Description

翅片管式换热器用传热管和使用了其的翅片管式换热器 Fin tube type heat transfer tubes and the heat exchanger uses thereof fin tube heat exchanger

技术领域 FIELD

[0001] 本发明涉及翅片管式换热器用传热管和使用了其的翅片管式换热器,特别是涉及适合用于家庭用空调、箱型空调等空调机中的翅片管式换热器的传热管和使用了该传热管的翅片管式换热器。 [0001] The present invention relates to a fin-tube type heat transfer tubes and the heat exchanger using fin-tube heat exchanger thereof, and more particularly relates to finned tubes suitable for household air conditioner, air conditioner air conditioning box of and heat transfer tubes using fin-tube heat exchanger of the heat transfer pipe of the heat exchanger.

背景技术 Background technique

[0002] 一直以来,除了家庭用空调、汽车用空调、箱型空调等空调用设备以外,在冰箱、热泵式热水器等中也使用作为蒸发器或冷凝器进行工作的换热器,其中,在家庭用室内空调、营业用箱型空调中,最通常使用在传热管上组装翅片而成的结构的翅片管式换热器。 [0002] All along, in addition to household air conditioners, automobile air conditioner outside, box-type air conditioners and other air-conditioning equipment, in the refrigerator, heat pump water heaters and other heat exchangers are also used to work as an evaporator or condenser, which, in room air conditioners for home use, air conditioners for business use box, the most commonly used in the heat transfer tube is assembled from the fin tube heat exchanger fin structure.

[0003] 另外,近年来,出于保护臭氧层、防止地球变暖等的观点考虑,也正在进行取代以往的氟利昂系制冷剂而利用了变暖系数较低的自然制冷剂的换热器的开发,其中,使用了以二氧化碳为主体的制冷剂的热水器受到关注,其开发正在推进,但是在这种换热器中也使用了与上述相同的翅片管式换热器。 [0003] Further, in recent years, for the protection of the ozone layer, prevention of global warming viewpoint, also under conventional substituted fluorocarbon refrigerant heat development using a lower natural refrigerant warming coefficient wherein, using carbon dioxide as a refrigerant heater attention, their development is advancing, but in this heat exchanger it is also the same as described above using fin-tube heat exchanger.

[0004] 可是,该翅片管式换热器通常实际应用于使用被实施了预定加工的翅片(外表面翅片)与传热管、并以密接该翅片与传热管的方式组装而成的结构的换热器。 [0004] However, the finned tube heat exchanger applied actually typically implemented using a predetermined processing of the fin (the outer surface of the fin) and the heat transfer tubes, and is in close contact with the finned heat transfer tubes are assembled a heat exchanger having a structure. 而且,在形成为这种结构的换热器中,通过使制冷剂在传热管内流通,另一方面,使作为换热流体的空气沿着翅片向与传热管成直角的方向流动,从而在制冷剂与空气之间进行换热。 Further, the heat exchanger is formed in such a structure, the refrigerant flows through the heat transfer tube, on the other hand, the air serving as heat exchange fluid flows into the heat transfer tube along the direction perpendicular to the fin, thereby performing heat exchange between the refrigerant and the air.

