Description

组合式散热器
技术领域
本实用新型涉及散热器,尤指一种由冲压形成卡扣槽形片体一端与散热片相连接,各片体自由端与折片呈断离状态,并与相应卡扣片相抵扣,各片体除可加强前后散热片的紧密固接效果外,更可增加散热面积的组合式散热器。
背景技术
请参照图1、图1A所示,一般习知组合式的散热器,该散热器90由数个散热片100组成,各散热片100两边分别设有向内弯折呈90度的折片110,各折片110与散热片100连接处分别设有矩形的开口101,而各折片110在与开口101相对的端缘上则分别设有一向外延伸的卡扣片102,各卡扣片102设有内凹的弯折部103,组装时,将一散热片100的折片110的卡扣片102卡扣在另一散热片100的折片110的开口101中,如此重复上述动作,即可组成该种习知组合式的散热器。
该种习知组合式的散热器在使用时,虽可藉各散热片100的折片110的卡扣片102卡扣在另一散热片100的折片110的开口101中,组成一散热器90,但因该开口101与卡扣片102间仍有空隙,传导热时,会造成间断的情况发生。
请参照图2、图2A所示,另一习知组合式的散热器,由数个散热片200组合而成,各散热片200两边分别设有向内弯折呈90度的折片210,且各散热片200与折片210连接处设有与之平行的嵌槽201,再者,各折片210自由端设有一向外延伸的卡扣体220,各卡扣体220设有内缩的颈部221,各颈部221另一端设有向外扩张的弧曲部222,该种习知组合式的散热器虽可使卡扣体220与嵌槽201互相卡扣在一起,但为使各嵌槽201恰可卡扣于相应卡扣体220,通常是在各折片210上冲压出完整冲孔以形成嵌槽201,如此将使各散热片200的散热面积减少,再者,各卡扣体220与嵌槽201间的卡扣,是利用两者侧边的厚度相互抵扣,但因考虑各散热片200材料成本及体积的限制,各散热片200的厚度较薄,因此组装时,前后散热片间容易产生顷斜,甚至造成脱落的情况(如图2中a、b、c所示)。
发明内容
本实用新型的主要目的,在于提供一种由数个散热片组合而成,各散热片一端分别设有向内弯折呈90度的折片,各折片在与散热片相连接处分别设有向外延伸的卡扣槽,各卡扣槽设有由冲压形成的卡扣槽形的片体,各片体一端与散热片相连接,各片体的自由端与折片呈断开状态,各折片在与卡扣槽相对端缘上分别设有一卡扣片,各卡扣片在与折片连接端上设有向内缩合的对称颈部的组合式散热器。
组装时,将一散热片的卡扣片卡扣在另一散热片的卡扣槽中,同时使各卡扣片的颈部嵌合在相应卡扣槽中,不断重复上述动作,即可组成一组合式散热器。由于各片体的自由端与相应卡扣片相互抵扣,因此,各片体可增加抵压卡扣散热片的力量,除可加强前后散热片的紧密固接效果外,更可增加散热面积。
