Description

利用分布式合成喷流致动器进行热管理的系统和方法 Using a distributed synthetic jet actuator and method for thermal management systems

技术领域 FIELD

本发明一般涉及热管理技术,尤其涉及利用分布式喷流致动器来冷却发热体或元件的系统和方法。 The present invention relates generally to thermal management techniques, in particular, it relates to systems and methods for use of distributed jet actuator or cool the heat generating element.

背景技术 Background technique

冷却发热体是许多不同技术领域中所关注的问题。 Cooling the heating element is a problem in many different technical fields of interest. 尤其是在微处理器中,伴有收缩热预算(thermal budget)的散热等级的升高造成了对于超越传统热管理技术的新冷却办法的需求。 Elevated levels of the heat, especially in the microprocessor, with the contraction thermal budget (thermal budget) created a need for new approaches to go beyond the traditional cooling thermal management techniques. 此外,对于用在小型手持设备,比如便携式数字助理(PDA's)、移动电话、便携式CD播放器以及类似的消费产品中的有效热管理策略的需求大大地增加。 In addition, for use in small handheld devices, such as portable digital assistants (PDA's), mobile phones, portable CD players, and effective demand thermal management strategy similar consumer products greatly increased. 确实,热管理是单芯片和多芯片模块中目前达到最新技术发展水平的集成电路的设计及封装技术的主要挑战。 Indeed, thermal management is a major challenge for single-chip and multi-chip modules currently the-art development of integrated circuit design and packaging technology.

传统上,冷却大型微电子设备的需求已经通过使用强制对流空气冷却技术而得到满足。 Traditionally, large-scale cooling microelectronic devices demand has been met and the forced convection air cooling by using a technique. 在有或没有散热器的情况下都能执行强制对流。 With or without heat-sink can be done by forced convection. 并且传统上采用风扇来提供全面冷却或局部冷却。 And to provide full or partial cooling using cooling fans conventionally.

风扇能够提供充裕的体积流速,但风扇的使用有几个明显的缺点。 Fan can provide ample volume flow rate, using a fan but has several significant drawbacks. 对于以给定的体积流速除热来说,风扇的效率较低。 For a given volumetric flow rate of heat removal, the low efficiency of the fan. 此外,使用风扇来全面或局部冷却热环境常常会导致以磁为基础的风扇马达产生电磁干扰和噪音。 In addition, the use of cooling fans to full or partial thermal environment often results in magnetically based fan motor noise and electromagnetic interference. 使用风扇还需要相对大量的运动部分,以便能够冷却热体或微电子元件。 The use of fans also require relatively large amounts of moving parts, to be able to heat or cool a microelectronic element. 由此或由于其他原因,风扇在长期可靠性方面可能有局限。 Thus, or for other reasons, the fan in the long-term reliability may have limitations.

移动电器引入了空间限制这一额外的复杂化因素,这可能会难以利用风扇来实现预期效果,同时热管理需求增大导致必须使用更大的风扇驱动更高的流速。 Portable electric space constraints introduced this additional complicating factor, it may be difficult to use the fan to achieve the desired effect, while increasing thermal management requirements necessitate using a larger fan drive higher flow rates. 由于在某些情况下功率耗散需求导致必须把风扇直接置于散热器之上,所以流动结构交互作用所引起的相关噪音等级已经成为了额外的关注点。 Because in some cases resulting in power dissipation requirements must be placed directly on top of the radiator fan, so the related noise caused by the flow structure interaction has become an additional level of concern.

在一些情况下,如在类似便携式数字助理(“PDAs”)、蜂窝电话等手持设备中,对于热管理的需求已经通过采用使产生的热通过热散布器分散到手持设备外壳的策略来得到满足。 In some cases, as in the similar portable digital assistants ( "PDAs"), cellular phones and other handheld devices, demand for thermal management has been through the use of heat generated by the heat spreader dispersed policy handheld device housing to be met . 因此,所生成的热通过设备的外壳或表面经过自然对流而散失了。 Accordingly, the heat generated by the surface of the device housing or dissipated through the natural convection.

尽管这些方法很普遍,但它们具有某些缺陷,这些缺陷将随着产生更多热量的新产品的开发而加剧。 Although these methods are common, but they have some drawbacks that will generate more heat with the development of new products and intensified. 采用热散布策略的困难只是在于它经常不能有效除去足够的热量。 Difficulties thermal spread strategy only in that it is often not effectively remove sufficient heat. 此外,所散失的热量会导致手持设备壳体温度升高,这从消费者使用人机工程学的观点来看是不理想的。 In addition, the loss of heat can cause the handheld device case temperature rise, which use ergonomic from a consumer point of view is not ideal.

在努力改善现有冷却技术的一些限制的过程中,已经研究在热管理中使用合成或“零净质量流量(zero-net-mass-flux)”喷流致动器。 In an effort to improve some of the limitations of the prior art cooling has been studied using synthetic or "zero net mass flow rate (zero-net-mass-flux)" jet actuator thermal management. 例如,美国专利No.6123145讨论了使用合成喷流致动器来进行冷却。 For example, U.S. Patent No.6123145 discusses the use of synthetic jet actuator to cool. 因此,将美国专利No.6123145作为参考全部合并进来,就像完全在此陈述一样。 Therefore, the US Patent No.6123145 come in all incorporated by reference as if fully set forth herein as. 与传统喷流不同,合成喷流致动器不需要向系统增加质量,因此提供了一种有效指引气流横过热表面的紧凑方式。 Different from the conventional jet, synthetic jet actuator without increasing the mass of the system, thereby providing a compact manner effective flow cross guide surface overheating. 由于喷射流完全从外围流体中产生,因此它们能够便利地形成整体而不需要复杂的管件。 Since the jet produced from the full periphery of the fluid, and therefore they can conveniently be formed integrally without the need for a complicated pipe.

作为使用合成喷流致动器的热管理技术开发的另一个例子,Glezer和Mahalingam开发出了用于通路冷却的装置和方法。 As another example of a synthetic jet actuator thermal management technology development, Glezer Mahalingam, and developed an apparatus and method for cooling passages. 该装置和方法在美国专利No.6588497中有所说明,因此将其作为参考全部合并进来,就像完全在此陈述一样。 The apparatus and methods are described in U.S. Patent No.6588497, so as to come fully incorporated by reference, as if fully set forth herein.

尽管前述美国专利中所述的技术解决了行业中的一些限制,但仍然存在对于改善前述技术的、不断增长的需求。 Although the foregoing United States patent technology to solve some of the limitations of the industry, but there is still improvement to the aforementioned technology, the growing demand. 例如,需要更有效、更充分或更紧凑的合成喷流致动器。 For example, more effective, more compact and more or fully synthetic jet actuator. 理想的是,获得更紧凑的冷却装置。 Ideally, a more compact cooling apparatus. 另一方面,也需要使冷却流分布到热环境的远处部分。 On the other hand, it is necessary to cool the stream to a remote portion of the heat distribution environment.

因此,本行业中存在迄今为止尚未满足的、希望解决前述不足的需求。 Therefore, there is so far the industry has not been met, hope to solve the aforementioned lack of demand.