[0005] 而且,作为在这种翅片管式换热器中使用的传热管之一,公知有具有利用多个分隔壁将扁平形状的管内部分割为多个流路而成的结构的扁平多孔管。 [0005] Further, as one of the heat transfer tubes used in such a fin-tube type heat exchanger is known having an inner tube with a plurality of flat-shaped partition wall is divided into a plurality of flow paths having a structure flat porous tube. 另外,在该扁平多孔管中,通常使用通过分流组合挤压(日文一卜* 一&押出)铝或铝合金而获得的扁平多孔管,但是作为这种扁平多孔管的截面形状,例如如日本特开平6 — 142755号公报(专利文献I)明确所示,一般常使用将管内部的流路形成为四边形状的扁平多孔管。 Further, in the flat porous tube, typically using a flat porous tube by porthole extruding (a Japanese extrusion BU * & a) obtained by aluminum or aluminum alloy, but such a flat cross-sectional shape of the porous tube, for example, Japanese Japanese Patent 6 - FIG No. 142755 (Patent Document I) clear, generally often used inside the manifold flow passage is formed as a flat rectangular shape porous tube. 另外,在这种扁平多孔管中,增加流路的表面积的做法对提高换热效率是有效的,因此在日本特开平5 — 222480号公报(专利文献2)中,明确了在形成为四边形状的孔的内表面上形成许多微小的凹凸而增加表面积的方法。 Further, in such a porous flat tube, the practice of increasing the surface area of ​​the flow channel is effective to improve heat transfer efficiency, and therefore Japanese Unexamined Patent 5 - Publication No. 222,480 (Patent Document 2), a clear square shape is formed the method of increasing the surface area of ​​many tiny irregularities formed on the inner surface of the bore. 通过如此增大流路的表面积,从而增大在孔的内部流通的制冷剂与孔表面之间的接触面积,通过提高制冷剂侧的导热率、即提高制冷剂与传热管之间的导热率,从而实现了换热效率的提闻。 By thus increasing the surface area of ​​the flow passage, thereby increasing the contact area between the inside bore of the circulating refrigerant with the bore surface, by improving the thermal conductivity of the refrigerant side, i.e., to improve thermal heat transfer between the refrigerant and the tube rate, in order to achieve the heat transfer efficiency to mention the smell.

[0006] 但是,在利用分流组合挤压铝或铝合金等的挤压成形来形成扁平多孔管的情况下,由于无法使形成于孔的内表面的凹凸的大小过小,因此无法充分地增大表面积。 In the case [0006] However, the use of porthole extruding aluminum or aluminum alloy extrusion molding to form a flat perforated tube, can not be formed due to the unevenness of the inner surface of the hole size is too small, can not be sufficiently increased large surface area. 特别是在出于使换热器小型化等的目的而减小了扁平多孔管的情况下,所形成的孔也变小,因此基于由这种凹凸的形成使表面积增加从而提高导热率的效果不能说是足够的。 In particular, the purpose of making the size of the heat exchanger is reduced like a case where the flat tube is perforated, the holes formed becomes smaller, thus increasing effect on the thermal conductivity thereby improving the unevenness formed by such a surface area It can not be said enough.

[0007] 另外,在上述专利文献I (日本特开平6 — 142755号公报)的图9的(C)、日本特开平9 一72680号公报(专利文献3)中,明确了将扁平多孔管的孔截面形状形成为三角形形状的内容。 [0007] Further, in the above-described Patent Document I - FIG. (Japanese Patent Laid-Open the 6th 142 755 JP) of (C), Japanese Patent Laid-Open 9 the 1st 72680 Publication 9 (Patent Document 3), the clear flat perforated tube content hole sectional shape of a triangular shape. 但是,在专利文献I中,在进行多孔管的挤压成形时,只不过将延长多孔管挤压用模具的寿命、提高产品的尺寸、精度作为目的,在此,作为使用这种多孔管挤压用的模具制作的多孔管的孔形状的一例,只是单列举了三角形形状。 However, in the Patent Document I, the porous tube during extrusion molding, but the extension of the porous tube extrusion die life, improve product size, accuracy as a destination, in this case, the use of such a porous tube extrusion one case with the hole shape of the pressure molding of the porous tube, a triangular shape include only a single. 另外,在专利文献3中,涉及一种多孔扁平管,其通过冷轧或冷挤压获得预定的厚度与平坦的表面,并且通过加工固化来改善抗拉强度,能够赋予适当的硬度与弹性,并明确了使孔形状形成等腰三角形的结构作为能够获得这种特性的多孔扁平管的结构。 Further, Patent Document 3 relates to a porous flat tube, which is obtained with a predetermined thickness by cold rolling a flat surface or cold extrusion, and to improve the tensile strength by work hardening, it is possible to impart an appropriate hardness and elasticity, and clearly the structure of the pores formed in the shape of an isosceles triangle can be obtained as a porous structure characteristic of such flat tubes.

