Description

散热装置和户外通讯设备
技术领域
本发明实施例涉及热交换技术,尤其涉及一种散热装置和户外通讯设备。 背景技术
在通信网络中, 存在大量放置于户外的户外通信设备, 例如通信基站大 功率机拒等等。 由于这些户外通信设备在工作时产生热量, 并且只有在一定 温度范围内才能够正常运行, 因此需要为这些户外通信设备设置散热装置。
图 1为现有的散热装置的结构示意图。如图 1所示, 该散热装置中包括: 内循环热交换单元、 外循环热交换单元、 蒸汽上升管、 液体下降管、 内循环 风扇、 外循环风扇以及风道隔板。 其中, 内循环热交换单元、 外循环热交换 单元、 蒸汽上升管以及液体下降管内部连通并充有载冷剂。 在设计上述散热 装置时, 需要根据应用其的户外通信设备的工作功率和工作环境, 设计内循 环热交换单元和外循环热交换单元的散热性能以及内循环风扇和外循环风扇 的性能。 在一个散热装置设计制作完成后, 它的散热性能是固定不变的。
运营商在进行通信网络建设时, 根据当前的业务需求在户外通信设备中 配置对应数量的业务单板, 并且预留一些用于放置业务单板的空余槽位。 在 通信网络初次建设完成后, 随着业务需求的不断增加, 需要对通信网络进行 扩容, 因此需要在上述空余槽位上增加业务单板, 以实现户外通信设备的升 级。 在户外通信设备升级后, 该设备的工作功率发生变化, 因此初次网络建 设设置的散热装置不适合升级后的户外通信设备。 目前在设置散热装置时, 考虑该户外通信设备存在后续升级的可能, 根据该户外通信设备配置最多的 业务单板时的工作功率设计散热装置, 因此制作成本高, 并且在该户外通信 设备没有配置最多的业务单板时存在成本浪费。 而如果仅仅根据初次网络建 设的户外通信设备的工作功率设置散热装置, 则在后期需要对户外通信设备 进行升级时, 必须整体更换户外通信设备, 会造成更大的成本浪费。 总之, 现有的散热装置无法与户外通信设备同步升级, 因此造成了户外通信设备的 制造成本浪费。 发明内容
本发明实施例提供一种散热装置, 用以解决现有技术中的缺陷, 降低制 造成本。
本发明实施例还提供一种户外通信设备, 用以解决现有技术中的缺陷, 降低制造成本。
本发明实施例提供一种散热装置, 包括: 至少一个热虹吸换热单元、 至 少一个第一隔板以及具有至少两个格子的框架;
每个热虹吸换热单元嵌入一个格子内;
每个未嵌入热虹吸换热单元的格子中设有一个可拆卸的将该格子分为上 下两部分的所述第一隔板。
本发明实施例还提供一种包含上述散热装置的户外通信设备, 该户外通 信设备还包括: 至少一个业务单板;
所述热虹吸换热单元的数量根据所述业务单板的数量确定。
由上述技术方案可知, 本发明实施例通过模块化设计, 散热装置的框架 具有多个可嵌入热虹吸换热单元的格子, 可以根据当前所需的散热性能, 随 时增加或减少嵌入的热虹吸换热单元的数量, 使得散热装置与其所在的设备 可以同步升级, 从而避免根据最大需求设计散热性能所造成的成本浪费, 节 约了制造成本。 并且, 该散热装置即插即用, 便于安装和维护, 满足了设备 升级的需要。 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对实 施例或现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面 描述中的附图仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附图。
图 1为现有的散热装置的结构示意图;
图 2为本发明实施例一的未组装的散热装置的结构示意图;
图 3为本发明实施例二的热虹吸换热单元的结构示意图;
图 4为本发明实施例三的组装后的散热装置的结构示意图。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于 本发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
图 2为本发明实施例一的未组装的散热装置的结构示意图。如图 2所示, 该散热装置至少包括: 至少一个热虹吸换热单元 1、 至少一个第一隔板 2 以 及具有至少两个格子的框架 3。 具体地, 每个热虹吸换热单元 1嵌入一个格 子内。 每个未嵌入热虹吸换热单元 1 的格子中设有一个可拆卸的将该格子分 为上下两部分的第一隔板 2。
在上述技术方案的基础上, 进一步地, 该散热装置中还可以包括: 至少 一个风扇单元 4。 具体地, 每个风扇单元 4嵌入由框架 3与一个第一隔板 2 组成的一个半格子内。
以下通过本发明实施例二对上述技术方案中的热虹吸换热单元 1进行详 细说明。
图 3为本发明实施例二的热虹吸换热单元的结构示意图。 在本发明实施 例二中, 热虹吸换热单元 1采用强化换热翅式的热虹吸管。 如图 3所示, 每 个热虹吸换热单元 1 包括: 一个位于上端的冷凝端汇流管 11、 一个位于下端 的蒸发端汇流管 12、至少两个连通蒸发端汇流管 12和冷凝端汇流管 11的散 热细管 13、 在每两个散热细管 13之间均匀分布的散热片 14, 以及一个将该 热虹吸换热单元 1分为上下两部分的第二隔板 15。
