本发明提供一种吸入管的制作方法，将包含第一金属的吸入管与包含第二金属的毛细管隔着导热性为0.13W/m·K以上的粘弹性构件平行排列，将直线状的毛细管以及直线状的吸入管当中的一方固定，对另一方推压，以使毛细管与吸入管隔着粘弹性构件进行紧贴，以及以对吸入管与毛细管的周围进行覆盖的收缩管实施固定。

Description

吸入管的制作方法以及冰箱 技术领域
本发明涉及将吸入管(suction pipe)与毛细管进行固定的吸入管的制作方法以及具备吸入管和毛细管的冰箱。
背景技术
作为冰箱的构成部件的吸入管和毛细管以往通过焊接进行固定。然而，该固定方法中，在吸入管与毛细管为不同金属的情况下，由于电蚀，会在吸入管和毛细管发生腐蚀。
在专利文献1中，为了消除吸入管与毛细管的间隙，在吸入管上卷绕常温下具有可塑性且具有粘着性的板状的橡胶构件，并在该橡胶构件状上并行设置毛细管。进而公开了吸入管与毛细管不直接接触的如下构成：为了包围毛细管，盖上具有柔软性的隔热管，接着以设置于隔热管的周围的绑带来紧固隔热管。
专利文献1：JP特开昭57-58054号公报。
为了使吸入管与毛细管紧贴，需要隔热管和绑带。故而，构成部件变多。另外，工序要使绑带隔着隔热管以使橡胶变形而需要较强的力，因此吸入管的制作并不容易。
发明内容
本发明的目的在于，提供在吸入管与毛细管为不同金属的情况下不使用焊料的吸入管的制作方法。进而，本发明的目的在于提供耗时少且耗费劳力少的吸入管的制作方法。
另外，本发明的目的在于提供以少的构成部件来将吸入管和与之为不同金属的毛细管进行固定的冰箱。另外，本发明的目的在于，提供使吸入管与毛细管的热交换率得以提升的冰箱。
本发明的吸入管制作方法是具备包含第一金属的吸入管和包含与所述第一金属不同的第二金属的毛细管的吸入管的制作方法，其中，将直线状的所述吸入管与直线状的所述毛细管隔着导热性为0.13W/m·K以上的粘弹性构件平行排列，将所述直线状的毛细管以及所述直线状的吸入管当中的一方固定，采用安装于基体的辊对所述直线状的毛细管以及所述直线状的吸入管当中的另一方推压，使所述辊沿所述毛细管以及所述吸入管的长轴方向旋转，以使所述毛细管与所述吸入管隔着所述粘弹性构件进行紧贴，以及对收缩管实施固定，所述收缩管对所述吸入管与所述毛细管的周围进行覆盖。
通过使吸入管与毛细管隔着导热性为0.13W/m·K以上的粘弹性构件进行紧贴，从而能提供在吸入管与毛细管为不同金属的情况下不使用焊料的吸入管的制作方法。
另外，通过辊将粘弹性构件按压至直线状的吸入管和直线状的毛细管，并使辊直线状旋转，从而粘弹性构件在短时间容易变形。故而，能提供耗时少且耗费的劳力少的吸入管的制作方法。
另外，本发明中，多个所述毛细管隔着所述粘弹性构件与所述吸入管平行排列。
通过上述构成，即使存在多个毛细管，由于能同时将多个毛细管固定在吸入管上，因此也能在短时间内很容易地制作复杂的吸入管。另外，能提供使吸入管与毛细管的热交换率得以提升的冰箱。
另外，本发明中，所述粘弹性构件是丁基橡胶的橡胶板。丁基橡胶的橡胶板易变形，另外，形状不会恢复，因此吸入管与毛细管的紧贴性好。另外，丁基橡胶的橡胶板的导热性好，因此吸入管与毛细管之间的热交换率得以提升。
所述粘弹性构件是导热性热熔胶。导热性溶胶的导热性为0.65W/m·K以上。
另外，本发明中，所述第一金属包含铝，所述第二金属包含铜。
铝比铜廉价，因此通过使用铝，能降低成本。铝比铜轻，因此通过使用铝，能使部件轻量化。
