下面参考附图描述根据本公开实施例的空调室外机1。
如图1-图5所示，根据本公开实施例的空调室外机1包括壳体100、压缩机200、储液器300和热管400。
压缩机200安装于壳体100内。储液器300安装于壳体100内且与压缩机200的回气口连通。热管400具有蒸发部410和冷凝部420，蒸发部410与压缩机200接触导热，冷凝部420与储液器300接触导热。
具体而言，压缩机200运行过程中产生的热量通过压缩机200的壳体被热管400 吸收，热管400内部的介质吸收热量后汽化形成蒸发部410，蒸汽在微小的压力差下流向热管400的另一端，与较冷的储液器300进行热交换后释放热量液化，热管400内部的介质重新凝结成液体形成冷凝部420，液化后液体再经多孔材料(如吸液芯)靠毛细力的作用流回到蒸发部410。如此循环不止，热量由热管400的蒸发部410传导至冷凝部420，压缩机200运行产生的热量源源不断地传导至储液器300，达到降温的目的，有效保护压缩机200，保证压缩机200持续运行，避免压缩机200温度过高而烧毁。根据本公开实施例的空调室外机1，通过设置热管400，且热管400的蒸发部410与压缩机200接触导热，热管400的冷凝部420与储液器300接触导热，这样可以利用热管400将压缩机200运行时产生的热量持续传导至储液器300，有效降低压缩机200的温度，从而避免压缩机200反复停机，提高了压缩机200的使用寿命，且在制冷和制热过程中，压缩机200无需停机保护，能够保证环境的舒适性。
并且，压缩机200的热量传导至储液器300，能够促使储液器300内的制冷剂向气态转化，从而提升压缩机200的回气温度，进而避免液击现象，并提升整机能效，且在低温制热下，能够有效提升制热能力。
因此，根据本公开实施例的空调室外机1，能够对压缩机进行过热保护，且具有使用寿命长、舒适性高、防止液击、能效高等优点。
在本公开的一些具体实施例中，如图1所示，空调室外机1还包括导热安装板500。
导热安装板500贴设于压缩机200和储液器300，热管400安装于导热安装板500，导热安装板500将蒸发部410压紧于压缩机200且将冷凝部420压紧于储液器300。导热安装板500能够为热管400提供安装载体，并将热管400稳定固定于压缩机200和储液器300，保证热量的有效传导。而且，导热安装板500具有导热功能，例如导热安装板500可以为铝板，具有优良的导热性和结构强度，如此，增加了换热面积，从而提高热传导效率。
在本公开的一些具体实施例中，如图5所示，导热安装板500的朝向压缩机200的表面构造有第一管槽510，蒸发部410的至少一部分装配于第一管槽510。导热安装板500的朝向储液器300的表面构造有第二管槽520，冷凝部420的至少一部分装配于第二管槽520。
例如，第一管槽510和第二管槽520的横截面可以均呈圆弧形，第一管槽510适应于蒸发部410的外轮廓，第二管槽520适应于冷凝部420的外轮廓，热管400采用滚压工艺，分别压装到导热安装板500的第一管槽510与第二管槽520内。由此，热管400与导热安装板500的位置更加稳定，第一管槽510与蒸发部410具有较大的接触面积，热量传递效率更高。同样地，第二管槽520与冷凝部420具有较大的接触面积， 冷凝部420邻近储液器300一侧，使冷凝部420的热量能够更快传递至储液器300，进而加快压缩机200与储液器300之间热传导的速度。
在本公开的一些具体实施例中，如图3和图4，空调室外机1还包括至少一个固定箍600。
固定箍600与导热安装板500相连，固定箍600与导热安装板500之间限定出压缩机固定空间610和储液器300固定空间，压缩机200被抱持于压缩机固定空间610，储液器300被抱持于储液器300固定空间。压缩机固定空间610与压缩机200的外轮廓相适应，储液器300固定空间与储液器300的外轮廓相适应，固定箍600和导热安装板500共同起到固定压缩机200和储液器300的作用，从而将热管400固定于压缩机200和储液器300。