具体实施方式 Detailed ways

I.合成喷流致动器A.典型的合成喷流致动器的基本设计图1A表示合成喷流致动器10的一个例子,包括确定和包围了内室14的外壳11。 I. Synthesis jet basic design of the actuator A. typical synthetic jet actuator 1A shows an example of the actuator 10 Synthesis jet, comprising determining and enclosing an internal chamber 14 of the housing 11. 外壳11和内室14实质上可以采取任何几何构形,但为了便于讨论和理解,以横截面形式表示在图1A中的外壳11具有硬的侧壁12、硬的前壁13、和后隔膜18,该后隔膜能够变形到一定程度以允许膈膜18相对于内室14向内和向外运动。 11 and the inner housing chamber 14 can take virtually any geometric configuration, but for ease of discussion and understanding, represented in cross section in FIG. 1A housing 11 having a sidewall 12 of a hard, rigid front wall 13, and the diaphragm 18, after the diaphragm can be deformed to a certain extent to allow the diaphragm 18 inwardly and outwardly with respect to the movement 14 inside the chamber. 前壁13具有可以是任何形状的孔口16。 The front wall 13 has an aperture 16 may be of any shape. 孔口与后隔膜18完全相对,并使内室14连接到具有外围流体39的外部环境。 After the diaphragm aperture 18 and opposed, and the inner chamber 14 is connected to an external environment having ambient fluid 39.

可通过任何适当的控制系统24来控制柔性隔膜18运动。 24 can control the movement of the flexible membrane 18 by any suitable control system. 例如,隔膜18可设有金属层,金属电极可邻近金属层,但与金属层分开设置,以便隔膜18能通过施加在电极与金属层之间的电偏压而被驱动产生移动。 For example, the separator 18 may be provided with a metal layer, a metal layer adjacent to the metal electrode may be, but is provided separately from the metal layer, so that the diaphragm 18 by an electrical bias is applied between the electrode and the metal layer is driven to produce movement. 此外,能通过任何适当的装置控制电偏压的产生,例如但不限于计算机、逻辑处理器或信号发生器。 Further, by any suitable electrical bias generation control means, such as, but not limited to, a computer, logic processor, or signal generator. 控制系统24能使得隔膜18周期性地运动或调整成时间谐波运动,并迫使流体流入和流出孔口16。 Control system 24 enables the diaphragm 18 to move periodically, or adjusted to the time harmonic motion, and force fluid into and out orifice 16.

现在将参考图1B和1C说明示例的合成喷流致动器10的工作。 Reference will now be working 1B and 1C illustrate exemplary synthetic jet actuator 10. 图1B表示当隔膜18受控如箭头26所示地向室14内部运动时的合成喷流致动器10。 1B shows the membrane 18 when controlled as indicated by arrow 14 to the interior of the synthesis chamber when moving jet actuator 26 as shown in 10. 室14的容积减小而流体通过孔口16喷射出来。 It decreases the volume of the fluid chamber 14 is ejected through the orifice 16. 当流体通过孔口16流出室14时,流体流在锐利的孔口边缘30处分开并形成涡流层32,该涡流层卷成漩涡34并开始在由箭头36指示的方向上移离孔口边缘30。 When the fluid chamber 16 flows through the orifice 14, the fluid flow sharp edge of the opening 30 to dispose the opening 32 and forms a fluidized bed, the fluidized bed 34 and rolled into the vortex starts moving in the direction indicated by arrow 36 from the edge of the opening 30.

图1C表示当隔膜18受控如箭头38所示地相对于室14向外运动时的合成喷流致动器10。 1C shows the diaphragm 18 when controlled as indicated by arrow 38 with respect to the synthesis chamber 14 upon outward movement of the jet actuator 10. 室14的容积增大且外围流体39涌入室14中,如箭头组40所示。 Volume chamber 14 increases and the peripheral fluid influx chamber 39 14, as shown by arrow 40 group. 隔膜18由控制系统24控制,从而当隔膜18离开室14时,漩涡34已经离开了孔口边缘30,从而不会受到引入室14内的外围流体39的影响。 Diaphragm 18 is controlled by a control system 24, such that when the membrane 18 leaves the chamber 14, swirl edge 34 has left the orifice 30, so as not to be affected by the ambient fluid 14 is introduced into the chamber 39. 与此同时,漩涡34强烈地卷吸从远离于孔口16之处引来的外围流体,从而合成了外围流体39的喷射流。 At the same time, a strong vortex entrainment 34 from the fluid away from the periphery of the aperture 16 is attracted to synthesize the periphery of the fluid jet 39.

B.具有混合压电致动器的合成喷流致动器如上所述,第一实施例的合成喷流致动器10的隔膜18包括电致动器,所述电致动器由以特定激发频率驱动的金属电极和金属层组成。 B. mixing a synthetic jet actuator is a piezoelectric actuator as described above, the first embodiment of the synthetic jet actuator 10 includes a diaphragm 18 electric actuator, the electric actuator is controlled by a particular excitation frequency of the metal electrode and the metal layer of the drive components. 该电激励使得合成喷流致动器10的隔膜18振动,从而改变合成喷流致动器10的室14的内部容积。 The electrical stimulus such synthetic jet actuator 18 vibration of the diaphragm 10, thereby changing the internal volume of the synthetic jet actuator 10 of chamber 14.

可选地,如图2所示,合成喷流致动器40可以包括确定了室45的外壳47。 Alternatively, as shown in Figure 2, the synthetic jet actuator 40 may include a housing defining the chamber 45 is 47. 该室的容积可通过使柔性隔膜42以时间谐波运动方式移动而被改变,该运动是由压电致动器41激励隔膜42而引起的。 The volume of the chamber may be varied by the flexible diaphragm 42 moves in a time harmonic motion, the motion is a piezoelectric actuator 41 of the diaphragm 42 caused by the excitation. 图2是具有外壳47的合成喷流致动器40的切开侧视图,该外壳由比较刚硬的圆顶壁43、比较刚硬的圆筒形侧壁44以及形成了致动器40的底壁的柔性隔膜42确定。 Figure 2 is a cut side view of the housing 47 of synthetic jet actuator 40 of the housing by a rigid dome wall 43 Comparative Comparative rigid cylindrical side wall 44 and the actuator 40 is formed of the bottom wall of the flexible membrane 42 is determined. 如图所示,侧壁使顶壁43连接到隔膜42。 As shown, the side walls so that the top wall 43 is connected to the diaphragm 42. 优选地,侧壁44和顶壁43由单件硬材料制成,比如塑料等。 Preferably, the side wall 44 and top wall 43 is made of a single piece of hard material, such as plastic or the like. 当然,也可以由金属材料或其他具有适当硬材料来构造壁43,44。 Of course, it may have a suitably hard material or of a metallic material other walls 43, 44 be constructed. 此外,形成合成喷流致动器40的材料不必是刚性的。 In addition, the material forming the synthetic jet actuator 40 need not be rigid. 材料可以具有一些柔性。 Materials may have some flexibility. 本领域普通技术人员基于特定的实施方式将很容易找出适于合成喷流致动器40的恰当材料。 Those of ordinary skill in the art will readily identify appropriate material suitable synthetic jet actuator 40 based on specific embodiments.

如上所述,顶壁43、柔性隔膜42和侧壁44形成了合成喷流致动器40的外壳47并确定了具有容积的室45。 As described above, the top wall 43, side walls 44 and flexible membrane 42 form a synthetic jet actuator housing 40 and 47 determines a chamber 45 having a volume. 本实施例40的外壳47具有圆筒形。 Example 40 of the present embodiment of the housing 47 has a cylindrical shape. 该种构形不是必需的,且所选择的特定构形是为了使人理解这一点:即合成喷流致动器40可以采取几乎任何整体形状。 This kind of configuration is not required, and the particular configuration chosen is to make understanding this: the synthetic jet actuator 40 may take virtually any overall shape.

在合成喷流致动器40的本实施例中,孔口46形成在侧壁44的一部分中。 In the synthetic jet actuator 40 of the present embodiment, an aperture 46 is formed in a portion of the sidewall 44. 孔口46可射流地连接室45和外围流体48。 The aperture 46 may be fluidically connected to the fluid chamber 45 and the periphery 48. 孔口46的具体大小和形状对于本实施例40并不重要。 In particular size and shape of the aperture 46 of the embodiment 40 is not critical to the present embodiment. 作为举例,孔口46可以是圆形开口或者是侧壁44中的水平或垂直槽。 By way of example, the aperture 46 may be circular openings in the side wall 44 or vertical or horizontal slots.

