具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描 述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考图1-图11描述根据本发明第一方面实施例的换热组件2。
如图1-图11所示，根据本发明第一方面实施例的换热组件2，包括：换热组件2包括换热芯体21和离心风机22。
其中，换热芯体21包括第一集流管211、第二集流管212和多个换热管213。换热管213的一端与第一集流管211相连，换热管213的另一端与第二集流管212相连接，且第一集流管211的内腔与第二集流管212的内腔通过换热管213的内腔相连通。冷媒(或其它流体)可以从第一集流管211进入到换热管213内，并流入到第二集流管212。
其中，换热芯体21配置成具有孔部的形状，换热管213围绕孔部设置，孔部的轴线沿左右方向延伸，多个换热管213沿左右方向相隔开一定距离设置，换热管213具有靠近孔部的内部边缘以及远离孔部的外部边缘，换热管213从内部边缘至外部边缘方向上的尺寸大于换热管213沿左右方向的尺寸，至少部分相邻的换热管213之间存在间隙。
例如，可以将换热管213折弯成环绕一个中心轴线延伸的形状，更具体地将换热管折弯成环形，此时，换热管所环绕的中心部位为换热芯体的孔部。其中，换热管的环形可以为连续的且具有缺口的环形，也就是说，换热管的两端之间可以具有间隙，当然换热管的两端之间也可以不具有间隙。
这里，由于换热管213需要与第一集流管211和第二集流管212相连，因此，优选地，换热管213折弯成具有缺口的环形，即换热管213的环形为不封闭的环形。换热管213包括沿换热芯体21的厚度方向(例如图1中所示的离心风机22的轴向方向，即左右方向)间隔布置的多个，优选地，可以在相邻的换热管213之间设置翅片。
离心风机22设置在孔部，且离心风机22朝向间隙出风。也就是说，离心风机22朝向相邻的换热管213之间的间隙出风。
离心风机22置于换热芯体21的孔部中，换言之，离心风机22由换热芯体环绕，离心风机22轴向(例如图1中所示的左右方向)进风且朝向换热芯体四周出风。
其中，第一集流管211和第二集流管212中的其中一个用于使制冷剂可以均匀地分配并流入多个换热管213中，另一个是用于将在换热管213中换热后的制冷剂汇集到一起。
当换热组件2工作时，制冷剂从第一集流管211或第二集流管212流入换热管213内，同时，在离心风机22的作用下，空气沿离心风机22的轴向方向(例如图1中所示的左右方向)被吸入，然后再沿垂直于离心风机22轴向的方向向四周吹出，由于换热芯体环绕离心风机22，从离心风机22吹出的空气穿过相邻的换热管之间的间隙，通过与换热管213内流动的制冷剂进行热交换，制冷剂吸收空气中的热量，使空气的温度降低，以实现制冷。
根据本发明实施例的换热组件2，换热芯体21配置成中间形成有孔部的结构，换热管 围绕所述孔部的周向延伸，这样可以在不改变换热芯体厚度(例如图1中所示的换热芯体沿左右方向的厚度)的前提下，增大换热芯体的换热面积，换言之，可以在满足换热性能的前提下，减小换热芯体的厚度，节省换热芯体安装所需的空间，从而提高制冷设备100的有效容积，即增大制冷设备100中制冷间室101的容积。另外，减少换热芯体的厚度，相当于减少换热管213的数量，从而可以使换热芯体内的制冷剂的分配更加均匀。
另外，结合图1至图10，本申请中的换热管213从内部边缘至外部边缘方向上的尺寸大于换热管213沿左右方向的尺寸，可以有效地方便气流通过相邻的换热管213之间的间隙，从而提高换热的效果，而且对于气流阻碍小，便于实现气流顺畅地通过换热芯体。
在本发明的一些实施例中，第一集流管211和第二集流管212并排布置，以利于第一集流管211和第二集流管212与外部管路(例如制冷剂的进口管215和出口管216)相连接。例如，第一集流管211和第二集流管212并排布置在换热器的底部，且第一集流管211和第二集流管212的轴线沿上下方向延伸。第一集流管211与制冷剂的进口管215相连，且第二集流管212与制冷剂的出口管216相连。
