具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
如图1所示，本实施例的过冷器包括：气液分离器10和换热结构20。换热结构20与气液分离器10换热。
应用本实施例的技术方案，当冷媒中的气体夹带着液体通过气液分离器10时，气液分离器10将气体和液体分离，气液分离器10中的气态冷媒和液态冷媒通过换热结构20进行换热，进而提高了气液分离器10中的气体冷媒的过热度。本实施例的技术方案有效地解决了现有技术中的气液冷媒分离后气态冷媒过热度较低的问题。
如图1所示，在本实施例的技术方案中，气液分离器10包括气液进管11和出气管12，换热结构20包括第一容器21，第一容器21包括制冷冷媒入口22及液体冷媒出口23，气液分离器10位于第一容器21内，气液进管11和出气管12均穿出第一容器21。制冷冷媒从制冷冷媒入口22进入过冷器，当气液混合的冷媒通过气液分离器10进行气、液分离时，制冷冷媒对分离出的气体换热进而提高气体的过热度。本实施例的技术方案设计简单、使用方便。
如图1所示，在本实施例的技术方案中，第一容器21还包括制热冷媒入口24。上述结构通过制热冷媒对分离出的气体进行换热，提高气体的过热度。本实施例的过冷器结构简单，具有制冷冷媒或者制热冷媒对分离出的气体冷媒的换热的多功能的用途。
如图1所示，在本实施例的技术方案中，换热结构20还包括穿设在第一容器21上的第一进管，制冷冷媒入口22和制热冷媒入口24均设置在第一进管上。这样简化了结构，不用在第一容器21上同时设置制冷冷媒管道和制热冷媒管道。
如图1所示，在本实施例的技术方案中，第一进管位于第一容器21的顶壁上。具体地，第一进管居中设置在第一容器21的顶壁上。当制冷冷媒或者制热冷媒从第一进管流入第一容器21后，可以均匀地与气液分离器10接触换热，使得过冷器的换热效果较好。
如图1所示，在本实施例的技术方案中，液体冷媒出口23设置在第一容器21的底部。上述结构保证了液态冷媒能够全部流出，有利于节省能源。
如图1所示，在本实施例的技术方案中，气液分离器10包括：第二容器13，设置在第一容器21内，气液进管11和出气管12穿设在第一容器21上。上述结构在实现了换热的同时，还很好地将气液分离器10和换热结构20隔离。具体地，第一容器21由钢制成，气液分离器10的外壳和第二容器13均采用铝或者铝合金材质，由于铝和铝合金的传热效果更好，这样更提高了过冷器的换热能力。
本实施例的技术方案，一方面实现了使用冷凝放热后的液态冷媒来浇灌内部的气分，使得冷凝后的高温液态冷媒与内部的气分的低温两相冷媒进行换热，实现冷媒过冷，加大过冷度。另一方面，提高吸气过热度和油温过热度，减少液击的可能性，提高整机能效。还可以储存多余的液体冷媒，实现机组的长期可靠性运行。
如图1所示，在本实施例的技术方案中，出气管12为U型管。气液混合冷媒进入U型管的一端，经气液分离后气体从另一端逸出。具体地，U型管底部设置有过滤结构，以过滤气液冷媒的杂质，该过滤结构可以使冷媒中的压缩机油通过并带回压缩机。本实施例的过冷器还可以储存多余的液体冷媒，为机组提供冷媒，实现机组的长期可靠运行。第二容器13的底部设置有和第一容器21相连通的通孔以使液态冷媒从第二容器13流入第一容器21。当然，通孔的位置可以根据需要设置在第二容器13上。
如图1所示，在本实施例的技术方案中，第一容器21和第二容器13之间具有间隙。上述结构一方面保证了第二容器13不会受外界环境温度的影响，另一方面保证了第二容器13的换热效果。
如图2所示，本申请提供了一种空调器，根据本申请的空调器的实施例包括蒸发器30、冷凝器40及压缩机50，空调器还包括上述的过冷器，过冷器的气液分离器10位于蒸发器30及压缩机50之间的管路上，过冷器的换热结构20设置蒸发器30和冷凝器40之间的管路上。上述结构实现了空调器自身的液体冷媒与进入压缩机的气体冷媒实现了换热，进而提高进入压缩机的气体过热度。本实施例的技术方案，充分实现气液分离器10内的气液分离，提高吸气过热度，减少液击，同时在气液分离器10内冷却的润滑油随着气态冷媒进入压缩机，增加了压缩机50的润滑，进一步减少润滑油在蒸发器30和冷凝器40中残留，提高了换热效率，增加空调器运行的可靠性，提高整机能效。