[0008] 但是,在这些专利文献1、3所明确的扁平多孔管中,只是单纯将通过挤压加工而形成的多孔管的孔形状形成了三角形形状,或者只不过是为了改进多孔管的硬度、弹性而将其孔形状形成了等腰三角形形状。 [0008] However, the hole shape of the perforated pipe 3 in these patent documents are expressly flat porous tube will simply formed by extrusion forming a triangular shape, or simply to improve the hardness of the porous tube , elasticity, pore shape to a shape of an isosceles triangle. 即,在此,对于三角形的具体的形状、传热管的导热率没有任何研究。 That is, in this case, none of the studies for the particular triangular shape, thermal conductivity of the heat transfer tube.

具体实施方式 Detailed ways

[0033] 以下,为了更具体地明确本发明,参照附图详细地说明本发明的实施方式。 [0033] Here, in order to clearly present invention more specifically, embodiments of the present invention in detail with reference to the drawings.

[0034] 首先,在图1中,以立体图的方式概略示出了使用了基于本发明的翅片管式换热器用传热管的翅片管式换热器的实施方式之一。 [0034] First, in FIG. 1, schematically in perspective shows an embodiment based on the use of one fin-tube heat exchanger of the fin tube according to the present invention, the heat exchanger tubes. 在此,换热器10通过两根扁平多孔管14、14以插入被设置于相互平行且隔开恒定距离配置的多张翅片12的狭缝状的组装孔16内、并密接于孔内表面的方式固定于该翅片12上而构成。 Here, the heat exchanger 14, 14 to 10 are inserted through the two-hole flat tubes disposed in parallel to and spaced from the slit-shaped hole 16 the assembly 12 a plurality of fins arranged at a constant distance, and within the pores close contact is fixed to the surface of the fin 12 is configured.

[0035] 更详细地说,翅片12与以往相同地利用由铝或铝合金构成的金属板材形成,也如图2所示,形成为呈平坦的矩形的平面形状的薄壁的板状翅片。 [0035] In more detail, the fins 12 with the use of the same conventional sheet metal made of aluminum or an aluminum alloy, also shown in Figure 2, is formed as a thin-walled flat rectangular planar shape of a plate fin sheet. 另外,在该翅片12上形成有用于组装扁平多孔管14的组装孔16作为从矩形形状的翅片12的一端向翅片12的宽度方向(在图2中,为左右方向)延伸了预定长度的预定宽度的狭缝。 Further, assembly holes are formed with a flat perforated tube assembly 14 for a 16 in the width direction of the fins 12 (in FIG. 2, left and right direction) extending from one end of the rectangular fins 12 on the predetermined fin 12 the slit width of a predetermined length. 而且,在该组装孔16周围,与翅片12—体地形成有预定高度的卡圈部18,该卡圈部18呈U字形状。 Further, around the installation hole 16, the collar portion 18 is formed with a predetermined height 12- fin member, the collar portion 18 has a U-shape.

[0036] 另一方面,众所周知,扁平多孔管14是利用由铝或铝合金等构成的金属材料形成的、在此独立形成有沿管轴方向延伸的10个孔20而成的、呈扁平形状的多孔管。 [0036] On the other hand, it is known the use of flat porous tube 14 is formed of a metal material such as aluminum or an aluminum alloy, this separate aperture 10 formed in the tube axis direction 20 is formed by extending, flat shape the porous tube. 在此,孔20也如将与管轴垂直的方向上的截面的一部分放大后的图3所示,呈三角截面形状,并且在此形成为其3边的长度全部相同的正三角形形状。 Here, as also the view of a partial cross section in a direction perpendicular to the axis of the tube 3 an enlarged hole 20, a triangular cross-sectional shape, and in this form for the same length of all three sides of the equilateral triangle shape. 而且,如图所示,形成为这种形状的孔20的、相邻的孔20彼此分别在上下方向反转的形态下、换言之在转动180°而交替配置的形态下沿扁平多孔管14的宽度方向隔开预定间隔地相互平行排列。 Further, as shown, is formed into such a shape of the aperture, adjacent holes 20 in the vertical direction are inverted form, in other words 20 each other along the porous tube 14 at the flat form and are arranged alternately rotated 180 ° of widthwise spaced apart a predetermined interval arranged in parallel to each other.

