Description

散热装置及其风扇装置、风扇
技术领域
本发明涉及一种散热装置,特别是指一种风扇及采用该风扇的散热装置。
背景技术
目前,在电子元件散热领域,经常采用风扇与散热器组合而成的散热装置对发热电子元件散热,如中国专利公告第CN2455044Y号所示的散热装置,该散热装置包括一散热体及一风扇,该散热体安装在一发热电子元件上方用于吸收散发该电子元件上的热量,该风扇安装在该散热体一侧用于对该散热体吹风散热。该风扇从其转子的轮毂一侧吸入气流,然后朝该轮毂的另一侧,即该散热体所在侧,吹出气流。该风扇内设置有由磁铁、铁心及线圈组成的驱动结构,导致该轮毂的体积较大,使得从该轮毂一侧吸入的气流受到限制,影响了该风扇的散热效果。
发明内容
有鉴于此,有必要提供一种能提供较大风量的风扇、风扇装置及使用该风扇的散热装置。
一种散热装置,包括至少一散热器及至少一风扇,该风扇安装于该散热器上,该风扇包括一扇框及一收容于该扇框内的叶轮,该叶轮用于向该散热器吹风,该扇框外设置一马达,该马达通过一皮带轮传动机构与该叶轮的转动轴连接,该叶轮在该马达的带动下转动。
一种风扇,包括一扇框及一收容于该扇框内的叶轮,该扇框外安装一马达,该马达通过一皮带轮传动机构与该叶轮的转动轴连接,该叶轮在该马达的带动下转动。
一种风扇装置,包括一风扇及一固定架,该风扇包括一扇框及一收容于该扇框内的叶轮,该风扇安装在该固定架上,该扇框外安装一马达,该马达通过一皮带轮传动机构与该叶轮的转动轴连接,该叶轮在该马达的带动下转动。
所述散热装置通过该皮带轮传动机构驱动该风扇的叶轮转动,因此,该风扇的扇框内无需设置磁铁,该风扇的叶轮中无需设置铁心与线圈等结构而大大减少了体积,可增大从该叶轮一侧吸入的风量,提高该散热装置的散热能力。

所述散热器10包括若干散热鳍片12、两根热管14及一导热板16。该导热板16位于该散热器10的底部用于与发热电子元件接触,该导热板16大致呈方形,该导热板16的顶部开设有两条凹槽(图未标)用于收容热管14,该导热板16的四角上穿设有四螺钉18,该四螺钉18用于将该导热板16固定在该发热电子元件所在的电路板(图未示)上。
所述散热鳍片12位于该导热板16的上方,这些散热鳍片12的中部开设有二通孔(图未标)用于收容热管16。这些散热鳍片12的顶部开设有一狭长凹槽15,该凹槽15邻近这些鳍片12顶部的一边缘,并且该凹槽15沿与该边缘平行的方向贯穿鳍片12的顶部。
所述热管14弯折成U形,每一热管14的两端分别贯穿收容于导热板16的顶部凹槽及散热鳍片12的中部通孔中,该热管14用于将导热板16上的热量迅速传导至散热鳍片12上。
所述固定架30大致为方形框架,该固定架30包括一水平顶边32及两竖直侧边36,该顶边32位于该固定架30的顶部,该两侧边36分别自该顶边32的纵向两端向下延伸。该顶边32的横向一端向下延伸出一卡扣片321。每一侧边36的下端开设有一通孔361。自该两侧边36的边缘向该固定架30的内侧延伸出两固定片37,每一固定片37的内侧呈圆弧状,每一固定片37的上下两端分别开设有两通孔371。该两个固定片37的顶部抵靠在该顶边32上与卡扣片321相对的一端边缘。
所述马达20可通过焊接或粘接固定于该固定架30的顶边32上,该马达20的轴向一侧延伸出一皮带轮24,该皮带轮24位于与固定片37相同的一侧。
所述风扇50包括一方形扇框52,所述叶轮55收容于该扇框52中。该叶轮55包括一轮毂551及若干自该轮毂551外围向外延伸而出的扇叶554。该轮毂551内包括一转动轴552,该转动轴552与该轮毂551紧固连接从而该转动轴552与该轮毂551可同步转动,该轮毂551内未设磁铁和线圈因而具有较小的体积。该扇框52包括一“十”字形支架521,该支架521位于与固定架30相邻的一侧,该支架521的中央包括一轴套(图未标),该转动轴552枢接于该轴套中并贯穿通过该轴套,并且一皮带轮524连接于该转动轴552的末端,该皮带轮524可在该转动轴552的带动下同步转动。该皮带轮524与皮带轮24具有相同的结构,所述皮带40分别挂靠在该皮带轮524与皮带轮24上。扇框52的四角各设有一安装孔523。
在其它的实施例中,所述马达20还可安装在该散热器10上或者风扇的扇框52上。该固定架30与该风扇50可组成一风扇装置用于对其他发热源散热。
组装时,该固定架30安装于在该散热器10的一侧,其中该固定架30的卡扣片321卡扣于凹槽15内,顶边32抵靠在散热鳍片12的顶面,侧边36抵靠在散热鳍片12的两侧面,且该侧边36的底端抵靠在该导热板16的侧面,螺钉72通过该侧边36的通孔361并锁固在该导热板16上。四螺钉70贯穿扇框52的安装孔523并锁固在固定架30的通孔371内,从而将该风扇50固定在该固定架30一侧,且该马达20的皮带轮24通过皮带40与皮带轮524连接,从而驱动该叶轮55转动。因此,该风扇50的扇框52内无需设置磁铁,该风扇50的叶轮55中无需设置铁心与线圈等结构而大大减少了体积,可增大从该叶轮55一侧吸入的风量,提高该风扇50的散热能力。而且,由于该轮毂551内省去了磁铁、线圈等结构,可提高该轮毂551转动的平衡性,减少因叶轮55振动引起的噪声。
请参照图4至图6,为本发明第二实施例的散热装置200。该散热装置200包括两个散热器10a、10b,两个固定架30a、30b及两个风扇50a、50b,其中,该第一散热器10a、第一固定架30a及第一风扇50a组装在一起,该第二散热器10b、第二固定架30b及第二风扇50b组装在一起,该第一散热器10a与第二散热器10b相互间隔。该第一散热器10a、第一固定架30a及第一风扇50a与前述第一实施例中的散热装置100具有相似的结构,不同之处在于:该皮带轮524a具有两个轮槽526a、528a,其中一轮槽526a通过一竖直皮带40a与该第一固定架30a上的马达20a相连。该第二散热器10b、第二固定架30b及第二风扇50b与前述第一实施例中的散热装置100具有相似的结构,不同之处在于:该第二固定架30b上未设置马达,一横向皮带40b分别与皮带轮524a的轮槽528a、第二风扇50b的皮带轮524b相连,使得马达20a在通过皮带40a带动皮带轮524a转动的同时,进而通过皮带40b带动皮带轮524b转动,从而驱动风扇50a、50b的叶轮转动。
请参照图7及图8,所示为本发明第三实施例的散热装置300,该散热装置300包括一散热
