在本公开的一些实施例中，如图4所示，由于沿上部送风道142内空气的流动方向风力越来越弱，为了使多个上部送风道142的出口的送风量基本一致，送风均匀，上部送风道142的出口的出风面积沿上部送风道142内空气的流动方向逐渐增大。在本公开的一些实施例中，由于沿下部回风道122内为回风，其风力由风速的吸力产生，沿空气的流动方向风力越来越弱，为了使多个下部回风道122的出口的回风量基本一致，送风均匀，下部回风道122的出口的回风面积沿下部回风道122内空气的流动方向逐渐减小。在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。In some embodiments of the present disclosure, as shown in FIG. 4, since the wind is weaker in the flow direction of the air in the upper air supply duct 142, the air supply amount of the outlets of the plurality of upper air supply ducts 142 is substantially the same. The air supply is uniform, and the air outlet area of the outlet of the upper air supply duct 142 gradually increases along the flow direction of the air in the upper air supply duct 142. In some embodiments of the present disclosure, since the wind is returned along the lower return air passage 122, the wind force is generated by the suction of the wind speed, and the wind force becomes weaker and weaker along the flow direction of the air, in order to make the plurality of lower return air passages 122 The return air volume of the outlet is substantially the same, the air supply is uniform, and the return air area of the outlet of the lower return air passage 122 gradually decreases along the flow direction of the air in the lower return air passage 122. In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
本公开的实施例中虽然以卧式风冷冷柜为例进行说明，但应当理解，本公开的应用并不限于此。Although the horizontal air-cooling refrigerator is taken as an example in the embodiment of the present disclosure, it should be understood that the application of the present disclosure is not limited thereto.
以上仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求所述的保护范围为准The above is only the specific embodiment of the present disclosure, but the scope of the present disclosure is not limited thereto, and any change or replacement that can be easily conceived within the technical scope of the present disclosure should be covered by any person skilled in the art. It is within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure shall be subject to the scope of protection stated in the claims.
