Description

大热容量不间断工作的热交换器
技术领域
本发明涉及制冷技术领域， 适用于 ¾冰箱、 电冰柜、 低温箱、 冷 饮机、冰激淋机及间断式工作的小型制冷机等制冷设备中的大热容量 不间断工作的热交换器。
发明背景
目前，诸如电冰箱等制冷机中的热交换器， 比如冷凝器或蒸发器， 受到耗材少、轻巧、廉价等传统设计思想的约束， 主要用金属材料制 成，包括流通制冷工质的工作管及与工作管相连的散热片， 这种换热 器无论是冷凝器， 还是蒸发器， 其热容量均很小， 均为间断式工作， 通常电冰箱开机率在 35— 45%， 工作机制是制冷机停机时， 热交换 器也停止工作， 再加上热交换过程中有空气自然对流换热，所以换热 温差大， 存在着制冷机的熵增大、 电耗大等缺陷。
发明内容
本发明目的在于提供一种大热容量不间断工作的热交换器，该热 交换器增加了与制冷工作管并联的蓄热或蓄冷管，蓄热或蓄冷管中充 填蓄热或蓄冷物质，这种热交换器利用制冷机停机至开机之间的一段 时间换热的潜能，用蓄冷或蓄热物质分流换热器开机时的热流量，使 制冷机在停机时， 热交换器仍工作， 克服了传统间断式制冷机存在的 上述诸多缺陷。
本发明的实施方案如下：
本发明提供的大热容量不间断工作的热交换器，包括流通制冷工 质的工作管及与工作管相连的散热片，其特征在于： 工作管或并联有 蓄热或蓄冷管， 蓄热或蓄冷管中充填 蓄热或蓄冷物质； 或于工作管 与散热片之间充填 蓄热或蓄冷物质； 对于用外壳散热的换热器， 本 发明特征是在工作管与等效于散热作用的外壳之间充填蓄热或蓄冷 物质；
所述的蓄热或蓄冷物质可以是相变温度为 50至 -90C。的相变材 料或显热材料，包括正烷类， 脂肪酸类及其衍生物， 或为无机盐水溶 液以及酚类、 苯类、 醇类及其衍生物有机溶液的稀释电解液， 比如- 可为氯化钠、 氯化钙水溶液或乙二醇， 乙醇和丙二醇有机试剂溶液， 还可为四氯化碳、邻二氯化苯， 苯甲醇、邻甲苯胺及二甲基乙酰胺有 机物质的溶剂， 也可为制冷剂 R30， 这些蓄热或蓄冷物质可以单独使 用， 也可配比使用。 在制冷机中， 以电冰箱为例， 电冰箱中的冷凝器和蒸发器使用本 发明提供的大热容量不间断工作的热交换器结构，其冷凝器便成了大 热容量不间断工作的冷凝器，蒸发器便成了大热量不间断工作的蒸发 器。 由于本发明的热交换器增加了与制冷工作管并联的蓄热或蓄冷 管， 蓄热或蓄冷管中充填蓄热或蓄冷物质，合理地利用了制冷机停机 至开机之间一段时间换热的潜能，即用蓄热或蓄冷物质分流热交换器 幵机时的热流量， 使制冷机在停机时， 热交换器仍工作， 实现小温差 换热，缩短制冷机工作温区， 降低压比，减少熵增，大大地降低能耗， 延长压缩机和制冷机的寿命。

具体实施例
下面结构附图及实施例进一步描述本发明：
附图 1为电冰箱中冷凝器和蒸发器采用本发明的结构示意图。 电冰箱的冷凝器及蒸发器采用本发明的结构，便成了大热容量不 间断工作的冷凝器和大热容量不间断工作的蒸发器， 由图知，这里的 工作管 1实际上是冷凝器中的冷凝管， 也是蒸发器中蒸发管，其结构 为工作管 1由外壳 3包裹， 之间充填蓄热或蓄冷物质 3 , 4为灌装蓄 热或蓄冷物质 3的进料口。
