本申请基于申请号为202210431353.1、申请日为2022年04月22日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及换热器技术领域，尤其涉及一种换热装置和换热系统。
背景技术
目前微通道换热器作为蒸发器在空调系统中运行时，由于每根扁管之间的分液不可能完全均匀，因此会造成蒸发器出口带有大量的未蒸发液体进入系统，导致冷媒流量减小，换热效率下降，并且可能导致压缩机损坏等不良后果。
现有横插翅片换热器，第二组件位于芯体两侧，制冷剂从多个进口进入换热器，经过换热后进入出口第二组件，由于第二组件腔体较大，部分未蒸发的液态制冷剂由于重力作用会落入出口第二组件底部，气态制冷剂在第二组件上部空间，液态制冷剂在压差驱动下与气态制冷剂混合被带出出口管，进入压缩机，从而影响压缩机的正常与运转，也降低了换热效率。
微通道换热器作为冷凝器或蒸发器已经普遍用在空调系统中，换热器通常包括多个换热管、进口集管和出口集管，当空调系统工作时候，相关技术中，当换热器作为蒸发器使用时，换热管为竖直放置，进口集管和出口集管则为水平放置，气液两相的制冷剂从制冷剂流入进口集管内后流向各个换热管，再从出口集流管流出，在重力作用下，气液两相制冷剂容易在出口集流管内产生气体和液体分层现象，液态制冷剂在压差驱动下与气态制冷剂混合被带出，因而影响了换热系统运行的可靠性，降低了换热机组的使用寿命，影响了换热系统的换热效率。

具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
参阅图1，本实施例提供一种换热装置，包括：换热管10、第一组件20、输送管30、进出口管31和第一管40，换热管10包括换热通道，换热管10的数量为多个，均可用于与外接换热，多个换热管10在第一组件20长度方向上间隔布置，换热管10长度方向上的第一端与第一组件20直接连接或间接连接，第一组件20包括第一腔，第一腔与多个换热通道连通；输送管30包括输送通道，输送通道与多个换热通道连通；进出口管31为多个，一个进出口管31与至少一个换热管10连通，进出口管31均与输送通道连通；至少部分第一管40位于第一腔内，第一管40包括第二腔，至少部分第二腔位于第一腔内，且位于第一腔内的该至少部分第二腔与第一腔不连通。
换热系统可以有多种不同的工作模式，当该换热装置在系统中作为制冷剂的蒸发器工作时，制冷剂可以沿着输送管30的输送通道流入进出口管31，然后进一步流入多个换热管10的换热通道内与空气进行换热，然后流入第一组件20的第一腔内。其中从输送通道过来的部分制冷剂会流入第一管40的第二腔内，这部分制冷剂的温度跟第一组件20内的制冷剂温度相比，相对更高，因此在受重力作用，积聚在第一组件20的液态制冷剂能被该部分制冷剂加热。由于至少部分第一管40位于第一腔内，因此，第一管40能够加热位于第一腔内的液态制冷剂，从而有利于减少第一组件20中液态制冷剂的积聚，减少液态制冷剂的流出。
其中，第一管40与输送管30连接，从而输送通道内的制冷剂可以流入第一管40的第二腔内，第一管40也可以与压缩机1的出口3连通，从而由压缩机1流出的高温制冷剂可以流入第一管40的第二腔内。
参阅图1，在第一管40与输送管30连通的实施例中，当换热系统冬天跑制热工况时，该换热装置作为蒸发器运行，节流后的两相态制冷剂从输送管30进入多个换热管10，输送管30通过分液头进一步将制冷剂分配给各进出口管31，由于分液段压降较大，因此流入第一管40的第二腔内的制冷剂温度会大于第一组件20的第一腔内制冷剂的温度，使得积聚在第一腔内的液态制冷剂被第一管40内的高温制冷剂加热，使其蒸发，减少了第一组件20中液态制冷剂的流出。
当换热系统夏天跑制冷工况时，该换热器作为冷凝器运行，高温高压气态制冷剂从第一组件20进入换热管10，经过与空气热交换后形成高温高压液态制冷剂流入输送管30，此时，第一组件20内的第一管40内部的液态制冷剂被第一组件20内的高温气态制冷剂加热气化并被封在第一管40内，由于第一组件20内设置有第一管40，因此减少了第一组件20的内容积，有利于提升该换热装置的换热效率，因此提升了换热装置的换热效率。
