背景技术
化学发光设备中需要使用试剂仓来存储放置试剂，在测试过程中通过加样针提供试剂与样本反应。为保证试剂的活性，使其不变质，试剂仓内部要求温度控制在2～8℃，因此需要制冷装置来对试剂仓进行制冷。
中国专利文献108226462A公开了一种制冷效果好的免疫分析仪试剂仓，其通过在试剂仓底部安装半导体制冷片(帕尔贴)直接给试剂仓的底座制冷，底座给仓内空气制冷，从而满足2～8℃的要求。由于试剂仓盖上需要开设吸样孔，且经常需要打开仓盖装载试剂，从而使外部的热空气进入仓内，热空气遇到温度低的仓壁或者试剂盒外壁，会产生冷凝水。其危害有：内部元件损坏的风险增大；试剂盒外壁冷凝水会造成用户操作不便，用户体验差；积水覆盖在仓壁和试剂盒表面，影响换热效率。

半导体制冷器2，固定在所述制冷盒1的外壁上，通电时能够对所述制冷盒1进行制冷；
所述制冷盒1通过管道、风机4与试剂仓连通；
所述风机4出风口与试剂仓9连接，以使所述风机4的出风通入到试剂仓9内。
如图1和2所示，风机4从制冷盒1内部抽取冷空气送入试剂仓9内部，试剂仓9内部的空气再循环进入制冷盒1中进一步冷却，降低温度。如此进行内部空气的循环，实现试剂仓9内部空气的制冷；风机4出风口对准试剂仓9内部进行吹气，仓内形成一定的压力，可防止外部环境空气的进入；使得外部的热空气无法进入试剂仓9内，从制冷盒1中抽出的冷空气的温度比试剂仓9内温度低，且整个系统内的空气在不断循环流动，因此试剂仓9内不易形成冷凝水。
优选地，所述空腔内设置若干平行的散热片11，将所述制冷盒1与管道连接的进口和出口的中线进行连线，所述连线与所述散热片11平行，通过散热片11加强热交换效果。
优选地，所述半导体制冷器2设置在所述制冷盒1底部，以便于安装。
优选地，所述半导体制冷器2外壁设置有风扇3，通过风扇3加强空气流动，使所述半导体制冷器2内的空气快速冷却。
优选地，所述半导体制冷器2底部的外壁设置有若干平行的散热鳍片21，所述散热鳍片21的设置方向与所述风扇3产生的风力方向平行。散热鳍片21为若干平行鳍片结构，增加空气与制冷板的热交换面积，制冷盒1内设置散热片11，空气从散热片11处流过时，能够更快地进行热交换，制冷盒1外表面也包裹保温材料；
如图3所示，风扇3采用侧流风向与散热鳍片一致吹风的方式进行散热，这种吹风方式，风量大、风压强，散热效率高。
优选地，所述半导体制冷器2的冷端与制冷盒1连接接触，热端与散热鳍片21连接接触，且接触面涂覆有导热硅脂。
试剂仓9、风机4、制冷盒1之间采用管道连接，管道外表面均需包裹保温材料，降低冷空气与外部环境的热交换；
半导体制冷器2的冷端与制冷盒1连接接触，热端与散热鳍片21连接接触，为保证良好的热传导性能，接触面需增加导热硅脂或导热垫等；
制冷盒1与散热鳍片21之间需增加隔热棉23，防止冷热端相互影响；
实施例2
本实施例提供一种试剂仓，如图4所示，包括试剂仓本体和盖装在试剂仓本体顶部的盖体92，所述试剂仓本体与实施例1所述消除冷凝水的试剂仓制冷结构连接，所述试剂仓本体与所述盖体92之间设置有密封圈，所述试剂仓本体上有定位凸起91以使所述盖体92的吸样孔对准所述试剂仓9的进风口。所述试剂仓本体与所述盖体92之间设置有密封圈降低空气从试剂仓本体与所述盖体92间隙流过的量，同时吸样孔93对准并靠近试剂仓9的进风口，从风机吹入的气体能够直接从吸样孔93流出。
所述定位凸起91位于所述试剂仓9内壁且位于进风口的上方，盖体92内侧具有与定位凸起91配合的凹槽，以方便对盖体92的定位。
所述盖体92的内壁位于吸样孔93处设置有硅胶管道93，所述硅胶管道93的开口朝向试剂仓9的进风口，这样能够更进一步将从试剂仓9的进风口引导而从吸样孔93流出，同时，软质的硅胶在风力较大时，能够形成一定的形变，缩小硅胶管道93的直径，降低从吸样孔93流出的冷空气的量，提高制冷效果。吸样针伸 入时，柔软的硅胶管道93也不会妨碍吸样针的伸入。
以上述依据本申请的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项申请技术思想的范围内，进行多样的变更以及修改。本项申请的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
