Description
技术领域 technical field
本发明涉及的是一种制冷技术领域的设备，特别是一种用于制冷空调装置中的管束带式换热器。The invention relates to equipment in the technical field of refrigeration, in particular to a tube-bundle heat exchanger used in refrigeration and air-conditioning devices.
背景技术 Background technique
翅片管式换热器是目前制冷空调装置中用得最多的换热器型式，房间空调器和风冷式冷水机组大都采用这种换热器。这种换热器在加工时，是在翅片上冲孔、翻边，翻边的高度即为翅片间的间距，一般大于1毫米，翻边形成的圆环套在管子上，使得翅片得以通过这个圆环与管子有良好的接触，提高传热效率。目前这种换热器采用的换热管的直径大多在4毫米或者更大，其中又以7毫米以上占据主导地位，造成换热器体积较大。如果要减小体积，就需要采用更细的管子。但当管径进一步减小时，就不能在翅片上冲出能够足以翻边的材料来。因此翅片管式换热器难以小型化。Finned tube heat exchanger is currently the most widely used heat exchanger type in refrigeration and air-conditioning equipment, and most room air conditioners and air-cooled chillers use this type of heat exchanger. When processing this kind of heat exchanger, the fins are punched and flanged. The height of the flanging is the distance between the fins, which is generally greater than 1 mm. The ring formed by the flanging is placed on the tube so that the fins It is possible to have a good contact with the tube through this ring and improve the heat transfer efficiency. At present, the diameter of the heat exchange tubes used in this kind of heat exchanger is mostly 4 mm or larger, and the diameter of more than 7 mm occupies a dominant position, resulting in a large heat exchanger. If you want to reduce the volume, you need to use thinner tubes. But when the pipe diameter is further reduced, it is not possible to punch out enough material on the fins to flang. Therefore, it is difficult to miniaturize the finned tube heat exchanger.
经对现有技术的文件检索发现，管带式换热器是一种结构型式紧凑的换热器，如中国专利申请号为200410017004.7，专利名称为“管带式房间空调蒸发器”，这种换热器是在带状材料中冲出孔来流制冷剂，孔径可以做到1毫米以内，因此在同样的换热能力要求下换热器的体积远小于翅片管式紧凑。这种类型的换热器在汽车空调上得到了广泛的应用。但是这种材料的换热器中的小孔是靠挤压产生的，目前只能用于铝作为材料的换热器。而在一些高腐蚀性的场合，需要采用铜等高抗腐蚀性材料，但是铜却不能用类似的工艺制造成这种换热管带。After searching the documents of the prior art, it is found that the tube-belt heat exchanger is a heat exchanger with a compact structure. The heat exchanger punches out holes in the strip material to flow the refrigerant, and the diameter of the holes can be within 1 mm. Therefore, under the same heat transfer capacity requirements, the volume of the heat exchanger is much smaller than that of the finned tube type. This type of heat exchanger is widely used in automotive air conditioners. However, the small holes in the heat exchanger of this material are produced by extrusion, which can only be used for heat exchangers made of aluminum at present. In some highly corrosive occasions, high corrosion-resistant materials such as copper need to be used, but copper cannot be manufactured into this heat exchange tube belt by a similar process.
发明内容 Contents of the invention
本发明的目的在于针对现有技术的不足，提供一种管束带式换热器，使其紧凑性大大好于翅片管式换热器，接近于管带式换热器，同时又不受管带式换热器材料必须是铝的限制。The object of the present invention is to address the deficiencies in the prior art and provide a tube-bundle heat exchanger whose compactness is much better than that of the fin-tube heat exchanger, close to the tube-belt heat exchanger, and at the same time free from Tube and belt heat exchanger material must be limited to aluminum.
本发明是通过以下技术方案实现的，本发明包括管束带、翅片和带孔套片，管束带由一根或者数根细直径圆管并排组成，管束带的两端伸入带孔套片中，管束带弯成蛇形，在蛇形管带之间放入翅片，翅片通过焊接与管束带固定。The present invention is achieved through the following technical solutions. The present invention includes a tube band, fins and a perforated sleeve. The tube band is composed of one or several small-diameter round tubes arranged side by side, and the two ends of the tube band extend into the perforated sleeve. In the process, the tube band is bent into a serpentine shape, and fins are placed between the serpentine tube bands, and the fins are fixed with the tube band by welding.
所述带孔套片中有多个并排的小孔，这些小孔的数量等于组成管束带的圆管的数量，小孔的大小正好允许细直径圆管穿入，带孔套片起到将多个细直径圆管固定位置的作用。There are a plurality of side-by-side small holes in the perforated sleeve, the number of these small holes is equal to the number of round tubes forming the tube belt, the size of the small holes just allows the thin diameter round tube to penetrate, and the perforated sleeve plays the role of The role of multiple thin diameter circular tubes in fixed positions.
所述管束带的圆管，直径在0.2毫米到5毫米之间。The diameter of the round tube of the tube bundle is between 0.2mm and 5mm.
本发明的换热器在应用时，需要进行热交换的二组流体，一组流过组成管束带的细直径圆管内，另一组流过管束带外表面以及翅片的表面。细管内的流体，通过细直径圆管的壁面以及管束带之间的翅片，与流过管束带外表面以及翅片表面的另一组流体进行热交换。翅片起到了增加传热面积的作用。When the heat exchanger of the present invention is applied, two groups of fluids for heat exchange are required, one group flows through the thin-diameter circular tubes forming the tube bundle, and the other group flows through the outer surface of the tube bundle and the surface of the fins. The fluid in the narrow tube exchanges heat with another group of fluid flowing through the outer surface of the tube band and the surface of the fins through the wall surface of the thin diameter circular tube and the fins between the tube bands. The fins serve to increase the heat transfer area.
本发明与已有的翅片管式换热器比较，可以用较细的圆管代替较粗的圆管。翅片管式换热器的直径一般在4毫米以上，而本发明的圆管直径可以达到1毫米以下，在同样的圆管换热面积下，圆管的体积可以减少至原来的四分之一以下，使得整个换热器体积减少一半以上。Compared with the existing finned tube heat exchanger, the present invention can replace thicker round tubes with thinner round tubes. The diameter of the finned tube heat exchanger is generally more than 4 mm, while the diameter of the round tube of the present invention can reach less than 1 mm. Under the same heat exchange area of the round tube, the volume of the round tube can be reduced to a quarter of the original Below one, the volume of the entire heat exchanger is reduced by more than half.
本发明与已有的管带式换热器比较，材料选取上摆脱了必须是铝的限制，对于不适合于使用铝材的腐蚀性高的场合，则可以选用铜、铜合金等抗腐蚀性的金属材料，从而可以较管带式换热器有更广泛的应用场合。Compared with the existing tube-and-belt heat exchanger, the present invention can get rid of the restriction that aluminum must be used in material selection, and for occasions with high corrosion resistance that is not suitable for using aluminum, copper, copper alloys, etc. can be selected for corrosion resistance. Metal materials, so that it can be used in a wider range of applications than tube-and-belt heat exchangers.
