Description

一种热泵热水器水箱底部换热器
技术领域
本发明涉及一种热泵热水器的换热装置, 尤其涉及热泵热水器水箱底部换热器, 属于热水器技术领域。 背景技术
随着环保意识的增强, 符合绿色、 低碳的环保主题的热泵热水器越来越多应用到 生产生活中。 为此, 如何提高热泵的能效比成为关注的焦点。 而解决该问题, 从热泵热 水器工作过程中的水温分层来看, 水箱底部水温相对于上部水温低, 如何让热泵的冷凝 器更多地置于水箱的底部,对降低热泵系统的冷凝温度,提高热泵的性能系数至关重要。
现在市场上大多数热泵热水器的冷凝器将换热金属管缠绕在水箱的外表面, 有的 虽然部分缠绕在底部 (参见申请号为 200920050386. 1 的中国专利申请) , 但不仅由于 水箱底部多呈球冠状因此缠绕工艺复杂, 而且难以保证金属管与水箱表面的紧密贴合, 影响热交换效率。 发明内容
本发明的目的在于: 针对上述现有技术存在的缺点, 提出一种便于制造并且换热 效率高的热泵热水器水箱底部换热器。
为了达到上述目的, 本发明的热泵热水器水箱底部换热器包括与水箱底板形状相 吻合的金属基板, 所述基板上贴合固定形状与之相配的金属附着板, 至少所述金属基板 和所述附着板之一具有由进口延伸至出口的迂回隆筋,所述迂回隆筋的内表面与相邻板 (即相邻的金属基板或相邻的金属附着板)的对应表面之间形成由所述进口通往出口的 流道。
具体实施时, 所述金属基板可以附着固定在水箱底板上, 也可以直接作为水箱底 板。
实现本发明的制造方法主要步骤为: 将金属附着板按与水箱底板相吻合的形状冲 压成形; 将成形后的金属附着板与水箱底板贴合, 两者之间除预定迂回隆筋处外涂敷有 悍接剂; 将贴合在一起的金属附着板和水箱底板升温使悍接剂熔化后, 将金属附着板和 水箱底板悍接在一起;将悍接后的金属附着板和水箱底板放入具有与迂回隆筋相配迂回 凹槽的成形模具中加热; 从进口处注入压縮空气, 使金属附着板和水箱底板之间未悍接 的预定迂回隆筋部位被吹胀形成通往出口的迂回流道。 因此本发明切实可行。
由于本发明通过压悍或者紧密贴合使换热器附着在水箱底部, 因此充分利用了水 箱底部的整个换热面积, 有效提高了换热效率。 附图说明
下面结合附图对本发明作进一步的说明。
图 1为本发明实施例一的结构示意图。
图 2为本发明实施例二的结构示意图。
图 3为本发明实施例三的结构示意图。
图 4为本发明实施例一的立体结构示意图。 具体实施方式

组装时, 本换热器嵌入热泵热水器水箱底部, 与热水器水箱底板悍接固连。 根据 需要, 该换热器还可以与热泵系统中已有的水箱侧壁换热器或水箱内置换热器组成双级 复合式冷凝器, 进一步增加换热面积, 扩大该换热器的使用范围。
实践证明, 采用本实施例的热交换器后, 与单纯的水箱侧壁设置换热器或者底部 仅缠绕几根铜管相比, 在同等测试条件下, 可有效降低热泵系统的冷凝温度, 降低热泵 系统消耗功率, 从而提高了热泵系统的能效, 并为环保节能做出贡献。
实施例二
本实施例的热泵热水器水箱底部换热器如图 2所示, 与实施例一的区别是, 金属 基板 1呈凹面球冠状。 实施例三
