可选地，所述回风管的进风口和出风口都设置在所述第一管壳或所述第二管壳上。
基于前文的描述，本领域技术人员能够理解的是，在本发明前述的技术方案中，通过在第一储藏室的侧壁上设置固定孔，并将固定构件卡合到固定孔中，然后通过螺纹构件将回风管固定到固定构件上，即通过固定构件使得回风管能够被螺纹构件固定到第一储藏室的侧壁(内胆的侧壁)上。其中，固定构件与固定孔之间的卡合方式，方便了操作人员对固定构件与第一储藏室侧壁之间的安装，同时还提升了第一储藏室的侧壁(内胆的侧壁)的强度， 避免了出现第一储藏室的侧壁因安装固定构件而发生形变的情形。
进一步，通过使固定孔与出风孔连通，并在固定构件上设置有滑槽，使得固定构件能够从出风孔滑入并嵌合到固定孔中，并使第一储藏室的侧壁与固定孔相接的部分嵌入滑槽中，不仅方便了操作人员对固定构件的安装，而且还提升了第一储藏室侧壁的强度。
进一步，通过将回风管的第二出风端设置在蒸发器的前侧，将回风管的出风方向与蒸发器的正前方之间的夹角的取值范围设置为60°至85°，并在制冷室的前侧壁上设置与第二储藏室相对应的回风口，使得回风口的回风方向与回风管的出风方向之间具有60°至85°的夹角，在两股气流能够彼此对冲的同时，还避免了彼此之间串风的情形(例如回风口处的风进入回风管中)。
本领域技术人员能够理解的是，两股气流对冲时，能够将两股气流打散，相对于使未经打散的气流直接吹向蒸发器而言，能够使蒸发器的各个部分都充分地接触流动的空气，提升了蒸发器与空气的接触面积和使用效率。由于两个气流对冲时各自被打散，使得空气的流速也得到降低，延长了流动的空气与蒸发器接触的时间，从而使得蒸发器与空气之间的换热更加充分，进一步提升了蒸发器的使用效率。而60°至85°的对冲夹角能够使被打散的气流在流经蒸发器时扩散得更加均匀。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

如图1和图2所示，在本发明的一些实施例中，制冷设备包括内胆100、 形成在内胆100中的制冷室200、第一储藏室300和第二储藏室400。其中，制冷室200、第二储藏室400和第一储藏室300自下至上依次分布在内胆100中。制冷设备还包括横置地安装在制冷室200内的蒸发器500。制冷室200的前侧壁上设置有回风口201，回风口201用于使第二储藏室300内的空气进入制冷室200。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，省去第二储藏室200的设置。
进一步，在本发明的其他实施例中，本领域技术人员还可以根据需要，为制冷设备配置多个内胆100，并将制冷室200和第一储藏室300限定在不同的内胆100中。
如图2至图5所示，制冷设备还包括送风管600、回风管700、固定构件800和螺纹构件900。
如图2和图3所示，送风管600包括第一进风端601和第一出风端602，送风管600通过第一进风端601与制冷室200连通，送风管600通过第一出风端602与第一储藏室300连通。进一步，送风管600包括两个第一出风端602，送风管600通过另一个第一出风端602与第二储藏室400连通。
此外，在本发明的其他实施例中，本领域技术人员可以根据储藏室的数量，来调整第一出风端602的数量，以确保每一个储藏室对应有至少一个第一出风端602。
需要说明的是，在本发明中，送风管600的进风口形成在第一进风端601上，并且第一进风端601上设置有至少一个进风口；送风管600的出风口形成在第一出风端602，并且每一个第一出风口端602上设置有至少一个出风口。
如图4和图5所示，制冷设备还包括两个回风管700，两个回风管700大体上对称地设置在内胆100的左侧部和右侧部，以使第一储藏室300能够均匀地回风。下面以设置在内胆100的左侧部上的回风管700为例来进行详细说明。
如图2、图4和图5所示，回风管700包括第二进风端701和第二出风端702，回风管700通过第二进风端701与第一储藏室300连通，回风管700通过第二出风端702与制冷室200连通。回风管700还包括设置在第二进风端701处的固定翼703和设置在第二出风端702处的固定板704。回风管700 通过固定翼703和固定板704与内胆100固定到一起。
