Description

冷凝器、冷凝器制作方法以及具有该冷凝器的制冷器具
【技术领域】
本发明涉及机械制造领域，且尤其涉及一种冷凝器、冷凝器制作方法以及具有该冷凝器的制冷器具。
【背景技术】
制冷器具，特别是家用电冰箱、冰柜或者酒柜等，通常采用一个主要包括压缩机、冷凝器、蒸发器等基本组件的封闭式制冷循环系统来实现对家用电器中储藏的食物的冷藏或冷冻；其中冷凝器的作用是将压缩机中流出的高温高压的气态制冷剂转换为温度较低的液态制冷剂。
为了防止在制冷器具的开口处发生凝露现象，现有技术在门的周围设置门防露装置。门防露装置可以通过在开口处的箱体内预埋加热丝形成，也可以设置门防露管，利用冷凝器中高温的制冷剂散发的热量防凝露。设置加热丝会额外增加制冷器具的功耗，而采用门防露管，若是门防露管直接连接压缩机后和冷凝器相连，则门防露管内的温度太高，会降低制冷器具的制冷效率，若是高温的制冷剂经过冷凝器冷凝后再流入门防露管，则有可能因温度较低而无法实现防露的功能。
【发明内容】
为了解决背景技术中的至少一个问题，本发明提出一种冷凝器、冷凝器制作方法以及具有该冷凝器的制冷器具。
为了实现上述目的，本发明提出一种制冷器具，包括压缩机、冷凝器和门防露管，所述冷凝器包括第一冷凝器和第二冷凝器，从所述压缩机流出的制冷剂依次通过所述第一冷凝器、门防露管和所述第二冷凝器，所述第一冷凝器和所述第二冷凝器均包括被卷曲成若干层的冷凝管且通过排列在所述冷凝管上的加热丝被固定在一起。
制冷剂在流过第一冷凝器后进入门防露管，相比于直接从压缩机流出的制冷剂的温度低，在满足制冷器具的门防凝露的前提下，可最大可能的减少冷气的损耗；虽然冷凝器包括第一冷凝器和第二冷凝器，但是冷凝器的整体的形状和体积没有发生太大的变化，不会额外增加冷凝器所需的放置的空间。
可选的，所述第一冷凝器和第二冷凝器固定于同一底座上。
可选的，所述第一冷凝器和所述第二冷凝器的长度比介于1：2和2：1之间，在此长度比的区间内调整，可以获得较佳的流经门防露管内的制冷剂的温度值。
可选的，所述第一冷凝器和所述第二冷凝器的长度相等。
可选的，所述门防露管的两端分别连接所述第一冷凝器的出口端和所述第二冷凝器的入口端。
可选的，被卷曲成若干层的冷凝管形成冷凝管阵列，所述冷凝管在冷凝管阵列的横向上呈螺旋状卷曲成圆形，所述散热丝在冷凝管阵列的纵向上平行延伸，冷凝管和散热丝的形状的配合可以使得散热效果更佳。
可选的，所述制冷器具为冰箱、酒柜或冰柜。
为了实现上述目的，本发明还提出一种冷凝器，该冷凝器包括第一冷凝器和第二冷凝器，所述第一冷凝器和所述第二冷凝器均包括被卷曲成若干层的冷凝管且通过排列在所述冷凝管上的加热丝被固定在一起。
虽然冷凝器包括第一冷凝器和第二冷凝器分，但是冷凝器的大致的形状和体积没有发生变化，不会增加冷凝器所需的放置的空间；第一冷凝器和第二冷凝器设置在一起，在第一冷凝器和第二冷凝器之间可以焊接其他的需要制冷剂的部件，例如门防露管，便于安装和使用。
可选的，所述第一冷凝器和第二冷凝器固定于同一底座上。
可选的，所述第一冷凝器和所述第二冷凝器的长度比介于1：2和2：1之间。
可选的，所述门防露管的两端分别连接所述第一冷凝器的出口端和所述第二冷凝器的入口端。
可选的，被卷曲成若干层的冷凝管形成冷凝管阵列，所述冷凝管在冷凝管阵列的横向上呈螺旋状卷曲成圆形，所述散热丝在冷凝管阵列的纵向上平行延伸。
为了实现上述目的，本发明还提出一种冷凝器的制作方法，包括以下步骤：将两段冷凝管分别卷曲成若干层形成第一冷凝器和第二冷凝器；通过冷凝管上排列的加热丝将所述第一冷凝器和所述第二冷凝器固定在一起。
