进而使得在该主板200与芯体100之间的连接缝的任意位置处出现的漏气问题基本都可以得到适量缓解；另外，即使在主板200的过渡圆角220、芯体100以及密封件300之间形成气流通道，该通道也是沿芯体100外围延伸的闭合的通道，气流难以从该通道流出，进而避免了专门采用插入部340密封该气流通道带来的不便和成本。
如图11至图16所示，本公开的可选的实施例提供一种密封组件，可以包括U形框400和本公开的可选实施例所提供的密封件300，U形框400可以具有相互连接的第三连接部410和第四连接部420，第三连接部410可以配置成连接主板200，第四连接部420可以配置成连接芯体100，U形框400与密封件300连接，以形成可以配置成套装在芯体100上的方形框，方形框可以配置成套装在芯体100上并覆盖连接缝500。
本公开实施例所提供的密封组件，采用了本公开实施例所提供的密封件300，并且通过U形框400连接形成套装在芯体100上的方形框，该密封组件可以基本覆盖相应主板200与芯体100之间的全部连接缝，进而使该主板200与芯体100之间的连接缝的任意位置处出现的漏气问题基本都可以得到适量缓解；而且， 如果密封件300与U形框400一体成型，安装该密封组件时，当将密封组件安装于主板200背离与其连接的室体的一侧时，必须在安装主板200之前先将密封组件套装在芯体100上，限制了热交换器的组装流程从而使得装配工艺安排受限且容易导致装配错误，而使密封组件可以包括密封件300和U形框400两个独立的部件，在装配该密封组件时，密封件300和U形框400可分别安装，因此密封组件无需再安装主板200之前进行安装，使热交换器的装配流程更加灵活，可根据情况适当调整密封组件的装配顺序；而且，由于密封组件包括密封件300和U形框400两个独立的部件，在装配过程中可以适当调整密封件300与U形框400之间的相对位置，或者单独调整U形框400与芯体100和主板200之间的相对位置、单独调整密封件300与芯体100和主板200之间的相对位置，即，在装配过程中可以根据需要选择密封件300和U形框400的位置，使密封组件封堵主板200与芯体100之间泄露的气流的效果尽可能优化。
可选地，第二连接部320具有配置成与芯体100贴合的第一贴合面322，主体可以包括两个第一连接部310，在第二方向上两个第一连接部310对称的设置在第二连接部320的两侧；
U形框400可以包括两个第三连接部410，两个第三连接部410在第二方向上对称的设置在第四连接部420的两侧。
第二方向垂直于第一连接部310的长度方向，且第二方向和第一连接部310的长度方向均基本上平行于第一贴合面322。
具有主板200的热交换器一般可以具有两个主板200，两个主板200与芯体100之间均形成有连接缝500，本公开实施例中，密封件300可以具有两个第一连接部310，U形框400可以具有两个第三连接部410，使得采用一个密封组件能够基本覆盖两个主板200与芯体100之间形成的连接缝500，这种情况相对于在每个主板200与芯体100之间形成的连接缝500处均单独设置一个密封组件，减少了部件的个数，进而减少了安装步骤，提高了装配效率，且更易存储，不易丢失。
可选地，主体可以包括两个第五连接部350，在第一连接部310的长度方向上第二连接部320的两端均连接有第五连接部350，在第二方向上第五连接部350的一端连接于两个第一连接部310中的一个，第五连接部350的另一端连接于两个第一连接部310中的另一个；
可选地，第四连接部420与第五连接部350连接，且第四连接部420覆盖第二连接部320与芯体100之间的连接缝。
