如图1-图3所示，根据本发明实施例的冰箱1包括箱体(图中未示出)、第一内胆110、第二内胆120、丝管蒸发器和绕管蒸发器300。
第一内胆110和第二内胆120均设置在所述箱体内。所述丝管蒸发器包括设在第一内胆110内的第一丝管蒸发器210和设在所述第二内胆内的第二丝管蒸发器，绕管蒸发器300包括绕设在第一内胆110外的第一绕管蒸发器310和绕设在第二内胆120外的第二绕管蒸发器320，第一丝管蒸发器210的两端均具有第一连接管，两个所述第一连接管均伸出第一内胆110，第一绕管蒸发器310与两个所述第一连接管中的一个的自由端相连，所述第二丝管蒸发器的两端均具有第二连接管，两个所述第二连接管均伸出第二内胆120，第二绕管蒸发器320与两个所述第二连接管中的一个的自由端相连，两个所述第一连接管中的另一个的自由端与两个所述第二连接管中的另一个的自由端相连。
根据本发明实施例的冰箱1，通过设置第一丝管蒸发器210和第一绕管蒸发器310，可以利用第一丝管蒸发器210和第一绕管蒸发器310共同对第一内胆110进行制冷，通过设置所述第二丝管蒸发器和所述第二绕管蒸发器，可以利用所述第二丝管蒸发器和所述第二绕管蒸发器共同对第二内胆120进行制冷。由此不仅可以提高对第一内胆110和第二内胆120的制冷效果，而且可以将第一丝管蒸发器210设置在第一内胆110内温度较高的区域，将所述第二丝管蒸发器设置在第二内胆120内温度较高的区域，以使第一内胆110和第二内胆120内的温度更加均匀，减小冰箱1内的温差，提高冰箱1的能效。例如，由于冷空气下沉，可以将第一丝管蒸发器210设置在第一内胆110的上部，将所述第二丝管蒸发器设置在第二内胆120的上部，从而使冰箱1的制冷效果更加均匀。
此外，通过设置所述第一连接管和所述第二连接管，且所述第一连接管伸出第一内胆110，所述第二连接管伸出第二内胆120，这样在连接第一丝管蒸发器210时可以在第一内胆110外进行操作，在连接所述第二丝管蒸发器时可以在第二内胆120外进行操作，不仅可以扩大安装人员的操作空间，便于操作人员对第一丝管蒸发器210和所述第二丝管蒸发器进行连接，提高第一丝管蒸发器210和所述第二丝管蒸发器的装配效率，以提高冰箱1的生产效率，而且可以防止在第一内胆110和第二内胆120内进行操作时损坏第一内胆110和第二内胆120，降低第一内胆110和第二内胆120的废品率。例如，第一丝管蒸发器210 可以与第一绕管蒸发器310通过焊接连接，所述第二丝管蒸发器可以与第二绕管蒸发器320通过焊接连接，第一丝管蒸发器210可以与所述第二丝管蒸发器焊接连接，这样可以在第一内胆110和第二内胆120外进行焊接，以扩大操作空间，防止第一内胆110和第二内胆120被熏黑。
并且，由于第一绕管蒸发器310与两个所述第一连接管中的一个的自由端相连，第二绕管蒸发器320与两个所述第二连接管中的一个的自由端相连，两个所述第一连接管中的另一个的自由端与两个所述第二连接管中的另一个的自由端相连。这样可以使冷凝剂先经过一个绕管蒸发器，再经过两个丝管蒸发器，最后经过一个绕管蒸发器，换言之，冷凝剂可以依次经过第一绕管蒸发器310、第一丝管蒸发器210、所述第二丝管蒸发器和第二绕管蒸发器320，也可以依次经过第二绕管蒸发器320、所述第二丝管蒸发器、第一丝管蒸发器210和第一绕管蒸发器310。由于冷凝剂在流路中流动的过程中，随流程的增加而吸热升温，这样设置不仅可以降低第一内胆110和第二内胆120之间的温差，也可以降低第一内胆110内的温差以及第二内胆120内的温差，从而进一步使冰箱1的制冷效果更加均匀。
因此，根据本发明实施例的冰箱1具有制冷均匀、装配方便、废品率低等优点。
下面参考附图描述根据本发明具体实施例的冰箱1。
第一内胆110和第二内胆120可以沿左右方向并排设置，两个所述第一连接管可以包括第一左连接管211和第一右连接管212，第一左连接管211与第一右连接管212沿左右方向间隔设置，两个所述第二连接管可以包括第二左连接管213和第二右连接管214，第二左连接管213与第二右连接管214沿左右方向间隔设置。由此可以便于第一左连接管211、第一右连接管212、第二左连接管213和第二右连接管214的形成。
