Description

LED灯的散热系统
【技术领域】
本发明涉及一种LED灯的散热系统。
【背景技术】
众所周知，LED具有发光效率高、寿命长和耗电少，因此受到广泛的推广应用，但是，由于LED灯应用时温度过高，会使发光强度降低，从而影响发光效率及照明质量，并且严重影响其使用寿命，特别是应用在大功率的LED灯上，尤为突出，因此温度过高的技术问题成为LED灯普及推广的一大阻碍。
现有LED灯的散热主要由风冷散热结构和液冷散热结构两种，风冷散热由于冷却速度慢，难于适从大功能LED灯使用，而液冷散热效果虽然比风冷散热好，但结构上仍存在许多技术缺陷，体积大，成本高，因此使用受到限制，仍然难于普及。且LED灯应用时，电源板同样会产生大量的热量，以致影响整个LED灯的使用寿命，到目前为止，对电源板的散热问题仍然没有得到技术人的关注和重视。
【发明内容】
有鉴于此，有必要提供一种具有良好散热功能的LED的散热系统。
一种LED灯的散热系统，包括循环管和泵，还包括有LED散热模组和电源散热模组，所述LED散热模组为LED灯的流体散热装置，电源散热模组为LED灯电源模块的流体散热装置；所述循环管连接于LED散热模组和电源散热模组；所述泵安装在循环管上，使循环管内的流体经过LED散热模组和电源散热模组形成循环式流动。
在其中一个实施方式中，所述循环管上还设有一散热器。
在其中一个实施方式中，所述散热器包括有风扇和过水道，所述过水道由若干条截面呈方形的片状输送管构成，各片状输送管上分别设有一条波浪形片状结构的散热片；所述散热片用于导出片状输送管内流体的热量；所述片状输送管的输入口和输出口分别与循环管对接，使循环管的流体循环流动经过过水道时导热至散热片进行降温，所述风扇安装在过水道一侧，使风扇送风穿过过水道和散热片，实现快速降温功能。
在其中一个实施方式中，所述过水道的输入口和输出口分别设有一盛装流体的集水箱，所述集水箱分别设在过水道、散热片两端，与过水道、散热片形成一体式结构，或所述的输入口或输出口设有一盛装流体的集水箱，所述的循环管通过集水箱与过水道相接。
在其中一个实施方式中，所述LED散热模组为贴紧在LED灯底座上的采用具有良好导热材料制成的盛装流体的第一密封箱体，包括有密封壳体，所述密封壳体上设有外接循环管的输入口和输出口，密封壳体通过输入口注入循环散热流体，通过输出口输出循环散热流体，该密封壳体侧面板由一散热板构成，该散热板贴在发热体上，将发热体的热量通过散热板传导至密封壳体内的散热流体中进行循环散热。
在其中一个实施方式中，所述电源散热模组为贴紧在电源模块上的采用具有良好导热材料制成盛装流体的第二密封箱体。
在其中一个实施方式中，所述的第一密封箱体和第二密封箱体内均设有散热管，该散热管穿过第一密封箱体和第二密封箱体内，散热管的进/出口分别连接于循环管。
在其中一个实施方式中，所述LED散热模组、电源散热模组与循环管采用并联或串联方式进行连接。
在其中一个实施方式中，所述流体包括硅油、水等具有良好导热性能的冷却液。
在其中一个实施方式中，所述的散热板内侧设有若干片散热片，该散热片均匀布满在密封壳体的内腔中。
在其中一个实施方式中，所述的散热板上设有安装槽，所述密封壳体为方形或圆形壳体，壳体的四周侧边与安装槽紧密配合，安装在散热板上。
在其中一个实施方式中，所述的侧板与安装槽的配合位置处采用防渗漏密封材料填充。
在其中一个实施方式中，所述的散热板与发热体之间采用导热胶相互贴紧。
在其中一个实施方式中，所述的发热体为LED灯或电源模块。
在其中一个实施方式中，所述的循环管或/和密封壳体采用具有导热性能的材料制作而成。
