具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点,下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请,但是,本申请还可以采用其他不同于在此描述的其他方式来实施,因此,本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图17描述根据本申请一些实施例的燃气设备。
实施例一:
如图1至图3所示,燃气设备10自上而下依次设有换热器60、燃烧器500和风机30,其中,燃烧器500设于框体100内侧,风机30设于框体100外侧,换热器60可以设于框体100外或框体100内,换热器60也可以一部分设于框体100内,另一部分设于框体100外。
具体地,如图1至图3所示,框体100限定出腔室11,燃烧器500设在腔室11的下侧,风机30安装于框体100的外侧,风机30的出口与燃烧器500相对。即风机30启动时,空气将被送入腔室11内,与进入燃烧器500的燃气混合,形成待燃烧的空燃混合气体。空燃混合气体在燃烧器500内被点燃,产生的高温烟气进入腔室11的上侧,并流向换热器60,加热换热器60内的水。
为避免高温烟气的热量被传导出框体100外,对燃气设备10的零部件造成伤害,框体100的内侧还设有隔板200。隔板200与框体100的至少一部分内壁间隔设置,从而构设出风道50。例如,在框体100为方形框的情况下,隔板200与框体100的至少一个侧壁(左壁、右壁、前壁和后壁的至少之一)间隔设置。换言之,框体100绕设在隔板200的周向,从而通过框体100和隔板200构设出一个或多个沿周向分布的风道50。风道50在周向上可以形成一单腔风道,也可以在周向上形成多个相互的风道。
其中,风机30送出的空气,一部分流入风道50内,另一部分流入燃烧器500内。即空气一部分进入燃烧器500内参与燃烧,另一部分进入风道50内用于风冷框体100,避免框体100温度过高。
申请人经过多次试验发现,空气在风道50内流淌一段距离之后,空气温度将上升到较高温度,无法对框体100进行冷却,导致框体100局部冷却失效,在热传导的作用,必然导致框体100已经冷却的部分也再次被加热,最终无法实现对框体100冷却的目的。
在该实施例中,隔板200在风道50流动方向上设有多个出风孔52。这样,随着空气在风道50内的流动,逐级向腔室11内喷出多股空气流,从而在隔板200的内侧形成气膜,该气膜可以阻挡热空气向隔板200方向流动,从而避免风道50内的空气温升过高而无法风冷框体100。
简言之,根据本申请实施例的燃气设备10,通过在框体100与隔板200构设出用于风冷框体100的风道50,且隔板200在风道50流动方向上设有多个出风孔52,从而在隔板200的内侧形成阻挡热空气向隔板200方向流动的气膜,进而提高风道50内空气对框体100的风冷效果,有效避免高温向框体100外传导,提高燃气设备10的零部件的使用寿命。
框体100所限定出的腔室11为封闭的腔室11,框体100外侧设置有风机30,风机30向框体100内送入空气。
风机30设置于框体100的下方,风机30送入框体100内的空气由腔室11的下方向上运动,部分空气进入燃烧器,并与燃烧器内的燃气混合后在火排处燃烧;另一部分空气进入到风道50内,并在风道50内继续向上运动,然后由出风孔52流出,以在隔板200的内侧形成流动气膜。
实施例二:
如图1至图4所示,隔板200上形成多个转向部41,转向部41由内向外突出,出风孔52形成于转向部41上。参照图2中的风向指示箭头,气流沿着风道50从下往上流动,在遇到转向部41后,一部分气流被引向燃烧器500方向,即从转向部41设置的出风孔52流出。换言之,该转向部41对风道50内的气流起到截流的作用,使得一部分气流从出风孔52分流出去,从而在隔板200的内壁面形成气膜,阻挡热气流向框体100方向 流动。
可选实施例中,如图1至图4所示,转向部41包括:沿水平方向向外延伸的第一段411、一端与第一段411连接且沿竖直方向向上延伸的第二段412,一端与第二段412连接且在上下方向倾斜延伸的第三段413,出风孔52形成于第一段411上。由于该转向部41第一段411的阻挡,使得风道50的流通面积骤然减小,使得一部分气流可以从出风孔52流出,另一部分气流继续向上流动,并从另一个转向部41的出风孔52流出。此外,倾斜延伸的第三段413可以使得风道50的流通面积逐渐增大,使得气流更加顺畅地向上流动。