在本公开的一些具体实施例中，如图2所示，导热安装板500包括压缩机导热部530、储液器导热部540和连接在压缩机导热部530和储液器导热部540之间的中间导热部550。
如图3和图4所示，固定箍600包括压缩机固定部630、储液器固定部640和连接在压缩机固定部630和储液器固定部640之间的连接部650。
其中，压缩机固定部630与压缩机导热部530之间、储液器固定部640与储液器导热部540之间以及连接部650与中间导热部550之间分别通过螺纹紧固件连接，如图5所示，压缩机固定部630和压缩机导热部530共同限定出压缩机固定空间610，储液器固定部640和储液器导热部540共同限定出储液器固定空间620。
通过设置压缩机导热部530，使压缩机200的热量可以快速传递至蒸发部410。通过设置储液器导热部540，使冷凝部420的热量可以快速传递至储液器300。中间导热部550将压缩机导热部530和储液器导热部540相连接，提高了导热安装板500的结构强度，且增加了热传导的途径。导热安装板500的横截面形成开口方向相同且相连的两个半圆环形状，适应于压缩机200和储液器300的安装。固定箍600与导热安装板500通过螺纹紧固件连接，使压缩机200和储液器300能够始终处于压缩机固定空间610和储液器固定空间620内，压缩机200和储液器300的装配更加牢固。压缩机200与储液器300相邻设置且延伸方向相同。导热安装板500和固定箍600共同将压缩机200和储液器300固定在距离较近的位置，换热效率更高。
在本公开的一些具体实施例中，如图3所示，蒸发部410的朝向压缩机200的表面构造有第一凹面411，第一凹面411与压缩机200的外周面贴合。冷凝部420的朝向储液器300的表面构造有第二凹面412，第二凹面412与储液器300的外周面贴合。
例如，热管400通过飞面加工形成第一凹面411和第二凹面412，第一凹面411与 压缩机200的外周面具有更大的换热面积，利于蒸发部410吸收压缩机200产生的热量。第二凹面412与储液器300的外周面具有更大的换热面积，利于冷凝部420将热量传递至储液器300，进而提高了压缩机200向储液器300传递热量的效率。
在本公开的一些具体实施例中，如图2所示，蒸发部410沿压缩机200的轴向延伸，冷凝部420沿储液器300的轴向延伸。
由此，压缩机200轴向的各处的热量均能够传递至蒸发部410，进而蒸发部410对压缩机200冷却更均匀。冷凝部420能够充分将热量传递至储液器300，使储液器300内的制冷剂均匀吸收热量，进而压缩机200的回气温度得到提升。
在本公开的一些具体实施例中，如图2所示，热管400还包括中间部430，中间部430连接在蒸发部410和冷凝部420之间，例如，中间部430连接在蒸发部410和冷凝部420的下方，中间部430的高度沿冷凝部420至蒸发部410的方向逐渐降低。
由于中间部430的高度沿冷凝部420至蒸发部410的方向逐渐降低，热管400的热量传输路径较为平缓，介质在中间部430传递阻力较小，且冷凝部420中冷却后的介质在重力作用下斜度回流至蒸发部410。
在本公开的一些具体实施例中，蒸发部410与压缩机200之间以及冷凝部420与储液器300之间分别设有导热胶。导热胶质地较软，能够填充蒸发部410与压缩机200之间的间隙以及冷凝部420与储液器300之间的间隙，提升蒸发部410与压缩机200之间以及冷凝部420与储液器300之间的导热效果。
在本公开的一些具体实施例中，如图2所示，热管400为多个，多个热管400的蒸发部410沿压缩机200的周向间隔设置，多个热管400的冷凝部420沿储液器300的周向间隔设置，多个热管400可以均由导热安装板500固定。