上述散热片 14可以采用多种形状。 较佳地, 上述散热片 14为波纹状散 热片。
在上述蒸发端汇流管 12、冷凝端汇流管 1 1和散热细管 13中填充载冷剂。 具体地, 该载冷剂可以采用如下材料中的任意一种, 但并不限于以下材料: 氨、 丙酮或 R134A型载冷剂。
该热虹吸换热单元 1经过第二隔板 15进行分隔。分隔得到的热虹吸换热 单元 1的下半部分包括蒸发端汇流管 12以及每个散热细管 13的下半部分, 设置于内循环风道中, 与散热装置所在的设备产生的热风接触。 在下半部分 的散热细管 13中, 液态的载冷剂与热风进行热交换, 载冷剂吸收热量, 因此 发生汽化反应, 生成蒸汽。该蒸汽沿着散热细管 13上升到分隔得到的热虹吸 换热单元 1的上半部分。 分隔得到的热虹吸换热单元 1的上半部分包括冷凝 端汇流管 11以及每个散热细管 13的上半部分, 设置于外循环风道中, 与散 热装置外的冷风接触。在上半部分的散热细管 13中,载冷剂的蒸汽与冷风进 行热交换, 载冷剂的蒸汽放出热量, 因此发生冷凝反应, 载冷剂恢复到液态。 液态的载冷剂由于重力作用沿着散热细管 13向下流动,返回分隔得到的热虹 吸换热单元 1 的下半部分。 如此往复循环, 将散热装置内部的热量传递到外 部, 从而实现散热功能。 图 4为本发明实施例三的组装后的散热装置的结构示意图。 在本发明实 施例三中, 对本发明实施例一中的散热装置进行组装, 以组装后的一个散热 装置为例。 如图 4所示, 该散热装置中包括: 具有八个格子的框架 3、 两个 热虹吸换热单元 1 以及六个第一隔板 2。 其中, 两个热虹吸换热单元 1分别 嵌入第二个和第三个格子内。 对于其余未嵌入热虹吸换热单元 1 的格子, 每 个格子中设有一个第一隔板 2, 每个第一隔板 2将所在的格子分为上下两部 分。 并且, 这些第一隔板 2是可以拆卸的。
在组装后的散热装置中, 多个第一隔板 2将多个格子均划分为上下两部 分。 其中, 所有格子的下半部分设置于内循环风道中, 与散热装置所在的设 备产生的热风接触。 所有格子的上半部分设置于外循环风道中, 与散热装置 外的冷风接触。 内循环风道与外循环风道由多个第一隔板 2实现隔离。
在实际应用中, 根据所需的散热性能确定热虹吸换热单元 1 的数量。 当 散热装置所在的户外通信设备升级时, 可以将当前未嵌入热虹吸换热单元 1 的格子中的第一隔板 2拆掉, 在该格子中嵌入新的热虹吸换热单元 1 , 以提 高该散热装置的散热性能。 在本实施例三中, 仅以设置两个热虹吸换热单元 1为例。
进一步地, 还可以根据所需的散热性能, 确定风扇单元 4的数量。 当需 要提高散热性能时, 将新增的风扇单元 4嵌入框架 3与第一隔板 2组成的半 格子内。 并且, 还可以根据内循环风道和外循环风道的气流强弱, 在内循环 风道和外循环风道中设置个数相同的风扇单元 4或个数不同的风扇单元 4。 在增加新的风扇单元 4时, 也可以根据实际需要, 仅在内循环风道或外循环 风道之一增加新的风扇单元 4。 在本实施例三中, 仅以在内循环风道和外循 环风道分别设置一个风扇单元 4为例。
在本发明实施例三中, 较佳地, 上述格子、 热虹吸换热单元 1 以及风扇 单元 4均为矩形。 具体地, 格子与虹吸换热单元的形状相同。 风扇单元 4的 宽度与格子和热虹吸换热单元 1的宽度相同, 风扇单元 4的高度是格子和热 虹吸换热单元 1 高度的一半。 在其它的实施例中, 格子、 热虹吸换热单元 1 以及风扇单元 4还可以采用其它形状。
本发明实施例一至本发明实施例三的散热装置可以应用到户外通信设备 中。 具体地, 该户外通信设备中包括散热装置和至少一个业务单板, 该散热 装置采用本发明实施例一至本发明实施例三中记载的散热装置。 该散热装置 中的热虹吸换热单元的数量根据业务单板的数量确定。 当该户外通信设备升 级时, 其中的业务单板数量增加, 相应地增加散热装置中的热虹吸换热单元。 进一步地,该散热装置中的风扇单元的数量也可以根据业务单板的数量确定。 当该户外通信设备升级时, 其中的业务单板数量增加, 相应地增加散热装置 中的风扇单元。
在本发明实施例一至本发明实施例三中, 采用模块化设计, 散热装置的 框架具有多个可嵌入热虹吸换热单元的格子,可以根据当前所需的散热性能, 随时增加或减少嵌入的热虹吸换热单元的数量, 使得散热装置与其所在的设 备可以同步升级, 从而避免现有的散热装置根据最大需求设计散热性能造成 的成本浪费, 节约了制造成本。 并且, 该散热装置即插即用, 便于安装和维 护, 满足了设备升级的需要。

在上述实施例中, 对各个实施例的描述都各有侧重, 某个实施例中没有 详述的部分, 可以参见其他实施例的相关描述。
本领域普通技术人员可以理解: 实现上述方法实施例的全部或部分步骤 可以通过程序指令相关的硬件来完成, 前述的程序可以存储于一计算机可读 取存储介质中, 该程序在执行时, 执行包括上述方法实施例的步骤; 而前述 的存储介质包括: ROM、 RAM, 磁碟或者光盘等各种可以存储程序代码的介 质。
