Abstract
一种散热装置,包括热管,散热鳍片组,用于对该散热鳍片组散热的风扇,以及一具有良好导热性的机壳,该热管具有与发热电子元件热接触的蒸发端,以及与该机壳及散热鳍片组相结合的两冷凝端。该散热装置零件少,结合程序简单,从而可减少产品重量与成本。
Description
【技术领域】
本发明是涉及一种散热装置,特别是涉及一种对发热电子元件散热的散热装置。
【背景技术】
随着电子产业的快速发展,电子元件的高速、高频以及集成化使其发热量剧增,因此散热已成为业者所重点考虑的问题。
在散热领域中,现有技术通常是采用一种散热模组对发热电子元件进行散热,该散热模组包括板体,设于该板体上部的风扇与若干散热鳍片组,以及设于该板体下部的若干热管,其中,该热管一端贴设于发热电子元件上部,另一端与该散热鳍片组连接,该散热模组通过热管将发热电子元件产生的热量传递到散热鳍片组上并利用风扇运转产生的气流将散热鳍片组处的热量散发到周围空气中,以达到对发热电子元件散热的目的。
该散热模组先将散热鳍片组、风扇、热管与板体结合,再将板体固定于机壳上,从而导致散热模组零件过多,结合程序复杂,进而增加了产品重量与成本,需加以改进。
【发明内容】
有鉴于此,有必要提供一种减少产品重量与成本的散热装置。
该散热装置包括热管,散热鳍片组,用于对该散热鳍片组散热的风扇,以及一具有良好导热性的机壳,该热管具有与发热电子元件热接触的蒸发端,以及与该机壳及散热鳍片组相结合的两冷凝端。
该散热装置与传统的散热模组相比,无需先将散热元件固定于板体上,不仅可节省板体等其它元件的用量,且结合程序简单,从而可减少产品重量与成本,还可增加散热面积,提高散热效果。
【附图说明】
图1是本发明散热装置的立体组装图。
图2是本发明散热装置的立体分解图。
图3是图1中热管与机壳结合剖面的局部放大图。
【具体实施方式】
下面参照附图结合实施例对本发明作进一步说明。
请参照图1及图2,本发明散热装置10包括一具有良好导热性的镁铝合金机壳100,与位于机壳100内的发热电子元件160接触且具有良好导热性的均热板110,两根热管120、130,固定于该机壳100上的散热鳍片组140以及用于对该散热鳍片组140散热的风扇150。
该热管120、130为扁平状,其分别具有蒸发端121、131与冷凝端122、132,该均热板110固定于机壳上,该均热板110上设有一槽111,该热管120、130的蒸发端121、131分别收容于该槽111的两端,该热管130的冷凝端132与散热鳍片组140结合,该热管120的冷凝端122固定在机壳100上,直接与该机壳100结合。
请参照图3,该热管120的冷凝端122可通过一固定弹片123与螺钉124锁附于该机壳100上。该固定弹片123具有一ㄇ型的收容部127,以及沿该收容部127两侧延伸并与机壳100相贴合的两固定部126,该固定部126与机壳100接触,并通过螺钉124进行固定,该热管120的冷凝端122固定于该固定弹片123的收容部127内,并在该热管120与机壳100结合处涂抹一层热传导介质125,以使两者结合得更为紧密,具有良好的热传导效果。
请再参照图1及图2,风扇150直接固定于机壳100上,该风扇150包括壳体151、装设于该壳体151上的定子(图未示)及可相对该定子转动的转子152。该风扇150在壳体151上设置有进风口153,并在壳体151侧壁设置与该等进风口153垂直的出风口154,散热鳍片组140位于风扇150的出风口154处并直接固定于机壳100上。该风扇150运转时,将其周围的冷空气由进风口153吸入壳体151内,经加压后由出风口154处排出,吹向散热鳍片组140,形成冷却该散热鳍片组140的气流。
该散热装置10通过热管120吸收设于均热板110上的发热电子元件160产生的热量并传递到机壳100与散热鳍片140上,使一部分热量直接通过机壳100散发,另一部分通过散热鳍片组140散发到周围的空气中。该散热装置将风扇、散热鳍片组、热管直接与导热性良好的机壳结合以对发热电子元件散热,与传统的散热模组相比,无需先将散热元件固定于板体上,不仅可节省板体等其它元件的用量,且结合程序简单,从而可减少产品重量与成本,还可增加散热面积,提高散热效果。
本发明中,该热管为两根,分别具有一蒸发端与一冷凝端;该热管120的冷凝端122通过一固定弹片123与螺钉124锁附于该机壳100上,实际应用中,热管可为一根或更多,如三根、四根等,当热管为一根时,其中间为蒸发端,两端为冷凝端,其中一冷凝端固定于机壳100上,另一冷凝端与散热鳍片组140相结合;该热管120的冷凝端122也可直接焊合于机壳100上。