图3是合成喷流致动器40的第二实施例的平面图,更确切地表示了压电致动器41和柔性隔膜42。 FIG 3 is a plan synthetic jet actuator 40 of the second embodiment, and more particularly shows a flexible diaphragm 41 and 42 of the piezoelectric actuator. 换句话说,图3能想象成从下侧或致动器40的“底部”看合成喷流致动器40。 In other words, FIG. 3 from the lower side can be thought of as the actuator or the "bottom" 40 viewed synthetic jet actuator 40. 如可从图中看到的那样,隔膜42连接在侧壁44上。 As can be seen from the figure, the separator 42 is connected to the side wall 44. 优选地,隔膜42通过适合于用来构造隔膜42和侧壁44的材料的粘合剂而被连接到侧壁44上。 Preferably, the diaphragm 42 by a suitable adhesive to the material for the side wall 44 of the diaphragm 42 and the structure is connected to the side walls 44. 可选地,隔膜42可通过其他连接机构或设备连接到侧壁44上。 Alternatively, the diaphragm 42 may be connected to the side wall 44 through other connecting mechanism or device. 连接方法对于本实施例40不重要。 For the method of Example 40 is connected is not important to the present embodiment. 不过,优选的是所选择的连接方法能使侧壁44与隔膜42之间密封。 However, it is preferable that the selected connection method enables a seal between the side wall 44 and the diaphragm 42.

隔膜42优选地由弹性体或聚合物材料构成。 The diaphragm 42 is preferably formed of an elastomeric or polymeric material. 在本实施例中弹性体或聚合物隔膜42不是必需的;不过,由这些材料构成的隔膜是优选的。 Examples elastomer or polymer membrane 42 is not necessary in the present embodiment; however, a separator made of these materials are preferred. 传统上,压电致动器由与压电片连接的金属隔膜构成。 Conventionally, a piezoelectric actuator is constituted by a metal plate connected to the piezoelectric diaphragm. 不过,在某些实施方式中有利的是,利用聚合(类似塑料)或弹性(类似橡胶)材料构成压电致动器的隔膜。 However, in certain advantageous embodiments, the use of polymeric (plastic-like) or elastomer (rubber-like) piezoelectric material diaphragm actuator. 可选地,聚合或弹性隔膜可与金属隔膜结合起来使用以形成混合隔膜。 Alternatively, the polymerization elastic membrane or diaphragm may be bonded to the metal used to form mixed together diaphragm.

弹性体或聚合物可由许多特定材料构成,比如聚异戊二烯、聚异丁烯、聚丁二烯和/或聚氨酯。 Or elastomeric polymers may be numerous specific material, such as polyisoprene, polyisobutylene, polybutadiene and / or polyurethane. 对于本实施例40,由于弹性体或聚合物材料具有被拉伸后仍能弹回到其初始形状而不发生永久变形的能力,所以选择它来构造隔膜42。 For Example 40 of the present embodiment, since the elastomeric or polymeric material having a still spring back after being stretched to its original shape without permanent deformation occurs, so that the diaphragm 42 is configured to select it.

这种修改的致动器结构至少有两个优点。 Such modifications of the actuator structure has at least two advantages. 第一,使用弹性体或聚合物隔膜一般能降低致动器的自然共振频率,使得其更优地以低频(例如,<200Hz)使用。 First, an elastomer or polymer membrane is generally lower the natural resonant frequency of the actuator, so that it is more preferably to a low frequency (e.g., <200Hz) used. 这使得致动器的工作声音比较小。 This allows the actuator operation noise is relatively small. 第二,与趋向于在压电材料以及通常用来把压电材料贴到金属上的粘合剂中产生更大应力的金属隔膜相比,这种结构一般具有优良的可靠性。 Second, compared with the piezoelectric material tends to the metal diaphragm and the piezoelectric material is typically attached to the adhesive on the metal to greater stress, which structure generally has an excellent reliability.

如上所述,压电致动器41连接到弹性体或聚合物隔膜42上。 As described above, the piezoelectric actuator 41 is connected to the elastomer or polymer membrane 42. 压电致动器41优选地通过合适的粘合剂安装到隔膜42上。 Piezo-electric actuator 41 is preferably mounted to the diaphragm 42 by a suitable adhesive. 压电致动器41由电导线49提供电能。 The piezoelectric actuator 41 powered by electrical leads 49. 电导线49不仅向压电致动器41提供电能,还控制致动器41的工作。 Only electrical leads 49 to the piezoelectric actuator 41 to provide power, also controls the operation of the actuator 41. 确切地说,导线49把压电致动器与电源及控制系统50连接起来,该控制系统优选地与合成喷流致动器40的外壳47分离。 Specifically, the wire 49 of the piezoelectric actuator 50 and power and control system are connected, the control system preferably with the synthetic jet actuator 47 separating the housing 40. 当然,在某些实施例中,电源及控制系统50可以安装在合成喷流致动器40的外壳47上,或者甚至可以安装在外壳47内。 Of course, in some embodiments, power supply and control system 50 may be mounted on the housing synthetic jet actuator 40 to 47, or even 47 may be mounted within the housing.

电源及控制系统使压电致动器41振动。 Power and control system 41 so that actuation of the piezoelectric vibrating actuator. 压电致动器41的振动使得隔膜42以时间谐波运动的形式振动。 The piezoelectric actuator 41 causes the vibration of the vibrating membrane 42 as a time harmonic motion. 压电致动器41优选地以隔膜42的谐振频率振动。 Piezo-electric actuator 41 is preferably be a resonant frequency of vibration of the diaphragm 42. 当然,可以通过使压电致动器以不同频率工作而控制隔膜的振动幅度和频率。 Of course, it is possible to control the amplitude and frequency of vibration of the diaphragm by the piezoelectric actuators operate at different frequencies. 本领域普通技术人员将很容易调整压电致动器41的振动,以便产生所希望的隔膜42的振动频率和幅度。 Those of ordinary skill in the art will readily adjust the vibration of the piezoelectric actuator 41, the vibration frequency and amplitude in order to produce the desired diaphragm 42.

如上有关第一实施例10所述,第二实施例40中的隔膜42的振动导致在致动器40的孔口46处形成流体的合成喷射流52。 As a first embodiment, the vibration of about 10, a second embodiment of the separator 42 of Example 40 leads to the synthesis of the fluid is formed at the aperture 40 of the actuator 46 jet 52. 当隔膜42相对于室45向内运动时,室45的容积减小而流体通过孔口46射出。 When the diaphragm 42 to move inwardly with respect to the chamber 45, the volume of the fluid chamber 45 is reduced and is emitted through the aperture 46. 当流体通过孔口46从室45内射出时,在孔口边缘处分流并形成涡流层,涡流层卷成漩涡并离开孔口46。 When the fluid passes through the orifice 46 is emitted from the inner chamber 45, and the disposition is formed in the edge of the orifice flow fluidized bed, the fluidized bed volume and exit apertures 46 into the vortex. 这些漩涡卷吸外围流体48并利用该流体形成合成喷射流52。 These vortices entrained ambient fluid 48 is formed using the synthetic jet stream of fluid 52.

类似于第一示例的合成喷流致动器10的工作,当隔膜42相对于室45向外运动时,室45的容积增大。 Similar to the first working example of the synthetic jet actuator 10 of the diaphragm 42 relative to the outward movement of chamber 45, when the volume of chamber 45 increases. 容积的增大导致在孔口46处形成压力梯度,从而外围流体48涌入室45中。 The increase in volume results in a pressure gradient at the aperture 46, so that the influx of ambient fluid 48 in the chamber 45. 然后,当隔膜42振回室45内时,室45中的流体被排出,形成如上所述的合成喷射流52。 Then, when the diaphragm chamber 42 back to the transducer 45, the fluid chamber 45 is discharged, is formed of a synthetic jet stream 52 as described above.

