- a ventilation structure 100 provided in one embodiment of the present application includes a mounting body 10 and at least one set of flow guide assemblies 3.
- the mounting body 10 is configured to be assembled and connected to the vent 210 of the energy storage cabinet 200. All flow guide assemblies 3 are connected to the mounting body 10.
- Each set of flow guide assemblies 3 includes a plurality of flow guide members 30 arranged along a first direction (the X direction as shown in Figure 5 ), which intersects the ventilation direction of the energy storage cabinet 200 (the Y direction as shown in Figure 5 ).
- the flow guide members 30 have a concave cavity 31 with an opening formed on one side facing the ventilation direction.
- the ventilation structure 100 is installed at the vent 210 via the mounting body 10. After installation, the ventilation structure 100 blocks the vent 210 or is partially embedded in the vent 210, so that ventilation at the vent 210 is carried out through the ventilation structure 100. All the guide members 30 are connected to the mounting body 10 and are uniformly installed at the vent 210 of the energy storage cabinet 200 via the ventilation structure 100. The airflow passing through the vent 210 must be guided by the guide assembly 3.
- vent 210 of the energy storage cabinet 200 can be either an air inlet 211 or an air outlet 212.
- the air guide assembly 3 does not completely block the vent 210, but only guides the airflow flowing through the vent 210 or changes its flow direction and state.
- each guide member 30 has a windward side and a leeward side on either side in the ventilation direction.
- the windward side of the guide member 30 has a diversion function, and the wind resistance of the guide member 30 on the windward side is lower, allowing it to guide the airflow.
- the guide member 30 forms the aforementioned cavity 31, which has greater wind resistance and can absorb and eliminate noise.
- the drag coefficients of the guide member 30 on the windward and leeward sides are configured to be different. Under the same conditions, the wind resistance generated by airflow blowing toward the windward and leeward sides of the guide member 30 is different.
- the drag coefficient on the leeward side may be no less than 0.8, and may specifically be 0.8, 0.9 or 1, etc.

- the ventilation structure 100 is attached to the vent 210. Airflow passing through the vent 210 also flows through the ventilation structure 100. As noise propagates outward through the ventilation structure 100, it collides and dissipates between the guide members 30, achieving a noise reduction effect.
- the ventilation structure 100 can be strategically positioned so that the cavity 31 of the guide member 30 faces the interior of the energy storage cabinet 200, that is, toward the noise source. Airflow flowing in from the outside is properly guided by the guide member 30 and smoothly enters the interior, while noise propagating from the inside out is absorbed and dissipated by the cavity 31 of the guide member 30. In this way, the ventilation structure 100 integrates noise reduction functionality, providing both air guidance and noise reduction. This makes the ventilation structure 100 simple and highly integrated, making it easy to attach to the vent 210, ensuring ventilation and heat dissipation while suppressing noise transmission.
- the ventilation structure 100 further includes a silencer 70 (as shown in FIG. 12 and FIG. 15 ).
- the silencer 70 is disposed on a side of the guide member 30 facing the interior of the energy storage cabinet 200 in the ventilation direction.
- the silencer 70 may be made of, but is not limited to, silencer cotton, sponge, velvet, or the like.
- the flow guide 30 is covered with the silencer 70 on the side facing the interior of the energy storage cabinet 200 , that is, the side facing the noise source, so that when the noise propagates to the surface of the flow guide 30 , it is silenced by the silencer 70 .
- At least a portion of the edge of the flow guide 30 is configured as a circular arc transition.
- the smooth design of the guide member 30 can effectively reduce the wind resistance of the ventilation airflow and ensure normal heat dissipation.
- the ventilation structure 100 includes at least three groups of guide components 3 , all of which are sequentially arranged at intervals along the ventilation direction, and the guide members 30 of two adjacent groups of guide components 3 are staggered.
- the longitudinal directions of all the guide members 30 are parallel to each other, and the ventilation direction, the first direction and the longitudinal directions of the guide members 30 intersect with each other.
- the following embodiments are explained by taking the ventilation direction, the first direction and the longitudinal directions of the guide members 30 as an example in which they are perpendicular to each other.
- the staggered arrangement of the guide members 30 of two adjacent groups of guide assemblies 3 means that the guide members 30 of the two adjacent groups of guide assemblies 3 are alternately arranged in the first direction. Overall, each group of guide assemblies 3 forms a layer of noise reduction structure, and all the guide members 30 are staggered to form a multi-layer noise reduction structure.
