技术领域

背景技术

1.虽然制造工艺的成熟可以降低漏液率,但是还是存在一定比例的漏液风险,漏液就会导致电脑硬件烧毁。
2.由于***内部长时间处于高压状态,密封圈等部件也会长时间处于疲劳状态。漏液的概率随着时间推移会逐渐变大。
3.单纯通过加强密封会带来***冗杂和成本上升。也会对设计和制造带来诸多限制。

具体实施方式
下面结合附图,对本发明的具体实施方式进行详细描述,但应当理解本发明的保护范围并不受具体实施方式的限制。
除非另有其它明确表示,否则在整个说明书和权利要求书中,术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分,而并未排除其它元件或其它组成部分。
实施例1
如图8所示,根据本发明具体实施方式的一种用于水冷散热器的收缩器,包括水腔壳体2以及至少一个收缩囊4,该水腔壳体2的内腔用来与水冷散热器的冷却水连通(参见图7),收缩囊4内置在水腔壳体2内,收缩囊4通过通气孔51与外界大气连通。
上述方案中,通过设置水腔壳体2与水冷散热器的冷却水连通,水腔壳体2的内腔成为水冷散热器的冷却水流通区域,然后在水腔壳体2内置收缩囊4,收缩囊4一般由弹性材料制成,通过收缩囊内径和长度大小调节容积大小,事先占用冷却水流通区域的一部分空间,当冷却水温度升高气压增大时,可以通过挤压收缩囊4泄压,收缩囊4的容积随着整个水冷***压力在动态调节,温度上升压力增大时容积被压缩,温度下降压力减小时容积恢复(参见图2和图3),而收缩囊4通过通气孔51与水腔壳体2的外侧连通,一般与大气相通,也即水腔壳体2内的压强通过收缩囊4的体积变化时刻和大气压相同,从根本上解决高压漏液的问题。
作为一种优选实施例,参见图8,水腔壳体2的侧壁上插设有套管3,收缩囊4的一端为开口端,开口端具有密封凸缘,收缩囊4穿过套管3内置在水腔壳体2内,套管3的尾部拧设有密封螺母5,密封凸缘抵接在套管3的尾部的端面上靠密封螺母5拧紧密封,通气孔51设置在密封螺母5的端面上(参见图4)。本方案中,密封螺母5的密封部分采用细牙螺纹配合,利于螺纹的自锁,防松动拧,紧密封螺母5使收缩囊4的端部与套管3的尾部稳固密封,从而保证冷液***露。
作为一种优选实施例,水腔壳体2呈圆筒形(参见图6),套管3插设在水腔壳体2一端的侧壁上。
作为一种优选实施例,收缩囊4呈长套形,收缩囊4穿过套管3后沿水腔壳体2的长度方向延伸。本方案中,收缩囊4可以采用柔软富有弹性的橡胶材质制作而成,形状一端封闭,另一端开口,开口端的密封凸缘上留有密封端面。
作为一种优选实施例,收缩囊4与水腔壳体的内壁之间具有间隙,以便于收缩囊4装入水腔壳体2中。
作为一种优选实施例,密封螺母5内侧延伸出有与通气孔51贯通的插管,插管***收缩囊4的开口端(参见图8)。
作为一种优选实施例,密封螺母5的端面上设有开启孔52(参见图4)。本方案中,为防止密封螺母5被误拆卸,结构上仅在端面设计两个开启小孔52,只能通过特殊工具拆卸。
实施例2
如图1至图4所示,根据本发明具体实施方式的一种水冷散热器,包括水冷排1以及收缩器,收缩器包括水腔壳体2以及至少一个收缩囊4,其中水冷散热器的冷却水经过水冷排1进行散热,水腔壳体2的内腔与冷却水连通,在本实施例中,水腔壳体2和水冷排1一体成型,或水腔壳体2焊接在水冷排1的一侧,水腔壳体2和水冷排1一体成型时水腔壳体2的内腔供水冷散热器的冷却水循环流过,收缩囊4内置在水腔壳体2内,收缩囊4与水腔壳体2的外侧通过通气孔51连通。
上述方案中,水腔壳体2和水冷排1一体成型,通过在水腔壳体2内增加一个或多个收缩囊4,收缩囊4与水腔壳体2的外侧(即,与外界大气)通过通气孔51连通,收缩囊4一般由弹性材料制成,通过收缩囊内径和长度大小调节容积大小,收缩囊4的容积随着整个水冷***压力在动态调节,温度上升压力增大时容积被压缩,温度下降压力减小时容积恢复(参见图2和图3),这种通过收缩囊4的体积变化,平衡***内外压力差,可以从根本上解决***内部压力过大而带来的漏液问题。
作为一种优选实施例,水腔壳体2沿水冷排1一侧的宽度方向呈长条形设置。实际上,水腔壳体2可以布置在水冷排1任意一侧,结构上不破坏原有液体流动方向,合理的空间大小布置不会增加冷排液体流动阻力。本实施例中,水腔壳体2可以设计成与水冷排1的厚度相当的长方形壳体结构。
作为一种优选实施例,水腔壳体2的一端内凹于水冷排1的侧面进而形成让位空间。如实施例1所述,当收缩囊4通过套管3和密封螺母5的形式设置在水腔壳体2上时,该让位空间用来容纳密封螺母5(参见图3),本方案中,水腔壳体2的形状不同于现有的水腔壳体2A(参见图5),现有的水腔壳体2A由于没有设置密封螺母5,水腔壳体2A的长度和水冷排1的宽度相当。
实施例3
如图6至图8所示,本实施例和实施例2的区别在于,水腔壳体2构造成独立的部件,然后该水腔壳体2通过连管7和水冷排1一侧的连通水道连通,此时,在水腔壳体2的另一端设有与连管7连接的接头。和实施例2相比,只是水腔壳体2的设置方式不同,当然也可以改变其形状,只要是其内部具有一定的容纳空间即可。在实施例3中,收缩囊4的设置方式和实施例1一样,此处不再赘述。
另外,需要说明的是,本实施的水冷散热器可以应用于电脑散热,水冷排1和水冷头6连通,通过水冷头6对电脑主机散热。当然,水腔壳体2既然可以构造成独立的部件,那么,水腔壳体2不一定与水冷排1一侧的连通水道连通,也可以和水冷排1和水冷头6的连通管路连通,也即水腔壳体2的内腔和水冷散热器的内部水循环连通即可。
综上,本实施例的用于水冷散热器的收缩器以及水冷散热器,通过设置收缩器和水冷散热器的冷却水连通,当***内部压力过大时,通过挤压收缩囊扩充内部体积,使得增加的压力得到释放,从根本上解决高压漏液的问题,不涉及外部体积变化,不需要增加额外部件,可以很好的兼容现有的硬件,相较常规水冷***外观尺寸变化不大,相较外接水箱的方案,成本低廉,技术难度底,容易维护。
前述对本发明的具体示例性实施方案的描述是为了说明和例证的目的。这些描述并非想将本发明限定为所公开的精确形式,并且很显然,根据上述教导,可以进行很多改变和变化。对示例性实施例进行选择和描述的目的在于解释本发明的特定原理及其实际应用,从而使得本领域的技术人员能够实现并利用本发明的各种不同的示例性实施方案以及各种不同的选择和改变。本发明的范围意在由权利要求书及其等同形式所限定。