通过设置多个热管400，使压缩机200与多个蒸发部410接触导热，储液器300与多个冷凝部420接触导热，进一步加强了蒸发部410对压缩机200的冷却效果，并加强了冷凝部420对储液器300中的回气温度的提升效果，促进压缩机200和储液器300之间的热量传递。
下面参考附图描述根据本公开另一个实施例的空调室外机1。
如图6-图9所示，根据本公开实施例的空调室外机1包括壳体100、压缩机200、储液器300、热管400和加热棒1000。
压缩机200安装于壳体100内。储液器300安装于壳体100内且与压缩机200的回气口连通。热管400具有蒸发部410和冷凝部420，蒸发部410与压缩机200接触导热，冷凝部420与储液器300接触导热。加热棒1000与储液器300接触导热。
举例而言，压缩机200运行过程中产生的热量通过压缩机200的壳体100被热管 400吸收，热管400内部的介质吸收热量后汽化形成蒸发部410，蒸汽在微小的压力差下，流向热管400的另一端，与较冷的储液器300进行热交换后释放热量液化，热管400内部的介质重新凝结成液体形成冷凝部420，液化后液体在加热棒1000与储液器300接触导热，再经多孔材料(如吸液芯)靠毛细力的作用流回到蒸发部410。如此循环不止，热量由热管400的蒸发部410传导至冷凝部420，压缩机200运行产生的热量源源不断地传导至储液器300，并结合加热棒1000的加热作用，提高了压缩机200的回气温度，提升除霜时的蒸发压力，实现不间断制热，压缩机200无需停机。
具体地，如图9所示，空调室外机1所对应的制冷系统包括压缩机200、四通换向阀901、室内换热器700、电子膨胀阀902、室外换热器800和储液器300，上述部件依次连接成制冷剂回路。
除霜运行时，电子膨胀阀902全开，压缩机200降频，室内风扇、室外风扇110减速转动，压缩机200排出的高温高压制冷剂通入室外换热器800起到除霜的效果，热管400吸收压缩机200的热量并传导至储液器300，同时加热棒1000工作，储液器300内部低温制冷剂吸收热管400和加热棒1000的热量，温度升高，提升了回气温度，提高除霜蒸发压力，减少系统运行功率，提高整机系统能效、提高舒适性。
其中，加热棒1000可以为电加热部件，由空调室外机1的控制单元控制，以在除霜运行时开启。
根据本公开实施例的空调室外机1，通过设置热管400和加热棒1000，且热管400的蒸发部410与压缩机200接触导热，热管400的冷凝部420与储液器300接触导热，这样可以利用热管400将压缩机200运行时产生的热量持续传导至储液器300，在结合加热棒1000的加热作用下，促使储液器300内的制冷剂向气态转化，从而提升压缩机200的回气温度，进入提高除霜蒸发压力，由此，空调室外机1在除霜运行时，压缩机200无需停机，实现不间断制热，从而提高舒适性。并且相比相关技术中的双蒸发器交替除霜、多个旁通电磁阀和蓄热器等方案，控制逻辑更加简单、成本更低。
因此，根据本公开实施例的空调室外机1能够实现不间断制热，不停机除霜，具有舒适性高、使用寿命长、控制简单、成本较低等优点。
在本公开的一些具体实施例中，如图7所示，空调室外机1还包括导热安装板500。导热安装板500贴设于压缩机200和储液器300，热管400和加热棒1000安装于导热安装板500，导热安装板500将蒸发部410压紧于压缩机200且将冷凝部420压紧于储液器300，加热棒1000埋设于导热安装板500。
导热安装板500能够为热管400和加热棒1000提供安装载体，并将热管400稳定固定于压缩机200和储液器300，加热棒1000构造成长圆柱且大部分固定于导热安装 板500内部，释放出的热量能够充分传递至导热安装板500和储液器300，保证热量的有效传导。而且导热安装板500具有导热功能，例如导热安装板500可以为铝板，具有优良的导热性和结构强度，如此，增加了换热面积，从而提高热传导效率，使热量的传递更加均匀。
