散热组件和制冷装置
本申请要求于2017年2月15日提交中国专利局、申请号为201710080370.4、发明名称为“散热组件和制冷装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及制冷技术领域，具体而言，涉及一种散热组件和制冷装置。
背景技术
如今冰箱的体积越来越大，对能耗的要求越来越高，在有限空间的压缩机仓里不仅有压缩机，而且还有冷凝器等发热设备，通过风扇对压缩机仓进行通风和散热。在如此紧凑的空间，通过合理的流道设计降低流动阻力，增强散热效果是提升冰箱整体性能在关键因素。
而目前，压缩机仓的主要设备主要有压缩机，冷凝器，冷凝器风扇，一般而言，所用的冷凝器为管翅式。压缩机是整个制冷系统的能量来源，将低温低压的制冷剂在旋转机械的作用下压缩成高温高压的过热气体，在这个过程中产生大量热量。高温高压的制冷剂过热气体从压缩机出口排出，进入到冷凝器中，通过冷凝风扇与周围空气进行强制空气对流换热。可见，在有限容积的狭小空间内，压缩机和冷凝器的高效换热将直接影响整个冰箱系统的制冷能力。同时，压缩机和冷凝风扇都是旋转机械，在工作过程将产生噪声，其中压缩机主要产生振动噪声，冷凝风扇主要产生气动噪声。压缩机和冷凝风扇的噪声水平将直接影响整机的噪声性能。
受限于空间布局，现有的冰箱产品都存在着散热能力不足和噪声水平较高的问题：
缺点1：压缩机散热存在问题，由于受到空间布局和空气流场的影响，在压缩机的被风面由于流速降低，被空气携带的热量减少，不能有效散热。
缺点2：冷凝器散热存在问题，由于受到空间布局的限制，以及冷凝器自身结构原因，造成空气流经冷凝器时，受到的空气阻力较大，流速降低，散热性能变差。
缺点3：压缩机由于通过旋转结构将制冷剂从低温低压状态压缩到高温高压，产生振动噪声，是冰箱噪声的主要来源，严重影响冰箱噪声性能。
缺点4：由于一部分空气经由冷凝器下部的空间流过，导致流量损失。
