一种大热容量的换热器及使用该换热器的冷冻离心机
摘要：
本实用新型涉及一种热量交换器，特别涉及一种能提供大热容量的换热器；一种换热器，包括具有腔体功能的内胆和盘管，其特征在于，所述换热器还包括一保温层，所述保温层与内胆形成一封闭空间，所述盘管位于所述封闭空间中，且与所述内胆形成间隙的嵌套，在所述封闭空间中填充有容热导热材料。本实用新型采用内胆和保温层形成的空间容纳盘管和容热导热材料，使得盘管与内胆之间不必紧贴也能有较好的换热效率，这样在制作所述换热器时，只需将内胆嵌套进所述事先绕制好的盘管中，不必在内胆外壁上强行紧贴绕制盘管，简化了生产工艺、提高了生产效率；另外由于内胆和保温层形成的空间中填充了容热导热材料增强了单纯盘管的热容量，增强了换热效果。
摘要（英）：

The utility model relates to a heat exchanger, in particular to a large heat capacity heat exchanger, which comprises an inner bag with cavity function, a pipe coil and characteristically, an insulation layer, wherein, the insulation layer and the inner bag form an enclosed space; the pipe coil is positioned in the enclosed space and forms an intervallic nesting; heat holding conducting material is filled into the enclosed space. The utility model has the advantages of that: containing the pipe coil and the heat holding conducting material in the enclosed space formed by the insulation layer and the inner bag makes the space between the pipe coil and the inner bag had high heat exchange efficiency without clinging together, thereby, during making the heat exchanger, the inner bag needs only to be nested into the pipe coil winded up in advance without clinging and winding the pipe coil on the outer wall, simplifying manufacture process and increasing production efficiency; in addition, the heat holding conducting material filled in the enclosed space formed by the insulation layer and the inner bag increases heat capacity of single pipe coil and heat exchange effect.
