具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
在本公开的描述中，除非另有明确的规定和限定，术语“第一”、“第二”仅用于描述的目的，而不能理解为指示或暗示相对重要性；除非另有规定或说明，术语“多个”是指两个或两个以上；术语“连接”、“固定”等均应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或一体地连接，或电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本公开中的具体含义。
本说明书的描述中，需要理解的是，本公开实施例所描述的“上”、“下”等方位词是以附图所示的角度来进行描述的，不应理解为对本公开实施例的限定。此外，在上下文中，还需要理解的是，当提到一个元件连接在另一个元件“上”或者“下”时，其不仅能够直接连接在另一个元件“上”或者“下”，也可以通过中间元件间接连接在另一个元件“上”或者“下”。
图1为本公开实施例提供的微通道换热器的立体图。参照图1，该微通道换热器100包括第一集流管101、第二集流管102、微通道扁管103、翅片104、进液管105和出液管106。微通道扁管103设置有多个，多个微通道扁管103沿第一集流管101、第二集流管102的长度延伸方向间隔排布，且多个微通道扁管103的两端分别与第一集流管101、第二集流管102连接。进液管105连接于第一集流管101，出液管106连接于第二集流管102，翅片104设置于相邻的两个微通道扁管103之间。
图2a至图2c为图1中微通道扁管的截面图。参照图2a至图2c，各微通道扁管103分别设有多个通道103a，各通道103a的长度沿微通道扁管103的长度延伸方向延伸，并贯通于微通道扁管103的两端面，且各通道103a沿微通道扁管103的宽度延伸方向(图中X方向)间隔排布，相邻两个通道103a间具有间隔部b。
换热器工作时，制冷剂在各个通道内流动，状态发生变化的同时进行换热，各通道103a的结构和尺寸对通道内制冷剂的变化会有影响。另一方面工作中的制冷剂可能是高温高压的状态，具有一定的压力，微通道扁管103需要具有一定的强度，确保制冷剂不泄露。
在一些实施例中，扁管的横截面为扁平状，高度方向(图中Y方向)上的两个侧面平行，通道的流通截面的形状为大体矩形，也可以是圆形或三角形等其他形状。一个扁管的各个通道流通截面的形状也可以不同，例如一部分为通道的流通截面为三角 形，一部分为矩形。在另外一些实施例中，扁管横截面为类扇形，高度方向上的两个侧面不平行，所包括的各个通道的尺寸也各不相同。
在上述的实施例中，间隔部的宽度可以是相同的，也可以是不同的。依照换热器使用的制冷剂要求和换热性能的要求，进行扁管通道和间隔物的结构和尺寸设计。
图3为本公开实施例提供的换热器加工方法的流程图。参照图3，该换热器加工方法包括：S13-S15。
S11、提供多个微通道扁管，并将多个微通道扁管沿第一方向间隔设置。
其中，微通道扁管包括沿其长度方向延伸的多个通道，各通道的两端分别贯通于微通道扁管的两端面，且各通道沿微通道扁管的宽度延伸方向排布，在微通道扁管宽度方向上相邻的两个通道之间具有间隔部。
S12、采样组件从初始位置出发，沿第一方向移动，依次采集各微通道扁管的特定信息，并将该特定信息传递给控制组件。
在一些实施例中，采样组件从初始位置沿着滑杆开始移动，初始位置可以是滑杆上对应微通道扁管排列方向上的第一个微通道扁管的位置或者是最后一个微通道扁管的对应位置，也可以是滑杆上对应特别指定的微通道扁管的位置，在此不做限定，沿微通道扁管的排列方向移动，微通道扁管的排列方向为第一方向，依次采集一个或者多个微通道扁管长度方向上的一个端面或者外周表面的特定信息(例如微通道扁管端面或外周表面的影像信息)，并将该特定信息传递给控制组件。其中，微通道扁管端面上的特定信息包括指定的一个或多个通道的宽度信息、指定的多个通道的宽度信息及排列顺序，指定的通道包括微通道扁管宽度方向上的第一通道或最后一个通道，或者微通道扁管宽度方向上的第一通道及最后一个通道。
在一些实施例中，采集各微通道扁管的特定信息包括下列方式中的一种或者多种的组合：
采集微通道扁管指定的一个或多个通道的截面积信息，其中，截面积信息是指通道的截面积大小和形状。
采集微通道扁管指定的多个通道的截面积信息和排列顺序，其中，截面积信息和排列顺序是指截面积大小和截面积大小的排列顺序。
采集微通道扁管指定的一个间隔部的信息，间隔部位于指定的两个通道之间，其中，间隔部信息是指间隔部的宽度。间隔部的宽度方向与微通道扁管的宽度方向、通道的宽度方向平行。
采集微通道扁管指定的多个间隔部的信息和排列顺序，其中，间隔部的信息和排列顺序是指间隔部的宽度及间隔部宽度数值大小的排列顺序。
采集微通道扁管指定的一个通道的高度信息，其中，高度信息是指高度的数值大小(通道在图中Y方向上的高度)。本公开实施例中的信息是指包含了参数和参数以外的所有信息。
S13、控制组件将特定信息与预存信息进行对比，并根据对比结果发出反馈信息。