在其中一个实施方式中，所述散热系统还包括一保护装置，该保护装置包括有温度传感器和控制电源线路。
本实施方式的散热系统具有以下突出的有益效果：
所述散热系统包括循环管、泵、LED散热模组和电源散热模组，这样不但对LED灯进行散热，同时还对电源模块进行散热，因此，有效地保障整个LED灯设备的散热效果，提高LED灯的照明效果和质量，同时防止电源模块受热受损，以致可有效延长使用寿命。一实施方式的循环管上设有一散热器，该散热器包括有风扇和过水道，所述过水道由若干条截面呈方形的片状输送管构成，由此可增大过水道的散热面积，减小散热器的体积，并可有效提高LED灯的散热效果。
在本实施方式的散热系统中，片状输送管上分别设有一条波浪形片状结构的散热片；所述散热片用于导出片状输送管内流体的热量，因此，可扩大过水道的导热、散热面积，可进一步减少散热器的体积，将过水道内流体（包括硅油、水等具有良好导热性能的冷却液）的热量导出，进而进一步提升流体的降温功能，实现更佳的散热效果，使LED灯和电源模块、甚至整个LED灯设备（即LED灯具）得到更好的降温散热功能，以致有效提高LED灯的使用性能和延长LED灯的使用寿命。
在本实施方式的散热系统中，过水道的输入口和输出口分别设有一集水箱，或所述的输入口或输出口设有一盛装流体的集水箱，所述的循环管通过集水箱与过水道相接，由此增加循环管内流体的循环量，以致提高LED灯的散热效果。
在本实施方式的散热系统中，集水箱与过水道、散热片为一体式结构，因此结构紧凑、安装便捷，组装效率高。
在本实施方式的散热系统中，散热系统还包括一保护装置，因此，使一实施方式的LED灯使用时得到更好的自我保护功能，避免散热功能失灵或受损时，LED灯同样受损，甚至毁坏。

以下结合附图对本发明作进一步的详细说明。
第一实施例：如图1至图7所示的一种LED灯的散热系统，包括循环管1和泵2，还包括有LED散热模组3和电源散热模组4，所述LED散热模组3为LED灯5的流体散热装置，电源散热模组4为LED灯电源模块6的流体散热装置；所述循环管1连接于LED散热模组3和电源散热模组4；具体连接方式如图1和图2所示：LED散热模组3、电源散热模组4与循环管1采用并联方式进行连接；所述泵2安装在循环管1上，使循环管1内的流体经过LED散热模组3和电源散热模组4形成循环式流动，从而同时实现LED灯5和电源模块6的散热降温功能。
具体在实施例中，所述循环管1包括有软管或具有散热功能金属管，如胶管、铝管或铜管等。为了提高流体的散热效率，在循环管1上还设有一散热器7，该散热器7包括有风扇71和过水道72，同时为了增强过水道72的散热面积，所述过水道72由若干条截面呈方形的片状输送管721构成，并在各片状输送管721上分别固定有一条波浪形片状结构的散热片73，各散热片73与各片状输送管721相互固定形成一体式结构，以增强过水道72内流体的导热及冷却散热功能，所述的过水道72和散热片73均采用具有良好导热材料制成，如铜、铝等金属材料；所述散热片73用于导出片状输送管721内流体8的热量；所述片状输送管721的输入口723和输出口724分别与循环管1对接，使循环管1的流体循环流动经过过水道72时导热至散热片73进行降温；所述的风扇71安装在过水道72一侧，使风扇71送风穿过过水道72和散热片73，实现快速降温功能。
进一步的，所述过水道72的输入口723和输出口724分别设有一盛装流体的集水箱9。所述若干条片状输送管721为上下式分布，如图3所示，各散热片73间隔设在各片状输送管721上相互固定；所述集水箱9分别设在过水道72、散热片73两端，与过水道72、散热片73形成一体式结构。即多块片状输送管721由上下分布进行排列，各块片状输送管72分别设有一波浪形的散热片73，在过水道72两侧分别设有盛装流体的集水箱9，片状输送管721的输入口723和输出口724分别接入两侧的水箱9，所述循环管1通过集水箱9与过水道72的片状输送管721相接，使循环管1内的流体8循环流动时在过水道72一侧的集水箱9通过片状输送管721流动至另一侧的集水箱9。