[0037] 另外,在这种孔20中,构成为通过4倍的其截面积除以孔的边的长度之和而定义水力直径D与孔的高度(多孔管的厚度方向上的高度)h之比(D/h)处于0.40〜0.80的范围内。 [0037] Further, in such holes 20, constituting the height (height in the thickness direction of the porous tube) h through 4 times its cross-sectional area divided by the length of the edge of the hole and a defined hydraulic diameter D of the hole the ratio (D / h) is in the range of 0.40~0.80. 即,在此,由于孔20为正三角形形状,因此D/h = 0.6660.67,构成为处于上述范围内。 That is, in this case, since the hole 20 is an equilateral triangle shape, D / h = 0.6660.67, configured to be in the aforementioned range.

[0038] 这样,通过以水力直径D与孔的高度h之比成为上述范围内的值的方式设定孔20的形状,从而使制冷剂有效地通过该孔20的角度较小的部分,接触每单位体积的制冷剂的孔内表面的面积增加,有利于制冷剂与传热管之间的导热率的提高。 [0038] Thus, by the ratio of the height h of the hole hydraulic diameter D becomes a value within the above range way the shape of the hole 20 is set so that the refrigerant efficiently through a smaller angle of the aperture portion 20, the contact the volume of pores per unit surface area of ​​the refrigerant, is advantageous to increase the thermal conductivity between the refrigerant and the heat transfer tubes. 另外,制冷剂通过这种角度较小的部分,从而产生局部的流动状态,因此也能够更有效地提高导热率。 Further, the refrigerant through such an angle smaller portions, so that a local flow condition, and therefore it is possible to more effectively improve the thermal conductivity. 另外,在该D/h的值小于0.40的情况下,孔20变得过小,制造变困难,因此并不实用。 Further, in a case where the value of D / h is less than 0.40, the hole 20 becomes too small, it becomes difficult to manufacture, and therefore not practical. 另一方面,在D/h的值大于0.80的情况下,接触每单位体积的制冷剂的接触面积的增加变得不充分,难以发挥导热率的提高效果。 Increasing the other hand, in a case where the value of D / h greater than 0.80, the contact of the refrigerant per unit volume of the contact area is insufficient, it is difficult to exert the effect of improving the thermal conductivity.

[0039] 而且,使用这种扁平多孔管14与翅片12,将多张该翅片12在与分别形成的组装孔16对齐的状态下以相互平行且隔开恒定距离的方式进行配置,向该对齐后的组装孔16内嵌入扁平多孔管14,通过以扁平多孔管14直接或间接密接于组装孔16内表面的方式进行组装,从而构成目标翅片管式换热器10。 [0039] Moreover, with this flat porous tube 14 and fins 12, the fins 12 will be a plurality of mutually parallel manner and spaced at a constant distance and assembly alignment holes 16 are formed in a state arranged to after the assembly holes 16 aligned with the insert hole flat tubes 14, assembled by adhesion directly or indirectly the inner surface of the installation hole 16 of the embodiment of the flat porous tube 14, thereby constituting the target finned tube heat exchanger 10. 另外,众所周知,该扁平多孔管14与翅片12之间的组装利用基于压入或密接嵌合的组装、借助于钎焊的接合或者借助于粘接剂的粘着等公知的各种方法来进行,作为一体的翅片管式换热器而完成。 Further, it is known, the flat press-on or press-fitting assembly, joined by means of brazing or by means of a known adhesive such as an adhesive by various methods using a porous tube 14 and the assembly between the fins 12 to , as an integral fin-tube heat exchanger is completed. 另外,作为构成这种翅片管式换热器的传热管的扁平多孔管14的各自的两端部分别连接于在此未图示的集管,扁平多孔管14的10个孔20、即沿管轴方向延伸的供制冷剂流通的10条流路分别汇聚于制冷剂的入口侧与出口侧,形成为翅片管式换热器10。 Further, the flat tubes constituting such a porous heat transfer fin-tube heat exchanger tubes of each of both end portions 14 are respectively connected to the manifold, not shown here, multi-hole flat tubes 20 of the 10 holes 14, i.e. for the refrigerant in the tube axis direction of the flow passage 10 respectively converge at the refrigerant inlet side and the outlet side, is formed as a fin tube heat exchanger 10.