III.分布式冷却装置A.第一例:单致动器装置如上所述的合成喷流致动器10、40可以用在许多不同的实施例中。 . III distributed cooling apparatus A. First Example: Synthesis of a single actuator device described above jet actuators 10, 40 may be used in many different embodiments. 不过,合成喷流致动器10、40的一个特殊修改对于被称为是分布式冷却应用是优选的。 However, the synthetic jet actuator 10, 40 for a special modification is referred to as distributed cooling applications are preferred. 分布式冷却应用是可要求单合成喷流致动器向多个位置提供冷却合成喷射流的情况。 Is distributed cooling applications may require a single synthetic jet actuator provides the cooling synthetic jet stream to a plurality of positions. 可选地,分布式冷却应用可要求合成喷流致动器向离致动器所在位置稍有些远的单个位置提供冷却流体流。 Alternatively, a distributed application may require cooling synthetic jet actuator provides cooling fluid flow to a single position where the actuator and slightly away from the actuator. 尽管不是限制性的例子,但这两个例子是常见的分布式冷却应用。 Although the example is not restrictive, but the two examples are common distributed cooling applications.

图4A表示分布式冷却合成喷流致动器60的一个实施例。 4A shows a distributed cooling synthetic jet actuator 60 of the embodiment. 为了便于说明,分布式冷却合成喷流致动器60的实施例已被设计成第二实施例40的改进形式。 For convenience of explanation, embodiments of a distributed cooling synthetic actuator 60 has been designed to spray a second modified form of Example 40. 这样,分布式冷却合成喷流致动器60包括确定了内室45的外壳47。 Thus, the distributed cooling synthetic jet actuator 60 includes a housing 45 determines the internal chamber 47. 外壳47和室45可采用任何几何构形,但为了便于讨论和理解,以横截面形式表示在图4A中的外壳47具有硬的侧壁44、硬的顶壁43和隔膜42,该隔膜能够变形到一定程度以允许隔膜42相对于室45向内和向外运动。 Housing 47 and the chamber 45 may take any geometric configuration, but for ease of discussion and understanding, represented in cross section in FIG. 4A housing 47 having a hard side wall 44, top wall 43 and the hard membrane 42, the membrane can be modified to a certain extent to allow the diaphragm 42 with respect to the inward and outward movement of chamber 45. 侧壁44的一部分形成了孔口46。 A portion of the sidewall 44 of the aperture 46 is formed. 如上所述,孔口46可具有任何几何形状。 As described above, the aperture 46 may have any geometric shape.

如以上实施例40,分布式冷却合成喷流致动器60也包括通过电导线39连接到隔膜42上的压电致动器47的电源及控制系统50。 As described in Example 40, the distributed cooling synthetic jet actuator 60 also includes a connection via an electrical line 39 to the diaphragm 42 of the piezoelectric actuator 47 of the power and control system 50. 如上所述,电源及控制系统50可以远离致动器60,或者例如可以连接到外壳47上或置于外壳47内。 As described above, power supply and control system 50 may be away from the actuator 60, for example, or may be connected to the housing 47 or 47 disposed within the housing.

示例性的分布式冷却装置60还包括通路或管道61。 Exemplary distributed cooling apparatus 60 further includes a conduit or passageway 61. 管道61的横截面形状可以与孔口46的横截面形状相似。 Cross-sectional shape of the conduit 61 may be similar to the cross-sectional shape of the aperture 46. 不过,管道61的横截面形状也可以完全不同于孔口46的形状。 However, the cross-sectional shape of the duct 61 may be completely different from the shape of the aperture 46. 例如,使用不同横截面形状能够更有效地引导从管道61射出的任何流体。 For example, the use of different cross-sectional shapes can be more efficiently direct any fluid emitted from the duct 61. 管道61优选地由包围内部区域63的硬壳62形成。 Conduit 61 is preferably surrounded by a hard shell 62 is formed inside region 63. 管道61还包括近侧端或连接端64和远侧端或开口端65。 61 further comprises a conduit connection end or proximal end 64 and a distal end or open end 65. 管道61优选地由塑料构成从而管道61会比较硬但仍然很轻。 Conduit 61 is preferably composed of a plastic pipe 61 so as to be more rigid but still very light. 可选地,管道61可由能够形成一种形状并保持该形状的柔性材料构成。 Alternatively, conduit 61 may be able to form one shape and maintain the shape of the flexible material. 在图4A中,管道61形成为基本呈蛇形。 In FIG. 4A, the pipe 61 is formed substantially serpentine. 管道61的形状对于本发明的原理并不重要,所表示的特定形状仅仅是为了图解说明本实施例60的原理而选出的。 Shape of the conduit 61 is not critical to the principles of the present invention, the particular shape shown is merely for illustrating the principle of the selected embodiment 60 of the present embodiment.

如图所示,管道61优选地连接到合成喷流致动器60的侧壁44上,从而致动器孔口以可流体连通的方式连接到管道61的内部区域63。 As shown, conduit 61 is preferably connected to the synthetic jet actuator 60 of the side wall 44, thereby actuating the orifice so as to be connected in fluid communication to the interior region 63 of the pipe 61. 在优选结构中,管道61的内径等于或大于孔口46的直径。 In a preferred construction, the inner diameter of the pipe 61 is equal to or larger than the diameter of the aperture 46. 这样,孔口46不会直接与外围环境48相通,或者换句话说,管道61完全盖住孔口46。 Thus, the aperture 46 does not directly communicate with the external environment 48, or in other words, the pipe 61 completely covers the apertures 46. 尽管管道61优选地“连接”到侧壁44上,但应该了解,外壳47和管道61可以由单件材料制成。 Although the conduit 61 is preferably "connected" to the side wall 44, it will be appreciated that the housing 47 and conduit 61 may be made of a single piece of material.

如以下更详细地阐述的那样,在操作过程中,涡流形成在管道出口端65的边缘处。 As set forth below in greater detail, during operation, a vortex is formed at an edge of the outlet end 65 of the conduit. 这些涡流卷起来并离开管道61的出口65。 These eddy currents rolled up and away from the outlet 65 of the duct 61. 这些涡流吸卷外围流体而在管道61的出口65处形成射流52。 The vortex suction roll peripheral fluid jet 52 is formed at the outlet 65 of duct 61. 实际上,使用管道61能够使射流52从管道61射出来,离开致动器本身。 Indeed, the use of jet pipes 61 can be made 52 emitted from the duct 61, leaving the actuator itself. 基本上,如果不存在管道61,那么原本要从合成喷流致动器孔口46射出的流体的合成喷流将改为从管道61的出口端65射出。 Basically, if the pipe 61 is not present, then the original jet stream from the synthesis of synthetic jet actuator aperture 46 to the exit of the fluid from the outlet end 65 of exit conduit 61. 本实施例60的该特征使得冷却系统的设计者能够把合成喷流致动器40定位在任何方便的位置处,且仍能通过简单地把管道61指向想要的位置而将流体流52引到比较远的位置。 The feature of this embodiment is that the designer of the cooling system 60 can be the synthetic jet actuator 40 is positioned at any convenient location, and still conduit 61 by simply pointing to the desired position and the fluid flow 52 primer to more distant locations.