可选的，将所述第一冷凝器和所述第二冷凝器固定在同一底座上。
本发明的构造以及它的其他发明目的及有益效果将会通过结合附图而对优选实施例的描述而更加明显易懂。
【附图说明】
以下附图仅对本发明做示意性说明和解释，并不限定本发明的范围，其中：
图1为本发明第一实施例的制冷循环的局部示意图。
图2为图1中的冷凝器组合中冷凝器的立体图。
图3为图2中冷凝器的冷凝管的展开示意图。
【具体实施方式】
为使本发明的目的、方案以及有益效果更加清楚明了，下面结合附图和优选实施例对本发明作进一步说明。
请参考图1，图1为本发明第一实施例的制冷循环的局部示意图，图1中的冷凝器10、20安装在一个制冷器具的制冷循环系统中，该制冷器具可以是家用电冰箱、冰柜或者酒柜等。该制冷循环系统包括一个设置在冷凝器10、20一侧且和冷凝器10、20相连的压缩机11以及和冷凝器10、20相连接的门防露管12。
冷凝器10、20由冷凝管和加热丝构成，冷凝管一般由金属铜制成，其首先被弯折排列在一个平面内，然后将金属散热丝30间隔一定距离并相互平行地焊接在冷凝管10、20的上方或下方，最后将附着有金属散热丝30的冷凝管10、20卷曲形成一个螺旋形的冷凝管阵列。冷凝管10、20在冷凝管阵列的横向上呈螺旋状卷曲成圆形，散热丝30在冷凝管阵列的纵向上平行延伸。
图3是冷凝管被弯折排列在一个平面内的示意图，图2是图3中位于一个平面内的冷凝管被卷曲形成一个螺旋形的冷凝管阵列的示意图，从图3可以看出，本实施例的冷凝管10、20包括两部分，分别为第一冷凝器10和第二冷凝器20，第一冷凝器10和第二冷凝器20固定在同一底座50上，冷凝管10、20的上方或者下方焊接有间距相等且平行排列的金属散热丝30，第一冷凝器10包括端口C和端口A，第二冷凝器20包括端口B和端口D。图2中，该冷凝器10、20阵列的体积和现有技术中的冷凝器10、20的体积几乎没有区别，外观上的区别在于该冷凝器10、20具有A、B、C、D四个端口，而现有技术中的冷凝器10、20仅具有一个出口和一个入口。
第一冷凝器10和第二冷凝器20不直接相连，在第一冷凝器10和第二冷凝器20之间连接门防露管12。图1中，第一冷凝器10的入口C连接压缩机11，第一冷凝器10的出口A连接门防露管12的入口F，门防露管12的入口E连接第二冷凝器20的入口B，第二冷凝器20的出口D和后面的比如毛细管、蒸发器相连。
从压缩机11中流出的高温制冷剂依次流过第一冷凝器10、门防露管12和第二冷凝器20，流入门防露管12中的制冷剂由于已经经过了第一冷凝器10的冷凝散热，因此温度要低于直接从压缩机11流出的制冷剂的温度，在满足防止冰箱门凝露的前提下，最小程度的降低冰箱的制冷效率。门防露管12内制冷剂的温度可以通过设置第一冷凝器10和第二冷凝器20的长度来设定，例如，若要使得门防露管12内制冷剂的温度高些，则缩短第一冷凝器10的长度，相反的，若要使得门防露管12内制冷剂的温度低些，则增长第一冷凝器10的长度，一般情况下，第一冷凝器10和第二冷凝器20的长度比的设定介于1：2和2：1之间，一个优选的实施例，第一冷凝器10的长度和第二冷凝器20的长度相等。
本发明还提出一种冷凝器的制作方法，包括以下步骤：将两段冷凝管分别卷曲成若干层形成第一冷凝器10和第二冷凝器20；通过冷凝管上排列的加热丝30将第一冷凝器10和第二冷凝器20固定在一起，之后将第一冷凝器10和第二冷凝器20固定在同一底座50上，以增加第一冷凝器10和第二冷凝器20的固定效果。
本实施例中的制冷循环系统是在冰箱中使用，此外，该制冷循环系统也适用于酒柜或冰柜。
