Description

冷凝器以及具有它的冰箱 技术领域
本发明涉及制冷技术领域，具体而言，涉及一种冷凝器以及具有它的冰箱。
背景技术
目前，目前冰箱制冷***通常采用以下两种结构的冷凝器进行散热：
1、将冷凝管道粘贴在冰箱外壳内壁，通过冰箱金属外壳传热、散热。采用该结构，由于冷凝管贴覆在冰箱外壳内表面，会造成冰箱表面温度高，导致冰箱外壳与内胆的温差增加，增加了冰箱外壳向冰箱内热量传递的速度，严重影响箱体保温性能；同时为了增加散热效果，需要增长冷凝管长度，增加成本。
2、将片状冷凝器紧固在冰箱背面，通过环境空气自然冷却散发热量，达到制冷目的。采用该结构，片状冷凝器固定在冷箱背部，不仅影响冰箱的美观性，而且冷凝器的散热面积小且仅采用自然散热方式散热，冷却效率不高，影响产品性能。
3、将片状冷凝器设置在冰箱的压缩机舱内。由于片状冷凝器的散热面积小，送风装置距离冷凝器有一段距离，送风装置的尺寸受压缩机舱空间大小的限制，容易导致散热效果差且不适用于多种规格的冰箱。
因此，急需一种散热效果好、布置紧凑合理的冷凝器。

下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同 或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参照图1至图14详细描述根据本发明实施例的冷凝器100。
如图1所示，根据本发明第一方面实施例的冷凝器100包括：风管10、送风装置20以及冷凝件30。风管10内限定出风道11，送风装置20与风管10固定连接，冷凝件30具有制冷剂进口a和制冷剂出口b，冷凝件30至少部分地位于风道11内。
根据本发明第一方面实施例的冷凝器100，通过将送风装置20、风管10以及制冷件集成在一起，利用送风装置20对风道11进行强制通风，以使外界空气规律地进入风道11内与位于风道11内的冷凝件30热交换，便于冷凝件30热量的快速、均匀散发，显著增强冷凝器100的散热效果；而且冷凝器100整体布置更紧凑合理、适用于多种规格的冰箱。
可以理解，制冷剂进口a用于通入高温高压的气态制冷剂，气态制冷剂流经冷凝件30并向外界空气散热，以转化成液态制冷剂从制冷剂出口b流出。具体地，送风装置20可以是风扇，风管10的两端均敞开以使外界空气在送风装置20的作用下进出风道11。
根据本发明的一些实施例，如图2和图3所示，冷凝件30包括多个沿风管10的轴向依次分布且互相连通的第一冷凝管段31，每个第一冷凝管段31由第一冷凝管螺旋地形成，且每个第一冷凝管段31的螺旋线位于同一环面上。其中，环面是指圆或椭圆绕与其不相交的直线环绕一圈所形成的旋转面。第一冷凝管段31的螺旋线为第一冷凝管的螺旋轨迹线。
具体而言，多个第一冷凝管段31所在的环面在风道11内自风管10的一端向另一端依次分布。每个第一冷凝管段31与其它的第一冷凝管段31中的至少一个连通以使制冷剂能够流经每个第一冷凝管段31。
由此，每个第一冷凝管段31的螺旋线位于同一环面，从而使每个第一冷凝管段31的第一冷凝管与风道11内气流的流动方向大体一致(风道11内气流的流动方向呈由风管10中心向四周辐射)，这样在风道11内的气流由风管10一端向另一端流动时能够充分地与各个第一冷凝管段31接触，增大了换热面积，具有更好的散热效果。此外，多个第一冷凝管段31在轴向上逐层分布，以实现逐层换热，换热效率更高。
如图4和图5所示，每个第一冷凝管段31的内侧位于同一内圆环311上且外侧位于同一外圆环312上，多个第一冷凝管段31的内圆环311同轴设置且多个第一冷凝管段31的外圆环312同轴设置。由此，使气流在风道11内的流动更均匀，进而使其与第一冷凝管段31的换热更均匀。
如图6所示，相邻的第一冷凝管段31的环绕中心313同轴设置且两者的环绕中心313的直径不同。第一冷凝管段31的个数为两个以上时，每个第一冷凝管段31和与之次邻接的第一冷凝管段31的环绕中心313的直径相同。其中，第一冷凝管段31的环绕中心313是指第一冷 凝管段31的螺旋线所在的环面的中心轴线。由此，使气流与各个第一冷凝管段31的接触更充分，提高了换热效果。
本领域技术人员可以理解，本发明并不限于此，在另一些实施例中，多个第一冷凝管段31的环绕中心313的直径可以相同。
为增强每个第一冷凝管段31与风道11内气流的充分换热，风管10的内径可以大于外圆环312的直径。这样，风管10的内壁与每个第一冷凝管段31之间形成间隙，避免了第一冷凝管段31与风管10直接接触造成的接触处不能充分换热的现象发生。
作为优选实施方式，参照图4和图6所示，冷凝件30还包括与多个第一冷凝管段31中的至少一个相连通的第二冷凝管段32，第二冷凝管段32位于多个第一冷凝管段31的内侧。具体地，第二冷凝管段32位于多个第一冷凝管段31的内圆环311内侧，第二冷凝管段32的顶端可以与最上方的第一冷凝管段31的顶端相平齐，第二冷凝管段32的底端可以与最下方的第一冷凝管段31的底端相平齐。