如图5所示，与回风管700的第二进风端701相对应地，内胆100的后侧壁(具体是第一储藏室300的后侧壁)上设置有出风孔101和固定孔102。可选地，固定孔102与出风孔101连通，并且固定孔102的尺寸小于出风孔101的尺寸，以便固定构件800能够从出风孔101滑入并嵌合到固定孔102中。
如图2所示，在装配好的状态下，回风管700的第二进风端701嵌合到出风口101中，固定构件800嵌合到固定孔102中，螺纹构件900与固定构件800拧紧到一起，从而将回风管700的固定翼703紧紧地固定到内胆100上。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，将出风孔101和固定孔102设置在内胆100的左侧壁和/或右侧壁上，并使回风管700的第二进风端701固定到内胆100的左侧壁和/或右侧壁上。
如图5和图6所示，与回风管700的第二出风端702相对应地，内胆100的底部设置有安装面103，该安装面103与蒸发器500侧面之间的夹角的取值范围为5°-30°。回风管700的固定板704与安装面103贴合到一起，可选地，固定板704与安装面103采用粘接的方式固定到一起。
如图6所示，由于安装面103与蒸发器500侧面之间的夹角的取值范围为5°-30°，使得回风管700的出风方向与蒸发器500的正前方之间的夹角α的取值范围是60°至85°。夹角α的具体取值范围可选地可以通过调整安装面103与蒸发器500侧面之间的夹角来进行调整，夹角α的具体数值可以是60°、64°、70°、73°、75°、80°等。
如图2和图6所示，在装配好的状态下，送风管600的第一进风端601位于蒸发器500的后侧，回风管700的第二出风端702位于蒸发器500的前侧，并且制冷室200的回风口201位于第二出风端702的前侧。
基于此，本领域技术人员能够理解的是，夹角α在使两股气流(从回风口201进入制冷室200内的气流和从回风管700进入制冷室200内的气流)能够彼此对冲的同时，还避免了彼此之间串风的情形(例如回风口201处的风进入回风管700中)。
本领域技术人员进一步能够理解的是，两股气流对冲时能够被打散，相对于使未经打散的气流直接吹向蒸发器500而言，能够使蒸发器500的各个 部分都充分地接触流动的空气，提升了蒸发器500与空气的接触面积和使用效率。由于两个气流对冲时各自被打散，使得空气的流速也得到降低，延长了流动的空气与蒸发器500接触的时间，从而使得蒸发器500与空气之间的换热更加充分，进一步提升了蒸发器500的使用效率。而60°至85°的对冲夹角能够使被打散的气流在流经蒸发器500时扩散得更加均匀。
下面参照图7和图8来对本发明一些实施例中，回风管700的具体结构进行详细说明。
如图7和图8所示，回风管700包括第一管壳710和第二管壳720，第一管壳710包括第一条形敞口711，第二管壳720包括第二条形敞口721。第一管壳710和第二管壳720以第一条形敞口711和第二条形敞口721彼此相对的姿态固定到一起，并因此使第一管壳710和第二管壳720限定出回风通道(图中未标记)。在回风管700被安装到制冷设备上的状态下，使第一管壳710位于第二管壳720水平方向上的一侧。
从图5、图7和图8中可以看出，第一管壳710和第二管壳720之间的衔接缝隙(图中未标记)分布在第一管壳710或第二管壳720的顶侧、底侧、前侧和后侧。具体地，该衔接缝隙分布在第二管壳720的顶侧、底侧、前侧和后侧。
如图7和图8所示，第一管壳710包括设置在第一条形敞口711边缘处的第一挡边712，第二管壳720包括设置在第二条形敞口721边缘处的第二挡边722，第一挡边712和第二挡边722彼此交叠地抵接到一起，并因此形成第一管壳710和第二管壳720之间的衔接缝隙(图中未标记)。
继续参阅图7和图8，第一挡边712包括第一内挡边7121和第一外挡边7122，第二挡边722包括第二内挡边7221和第二外挡边7222，第二内挡边7221位于第一内挡边7121的内侧，第二外挡边7222插入到第一内挡边7121和第二内挡边7121之间。