本发明的冰箱具备：吸入管，其包含第一金属；毛细管，其包含与所述第一金属不同的第二金属；粘弹性构件，其夹在所述吸入管与所述毛细管之间，导热性为0.13W/m·K以上；以及收缩管，其对所述吸入管与所述毛细管的周围进行覆盖。
本发明与现有的通过焊接进行接合的构成相比，焊料变为粘弹性构件。因此，本发明能提供以与现有同样的构成部件来将吸入管和与之为不同的金属的毛细管进行固定的冰箱。
本发明的有益效果是：本发明能提供在吸入管与毛细管为不同金属的情况下，不使用焊料的吸入管的制作方法。进而，本发明能提供耗时少且耗费劳力少的吸入管的制作方法。
另外，本发明能提供以少的构成部件来将吸入管和与之为不同金属的毛细管进行固定的冰箱。另外，本发明能提供使吸入管与毛细管的热交换率得以提升的冰箱。

具体实施方式
以下，参照附图来说明用于实施本发明的各种实施方式。考虑到要点的说明或者理解的容易性，在不同附图中为了方便改变标号进行表示，但有的具备同一功能。虽然考虑到要点的说明或者理解的容易性而为了方便将实施方式分开表示，但不同实施方式所示的构成能进行局部的置换或者组合。虽然在实施方式2以后考虑到实施方式1和要点的说明或者理解的容易性，为了方便将实施方式分开表示，但不同实施方式所示的构成能进行局部的置换或者组合。
(第一实施方式)
图1是本发明的第一实施方式的经固定的吸入管与毛细管的剖视图。参照图1来说明本发明的经固定的吸入管与毛细管的第一实施方式。
如图1所示，第一实施方式中，吸入管101与毛细管103夹着作为粘弹性构件105的橡胶板而紧贴。吸入管101、毛细管103以及粘弹性构件105的周围通过被收缩管107覆盖且捆束在一起。
吸入管101由包含作为第一金属的铝的金属构成。铝比铜廉价，因此通过使用铝能降低成本。铝比铜轻，因此通过使用铝能使部件轻量化。
毛细管103由包含作为第二金属的铜的金属构成。铜的导热性高。由于吸入管101与毛细管103为不同金属，因此在接触时会发生电蚀。因此，无法将这些构件进行焊接。
为此，在吸入管101与毛细管103之间，夹入作为粘弹性构件105的橡胶板以使它们紧贴。粘弹性构件105使用导热性为0.13W/m·K以上的材料。
若粘弹性构件105的导热性为0.13W/m·K以上，则能进行吸入管101与毛细管103之间的热交换。粘弹性构件105优选使用丁基橡胶的橡胶板。
粘弹性构件105变形，来增加吸入管101与毛细管103的接触面积。如此，能提升吸入管101与毛细管103的热交换率。
收缩管107在保持粘弹性构件105的变形的同时将吸入管101与毛细管103进行固定。
本发明与现有的通过焊接来接合的构成相比，焊料变为粘弹性构件。因此，本发明能提供以与现有同样的构成部件来将吸入管和与之为不同的金属的毛细管进行固定的冰箱。
(第二实施方式)
图2是本发明的第二实施方式的经固定的吸入管与毛细管的剖视图。参照图2来说明本发明的经固定的吸入管与毛细管的第二实施方式。
第二实施方式与第一实施方式相比，在粘弹性构件205不是橡胶板而是导热性热熔胶这点上不同。如图2所示，第二实施方式中，吸入管201与毛细管203夹着作为粘弹性构件205的导热性热熔胶而紧贴。通过收缩管207对吸入管201、毛细管203以及粘弹性构件205的周围进行覆盖、捆束。
吸入管201、毛细管203、收缩管207与第一实施方式相同，因此省略重复的说明。
作为粘弹性构件205的导热性热熔胶在被加热而增加了流动性后，成为期望的形状而固形。在对吸入管201涂覆具有流动性的导热性热熔胶后，推压毛细管203。