在本发明的一些实施例中，换热组件2还包括第一翅片2141，相邻的换热管213之间的间隙处设置有第一翅片2141，且第一翅片2141随换热管213同向延伸，第一翅片2141具有波峰和波谷，波峰与相邻换热管213中的一个相接触，波谷与相邻换热管213中的另一个相接触。也就是说，第一翅片2141在相邻的两个换热管213之间周期性的起伏变化，从而形成交错的波峰和波谷，其中，波峰连接相邻的两个换热管213中的一个，而波谷连接相邻的两个换热管213中的另一个，因此，第一翅片2141与换热管之间形成了气流的通道，从而使得气流可以从通道中通过，实现换热。
进一步地，如图，第一翅片2141具有靠近孔部的内边缘。
其中，在沿左右方向上的投影中，第一翅片2141的内边缘至少部分伸出换热管213的内部边缘，第一翅片2141的内边缘伸出换热管213的内部边缘，可以有效地提高换热的效果。
当然，第一翅片2141的内边缘是否伸出换热管213的内部边缘并不影响本发明技术方案的实现，因此，第一翅片2141的内边缘也可以是至少部分不伸出换热管213的内部边缘。
同样地，第一翅片2141还具有远离孔部的外边缘；
其中，在沿左右方向上的投影中，第一翅片2141的外边缘至少部分伸出换热管213的外部边缘；
当然，第一翅片2141的外边缘也是否伸出换热管213的外部边缘，并不影响本发明技术方案的实现，因此，第一翅片2141的外边缘也可以是至少部分不伸出换热管213的外部边缘。
另外，本发明中至少可以包括如下的一些技术方案：
第一翅片2141的外边缘伸出换热管231的外部边缘，第一翅片2141的内边缘不伸出换热管231的内部边缘；
第一翅片2141的外边缘不伸出换热管231的外部边缘，第一翅片2141的内边缘伸出换热管231的内部边缘；
第一翅片2141的外边缘伸出换热管231的外部边缘，第一翅片2141的内边缘伸出换热管231的内部边缘；
第一翅片2141的外边缘不伸出换热管231的外部边缘，第一翅片2141的内边缘不伸出换热管231的内部边缘。
在本发明的一些实施例中，翅片214的两侧(例如图1中所示的翅片沿换热器的径向方向的两端)分别伸出换热管213的内侧边沿和外侧边沿。由此，可以有效增大换热器空气侧(即翅片)的换热面积，提高换热器的储冰和储霜容积，使得换热器整体不容易堵住；同时，由于翅片214突出，化霜排水时，水不容易粘附，便于排出；从而可以进一步提高换热效率。
在本发明的一些实施例中，换热芯体21还包括边板217，边板217与与其相邻的换热管213的相连接，或边板217与与其相邻的换热管213之间设置有第二翅片2142，第二翅片2142的至少部分与边板217相连接，第二翅片2142的至少部分与换热管213相连接。
进一步地，换热芯体21配置成大体轮廓为圆环形、椭圆环形或多边环形；换热管213从内部边缘至外部边缘的宽度为16～32mm；第一翅片2141的FPI(Fin Per Inch)值为2～16；第一翅片2141为不开窗结构；换热管213为多通道扁管。
换热芯体21可以配置成大体轮廓为圆环形、椭圆环形或多边环形。也就是说，换热芯体21可以呈圆形或椭圆形的环状，换热芯体21也可以配置成多边形的环状，从而可以使换热芯体21呈圆环形、椭圆环形或多边环形，以便于环绕离心风机。由此，可以根据实际情况(例如安装位置、安装空间等)对换热器适应性设计。
其中，在沿前后方向的投影中，离心风机22的左端和右端中的至少一个伸出换热芯体21的端面；或，在垂直于左右方向的一个方向的投影中，离心风机22的左端和右端中的一个与换热芯体21的端面齐平，且离心风机22的左端和右端中的另一个伸出换热芯体21的端面。
也就是说，在沿上下方向或者前后方向的投影中：
离心风机22的左端伸出换热芯体21的左端面，离心风机22的右端端伸出、短于、齐平于换热芯体21的右端面；或
离心风机22的左端端伸出、短于、齐平于换热芯体21的左端面，离心风机22的右端 伸出换热芯体21的右端面。