实施例三:
出风孔52为沿水平方向延伸的条形孔。条形的出风结构可以尽可能增大出风面,使得隔板200的整个周向内壁面均能形成气膜,阻挡热气流靠近框体100,进一步防止框体100温升过高。
可选示例中,出风孔52沿隔板的周向方向均匀分布,从而在隔板200的整个周向内壁面形成均匀的气膜,阻挡热气流靠近框体100,保证整个框体100的各个部分温度相差不多。
实施例四:
风道50的进风面积大于出风面积。即风道50下侧的总进风面大于隔板200上的出风孔52的总出风面,如此,可以保证具有足够空气量流向整个风道50,避免空气在流道风道50某个高度时,因空气量不足而无法继续向上流动,导致燃烧腔内热流逆流至风道50内。可选地,风道50的进风孔214环绕燃烧器500而设。
可选实施例中,风道50的进风面积与出风面积之比为5:2-4:3之间。为获得一个较佳的进风面积与出风面积之比,申请人做了大量实验,原因在于风机30提供的输入空气主要应用于燃烧器500的燃烧,在风机30的进风量不变的情况下,要将一部分空气输送至风道50内,必然会导致燃烧器500内的进风量减少,从而可能会影响到燃烧器500内的燃气是否能够充分燃烧,即是否会导致废气物排放超标的问题。因此,申请人综合考虑多方面因素的情况下,将风道50的进风面积与出风面积之比为5:2-4:3之 间,既可以保证风道50内具有足够的空气,又能保证燃气充分燃烧。
实施例五:
如图1至图3所示,风道50的进风面低于燃烧器500的燃烧面。这样,燃烧面产生的烟气经过隔板200的阻挡,可以被收拢在腔室11内,避免烟气作用于框体100上。
可选实施例中,如图1至图3所示,隔板的上部还设有中空凸柱42,中空凸柱42向框体100方向延伸,中空凸柱42的空腔构成出风孔52。该中空凸柱42可以迫使气流折弯之后,再向上流动,即在该风道50的上部形成一旋涡区,使得气流既可以到达风道50的顶部,又可以通过中空凸柱42流出风道50,从而保证风道50上部也能够实现风冷的同时,又可以在隔板200上形成气膜。
考虑到空气流到达风道50上部时,风压相对较小,因此,中空凸柱42与风道50顶面距离不能设置过长,过长可能导致气压不足以将气流推送至风道50顶部。优选地,中空凸柱42与风道50顶面距离为d,风道50的高度为h,d/h在1/20-1/10之间。如此,可以在隔板200的内壁面形成气压较好的气膜,也可以将空气送至风道50顶部,从而获得较佳的风冷效果,保证框体100温升在可控的范围内。
实施例六:
如图1至图3所示,燃气设备10自上而下依次设有换热器60、燃烧器500和风机30,其中,燃烧器500设于框体100内侧,风机30设于框体100外侧,换热器60可以设于框体100外或框体100内,换热器60也可以一部分设于框体100内,另一部分设于框体100外。
具体地,如图1至图3所示,框体100限定出腔室11,燃烧器500设在腔室11的下侧,风机30安装于框体100的外侧,风机30的出口与燃烧器500相对。即风机30启动时,空气将被送入腔室11内,与进入燃烧器500的燃气混合,形成待燃烧的空燃混合气体。空燃混合气体在燃烧器500内被点燃,产生的高温烟气进入腔室11的上侧,并流向换热器60,加热换热器60内水。
为避免高温烟气的热量被传导出框体100外,对燃气设备10的零部件 造成伤害,框体100的内侧还设有隔板200。隔板200与框体100的至少一部分内壁间隔设置,从而构设出风道50。例如,在框体100为方形框的情况下,隔板200与框体100的至少一个侧壁(左壁、右壁、前壁和后壁的至少之一)间隔设置。换言之,框体100绕设在隔板200的周向,从而通过框体100和隔板200构设出一个或多个沿周向分布的风道50。风道50在周向上可以形成一单腔风道,也可以在周向上形成多个相互的风道。
其中,风机30送出的空气,一部分流入风道50内,另一部分流入燃烧器500内。即空气一部分进入燃烧器500内参与燃烧,另一部分进入风道50内用于风冷框体100,避免框体100温度过高。
申请人经过多次试验发现,空气在风道50内流淌一段距离之后,空气温度将上升到较高温度,无法对框体100进行冷却,导致框体100局部冷却失效,在热传导的作用,必然导致框体100已经冷却的部分也再次被加热,最终无法实现对框体100冷却的目的。
