如图1至3所示，本发明一实施例的试剂仓102，包括：试剂仓本体70、及设置在试剂仓本体70底部的散热装置100。
本实施例的试剂仓本体70侧面设置有保温层。本实施例的试剂仓本体70的保温 层为保温棉包裹形成。优选的，试剂仓本体70侧部的保温层通过两层保温棉缠绕形成。本实施例的散热装置100为上述散热装置，在此不再赘述。
本发明通过将试剂仓本体70底部设置散热装置100，散热装置100的三个散热器40首尾通过风道串联。在第一个散热器40的端部布置蜗牛风扇作为送风装置80对着散热器40的散热鳍片44吹风，吹风方向与散热鳍片44平行。在第三个散热器40的尾部布置另一个蜗牛风扇作为抽风装置90进行抽风，抽风方向平行或近平行于散热鳍片44，通过这种方式使得气流快速将散热鳍片44表面的热量带走。本实施例的近平行状态指平行设置，偏差不超过30°。优选的，平行偏差不超过15°。
本实施例中形成风道的串联拼接罩壳60与散热器鳍片44间距4-6mm，优选的间距约5mm，提高气流的层流水平，进而提高散热鳍片44的散热效率。
本实施例的试剂仓本体70侧面通过两层保温棉缠绕包裹形成保温层进行保温。整机制冷工作时，先开启蜗牛风扇，再打开制冷片，使得制冷片22开始工作时热端的热量可以第一时间被导走，提高试剂仓制冷速度。制冷片22热端与散热器40上表面即散热接触部42贴合，在散热器40上表面即散热接触部42开设冷片凹槽422，冷片凹槽422深度不高于制冷片22的厚度或高度如0.5mm左右的深凹槽，将制冷片22嵌入其中。
本发明的试剂仓102的试剂仓本体70外圈通过两层10mm的保温棉包裹，用以对仓体的保温。在试剂仓本体70底部布置三个制冷模块20，制冷模块20的制冷片22的热端与鳍片式散热器40直接贴合，三个散热器40通过罩壳依次连接形成依次首尾相连的风道，在第一个散热器40端部布置作为送风装置80的蜗牛风扇对着散热器40吹风，吹风方向与散热鳍片44方向平行。
第三个散热器40尾部布置有作为抽风装置90的蜗牛风扇进行抽风。形成风道的罩壳60与散热鳍片44保持约5mm间隙，气流方向与散热鳍片方向平行，可以迅速带走散热鳍片表面的热量，提高制冷效率。同时，该发明仅使用两个蜗牛风扇，在相同负压的情况下，蜗牛风扇的噪音要比轴流风扇低5dB以上，可以实现更低的整体噪音水平，在提高试剂仓的散热器40的散热效率的同时降低噪声。
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本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。
