具体实施方式
以下将结合附图所示的各实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。例如，如果将图中的设备翻转，则被描述为位于其他单元或特征“下方”或“之下”的单元将位于其他单元或特征“上方”。因此，示例性术语“下方”可以囊括上方和下方这两种方位。设备可以以其他方式被定向(旋转90度或其他朝向)，并相应地解释本文使用的与空间相关的描述语。在本发明中，在卧式风冷制冷柜正常使用时，朝向地面的方向为向下，背离地面的方向为朝上，平行于地面的方向为水平方向。
本发明实施例提供了一种卧式风冷制冷柜，如图1-图3所示，所述卧式风冷制冷柜包括存储间室1和用于向所述存储间室1提供冷气的风冷制冷系统；在所述存储间室1的相对的两侧壁的顶部设置有侧部出风道2，所述侧部出风道2连通所述风冷制冷系统的风道，且能够向所述存储间室1提供冷气；这里，风冷制冷系统通常包括：风道、冷凝器、压缩机、风机3、风冷蒸发器4、干燥过滤器和毛细管等；在图1-图3中，在存储间室1中的端部的底部设置有连通风道的回风道5，在风道中设置有风冷蒸发器4和风机3；在制冷时，风机3转动且风冷蒸发器4制冷，从而冷空气从侧部出风道2吹入存储间室1中，较暖的空气从回风道5回流到风道，在经过风冷蒸发器4的周围时，较暖的空气被冷却为冷空气，之后冷空气沿着侧部出风道2吹到存储间室1中。
如图1所示，其中：所述侧部出风道2设置有能够吹出斜向下方向的冷风的出风口21；在所述存储间室的底部设置有直冷式蒸发器6。这里，侧部出风道2所吹出的斜向下方向的冷风，该冷风通常会吹到若干储藏物的顶部，由于冷风的密度较大且冷风的方向为斜向下，因此，冷风会沿着若干储藏物的间隙向下流动，从而使得每个储藏物能够均匀变冷。综上所述，该侧部出风道2的设计能够让存储间室1中的若干储藏物均匀受冷。
这里，侧部出风道2和端部出风道7所吹出的冷风会沿着至上而下的方向流动，在流动的过程中，该冷风会逐渐变暖，进而不利于底侧的储藏物的冷藏，因此，可以在底部中设置直冷式蒸发器6，从而为底侧的储藏物提供冷量。可以理解的是，直冷式制冷容易导致在存储间室1的壁上产生冰霜，但是由于该存储间室1还具有风冷制冷，因此，该冷气能够带走一部分水汽，从而 极大的减少了存储间室1的壁上产生冰霜的可能性。
如图1所示，侧部出风道2可以为一个水平设置的通风管道，在其侧面设置有出风口21；这里，出风口21的数量可以为四个。
这里，如图1所示，所述直冷式蒸发器6设置于所述存储间室1的底壁；如图6所示，所述直冷式蒸发器6设置于所述存储间室1的侧壁；如图7所示，在底壁和侧壁中均设置有直冷式蒸发器6。可以理解的是，通常存储间室1为长方体形状，因此，底壁通常只有一个，而侧壁通常有四个，因此，可以只有一个侧壁中设置有直冷式蒸发器6，也可以两个、三个或四个侧壁中设置有直冷式蒸发器6。
优选的，所述侧部出风道2嵌在所述卧式风冷制冷柜的柜体中。
优选的，如图1-3所示，所述存储间室1一端部设置有上下布置的端部出风道7和回风道5。可以理解的是，通常存储间室1呈长方体形状，则在该存储间室1的相对的两个侧面的顶部均设置有侧部出风道2，此外，在另外两个相对的侧面中的任一即可以为端部。并且端部出风道7会连接到风冷制冷系统，从而端部出风道7能够向存储间室7吹入冷气。
这里，在存储间室1的顶部会有三股冷风，即相对的两侧壁的侧部出风道2、以及端部出风道7所吹出的三股冷风，因此，很容易在存储间室1的内部形成涡旋气流，涡旋气流能够保证存储间室1纵截面保持冷量分布均匀，从而整体上使得存储间室1内的温度保持均匀以提高制冷效果。这里，在该卧式风冷冷柜中可以设置有压机舱8，在压机舱8中安装有压缩机，集水盒等设备，如图1所示，回风道5可以安装在压机舱8的外表面，且该外表面即为存储间室1的一个侧面。
优选的，如图2所示，所述回风道5设置有若干个回风道51，所述若干回风道51的尺寸由中间向两侧逐渐变大。这里，若干回风道51由中间向两侧逐渐变大，从而可以保证内胆表面较大的风循环量，降低内胆处温度高的风险，提高箱内温度均匀性。
可选的，所述风冷制冷系统中的风机3为离心式风机。在离心式风机的工作中，气流由风机轴向进入叶片空间，然后在叶轮的驱动下一方面随叶轮旋转；另一方面在惯性的作用下提高能量，沿半径方向离开叶轮，靠产生的离心力来做功，因此，可以产生较大的静压及送风距离。
