【具体实施方式】 【detailed description】
以下将结合附图所示的具体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。The invention will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, the embodiments are not intended to limit the invention, and the structural, method, or functional changes made by those skilled in the art in accordance with the embodiments are included in the scope of the present invention.
参图1至图3，介绍本发明冰箱用蒸发器的一具体实施方式，在本实施方式中，该冰箱用蒸发器100包括蒸发板10和制冷剂管20。Referring to Figs. 1 to 3, a specific embodiment of an evaporator for a refrigerator of the present invention will be described. In the present embodiment, the evaporator 100 for a refrigerator includes an evaporation plate 10 and a refrigerant pipe 20.
蒸发板10一般依照冰箱储藏室形状被设置为矩形板状，制冷剂管20与蒸发板10之间导热连接。冰箱200工作时，制冷剂管20中的制冷剂吸收储藏室S中的热量，与制冷剂管20导热连接的蒸发板10相当于增加了制冷剂管20与空气的接触面积，有益于提高制冷效率。The evaporation plate 10 is generally provided in a rectangular plate shape in accordance with the shape of the refrigerator storage compartment, and the refrigerant pipe 20 and the evaporation plate 10 are thermally connected. When the refrigerator 200 is in operation, the refrigerant in the refrigerant pipe 20 absorbs the heat in the storage chamber S, and the evaporation plate 10 thermally connected to the refrigerant pipe 20 is equivalent to increasing the contact area between the refrigerant pipe 20 and the air, which is beneficial to improve refrigeration. effectiveness.
蒸发板10上设置有用于安装制冷剂管20的凹槽11，优选地，凹槽11在蒸发板10上呈蛇形状弯折延伸，制冷剂管20至少部分地嵌入凹槽11内，这样可以增加制冷剂管20与蒸发板10的接触面积，提高制冷剂管20与蒸发板10之间的传热效率。凹槽11的截面呈可与制冷剂管20适配的弧形，以更加贴合制冷剂管20表面。The evaporation plate 10 is provided with a groove 11 for mounting the refrigerant tube 20. Preferably, the groove 11 is bent in a serpentine shape on the evaporation plate 10, and the refrigerant tube 20 is at least partially embedded in the groove 11, so that The contact area between the refrigerant tube 20 and the evaporation plate 10 is increased, and the heat transfer efficiency between the refrigerant tube 20 and the evaporation plate 10 is improved. The groove 11 has a cross section that is adapted to fit the refrigerant tube 20 to more closely conform to the surface of the refrigerant tube 20.
作为优选的实施方式，该蒸发板10与制冷剂管20之间配置有导热胶40，导热胶40可以固定蒸发板10与制冷剂管20之间的位置关系，并且，通过选用具有优良导热性质的导热胶40，可以优化蒸发板10与制冷剂管20间的热传递关系。As a preferred embodiment, a thermal conductive adhesive 40 is disposed between the evaporation plate 10 and the refrigerant tube 20. The thermal conductive adhesive 40 can fix the positional relationship between the evaporation plate 10 and the refrigerant tube 20, and has excellent thermal conductivity through selection. The thermal conductive adhesive 40 can optimize the heat transfer relationship between the evaporation plate 10 and the refrigerant tube 20.
在具体的加工过程中，凹槽11可以通过例如冲压的方式制得，此种加工方式工艺较为成熟，且成本较低。In a specific processing process, the groove 11 can be produced by, for example, stamping, and the processing method is relatively mature and low in cost.
蒸发板10上开设有与其一体的第一翅片311，如此，蒸发板10上形成由于开设第一翅片311而贯穿第一翅片311的第一通槽321。这样，冰箱储藏室S内的冷气可以穿过这些第一通槽321流动，加强了储藏室S内冷气的流动性。这样，可以避免冷气不流通造成的蒸发器100某处的冷量过于集中而造成的蒸发器100结霜。The evaporation plate 10 is provided with a first fin 311 integrally formed therewith. Thus, the first through groove 321 penetrating the first fin 311 by opening the first fin 311 is formed on the evaporation plate 10. Thus, the cold air in the refrigerator storage compartment S can flow through the first through grooves 321, which enhances the fluidity of the cold air in the storage compartment S. In this way, it is possible to prevent the evaporator 100 from frosting caused by excessive concentration of the cold portion of the evaporator 100 due to the cold air not flowing.
