具体实施方式Detailed ways
本申请第一实施例提供一种模块化间接蒸发冷却系统,该系统利用可以自动旋转的喷淋组件进行喷淋,从而可以有效简化现有技术中的喷淋组件的设备,从而降低维护成本;另外现有技术中需要给喷淋设备提供电动机来带动喷淋设备移动,而本申请中的喷淋组件中的喷臂可以依靠自身喷液提供动力而旋转,从而可以节约能源;另外,利用水冷的方式进行换热具有高效节能的好处。The first embodiment of the present application provides a modular indirect evaporative cooling system, which uses a spray assembly that can automatically rotate for spraying, thereby effectively simplifying the equipment of the spraying assembly in the prior art, thereby reducing maintenance costs; In addition, in the prior art, it is necessary to provide a motor for the spray equipment to drive the spray equipment to move, while the spray arm in the spray assembly in the present application can be rotated by the power provided by its own spray liquid, thereby saving energy; in addition, the use of water cooling The heat exchange method has the advantages of high efficiency and energy saving.
水蒸发吸热,具有冷却功能,这种物理现象早为人类所利用,例如在房间内泼点水,可以使室温有所下降。干热气候区(如西北部地区等),夏季空气的干球温度高,含湿量低,其室外干燥空气不仅可直接利用来消除空调区的湿负荷,还可以通过间接蒸发冷却等来消除空调区的热负荷。在新疆、内蒙古、甘肃、宁夏、青海、西藏等地区,应用蒸发冷却技术可大量节约空调系统的消耗。Water evaporates and absorbs heat and has a cooling function. This physical phenomenon has been used by humans for a long time. For example, splashing some water in a room can lower the room temperature. In hot and dry climate regions (such as the northwest region, etc.), the dry bulb temperature of the air in summer is high and the moisture content is low. The outdoor dry air can not only be used directly to eliminate the humidity load of the air-conditioning area, but also can be eliminated by indirect evaporative cooling, etc. The heat load of the air-conditioned area. In Xinjiang, Inner Mongolia, Gansu, Ningxia, Qinghai, Tibet and other regions, the application of evaporative cooling technology can greatly save the consumption of air conditioning systems.
蒸发冷却分为直接蒸发冷却(Direct Evaporative Cooling,缩写为DEC)和间接蒸发冷却(Indirect Evaporative Cooling,缩写为IEC)。直接蒸发冷却是指干燥空气和水直接接触的冷却过程,空气处理过程中空气和水之间的传热、传质同时发生且相互影响,空气处理过程为绝热降温加湿过程,其极限温度能达到空气的湿球温度。Evaporative cooling is divided into direct evaporative cooling (Direct Evaporative Cooling, abbreviated as DEC) and indirect evaporative cooling (Indirect Evaporative Cooling, abbreviated as IEC). Direct evaporative cooling refers to the cooling process in which dry air and water are in direct contact. During the air treatment process, heat and mass transfer between air and water occur simultaneously and affect each other. The air treatment process is an adiabatic cooling and humidification process, and its limit temperature can reach The wet bulb temperature of the air.
在某些情况下,当对处理空气有进一步的要求,如要求较低含湿量或比焓时,就应采用间接蒸发冷却。间接蒸发冷却可避免传热、传质的相互影响,空气处理过程为等湿降温过程,其极限温度能达到空气的露点温度。间接蒸发冷却又可分为两类:(1)利用直接蒸发冷却的二次空气通过换热器对一次空气(被冷却空气)进行干冷却;(2)利用蒸发冷却获得的冷水通过换热器对空气进行冷却。本实施例中利用的就是第一种方式:利用直接蒸发冷却的二次空气通过换热器对一次空气(被冷却空气)进行干冷却。In some cases, indirect evaporative cooling should be used when there are further requirements for the process air, such as lower moisture content or specific enthalpy. Indirect evaporative cooling can avoid the mutual influence of heat transfer and mass transfer. The air treatment process is an isohumidity cooling process, and its limit temperature can reach the dew point temperature of the air. Indirect evaporative cooling can be divided into two categories: (1) use the secondary air of direct evaporative cooling to dry-cool the primary air (cooled air) through the heat exchanger; (2) use the cold water obtained by evaporative cooling to pass through the heat exchanger Cool the air. In this embodiment, the first method is used: the primary air (cooled air) is dry-cooled by using the secondary air directly evaporatively cooled through the heat exchanger.