在本发明的一些实施例中，换热芯体21配置成大体轮廓为圆环形。
如图1，第一集流管211包括相对设置的第一板部2111和第二板部2112，第一板部大体呈平板状，第二板部具有大致呈弧形的横截面，其中，横截面为第二板部被沿左右方向延伸的平面所截得到的截面。第一板部具有多个第一插孔，多个第一插孔沿左右方向相隔开一定距离设置；第二集流管212包括相对设置的第三板部2121和第四板部2122，第三板部大体呈平板状，第四板部具有大体呈弧形的横截面，其中横截面为第四板部被沿左右方向延伸的平面所截得到的截面。第三板部具有多个第二插孔，多个第二插孔沿左右方向相隔开一定距离设置；第一集流管211和第二集流管212并排设置，第二板部与第四板部相接触或第二板部与第四板部相隔开一定距离。
进一步地，换热管213大体轮廓呈具有缺口的圆环形，换热管213具有第一端21301和第二端21302，在第一端和第二端之间形成缺口，换热管213的第一端穿过第一插孔并与第一集流管211相连接，换热管213的第二端穿过第二插孔并与第二集流管212相连接。
有利地，换热管213相邻的换热管213之间的间隙处设有第一翅片2141，第一翅片2141随换热管213同向延伸。
进一步地，第一翅片2141具有波峰和波谷，波峰与相邻换热管213中的一个相接触，波谷与相邻换热管213中的另一个相接触，在沿前后方向的投影中翅片214的内边缘伸出换热管213的内部边缘且翅片214的外边缘伸出换热管213的外部边沿。
有利地，换热芯体21还设置有边板217，边板217的整体轮廓与换热管213的整体轮廓大体相同，边板217设置在位于最左端的换热管213的左侧和/或边板217设置在位于最右端的换热管213的右侧，边板217与与其相邻的换热管213之间设置有第二翅片2142，第二翅片2142的至少部分与边板217相焊接，且第二翅片2142的至少部分与与其相邻的换热管213相焊接。
进一步地，孔部的轴线沿左右方向延伸，离心风机22的轴线沿左右方向延伸，且离心风机22的轴线与换热芯体21的轴线重合；离心风机22的出口的至少一部分朝向间隙，在沿前后方向的投影中离心风机22的左端伸出换热芯体21的左端面、离心风机22的右端伸出换热芯体21的右端面。
另外，第一集流管211的轴线和第二集流管212的轴线均沿前后方向延伸，相邻两个换热管213之间设有翅片214，
其中，在沿前后方向的投影中翅片214的内边缘伸出换热管213的内部边缘且翅片214的外边缘伸出换热管213的外部边沿；或相邻的两个换热管213之间设有翅片214，在沿前后方向的投影中翅片214的内边缘不伸出换热管213的内部边缘且翅片214的外边缘不 伸出换热管213的外部边沿。
如图1-图3所示，换热芯体21可以由单个换热芯体构成，且单个换热芯体21折弯成圆环形，具体地，当单个换热芯体21的换热管呈具有缺口的环形时，从而使单个换热芯体呈圆环形。单个换热芯体21的第一集流管211和第二集流管212彼此并排，进一步地，翅片214沿换热芯体21的径向延伸，且在沿换热芯体21的径向方向上，翅片214的尺寸大于换热管213的尺寸。由此，可以使换热芯体的结构最为紧凑，最大限度地减小换热芯体的安装空间，增大换热面积，提高制冷效率和空间利用率。
在本发明的一些示例中，如图4-图10所示，诸换热管在大致相同位置处具有多个换向段2131，也就是说，换热芯体具有多个换热管，每个换热管均具有多个换向段，且多个换热管的多个换向段在沿换热管延伸方向的位置大致相同。换言之，多个换热管的每一个换向段一一对应。换热芯体在多个换向段2131处折弯以形成多边环形。例如，换热管可以通过分别在多个换向段处多次折弯成三角形、四边形、五边形、六边形等等的环状。由此，可以根据实际情况(例如安装位置、安装空间等)对换热芯体的形状适应性设计。这里，换热管在换向段的折弯角度可以灵活设置，从而有利于根据压缩机仓结构进行匹配设计。