例如,致动器40可定位在离将要被冷却的区域有一定距离的位置处,诸如在居中的位置处。 For example, actuator 40 may be positioned at a location some distance away from the area to be cooled, such as in a centered position. 管道61可以成形为通过散热器的散热翼片指引流体流。 Conduit 61 may be shaped to direct cooling fluid flow through the radiator fins. 合成喷流致动器不在散热器附近的事实一般会使通过散热器的散热翼片的流体流增大。 Synthetic jet actuator fact not in the vicinity of the radiator will generally increase the fluid flow through the radiator cooling fins. 实际上,如果致动器定位在散热翼片通路的入口处,那么经过散热翼片通路的流体流会由于致动器外壳的存在而被阻止。 Indeed, if the actuator is positioned at the entrance of the passage of heat dissipating fins, the fluid flow passage through the heat dissipating fins due to the presence of actuation of the actuator housing is prevented. 利用分布式冷却这就不成为问题。 Use of distributed cooling this is not a problem.

如上所述,管道61可以是预成形的或柔性的。 As described above, the duct 61 may be preformed or flexible. 如果是柔性的,那么设计者可以放置装置40然后使管道61成形为理想的形状。 If it is flexible, then the designer may place the duct means 40 and 61 are formed as ideal shape. 这对于改型应用很有益处。 This is very beneficial for retrofit applications. 不过,在大多数常见的实施例中,管道61会比较硬,从而可以在安装之前精细地调整整个冷却系统的设计。 However, in the most common embodiment, conduit 61 will be relatively hard, can be finely adjusted so that the overall design of the cooling system prior to installation.

如上所述,管道61的形状或尺寸对于本实施例60并不重要。 As described above, the shape or size of the conduit 61 is not critical to embodiment 60 embodiment. 不过,管道61的长度和/或形状会影响分布式冷却合成喷流致动器60的性能。 However, the length of the conduit 61 and / or shape can affect the performance of the distributed cooling synthetic jet actuator 60. 为了更好地说明这一点,应借助于分布式冷却装置60的操作。 To better illustrate this point, it should be distributed by means of the operation of the cooling device 60.

分布式冷却装置60中的合成喷流致动器40的操作类似于上述第二实施例中合成喷流致动器的操作。 Synthesis distributed jet cooling operation device 60 of the actuator 40 is similar to the above-described second embodiment in Synthetic jet actuators. 具体地说,压电致动器41以适当的频率,优选地以隔膜42的谐振频率发生振动。 Specifically, the piezoelectric actuator 41 at a suitable frequency, preferably at the resonance frequency of the diaphragm 42 vibrates. 该振动导致隔膜42以时间谐波运动的方式振动。 The vibrating diaphragm 42 so as to cause movement time harmonic vibration. 当隔膜42相对于内室45向内运动时,室45的容积减小,室45中的压力增大,在孔口46处形成压力梯度,流体从合成喷流致动器40的孔口46射出。 When the diaphragm 42 relative to the inner chamber 45 moving inwardly, the volume of chamber 45 decreases, the pressure in the chamber 45 is increased, a pressure gradient at the orifice 46, the fluid from the orifice synthetic jet actuator 40 of 46 injection. 由于在孔口46处没有外围流体引入,因此实际上流出孔口46的流体通常发生脉动,一般反映出由压电致动器41驱动的隔膜42的频率。 Since no fluid is introduced at the periphery of the aperture 46, and therefore out of the fluid orifice 46 is in fact usually occurs pulsation, generally reflect the frequency of the piezoelectric actuator 41 drives the diaphragm 42. 该流体脉冲进入连接在孔口46的管道61的内部区域63中。 The impulse of fluid into the interior region of the connecting duct 61 in the aperture 46 of 63. 当隔膜42相对于室45向外运动时,流体从管道内部63引入合成喷流致动器室45中。 When the diaphragm 42 with respect to the outward movement of chamber 45, the fluid 45 from the interior of the pipe 63 into a synthetic jet actuator chamber. 然后,当隔膜42继续其时间谐波振动并回到室45中时,流体再次从室45射入管道内部63中。 Then, when the diaphragm 42 continues its time harmonic vibration and back into the chamber 45, the fluid enters the chamber 45 again from the interior of the pipe 63.

图5A和5B表示分布式冷却装置60的合成喷流致动器40的操作过程中管道61的内部63范围内的流体相互作用。 FIGS. 5A and 5B show the range of the fluid within the interior 63 during operation of the cooling apparatus 60 is distributed synthetic jet actuator 40 in the duct 61 interaction. 当流体从合成喷流致动器室45进入管道61的内部63时,进入的流体充当“虚拟活塞”66。 When the fluid from the synthetic jet actuator 63 to enter the interior chamber 61 of the duct 45, incoming fluid acts as a "dummy piston" 66. 进入管道61内部63的流体66的脉冲压缩管道内部63中的流体,从而导致流体67从管道61的出口端65排出。 Pulse conduit 61 into the interior 63 of the fluid 66 inside the compressed fluid conduit 63, thereby causing the fluid 67 from the outlet end 65 of the discharge duct 61. 当隔膜42从合成喷流致动器室45向外运动时,“虚拟活塞”66从管道61的内部63向外移动,从管道内部63把流体抽入室45内,从而降低了管道61中的压力。 When the diaphragm 42 of the actuator chamber jet 45 moving outwardly from the composite, "dummy piston" 66 moving outwardly from the interior 63 of the pipe 61, inner pipe 63 draw fluid from inside the room entrance 45, thereby reducing the pipeline 61 pressure. 管道61中的这种低压在管道出口端65处形成了压力梯度,从而从周围48把流体吸入管道61。 This low pressure conduit 61 forms a pressure gradient at the outlet end of the conduit 65, so that the suction duct 61 from the surrounding fluid 48. 管道连接端64处的流体再一次充当“虚拟活塞”66,以时间谐波振动的方式操作。 At the end of the fluid conduit connector 64 once again acts as a "dummy piston" 66, a time-harmonic vibration manner.

管道61的中间部分68充当由管道61的壁62限定的另一个合成喷流致动器“室”69。 The intermediate portion 68 acts as a duct 61 defined by the wall 62 of another conduit 61 synthetic jet actuator "chamber" 69. 合成喷流致动器40的孔口46处的流体限定该“室”69,并充当对应于该虚拟合成喷流致动器“室”69的虚拟活塞66。 Synthesis of the fluid jet at the orifice 40 of the actuator 46 defines the "chamber" 69, and functions as corresponding to the virtual synthetic jet actuator "chamber" 69 of the piston 66 virtual. 离开和进入孔口46的、充当活塞66的流体形成了从管道61的出口端65射出的流体流67。 Leaving and entering the apertures 46, 66 acts as a fluid piston is formed from the outlet end 65 of the conduit 61 exiting fluid stream 67. 射出管道61的流体67在管道61的出口65处形成了涡流。 67 exit duct 61 in fluid vortex formed at the outlet 65 of duct 61. 这些涡流卷起来并离开管道出口65。 These eddy currents rolled up and away from the outlet duct 65. 当涡流形成并离开时,这些涡流卷吸着外围流体48以便在管道61的出口65处形成合成喷射流67。 When leaving the vortex formed and these vortices peripheral fluid sorbent volume 48 in order to form synthetic jet stream 67 at the outlet 65 of duct 61.

根据管道61的长度,可以确切地调整合成喷流致动器40的隔膜42的操作,以在管道61中形成虚拟合成喷流致动器。 The length of the duct 61, can be exactly adjusted synthetic jet actuator 40 of the diaphragm 42 operate to form in the pipe 61 in virtual combined jet actuator. 从以上讨论明显可知,且本领域普通技术人员会了解到,优选地,应当调整隔膜42的操作,以使从合成喷流致动器40的孔口46射出的空气脉冲66的频率是以管道61的谐振频率射出的。 As apparent from the above discussion, and one of ordinary skill in the art will understand that, preferably, the operation of the separator 42 should be adjusted so that the frequency of pulses from the composite air jet orifice 40 of the actuator 46 is emitted from the duct 66 61 the resonance frequency emitted. 实际上,管道61起到赫尔姆霍兹(Helmholtz)型谐振器的作用并能以类似方式工作。 In fact, the pipe 61 functions as Helmholtz (the Helmholtz) resonator and can work in a similar manner. 管道61的连接端64充当典型的Helmholtz谐振器的封闭端,而且还向谐振器提供激励力。 Connecting duct 61 to act as an typical Helmholtz resonator closed end 64, but also provides the excitation force to the resonator.