进一步地，如图8所示，导热安装板500的朝向压缩机200的表面构造有第一管槽510，蒸发部410的至少一部分装配于第一管槽510。导热安装板500的朝向储液器300的表面构造有第二管槽520，冷凝部420的至少一部分装配于第二管槽520。
例如，第一管槽510和第二管槽520的横截面可以均呈优弧形，第一管槽510适应于蒸发部410的外轮廓，第二管槽520适应于冷凝部420的外轮廓，热管400采用滚压工艺，分别压装到导热安装板500的第一管槽510与第二管槽520内。由此，热管400与导热安装板500的位置更加稳定，第一管槽510与蒸发部410具有较大的接触面积，热量传递效率更高。同样地，第二管槽520与冷凝部420具有较大的接触面积，冷凝部420邻近储液器300一侧，使冷凝部420的热量能够更快传递至储液器300，进而加快压缩机200与储液器300之间热传导的速度。
在本公开的一些具体实施例中，如图7和图8所示，导热安装板500包括第一导热安装板601和第二导热安装板602。
第一导热安装板601和第二导热安装板602相连且限定出压缩机固定空间610和储液器固定空间620，压缩机200被抱持于压缩机固定空间610，储液器300被抱持于储液器固定空间620，第一导热安装板601和第二导热安装板602中的每一个均设有热管400和加热棒1000。
具体地，第一导热安装板601的与压缩机200接触的表面以及第二导热安装板602的与储液器300接触的表面构造成圆弧面，以适应于压缩机200和储液器300的安装，压缩机200和储液器300能够始终处于压缩机固定空间610和储液器固定空间620内，压缩机200和储液器300的装配更加牢固。并且第一导热安装板601和第二导热安装板602与压缩机200和储液器300抱持，导热安装板500与压缩机200和储液器300的外周面具有更大的导热面积，使压缩机200和储液器300的热量传导更充分。
进一步地，如图7和图8所示，第一导热安装板601和第二导热安装板602中的每一个包括压缩机导热部530、储液器导热部540和连接在压缩机导热部530和储液器导热部540之间的中间导热部550。
通过设置压缩机导热部530，使压缩机200的热量可以快速传递至蒸发部410。通过设置储液器导热部540，使冷凝部420的热量可以快速传递至储液器300。中间导热部550将压缩机导热部530和储液器导热部540相连接，提高了导热安装板500的结 构强度，且增加了热传导的途径。
其中，第一导热安装板601的压缩机导热部530与第二导热安装板602的压缩机导热部530之间、第一导热安装板601的储液器导热部540与第二导热安装板602的储液器导热部540之间以及第一导热安装板601的中间导热部550与第二导热安装板602的中间导热部550之间分别通过螺纹紧固件(例如螺栓)连接。
第一导热安装板601的压缩机导热部530和第二导热安装板602的压缩机导热部530共同限定出压缩机固定空间610，第一导热安装板601的储液器导热部540和第二导热安装板602的储液器导热部540共同限定出储液器固定空间620。
由此，第一导热安装板601和第二导热安装板602在压缩机导热部530、储液器导热部540和中间导热部550之间均通过螺纹紧固件连接，通过导热安装板500将压缩机200和储液器300固定，具有更稳定的装配结构。
在本公开的一些具体实施例中，如图7所示，蒸发部410的朝向压缩机200的表面构造有第一凹面411，第一凹面411与压缩机200的外周面贴合。冷凝部420的朝向储液器300的表面构造有第二凹面421，第二凹面421与储液器300的外周面贴合。
例如，热管400通过飞面加工形成第一凹面411和第二凹面421，第一凹面411与压缩机200的外周面具有更大的换热面积，利于蒸发部410吸收压缩机200产生的热量。第二凹面421与储液器300的外周面具有更大的换热面积，利于冷凝部420将热量传递至储液器300，进而提高了压缩机200向储液器300传递热量的效率。