另外，由于换热管213经多次折弯形成，换向段两侧的换热管213呈角度布置，结构较紧凑，因此，优选地，相邻的两个换热管的换向段之间不布置翅片，以简化换热芯体的结构，便于加工制作。
进一步地，所述换热管包括至少三个平直段和至少两个换向段，且所述换向段连接在相邻的两个所述平直段之间。这里，如果将换热芯体折弯成N边形，则换热管具有N个平直段和N-1个换向段。在换热管折弯之前，至少一个换向段相对于平直段扭转预定角度，且相邻的扭转的换向段之间未设置所述翅片，也就是说，在相邻的两个换热管上相邻的两个扭转的换向段之间不设置翅片。由此，可以方便在换向段处折弯换热管，省力。例如图4中所示的换热芯体的换热管在折弯前，可以将换向段扭转约90°然后再折弯。
如图，换热管213包括环绕孔部设置的多个平直段2132，在环绕孔部的方向上多个平直段依次由换向段连接，以使换热芯体21大体轮廓呈多边环形。换向段2131绕换热管213的长度方向相对于平直段扭转预定角度，多个换热管213在大致相同位置处具有换向段；或相邻的平直段通过换向段圆滑过渡连接。
如图，在本发明的一个具体示例中，换热芯体21大体轮廓呈菱形。
第一集流管211和第二集流管212的横截面(即第一集流管211/第二集流管212被沿上下方向延伸的平面所截的得到的截面)为圆形，第一集流管211与第二集流管212相接触或第一集流管211与第二集流管212相隔开一定距离设置；第一集流管211设置有多个第三插孔，多个第三插孔沿左右方向相隔开一定距离设置，第二集流管212设置有多个 第四插孔，多个第四插孔沿左右方向相隔开一定距离设置；换热组件包括多个换热管213，换热管213的一端穿过第三插孔并与第一集流管211相连，换热管213的另一端穿过第四插孔并与第二集流管212相连。

有利地，在本发明的一个具体示例中，第一集流管211和第二集流管212并排设置，第一集流管211和第二集流管212位于大体轮廓呈菱形的换热芯体21的长轴方向的一端，至少一个换向段位于大体轮廓呈菱形的换热芯体21的长轴方向的另一端，以及至少两个换向段位于大体轮廓呈菱形的换热芯体21的短轴方向的两端；其中，位于长轴方向另一端的换向段绕换热管213的长度方向相对于平直段扭转预定角度，位于短轴方向两端的换向段使相邻的平直段圆滑过渡连接；相邻的两个换热管213的相对的平直段之间设有第一翅片 2141，相邻的两个换热管213的位于长轴方向的另一端的管段之间没有设置第一翅片2141，相邻的两个换热管213的位于短轴方向的两端的管段之间设置有第一翅片2141；换热芯体21还包括边板217，边板217设置在位于最左侧的换热管213的左侧和/或边板217设置在位于最右侧的换热管213的右侧，边板217与与其相邻的换热管213之间设有第二翅片2142，第二翅片2142的至少部分与边板217焊接固定，且第二翅片2142的至少部分与换热管213焊接固定，位于长轴方向另一端的换向段处没有设置边板217；
在本发明的另一个具体示例中，第一集流管211和第二集流管212并排设置，第一集流管211和第二集流管212位于大体轮廓呈菱形的换热芯体21的短轴方向的一端，至少一个换向段位于大体轮廓呈菱形的换热芯体21的短轴方向的另一端，至少两个换向段位于大体轮廓呈菱形的换热芯体21的长轴方向的两端；其中，位于短轴方向另一端的换向段使相邻的平直段圆滑过渡连接，位于长轴方向两端的换向段绕换热管213的长度方向相对于平直段扭转预定角度；相邻的两个换热管213的相对的平直段之间设有第一翅片2141，相邻的两个换热管213的位于长轴方向两端的管段之间没有设置第一翅片2141，相邻的两个换热管213的位于短轴方向的另一端的管段之间设置有第一翅片2141；换热芯体21还包括边板217，边板217设置在位于最左侧的换热管213的左侧和/或边板217设置在位于最右侧的换热管213的右侧，边板217与与其相邻的换热管213之间设有第二翅片2142，第二翅片2142的至少部分与边板217焊接固定，且第二翅片2142的至少部分与换热管213焊接固定，位于长轴方向两端的换向段处没有设置边板217；