有利地，如图1所示，第一绕管蒸发器310可以与第一左连接管211相连，第二绕管蒸发器320可以与第二右连接管214相连，第一右连接管212可以与第二左连接管213相连。由此可以便于第一绕管蒸发器310与第一左连接管211相连，便于第二绕管蒸发器320与第二右连接管214相连，便于第一右连接管212与第二左连接管213相连，而且可以便于控制管路长度，一方面可以降低材料成本，另一方面可以降低冷凝剂的冷量损失，从而提高冰箱1的制冷效率。
更为有利地，如图1所示，第一右连接管212可以与第二左连接管213的高度相同，第一右连接管212的自由端可以向右折弯且折弯处圆弧过渡，第二左连接管213的自由端可以向左折弯且折弯处圆弧过渡。由此可以进一步便于第一右连接管212与第二左连接管213相连，而且可以减小冷凝剂流过第一右连接管212和第二左连接管213时的阻力。
图1-图3示出了根据本发明一个具体示例的冰箱1。如图1-图3所示，第一内胆110上可以设有两个第一管路过孔，第二内胆120上可以设有两个第二管路过孔，两个所述第 一连接管分别通过两个所述第一管路过孔伸出第一内胆110，两个所述第二连接管分别通过两个所述第二管路过孔伸出第二内胆120。由此不仅可以便于两个所述第一连接管伸出第一内胆110，便于两个所述第二连接管伸出第二内胆120，而且可以防止所述第一连接管占用第一内胆110前方的空间，防止所述第二连接管占用第二内胆120前方的空间，从而提高空间的利用率。此外，还可以防止所述第一连接管和所述第二连接管的结构外露而影响美观。
有利地，如图2和图3所示，所述第一管路过孔内可以配合有第一柔性套管111，所述第一连接管可以配合在第一柔性套管111内，所述第二管路过孔内可以配合有第二柔性套管，所述第二连接管可以配合在所述第二柔性套管内。具体而言，第一柔性套管111和所述第二柔性套管可以均为橡胶套管。由此可以利用第一柔性套管111和所述第二柔性套管对所述第一连接管和所述第二连接管进行缓冲，不仅可以防止所述第一连接管和所述第二连接管因碰撞而损坏，而且可以防止所述第一连接管和所述第二连接管因碰撞发出噪音。
具体地，如图2和图3所示，第一内胆110的内侧壁面上可以设有第一支撑凸台112，第一丝管蒸发器210支撑在第一支撑凸台112上，第二内胆120的内侧壁面上可以设有第二支撑凸台，所述第二丝管蒸发器支撑在所述第二支撑凸台上。由此可以利用第一支撑凸台112和所述第二支撑凸台分别支撑第一丝管蒸发器210和所述第二丝管蒸发器，从而便于对第一丝管蒸发器210和所述第二丝管蒸发器进行安装。
更为具体地，如图2和图3所示，第一内胆110内可以设有第一固定卡113，第一丝管蒸发器210可以安装在第一固定卡113上，第二内胆120内可以设有第二固定卡，所述第二丝管蒸发器可以安装在所述第二固定卡上。由此可以利用第一固定卡113和所述第二固定卡分别固定第一丝管蒸发器210和所述第二丝管蒸发器，从而便于将第一丝管蒸发器210和所述第二丝管蒸发器分别设置在第一内胆110和第二内胆120内。
其中，如图2和图3所示，第一固定卡113可以设在第一内胆110的内顶壁上，所述第一丝管蒸发器可以设在第一固定卡113上且邻近第一内胆110的顶壁，所述第二固定卡可以设在第二内胆120的内顶壁上，所述第二丝管蒸发器可以设在所述第二固定卡上且邻近第二内胆120的顶壁。由此可以便于将第一丝管蒸发器210和所述第二丝管蒸发器分别设置在第一内胆110和第二内胆120的上部，以便于均衡冰箱1的制冷效果。
可选地，如图1所示，第一绕管蒸发器310可以在从后至前的方向上沿顺时针绕设在第一内胆110外，第二绕管蒸发器320可以在从后至前的方向上沿顺指针绕设在第二内胆120外。由此不仅可以便于第一绕管蒸发器310与第一丝管蒸发器210相连，便于第二绕管蒸发器320与所述第二丝管蒸发器相连，而且可以进一步提高冰箱1制冷效果的均匀性。
当然，第二绕管蒸发器320和第一绕管蒸发器310也可以根据实际需要按其他方式绕 设。