作为优选的实施方式，蒸发板10上还开设有与其一体的第二翅片312，第一翅片311和第二翅片312之间形成有贯穿蒸发板10的第二通槽322。In a preferred embodiment, the evaporation plate 10 is further provided with a second fin 312 integrally formed therewith, and a second through groove 322 penetrating the evaporation plate 10 is formed between the first fin 311 and the second fin 312.
第一翅片311和第二翅片312与蒸发板10间呈一夹角，且第一翅片311和第二翅片312平行排布。第一翅片311和第二翅片312与蒸发板10夹呈夹角的好处是：在不损失蒸发板10表面面积的同时，尽量地增加第一通槽321和第二通槽322的面积，如此可以保证蒸发器100的制冷效率不受影响。应当理解的是，这里所说的“第一”和“第二”并不代表结构或功能上的区别，而仅仅是为了描述的方便。The first fin 311 and the second fin 312 are at an angle with the evaporation plate 10, and the first fin 311 and the second fin 312 are arranged in parallel. The advantage that the first fin 311 and the second fin 312 are at an angle with the evaporation plate 10 is that the area of the first through groove 321 and the second through groove 322 is increased as much as possible without losing the surface area of the evaporation plate 10. This ensures that the cooling efficiency of the evaporator 100 is not affected. It should be understood that the terms "first" and "second" as used herein do not denote a structural or functional difference, but merely for convenience of description.
并且，虽然这里以蒸发板10上开设第一翅片311和第二翅片312为例对本发明的实施方式做阐述，但是，很显然的，在其它替换的实施方式中，本发明的蒸发板10上可以开设有更多个的翅片，在这些实施方式中，蒸发板10上的翅片实质上呈一“百叶窗”式的结构，此种实施方式仍应当视为不超脱本发明的精神范畴。Moreover, although the embodiment of the present invention is described herein by taking the first fin 311 and the second fin 312 on the evaporation plate 10 as an example, it is obvious that in other alternative embodiments, the evaporation plate of the present invention More fins can be opened on the 10th. In these embodiments, the fins on the evaporation plate 10 are substantially in the form of a "louver" type, and such an embodiment should still be regarded as not exceeding the spirit of the present invention. category.
为了配合制冷剂管20在蒸发板10上的配置形状，在本实施方式中，可以设置若干并列排布的翅片组30，这样，既不用更改传统的制冷剂管20的排布方式，又可以实现第一通槽321和第二通槽322在蒸发板10上的最大面积的分布，保证蒸发板10良好的抗结霜功能。In order to match the arrangement shape of the refrigerant tube 20 on the evaporation plate 10, in the present embodiment, a plurality of fin groups 30 arranged side by side may be provided, so that the arrangement of the conventional refrigerant tubes 20 is not changed, and The distribution of the maximum area of the first through groove 321 and the second through groove 322 on the evaporation plate 10 can be achieved to ensure a good anti-frosting function of the evaporation plate 10.
蒸发板10和制冷剂管20都优选地采用铝质材料制成，以获取优异的导热性和机械加工性能。Both the evaporation plate 10 and the refrigerant tube 20 are preferably made of an aluminum material to obtain excellent thermal conductivity and machinability.
配合参照图4，采用本发明冰箱用蒸发器100的冰箱200，由于蒸发板10与制冷剂管20间的换热效率更高，所以具有更低的耗电量，并且，通过在蒸发板10上开设与其一体的翅片31，使得蒸发板上形成贯穿蒸发板10的第一通槽321，可以在保证蒸发器100制冷效率的同时，使冰箱储藏室内的冷气更易流动，避免蒸发器100结霜，降低冰箱的除霜频次。Referring to FIG. 4, the refrigerator 200 using the evaporator 100 for a refrigerator of the present invention has lower power consumption due to higher heat exchange efficiency between the evaporation plate 10 and the refrigerant pipe 20, and passes through the evaporation plate 10 The fin 31 integrated with the upper plate is formed such that the first through groove 321 penetrating the evaporation plate 10 is formed on the evaporation plate, so that the cooling efficiency of the evaporator 100 can be ensured, and the cold air in the refrigerator storage chamber can be more easily flowed, thereby avoiding the evaporator 100 knot. Frost, reduce the frequency of defrosting in the refrigerator.