导热性热熔胶绕行并附着于毛细管203的周围的一部分，因此导热性热熔胶与毛细管203之间的接触面积增加。如此，吸入管201与毛细管203的热交换率得以提升。
作为粘弹性构件205的导热性热熔胶的导热性可以为0.65W/m·K以上。导热性热熔胶的导热性还能设为比丁基橡胶的橡胶板高。
本发明与现有的通过焊接来接合的构成比较，焊料变为粘弹性构件。因此，本发明能提供以与现有同样的构成部件来将吸入管和与之为不同的金属的毛细管进行固定的冰箱。
(第三实施方式)
图3是本发明的第三实施方式的经固定的吸入管与毛细管的剖视图。参照图3来说明本发明的经固定的吸入管与毛细管的第三实施方式。
第三实施方式与第一实施方式相比，在设置第一毛细管303以外还设置第二毛细管309这点上不同。如图3所示，第三实施方式中，吸入管301与第一毛细管303以及第二毛细管309夹着作为粘弹性构件307的橡胶板进行紧贴。
通过收缩管305对吸入管301、第一毛细管303、第二毛细管309以及粘弹性构件307的周围进行覆盖、捆束。
吸入管301、粘弹性构件307的橡胶板、收缩管305与第一实施方式相同，因此省略重复的说明。
毛细管与吸入管相比直径更小。通过在第一毛细管303的基础上还设置第二毛细管309，能增加毛细管与吸入管301的接触面积，提升热交换率。
如此，毛细管能为多个。虽然在此示出了2根毛细管的例子，但毛细管也可以为3根。
本发明能提供使吸入管与毛细管的热交换率得以提升的冰箱。
(第四实施方式)
图4是本发明的第四实施方式的经固定的吸入管与毛细管的剖视图。参照图4来说明本发明的经固定的吸入管与毛细管的第四实施方式。
第四实施方式与第一实施方式相比，在同样地除了设置第一毛细管403还设置第二毛细管409、以及粘弹性构件407不是橡胶板而是导热性热熔胶的点上不同。如图4所示，第四实施方式中，吸入管401与第一毛细管403以及第二毛细管409夹着作为粘弹性构件407的导热性热熔胶进行紧贴。
通过收缩管405将吸入管401、第一毛细管403、第二毛细管409和粘弹性构件407的周围进行覆盖、捆束。
吸入管401、收缩管405与第一实施方式相同，因此省略重复的说明。另外，粘弹性构件407的导热性热熔胶与第二实施方式相同，因此省略重复的说明。
另外，第一毛细管403、第二毛细管409与第三实施方式相同，因此省略重复的说明。
导热性热熔胶能增加吸入管401与第一毛细管403以及第二毛细管409的接触面积。另外，导热性热熔胶的导热性能设为比丁基橡胶的橡胶板更高。
进而，通过在第一毛细管403的基础上还设置第二毛细管409，能增加毛细管与吸入管401的接触面积，能提升热交换率。
因此，本发明能提供使吸入管与毛细管的热交换率得以提升的冰箱。
(第一以及第二实施方式的吸入管的制作方法)
图5是表示用于本发明的辊的1个实施方式的概略图。图6是表示本发明的第一以及第二实施方式的吸入管的制作方法的示意图。参照图5以及图6来说明第一以及第二实施方式的吸入管的制作方法。
如图5所示，用于本发明的推压件501具备基体503、辊505和辊支承构件507。
基体503是具备作为单手握持的握持部的10cm至25cm的细长柄。细长柄使得辊505单向行进方便。基体503具有半圆径的截面，在握持时使得手心不会碰到拐角，从而即使加力，手也不会痛。
辊505由辊支承构件507支承，沿细长的基体503的长轴方向进行双向旋转。辊505通过双向旋转，能够实现往返。
如图6所示，将包含作为第一金属的铝的直线状的吸入管603与包含作为第二金属的铜的直线状的毛细管605隔着粘弹性构件607平行排列。