继续参阅图7和图8，第一外挡边7122上设置有多个卡槽71221，第二外挡边7222上设置有多个卡扣72221，该多个卡槽71221和多个卡扣72221扣接在一起，并因此将第一管壳710和第二管壳720完全固定到一起。
继续参阅图7和图8，第一外挡边7122在第一条形敞口711延伸方向两侧的部分上，交错布置有多个卡槽71221。第二外挡边7222在第二条形敞口721延伸方向两侧的部分上，交错布置有多个卡扣72221。
换句话说，第一管壳710上两个V形的侧边上的卡槽71221彼此不对准，即两个V形的侧边上的卡槽71221犬牙交错布置。同样地，第二管壳720上两个V形的侧边上的卡扣72221彼此不对准，即两个V形的侧边上的卡扣72221犬牙交错布置。
本领域技术人员能够理解的是，卡槽71221和卡扣72221该种犬牙交错布置形式，在不过多增加卡槽71221和卡扣72221数量的情形下，能够使第一管壳710和第二管壳720之间的固定更加牢靠。
继续参阅图7和图8，第一外挡边7122在第一条形敞口711延伸方向上的一个端部处设置有至少一个卡槽71221(优选地为一个)。第二外挡边7222在第二条形敞口721延伸方向上的一个端部处设置有至少一个卡扣72221(优选地为一个)。从图7和图8中可以看出，该一个端部为弧形结构。该至少一个卡槽71221和该至少一个卡扣72221，使得第一管壳710和第二管壳720在该一个端部处的弧形结构固定地更加牢靠。
优选地，每一个卡扣72221对应一个卡槽71221。或者，本领域技术人员也可以根据需要，使多个卡扣72221对应一个卡槽71221。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，省去卡扣72221和卡槽71221的设置，并使第一内挡边7121、第一外挡边7122、第二内挡边7221和第二外挡边7222彼此夹紧，从而将第一管壳710和第二管壳720完全固定到一起。可选地，还可以在第一内挡边7121、第一外挡边7122、第二内挡边7221和第二外挡边7222中相邻的两个挡边之间涂覆胶水，以通过粘接的方式使第一管壳710和第二管壳720完全固定到一起。
此外，在本发明的另一些实施例中，本领域技术人员还可以根据需要，使第一挡边712和第二挡边722分别保留一个挡边，并使第一挡边712和第二挡边722彼此夹紧，从而将第一管壳710和第二管壳720完全固定到一起。或者，在第一挡边712和第二挡边722之间涂覆胶水，以通过粘接的方式使第一管壳710和第二管壳720完全固定到一起。
继续参阅图7和图8，第一管壳710内设置有第一支撑筋713，第一支撑筋713用于支撑第一管壳710的侧壁。具体地，第一支撑筋713与第一条形敞口711的延伸方向垂直，以支撑第一管壳710的相对两侧。本领域技术人员能够理解的是，由于第一条形敞口711的存在，使得第一管壳710临近第一条形敞口711的两个侧边容易发生向内/向外的形变，而第一支撑筋713 能够有效地避免出现这种情况。
继续参阅图7和图8，第二管壳720内设置有第二支撑筋723，第二支撑筋723用于支撑第二管壳720的侧壁。具体地，第二支撑筋723与第二条形敞口721的延伸方向垂直，以支撑第二管壳720的相对两侧。本领域技术人员能够理解的是，由于第二条形敞口721的存在，使得第二管壳720临近第二条形敞口721的两个侧边容易发生向内/向外的形变，而第二支撑筋723能够有效地避免出现这种情况。
虽然图中并未示出，但是优选地，第一支撑筋7132被设置为半圆柱，并且第一支撑筋713的弧形面面向第一条形敞口711；第二支撑筋7232被设置为半圆柱，并且第二支撑筋723的弧形面面向第二条形敞口721。本领域技术人员能够理解的是，通过将第一支撑筋7132和第二支撑筋723设置成半圆柱并且使半圆柱的弧形面彼此相对，在保证第一管壳710和第二管壳720具有足够强度的前提下，还通过该彼此相对的弧形面有效地降低了第一支撑筋7132和第二支撑筋723的风阻。