由此，增设的第二冷凝管段32合理利用了每个第一冷凝管段31内部的空间，提高了冷凝器100的有效换热面积，具有更好的散热效果。
在一些实施例中，第二冷凝管段32由第二冷凝管螺旋地环绕风管10的中心轴线形成。由此，第二冷凝管段32采用上述结构，使风道11中部的气流(风道11中部的气流大体沿风管10的轴向流动)大体垂直的与第二冷凝器100管的管壁接触，这样使第二冷凝管段32处的散热效果更好，避免了热量在第二冷凝管段32处的聚集。
根据本发明的一些实施例，第二冷凝管段32与多个第一冷凝管段31依次连接，制冷剂进口a形成在第二冷凝管段32上且制冷剂出口b形成在多个第一冷凝管段31中的一个上。根据本发明的另一些实施例，第二冷凝管段32与多个第一冷凝管段31依次连接，制冷剂出口b形成在第二冷凝管段32上且制冷剂进口a形成在多个第一冷凝管段31中的一个上。
也就是说，第二冷凝管段32以及多个第一冷凝管段31依次连接，制冷剂依次流经各个冷凝管段。由此，制冷剂在第一冷凝管以及第二冷凝管内单向流动。冷凝器100的换热效果更好。
在一个具体实施例中，第二冷凝管段32的上端与最上方的第一冷凝管段31相连接，上方的第一冷凝管段31与相邻的下方的第一冷凝管段31相连接，制冷剂进口a形成在第二冷凝管段32和最下方的第一冷凝管段31中的一个上，且制冷剂出口b形成在第二冷凝管段32和最下方的第一冷凝管段31中的另一个上。这样，制冷剂的大致流动趋势为先内部后外部(或者先外部或内部)，散热效果更好。
本领域技术人员可以理解，冷凝件30的管路弯曲形状不限于上述实施例中第一冷凝管段31以及第二冷凝管段32的环绕形状。例如，根据本发明的另一些实施例，如图7所示，冷 凝件30包括多个自外向内依次套设的第三冷凝管段33，相邻的两个第三冷凝管段33彼此连通，每个第三冷凝管段33由第三冷凝管螺旋地环绕风管10的中心轴线形成。
进一步地，如图8至图10所示，每个第三冷凝管段33的螺旋线大***于同一圆柱面上，第三冷凝管段33的个数为两个以上时，相邻两个第三冷凝管段33的螺旋线所在的圆柱面的直径的差值为固定值。由此，风道11内的气流可以在相邻两个第三冷凝管段33之间流动以与相邻两个第三冷凝管段33进行充分换热。
可以理解，每个第三冷凝管段33的螺旋线还可以大***于同一圆锥面上，每个第三冷凝管段33的螺旋线自上向下逐渐向内延伸，风管10的内径自上向下逐渐减小，风管10与处于最外面的第三冷凝管段33之间具有间隔。这样，风管10的形状能够为外界空气的进出提供导向，使外界空气能够更快速、顺畅地进出风道11，提高了换热效果。
可选地，每个第三冷凝管段33的进口和出口分别形成在最上端和最下端，相邻的两个第三冷凝管段33中，其中一个第三冷凝管段33的进口与另一个第三冷凝管段33的出口相对且连通。由此，制冷剂在每个第三冷凝管段33上自上向下流动(或自下向上流动)，且依次由内向外(或由外向内)在相邻两个第三冷凝管段33之间传递，提高了冷凝器100的换热效果。
在一些实施例中，制冷剂进口a和制冷剂出口b通过位于风管10底部的通过孔13伸出风管10外。制冷剂进口a与冰箱的压缩机出口相连通，制冷剂出口b与节流装置的进口相连通，由此实现了制冷***内高温高压气态制冷剂的冷凝。
需要说明的是，在上述实施例中，上下方向与风管10的轴向相一致，定义风道11(或风管10上)邻近送风装置20的一端为下端，远离送风装置20的一端为上端。送风装置20可以将气流从风管10的上端引入、下端引出，也可以将气流从风管10的下端引入、上端引出。
第一至第三冷凝管的管径、管壁厚度、管长以及管路的材质均影响冷凝器100的冷却效率和使用寿命，可以根据冰箱型号规格进行匹配设计。其中，第一至第三冷凝管的管路材质可采用金属管路(如铜管、铝管、铁管等)，具有良好的导热性和耐压性能，各个冷凝管的内外表面可以经电镀防蚀处理。
风管10可以采用经过表面防锈处理的金属(如镀锌钢板或不锈钢钢板)或者为耐热阻燃塑料成型件。如图11所示，风管10的底部具有用于与风扇连接的安装底脚12，安装底脚12上具有安装孔121，送风装置20与底脚12通过螺栓连接固定在一起。
如图12至图14所示，送风装置20可以采用微型的直流风扇，直流风扇可以使抽风式或吸风式，其功率及规格大小根据冰箱型号规格和冷凝管尺寸进行匹配。送风装置20通过安装支架40固定到制冷设备上。
根据本发明第二方面实施例的冰箱，包括上述实施例的冷凝器100。由此，采用上述冷 凝器100的冰箱具有更好的制冷效果。
制冷剂在冰箱的蒸发器中吸收冰箱箱体内部温度后，经压缩机压缩成为高温高压的蒸汽，被送往冷凝器100，冷凝器100向外界空气散热，将高温高压蒸气冷凝成液态制冷剂，然后经过节流装置节流，送入蒸发器，在蒸发器内制冷剂由于压力降低而剧烈沸腾蒸发，同时吸收箱体内被冷却物体的热量，产生制冷效果，制冷剂蒸汽再次送入压缩机，如此循环往复。
在一些实施例中，冰箱具有用于至少容纳压缩机的压缩机舱，送风装置20通过安装支架40固定到压缩机舱内。由此，合理利用了压缩机舱内的空间，当整机工作时，实现制冷剂与外界环境高效热交换，提高制冷效率。