直线状的吸入管603以长轴方向平行地固定于作为规尺的直线状的台609之下，在其一部分可见的状态下，隔着粘弹性构件607以安装于基体的推压件601推压毛细管605。
虽然在此将作为一方的吸入管603固定并将作为另一方的毛细管605进行了推压，但也可以将毛细管605固定并将吸入管603进行推压。
使推压件601的辊沿着毛细管605以及吸入管603的长轴方向旋转，并使毛细管605与吸入管603隔着粘弹性构件607进行紧贴。推压件601的辊可以进行往返来提升吸入管与毛细管的紧贴性。推压件601示出了以手握持的例子，但也可以固定于机械并以一定的压力来进行推压。
如此，粘弹性构件607变形，来增加吸入管603与毛细管605的接触面积。粘弹性构件607是能长时间，至少至固定为止保证变形性的材质。在此，粘弹性构件607使用了橡胶板，尤其使用了丁基橡胶的橡胶板。粘弹性构件607还可以是导热性热熔胶。
其后，通过收缩管来对吸入管603和毛细管605的周围进行固定。进而，经固定的直线状的吸入管与毛细管一起被数次弯折为U字状并被加工成期望的形状后固定于冰箱。
本发明能提供在吸入管与毛细管为不同金属的情况下不使用焊料的吸入管的制作方法。进而，本发明能提供耗时少且耗费劳力少的吸入管的制作方法。进而，本发明能提供使吸入管与毛细管的热交换率得以提升的冰箱。
(第三以及第四实施方式的吸入管的制作方法)
图7是本发明的第三以及第四实施方式的吸入管的制作方法中的吸入管和毛细管的配置图。图8是表示本发明的第三以及第四实施方式的吸入管的制作方法的示意图。参照图7以及图8来说明第三以及第四实施方式的吸入管的制作方法。
第三以及第四实施方式的吸入管的制作方法在毛细管为多个这点上与第一以及第二实施方式的吸入管的制作方法不同。虽然在此示出了2根毛细管的例子，但毛细管也可以为3根以上。
如图7所示，将包含作为第一金属的铝的直线状的吸入管703、与包含作为第二金属的铜的直线状的第一毛细管705和第二毛细管707隔着粘弹性构件709而平行排列。
如图8所示，直线状的吸入管703以长轴方向平行地固定于作为规尺的直线状的台711之下，在其一部分可见的状态下通过粘弹性构件709来将第一毛细管705以及第二毛细管707相结合，并由安装于基体的辊701进行推压。
虽然在此将作为一方的吸入管703固定并将作为另一方的第一毛细管705与第二毛细管707进行推压，但也可以将第一毛细管705与第二毛细管固定并将吸入管703进行推压。
使辊701沿第一毛细管705、第二毛细管707以及吸入管703的长轴方向旋转，并使第一毛细管705、第二毛细管707和吸入管703隔着粘弹性构件709进行紧贴。辊701可以进行往返来提升吸入管与毛细管的紧贴性。辊701示出了以手握持的例子，但也可以固定于机械并以一定的压力来进行推压。
如此，粘弹性构件709变形，来增加吸入管703与第一毛细管705以及第二毛细管707的接触面积。
粘弹性构件709是能长时间，至少至固定为止能保持变形性的材质。粘弹性构件709使用橡胶板，尤其使用丁基橡胶的橡胶板。粘弹性构件709可以是导热性热熔胶。
其后，将吸入管703与第一毛细管705以及第二毛细管707的周围用收缩管进行固定。进而，经固定的直线状的吸入管与毛细管一起被数次弯折为U字状，在被加工为期望的形状后固定于冰箱。
本发明能提供在吸入管与毛细管为不同金属的情况下不使用焊料的吸入管的制作方法。进而，本发明能提供耗时少且耗费劳力少的吸入管的制作方法。进而，本发明能提供使吸入管与毛细管的热交换率得以提升的冰箱。