- all the guide members 30 are arranged and combined in a staggered manner to form a multi-layer noise reduction structure.
- the noise passes through the multi-layer noise reduction and can be emitted between the guide components 3 on different layers to be consumed and absorbed.
- the mounting body 10 includes a top plate 11 and a bottom plate 13 extending along a first direction, all the guide components 3 are located between the top plate 11 and the bottom plate 13, and opposite ends of each guide member 30 are connected to the top plate 11 and the bottom plate 13 respectively.

- the mounting body 10 further includes two side panels 15 .

- the mounting body 10 has a stable structure and serves as a frame, and its internal space is just right for arranging the guide assembly 3.
- the ventilation structure 100 can be fixed to the ventilation opening 210 by screw connection, welding, clamping, bonding, etc. through the flange 17, and the fixing method can be detachable.
- the mounting body 10 is generally a rectangular frame formed by sequentially connecting a top plate 11 , a side plate 15 , a bottom plate 13 , and another side plate 15 end to end.
- the mounting body 10 may also be a circular frame, a triangular frame, etc., as long as it can adapt to the shape of the vent 210, and is not specifically limited here.
- At least part of the flow guide assembly 3 further includes an arcuate flow guide 50, which is provided on the side plate 15.

Description

本申请涉及储能技术领域,具体涉及通风结构、储能柜以及储能系统。
当前市场上储能液冷户外柜中散热设备因功能需求需要与舱外环境进行通风环流、冷却散热,从而能保证器件正常运行。
然而,设备在运行过程中,内部扰流散热风扇等设备的运行会产生噪声,对外部环境造成影响。
发明内容
基于此,有必要针对上述的问题,提供一种能够在实现通风散热的同时,抑制噪声向外传递的通风结构、储能柜以及储能系统。
一种通风结构,用于储能柜,所述通风结构包括:

在其中一个实施例中,所述通风结构还包括消音件,所述消音件覆设于所述导流件在所述通风方向上朝向所述储能柜内部的一侧上。
在其中一个实施例中,所述通风结构包括至少三组所述导流组件,全部所述导流组件沿所述通风方向顺次间隔布置,且相邻的两组所述导流组件的所述导流件错位排布。
在其中一个实施例中,所述安装体包括沿所述第一方向延伸的顶板和底板,全部所述导流组件位于所述顶板与所述底板之间,每一所述导流件相对的两端分别连接所述顶板和所述底板。
在其中一个实施例中,所述安装体包括还包括两个侧板,所述两个侧板与所述顶板和所述底板共同形成一框架,并向四周形成翻边。
