下面参考图1-图7描述根据本发明实施例的制冷设备用冷凝器30。
如图1-图7所示，根据本发明的制冷设备用冷凝器30，包括：壳体31和冷凝器本体32，壳体31内限定有容纳腔301，冷凝器本体32设置在容纳腔301内，且冷凝器本体32的两端伸出容纳腔301外，从而可以适于与制冷设备的压缩机10和蒸发器20连接，其中，容纳腔301内储存有冷却液，用于对冷凝器本体32进行散热。
根据本发明实施例的制冷设备用冷凝器30，通过设置带有壳体31的冷凝器30，通过在壳体31内储存冷却液，使得散热过程中冷凝器本体32首先与冷却液接触，将冷凝器本体32内的热量快速地传递到冷却液内，再将冷却液内储存的热量均匀散发到外界，实现快速转移冷凝器本体32的热量，同时实现均衡散热，降低能耗。
根据本发明的一个实施例，壳体31包括：环形外壳311、环形内壳312、前盖板313和后盖板314，环形内壳312设置在环形外壳311内，且环形内壳312与环形外壳311间隔布置，前盖板313密封连接在环形外壳311与环形内壳312的前侧，后盖板314密封连接在环形外壳311与环形内壳312的后侧，后盖板314、前盖板313、环形外壳311和环形内壳312之间限定出容纳腔301。
其中，前盖板313和后盖板314中的一个具有第一通孔315，从而可以适于冷凝器本体32的一端伸出，前盖板313和后盖板314中的另一个具有第二通孔，从而可以适于冷凝器本体32的另一端伸出，环形外壳311的背向容纳腔301的一侧表面和环形内壳312背向容纳腔301的一侧表面中的至少一个上设有多个散热片，多个散热片间隔设置。
在一些示例中，冷凝器本体32形成环形，容纳腔301形成环形腔，容纳腔301形成一个密封的空间，冷却液为比热容较大的液体，密封的容纳腔301可以便于冷却液的储存，防止冷却液泄露流出，影响制冷系统100的工作性能。
进一步地，前盖板313上具有第一通孔315，后盖板314中上具有第二通孔316，冷 凝器本体32的一端从第一通孔315伸出，从而与制冷系统100的蒸发器20连接，冷凝器本体32的另一端从第二通孔316伸出，从而与制冷系统100的压缩机10连接。环形内壳312内侧表面设有多个第一散热片317，环形外壳311的外侧表面设有多个第二散热片，多个第一散热片317和第二散热片分别间隔设置，增加了壳体31的换热面积，更加有利于容纳腔301内冷却液热量的散发。
根据本发明的一个实施例，冷却液为比热容较大的液体，例如纯水。当制冷系统100启动制冷时，冷凝器30进行放热，通过冷凝器本体32与壳体31内的冷却液进行热量交换，快速将热量从冷凝器本体32传递到冷却液内，由于冷凝器本体32内的冷媒是气态，比热容小，相比而下，冷却液比热容很大，从而冷却液的温度上升较慢。在制冷系统100的使用过程中，冷却液的温度会稳定在一个小范围，进一步提升制冷系统100的稳定性。
根据本发明的一个可选实施例，容纳腔301形成环形腔，冷凝器本体32形成沿环形腔的一圈环形，或沿周向顺时针或逆时针延伸的多圈环形，由此增大冷凝器本体32的外表面积，即增大冷凝器本体32的换热面积。冷凝器本体32放置在环形腔内，冷却液储存在环形腔内，通过环形腔的内侧和外侧同步散热，提高了散热速度，从而进一步减小能耗。
根据本发明的另一个可选实施例，容纳腔301形成环形腔，冷凝器本体32沿环形腔的周向往复延伸，冷凝器本体32包括相互连通的多段冷凝管，相邻两段冷凝管内的冷媒流动方向相反，同样可以增大冷凝器本体32的换热面积。
在一些示例中，冷凝器本体32包括：多个沿容纳腔301的轴向(如图3所示的前后方向)间隔排布的冷凝管、输入管和输出管。每个冷凝管形成具有缺口的环形(例如，形成图3中所示的具有缺口的“口”字形)，且多个冷凝管的缺口位于同一侧。
其中，位于中间位置的冷凝管的一端和与其相邻的上一个冷凝管的一端过渡连接，位于中间位置的冷凝管的另一端和与其相邻的下一个冷凝管的一端过渡连接，由此实现多个冷凝管的往复延伸。输入管和输出管分别与位于最外端的两个冷凝管的一端连接，即输入管和输出管分别与最前侧和最后侧的冷凝管的一端连接，从而使冷凝器本体32形成一体的结构，便于冷媒的传递。
如图2-图4所示，在一些具体示例中，壳体31的横截面形状可以形成“回”字形，即环形腔形成“口”字形。
根据本发明的一个实施例，壳体31包括：环形外壳311、环形内壳312、前盖板313和后盖板314，环形内壳312设置在环形外壳311内，且环形内壳312与环形外壳311 间隔布置，前盖板313密封连接在环形外壳311与环形内壳312的前侧，后盖板314密封连接在环形外壳311与环形内壳312的后侧，后盖板314、前盖板313、环形外壳311和环形内壳312之间限定出容纳腔301，从而使容纳腔301形成一个密封的空间，便于冷却液的储存，防止冷却液泄露流出，影响制冷系统100的工作性能。
在一些示例中，环形外壳311、环形内壳312和后盖板314可以一体成型，前盖板313与其可拆卸地连接，从而便于将冷凝器本体32放入容纳腔301内，将冷凝器本体32放入容纳腔301后，在容纳腔301内灌入冷却液，再将前盖板313与壳体31的其他部分密封连接，从而组装成冷凝器30。
