Description

一种冷却器
技术领域
本发明涉及一种散热器，特别是适用于电子元器件的散热器。
背景技术
目前用于电子元器件的散热器多为铝合金散热器，它已不足于满足现代大功率电子元器件的散热要求，例如，速度不断提升的电脑中央处理器(CPU)，以及电子装置交直流电机的大功率变频器产生的热量，均需高效能的散热装置，而由铝合金制造的齿状散热器已无法承担此散热功能的效果。同时，由纯铜制造的散热器成本高、体重大，对电子装置的有限空间、重量和成本构成限制。
发明内容
本发明的目的是针对上述问题，提出一种冷却器，它能满足电子元器件高效的散热要求，同时具体积小、重量轻的特点。
本发明由一个或以上的U型铜管、密封容器、浸泡有冷却液体的强力吸水纤维组成，密封容器上端设置有孔洞，U型铜管的管口被焊接对应固定在密封容器的孔洞上，浸泡有冷却液体的强力吸水纤维置放在密封容器内。
上述冷却器还外置一冷却风扇，该冷却风扇由固定支架固定在U型铜管一侧。该风扇的设置目的是冷却U型铜管内的汽化水，使其回流到密封容器内再循环使用。
上述的密封容器由上、下两半盒体组成，下半盒体底部设有凸平台，上半盒体设有凸孔洞。下半盒凸平台的设置目的与发热介面有一良好接触，增强发热和导热效果；上半盒的凸孔洞用来焊接固定U型铜管的管口。
上述的密封容器的上、下两半盒体经机械式抽取盒内真空后由硅胶密封圈密封成真空容器。
上述强力吸水纤维含有的冷却液采用抑制型二醇基液体。
本发明采用无氧纯铜板密封制造的容器，储存抑制型二醇基导热流体的内置强力吸水纤维，U型铜管的内孔通道作为蒸发器，通过热传产生汽化流体在U型铜管内孔中积聚、受风扇冷却冷凝、液体回流，再循环冷却以达到高效散热效果。
附图说明
现结合附图对本发明做进一步详述：
附图1是本发明结构示意图；
附图2是附图1的K向视图；
附图3是密封容器上半盒体结构示意图；
附图4是密封容器下半盒体结构示意图；
附图5是U型铜管结构示意图；
附图6是风扇固定架结构示意图。
具体实施方式
如附图1、附图2所示，本发明由U型铜管1、密封容器2和浸泡有冷却液体的强力吸水纤维3组成。
如附图3、附图4所示，密封容器2由以模具冲压成盒状型的上半盒体21和下半盒体22组成，下半盒体22向下凸出约5mm高的凸平台221，凸平台221的长、宽和发热体接触面大小一致，以保证凸平台221与发热体表面最佳接触，以增强散热及导热效果。上半盒体21上部分被冲压有两个或倍数以上的凸孔洞211，该凸孔洞211与U型铜管1的管口大小相同。
如附图5所示，U型铜管1由平直无氧纯铜管经模具弯曲加工而成，为了能有足够的通道长度接纳汽化水冷凝，U型铜管1的高度比例最小设计是密封容器2高度的2倍或以上，该U型铜管1固定在密封容器2的上半盒体21的各对称凸孔洞211中。
强力吸水纤维3浸泡有抑制型二醇基导热溶液，其置放在密封容器2内腔，如附图1、附图2所示。密封容器2的上、下半盒体21、22经机械式抽取真空后再采用硅胶密封圈密封成一真空密封容器。
该散热器的外壳经电镀镍处理以增强表面导热功能。
如附图6所示，冷却风扇固定支架4一端为自锁铜管机构41，其以自锁形式固定在U型铜管1上，冷却风扇固定在支架4的锁定位42上。
本发明采用一种特殊配制的抑制剂，例如抑制型二醇基导热流体(DOWTERM和DOWFROST的产品)，性能特别适用于闭环水基加热、通风和冷却(HVAC)过程中导热和冷却，既可保护金属表面防氧化，又能起到抗腐蚀的作用。
抑制型二醇基流体实际上是水和抑制型二醇基溶液，流体中的二醇浓度能直接影响其性能和特性，通常电子元器件正常使用时，合理的温度不能超过60度，二醇浓度比例在35～40％，水占60～65％之间为最佳。故本发明的真空密封容器2内流体在60度以上温度时。冷却液达到微量汽化开始往上升向U型铜管1的内孔中，而U型铜管1的侧部通过风扇安装支架4置有冷却风扇，风扇在正常运转下冷却了U型铜管1的顶部和表面，使U型铜管1内上升的汽化水受到冷却、凝固成小水珠，在小水珠聚集到一定量后，重力作用就回流到密封容器2的内腔，被强力吸水纤维3储存，这种无消耗、密封在真空密封容器2中进行热传循环的汽化水回流原理实现了该发明的最佳散热效果。而该散热器壳体采用无氧纯铜板冲制，外壳镀镍，既能起到表面防氧化的保护，又可作为极佳的导热材料。
另外，U型铜管1装置愈多，热交换面积愈大，冷却效果则愈佳，U型铜管1的数量可根据热交换面积的需要来设计。
