具体实施方式：
以下结合附图和实施例对本发明作进一步地说明。
本发明换热器的槽片加工方法， 其包括下述步骤： 用管道折叠环绕法在金 属板一侧设有至少一条连通的凹通道， 而另一侧相应地形成有连通的压焊通道。
所述的管道折叠环绕法指的是： 将一根管道相对折叠后， 管与管对齐， 其 管与管之间留有一定间距， 再环形平 （盘） 绕。 这种方式制作的换热器槽片有 两个好处： 1、 其进出口可以位于一侧， 有利于设计和安装； 2、 流体沿通道进 去， 能够实现从盘片外围到中心再从中心到外围的两个过程（见图 2和图 3中虚 线部分）， 其不但流程较长， 而且可以使流体受到两次加热的过程。 本发明中的 换热器的槽片正是依据这一原理设计的， 从上述描述及图可以看出， 在本发明 中， 管道折叠环绕法指的是如图 2和图 3虚线部分所示出的盘绕曲线， 本发明 的换热器槽片上的凹通道或压焊通道的中心线就是上述的盘绕曲线。
如图 1所示， 为一加工好的换热器槽片的剖视示意图。 图 1中凹通道 11及 其另一侧的压焊通道可釆用冲压或拉深等方式加工。 其中， 压焊通道是用来将 该换热器槽片压焊到金属板上或另一换热器槽片上的， 并且其可以增加换热槽 片的受热面积。
上述凹通道 11 以及压焊通道 12的横截面的形状可根据客户的需要以及机 加工的需要来选定， 可以为弧形、 半圓形、 长方形、 梯形、 异形或三角形等。
作为本发明更进一步地改进， 上述的凹通道 11是釆用下述步骤加工的： 1、 按管道折叠环绕法制作的凹凸模具， （也就是制作具有管道环绕曲线的凹凸模 具）； 2、 利用凹凸模具对金属薄板冲压或拉深至预定尺寸， 从而在金属板上形 成凹通道和压焊通道。 这种作业方式有利于产品的大批量生产， 且产品一致性 好， 成品率高。 上述的金属薄板的厚度可以根据金属薄板的材质、 IHJ通道的曲 率和机加工方式来选择。 上述的预定尺寸指的是凹通道的宽度和深度， 这一点 决定于金属薄板的材质和加工方法等方面。
本发明中的换热器槽片是按上述方法制作加工而成的， 这里不再赘述。 本发明的换热器是釆用上述的换热器槽片制成， 如图 5 所示， 其可以由两 块凹通道 1 1相对重合设置的换热器槽片组成， 其中， 所述的相对重合设置是指 一个换热器槽片为另一个的镜像， 也就是说其中一个的凹通道曲线为另外一个 换热器槽片翻转 180° 后的曲线重合， 如图 6和图 7中所示， 其中左右两个换热 器槽片互为镜像。 这样， 两相对重合设置的凹通道 1 1合在一起形成连通的流体 通道 3 ;在换热器槽片的侧面设有与流体通道连通的流体进口 31和流体出口 32。 在制作时， 将两个凹通道相对重合设置的换热器槽片上下合好后， 位于上方的 换热器槽片的相邻两 iHJ通道之间的缝隙 （即压焊通道的底） 与其下方的换热器 槽片的相邻两凹通道之间的缝隙也重叠在一起， 这时釆用压焊的方式对两个压 焊通道进行压焊， 从而使上下两个压焊通道的底被焊接在一起， 从而形成隔离 墙， 而所述的 IHJ通道 1 1则形成一个周侧封闭的流体通道 3。
本发明的换热器也可由一块换热器槽片以及在其凹通道一侧设置的金属板 2盖封压焊制成，如图 4所示，所述的 IHJ通道与金属盖板一起形成一流体通道 3 , 所述的流体通道 3在换热器一侧形成有与流体通道连通的流体进口 31和流体出 口 32。 其加工生产的方法同上。
上述的换热器还可以这样制作： 制作上盖板和下盖板， 在上下盖板之间按 管道折叠环绕法设置金属板条作隔离墙， 用以在上盖板和下盖板之间形成至少 一流体通道。
本发明的热水器， 是釆用上述的换热器制成的， 包括一个内径与换热器相 适配筒体， 所述筒体的筒口朝下， 在所述的筒体 4内顶部设有至少一个换热器， 换热器的流体进口与流体出口通过管道连接于筒体 4外， 在筒体 4的周侧与换 热器槽片压焊通道 12相对应的位置设有出气口。
图 8所示为本发明热水器的另一实施例的结构示意图。 如图 8所示， 所述 的热水器是釆用两个换热器的相背设置而成， 其中， 下换热器大体中部的位置 设有通孔 5 , 用以使炉灶中的热量通过该通孔流动到压焊通道 12中， 所述的通 孔可以位于两相邻流体通道中间的缝隙处 , 但其不与流体通道相连通； 在筒体 的周侧与换热器下压焊通道相对应的位置设有出气口。 这样， 炉灶中的热气通 过中心通孔 21进入到压焊通道中， 然后顺着压焊通道的盘绕曲线向外流动， 并 通过筒体周侧的通气孔流出。 在这个过程中， 换热器槽片能够将压焊通道中的 热量传递给流体通道中， 从而使流体通道中的流体被加热。 实际使用时， 上下 两个换热器可以连接成串联方式， 即上换热器的出水口与下换热器的进水口相 连通； 也可以连接成并联方式， 即两个换热器的进水口与进水口相连通， 出水 口与出水口相连通。 当然， 依据上述原理还可以根据需要设置由更多个换热器 叠置而成的热水器。
上述的换热器还能制成电磁热水器， 即， 上述的换热器釆用导磁金属材料 制作， 如铁等； 在所述的至少一个换热器的至少一侧设有电磁线圈， 所述的电 磁线圈与换热器之间设有绝缘材料；通以电流后的电磁线圈可产生磁场， 磁场在 导磁金属材料制成的换热器中将产生涡流， 使换热器发热， 从而使换热器流体 通道中的流体被力口热。 综上， 本发明适用于农村家庭、 乡镇、 街道、 居民、 机关、 学校、 烧柴烧 炭以及有自来水的地方均可使用， 本项发明主要特点是， 管路环绕密集， 水环 流加热水温直线上升， 煮饭后余火方可烧热水。