如图3所示，在本实施例的技术方案中，过冷器为上述的过冷器，该过冷器的气液分离器10包括气液进管11和出气管12，换热结构20包括第一容器21，第一容器21包括制冷冷媒入口22及液体冷媒出口23，气液分离器10位于第一容器21内，气液进管11和出气管12穿出第一容器21。空调器还包括：四通阀60，四通阀60具有第一阀口61、第二阀口62、第三阀口63和第四阀口64，第一阀口61与压缩机50的入口相连，第二阀口62与压缩机50的出口相连，第三阀口63与蒸发器的第一端口31相连，第四阀口64与冷凝器的第一端口41相连，冷凝器的第二端口42与制冷冷媒入口22通过第一管路100相连，液体冷媒出口23与蒸发器的第二端口32通过第二管路200相连，气液分离器10的气液进管11与第一阀口61相连，气液分离器10的出气管12与压缩机50的入口相连。制冷时，气态冷媒从出气管12进入压缩机50，然后再通过四通阀60的第二阀口和第四阀口进入冷凝器40，通过冷凝器40 后再通过第一管路进入过冷器的制冷冷媒入口22，进入制冷冷媒入口22后从过冷器的液体冷媒出口23流入蒸发器30，冷媒流经蒸发器30后通过四通阀60的第三阀口和第一阀口进入过冷器的气液进管11，冷媒进行在气液分离器10进行气液分离后，气态冷媒进入压缩机50，经过上述过程后完成了制冷的循环(上述过程中，第三管路300和第四管路400上的阀门均处于关闭状态，因此未示出这两条管路)。上述结构将从压缩机50出来的冷媒对即将进入压缩机50的气态冷媒换热，提高了气态冷媒的过热度，上述结构设置合理，提高了压缩机的可靠性，提高了压缩机的能效。
如图4所示，在本实施例的技术方案中，过冷器为上述的过冷器，该过冷器的气液分离器10包括气液进管11和出气管12，换热结构20包括第一容器21，第一容器21包括制冷冷媒入口22、制热冷媒入口24及液体冷媒出口23，气液分离器10位于第一容器21内，气液进管11和出气管12穿出第一容器21。制热冷媒入口24与蒸发器的第二端口32通过第三管路300相连，当然，作为本领域技术人员知道，第三管路300的一端设置在蒸发器的第二端口32和第二管路200上的阀门之间的任意处即可，这样节省了第三管路300的长度。液体冷媒出口23与冷凝器的第二端口42通过第四管路400相连，当然，作为本领域技术人员知道，第四管路400的一端设置在冷凝器的第二端口42和第一管路100上的阀门之间的任意处即可，这样节省了第四管路400的长度。第一管路100、第二管路200、第三管路300和第四管路400均设置有阀门。制热时，气态冷媒从出气管12进入压缩机50，然后再通过四通阀60的第二阀口和第三阀口进入蒸发器30，从蒸发器30出来的冷媒进入过冷器的制热冷媒入口24而后再通过液体冷媒出口23进入冷凝器40，然后再通过四通阀60的第四阀口64和第一阀口61进入气液分离器10的气液进管11进行气液分离，最后经过换热后的气态冷媒从出气管12进入压缩机完成整个循环(上述过程中，第一管路100和第二管路200上的阀门均处于关闭状态，因此未示出这两条管路)。上述结构将从压缩机50出来的冷媒对即将进入压缩机50的气态冷媒换热，上述结构设置合理、节能效果较好。
如图1所示，在本实施例的技术方案中，阀门为单向阀，第一管路100的流向为冷凝器40至过冷器，第二管路200的流向为过冷器至蒸发器30，第三管路300的流向为蒸发器30至过冷器，第四管路400的流向为过冷器至冷凝器40。单向阀的设置方向均按上述的流向设置。上述结构减少了电磁阀等需要电路的元器件的阀门控制，进而本实施例的空调器使用周期长，故障率低。本实施例的技术方案还可以减小冷凝器40的大小，实现冷媒过冷，加大过冷度和单位质量流量冷媒的吸热量。
如图2所示，在本实施例的技术方案中，第三管路300和第四管路400汇合后通过总管与液体冷媒出口23相连，总管上设置有过滤器和膨胀阀。膨胀阀的设置有利于实现冷媒的换热。过滤器将冷媒中的颗粒物分离，保证了冷媒的洁净，有利于延长空调器的使用寿命。
优选地，气液进管11位于第二容器13内的管口与出气管12位于第二容器13内的管口沿水平方向错开，错开距离优选地大于50mm。出气管12位于第二容器13内的管口被设置在气液进管11位于第二容器13内的管口的上方，两者的高度差优选地大于50mm。如此设计目的在于，可使气液进管11引入的冷媒蒸汽经过充分加热，液态转变为气态，然后再引入至出气 管内，避免液击情况产生。出气管12位于所述第二容器13内的管口相对于水平面成20～40°，优选为30°的斜切口。
优选地，出气管12为U形管结构，在U形管结构的底部设有一个或多个回液孔或回液管，使得进入U形管结构的未完全蒸发的液体能够经由回液孔或回液管进入第二容器13的底部，以达到储存更多冷媒液体的目的，在机组缺少冷媒时，可以及时补充。回液孔的孔径或回液管的内径大小为3～4mm，回液孔或回液管的数量可根据实际需要来确定。
气液进管11和出气管12均可采用诸如铜管等材料制作，其与第一容器21和/或第二容器13可采用焊接等方式固定连接。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