在其中一个实施例中,至少部分所述导流组件的还包括弧形导流件,所述弧形导流件设于所述侧板上。
在其中一个实施例中,每组所述导流组件的至少部分所述导流件相互间隔;沿所述通风方向在垂直于所述通风方向的平面上的投影,全部所述导流件共同覆盖所述通风口。
在其中一个实施例中,所述导流件的纵长方向与所述通风方向相交,所述导流件垂直于其纵长方向的横截面为Y形结构,且所述Y形结构的上下方向与所述通风方向平行。
一种储能柜,所述储能柜包括柜体及上述的通风结构。
在其中一个实施例中,所述柜体的柜门、顶板以及底板中至少一者形成有通风口,且至少部分所述通风口设有所述通风结构。
在其中一个实施例中,所述柜门上形成有所述通风口,并作为进风口,所述进风口设有所述通风结构,且所述导流件的所述凹腔的开口朝向所述柜体内部;所述通风结构还包括消音件,所述消音件覆设于所述凹腔的腔壁上。

此外,若有出现术语“和/或”,“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。若有出现这些术语“第一”、“第二”,这些术语仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中,若有出现术语“多个”,“多个”的含义是至少两个,例如两个,三个等,除非另有明确具体的限定。
在本申请中,除非另有明确的规定和限定,若有出现术语“安装”、“相连”、“连接”、“固定”等,这些术语应做广义理解。例如,可以

请参阅图1至图8,本申请一实施例提供的通风结构100,包括安装体10及至少一组导流组件3。安装体10用于与储能柜200的通风口210装配连接。全部导流组件3连接在安装体10上,每组导流组件3包括沿第一方向(如图5所示X方向)排列设置的多个导流件30,第一方向与储能柜200的通风方向(如图5所示Y方向)相交。导流件30在通风方向上的一侧形成具有开口的凹腔31。
可以理解地,通风结构100通过安装体10安装在通风口210处,安装后的通风结构100遮挡在通风口210上或部分嵌套于通风口210,使通风口210处的通风通过通风结构100进行。全部导流件30连接在安装体10上,并统一通过通风结构100安装在储能柜200的通风口210处,经过通风口210的气流需经导流组件3导流。
可以理解地,储能柜200的通风口210既可以是进风口211,也可以是出风口212。为实现通风的基本功能,导流组件3并不会完全封堵通风口210,而仅仅发挥对通风口210处流动的气流产生引导或改变其流动方向、状态的作用。
具体而言,每个导流件30在通风方向上的两侧分别为迎风侧和背风侧。导流件30的迎风侧具有导流功能,导流件30在迎风侧风阻较低,能够引导气流流动。而在背风侧,导流件30形成上述凹腔31,风阻较大,能够通过凹腔31吸收、消弭噪声。换言之,导流件30在迎风侧和背风侧的阻力系数被配置为相异。在同种条件下,气流吹向导流件30的迎风侧和背风侧所产生的风阻不同。
其中,背风侧的风阻系数可不小于0.8,并具体可为0.8、0.9或1等,迎风侧的风阻系数可不大于0.5,并具体可为0.5、0.4、0.3、0.2或0.1等,在此不作具体限定。
在一具体实施例中,通风结构100用于储能柜200或储能系统400的舱体410上等,用于消弭储能柜200内设备的运行噪声或储能系统400中位于舱室内设备的运行噪声。
上述通风结构100,将其附加在通风口210处,通过通风口210流通的气流同样会流经通风结构100。其中,噪声在通过通风结构100向外传递时,会在导流件30之间碰撞、消弭,到达降噪的效果。当通风口210为进风口211时,可合理布置通风结构100,使其导流件30的凹腔31开口朝向储能柜200的内部,也就是朝向噪声源。由外向内吹入的气流受到导流件30的正常引导,顺利的吹入内部,而由内向外传递的噪声则会被导流件30的凹腔31吸收、消弭。如此,通风结构100集成有降噪功能,既能导流又能降噪,使通风结构100拥有简单的结构且集成度高,便于附加在通风口210上,以在实现满足通风散热的同时,抑制噪声向外传递。
在一些实施例中,通风结构100还包括消音件70(如图12及图15所示),消音件70覆设于导流件30在通风方向上朝向储能柜200内部的一侧上。
消音件70可以为但不限于为消音棉、海绵、绒等材质,导流件30在朝向储能柜200内部,也就是朝向噪声源的一侧覆设消音件70,以在噪声传播至导流件30表面时,被消音件70消音。