正如背景技术描述,现有技术中的一些数据中心也采用间接蒸发冷却的方法进行降温,这种方法能耗低、制冷效果好,但是现有技术中的间接蒸发冷却系统喷嘴数量多,增加喷淋系统成本,并且喷嘴容易堵塞,维护成本高,并且喷淋水颗粒大,不易蒸发、冷却效果不好。As described in the background art, some data centers in the prior art also use the indirect evaporative cooling method to cool down. This method has low energy consumption and good cooling effect, but the indirect evaporative cooling system in the prior art has a large number of nozzles, which increases the The cost of the shower system is high, the nozzles are easily blocked, the maintenance cost is high, and the spray water particles are large, not easy to evaporate, and the cooling effect is not good.

如图1A-5所示,本实施例提供一种模块化间接蒸发冷却系统10,可以包括:壳 体20以及设置在壳体20内部的换热装置20a;其中,换热装置20a包括蒸发换热芯体30和喷淋组件40;喷淋组件40包括进液管41、喷臂42和喷嘴44;进液管41与喷臂42旋转连接,且进液管41的出液口411与喷臂42连通;多个喷嘴44间隔设置在喷臂42上,喷嘴44朝向蒸发换热芯体30的第一面31;喷臂42的至少一端设置有至少一个旋转喷口421,旋转喷口421用于向外喷液时驱动喷臂42旋转。As shown in FIGS. 1A-5 , the present embodiment provides a modular indirect evaporative cooling system 10 , which may include: a casing 20 and a heat exchange device 20 a disposed inside the casing 20 ; wherein the heat exchange device 20 a includes an evaporative heat exchanger The hot core 30 and the spray assembly 40; the spray assembly 40 includes a liquid inlet pipe 41, a spray arm 42 and a nozzle 44; The arms 42 are in communication; a plurality of nozzles 44 are arranged on the spray arms 42 at intervals, and the nozzles 44 face the first surface 31 of the evaporation heat exchange core 30; at least one end of the spray arms 42 is provided with at least one rotating nozzle 421, and the rotating nozzle 421 is used for The spray arm 42 is driven to rotate when the liquid is sprayed outward.
本申请实施例提供的模块化间接蒸发冷却系统10,通过在喷淋组件40的喷臂42上设置旋转喷口421,这样喷臂42在通入液体后依靠液体喷射产生的反作用力驱动喷臂42向液体喷射的反方向转动,从而实现喷臂42依靠自身动力转动的目的,这样可以扩大喷臂42辐射的范围,并且无需电力传动机构的带动,从而可以简化喷淋组件40的结构,降低维护设备的成本。通过在喷臂42上间隔设置多个喷嘴44,这样在喷臂42转动时,喷臂42就可以带动喷嘴44在喷臂42的旋转空间内进行喷淋,从而达到对蒸发换热芯体30冷却的效果。In the modular indirect evaporative cooling system 10 provided by the embodiment of the present application, the rotating nozzle 421 is provided on the spray arm 42 of the spray assembly 40, so that the spray arm 42 drives the spray arm 42 by the reaction force generated by the liquid spray after the spray arm 42 enters the liquid. Rotate in the opposite direction of the liquid spray, so as to realize the purpose of rotating the spray arm 42 by its own power, so that the radiation range of the spray arm 42 can be expanded, and the drive of the electric transmission mechanism is not required, thereby simplifying the structure of the spray assembly 40 and reducing maintenance. cost of equipment. By arranging a plurality of nozzles 44 on the spray arm 42 at intervals, when the spray arm 42 rotates, the spray arm 42 can drive the nozzles 44 to spray in the rotating space of the spray arm 42, so as to achieve the evaporative heat exchange core 30. cooling effect.
需要说明的是,蒸发换热芯体30可以为图中所示的六面体结构,也可以为球形结构或者其它形状的结构,其形状不构成对本申请技术方案保护范围的限制,只要是能够实现其交换热量的功能即可。It should be noted that the evaporative heat exchange core 30 may be a hexahedral structure as shown in the figure, a spherical structure or a structure of other shapes. The function of exchanging heat is enough.
优选地,将喷嘴44朝向蒸发换热芯体30的第一面31,从而可以方便地使喷嘴44喷射的喷淋液体直接进入到蒸发换热芯体30内部,进而对进入蒸发换热芯体30内部的热空气进行冷却,提高喷淋液体的利用率,进而提高冷却的效率。Preferably, the nozzles 44 are directed toward the first surface 31 of the evaporative heat exchange core 30, so that the spray liquid sprayed by the nozzles 44 can easily enter the inside of the evaporative heat exchange core 30 directly, thereby preventing the entry of the evaporative heat exchange core. The hot air inside 30 is cooled to improve the utilization rate of the spray liquid, thereby improving the cooling efficiency.