所述LED散热模组3为贴紧在LED灯底座上的采用具有良好导热材料（如铜、铝等金属材料）制成盛装流体的的第一密封箱体，如图5和图7所示，所述LED散热模组3为贴紧在LED灯底座上的采用具有良好导热材料制成的盛装流体的第一密封箱体，包括有密封壳体3-1，所述密封壳体3-1上设有外接循环管1的第一输入口31和第一输出口32，密封壳体3-1通过输入口31注入循环散热流体8，通过输出口32输出循环散热流体8，该密封壳体3-1一侧面板由一散热板3-6构成，该散热板3-6贴在发热体3-7上，将发热体3-7的热量通过散热板3-6传导至密封壳体3-1内的循环散热流体8中进行循环散热。所述第一密封箱体的第一输入口31和第一输出口32分别连接于循环管1。所述电源散热模组4为贴紧在电源模块6上的采用具有良好导热材料（如铜、铝等金属材料）制成盛装流体的的第二密封箱体。所述第二密封箱体的第二输入口41和第二输出口42分别连接于循环管1。
进一步的：所述的发热体3-7为LED灯3-71。所述的散热板3-6内侧设有若干片散热片3-61，该散热片3-61位于散热流体8中，散热片3-61与散热板3-6采用铝或铜等具有良好导热性能的金属材料一体成型，散热片3-61平行排列在散热板3-6上，均匀布满在密封壳体3-1的内腔中，使散热片更好地将发热体热量通过散热板3-6和散热片3-61传导至散热流体中，该散热流体8可采用硅油、水等具有良好导热性能的冷却液。
所述的散热板3-6与发热体3-7之间采用导热胶3-8相互贴紧，如采用散热硅胶，以致可使发热体3-7的热量更好地通过导热胶3-8传导至散热板3-6，通过散热板3-6和散热片3-61传导至散热流体8中。考虑到能更好地提高散热效果，所述密封壳体1和循环管2均采用具有导热性能的材料制作而成，如铝、铜等材料。
所述的第一密封箱体和第二密封箱体内均设有散热管10，该散热管为S型、环形、一字型排列等结构的铜管、铝管、或陶瓷管，该散热管10穿过第一密封箱体和第二密封箱体内，散热管10的进/出口分别连接于循环管1。简单地说，所述散热管10为穿过盛满流体的第一密封箱体和第二密封箱体内用于流体循环流动的输送管。
所述散热系统还包括一保护装置，该保护装置包括有温度传感器和控制电源线路，该温度传感器设在LED灯6底座位置，控制电源线路连接于电源模块6。当温度传感器检测到LED灯底座位置的温度信息后，该温度信息经控制电源线路传送到电源模块6中，电源模块6接收到温度信息后，判断是否超过预设值，当超过预设值时，立马关闭LED灯，停止使用，由此实现自我保护功能。
一实施例在应用时，在LED散热模组3（第一密封箱体）、电源散热模组4（第二密封箱体）和集水箱9内均充满流体8，该流体8包括有水或冷却液等具有良好导热性能的液体。开启LED灯时，同时启动循环管1上的水泵2，使流体8在LED灯5的LED散热模组3（第一密封箱体）、电源模块6的电源散热模组4（第二密封箱体）和散热器7的集水箱9之间循环流动。流体循环过程中，LED灯5产生的热量经LED散热模组3内的流体传导至散热管10内的循环流体中，电源模块6产生的热量经电源散热模组4内的流体再传导至散热管10内的循环流体中，当循环流体流动时，通过循环管1使带热量的循环流体经过散热器7的片状输送管721，流体带出的热量通过片状输送管721和散热片73导出，由风扇71吹风降温，实现流体8快速散热降温，最后再循环流动回LED散热模组3和电源散热模组4对LED灯5和电源模块6进行再次降温，如此反复循环实现LED灯5和电源模块6的良好散热功能。