本公开实施例中，第二连接部320与芯体100之间的连接缝的形式，可采用主板200与芯体100之间的连接缝500的形式。在生产密封件300和U形框400时，由于钣金折弯工艺的限制，在第一连接部310与第二连接部320的交接处、在第三连接部410与第四连接部420的交接处，以及在第五连接部350与第二连接部320的交接处均不可避免的形成过渡圆角，当第四连接部420连接于第五连接部350时，在第五连接部350的过渡圆角与第五连接部350之间的间隙形成气流通道，使第四连接部420覆盖第二连接部320与芯体100之间的连接缝500，则使第四连接部420在第二方向上从一个主板200延伸到另一个主板200，相应的，第五连接部350的过渡圆角与第四连接部420之间的间隙形成气流通道也基本是从一个主板200延伸至另一个主板200，泄露气流沿着该气流通道的流通会受到该泄露气流流动方向上的主板200的阻挡，进而在一定程度上阻碍泄露气流流动，从而可以减小甚至基本消除泄露气流的出现，从而缓解甚至基本消除从在主板200与芯体100之间漏气的问题。
如图12所示，可选地，第一连接部310与第五连接部350基本上垂直相交并形成第一直角部360；
在第三连接部410与第四连接部420的交接处形成有第二直角部430，第二直角部430位于第四连接部420与第五连接部350重叠处，以使第一直角部360可以与第二直角部430密封连接，且第一直角部360可以与第二直角部430均配置成与主板200密封连接。
由于钣金折弯工艺的限制，在密封件300和U形框400成型后，第一连接部310与第五连接部350之间，以及第三连接部410与第四连接部420之间一般也应形成过渡圆角，假设第一连接部310与第五连接部350之间形成第一圆角，第三连接部410与第四连接部420之间形成第二圆角，则当第四连接部420与第五连接部350连接时，在第一圆角与第二圆角相交的位置处，第一圆角与第二圆角无法紧密贴合，第一圆角、第二圆角与主板200之间也无法紧密贴合，就会产生间隙，在主板200与芯体100之间泄露的气流就会从该间隙流出。采用第一直角部360和第二直角部430能够基本填充在第一圆角、第二圆角与主板200之间形成的间隙，使气流难以冲该间隙处流出，进一步缓解从在主板200与芯体100之间漏气的问题。
如图13和图14所示，可选地，第五连接部350与第四连接部420之间通过定位销351和定位孔421进行定位配合。在装配密封组件时，通过定位销351与定位孔421之间的配合对密封件300与U形框400之间的相对位置进行预定位，使焊接过程中密封件300与U形框400之间的位置相对稳定，进而提高密封件300与U形框400之间的连接精度，保证密封性较好，进一步缓解从在主板200与芯体100之间漏气的问题。
可选地，定位销351在第一连接部310的长度方向上延伸，定位孔421在第三方向上的尺寸大于定位销351横截面的直径尺寸，第二连接部320可以具有配置成与芯体100贴合的第一贴合面322，第三方向基 本上垂直于该第一贴合面322。可选地，定位孔421的尺寸大于定位销351的横截面尺寸，则能在一侧第五连接部350处的定位孔421与定位销351配合后留出适当装配余量，使另一侧的第五连接部350的定位孔421与定位销351较容易地配合，而使定位孔421在第三方向上的尺寸大于定位销351横截面的直径尺寸，则在钎焊过程中将密封件300放置于芯体100的上方，密封件300处于重力的作用下，通过芯体100限定密封件300与U形框400在竖向方向上的相对位置，使在钎焊过程中密封件300不易相对U形框400移动，密封件300与U形框400之间仍能具有较高的连接精度，保证密封性较好，进一步缓解从在主板200与芯体100之间漏气的问题。
在本公开实施例中，可在第四连接部420上形成供管路贯穿的通孔。
如图17至图23所示，本公开可选的实施例提供一种密封组件，该密封组件可以包括芯体100的外壳110和本公开实施例所提供的密封件300，在外壳110上可以形成有密封部111，密封部111可以配置成密封主体、外壳110与主板200之间形成的间隙。
