Description

一种肋片换热系统 技术领域
本实用新型涉及换热系统技术领域，更具体地，涉及一种肋片换热系统。
 背景技术
一些用电装置，例如舞台灯具在使用时，其内部各种电子器件，特别是光源，会产生大量的热量，如果这些热量得不到及时转移，累积在机壳内部会造成温度升高，而过高的温度会影响灯具使用效果及使用寿命。当舞台灯要求IP65的防护等级而进行外壳完全密闭时，上述因热量累积而造成温度上升的情况会更加严重，因此，需对外壳完全密闭的高防护等级的舞台灯具的内部环境温度进行高效冷却。
现有技术中，通过内部强制循环把内部热量转移到外壳上，再通过外壳传导到壳体外表面进行自然散热来实现内部热量到外部环境的转移。现有技术由于外壳材料及制造工艺水平的限制，普遍存在传热热阻大、换热面积不足而造成换热效率低下的问题。
 技术问题
本实用新型的目的在于克服现有技术的不足，提供一种肋片换热系统，结构简单，使用方便，换热面积大、换热效率高，能延长需冷却的装置的寿命。
 技术解决方案
为达到上述目的，本实用新型采用的技术方案是：
提供一种肋片换热系统，包括散热腔体、肋片、导风结构及底座；所述散热腔体与外界隔绝，肋片及导风结构均与底座连接；所述导风结构及肋片通过底座与散热腔体连通以将散热腔体内的热量散发出去。所述外界为自然界。
上述方案中，将该肋片换热系统安装在需冷却的装置的内部后，当需冷却的装置产生热量时，热量从散热腔体进入导风结构内并利用肋片散发出去，且热量散发的过程中散热腔体与导风结构能形成循环通道，以增大换热面积，提高换热效率，该肋片换热系统能延长需冷却的装置的寿命。
优选地，所述导风结构为若干导风管。进一步优选地，所述导风管镶嵌在肋片中，每个导风管的两端通过底座与散热腔体连通。更进一步优选地，相邻导风管等间距均匀设置。这样设置使得热量能均匀地传输至导风管内，进而保证热量更好地散发出去。
优选地，所述散热腔体包括进风腔及出风腔。这样设置使得热量从进风腔进入导风结构内，一部分热量经肋片散发至外界，另一部分热量继续传输至出风腔内，从出风腔流出的热量可再次进入进风腔，由此热量达到循环流通，且进风腔及出风腔的设置可增加循环通道长度，便于热量更好地流通和散发至外界。
优选地，每个导风管的两端分别设于进风腔和出风腔内。这样设置能保证热量更好地传递和散发出去。
优选地，每个导风管在进风腔或/和出风腔的一端能延长至进风腔或/和出风腔外的任意位置。进一步优选地，所有导风管延长出进风腔或/和出风腔外的长度不一致。这样设置使得热量能更好地传输并散发出去，散热效果显著。
优选地，每个导风管在所述进风腔或/和出风腔的延长端设置辅助导风装置。这样设置使得待冷却的装置产生的热量能顺利地传输至进风腔和出风腔内，便于热量在循环通道内的流通，进而提高散热效果；辅助导风装置为导风板。
优选地，所述换热系统还包括设于进风腔或出风腔风道延长路径任意位置的第一驱风装置，第一驱风装置用于加强散热腔体内部空气对流。
优选地，所述换热系统还包括用于增强肋片与外界换热效率的第二驱风装置。进一步优选地，第二驱风装置风向与肋片平行。这样设置使得该换热系统散热效果更好。
 有益效果
与现有技术相比，本实用新型的有益效果是：
本实用新型一种肋片换热系统，将该肋片换热系统安装在需冷却的装置的内部后，当需冷却的装置产生热量时，热量从散热腔体进入导风结构内并利用肋片散发出去，且热量散发的过程中散热腔体与导风结构能形成循环通道，以增大换热面积，提高换热效率，该肋片换热系统能延长需冷却的装置的寿命。

将该肋片换热系统安装在需冷却的装置的内部后，本实施例中需冷却的装置为舞台灯具，该肋片换热系统安装在灯具内腔12内，当舞台灯具的发光部件产生热量时，热量从散热腔体进入导风结构2内并利用肋片1散发出去，且热量散发的过程中散热腔体与导风结构2能形成循环通道，以增大换热面积，提高换热效率，该肋片换热系统能延长舞台灯具的寿命。
其中，所述导风结构2为若干导风管。本实施例中，所述导风管镶嵌在肋片1中，每个导风管的两端通过底座4与散热腔体连通。相邻导风管等间距均匀设置。这样设置使得热量能均匀地传输至导风管内，进而保证热量更好地散发出去。
另外，所述散热腔体包括进风腔6及出风腔5。这样设置使得热量从进风腔6进入导风结构2内，一部分热量经肋片1散发至外界，另一部分热量继续传输至出风腔5内，从出风腔5流出的热量可再次进入进风腔6，由此热量达到循环流通，且进风腔6及出风腔5的设置可增加循环通道长度，便于热量更好地流通和散发至外界。
其中，每个导风管的两端分别设于进风腔6和出风腔5内。这样设置能保证热量更好地传递和散发出去。
另外，每个导风管在进风腔6或/和出风腔5的一端能延长至进风腔6或/和出风腔5外的任意位置。本实施例中，所有导风管延长出进风腔6或/和出风腔5外的长度不一致。这样设置使得热量能更好地传输并散发出去，散热效果显著。
其中，每个导风管在所述进风腔6或/和出风腔5的延长端设置辅助导风装置。这样设置使得发光元件产生的热量能顺利地传输至进风腔6和出风腔5内，便于热量在循环通道内的流通，进而提高散热效果；辅助导风装置为导风板。
另外，所述换热系统还包括设于进风腔6或出风腔5风道延长路径任意位置的第一驱风装置7，第一驱风装置7用于加强散热腔体内部空气对流。本实施例中，第一驱风装置7设于进风腔6风道延长路径任意位置。
其中，所述换热系统还包括用于增强肋片1与外界换热效率的第二驱风装置9。本实施例中，第二驱风装置9风向与肋片1平行。这样设置使得该换热系统散热效果更好。
