The main working process: the liquid refrigerant absorbs heat in the evaporator and vaporizes into a low-temperature and low-pressure gas, which is compressed The machine sucks in, compresses it into high-temperature and high-pressure gas, and then discharges it into the condenser, where it releases heat to the cooling medium (water or air), condenses into a high-pressure liquid, which is throttled by a throttle to a low-pressure and low-temperature refrigerant, and again It enters the evaporator to absorb heat and vaporize to achieve the purpose of circulating refrigeration. At present, the heat release process of the condenser is mainly that the high-temperature and high-pressure refrigerant flows through the heat exchange tube, and releases heat to the outside, that is, the cooling medium (water or air) through the fins of the heat exchange tube and the heat exchange tube in close contact.

The heat exchange efficiency of the current 7mm condenser needs to be improved under the premise of the same length and height.

Referring to FIG. 2, any fin 2 is provided with at least one row of perforations 3 corresponding to the number of rows of heat exchange tubes 1 through which the heat exchange tubes 1 pass. The fin 2 is uniformly divided into at least one basic unit corresponding to the number of rows of the heat exchange tubes 1 along the width direction. The width of any basic unit is greater than 18.2mm, and the center distance between two adjacent perforations 3 in any row of perforations 3 is less than 21mm.
任一翅片2上穿孔3的列数与换热管1的排数相同，即同一排的换热管1对应穿过一列穿孔3。任一翅片2上基本单元的个数同样与换热管1的排数相同。一个基本单元上设有一列穿孔3。每个基本单元的宽度相同。翅片2的宽度即翅片2在与换热管1的延伸方向垂直的方向上的尺寸。任一列穿孔3中相邻两个穿孔3之间的中心距即为相邻两个穿孔3的中心之间的距离，该距离即为同一排换热管1中相邻两跟换热管1之间的间距。本实施例提供的基本单元的宽度大于现有室外机冷凝器中翅片的宽度；本实施例提供的相邻两个穿孔的中心距小于现有室外机冷凝器中换热管的中心距。The number of rows of perforations 3 on any fin 2 is the same as the number of rows of heat exchange tubes 1, that is, the heat exchange tubes 1 in the same row pass through a row of perforations 3 correspondingly. The number of basic units on any fin 2 is also the same as the number of rows of heat exchange tubes 1. A row of perforations 3 is provided on a basic unit. The width of each basic unit is the same. The width of the fin 2 is the size of the fin 2 in the direction perpendicular to the extending direction of the heat exchange tube 1. The center distance between two adjacent perforations 3 in any row of perforations 3 is the distance between the centers of two adjacent perforations 3, which is the distance between two adjacent heat exchange tubes 1 in the same row of heat exchange tubes 1 The spacing between. The width of the basic unit provided in this embodiment is greater than the width of the fins in the existing outdoor unit condenser; the center distance of two adjacent perforations provided in this embodiment is smaller than the center distance of the heat exchange tubes in the existing outdoor unit condenser.
本实施例提供的一种冷凝器，提出在相同的室外机尺寸下，可通过优化翅片2的尺寸以及换热管1的间距来进一步地提高冷凝器的换热效果，进一步设计提出了一种新的翅片2尺寸和换热管1间距，本实施例的冷凝器相比现有换热管1管径相同的冷凝器，增加了翅片2宽度，减小了换热管1之间的间距，进而相同高度的冷凝器由于管距减小，管数就会增加，同时由于翅片2加宽换热面积进一步增加。进而在不改变空调室外机外壳的前提下，可以提升换热效率，提高能效。The condenser provided in this embodiment proposes that under the same outdoor unit size, the heat exchange effect of the condenser can be further improved by optimizing the size of the fins 2 and the spacing of the heat exchange tubes 1, and further design proposes a A new fin 2 size and heat exchange tube 1 spacing. Compared with the existing condenser with the same tube diameter of the heat exchange tube 1, the condenser of this embodiment has increased the width of the fin 2 and reduced the width of the heat exchange tube 1. The distance between the condenser and the condenser of the same height will increase due to the decrease of the tube distance. At the same time, the heat exchange area will be further increased due to the widening of the fin 2. Furthermore, without changing the casing of the outdoor unit of the air conditioner, the heat exchange efficiency and energy efficiency can be improved.
在上述实施例的基础上，进一步地，任一基本单元的宽度为21-22mm；任一列穿孔3中相邻两个穿孔3之间的中心距A为17-18mm。参考图2，可设置任一基本单元上的穿孔位于该基本单元的中间，从而任一基本单元 的宽度即为B，具体为21-22mm。On the basis of the foregoing embodiment, further, the width of any basic unit is 21-22 mm; the center distance A between two adjacent perforations 3 in any row of perforations 3 is 17-18 mm. Referring to Figure 2, the perforation on any basic unit can be set in the middle of the basic unit, so that the width of any basic unit is B, specifically 21-22mm.