作为解释说明,如图2B所示,通过在喷臂42的至少一端设置至少一个旋转喷口421,可以通过旋转喷口421用于向外喷液时来驱动喷臂42旋转。根据牛顿第三定律中的作用力和反作用力的原理可知,当液体从狭小的空间向外喷射时(图中F为液体的喷射力方向),液体受到液压作用向前喷射,那么向前喷射的液体会给喷口处一个大小相等、方向相反的反作用力(图中用F'表示该反作用力),就像水枪在喷射液体时,水枪会受到一个后坐力一样。本申请中的液体从旋转喷口421喷出时也会给旋转喷口421一个大小相等方向相反的反作用力(图中用F'表示该反作用力),而设置有旋转喷口421的喷臂42与进液管41的出液口411旋转连接,所以当这个反作用力足够大时,就会驱动喷臂42绕着固定的支点也就是进液管41的出液口411转动(转动方向为图中虚线箭头所示的v方向)。As an explanation, as shown in FIG. 2B , by disposing at least one rotating nozzle 421 at at least one end of the spray arm 42 , the spray arm 42 can be driven to rotate when the rotating nozzle 421 is used to spray liquid outward. According to the principle of action force and reaction force in Newton's third law, when the liquid is sprayed outward from a narrow space (F in the figure is the direction of the liquid's spray force), the liquid is sprayed forward by the hydraulic action, then the forward spray The liquid will give an equal and opposite reaction force at the nozzle (the reaction force is represented by F' in the figure), just like the water gun will experience a recoil when it sprays liquid. When the liquid in this application is sprayed from the rotating nozzle 421, it will also give the rotating nozzle 421 an equal and opposite reaction force (the reaction force is represented by F' in the figure), and the spray arm 42 provided with the rotating nozzle 421 and the inlet The liquid outlet 411 of the liquid pipe 41 is connected in rotation, so when the reaction force is large enough, the spray arm 42 will be driven to rotate around the fixed fulcrum, that is, the liquid outlet 411 of the liquid inlet pipe 41 (the direction of rotation is the dotted line in the figure). v direction indicated by the arrow).
作为解释说明,当旋转喷口421中喷射液体时,根据作用力和反作用力的原理可知,喷射液向前的喷射力会给旋转喷口421一个方向相反的作用力,而这个方向相反的作用力足够大时,可以驱动喷臂42旋转。As an explanation, when liquid is sprayed in the rotating nozzle 421, according to the principle of action force and reaction force, the forward spray force of the spray liquid will give the rotating nozzle 421 a force in the opposite direction, and the force in the opposite direction is sufficient. When large, the spray arm 42 can be driven to rotate.
另外,需要说明的是,旋转喷口421的数量、设置位置以及设置的角度都会影响喷臂42旋转的速度,因此旋转喷口421的设置可以根据具体需要具体设置,其中最佳的角度是与喷臂42旋转轨迹的切线方向相同。In addition, it should be noted that the number of the rotating nozzles 421, the setting position and the setting angle will affect the rotation speed of the spraying arm 42. Therefore, the setting of the rotating nozzles 421 can be set according to specific needs. The best angle is the same as that of the spraying arm. 42 The tangent direction of the rotation trajectory is the same.
进一步的,如图2C-5所示,喷臂42的中部设有连接管43,喷臂42通过连接管43与进液管41转动相连,且连接管43与进液管41的出液口411连通。通过设置连接管43可以方便地将喷臂42和进液管41转动连接,从而顺利的将液体从进液管41通入到喷臂42中去。Further, as shown in FIG. 2C-5 , a connecting pipe 43 is provided in the middle of the spray arm 42 , and the spray arm 42 is rotatably connected to the liquid inlet pipe 41 through the connecting pipe 43 , and the connecting pipe 43 is connected to the liquid outlet of the liquid inlet pipe 41 . 411 Connected. By arranging the connecting pipe 43 , the spray arm 42 and the liquid inlet pipe 41 can be conveniently connected in rotation, so that the liquid can be smoothly passed from the liquid inlet pipe 41 to the spray arm 42 .