继续参阅图7和图8，回风管700的固定翼703、固定板704、进风口705和出风口706都设置在第一管路710上，以便于操作人员将回风管700安装到内胆100上。具体地，操作人员可以先将第一管路710固定到内胆100上，再将第二管路720安装到第一管路710上。
其中，固定翼703设置在回风管700的第二进风端701处，并且大体上为直板状结构；固定板704设置在回风管700的第二出风端702处，并且大体上为弧形的板状结构。
下面参照图9来对本发明一些实施例中固定构件800的结构进行详细说明。
如图9所示，在本发明的一些实施例中，固定构件800上设置有滑槽801。在固定构件800嵌合到固定孔102中的状态下，第一储藏室300的侧壁(即，内胆100的侧壁)与固定孔102相接的部分嵌入滑槽801中，从而使得滑槽801的侧壁夹紧内胆100的侧壁，并因此使固定构件800卡到固定孔102中。
继续参阅图9，固定构件800包括位于第一储藏室300外侧(即，内胆100外侧)的固定柱802，固定柱802上设置螺纹孔8021。
如图2和图5所示，在装配好的状态下，螺纹构件900穿过固定翼703上的通孔并拧紧到螺纹孔8021中，从而将固定翼703紧固到内胆100上。 其中，螺纹构件900可以是螺钉或螺栓。
此外，在能够通过螺纹构件900将固定翼703紧固到内胆100上的前提下，固定柱802上的螺纹孔8021还可以被设置在固定柱802圆周面上的为螺纹替代。其中，螺纹构件900可以是螺母。
本领域技术人员能够理解的是，由于固定构件800的厚度远大于内胆100的侧壁的厚度，并且固定构件800与内胆100侧壁之间的配合面积较大(滑槽801所对应的区域)，使得回风管700在通过螺钉或螺栓固定到内胆100上时，不会引起内胆100的侧壁发生形变。
下面参照附图2和图5，来对本发明一些实施例中，回风管700的安装进行详细说明。
首先将固定构件800从出风口101滑进固定孔102中，并因此使滑槽801卡住内胆100的侧壁，防止固定构件800在自身重力的作用下滑落。然后将回风管700的固定翼703与固定柱802对准，再将螺纹构件900拧紧到固定柱802上。最后将回风管700的固定板704贴附在内胆100的安装面103上。
基于前文的描述，本领域技术人员能够理解的是，本发明通过使固定孔102与出风孔101连通，并在固定构件800上设置有滑槽801，使得固定构件800能够从出风孔101滑入并嵌合到固定孔102中，并使第一储藏室300的侧壁与固定孔102相接的部分嵌入滑槽801中，不仅方便了操作人员对固定构件800的安装，而且还提升了第一储藏室300侧壁的强度。
进一步，本发明还通过将回风管700的第二出风端702设置在蒸发器500的前侧，将回风管700的出风方向与蒸发器500的正前方之间的夹角的取值范围设置为60°至85°，并在制冷室200的前侧壁上设置与第二储藏室500相对应的回风口201，使得回风口201的回风方向与回风管700的出风方向之间具有60°至85°的夹角，在两股气流能够彼此对冲的同时，还避免了彼此之间串风的情形(例如回风口201处的风进入回风管700中)。
本领域技术人员能够理解的是，两股气流对冲时，能够将两股气流打散，相对于使未经打散的气流直接吹向蒸发器而言，能够使蒸发器的各个部分都充分地接触流动的空气，提升了蒸发器500与空气的接触面积和使用效率。由于两个气流对冲时各自被打散，使得空气的流速也得到降低，延长了流动的空气与蒸发器500接触的时间，从而使得蒸发器500与空气之间的换热更加充分，进一步提升了蒸发器500的使用效率。而60°至85°的对冲夹角能够 使被打散的气流在流经蒸发器500时扩散得更加均匀。
至此，已经结合前文的多个实施例描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围并不仅限于这些具体实施例。在不偏离本发明技术原理的前提下，本领域技术人员可以对上述各个实施例中的技术方案进行拆分和组合，也可以对相关技术特征作出等同的更改或替换，凡在本发明的技术构思和/或技术原理之内所做的任何更改、等同替换、改进等都将落入本发明的保护范围之内。
