上等冷却器是换热设备的一类，用以冷却流体。通常用水或空气为冷却剂以除去热量。有间壁式冷却器、喷淋式冷却器、夹套式冷却器和蛇管式冷却器等。下面乾锐锋液压简单介绍一下冷却器的日常维护。

冷却器因冷却水大多数含有钙、镁离子和酸式碳酸盐。当冷却水流经金属表面时，有碳酸盐的生成。另外，溶解在冷却水中的氧还会造成金属腐蚀，形成铁锈。由于锈垢的产生，换热效果下降。严重时不得不在壳体外喷淋冷却水，结垢严重时会堵塞管子，使换热效果失去作用。研究的数据显示水垢沉积物对热传输的损失影响巨大，随着沉积物的增加会造成能源费用的加大，节约能源、延长设备的使用寿命，同时节约生产时间和费用。

长期以来传统的清洗方式如机械方法（刮、刷）、高压水、化学清洗(酸洗)等在对设备清洗时出现很多问题：不能彻底**水垢等沉积物，酸液对设备造成腐蚀形成漏洞，残留的酸对材质产生二次腐蚀或垢下腐蚀，*终导致更换设备，此外，清洗废液有毒，需要大量资金进行废水处理。

A、由于风冷和传统水冷的工作原理及结构不同，但国内厂家常按照以往水冷的安装方法接入系统，这是不提倡的。像日本、德国等外企绝大多数采用独立循环的冷却方式，这样与系统区隔开来，不存在漏油问题。当风冷接入回路中时，安装旁通回路是必须的，这样方可以避免机器工作中出现故障时保护好散热器，在机器故障：比如电**阀、突然制动、电路控制失效等状况下，回油脉冲压力瞬间升高释放，是造成散热器爆裂的主要原因。另外，旁通回路必须独立回油箱，若与系统回油管合并，亦为失效的安装方法。

 B、安全系数问题、必须确定实际回油流量，这很重要，实际回油流量并不等于泵的工作流量(请联系无锡乾锐锋液压科技销售部)。比如：实际回油流量100L/min，那么，选择散热器时应乘以安全系数2，即100*2=200L/min。没有安全系数，又不装旁通回路，一旦机器故障，安全无法保证。

 C、不主张在散热器的出油口安装过滤器，这样做的缺点很多，比如：不定期清理或没有及时清理，回油阻力不断增大，依据国内外客户的经验，往往导致散热器爆裂。过滤器应装在散热器进口前部。