另外，在本发明中，孔部的轴线沿左右方向延伸，离心风机22的轴线沿左右方向延伸，且离心风机22的轴线与换热芯体21的轴线重合；离心风机22的出口的至少一部分朝向间隙，在沿前后方向的投影中离心风机22的左端伸出换热芯体21的左端面、离心风机22的右端伸出换热芯体21的右端面。
这里，需要说明的是，由于本实施例的换热芯体的换热管为扁管，且扁管的长度方向为环绕离心风机轴线的方向，扁管的厚度方向为平行于离心风机轴线的方向，扁管的宽度方向为离心风机四周出风的方向，因此，将扁管扭转90°后沿平行于扁管的宽度方向折弯扁管(垂直于扁管的厚度方向折弯扁管)可以更加省时省力，且折弯效果好。
在本发明的一些实施例中，所述换热管为扁管，所述第一集流管和第二集流管具有矩形或圆形横截面，由此，可以简化换热管结构，使换热芯体的结构更为紧凑。
进一步地，如图1-图3所示，换热管213为扁管，换热管213的宽度D在16mm-32mm的范围内。这里，换热管213的宽度D是指，在垂直于离心风机轴线的投影平面上，换热管213的垂直于其延伸方向(换热管213的长度方向)的尺寸，即，换热管的环宽。例如，当换热芯体为圆环形时，换热管的宽度指，换热管在沿换热芯体的径向方向上的宽度。
这里，需要说明的是，单个换热芯体21的换热能力可以通过设置不同数量的扁管来实现，当然，换热芯体的总体厚度需要根据安装空间和制冷量需求确定，也就是说，换热芯体的厚度是根据实际安装空间及能力要求设置不同数量的换热管213来确定的。
其中，结合图1-图3，相邻的换热管213之间设置多个翅片214，且翅片214沿换热管213的宽度方向延伸，且在沿垂直于气流的流向方向上，相邻的翅片214之间呈V型布置，翅片214与换热管213的外周壁之间限定出空气流通的气流通道。
优选地，翅片214在单位英寸的密度在2-16的范围内。也就是说，在1英寸的长度内翅片214的个数可以在2-16的范围内。由此，可以保证并提高换热芯体的换热效率。
在本发明的一些实施例中，换热芯体可以为微通道换热器，微通道换热器可以强
该换热芯体与离心风机配合使用，在微通道厚度较小的情况下，仍然有一个较大的换热面积，达到换热能力要求；相对于传统换热芯体，节省大量空间，提高冰箱有效容积；
换热器采用折弯成环形的方式，可适应压缩机仓结构进行匹配设计；
通过优化环形换热器折弯尺寸、翅片密度等，可有效地改善换热芯体的排水；
采用两根翅片并排放置、翅片内径方向和外径方向均突出的“overhang”形式，有效增大了空气侧换热面积，提高微通道换热芯体储冰和储霜容积，整体不容易堵住；另外，翅片突出，化霜排水时，水不容易粘附，便于排出；
采用中间进风和四周出风的方式，风量分布均匀，温度均匀性更好；
换热芯体厚度小，扁管数量小，换热芯体内部冷媒分配更加均匀；
换热芯体的集流管采用“D”型管的形式，在扁管方向减小了集流管所占的空间，从而增大了换热面积，增强换热效果。
环形微通道换热芯体和离心式风机匹配作为一个换热器组件；
采用扁管折弯成圆形或接近圆形的折弯方式，做成一个环形换热器；
换热器的折弯尺寸不限，可根据实际安装空间的要求灵活变动，扁管的宽度可以从16mm-32mm，翅片密度可以从2-16；
扁管的根数不限，根据实际空间及换热能力要求进行设计。
环形换热芯体的工作原理如下图所示：热空气由离心风机从冷冻室或冷藏室的中部吸风通过环形换热芯体变成冷空气，分别从上部和下部进入冷冻室或冷藏室。从示意图中可以看出，环形换热芯体充分利用四周的空间，增大换热面积，在换热性能满足要求的前提下，厚度减小，大大节省了换热芯体安装所需空间。同时，中间吸风、四周出风的空气循环模式使得冷空气分布更加均匀，冷冻室或冷藏室室温一致性更好。
为一款环形折弯微通道换热芯体与离心风机组件图。环形微通道换热芯体由扁管、翅片、集流管及进出口管组成，通过折弯成环形来形成如图所示的环形换热芯体。微通道换 热芯体的折弯尺寸可根据实际安装空间的要求进行调整，整个换热器的安装角度可根据实际情况进行安装。扁管的宽度可以从16mm-32mm，翅片密度可以从2-16。采用两根翅片并排放置、翅片内径方向和外径方向均突出的“overhang”形式，有效增大了空气侧换热面积。换热器的厚度可以根据实际安装及能力要求设置不同数量的扁管根数。放置方式如图1所示。
