[0025] 如图1所示,蛇形散热片系统10包括具有第一模具14和第二模具16的辊轧成型模具12,该辊轧成型模具12被配置成使片料18成型。 [0025] As shown, the serpentine fins having a roller system 10 includes a first die 14 and second die 16 of mold roll 12, the roll forming die 12 is configured so that sheet material 18 formed. 产生的成型片料20包括一系列压痕(indentation) 22。 Forming sheet material 20 comprises a series of indentations produced (indentation) 22. 压痕22的顺序被配置成利于将成型片料20挤压成适合用作热交换部件的散热片单元24。 Sequential indentation 22 is configured to facilitate extruded into shaped flakes 20 suitable for use as fin unit 24 of the heat exchange member. 在这方面,压机26被配置成接纳或拖入成型片料20并使前进的成型片料20变慢或停止,并且将蛇形挤压成紧密的队列。 In this regard, the press 26 is configured to receive a sheet material or molded drag molded piece 20 and feed forward slow down or stop 20 and pressed into tight serpentine queue. 在一实施例中,成型片料20包括由于通过成型模具12而被成型的扇形皱褶或褶裥(pleat)。 In one embodiment, since the molded sheet material 20 comprises a mold 12 by being molded or pleated scallops (pleat). 如图1所示,这些扇形皱褶在片料18的交替的侧面上被成型。 1, the scallops are formed on alternating sides of the sheet material 18. 这一系列的扇形褶皱预先处置这些成型片料,以折叠成散热片单元24。 This series of fan folds predisposed these flakes forming, folded into a fin unit 24. 压机26完成使成型片料20在峰部和谷部处弯曲,以产生蛇形散热片单元24。 26 to complete the molding press sheet material 20 is bent at the peaks and valleys, to produce a serpentine fin unit 24. 正如本文中所描述的,散热片单元24可以是蛇形的,并且包括配置成传送流体通过的蜂窝状通道。 As described herein, the fin unit 24 may be serpentine, and includes a passage configured to transfer fluid through a honeycomb.

[0026] 片料18可以包括任何的适用材料。 [0026] The sheet material 18 may comprise any suitable material. 适用材料的示例通常包括金属和聚合物。 Examples of suitable materials include metals and polymers generally. 更具体地,适用材料包括具有良好的热传导特性和抗腐蚀性的可锻的金属。 More specifically, suitable material includes a metal having good heat transfer characteristics and corrosion resistance of the malleable. 适用材料的具体示例可以取决于特定的热交换应用,然而,不锈钢、铝和铝合金、铜和铜合金等是适用材料的具体示例。 Specific examples of suitable material may depend on the particular heat exchange application, however, stainless steel, aluminum and aluminum alloys, copper and copper alloys and the like are specific examples of suitable materials. 一些实施例的好处是:片料18可以相对比用在传统的热交换设备中的片料更薄。 Some advantage of this embodiment is that: the relative ratio of flake 18 can be used in conventional heat exchange apparatus thinner flakes. 这至少部分地是因为打裙或蛇形处理工艺(serpentining process)使散热片单元24能够成型为单件或单一件,而不是成型为一堆相对易碎的单独板材。 This is due at least in part play a skirt or serpentine Process (serpentining process) so that the fin unit 24 can be molded as a single piece or a single piece, instead of forming into a stack of individual sheets relatively fragile. 更薄的片料能够使热传递更快且效率更高。 Thinner flakes can be made faster and more efficient heat transfer. 此外,更薄的片料能够使成型的蜂窝状通路更小,这通过增加表面也改善了热传递的效率,并且使得热传递系数更高。 Further, flakes can be made thinner passage forming honeycomb less, which is also improved by increasing the surface of heat transfer efficiency, and such that higher heat transfer coefficients.

[0027] 图2为图1的蛇形散热片系统10的侧视图。 [0027] FIG. 2 is a serpentine fin a side view of system 10 of FIG. 1. 图1的蛇形散热片系统10与图1的蛇形散热片系统10相似,因此,为了简洁起见,参照图1所描述的这些项目将不再被描述。 10 is similar to serpentine fin system 10 of FIG. 1 FIG serpentine fin system 1, therefore, for the sake of brevity, those items described with reference to FIG. 1 will not be described. 如图2所示,成型片料20包括一系列褶痕(creaSe)30和嵌板(panel) 32,所述嵌板32利于形成褶裥。 2, the sheet material 20 comprises a series of shaped crease (creaSe) 30 and a panel (Panel) 32, a panel 32 facilitate the formation of gathers. 通过调节褶痕30之间的距离,可以调节散热片单元24的厚度。 By adjusting the distance between the crease 30, you can adjust the thickness of the fin unit 24. 例如,通过增大相应褶痕30之间的距离,可以增加散热片单元24的厚度。 For example, by increasing the distance between the respective crease 30, you can increase the thickness of the fin unit 24. 相反地,例如,通过减小各个褶痕30之间的距离,可以减小散热片单元24的厚度。 In contrast, for example, by reducing the distance between the respective crease 30, you can reduce the thickness of the fin unit 24. 以这种方式,散热片单元24的厚度可以被调节成适于特殊的热交换任务。 In this manner, the thickness of the fin unit 24 may be adjusted to suit a particular heat exchange tasks.