[0040] 因而,在形成为这种基于本发明的结构的翅片管式换热器10中,形成于扁平多孔管14的孔20的形状形成为不仅单纯增大了制冷剂与孔内表面之间的接触面积、而且也能够增大接触每单位体积的制冷剂的接触面积、并有利地提高制冷剂侧的导热率的三角形形状,因此在扁平多孔管14中,在管内流通的制冷剂与传热管之间的换热效率有效地提高,其结果,能够有利地提高换热器10的换热性能。 [0040] Accordingly, this is based on the formed structure of the present invention in a fin tube heat exchanger 10, is formed in the flat shape of the hole 14 of the perforated pipe 20 is formed not only simply increases the refrigerant and the surface of the bore area of ​​contact between, and also possible to increase the contact area per unit volume of the refrigerant, and advantageously improving the thermal conductivity of the triangular shape on the refrigerant side, and therefore in the flat perforated pipe 14, flowing in the refrigerant tube heat exchange efficiency between the heat transfer tubes effectively improved, as a result, can advantageously improve the performance of the heat exchanger 10. 另外,通过使用发挥如此高的导热率的扁平多孔管14,能够使换热器10小型、轻量化,并且也有利地发挥了制造成本削减这样的效果O Further, by using such a play-hole flat tubes 14 of high thermal conductivity, the heat exchanger 10 can be made small, lightweight, and advantageously also exhibit a reduction in the manufacturing cost of such an effect O

[0041] 以上,详细说明了本发明的代表性的实施方式之一,但是这终归不过是例示,应理解为,本发明丝毫不由这样的实施方式的具体记述限定性地解释。 [0041] The above detailed description of one embodiment of a representative embodiment of the present invention, but which after all are merely examples, it should be understood that the present invention does not by the detailed description of such embodiments be construed as restrictive.

[0043] 另外,形成于扁平多孔管14的孔20的形状在上述实施方式中形成了正三角形形状,但是只要是水力直径D与孔的高度h之比(D/h)处于预定的范围内的三角形形状,就可以适当地选择直角三角形、等腰三角形等各种三角形形状。 [0043] Further, formed in the shape of the hole 20 of the flat porous tube 14 is formed in the shape of an equilateral triangle embodiment described above, but as long as the ratio of the height h of the hole hydraulic diameter D (D / h) is within a predetermined range the triangular shape may be appropriately selected various triangular shape of a right triangle, isosceles triangle and the like. 而且,关于连结三角形形状的3个顶点的边,也除了像例示的正三角形形状那样呈直线状连结顶点以外,只要是D/h满足上述关系,就也能够设为具有预定的曲率半径的圆弧状的边。 Further, on three sides of the triangular shape connecting the vertices, as also illustrated in addition to the regular triangle shape as a shape other than a straight line connecting the apexes, as long as the D / h satisfies the above relationship, it can be set to a circle having a predetermined radius of curvature arc-shaped edges.

[0044] 此外,该孔20的内表面在此设为平坦的面,但是也可以是形成有微小的凹凸(槽、突条)的面。 [0044] Further, the inner surface of the bore 20 is a flat surface in this set, but may also be formed with fine irregularities (groove, ridge) plane. 通过形成这种凹凸,能够进一步增大每单位体积的制冷剂与孔20的表面之间的接触面积,能够更有效地提高制冷剂与传热管之间的导热率。 By forming such irregularities, it is possible to further increase the contact area between the surface of the refrigerant per unit volume of the bore 20, can be more effectively increase the thermal conductivity between the refrigerant and the heat transfer tubes.
