所述机拒 300包括一个拒体 310, 多个设置在所述拒体 310内的电器元件 320, 以及一个设置在所述拒体 300—侧的保护罩 330。
所述 TEC制冷装置 400包括 TEC模块 410, 第一热交换装置 440, 以及 第二热交换装置 430。
所述 TEC模块 410包括一个冷端 412, 以及一个与冷端相对的热端 414。 所述第一热交换装置 440及第二热交换装置 430分别设置在所述 TEC模 块 410的冷端 412及热端 414上。
本实施例中, 所述 TEC模块 410还包括一个设置在热端 414及第二热交 换装置 430之间的导热板 416用以导热。
所述第一热交换装置 440包括一个散热块 422, 第一导热件 424, 温控相 变模块 426, 以及第二导热件 428。
所述散热块 422设置在所述 TEC模块 410的冷端 412。 所述第一导热件 424的一端设置在所述散热块 422上并与所述散热块 422接触, 所述第一导热 件 424的另一端与所述温控相变模块 426连接。
本实施例中所述第一导热件 424可以采用热管、热虹吸管或者蒸汽腔等高 导热装置, 其包括一个蒸发端 424a及冷凝端 424b。 所述冷凝端 424b设置在 所述散热块 422上, 而所述蒸发端 424a连接在所述温控相变模块 426上。
所述温控相变模块 426设置在机拒 300的拒体 310上,所述温控相变模块 426可以采用相变材料如石蜡材料制成。 所述温控相变模块 426会在不同的温 度下呈现不同的状态以蓄积一定的热能或者冷能, 从而能保证所述机拒 300 内部的温度不发生剧烈的变化而影响电器元件 320的运作。
所述第二导热件 428的一端设置在温控相变模块 426上,另一端伸入所述 拒体 310内。本实施例中所述第二导热件 428可以采用与第一导热件 424相同 的高导热装置, 并包括一个蒸发端 428a及冷凝端 428b。 所述第二导热件 428 的冷凝端 428b设置在所述温控相变模块 426上,而蒸发端 428a伸入所述拒体 310内。
可以理解,所述第一导热件 424及第二导热件 428的蒸发端及冷凝端并不 是固定的, 其冷凝端及蒸发端是根据导热件两端的温度差而定义的, 比如, 温 度高的一端为蒸发端, 而温度低的一段则相应的为冷凝端。
所述第二热交换装置 430设置在所述 TEC模块 410的热端 414。 本实施 例中, 所述第二热交换装置 430包括蒸发端 432、 冷凝端 434以及设置在所述 第二热交换装置 430内用以在所述的蒸发端 432及冷凝端 434通过相变的方式 进行热交换的冷却媒质 436。
所述的蒸发端 432与所述 TEC模块 410的热端 414相邻接或者接触, 冷 凝端 434远离所述蒸发端 432。 本实施例中, 所述蒸发端 432穿置在所述 TEC 模块 410的导热板 416上。
为了进一步提高第二热交换装置 430与周围环境的热交换速率,可在所述 第二热交换装置 430上设置多个散热板 438。 所述散热板 438间隔均匀地设置 在所述蒸发端 432及冷凝端 434之间,用以增加所述第二热交换装置 430与周 围空间的接触面积,从而通过空气的自然对流来将第二热交换装置 430上的热 量带走。
所述第二热交换装置 430位于所述拒体 300的外侧, 并与所述拒体 300 的内部空间热隔绝。 所述保护罩 330将所述第二热交换装置 430收容于其中。
本实施例中所述第二热交换装置 430可以为热管, 热虹吸管, 蒸汽腔等高 导热装置。
本实施例提供的所述 TEC制冷装置 400通过采用可进行快速散热的第二 热交换装置 430来加快与所述 TEC模块 410热端 414之间的热交换, 从而热 交换速率, 同时不需要在所述 TEC模块 410的热端 414处设置风扇, 这样便 可节省能源, 同时降低噪音, 以达到绿色环保的目的。 此外, 通过所述第一热 交换装置 420的温控相变模块 426来存储一定热能或者冷能, 从而使机拒 300 内的温度能够保持在一定范围内, 以使 TEC制冷装置 400及使用该 TEC制冷 装置 400的电器装置 20能够在大温差环境中保持相对稳定的工作温度。
以上所述仅为本发明的较佳实施例, 并不用以限制本发明, 凡在本发明的 精神和原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的 保护范围之内。