在一些实施例中，第一管40与输送管30直接连接或间接连接，第二腔与输送通道连通，从而输送通道内的高温的制冷剂能够流入第二腔内。在一些实施例中，第一管40的一端与输送管30连接，另一端伸入第一腔内，且第一腔相对第二腔密封。
本实施方式进一步提供一种换热系统，包括：压缩机1、制冷剂和上述实施例中的换热装置；第一组件20的长度方向与水平方向成角度，如图1-图7中，第一组件20的长度方向与水平方向垂直。当然，第一组件20的长度方向与水平方向之间的夹角也可以是85°、80°等。
其中，第一组件20包括第一端盖和第二端盖，第一端盖和第二端盖沿第一组件20长度方向设置，第一端盖在竖直方向上高于第二端盖，第一管40与第二端盖直接连接或间接连接，也就是说第一管40通过第二端盖连接在第一组件20上。
换热装置作为蒸发器工作时，部分制冷剂由输送通道流向多个换热通道，再流向第一腔内，另一部分制冷剂由输送通道流向第二腔，第二腔内制冷剂的平均温度高于第一腔内制冷剂的平均温度，从而达到加热第一腔内制冷剂的目的。
在一些实施例中，第一腔包括第一容纳腔和第二容纳腔，第一容纳腔和第二容纳腔连通，第一容纳腔与换热管10的换热通道连通；至少部分第二腔位于第二容纳腔内，且位于第二容纳腔内的该至少部分第二腔与第二容纳腔不连通。
在一些实施例中，可以在第一腔内设置一个隔板，从而将第一腔分割成第一容纳腔和第二容纳腔，也可以将第一组件20分成两部分，每一部分均形成腔室。
例如：第一组件20包括第一管件21和第二管件22，第一容纳腔形成于第一管件21，第二容纳腔形成于第二管件22。第一管件21和第二管件22可以通过连接管连接，以实现第一容纳腔和第二容纳腔的导通。
在一些实施例中，参阅图2，输送管30上包括第一连通孔和第二连通孔，第一管40的一端在第一连通孔与输送管30直接连接或间接连接，第一管40的另一端在第二连通孔与输送管30直接连接或间接连接，至少部分第一管40位于第二容纳腔内；制冷剂能够从第一连通孔流入第一管40的第二腔内，并从第二连通孔流出至输送管30的输送通道内。也就是说， 第一管40的两端均与输送管30连接，这样设置能够使得第一管40内的制冷剂的流动性更好，从而提高加热效果，减少液态制冷剂的流出，提升了换热系统的可靠性。
进一步地，参阅图3，第一连通孔通向第二连通孔的部分输送管30设置有第一单向阀51，以利于换热装置实现系统不同模式下的工作状态，当换热装置在制冷剂为蒸发器工作情况下，第一单向阀51截止，当换热装置在制冷剂为冷凝器工作情况下，第一单向阀51导通，以使制冷剂能够从第二连通孔在输送管30内单向流动至第一连通孔；由此，输送管30内的制冷剂在流向换热管10之前只能从第一管40内经过，从而使得第一管40内的制冷剂具有良好的加热效果，有利于减少第一组件中液态制冷剂的流出，提升换热系统换热效率。
进一步地，参阅图2，第一管40设置有第二单向阀52，在换热系统中，当换热装置在蒸发器工作模式下，以使制冷剂能够从第一连通孔在第一管40内单向流动至第二连通孔，由此，在其他模式下，制冷剂反向流动时，制冷剂不从第一管40内经过。
参阅图3，换热系统还包括节流装置60，节流装置60与输送管30连通，沿输送管30内的制冷剂流动方向，节流装置60位于输送管30的下游，节流装置60相较于换热管10的制冷剂出口通道更靠近换热管10的制冷剂入口通道。通过在输送管30上设置节流装置60，能够进一步增大输送管30和换热管10之间的压差，从而提高换热系统的性能。
在一些实施例中，换热装置还包括第二组件70，所述第二组件70包括第三壁，第二组件70还包括第三腔，围成第三腔的壁包括第三壁。
在一些实施例中，换热管10长度方向上的第二端与第二组件70直接连接或间接连接，第一腔与多个换热通道连通；换热通道和输送通道均与第三腔连通。第二组件70可将多个进出口管31输送的制冷剂汇集，然后输送到各个换热管10内。
示例地，第一管件21内设置有第一隔板201，第一容纳腔包括第一子腔室和第二子腔，至少部分第一隔板位于第一子腔室和第二子腔室之间，第二组件70内设置有第二隔板701，第三腔包括第三子腔室和第四子腔室，至少部分第二隔板701位于第三子腔室和第四子腔室之间，至少一个换热管10的换热通道连通第二子腔室和第四子腔室，其余换热管10的换热通道连通第一子腔室和第三子腔室。
