Description

一种模块式相变储能换热器 技术领域
本发明属于换热器领域，涉及相变换热装置，尤其是一种模块式相变储能换热器。
背景技术
换热器是在一个密闭容器中装有相变储能材料和贯穿其中的两套不同介质的管路，其中防冻液介质管路的两端分别从该容器的两侧伸出并且外接于太阳能集热器的进出水管，循环水管路在的两端也从容器的两侧伸出且和散热装置相连。在白天利用太阳能集热板收集热量，并传递给容器中的相变储能材料，进而使散热装置里的水升温供人们在白天取暖，且相变储能材料有保持室内温度恒定的作用。而在夜晚或者阴天的时候，关闭防冻液介质管路的循环，使得容器内相变储能材料将白天储存的过剩的太阳能释放出来并将热量传递给散热器供人们取暖。
现有的相变储能换热器多采用隔板将介质隔开，如专利CN206235227U、CN107747813A、CN206339141U，这种结构设计的缺点是:1、接口多容易漏液；2、装置加工难度大；3、储能量受到装置大小的限制。
发明内容
本发明的目的在于克服现有技术的不足之处，提供一种加工简单、接口少漏液率低、可以将多个拼装使用的模块式相变储能换热器。
本发明解决技术问题所采用的技术方案是：

而且，在箱体内表面及箱盖内侧均制有用于固定防冻液输液管及循环水输水管的管卡槽。
而且，所述换热器多个串联，相邻的两个换热器间其中一个换热器的防冻液出液管接口、循环水出水管接口分别与另一个换热器的防冻液进液管接口、循环水进水管接口通过密封管 接头连接。
而且，在换热器箱体的外壁制有使两个换热器箱体能够连接在一起的拼插构件。
而且，所述的拼插构件为在箱体的两侧外壁分别制有卡槽及卡块。
而且，两防冻液输液管平行，且每一根呈蛇形弯曲；两循环水输水管平行，且每一根均呈蛇形弯曲。
而且，防冻液进液腔与防冻液出液腔呈对角设置；循环水进水腔与循环水出水腔呈对角设置。
而且，所述箱体、箱盖、接口盒采用高分子材料注塑加工制成。