进一步地，换热管1整体可呈L型。参考图3提供一种单排L型换热管101。参考图4提供一种双排L型换热管102。有利于提高换热管1的长度，增大换热面积，提高换热效果。每一排换热管1在高度方向上从上到下布置一排。换热管1整体也可呈直线状，可根据实际情况灵活设置，具体不做限定。参考图5提供一种单排直线型换热管103。Further, the heat exchange tube 1 may be L-shaped as a whole. Referring to FIG. 3, a single-row L-shaped heat exchange tube 101 is provided. Referring to FIG. 4, a double-row L-shaped heat exchange tube 102 is provided. It is beneficial to increase the length of the heat exchange tube 1, increase the heat exchange area, and improve the heat exchange effect. Each row of heat exchange tubes 1 is arranged in a row from top to bottom in the height direction. The heat exchange tube 1 can also be linear as a whole, and can be flexibly set according to actual conditions, and the details are not limited. Referring to FIG. 5, a single-row linear heat exchange tube 103 is provided.
在上述实施例的基础上，进一步地，穿孔3的直径为7.275-7.325mm。相邻两个翅片2之间的距离为1.2-1.4mm。即在换热管1呈L型时，L型的两个直线段的每个直线段上的翅片2均平行设置，且每个直线段上相邻两个翅片2之间的距离为1.2-1.4mm。在换热管1呈直线型时，换热管1上的翅片2平行设置，相邻两个翅片2之间的距离为1.2-1.4mm。该翅片2间距既可保证冷却介质(水或空气)顺利在翅片2间流动与翅片2充分接触，又可尽可能的提高翅片2面积，保证了换热效果。On the basis of the foregoing embodiment, further, the diameter of the perforation 3 is 7.275-7.325 mm. The distance between two adjacent fins 2 is 1.2-1.4 mm. That is, when the heat exchange tube 1 is L-shaped, the fins 2 on each of the two straight-line segments of the L-shape are arranged in parallel, and the distance between two adjacent fins 2 on each straight-line segment is 1.2-1.4mm. When the heat exchange tube 1 is linear, the fins 2 on the heat exchange tube 1 are arranged in parallel, and the distance between two adjacent fins 2 is 1.2-1.4 mm. The distance between the fins 2 can ensure that the cooling medium (water or air) flows smoothly between the fins 2 and fully contacts the fins 2, and can also increase the area of the fins 2 as much as possible to ensure the heat exchange effect.
在上述实施例的基础上，进一步地，相邻两列穿孔3交错设置。即对于相邻的两列穿孔3并不是平齐设置的，而是其中一列的穿孔3可对应于另一列穿孔3的间隙部位设置。相邻两列穿孔3对应相邻两排的换热管1。交错设置可利于换热，提高换热效率。On the basis of the above-mentioned embodiment, further, two adjacent rows of perforations 3 are arranged in a staggered manner. That is, the perforations 3 in two adjacent rows are not arranged flush, but the perforations 3 in one row can be arranged corresponding to the gaps of the perforations 3 in the other row. Two adjacent rows of perforations 3 correspond to two adjacent rows of heat exchange tubes 1. Staggered arrangement can facilitate heat exchange and improve heat exchange efficiency.
在上述实施例的基础上，进一步地，参考图6和图7，翅片2上位于底端的穿孔3的中心与翅片2底边之间的第一间距L1小于该穿孔3所在的一列穿孔3中位于顶端的穿孔3的中心与翅片2顶边之间的第二间距L2。On the basis of the above embodiment, and further, referring to Figures 6 and 7, the first distance L1 between the center of the perforation 3 at the bottom end of the fin 2 and the bottom edge of the fin 2 is smaller than the row of perforations where the perforation 3 is located. The second distance L2 between the center of the perforation 3 at the top end in 3 and the top edge of the fin 2.
具体的，参考图6，在翅片2上设有一列穿孔3时，该列穿孔3最低部的穿孔3的中心与翅片2底边之间的距离为第一间距L1，该列穿孔3最顶部的穿孔3的中心与翅片2顶边之间的距离为第二间距L2。参考图7，在翅片2上设有多列穿孔3时，多列穿孔3中位于最低部的穿孔3的中心与翅片2的底边之间的距离为第一间距L1，该位于最低部的穿孔3所在的一列穿孔3中位于顶部的穿孔3与翅片2的顶边之间的距离为第二间距L2。Specifically, referring to FIG. 6, when a row of perforations 3 is provided on the fin 2, the distance between the center of the perforation 3 at the lowest part of the row of perforations 3 and the bottom edge of the fin 2 is the first distance L1, and the row of perforations 3 The distance between the center of the topmost perforation 3 and the top edge of the fin 2 is the second distance L2. Referring to Figure 7, when multiple rows of perforations 3 are provided on the fin 2, the distance between the center of the perforation 3 at the lowest part of the multiple rows of perforations 3 and the bottom edge of the fin 2 is the first distance L1, which is located at the lowest The distance between the perforation 3 at the top and the top edge of the fin 2 in the row of perforations 3 where the perforations 3 of the part are located is the second distance L2.
设置第一间距小于第二间距，即设有距离翅片2的底边较近的换热管1，使得换热管1内部的介质可对冷凝器底端的部件进行换热，有利于避 免冷凝器底端的部件受外界环境的影响造成损坏。具体的，例如空调在制热工况下，室外环境温度较低，室外机的冷凝器底端容易结冰，设置换热管1距离底端较近可通过热传递改善该情况。The first distance is set to be smaller than the second distance, that is, the heat exchange tube 1 closer to the bottom of the fin 2 is provided, so that the medium inside the heat exchange tube 1 can exchange heat with the components at the bottom of the condenser, which is beneficial to avoid condensation The components at the bottom of the device are damaged due to the influence of the external environment.