在一些实施例中，输送管30包括第一输送管32和第二输送管33，第一输送管32的输送通道连通第二子腔室，第二组件70包括围成第三子腔室的第三子壁和围成第四子腔的第四子壁，第二输送管33的一端与部分第三子壁直接或间接连接，第二输送管33的另一端与部分第四子壁直接或间接连接，第二输送管33的输送通道连通第四子腔室与第三子腔室。
示例地，第一管件21内设置有第一隔板201，第一隔板201将第一容纳腔分成两个相对密封的第一子腔室和第二子腔室，第二组件70内设置有第二隔板701，第二隔板701将第三腔分成两个相对密封的第三子腔室和第四子腔室，至少一个换热管10的两端分别连通第二子腔室和第四子腔室，其余换热管10的两端分别连通第一子腔室和第三子腔室；也就是说，本实施例中，将换热管10代替了一部分输送管30，从而提升了换热装置的可靠性，而且第一子腔室和第二子腔室之间的第一隔板201可以传导热量，从而进一步减少第一子腔 内制冷剂液化的问题。输送管30包括第一输送管32和第二输送管33，第一输送管32连通第二子腔室，第二输送管33的一端连通第四子腔室，另一端与第三子腔室连通。
进一步地，参阅图5，第一输送管32上包括第一连通孔和第二连通孔，第一管40的第二腔的一端在第一连通孔与第一输送管32连通，第一管40的第二腔的另一端在第二连通孔与第一输送管32连通，至少部分第一管40位于第二容纳腔内；制冷剂能够从第一连通孔流入第一管40的第二腔内，并从第二连通孔流出至第一输送管32内。
进一步地，第一输送管32设置有第三单向阀53，第三单向阀53设置为使制冷剂能够从第二连通孔在第一输送管32内单向流动至第一连通孔；第一管40设置有第四单向阀54，以使制冷剂能够从第一连通孔在第一管40内单向流动至第二连通孔。由此，第一输送管32内的制冷剂在输送换热管10之前，需要从第一管40内经过，从而使得第一管40内的制冷剂对第二管件22内制冷剂的加热效果更加稳定。在换热装置作为制冷剂的冷凝器工作时，制冷剂反向流动时，不必流经第一管40。
在一些实施例中，参阅图6，输送管30上包括第一连通孔和第二连通孔，第一管40的一端在第一连通孔与输送管30直接连接或间接连接，第一管40的另一端在第二连通孔与输送管30直接连接或间接连接，至少部分第一管40位于第二容纳腔内；制冷剂能够从第一连通孔流入第一管40的第二腔内，并从第二连通孔流出至输送管30内；第一连通孔和第二连通孔之间的管路设置有第五单向阀50，以使制冷剂能够从第二连通孔在输送管30内单向流动至第一连通孔。由此，输送管30内的制冷剂先流经第一管40，然后再流向换热管10换热，从而使得第一管40内的制冷剂对第一组件20内制冷剂的加热效果更加稳定，有利于减少换热装置的第一组件20中的液态制冷剂的流出。
在一些实施例中，参阅图7，换热系统还包括换热器5和四通阀4，四通阀4包括第一接口、第二接口、第三接口和第四接口，第一管40的一端与压缩机1的出口3连通，第一管40的另一端与第一接口连通，换热装置在作为蒸发器工作状态时，所述第一接口与所述第三接口连通，第三接口与换热器5的一个接口连通，第四接口与第一组件20的一个接口连通，第二接口与压缩机的进口2连通。在本实施例中，在压缩机1的出口3流出的制冷剂的相对其他换热器和换热装置中的制冷剂温度较高，热量损失少，从而通过第一管40的制冷剂具有良好的加热效果，有利于减少换热装置的第一组件中的液态制冷剂的流出，提升换热系统的换热效率，以及提升压缩机的可靠性。
在一些实施例中,参阅图2和图3，第一管40从第二管件22的顶壁进入第一腔，并从第二管件22的底壁从所述第一腔穿出。
在一些实施例中,参阅图4，第一管40从第二管件22的侧壁或者底壁进入第一腔，并从第二管件22的底壁从所述第一腔穿出。
在一些实施例中，参阅图2、图3、图4、图5和图7，第一管40的加热段包括螺旋管段，参阅图6，第一管40的加热段包括U形管段。由此，可以增加第一管40在第一组件20内的流通路径，从而提高加热效果。
