申请人在 1982年获得授权的英国专利文献（GB2119496 )中提出 了一种人工制冷滑冰场分配制冷剂的集管装置，其须要加工数百个三 通元件， 用于循环排管与制冷集管的连接， 每个三通元件内均须设置 一个弯折成 90度的供液喷管， 并在供液喷管朝向供液排管的一端套 装一个环形隔板， 将三通元件的内腔与供液排管隔开； 加工时， 须在 三通元件上用车床切削一个凹槽，用于固定环形隔板，如此加工过程， 相对较为复杂， 一是在三通元件内口切削凹槽加工难度较大， 且不够 精准， 90度的供液喷管须要冷煨加工成型， 然而在煨制加工的过程 中很容易造成喷管的内径变形以至断面缩小， 影响喷液均匀度； 二是 三通元件的环形隔板与三通本体以及喷管两个圆形焊缝的焊接操作 难度较大，而且为了美观在烧焊后还须要用车床第二次切削焊缝以整 说 明 书
型。
此外， 三通元件经过多次切削与焊接热加工， 其材质容易变质变 脆， 在查漏工序时容易因为材质有变化而渗漏制冷剂； 又、 三通元件 的出液与回气端口距制冰集管的距离很小不易烧焊，也很难使用焊接 夹具， 因而不利于焊接施工； 再者， 三通元件具有一定的高度， 使得 整个集管制冰装置的高度较高，致使套合集管最下部的保温材料层厚 度较薄容易造成套合集管对应钢筋混凝土的下部传冷而聚集凝露。 发明内容
针对现有技术的不足，本发明的目的旨在于提供一种人工制冷滑 冰场用套合式集管制冷装置， 其加工简单， 施工方便， 支管回路长度 缩短一半， 运行更为省电， 且具有更为均勾的制冰效果。

在弯头 23的下端开口与制冷供液集管 1之间连接有一液态制冷 剂喷管 1 1 , 其与弯头 23下端管口同轴， 上端穿过回气集管 2管壁上 预设的通孔导通并焊封在弯头 23内， 下端则穿过制冷供液集管 1的 管壁与制冷供液集管 1的管腔导通。 在回气集管 2上位于弯头 22下 端管口所围成的范围内开设有一回气孔 21。 上述循环排管一端为供 液排管 6 , 另一端为回气排管 7 , 与弯头 23上端管口焊接的即为供液 排管 6 , 与弯头 22上端管口连接的即为回气排管 7; 上述结构组成一 组制冷循环单元，拒型整体式制冰机组 3工作所产生的低温液体通过 供液干管 41被输送至制冷供液集管 1内， 再由小口径的液态制冷剂 喷管 11喷射送至供液排管 6内与滑冰场的结水地面进行热交换， 吸 热汽化成为气体， 然后经过回气排管 7 , 经由回气孔 21、 回气集管 2, 回气干管 42被吸回拒型整体式制冰机组 3进行再一次制冷循环。
上述结构构成一组循环单元， 上述弯头 22、 23分别位于回气集 管 2的左侧， 并且多个弯头 22、 23在回气集管 2的左侧沿其长度方 向排列， 而对应的， 在循环集管 2的右侧设置有多个弯头 22、、 23 \ 其中弯头 22、内设有回气孔 21、， 而弯头 23、内则设置有与液态制冷 说 明 书