需要说明的是,连接管43的具体形状可以根据喷臂42的形状进行具体设计。例 如,连接管43可以为与喷臂42一体成型的结构,也可以为通过螺纹连接或者是焊接的方式固定在喷臂42上的结构,只要是能够与进液管41连接,并能够实现喷臂42和进液管41之间的连通即属于本申请技术方案的保护范围。It should be noted that the specific shape of the connecting pipe 43 can be specifically designed according to the shape of the spray arm 42 . For example, the connecting pipe 43 may be a structure integrally formed with the spray arm 42, or may be a structure fixed on the spray arm 42 by screwing or welding, as long as it can be connected with the liquid inlet pipe 41 and can realize spraying The communication between the arm 42 and the liquid inlet pipe 41 belongs to the protection scope of the technical solution of the present application.
进一步的,喷臂42的连接管43设有卡合部431,其中卡合部431与进液管41的出液端转动连接。Further, the connecting pipe 43 of the spray arm 42 is provided with an engaging portion 431 , wherein the engaging portion 431 is rotatably connected with the liquid outlet end of the liquid inlet pipe 41 .
进一步的,卡合部431包括固定部432;其中,固定部432与喷臂42相连且沿着远离喷臂42的方向延伸;固定部432靠近连接管43的一侧设置有卡合凸起433。Further, the engaging portion 431 includes a fixing portion 432; wherein, the fixing portion 432 is connected to the spray arm 42 and extends in a direction away from the spray arm 42; a side of the fixing portion 432 close to the connecting pipe 43 is provided with an engaging protrusion 433 .
进一步的,卡合凸起433朝向进液管41的出液口411的一面为锥面,锥面的大端朝向出液口411。Further, the surface of the engaging protrusion 433 facing the liquid outlet 411 of the liquid inlet pipe 41 is a tapered surface, and the large end of the tapered surface faces the liquid outlet 411 .
进一步的,连接管43的外壁套设有垫圈434,垫圈434位于卡合凸起433靠近喷臂42的一端。Further, a gasket 434 is sleeved on the outer wall of the connecting pipe 43 , and the gasket 434 is located at one end of the engaging protrusion 433 close to the spray arm 42 .
在本实施例中,通过将连接管43设计成具有卡合部431的结构,这样可以方便进液管41和喷臂42之间的安装;通过在卡合部431上设置固定部432,并通过在卡合不上设置凸起结构来实现与进液管41的连接,可以简化卡合部431的结构,降低生产成本;另外,通过将卡合凸起433设置成锥面可以方便安装和卡合,这样可以保证喷臂42和进液管41之间的连接稳定性;通过在连接管43的外壁套设有垫圈434,一方面可以保证连接稳定性,另一方面还可以保证喷臂42和进液管41之间的密封性。In this embodiment, by designing the connecting pipe 43 to have a structure with an engaging portion 431, the installation between the liquid inlet pipe 41 and the spray arm 42 can be facilitated; The connection with the liquid inlet pipe 41 is realized by arranging a protruding structure on the non-engaging portion, which can simplify the structure of the engaging portion 431 and reduce the production cost; This can ensure the connection stability between the spray arm 42 and the liquid inlet pipe 41; by setting the gasket 434 on the outer wall of the connecting pipe 43, the connection stability can be ensured on the one hand, and the spray arm can also be guaranteed on the other hand. The tightness between 42 and the liquid inlet pipe 41.
需要说明的是,本申请中的喷臂42和进液管41之间可以不绝对密封,因为喷淋设备就是通过喷液实现降温的,因此有些许漏液现象只会影响喷液的力度,但是对降温以及防水不会产生特别大的影响。It should be noted that the spray arm 42 and the liquid inlet pipe 41 in the present application may not be absolutely sealed, because the spray equipment achieves cooling by spraying liquid, so a little leakage phenomenon will only affect the strength of the liquid spray, But it will not have a particularly big impact on cooling and waterproofing.

需要说明的是,本实施例中的第一方向和第二方向均与子喷臂422旋转轨迹相切的方向相同。本实施例中,第一旋转喷口421a的喷射方向与第一方向相反,第二旋转喷口421b的喷射方向与第二方向相反,并且,第一方向和第二方向均与喷臂42端部的轴线垂直,这样可以使驱动喷臂42旋转的力最大,从而更加容易的驱动喷臂42旋转。It should be noted that both the first direction and the second direction in this embodiment are the same as the direction tangent to the rotation trajectory of the sub-spray arm 422 . In this embodiment, the spraying direction of the first rotating nozzle 421a is opposite to the first direction, the spraying direction of the second rotating nozzle 421b is opposite to the second direction, and both the first direction and the second direction are opposite to the end of the spray arm 42 .