在本实施例中， 蓄热或蓄冷物质若用相变材料， 其相变温度为 摄氏 50至一 90°C， 例如正垸类、 脂肪酸类及其衍生物； 若用显热材 料， 可用无机盐水溶液以及酚类、 苯类、 醇类及其衍生物的有机溶剂 稀释电解液。 此时， 水溶液需要加入祛氧剂、 防腐剂、 缓腐剂和能够 提高水传热性能的醇类等化学试剂。
外壳 3起着散热作用， 其表面有强化换热层结构； 外形分为异 型、 冲压型及预应力肋化型； 材料可选用金属或良导热塑料。 工作管 1与外壳 3之间要求有良好的热连接，二者间可以焊接或 用导热胶粘接或用铝箔胶带粘接， 也可以用冷压法机械连接。
冷凝器传热计算公式： Q= S * Κ · Δ Τ
式中： Q 热负荷 Δ Τ 冷凝器与室温之间的温差
S 传热面积 Κ 传热系数
倘若 S和 Κ值不变， 则因热负荷 Q降低， 则温差 也随之降 低， 以致整个制冷系统熵增下降。 于是该冷凝器可产生节能效果。 若 制冷机停机时间在整个制冷周期所占时段愈长， 则节能效果愈明显。
本发明的工作机理：
制冷机中， 以电冰箱为例， 电冰箱通常包括压縮机、 冷凝器、 节 流毛细管、 蒸发器和制冷工质； 在蒸发器里工作介质由液态变气态， 吸热而制冷， 冷凝器使蒸气冷凝变为液体， 同时放出冷凝热。
当制冷系统工作时， 制冷机运转，采用本发明结构的冷凝器的工 作管（也称冷凝管）放出冷凝热， 其中一部分传给与冷凝管热连接的 外壳， 并传给空气， 另一部分传给与冷凝管中的蓄热物质。倘若蓄热 物质采用相变材料， 则其因受热而由固态变液态， 吸收冷凝管传来的 冷凝潜热； 倘若蓄热物质是显热材料， 则吸热而自身升温。
当制冷机停机时， 冷凝管亦停止工作， 而蓄热物质却开始放热， 使冷凝器继续散热。这时， 若是相变材料， 则其由液态变为固态释放 潜热； 若是显热材料， 则其因放热而自身降温， 直到制冷机的下一个 工作周期重新启动为止。 虽然表面看来， 冷凝管半个周期放热， 半个 周期不工作， 但在制冷机停机时， 蓄热物质放热仍工作。 于是本发明 结构的冷凝器等效于全工作周期散热而不间断地工作。
同理， 电冰箱中的蒸发器由于采用本发明结构， 当制冷机工作 运转时， 蒸发器的工作管吸收蒸发热，其中一部分通过外壳吸收空气 中的热量而制冷， 另一部分吸收蓄冷物质的热量。若蓄冷物质采用相 变材料， 则因吸热由液态变固态， 吸收蒸发管传来的冷量； 若蓄冷物 质采用显热材料， 则闲吸收冷量自身降温， 当制冷机停机时， 蒸发器 的工作管停止工作， 而蓄冷物质却开始吸热制冷， 使蒸发器继续吸 热， 这时， 蓄冷物质若是相变材料， 则由固态变为液态,吸热制冷， 若是显热材料， 则因吸热而自身升温， 直至制冷机重新启动为止。于 是本发明结构的蒸发器等效于全工作周期吸热而不间断地工作。
附图 2为屯冰箱屮内藏式冷凝器或蒸发器采用本发明的结构示 意图， 此吋的冷凝器便成了大热容量不间断工作的冷凝器， 蒸发器便 成了大热容量不间断工作的蒸发器。 其冷凝器包括工作管 1 (也称冷 凝管） 、 蓄热物质 2、 外壳 3、 导热胶 5、 铝箔胶带 6、 内壳 7和泡沫 塑料保温层 8。 蛇形工作管 1用导热胶 5粘结在外壳 3上， 工作管 1 各段间再用铝箔胶带 6粘接， 使冷凝管 1、 外壳 3铝铂胶带 6三者成 为一体： 外壳 3的内壳 7仰放， 并注入蓄热物质水溶液， 再将粘好的 工作管外壳 3反扣其上， 并沿接缝把外壳 3和内壳 7热焊在一起； 最 后外壳 3上加装泡沬塑料保温层 8。
