Description
技术领域
本发明属于散热器领域，具体涉及一种用于电子元件的水冷散热器。
背景技术
在水冷散热器领域，铜导热性能比铝更好，且耐腐蚀性能也更优异，但是铜的成本比铝高；企业综合考虑成本和性能，开发出了一种铜管嵌入铝块中的水冷散热器，即可以利用铜导热性和耐腐蚀性大量向铜管中的冷水传导热量，以及防止管道被水腐蚀而堵塞；又控制了成本。将铜管嵌入铝块的工艺很多，其中最简单的方式就是在铝块中设置凹槽，通过导热胶黏剂将铜管粘接在凹槽内。
现有技术中，铜管的出水段温度高，不仅丧失冷却作用，可能还会将热量重新传导给被进水段冷却的铝块，降低了冷却效率。
发明内容
本发明所要解决的技术方案是：提供一种水冷散热器，能够提高散热的效率。
本发明所采取的技术方案是：一种水冷散热器，包括安装电子元件的铝板，铝板上开有凹槽，凹槽内设置铜管，铜管分为两段，一段为蛇形的进水段，一段为直线型的出水段；所述的进水段与凹槽之间通过导热胶黏剂粘接，出水段与凹槽之间通过弱导热胶黏剂粘接。
进一步地，所述出水段与凹槽之间通过弱导热胶黏剂粘接，粘接方式为靠近出水口部分粘接，其余部分通过导热胶黏剂粘接或不采用胶黏剂粘接。
进一步地，所述凹槽的截面为矩形或者U形。
本发明的有益效果是：在铜管的出水段，特别是出水段的末端部分设置导热性能差的胶黏剂或者不设置胶黏剂，增加了铜管与铝块热阻，阻止高温冷却水对局部被冷却至低温的铝块热传导，提高冷却效率。

图2为所述一种水冷散热器的俯视图；
图3为所述一种水冷散热器凹槽为矩形的示意图；
图4为所述一种水冷散热器凹槽为U形的示意图。