在该实施例中,隔板200在风道50流动方向上设有多个出风孔52。这样,随着空气在风道50内的流动,逐级向腔室11内喷出多股空气流,从而在隔板200的内侧形成气膜,该气膜可以阻挡热空气向隔板200方向流动,从而避免风道50内的空气温升过高而无法风冷框体100。
简言之,根据本申请实施例的燃气设备10,通过在框体100与隔板200构设出用于风冷框体100的风道50,且隔板200在风道50流动方向上设有多个出风孔52,从而在隔板200的内侧形成阻挡热空气向隔板200方向流动的气膜,进而提高风道50内空气对框体100的风冷效果,有效避免高温向框体100外传导,提高燃气设备10的零部件的使用寿命。
实施例七:
如图1至图4所示,隔板200上形成多个转向部41,转向部41由内向外突出,出风孔52形成于转向部41上。参照图2中的风向指示箭头,气流沿着风道50从下往上流动,在遇到转向部41后,一部分气流被引向燃烧器500方向,即从转向部41设置的出风孔52流出。换言之,该转向部41对风道50内的气流起到截流的作用,使得一部分气流从出风孔52分流出去,从而在隔板200的内壁面形成气膜,阻挡热气流向框体100方向 流动。
可选实施例中,如图1至图4所示,转向部41包括:向框体侧壁方向延伸的第一段411、一端与第一段411连接且向上延伸的第二段412,出风孔52形成于第一段411上。由于该转向部41第一段411的阻挡,使得风道50的流通面积骤然减小,使得一部分气流可以从出风孔52流出,另一部分气流继续向上流动,并从另一个转向部41的出风孔52流出。此外,倾斜延伸的第三段413可以使得风道50的流通面积逐渐增大,使得气流更加顺畅地向上流动。
实施例八:
出风孔52为沿水平方向延伸的条形孔。条形的出风结构可以尽可能增大出风面,使得隔板200的整个周向内壁面均能形成气膜,阻挡热气流靠近框体100,进一步防止框体100温升过高。
可选示例中,出风孔52沿隔板的周向方向均匀分布,从而在隔板200的整个周向内壁面形成均匀的气膜,阻挡热气流靠近框体100,保证整个框体100的各个部分温度相差不多。
实施例九:
风道50的进风面积大于出风面积。即风道50下侧的总进风面大于隔板200上的出风孔52的总出风面,如此,可以保证具有足够空气量流向整个风道50,避免空气在流道风道50某个高度时,因空气量不足而无法继续向上流动,导致燃烧腔内热流逆流至风道50内。可选地,风道50的进风孔214环绕燃烧器500而设。
可选实施例中,风道50的进风面积与出风面积之比为5:2-4:3之间。为获得一个较佳的进风面积与出风面积之比,申请人做了大量实验,原因在于风机30提供的输入空气主要应用于燃烧器500的燃烧,在风机30的进风量不变的情况下,要将一部分空气输送至风道50内,必然会导致燃烧器500内的进风量减少,从而可能会影响到燃烧器500内的燃气是否能够充分燃烧,即是否会导致废气物排放超标的问题。因此,申请人综合考虑多方面因素的情况下,将风道50的进风面积与出风面积之比为5:2-4:3之间,既可以保证风道50内具有足够的空气,又能保证燃气充分燃烧。
实施例十:
如图1至图3所示,风道50的进风面低于燃烧器500的燃烧面。这样,燃烧面产生的烟气经过隔板200的阻挡,可以被收拢在腔室11内,避免烟气作用于框体100上。
可选实施例中,如图1至图3所示,隔板的上部还设有中空凸柱42,中空凸柱42向框体100方向延伸,中空凸柱42的空腔构成出风孔52。该中空凸柱42可以迫使气流折弯之后,再向上流动,即在该风道50的上部形成一旋涡区,使得气流既可以到达风道50的顶部,又可以通过中空凸柱42流出风道50,从而保证风道50上部也能够实现风冷的同时,又可以在隔板200上形成气膜。
考虑到空气流到达风道50上部时,风压相对较小,因此,中空凸柱42与风道50顶面距离不能设置过长,过长可能导致气压不足以将气流推送至风道50顶部。优选地,中空凸柱42与风道50顶面距离为d,风道50的高度为h,d/h在1/20-1/10之间。如此,可以在隔板200的内壁面形成气压较好的气膜,也可以将空气送至风道50顶部,从而获得较佳的风冷效果,保证框体100温升在可控的范围内。
实施例十一:
隔板与框体的侧壁相连接,隔板包括:与框体侧壁倾斜设置的隔热部,隔热部远离框体侧壁的一端向外折弯以形成转向部,和/或隔热部靠近框体侧壁的一端向内折弯以形成转向部。