在主板200成型的过程中，由于钣金折弯工艺的限制，主板200不可避免的在弯折处出现过渡圆角220，当密封件300覆盖连接缝500时，气流可能会沿过渡圆角220与芯体100之间的间隙600流出，使得主板200与芯体100之间的密封无法达到较理想效果。
本公开实施例所提供的密封组件，通过采用外壳110上的密封部111填充至少部分主体、外壳110与主板200之间形成的间隙，覆盖该间隙的横截面以阻断进入该间隙的气流的流动，进而缓解主板200与芯体100之间漏气的问题。
本公开实施例中，密封部111可为板件或块状等结构，也可为硬质或具有一定弹性的结构。
可选地，密封部111可以具有弧形面111a，弧形面111a可以配置成与主板200的过渡圆角220贴合。这使得密封部111能够通过弧形面111a与过渡圆角220适配，降低气流从密封部111与主板200之间泄露的可能，进一步缓解主板200与芯体100之间漏气的问题。
可选地，在密封件的主体上可以形成有容纳部331，容纳部331可以与密封部111卡接或插接。通过密封部111与容纳部331卡接或插接，使密封部111与主体之间有部分重叠，进而使气流难以从密封部111与主体之间流出；同时，容纳部331可以与密封部111卡接或插接，也有对外壳110与主板200之间的位置关系进行定位的作用，进而有对外壳110、密封件300和主板200三者之间的位置关系进行定位的作用。
可选地，在第一方向上外壳110的两侧中的至少一侧可以形成有密封部111，且在第一方向上主体的至少一端形成弯折部330，容纳部331可以形成于弯折部330，第一方向为主体的长度方向。如上文内容可知，由于钣金折弯工艺的限制，上述四个部分处的角也难以避免的被形成为圆角210，如果密封件300仅为直线延伸件，难以将方形框的圆角210覆盖。而采用本公开实施例所提供的弯折部330去适应方形框上的圆角210，使弯折部330覆盖该圆角210，使在热交换器在该圆角210处可能出现的漏气也得到阻挡，进而缓解热交换器在主板200与芯体100连接处漏气的问题。
本公开的可选的实施例提供一种热交换器，该热交换器包括本公开实施例所提供的密封件300；或者，该热交换器包括本公开实施例所提供的密封组件。也就是说，在本公开实施例中，热交换器可采用密封件300，而该密封件300并未应用于本公开实施例所提供的密封组件；或者，热交换器采用本公开实施例所提供的密封组件，也就相应的采用了密封组件中的密封件300。
本公开实施例所提供的热交换器，采用了本公开实施例所提供的密封件300，密封件300可以与热交换器的芯体100和主板200连接，并覆盖至少部分连接缝500，当在该部分被密封件300覆盖的连接缝500处出现间隙，并在该间隙处出现漏气的情况时，密封件300可对漏出的气流产生一定阻挡，进而缓解在该间隙处漏气的问题。
最后应说明的是：以上各实施例仅用以说明本公开的技术方案，而非对其限制；尽管参照前述各实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本公开各实施例技术方案的范围。
工业实用性：
本公开实施例中，通过设计该插入部，并将插入部插入所述过渡圆角与所述芯体之间形成的间隙，则能通过插入部对过渡圆角形成的路径进行阻挡，进而更有效的缓解主板与芯体之间漏气的问题；在本公开实施例中，芯体上一般连接有供介质进入芯体的管路，通过该通孔使芯体的安装有管路的一侧，也能够安装密封件，使热交换器漏气的问题得到进一步的缓解；在本公开实施例中，使得密封件与芯体贴合紧密，使气流难以从插入部与主体之间流出，进而提高密封件阻挡气流的效果；本公开所提供的密封件、密封组件及热交换器，密封件与热交换器的芯体和主板连接，并覆盖至少部分连接缝，当在该部分被密封件覆盖的连接缝处出现间隙，并在该间隙处出现漏气的情况时，密封件可对漏出的气流产生一定阻挡，进而缓解在该间隙处漏气的问题。