如图1所示，为一款菱形折弯微通道换热芯体与离心风机组件图。菱形微通道换热芯体由扁管、翅片、集流管及进出口管组成，通过如图所示的折弯方式折3次形成入股所示的菱形换热芯体。微通道的折弯角度可根据实际安装空间的要求灵活变动，整个换热器的安装角度可根据实际情况进行安装。扁管的宽度可以从16mm-32mm，翅片密度可以从2-16。换热器的厚度可以根据实际安装及能力要求设置不同数量的扁管根数。根据实际空间有图1(a)和图1(b)两种放置方式。
为一款菱形折弯微通道换热芯体与离心风机组件图。与方案一不同的是，换热芯体采用两种折弯方式，折弯1和折弯3是同一种，折弯2的折弯方式和方案一的一样。这种折成菱形的方式可以增加一部分换热面积，加强换热。
菱形换热芯体的工作原理如下图所示，热空气由离心风机从冷冻或冷藏室的中部吸风通过菱形换热芯体的变成冷空气，分别从上部和下部进入冷冻或冷藏室。从示意图中可以看出，菱形换热芯体充分利用四周的空间，增大换热面积，在换热性能满足要求的前提下，厚度减小，大大节省了换热芯体安装所需空间。同时，中间吸风，四周出风的空气循环模式使得冷空气分布更加均匀，冷冻室或冷藏室温一致性更好。
根据本发明第二方面实施例的制冷设备100，包括：箱体1和根据本发明上述第一方面实施例的换热组件2。其中，本发明实施例的制冷设备100可以为冰箱或冷柜等等。换热组件为冰箱或冷柜中的换热芯体组件，换热芯体作为冰箱或冷柜中的换热芯体。
具体地，如图11所示，箱体1内具有制冷间室101和风道102，风道102与制冷间室101连通；换热组件2设在风道102内。离心风机22用于驱动风道102和制冷间室101内的空气循环流通，用于为制冷间室101提供冷量，用于冷冻或冷藏食物，也可以通过风道102实现不同间室之间的气流循环。
根据本发明实施例的制冷设备100，通过设置上述第一方面实施例的换热组件2，从而提高了制冷设备100的整体性能。
进一步地，如图11所示，风道102具有进风口105和至少一个出风口(例如下文中所述的上风口103、下风口104)，出风口(上风口103和下风口104)和进风口105均与制冷间室101相连并连通，例如图11所示，风道具有上风口103、下风口104和进风口105，且上风口103和下风口104均为出风口，其中，上风口包括一个或间隔布置的多个，下风 口包括一个或间隔布置的多个。
进一步地，当风道具有多个出风口时，多个出风口可以环绕进风口105布置。
离心风机22通过进风口105将制冷间室101内的空气抽吸到风道102内，且风道102内与换热芯体进行了热交换后的空气分别通过所述至少一个出风口(例如图11中所示的上风口103和下风口104)进入到制冷间室101内。
然而相关技术中的制冷设备100在工作的过程中，通常是轴流风机从制冷间室101的底部将制冷间室101内的空气抽吸到风道102内，且风道102与换热芯体换热后的冷空气从制冷间室101的顶部进入制冷间室101。
本发明实施例的制冷设备100，离心风机22通过进风口105从制冷间室101(冷冻或冷藏室)的中部吸风，吸入的空气进入风道102内，且吸入的空气通过换热芯体的变成冷空气，再分别从上风口103和下风口104进入制冷间室101。由此，本实施例的制冷设备100的换热芯体可以充分利用风道102四周的空间，有效增大换热面积，在换热性能满足要求的前提下，减小换热芯体的厚度，大大节省了换热芯体安装所需空间。同时，中间吸风、四周出风的空气循环模式可以使得冷空气分布更加均匀，使得制冷间室101内的温度一致性更好。
使用该种换热芯体需要在冰箱冷柜内部设置一个较大的风道，配合轴流风机使用，占用较大箱体内容积。工作原理如下图所示，空气由轴流式风机从冷冻室或冷藏室底部吸风经过换热芯体换热变成冷空气又从顶部进入到冷冻或冷藏室。