可以理解地,对于设于进风口211的通风结构100,其可配置为导流件30的凹腔31开口朝向储能柜200内部,故消音件70覆设在凹腔31的腔壁上。对于设于出风口212的通风结构100,其可配置为导流件30的凹腔31开口背向储能柜200内部,故其朝向储能柜200内部的表面覆设消音件70。
如此,在表面消音件70的帮助下,能够更高效低吸收、消弭噪声,提高降噪效果。
在一些实施例中,导流件30的至少部分边缘构造为圆弧过渡。
如此,导流件30的圆滑设计,可以有效降低通风气流的风阻,保证散热的正常进行。
在一些实施例中,通风结构100包括至少三组导流组件3,全部导流组件3沿所述通风方向顺次间隔布置,且相邻的两组导流组件3的导流件30错位排布。
可以理解地,全部导流件30的纵长方向(对应于图5中垂直于纸面的方向)相互平行,通风方向、第一方向以及导流件30的纵长方向之间两两相交,为便于理解,下述实施例中以通风方向、第一方向以及导流件30的纵长方向两两相互垂直为例进行说明。
相邻的两组导流组件3的导流件30错位排布指的是,相邻的两组导流组件3的导流件30在第一方向交替设置。整体上来看,每组导流组件3形成为一层降噪结构,全部导流件30错落排布形成多层降噪结构。
如此,全部导流件30错落排布组合,形成多层降噪结构,噪声在传播的过程中,经过多层降噪,并能够在不同层的导流组件3之间进行发射,而被消耗、吸收。
在一些实施例中,安装体10包括沿第一方向延伸的顶板11和底板13,全部导流组件3位于顶板11与底板13之间,每一导流件30相对的两端分别连接顶板11和底板13。
换言之,每组导流组件3的导流件30的排列方向与顶板11和底板13的延伸方向一致。顶板11和底板13分别位于导流件30在纵长方向上的相对两端。导流件30可被配置为沿高度方向设置,顶板11和底板13则分别位于上下两侧。
如此,全部导流件30能够被顶板11和底板13稳定固定,被最终通过安装体10稳定安装于储能柜200的通风口210处。
进一步地,安装体10包括还包括两个侧板15,两个侧板15与顶板11和底板13共同形成一框架,且所述框架四周形成翻边17。
如此,安装体10结构稳定,作为框架,其内部空间正好用来布置导流组件3。此外,通风结构100能够通过翻边17利用螺钉连接、焊接、卡接、粘接等方式将其固定在通风口210处,且该固定方式可为可拆卸固定。
在一具体实施例中,安装体10大体为有顶板11、侧板15、底板13以及另一侧板15首尾顺次连接形成的矩形框架。
可以理解地,在其它实施例中,安装体10还可以为圆形框架、三角形框架等,只需能够适应通风口210的形状即可,在此不作具体限定。
在一些实施例中,至少部分导流组件3的还包括弧形导流件50,弧形导流件50设于侧板15上。弧形导流件50的纵长方向与其它导流件30的纵长方向平行。
可以理解地,弧形导流件50上也可覆设有消音件70。同理地,弧形导流件50的消音件70同样覆设于其朝向噪声源的一侧。
在一些实施例中,每组导流组件3的至少部分导流件30相互间隔。沿通风方向在垂直于通风方向的平面上的投影,全部导流件30共同覆盖通风口210。可以理解地,此处全部导流件30可包括导流件30和弧形导流件50。
换言之,光线无法沿通风方向自通风结构100的一侧穿过通风结构100达通风结构100的另一侧。
可以理解地,全部导流件30可相互间隔设置,并通过错落设置的方式,在彼此相互间隔的同时,实现沿通风方向在垂直于通风方向的平面上的投影相互重叠,并覆盖整个通风口210。具体来讲,全部导流件30可配置为沿任意方向的投影,均共同覆盖通风口210。
如此,在通风方向的角度,全部导流件30共同覆盖通风口210,能够提高噪声穿透的难度,使噪声在不同的导流件30之间反射,增强降噪效果。此外,在通风方向的角度,全部导流件30共同覆盖通风口210还能够提高其防水性能,满足设备防水需要。
在一具体实施例中,通风结构100包括三组导流组件3,分别为位于通风方向上顺次布置的第一排、第二排以及第三排。其中,沿通风方向在垂直于通风方向的平面上的投影,第一排和第三排的导流组件3相互重合,第二排导流组件3中每个导流件30位于第一排或第三排导流组件3中两个导流件30之间。在第一方向上,第一排或第三排的导流组件3的导流件30与第二排的导流组件3的导流件30的投影交替连接。两个弧形导流件50则与第二排导流组件3的导流件30并排设置,且沿通风方向在垂直于通风方向的平面上的投影,两个弧形导流件50分别与第一排的导流组件3或第三排的导流组件3的导流件30连接。
在一些实施例中,导流件30在通风方向上一侧(即对应背风侧)形成凹腔31,在通风方向上相对的另一侧(即对应迎风侧)形成凸面,且凸面至少部分在第一方向上的宽度,沿背离凹面的方向上渐窄设置。