第二实施例：本实施例的技术特点是：所述LED散热模组3（第一密封箱体）和电源模块6的电源散热模组4（第二密封箱体）内无需散热管10。其余同上实施例。
一实施例在应用时，在LED散热模组3（第一密封箱体）、电源散热模组4（第二封箱体）和集水箱9内充满流体8，该流体8包括硅油、水等具有良好导热性能的冷却液。开启LED灯时，同时启动循环管1上的水泵2，使流体8在LED灯5的LED散热模组3（第一密封箱体）、电源模块6的电源散热模组4（第二密封箱体）和散热器7的集水箱9之间循环流动。流体循环过程中，LED灯5产生的热量经LED散热模组3传导至循环流体中，电源模块6产生的热量经电源散热模组4传导至循环流体中，当循环流体流动时，通过循环管1使循环流体经过散热器7的片状输送管721，流体带出的热量通过片状输送管721和散热片73导出，由风扇71吹风降温，实现流体8快速散热降温，最后再循环流动回LED散热模组3和电源散热模组4对LED灯5和电源模块6进行再次降温，如此反复循环实现LED灯5和电源模块6的良好散热功能。
第三实施例：如图8至图10所示的一种LED灯的散热系统，本实施例的技术特点是：所述LED散热模组3、电源散热模组4与循环管1采用串联方式进行连接。为了便于安装，所述的散热板3-6上设有安装槽3-62，所述密封壳体1的四周侧边3-11与安装槽3-62紧密配合，安装在散热板3-6上。为了提高安装的紧密性和稳定性，所述的侧板3-11与安装槽3-62的配合位置处采用防渗漏密封材料填充或在安装槽3-62上设有密封胶条。所述的发热体3-7为电源模块3-72。其余同上实施例。
实施例4：本实施例的技术特点是：所述的输入口723或输出口724设有一盛装流体的集水箱9，采用单一集水箱。其余同上实施例。
由于所述散热系统包括循环管、泵、LED散热模组和电源散热模组，这样不但对LED灯进行散热，同时还对电源模块进行散热，因此，有效地保障整个LED灯设备的散热效果，提高LED灯的照明效果和质量，同时防止电源模块受热受损，以致可有效延长使用寿命。由于所述循环管上设有一散热器，该散热器包括有风扇和过水道，所述过水道由若干条截面呈方形的片状输送管构成，由此可增大过水道的散热面积，减小散热器的体积，并可有效提高LED灯的散热效果。
由于一实施例中的片状输送管上分别设有一条波浪形片状结构的散热片；所述散热片用于导出片状输送管内流体的热量，因此，可扩大过水道的导热、散热面积，可进一步减少散热器的体积，将过水道内流体（包括硅油、水等具有良好导热性能的冷却液）的热量导出，进而进一步提升流体的降温功能，实现更佳的散热效果，使LED灯和电源模块、甚至整个LED灯设备（即LED灯具）得到更好的降温散热功能，以致有效提高LED灯的使用性能和延长LED灯的使用寿命。
由于一实施例中的过水道的输入口和输出口分别设有一集水箱，或所述的输入口或输出口设有一盛装流体的集水箱，所述的循环管通过集水箱与过水道相接，由此增加循环管内流体的循环量，以致提高LED灯的散热效果。
由于一实施例中的集水箱与过水道、散热片为一体式结构，因此结构紧凑、安装便捷，组装效率高。
由于一实施例中的散热系统还包括一保护装置，因此，使一实施例的LED灯使用时得到更好的自我保护功能，避免散热功能失灵或受损时，LED灯同样受损，甚至毁坏。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