在本公开的一些具体实施例中，如图7所示，蒸发部410沿压缩机200的轴向延伸。冷凝部420和加热棒1000沿储液器300的轴向延伸。
由此，压缩机200轴向的各处的热量均能够传递至蒸发部410，进而蒸发部410对压缩机200冷却更均匀。冷凝部420能够充分将热量传递至储液器300，使储液器300内的制冷剂均匀吸收热量。同时加热棒1000发热能够传递至储液器300轴向的各处，储液器300内的制冷剂得到了加热，进而压缩机200的回气温度得到提升。
在本公开的一些具体实施例中，如图7所示，热管400还包括中间部430。
中间部430连接在蒸发部410和冷凝部420之间，中间部430的高度沿冷凝部420至蒸发部410的方向逐渐降低。
由于中间部430的高度沿冷凝部420至蒸发部410的方向逐渐降低，热管400的热量传输路径较为平缓，介质在中间部430传递阻力较小，且冷凝部420中冷却后的介质在重力作用下斜度回流至蒸发部410。
在本公开的一些具体实施例中，蒸发部410与压缩机200之间以及冷凝部420与储液器300之间分别设有导热胶。
导热胶质地较软，能够填充蒸发部410与压缩机200之间的间隙以及冷凝部420与储液器300之间的间隙，提升蒸发部410与压缩机200之间以及冷凝部420与储液器300之间的导热效果。
在本公开的一些具体实施例中，如图7所示，热管400为多个，多个热管400的蒸发部410沿压缩机200的周向间隔设置，多个热管400的冷凝部420沿储液器300的周向间隔设置，加热棒1000位于相邻冷凝部420之间。
多个热管400可以均由导热安装板500固定。通过设置多个热管400，使压缩机200与多个蒸发部410接触导热，储液器300与多个冷凝部420接触导热，进一步加强了蒸发部410对压缩机200的冷却效果，并加强了冷凝部420对储液器300中的回气温度的提升效果，促进压缩机200和储液器300之间的热量传递。
根据本公开实施例的空调室外机1的其他构成例如室外换热器800和室内换热器700等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。
例如，采用本申请中空调室外机1的空调器，通过使用压缩机200、冷凝器、膨胀阀和蒸发器来执行制冷循环。制冷循环包括一系列过程，涉及压缩、冷凝、膨胀和蒸发，并向已被调节和热交换的空气供应制冷剂。
压缩机200压缩处于高温高压状态的制冷剂气体并排出压缩后的制冷剂气体。所排出的制冷剂气体流入冷凝器。冷凝器将压缩后的制冷剂冷凝成液相，并且热量通过冷凝过程释放到周围环境。
膨胀阀使在冷凝器中冷凝的高温高压状态的液相制冷剂膨胀为低压的液相制冷剂。蒸发器蒸发在膨胀阀中膨胀的制冷剂，并使处于低温低压状态的制冷剂气体返回到压缩机200。蒸发器可以通过利用制冷剂的蒸发的潜热与待冷却的材料进行热交换来实现制冷效果。
空调室外机1为空调器的室外单元，即制冷循环的包括压缩机200和室外热交换器的部分，室内单元包括室内热交换器，并且膨胀阀可以提供在室内单元或室外单元中。室内热交换器和室外热交换器用作冷凝器或蒸发器。当室内热交换器用作冷凝器时，室外热交换器用作制热模式的加热器，当室内热交换器用作蒸发器时，室外热交换器用作制冷模式的冷却器。
在本说明书的描述中，参考术语“具体实施例”、“具体示例”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公开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。
尽管已经示出和描述了本公开的实施例，本领域的普通技术人员可以理解：在不脱离本公开的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本公 开的范围由权利要求及其等同物限定。
