[0032] 图2示出了依照本发明实施例的闭式气流循环系统的俯视示意图。 [0032] FIG. 2 shows a closed air flow according to an embodiment of the present invention, a schematic plan view of the circulatory system. 在本发明一实施例中,内、外腔的结构是由一组嵌套同心圆结构的内、外腔壁限定的:如图2所示,内圆是内腔壁,其内部为内腔1 ;外圆是外腔壁,内圆与外圆之间的部分为外腔2。 In one embodiment of the invention, the structure of the inner and outer chamber by a set of nested concentric inner structure, outer cavity wall defined by: 2, the inner circle is the lumen wall, the inside of the lumen 1; cylindrical outer cavity wall, between the inner circle and the outer part of the outer chamber 2. 在本发明的另一实施例中,内、外腔壁采用了多边形结构。 In another embodiment of the present invention, the inner and outer cavity wall with a polygonal structure. 当然,本领域技术人员应该理解,在本发明中, 风洞内、外腔壁的横截面可以采用各种形状,例如附图2中的圆形、多边形,并且可以采用同心结构或非同心结构,或者采用相同形状的组合或不同形状的组合,例如圆形内腔壁与多边形外腔壁的组合。 Of course, those skilled in the art will appreciate that, in the present invention, the wind tunnel, the cross-section of the outer chamber wall may take various shapes, e.g., in Figure 2 the circular, polygonal, and may be concentric or non-concentric structure , or a combination of the same shape or a combination of different shapes, such as a combination of circular and polygonal outer cavity wall of the cavity wall. 本发明在这一方面不受限制。 The present invention is not limited in this regard. 在较佳实施中,内、外腔壁可以采用同心圆结构,也可以采用同心正多边形,如正8、10、12边形,这样在选材与安装上可以大大降低成本费用,也可以为模块化设计提供基本条件。 In a preferred embodiment, the inner and outer cavity wall concentric structure can also be used concentric regular polygon, such as n-8,10,12-gon, so in the selection and installation can greatly reduce costs, but also for the module Design provides the basic conditions. 此外,根据空气动力学的计算,外腔的横截面面积与内腔的横截面面积之比较佳地大于2。 In addition, based on the calculated aerodynamic cross-sectional area and cross-sectional area of the lumen of the outer chamber 2 greater than the best comparison. 与传统的风洞大回合循环的方式截然不同,本发明的风洞结构非常紧凑,能够有效地节省风洞的占地面积,为娱乐风洞的商业推广带来极大的好处。 With the traditional way different wind tunnel large round cycle, wind tunnel structure of the present invention is very compact, it can effectively save wind tunnel area, to bring great benefits to the wind tunnel entertainment business promotion.

[0033] 风洞的动力装置在风洞系统的地位非常重要,直接关系到风洞的建设造价、运行效率以及运行维护成本。 [0033] the status of the power plant in the wind tunnel wind tunnel system is very important, directly related to the wind tunnel construction costs, operational efficiency, and operation and maintenance costs. 传统的风洞大多采用单一的大功率电机,功率基本上大于1000KW, 建安造价高,营运成本大,商业运转比较困难,这也是制约娱乐风洞市场推广的主要原因之一。 Most of the traditional wind tunnel using a single high-power motors, power substantially greater than 1000KW, high installation cost, high operating costs, more difficult business operation, which is one of the main entertainment wind tunnel marketing constraints. 本发明的风洞采用多个动力子系统,即将风洞所需的动力总功率分解为多个小功率的动力子系统。 The present invention employs a plurality of wind tunnel power subsystem, i.e. the total power of the power required for the wind tunnel divided into a plurality of small power power subsystem. 在本发明一实施例中,动力子系统是包括动力模块的一体式、模块化动力子系统,可以由电机和航空推进器构成。 In one embodiment of the invention, the power subsystem including a power module is integrated, modular power subsystems may be constituted by the motor and aviation propulsion. 在一实施例中,采用多个70至120KW的高效电机,配以高效航空推进器,组成多个一体式的模块化动力子系统3。 In one embodiment, the use of more than 70 to 120KW of high-efficiency motors, with efficient aerospace propulsion, consisting of more than one type of modular power subsystem 3. 这些动力子系统3的外形几何尺寸可以控制在2*2*2米之内。 The power subsystem 3 outline geometry can be controlled within 2 * 2 * 2 meters. 如图3所示,可以根据风洞内腔的风速要求,也可以根据功率与功能的需求确定所需动力子系统3的数量,并可将这些动力子系统3设置在本发明的风洞外腔2内的任何位置,例如可以安置在外腔2的中部或底部。 3, according to the requirements of wind tunnel cavity, also according to the power demand to determine the number and function of the desired power subsystem 3, subsystem 3 can be provided in which the power of the present invention outside the wind tunnel anywhere within the chamber 2, for example, or may be arranged outside the middle of the bottom of the chamber 2. 较佳地,本发明的动力系统可以包括6-12个分散在外腔内的动力子系统。 Preferably, the power system of the present invention may comprise 6-12 outer chamber dispersed power subsystem. 若将动力子系统3设置在本发明的风洞外腔的中部,动力推进气流的方向垂直朝下;若将动力子系统3设置在本发明的风洞外腔的底部,动力推进气流的方向平行地面并导向内腔。 If the power subsystem 3 is provided in the middle of the power tunnel outer chamber of the present invention to promote vertical downward airflow direction; If the power subsystem 3 is provided at the bottom of the wind tunnel of the outer chamber of the present invention, the driving force behind the direction of airflow parallel to the ground and guide lumen. 这种风洞的动力系统设计灵活自由,可以完全解决由于噪音或结构支撑等因素给风洞设计带来的问题:现有风洞的电机系统大多采用一个大功率电机,并安置在风洞的顶部,而大功率电机的重量大多超过几吨甚至几十吨, 这对风洞的支撑结构要求比较高,本发明将大功率的电机分解为多个小功率的电机,使得风洞的整体结构分布均勻稳定;同时,本发明的动力子系统完全处于风洞的外腔2内,风洞气流运动产生的噪音完全被阻隔在内腔1与外腔2的循环空间中,使得风洞外部的环境噪音大大降低,这与欧美一些开放式的娱乐风洞相比环境友好程度要高许多。 This wind tunnel power system design flexibility and freedom, can be completely solved due to noise or other factors structural support designed to bring the issue to the wind tunnel: The existing tunnel of the motor system they use a high-power motor, and placed in the wind tunnel top, while most of the weight of the motor power more than a few tons or even tens of tons, which the wind tunnel of the support structure is relatively high, the power of the motor of the present invention is divided into a plurality of small power motors, making the overall structure of the wind tunnel uniform and stable; the same time, the power subsystem of the present invention is well within the outer chamber 2 wind tunnel, the noise generated by wind tunnel air movement completely block the lumen 1 and 2 of external cavity circulation space, making the tunnel outside Environmental noise is greatly reduced, which compared with some European and American entertainment wind tunnel open much higher degree of environmental friendliness. 在一实施例中, 我们制造了总功率达900KW的风洞,采用10组90KW的动力子系统放置在外腔的底部,内腔直径约4米。 In one embodiment, we made a total power of 900KW wind tunnel, using 10 groups 90KW of power subsystem is placed at the bottom of the outer chamber, about 4 m diameter of the lumen.