优选的，如图8所述，在所述存储间室的底壁上侧设置有盖板9，所述盖板9与底壁的距离大于零，且所述盖板上设置有若干回风道51，所述盖板9与底壁之间的通道、以及所述若干回风道51构成回风道，在所述盖板9的下方盘绕直冷蒸发器6。这里，直冷蒸发器6可以为各种类型，例如，管壁式、丝管式或吹胀式等。这里，盖板9设置在底壁的上侧，并且与下面的距离大于零，从而在盖板9和底壁之间会有通道，且盖板上设置有若干回风道51，可以理解的是， 该通道需要与风冷制冷系统的风道相连，从而在风冷制冷系统工作时，风冷制冷系统能够从盖板上的若干回风道51中吸入较暖的空气。
优选的，如图9所示，所述存储间室的底壁中盘绕直冷蒸发器6。
优选的，在所述侧部出风道2和端部出风道7均设置有能够打开或关闭风道的风帘组件8；这里可以根据具体的要求来设定风帘组件8的位置，例如，为每个出风口21都设置有一个风帘组件8，从而可以对每个出风口21进行精确控制；也可以为整个侧部风道2设置一个风帘组件8，从而该风帘组件8可以打开或关闭整个侧部出风道2。与此类似，在端部出风道7上也可以设置有多个出风口，则可以为每个出风口都设置一个风帘组件8，也可以为整个端部出风道7设置一个风帘组件8。
如图4-5所示，所述风帘组件8包括框架81和风帘82，所述框架81中形成风口811，所述风帘82的上部设置有转轴821，所述转轴821可转动的安装在所述框架81中，所述风帘82用于遮挡所述风口811。这里，在该风冷制冷系统工作时，风机3会转动，冷风经过风帘组件8，吹动风帘82，从而风帘82沿着其转动轴821转动，打开风口811，从而冷气可以流过风口811、并进入到存储间室1；而在对风冷蒸发器4除冰时，风机3会停止转动，从而在风帘82的自身重力的作用下，风帘82就可以遮挡风口811，因此，除冰时所产生的热气不会进入到存储间室1中，从而可以防止存储间室1中的温度的升高。可以理解的是，风帘82的形状与风口811的形状相配合。例如，在图4中，风帘82和风口811的形状都为矩形。
优选的，如图5所示，所述框架81设置有卡槽812，所述转动轴821可转动的安装到所述卡槽812中。在图5中，在框架81中，设置有用于容纳转动轴821的卡槽812，卡槽812的直径大于转动轴821，从而转动轴821可以相对于卡槽812转动；为了便于将转动轴821安装进卡槽812中，卡槽812可以具有一个开口813，从而沿着该开口813可以将转动轴821给卡进卡槽812中。
本发明实施例二提供了用于上述卧式风冷制冷柜的风冷制冷系统，如图10所示，该方案为旁通循环+热融霜方案，分为两部分：(1)制冷循环，制冷剂经过压缩机11压缩后，高温高压气体进入冷凝器12进行冷凝，经过冷凝器12制冷变为高压液体，进入毛细管13节流变为低温低压的两相制冷剂(即气体和液体共存的制冷剂状态)，进入电磁阀14控制制冷剂分配，一路先经过直冷蒸发器16后进入风冷蒸发器3，一路直接进入风冷蒸发器3，制冷剂经过风冷蒸发器3后回到压缩机11，完成循环；(2)化霜循环，化霜控制阀15打开，由于止回阀17的作用，压缩机11排出的高温高压制冷剂气体直接进入风冷蒸发器3，进行化霜，化霜完成后制冷剂回到压缩机11。
本发明实施例三提供了用于上述卧式风冷制冷柜的风冷制冷系统，如图11所示，为串联循环+电加热除霜方案，分为两部分：(1)制冷循环，制冷剂经过压缩机11压缩后，高温高压气体进入冷凝器12进行冷凝，经过冷凝器12制冷变为高压液体，进入毛细管13节流变为低温低压的两相制冷剂(即气体和液体共存的制冷剂状态)，制冷剂依次进入直冷蒸发器16和风冷蒸发器3进行制冷后返回压缩机11。
本发明实施例四提供了用于上述卧式风冷制冷柜的风冷制冷系统，如图12所示，为单循环+热融霜方案，分为两部分：(1)制冷循环，制冷剂经过压缩机11压缩后，高温高压气体进入冷凝器12进行冷凝，经过冷凝器12制冷变为高压液体，进入毛细管13节流变为低温低压的两相制冷剂(即气体和液体共存的制冷剂状态)，经过电磁阀14，进入风冷蒸发器3，制冷剂经过风冷蒸发器3后回到压缩机11，完成循环；(2)化霜循环，化霜控制阀15打开，压缩机排出的高温高压制冷剂气体直接进入风冷蒸发器3，进行化霜，化霜完成后制冷剂回到压缩机11。