如果管道61的尺寸是已知的,那么本领域普通技术人员能够计算管道61的谐振频率。 If the size of the duct 61 is known, then those of ordinary skill in the art is able to calculate the resonant frequency of the duct 61. 然后,可以算出隔膜42振动的频率和幅度,以使从合成喷流致动器40孔口46射出的脉冲66以谐振频率激励管道61。 May then be calculated from the frequency and amplitude of vibration of the diaphragm 42, 66 so that the pulse from a synthetic jet orifice 40 of the actuator 46 to the resonant frequency of the excitation light emitted duct 61. 当然,这都能由适当的控制系统50自动控制。 Of course, this can be 50 automatically controlled by a suitable control system.

在分布式冷却合成喷流致动器的另一个示例性结构70中,合成喷流致动器40被构造成驱动许多管道。 Another exemplary structure of the jet in a distributed actuator 70 of cooled synthesis, the synthetic jet actuator 40 is configured to drive a number of pipes. 这种结构如图4B所示。 This structure shown in Figure 4B. 图4B是分布式冷却合成喷流致动器的切开顶视图。 FIG 4B is a distributed cooling synthetic jet actuator is a top view of the cut. 如图所示,致动器70的合成喷流致动器外壳47优选地有多个孔口46a,46b,46c,46d,46e,46f。 As shown, the synthetic jet actuator 70. The actuator housing 47 is preferably a plurality of apertures 46a, 46b, 46c, 46d, 46e, 46f. 在外壳47的外部连接有许多管道61a,61b,61c,61d,61e,61f,从而这些管道61a,61b,61c,61d,61e,61f对应于每一个孔口46a,46b,46c,46d,46e,46f。 Outside the housing 47 is connected to a number of pipes 61a, 61b, 61c, 61d, 61e, 61f, so that these pipes 61a, 61b, 61c, 61d, 61e, 61f corresponding to each orifice 46a, 46b, 46c, 46d, 46e , 46f. 管道61a,61b,61c,61d,61e,61f都可以构造成把流体流引向相同的区域,或者在优选的应用中,这样形成管道以把合成喷射流52a,52b,52c,52d,52e,52f引向分离的热区域或目标71a,71b,71c,71d,71e。 Pipes 61a, 61b, 61c, 61d, 61e, 61f can be configured to direct fluid flow towards the same region or in a preferred application, the duct is formed so that the synthetic jet at 52a, 52b, 52c, 52d, 52e, 52f towards the target or isolated hot zone 71a, 71b, 71c, 71d, 71e.

在分布式冷却装置的另一个实施例中,理想的是,用现有的方法把合成喷流致动器模块连接到另一表面上。 In another embodiment the distributed cooling apparatus, it is desirable that the conventional method using synthetic jet actuator module connected to the other surface. 例如,如果分布式冷却装置将使用在改型的应用中,那么可能不是已有的连接方法。 For example, if the cooling means will be used in a distributed application in a modified, it may not be connected to the existing methods. 在这种情况下,理想的是,把合成喷流致动器40的顶壁43构造成容易粘附到表面上。 In this case, it is desirable that the synthetic jet actuator 40 of the top wall 43 is configured to be easily adhered to the surface. 合成喷流致动器40可以被“贴”到表面上。 Synthetic jet actuator 40 may be "attached" to the surface. 这能通过使用双面胶带、两面都有粘合剂的泡沫塑料等等来实现。 This can double-sided tape, adhesive on both sides and the like to achieve a foam.

B.第二例:多致动器装置在分布式冷却装置的一些实施方式中,理想的是产生多个合成喷射流。 B. Second Example: actuator means multiple embodiments of distributed some of the cooling device, it is desirable to produce a plurality of synthetic jet. 如上所述,单合成喷流致动器40可以驱动多个管道,从而产生流体的多个分布式喷射流。 As described above, the single synthetic jet actuator 40 may drive a plurality of conduits, thereby producing a plurality of fluid jets distributed. 当然,这不是多合成喷流分布式冷却装置的仅有的可能实施方式。 Of course, the only possible embodiment it is not distributed multiple synthetic jet cooling device. 另一个实施例可包括驱动多个管道的多个合成喷流致动器,从而发射出多个合成喷射流。 Another embodiment may include a plurality of driving a plurality of synthetic jet pipes actuator to emit a plurality of synthetic jet. 该实施例的管道可以指向不同的区域、不同的散热器通路或者都指向相同的位置。 Duct of this embodiment may be directed to different areas or different passage radiator point to the same location.

多致动器型分布式冷却装置80的横截面侧视图如图7所示。 80 is a cross-sectional multi-actuator distributed cooling device side as shown in Fig. 所示外壳82的一个增压间83由装置82的底面87、前壁88和后壁89限定。 A booster housing 82 shown in FIG. 83 between the front wall 88 and back wall 89 is defined by a bottom surface 87 of the device 82. 前壁88和后壁89的每一个都形成一对上平台91,92和一对下平台93,94。 A front wall 88 and rear wall 89 each are formed of a pair of upper platforms 91, 92 and a pair of lower platforms 93 and 94. 这些平台91,92,93,94优选地由与壁88,89相同的材料制成,而不仅仅是粘附到壁88,89上。 These platforms 91,92, 93,94 are preferably made of the same material as the walls 88, 89, rather than adhering to the walls 88, 89. 当然,这不是多致动器型分布式冷却装置80的必要特征。 Of course, this is not essential features of the multi-type actuator means 80 is distributed cooling. 此外,顶壁95(如图8所示)可以安装在装置80上以密封增压间83。 Further, the top wall 95 (FIG. 8) may be mounted on device 80 to seal between the booster 83.

图8表示有两个致动器96,97置于增压间83之内且顶壁95安装在增压间83上方以后的图7所示的装置。 8 shows the apparatus shown in FIG. 7 has a top wall of the inner 83 and between the booster 95 after the booster is mounted between the top 83 of the two actuators 96, 97 is placed. 如图所示,第一致动器96被支撑在上平台91,92上且第二致动器97被支撑在下平台93,94上。 As shown, the first actuator 96 is supported on the platform 91, 92 and the second actuator 97 is supported on the lower platforms 93 and 94. 这两个致动器96,97优选地包括柔性隔膜98、99,压电致动器101、102安装到柔性隔膜98、99上。 These two actuators 96, 97 preferably comprises a flexible diaphragm 98 and 99, the piezoelectric actuator 101 is mounted to the flexible diaphragm 98, 99. 优选的致动器96,97是以上关于实施例40所述的弹性体或聚合物致动器。 The preferred actuator 96, 97 of the 40 or more elastomer or polymer actuator on the embodiment. 参见图2。 See Figure 2. 对于这里所述的装置80也可以使用其他致动器。 For the apparatus 80 described herein may be used in other actuators. 不过,弹性体/聚合物致动器由于其简单的外形设计、强力的致动以及低廉的成本而成为优选。 However, elastomer / polymer actuator designs due to its simple shape, strong and low cost actuator becomes preferable.

