Description

将塑料换热器的集管连接起来的方法
技术领域
本发明涉及将换热器的集管(Tube Header)和集箱(Header Tank)连接起来的方法，具体涉及将采用塑料材料制成的换热器的集管和集箱连接起来的方法，即根据热熔法(Thermal Fusing Method)将散热片管组件(Fin-tube Assembly)的散热片管单元(Fin-tube Unit)与集管连接起来，同时根据热熔法，使用超声波将散热片管单元与各集箱连接起来。
背景技术
图1示出了包括在常规制冷机中的蒸发器所用的换热器。如图1所示，换热器包括金属制冷剂管1，其包括制冷剂入口管段2和制冷剂出口管段3。散热片4沿制冷剂管1的长度，被设置在制冷剂管1的圆周上。左集管(未显示)和右集管6都采用金属制成，它们都被分别连接到由制冷剂管1构成的Z字形管结构的相对的两侧端。而且，除霜管7也被分别布置在Z字形管结构的相对的两侧端。
下文将对具有上述布置的常规换热器进行简要说明。
制冷剂通过与蒸发器入口相对应的制冷剂入口段2，被导入制冷剂管1。制冷剂途经在制冷剂管1中限定的Z字形制冷剂通道，然后到达制冷剂出口管段3。制冷剂在途经制冷剂管1时，经受蒸发过程。在蒸发过程中，制冷剂根据在潜热和显热之间的交换，进行热交换。然后，从制冷剂出口管段3出来的制冷剂被导入蓄热器8。蓄热器8起到制冷剂贮存箱的作用，它根据相关制冷机的周围环境应付负载变化，同时，它还起到汽水分离器(Moisture-liquid Separator)的作用。除霜管7必须定期除掉附着在蒸发器表面的冰霜。为此，针对除霜管7，使用电加热型加热器。每个散热片的顶部大体在一条线上与相关的一个除霜管7进行接触。
图2和3分别示出了包括在常规制冷机中的蒸发器所用的另一种换热器。所示的换热器是三管式蒸发器(Tri-tube Evaporator)，其中，制冷剂管、散热片和除霜管结合成整体。
如图2和3所示，散热片12沿金属制冷剂管11的长度，被设置在金属制冷剂管11的圆周上。除霜管13被设置在每个散热片12的圆周上。
制冷剂通过三管式蒸发器10的左端，被导入该蒸发器左端的蒸发器。制冷剂途经限定了Z字形制冷剂通道的三管式蒸发器10，然后通过布置在制冷剂管14出口的蓄热器15，从蒸发器出米。制冷剂管14与三管式蒸发器10的右端相连。
从上述说明中明显看出，常规散热片管式蒸发器具有的结构特点是，散热片12根据金属制冷剂管11的直径增大，与金属制冷剂管11相连。特别是，蓄热器15借助焊接与制冷剂管11的出口相连。为此，当开启和关闭制冷机时，产生噪声。并且，此类常规连接方法不能适用于本发明中所述的采用塑料材料制成的换热器。
发明内容
因此，本发明是鉴于上述问题而作出的，本发明的目的是提供一种将采用塑料材制制成的换热器的集管和集箱连接起来的方法，即通过使集管和集箱与散热片管组件的相关散热片管单元进行接触，并通过热熔机将集管和集箱紧贴住相关的散热片管单元，从而将集管和集箱与相关的散热片管单元热熔。
根据本发明的一方面，提供将塑料换热器的集管连接起来的方法，包括步骤：将塑料材料的散热片形成在塑料材料制成的制冷剂管的各自外圆周表面上，并以层叠方式布置，同时，可使各散热片能够与相关的邻近的一个制冷剂管相连，从而构成散热片管组件，该组件具有多个散热片管单元，每个散热片管单元均由一个制冷剂管和一个散热片组成；根据双注塑法(Double Injection Molding Process)，将采用塑料材料制成的集管分别设置在每个散热片管单元的相对的两端；布置热熔夹具(Thermal Fusing Jig)，以支撑位于散热片管组件各端的集管的各自底部；以及将热熔机的热熔压模(Thermal Fusing MoldingDie)紧贴住散热片管组件各端的散热片管单元，从而将集管热熔接到散热片管单元上，以使集管分别与散热片管单元构成整体。
每个热熔按压模均可具有倒三角形的横截面形状。
将集管热熔接到散热片管单元上的步骤可在下述条件下执行，即把集管和散热片管单元各自经受热熔接的部位保持在300℃～320℃的温度，直到集管和散热片管单元各自经受热熔接的部位显示出50％的厚度减少。
根据本发明的另一方面，提供一种将塑料换热器的集管连接起来的方法，包括步骤：将塑料材料的散热片形成在采用塑料制成的制冷剂管的各自外圆周表面上，并以层叠方式布置，同时，可使各散热片能够与相关的邻近的一个制冷剂管相连，从而构成散热片管组件，该组件具有多个散热片管单元，每个散热片管单元均由一个制冷剂管和一个散热片组成；根据双注塑法，将集管分别设置在每个散热片管单元的相对的两端；将采用塑料材料制成的集箱布置在散热片管组件的相对的两端，同时使各集箱与布置在散热片管组件相对的两端的相关的一端的集管进行接触；以及将发热装置布置在每个集箱上，并根据发热装置的工作，将集箱热熔接到布置在散热片管组件相关的一端的集管上。