具体地，控制组件将特定信息与预存信息进行对比，如果特定信息与预存信息不同，例如检测到的某一指定通道的截面面积与预存的指定通道的截面面积不同，则将该对比结果反馈给指示组件。其中，预存信息包括指定的一个或多个通道的宽度信息、截面积信息、高度信息或间隔部信息，或者指定的多个通道的宽度信息及排列顺序、截面积信息及排列顺序、间隔部信息及排列顺序。
S14、指示组件根据控制组件发出的反馈信息，给出指示信息。
S15、根据指示信息调整对应微通道扁管的位置。
具体地，根据反馈信息，如果采集的某一微通道扁管的特定信息与预存信息不一致，则采样组件停止在特定位置，特定位置如装错或装反的微通道扁管所在的位置，并通过指示组件发出指示信息，该指示信息为指示装错或装反微通道扁管，进一步的，该提示信息可以是通过光源或者警鸣声给出提示，以调整对应的微通道扁管的位置，在调整好对应的微通道扁管的位置之后，采样组件继续移动，再次采集一个或多个微通道扁管的特定信息，直到完成所有微通道扁管的信息采集及装错微通道扁管的调整。
举例说明，如果采样组件采集到微通道扁管宽度方向上的第一通道的宽度为L，则控制组件将该第一通道的宽度L与预存的对应微通道扁管的第一通道的宽度L'进行对比，若L＝L'，表示对应的微通道扁管安装正确，若L≠L'，表示对应的微通道扁管安装错误。或者，如果采样到微通道扁管宽度方向上的第一通道至第三通道的宽度分别为L1、L2和L3，则控制组件将该第一通道至第三通道的宽度与预存的对应微通道扁管的第一通道至第三通道的宽度L1'、L2'和L3'进行对比，若L1＝L1'、L2＝L2'、L3＝L3'，则表示对应的微通道扁管安装正确，否则为安装错误。
进一步地，根据指示信息调整对应的微通道扁管的位置包括，根据指示信息，沿第二方向移动微通道扁管，该第二方向与第一方向垂直或者成角度。
在本公开实施例中，指示组件与采样组件同步移动，可以理解，在其他实施例中，指示组件也可以与采样组件分别设置，且指示组件无需与采样组件同步移动。
图4为图3中步骤S12～S15的进一步具体流程图，参照图4，上述步骤S12～S15进一步包括：S101-S108。
S101、采样组件启动，沿第一方向移动。
S102、采集各微通道扁管的特定信息，并将该特定信息传递给控制组件。
S103、控制组件将特定信息与预存信息进行对比，以判断该特定信息与预存信息是否一致？若判断结果为是，进行步骤S104，若判断结果为否，进行步骤S106。
S104、采样组件继续移动。
其中，采样组件继续移动，并重复步骤S102。
S105、采样组件行程结束。
S106、采样组件停止移动。
S107、指示组件发出指示信息。
S108、调整装错或装反的微通道扁管。
其中，在调整了装错或装反的微通道扁管之后，继续重复步骤S101。
基于上述实施例的基础上，本公开实施例还提出了另一种换热器加工方法，本实施例与上述实施例的区别在于，在本实施例中，采样组件要采集完所有需要采集的微通道扁管的特定信息后，再将该特定信息传递给控制组件，由控制组件将采集到的所有微通道扁管的特定信息与预存信息进行对比，并根据对比结果给出反馈信息，使指示组件根据控制组件给出的反馈信息发出指示信息，进而根据指示信息调整所有装错或装反的微通道扁管。
在本实施例中，该换热器的加工方法包括步骤：S201-S205。
S201、采样组件启动，沿第一方向移动。
S202、依次采集完各微通道扁管的特定信息，并将采集到的所有微通道扁管的特定信息传递给控制组件。
S203、控制组件将特定信息与预存信息进行对比，并给出反馈信息。
S204、根据反馈信息，指示组件发出指示信息。
S205、根据指示信息，调整装错或装反的微通道扁管。
基于上述实施例的基础上，本公开实施例还提供了一种用于换热器的加工装置，该加工装置用于实现上述实施例的换热器加工方法。图4为本公开实施例提供的加工装置的结构示意图，参照图4，该加工装置包括支撑架1、安装组件2、采样组件3、控制组件(图中未示出)和指示组件(图中未示出)，安装组件2设于支撑架1的上部，以通过支撑架1支撑安装组件2，该安装组件2用于固定微通道扁管103，采样组件3用于采样各微通道扁管103的表面特定信息，控制组件与采样组件3、指示组件分别连接，用于将采样组件3采集到的各微通道扁管103的特定信息与预设信息进行对比，并根据对比结果给出反馈信息，使指示组件根据控制组件给出的反馈信息发出指示信息。
具体地，采样组件3能够沿微通道扁管103的排布方向往复移动，以采集微通道扁管103的周向表面或端面的特定信息，并将该特定信息传递给控制组件，控制组件在接收到采样组件3传递来的特定信息后，将该特定信息与预设信息进行对比，并根据对比结果发出反馈信息至指示组件，使指示组件根据控制组件传递来的反馈信息发出指示信息，例如指出装错或装反的微通道扁管。
进一步地，安装组件2包括滑杆21和梳齿件22，梳齿件22的长度延伸方向与第一方向(微通道扁管的排布方向)平行，且梳齿件22包括多个梳齿，多个梳齿沿第一方向间隔设置，用于固定微通道扁管103。滑杆21的长度延伸方向平于第一方向，采样组件3能够沿滑杆21往复移动。
以上所述，仅为本公开较佳的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应该以权利要求的保护范围为准。