如图3所示，在一些示例中，前盖板313和后盖板314中的一个具有第一通孔315，前盖板313和后盖板314中的另一个具有第二通孔316，从而使冷凝器本体32的一端可以从第一通孔315伸出，冷凝器本体32的另一端可以从第二通孔316伸出，进而使冷凝器本体32的一端与制冷系统100的压缩机10连接，使冷凝器本体32的另一端与制冷系统100的蒸发器20连接，连接方便。
在一些示例中，冷凝器本体32的两端分别与前盖板313和后盖板314密封连接，即冷凝器本体32的两端外周壁与对应位置的通孔内壁密封连接。
在一些具体示例中，冷凝器30还包括两个密封环(图中未示出)，两个密封环分别固定在第一通孔315和第二通孔316处，冷凝器本体32的两端分别穿过两个密封环，从而实现冷凝器本体32与壳体31的密封连接，以便于壳体31内形成密封的容纳腔301，防止冷却液泄露流出。
当然，冷凝器本体32与前盖板313和后盖板314上第一通孔315和第二通孔316的密封方式并不仅限于上述描述的方式，冷凝器本体32还可以通过密封防水胶等方式与前盖板313和后盖板314上的第一通孔315和第二通孔316密封连接。
如图4-图7所示，在一些示例中，环形内壳312的背向容纳腔301的一侧(即环形内壳312的内侧)表面设有多个第一散热片317，多个第一散热片317间隔设置，从而可以增加环形内壳312的换热面积。
在一些具体的示例中，第一散热片317沿其所在的环形内壳312的表面的法线延伸，即第一散热片317的延伸方向与环形内壳312的内表面方向垂直，有利于容纳腔301内冷却液热量的散发。
在另一些示例中，环形外壳311的背向容纳腔301的一侧(即环形外壳311的外侧)表面设有多个第二散热片(图中未示出)，多个第二散热片间隔设置，从而可以增加环形外壳311的换热面积。
在一些具体的示例中，第二散热片沿其所在的环形外壳311的表面的法线延伸，即第二散热片的延伸方向与环形外壳311的外表面方向垂直，同时有利于容纳腔301内冷却液热量的散发。
在又一些示例中，环形内壳312的背向容纳腔301的一侧表面设有多个第一散热片317，环形外壳311的背向容纳腔301的一侧表面设有多个第二散热片，多个第一散热片317和第二散热片分别间隔设置，从而可以增加壳体31的换热面积，更加有利于容纳腔301内冷却液热量的散发。
当然，第一散热片317和第二散热片的安装方式并不限于上述限定，即第一散热片317与第二散热片可以不与所在的壳体31表面垂直，而第一散热片317和第二散热片的形状可以形成矩形、扇形、三角形、其他形状中的一种或多种组合。
根据本发明的一个实施例，壳体31由导热材料制成，壳体31内的冷却液可以持续与周围空气换热，以实现24小时不停换热，在保证散热的同时也能有效节约能源，降低制冷系统100的能耗。
如图1-图7所示，根据本发明一个实施例的制冷系统100包括：压缩机10、蒸发器20和根据本发明实施例的制冷设备用冷凝器30。蒸发器20与压缩机10连接，冷凝器30分别与蒸发器20和压缩机10连接。
根据本发明实施例的制冷系统100，通过设置带有壳体31的冷凝器30，通过在壳体31内储存冷却液，使得散热过程中冷凝器本体32首先与冷却液接触，将热量通过冷凝器本体32快速地传递到冷却液内，再将冷却液内储存的热量均匀散发到外界，实现快速转移冷凝器本体32的热量，从而达到长时间均衡散热，即可以实现24小时不间断散热，降低了制冷系统100的温度波动量，同时可以降低制冷系统100对风扇40的风量要求，进而减小噪音，降低能耗。
根据本发明的一个实施例，制冷系统100还包括可转动的风扇40，风扇40布置在邻近冷凝器30处，从而可以对冷凝器30以及压缩机10吹风，实现降温效果。
具体地，在制冷系统100散热过程中，冷凝器本体32首先与冷却液接触，将冷凝器本体32的热量快速地传递到冷却液内，风扇40转动同时对冷却液和冷凝器本体32降温，使得冷却液内储存的热量均匀散发到外界，实现均匀散热，其中，由于冷凝器30的容纳腔301内的冷却液可以相当于一个蓄冷装置，从而不需要快速散热，可以使用较小的风扇40进行散热，有效地降低了制冷系统100的噪音。
在一些示例中，当制冷系统100停止运行，风扇40停转，由于壳体31采用导热材料制成，使得冷却液可以持续与周围空气换热，实现24小时不停换热，从而可以有效 地节约能源，降低制冷系统100的能耗。
进一步地，风扇40的运转还可以与容纳腔301内冷却液的温度建立关联，即通过容纳腔301内的温度控制风扇40运转。例如，当冷却液的温度高于预设温度时，再启动风扇40，进一步地降低制冷系统100的噪音和能耗。
根据本发明的制冷设备(图中未示出)，包括根据本发明实施例的制冷系统100，通过采用上述制冷系统100，通过冷凝器本体32首先与冷却液接触，将冷凝器本体32内的热量快速地传递到冷却液内，再将冷却液内储存的热量均匀散发到外界，实现快速转移冷凝器本体32的热量，同时长时间均衡散热，降低了制冷设备内部的温度波动量，同时可以降低制冷设备对风扇40的风量要求，进而减小噪音，降低能耗。
根据本发明实施例的制冷系统100、制冷设备以及制冷设备用冷凝器30的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