通过电导线(未示出)向致动器96,97提供电能和控制。 Providing power and control to the actuators 96, 97 via electrical lines (not shown). 这些导线通常通过切开外壳82的上下侧壁85,86的四个小沟道103a,103b,103c(在图6中仅示出三个)进入外壳82内。 These leads are often cut by the vertical side walls 85, 86 of the housing 82 four small channels 103a, 103b, 103c (in FIG. 6, only three shown) into the housing 82. 实际上,可以预见整个控制电路(未示出)可设置在这些沟道103a,103b,103c中。 Indeed, it is contemplated the entire control circuit (not shown) may be provided in these channels 103a, 103b, 103c in. 然后,优选地仅有电能供应到这些沟道103a,103b,103c和它们包含的控制硬件中。 Then preferably only supplied to power these channels 103a, 103b, 103c, and they contain the control hardware.

致动器96,97优选地紧固到装置外壳82中的平台91,92,93,94上。 The actuator 96, 97 is preferably fastened to the platform 82 in the device housing 91,92, 93,94. 这优选地通过使用一种类型的粘合剂来实现。 This is preferably achieved by using one type of adhesive. 由于隔膜98,99的材料优选的是弹性体或聚合物,而外壳82的优选材料是塑料,因此本领域普通技术人员会很容易选择适当的粘合剂或其他连接机构。 98 and 99 since the diaphragm material is preferably an elastomer or polymer and preferably is a plastic material of the housing 82, and therefore one of ordinary skill in the art will readily select an appropriate adhesive or other attachment mechanism.

一旦致动器96,97紧固在装置外壳82的内部,则装置增压间83实质上被分成三个部分。 Once the actuator 96, 97 is fastened in the interior of the device housing 82, between the pressurizing means 83 is substantially divided into three parts. 致动器96,97的设置形成了三个分离的室,从而形成三个分离但又相关的合成喷流致动器。 Setting the actuator 96, 97 is formed of three separate chambers, thereby forming three separate but related synthetic jet actuators. 第一或底室105由外壳底壁87、外壳前壁88、外壳后壁89和第二致动器97限定。 The first chamber 105 from the bottom or bottom wall of the housing 87, the housing front wall 88, rear wall 89 of the housing and a second actuator 97 is defined. 第二室106由第一致动器96、前壁88、后壁89和第二致动器97限定。 The second chamber 106 by a first actuator 96, a front wall 88, a rear wall 89 and a second actuator 97 is defined. 第三或顶室107由第一致动器96、前壁88、后壁89和顶壁95限定。 The third or top chamber 107 by the first actuator 96, a front wall 88, a rear wall 89 and top wall 95 is defined.

回想以上分布式冷却装置60的实施例具有从室45指向单个管道61的单个孔口46(图4A)。 Recall that the above embodiments the cooling apparatus 60 having distributed from a single point to a single orifice 45 chamber 61 pipe 46 (FIG. 4A). 不过,在本实施例80中,每一个室105,106,107有一个或多个孔口108。 However, in the present embodiment 80, each chamber has one or more orifices 105, 106, 108. 在实施例80中,每一个室105,106,107有两个形成到装置外壳82的前壁88内的孔口。 In Example 80, each of the chambers 105, 106 has two apertures formed within the front wall 88 to the apparatus housing 82. 每一个孔口还以可流体连通的方式连接到由外壳82的前壁88形成的一个管道81。 Each orifice is also in fluid communication manner a duct 81 connected to the front wall 88 of housing 82 is formed. 当然,不必每一个室105,106,107都有两个孔口108和管道81。 Of course, each of the chambers 105, 106 need not have two apertures 108 and conduit 81. 如果有多于或少于两个孔口108和管道81,或者如果对于每一个室105,106,107有不同数量的孔口和管道,本实施例80也可以工作。 If more or less than two apertures 108 and conduit 81, or a different number of orifices and conduits 105, 106 if, for each chamber, embodiment 80 of the present embodiment can work.

管道81优选地在基本上同一水平面内连接到外壳82,如图6所示。 Conduit 81 is preferably substantially in the same horizontal plane is connected to the housing 82, as shown in FIG. 为此,图7和图8看似仅表示了一个管道81(和一个孔口108),该管道在接近外壳前壁88的中点处连接到外壳82。 For this purpose, FIG. 7 and FIG. 8 shows only one appears to line 81 (and an aperture 108), the duct near the midpoint of the housing front wall 88 is connected to the housing 82. 管道81包括连接端109,连接到外壳前壁88,以及包括流体出口端110,所述流体出口端以可流体连通的方式使管道内部111连通到外围流体112。 81 comprises a pipe connection end 109, attached to the housing front wall 88, and comprising a fluid outlet end 110, a fluid outlet end so as to be in fluid communication with the pipe 111 inside the fluid communication 112 to the peripheral.

由于管道81优选地都在同一水平面内连接到外壳82上,且室105,106,107不在同一水平面内,因此,优选地使用成形通道113将每一个室105,106,107以可流体连通的方式连接到由特定的合成喷流致动器所服务的孔口108和管道81。 Since the conduit 81 is preferably connected in the same horizontal plane to the housing 82, and the chamber 105, 106 is not in the same horizontal plane, it is preferable to use a shaped channel 113 of each chamber 105, 106 to be in fluid communication aperture 108 and connected to the conduit 81 by a specific synthetic jet actuator served.

这些具有端口的通道113表示在图9的切开剖面图中。 These channels have a port 113 is shown in cross-sectional cut view of FIG. 9. 此外,图10表示这三个室105,106,107和每一个室105,106,107所服务的孔口108a-f的切开图。 Further, FIG. 10 shows three chambers 105, 106 and each of the chambers 105, 106 of the cut apertures 108a-f of FIG services. 作为举例,图10中,第一室105有两个孔口108e,108f;第二室106有两个孔口108c,108d;而第三室107有两个孔口108a,108b。 By way of example, in FIG. 10, a first chamber 105 has two apertures 108e, 108f; the second chamber 106 has two apertures 108c, 108d; and the third chamber 107 with two orifices 108a, 108b. 如从图9和图10可见,外壳82中的三个室105,106,107的横截面不必是矩形,也可以是奇特的形状从而把流体引到由每一个室105,106,107所服务的不同管道81。 As seen from FIGS. 9 and 10 can be seen in cross-section three chambers 105, 106 of the housing 82 need not be rectangular, or may be oddly shaped such that the fluid to a chamber 105, 106 by each of the services the 81 different channels.

当然,在可选实施例中,管道81不必在相同的水平面内连接到外壳82上。 Of course, in an alternative embodiment, the conduit 81 need not be connected to the housing 82 in the same horizontal plane. 例如,由每一个室105,106,107提供服务的管道81可以直接连接到室105,106,107。 For example, the duct 81 served by each of the chambers 105, 106, 105, 106 may be directly connected to the chamber. 然后,室105,106,107可以这样构造,使得它们有基本呈矩形的横截面。 Then, the chamber 106 and 107 may be configured such that they have a substantially rectangular cross section.

现在将说明示例性的多致动器型分布式冷却装置80的工作,同时具体讨论一个“增压间”83。 We will now be described an exemplary multi-actuator distributed cooling apparatus 80 is working, while specific discussion "between booster" 83 a. 应该了解的是,其他“增压间”83的工作是相似的。 It should be understood that other "booster between" work 83 is similar. 工作时,由控制系统(未示出)致使两个隔膜96,97按时间谐波运动方式发生振动,其中该控制系统控制每一个隔膜98,99上的每一个压电致动器101,102。 In operation, by a control system (not shown) so that two diaphragms 96 and 97 vibrate time harmonic motion, wherein the control system controls each of the piezoelectric diaphragms 98, 99 on each actuator 101 and 102 . 隔膜98,99优选地这样致动使得两个隔膜98,99彼此异相地振动。 Separator 98, 99 is preferably actuated so that the two diaphragms 98 and 99 relative to each other different vibration.