发热装置可以是压电装置。
最好是，压电装置产生振动，该振动具有15000Hz的机械垂直振动能量，以及0.06～0.08mm的激励振幅(p-p：峰-峰值)。
本发明具有下列特点，即：换热器的各部件材料均为塑料材料，以及换热器的散热片和制冷剂管都根据塑料挤压法(Plastic ExtrusionProcess)被整体构成。根据这些特点，本发明提供一种将塑料换热器的集管连接起来的方法，即通过将集管与被挤压管的各自端部重叠，并向重叠部位施加热量。而且，本发明还提供一种根据热熔法使用超声波将集管与集箱连接起来的方法。

具体实施方式
图4示出了根据本发明的塑料换热器。参照图4，由标号112表示的塑料换热器包括多个制冷剂管114，这些制冷剂管采用塑料材料制成，并以叠层方式布置。采用塑料材料制成的散热片116按照下列方式被布置在邻近的制冷剂管114之间，即散热片116与相关的制冷剂管114构成整体。这样就形成散热片管组件。如图5所示，集管120被分别安装在各制冷剂管114的相对的两端的四周。左右集箱124和126被分别连接到位于散热片管组件的相对的两端的集管120上。
以下将对塑料换热器112的配置进行更详细说明。如图4所示，散热片116被设置在制冷剂管114的各自外表面上，同时相互之间隔开期望的距离。应注意，换热器的所有部件都采用塑料材料制成。如上所述，散热片116和制冷剂管114构成一体。因此，散热片管组件是一套散热片管单元，各单元均由一个制冷剂管114和一个散热片116组成。散热片管组件的各散热片管单元由标号118表示。
左集箱124与散热片管组件118的左端相连，而右集箱126与散热片管组件118的右端相连。制冷剂入口管130与右集箱126的下部相连。制冷剂出口管132与左集箱126的上部相连。
以下将参照图5，对集管120与散热片管组件的连接方法进行详细说明。将集管120与散热片管组件连接起来，这是根据双注塑法进行的。
通过使用双注塑法将集管120与散热片管组件连接起来所形成的接头显示出低强度。因此，通过热熔法，再次将各集管在其期望部位，例如上部(图5)，与相应的散热片管单元118的端部连接起来。根据热熔法，将集管120敷设在热熔夹具模136上，以使集管120由夹具模136牢固支撑。在这种状态下，使用热熔机128将每个散热片管单元118的上管端紧贴住相应的集管120。热熔机128配备了具有倒三角形形状的热熔压模134。
热熔压模134被布置成与散热片管组件的间距均匀的散热片管单元118对齐。当向热熔机128供电，同时将热熔机128紧贴住散热片管单元118的上端时，各散热片管单元118的上端因受热而膨胀，并与相应的集管120接触，这样散热片管单元118就被热熔接到集管120上。在图5中，标号138表示根据在各散热片管单元118和相应集管120之间进行热熔接所形成的接头。
集管120和散热片管单元118各自经受热熔接的部位被保持在300℃～320℃的温度，直到集管和散热片管单元各自经受热熔接的部位显示出50％的厚度减少。
以下对将散热片管单元118与每个集箱124和126连接进行详细说明。
参照图4和6，为了将散热片管单元118与每个集箱124和126连接起来，集管120被设置在各散热片管单元118的两端。如上所述，采用双注塑法，将集管120和散热片管单元118形成一个整体。
每个集箱124和126均被熔接到集管120上，集管120被设置在相应的一个散热片管组件处上。将集箱124和126与集管120熔接起来，这是根据图7和8中所示的方式进行的。
每个集箱124和126均具有多个隔壁133(图6)，这些隔壁从集箱的内顶部表面延伸。当每个集箱124和126将被熔接到相应集管120上时，它首先应按照下列方式定位，即如图7所示，每个隔壁133均与相邻一个集管120接触。在这种状态下，如图8所示，使用压电装置129，将机械振动能量施加到每个集箱124和126上。这样，根据超声波模压法(Ultrasonic Molding Process)，将每个集箱124和126与相应的集管120连接。
压电装置129将电能转换成15,000Hz的机械垂直振动能量，用于施加到每个集箱124和126上。在施加机械垂直振动能量的过程中，将每个集箱124和126与相应的集管120连接。在这种情况下，激励振幅为0.06～0.08mm(p-p：峰到峰值)。试样被摩擦热熔接，这在最多1秒内完成。
尽管为了说明性目的对本发明的优选实施例作了揭示，然而本领域技术人员将意识到，在不背离所附权利要求中揭示的本发明的范围和精神的情况下，可进行各种修改、添加和替代。