可以理解地,背风侧可沿通风方向向内凹形成凹腔31,迎风侧可沿通风方向向外凸形成凸面,且在背离背风侧的方向上渐窄设置。
如此,在迎风角度下,导流件30在通风方向上的两侧可以表现出显著的差异,背风侧的阻力系数可明显高于迎风侧。此外,当背风侧朝向噪声源时,凹腔31可更好地吸收噪声。
在其它一些实施例中,背风侧还可构造为垂直于通风方向的平面等,只需形成的阻力系数大于迎风侧即可,在此不作具体限定。
在一些实施例中,导流件30的纵长方向与通风方向相交,导流件30垂直于其纵长方向的横截面为Y形结构,且Y形结构的上下方向与通风方向平行。
Y形结构的上下方向对应于通风方向,其上侧内凹,即对应具有凹腔31的背风侧,其左右两侧与底侧即对应迎风侧。其中,Y形结构的左右两
侧可形成为弧形,在通风方向上的渐宽设置,Y形结构的上端边缘经弧形过渡后沿通风方向延伸形成导流段35,以降低导流风阻。
如此,导流件30的凹腔31开口对应Y形结构内凹的叉口,具有较大的阻力系数,并具有良好的消音性能。同时,导流件30的迎风侧则主要对应Y形结构的左右两侧,在通风方向上的渐宽设置可以有效降低阻力系数,便于通风散热。
上述通风结构100,其导流件30和弧形导流件50有序的错落排布组合形成多层降噪结构,导流件30和弧形导流件50在朝向内部噪声源的表面还覆设有消音件70,且全部导流件30之间形成有间隙,保留通风口210的透气性能。此外,导流件30圆滑设计可有效降低风阻。如此,通风结构100能够供散热气流通过,以满足散热需求。同时,噪声在通风口210内向外传递时,受到多层降噪结构的阻挡,并能够在不同的导流件30之间反射,并逐渐被吸收、消弭,达到满足散热的同时,实现降噪的效果。
其中,对于设于进风口211处的通风结构100,其内导流件30具有凹腔31的一侧朝向进风口211内,另一侧朝向进风口211外。在工作时,散热气流由外向内流动,而噪声则是由内向外传播,两者路径相反。散热气流吹向具有导流作用的迎风侧,阻力较小,并在导流件30的引导下,吹向进风口211内,进行散热。而噪声在传播过程中,在导流件30的凹腔31和贴附在凹腔31腔壁上的消音件70的作用下被吸收、消弭,并依次受到多层降噪结构的多段降噪,逐渐降低,从而达到降噪的目的。
对于设于出风口212处的通风结构100,其内导流件30的形成凹腔31的一侧朝向出风口212外,另一侧朝向出风口212内。在工作时,散热气流换热后由内向外流动,流吹向具有导流作用的迎风侧,受到较小的阻力,并在导流件30的引导下,吹出风口212外。噪声在传播过程中,在导流件30表面之间和贴附在导流件30表面上的消音件70的作用下被吸收、消弭,并依次受到多层降噪结构的多段降噪,逐渐降低,从而达到降噪的目的。
本申请还提供了一种储能柜200,储能柜200包括柜体21及上述的通风结构100。
进一步地,所述柜体21的柜门213、顶板11以及底板13中至少一者形成有通风口210,且至少部分通风口210设有通风结构100。
如此,通风口210及安装在通风口210处的通风结构100能够便于通风,且不占用过多的柜体21内部空间。
更进一步地,柜门213上形成有通风口210,并作为进风口211,进风口211设有通风结构100,且导流件30的凹腔31的开口朝向柜体21内部。消音件70覆设于凹腔31的腔壁上。
可以理解地,进风口211的通风结构100可安装于柜门213的内侧,出风口212可形成于柜体21的顶部,出风口212的通风结构100可安装于柜体21的顶部。
如此,既不会影响到门的开合角度,又不影响储能柜200的整体外观。
请参阅图9至图16,本申请还提供了一种储能系统400,包括上述的通风结构100或上述的储能柜200。
此外,为实现其正常功能,储能系统400还包括电池系统、液冷机组412、电气系统中至少一者。储能系统400还包括舱体410,舱体410形成有液冷舱411、电池舱、电气舱等,液冷机组412安装于液冷舱411内、电池系统安装于电池舱内,电气系统安装于电气舱内。其中,舱体410可使用上述储能柜200充当。
储能系统400各舱室内的设备在运行过程中会产生热量,同时也会产生一定程度的噪声,当室外空气进入进出舱室为设备散热时,噪声如果通过进风口211、出风口212等通风口210传播到室外对外界造成影响。
以液冷舱411为例,舱室防护等级设计为IP20,为满足液冷舱411的散热需求,采用正面进风顶部出风的方式。在液冷舱411的进风口211和出风口212均设置通风结构100,既能满足通风环流、设备散热冷却,又可以降低舱室传播到室外的噪声,从而达到整个储能系统400的降噪功能。