由于两个致动器96,97彼此相向运动,所以第二室106的容积减小,而顶室107和底室105的容积增大。 Since the two actuators 96, 97 move toward each other, the volume of the second chamber 106 is reduced and the volume of the top chamber 107 and bottom chamber 105 increases. 因此,第二室106推动流体从室106进入连接到该室106的管道81内部111中。 Thus, the second chamber 106 push the fluid from the chamber 106 into the chamber 106 is connected to the conduit 81 in the interior 111. 回忆与以上单致动器实施例60有关的讨论,该使流体进入管道内部111的推动过程起到类似于流体的“虚拟活塞”的作用。 Memories and above the single actuator embodiment discussed relating to Example 60, the fluid conduit into the interior of the push process 111 act as a "virtual piston" act like a fluid. 参见以上用于阐述该过程的有关图5A和5B的描述。 Referring to FIG. 5A above with respect to the process described for explaining and 5B. 该虚拟活塞进入管道81内部111,压缩管道内部111的流体,从而使得在连接到该第二室106的管道81出口端110处形成流体的合成喷射流115。 The virtual line 81 enters the interior of the piston 111, internal conduit 111 of the compressed fluid, such that synthetic jet 115 is formed at a fluid conduit connected to the outlet 81 of the second end 110 of the chamber 106.

顶室107和底室105承受反作用。 Top chamber 107 and bottom chamber 105 to withstand the reaction. 具体地说,由于两个隔膜98,99彼此相向运动,所以顶室和底室107,105把流体从连接到这些室107,105的管道81内部111引入。 Specifically, since the two diaphragms 98, 99 move toward each other, the top chamber and a bottom chamber 107,105 is introduced from the fluid pipe 81 connected to the interior of the chamber 111 107,105. 这使得流体的“虚拟活塞”进入顶室和底室107,105,从而使连接到这些室107,105的管道81的出口端110从外围112引入流体。 This allows the fluid "virtual piston" into the top chamber and a bottom chamber 107,105, so that the outlet duct 81 is connected to the chambers 107,105 the fluid is introduced from the end 110 of the periphery 112.

当隔膜98,99远离彼此地振动时,第二室的容积增大,而流体从外围112被引入连接到该室106的管道81中。 When the vibrating diaphragm 98, 99 away from each other, the volume of the second chamber is increased, and the fluid is introduced into line 81 connected to the chamber 106 from the peripheral 112. 当然,顶室和底室107,105的容积也类似地减小。 Of course, the volume of the top chamber and a bottom chamber 107,105 is similarly reduced. 这使得在连接到这两个室107,105的管道81出口端110处形成流体的合成喷射流115。 This synthetic jet 115 is formed such that the fluid in the two chambers is connected to the outlet end of the duct 81 of 110 107,105.

如本领域普通技术人员会了解的那样,多致动器型分布式冷却装置80的工作原理与上述基本的分布式冷却装置60非常相似。 As one of ordinary skill in the art will appreciate, multiple actuator distributed cooling apparatus 80 works with said primary distributed cooling device 60 is very similar. 例如,该实施例80的管道81以上述关于单致动器型分布式冷却装置60的方式充当Helmholtz谐振器。 For example, line 81 of the embodiment described above in Example 80 for the single actuator distributed cooling apparatus 60 serves as a Helmholtz resonator.

多致动器型分布式冷却装置80的一个常见实施方式如图11A和11B所示。 Multi actuator distributed cooling apparatus 80 is a common embodiment in FIG. 11A and 11B. 当然,根据系统的热管理需求和装置80的结构,对于装置80而言许多其他实施方式也是可能的。 Of course, the structure of the thermal management needs of the system and apparatus 80, to the device 80 for many other embodiments are possible. 该实施方式120不限制装置80的实施范围。 Scope device 80 of this embodiment 120 is not limiting. 提出的示例性实施方式仅仅是为了更好地描述本实施例80的特征。 Exemplary embodiments set forth merely to better describe the features of embodiment 80 of the present embodiment.

示例性实施方式120涉及使用挤压的散热器121,以便从热的目标122把热量传走。 Exemplary embodiments relate to the use of extruded heat sink 120 121, in order to transfer heat away from the heat of the target 122. 多致动器型分布式冷却装置80这样设置:使得装置80中的每一个管道81与通过散热器121的一系列散热翼片124形成的一系列通路123排列成行,从而喷射流125流经散热翼片124之间的通路123。 Multi actuator distributed cooling apparatus 80 arranged such: that each conduit 81, 80 and 123 series of aligned passage 124 formed through a series of heat sink fins 121 of the heat dissipating means, so that heat flowing through the jet 125 passage 123 between the flap 124. 该喷射流125又夹带着第二冷却气流126,该气流被强制进入散热器121的通路123。 The jet 125 and carries a second cooling air flow 126, the gas stream is forced into the passage 123 of the heat sink 121.

在该冷却模块80的另一用途中,利用管道81的合成喷流阵列来减少通过风扇驱动流127冷却的散热器121中的支流130。 In another use of the cooling module 80, a synthetic jet array by conduit 81 to reduce the fan drive cooling flow branch 127 of the radiator 121 130. 图12A表示没有合成喷流致动器80的情况。 12A shows the case where no synthetic jet actuator 80. 在该实施例中,风扇128通过散热片121的散热翼片124之间的通路123吸引流体流127。 In this embodiment, the passage 123 between the heat dissipating fins 124 of the fan 128 through the heat sink 121 127 a suction fluid flow. 不过,由于散热片121的通路123所产生的压降,大部分气流130绕过散热片121。 However, the pressure drop due to the passage 123 of the fins 121 generated, most of the stream 130 bypassing the heat sink 121. 这是许多应用中,比如叶片服务器(blade server)、电信架(telecom racks)等,常遇到的问题,其中元件板之间的间隔很窄,且存在大的风扇组以试图驱动大量气流通过安装在热元件上的散热片。 This is a problem for many applications, such as blade server (blade server), the telecommunications carrier (telecom racks) and the like, often encountered in which the spacing between the plate elements very narrow, and there is a large group to attempt to drive the fan air flow through a large number of fins mounted on the heat element.

在该实施方式中,如图12B所示,合成喷流致动器这样设置:使得致动器80的管道81将它们的流体流115排空到散热片121的通路123中。 In this embodiment, as shown in FIG. 12B, the synthetic jet actuator is arranged such: line 81 such that actuator 80 is emptied their fluid flow passage 123 to the heat sink 115 121. 应该指出的是,由于装置80的分布式特性,致动器能设置在散热片121的平面下方,从而防止被流体流干扰。 It should be noted that, due to the distributed nature of the device 80, the actuator is disposed below the plane of the fins 121, thereby preventing the fluid stream interference. 当致动器80开始工作时,切向的合成喷流115被引向散热片121的左边缘附近。 When the actuator 80 starts working, a tangential synthetic jet 115 is directed to the vicinity of the left edge of the fin 121. 风扇128持续工作。 128 fans continue to work. 低压高动量的合成喷流导致产生气流130的有效夹带流131,该气流130先前是从散热片121旁边经过的。 Synthesis of low-pressure high-momentum jet stream results in an effective entrained stream 131 130, the airflow 130 from the previous 121 next fin passes.

应强调的是,本发明的上述实施例,尤其是任何“优选”实施例仅仅是可能的实施方式的例子,仅仅为了清楚地理解本发明的原理而陈述。 It should be emphasized that the above-described embodiments of the present invention, particularly any "preferred" embodiments, are merely examples of possible embodiments, only for a clear understanding of the principles of the present invention are set forth. 可以对本发明的上述实施例进行许多变更和修改而不会在实质上脱离本发明的精神和原理。 Numerous variations and modifications may be made to the above described embodiments of the invention without departing substantially from the spirit and principles of the invention. 所有这些修改和变更将包括在本说明书和本发明以及由以下权利要求所保护的范围以内。 All such modifications and variations be included within the scope of, and protected by the following claims and the specification of the present invention.
