<strong>板式换热器</strong>特点主要从以下内容来分析</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.<strong>传热系数高</strong> 由于不同的波纹板相互倒置，构成复杂的流道，使流体在波纹板间流道内呈旋转三维流动，能在较低的雷诺数（一般Re=50~200）下产生紊流，所以传热系数高，一般认为是管壳式的3~5倍。<br/>　&nbsp; 2.<strong>对数平均温差大</strong>，末端温差小 在管壳式换热器中，两种流体分别在管程和壳程内流动，总体上是错流流动，对数平均温差修正系数小，而板式换热器多是并流或逆流流动方式，其修正系数也通常在0.95左右，此外，冷、热流体在板式换热器内的流动平行于换热面、无旁流，因此使得板式换热器的末端温差小，对水换热可低于1℃，而管壳式换热器一般为5℃.<br/>　 3.<strong>占地面积小</strong> <a href="http://www.njviex.com" target="_blank">板式换热器</a>结构紧凑，单位体积内的换热面积为管壳式的2~5倍，也不像管壳式那样要预留抽出管束的检修场所，因此实现同样的换热量，板式换热器占地面积约为管壳式换热器的1/5~1/10。<br/>　　d.容易改变换热面积或流程组合，只要增加或减少几张板，即可达到增加或减少换热面积的目的；改变板片排列或更换几张板片，即可达到所要求的流程组合，适应新的换热工况，而管壳式换热器的传热面积几乎不可能增加。<br/>　　e.重量轻 板式换热器的板片厚度仅为0.4~0.8mm，而管壳式换热器的换热管的厚度为2.0~2.5mm，管壳式的壳体比板式换热器的框架重得多，板式换热器一般只有管壳式重量的1/5左右。<br/>　　f. 价格低 采用相同材料，在相同换热面积下，<a href="http://www.njviex.com" target="_blank">板式换热器</a>价格比管壳式约低40%~60%。<br/>　　g. 制作方便 板式换热器的传热板是采用冲压加工，标准化程度高，并可大批生产，管壳式换热器一般采用手工制作。<br/>　　h. 容易清洗 框架式板式换热器只要松动压紧螺栓，即可松开板束，卸下板片进行机械清洗，这对需要经常清洗设备的换热过程十分方便。<br/>　　i. 热损失小 板式换热器只有传热板的外壳板暴露在大气中，因此散热损失可以忽略不计，也不需要保温措施。而管壳式换热器热损失大，需要隔热层。<br/>　　j. 容量较小 是管壳式换热器的10%~20%。<br/>　　k. 单位长度的压力损失大 由于传热面之间的间隙较小，传热面上有凹凸，因此比传统的光滑管的压力损失大。<br/>　　l. 不易结垢 由于内部充分湍动，所以不易结垢，其结垢系数仅为管壳式换热器的1/3~1/10.<br/>　　m. 工作压力不宜过大，介质温度不宜过高，有可能泄露 板式换热器采用密封垫密封，工作压力一般不宜超过2.5MPa，介质温度应在低于250℃以下，否则有可能泄露。<br/>　　n. 易堵塞 由于板片间通道很窄，一般只有2~5mm，当换热介质含有较大颗粒或纤维物质时，容易堵塞板间通道。</p>]]></description><category>产品中心</category><comments>http://www.njviex.com/zixun/post/165.html#comment</comments><wfw:commentRss>http://www.njviex.com/zixun/feed.asp?cmt=165</wfw:commentRss></item><item><title>板式换热器有那些组成</title><author>null@null.com (njviex)</author><link>http://www.njviex.com/zixun/post/164.html</link><pubDate>Thu, 11 Jun 2015 21:45:59 +0800</pubDate><guid>http://www.njviex.com/zixun/post/164.html</guid><description><![CDATA[<p><strong>板式换热器</strong>主要由框架和板片两大部分组成。<br/>板片由各种材料的制成的薄板用各种不同形式的磨具压成形状各异的波纹，并在板片的四个角上开有角孔，用于介质的流道。板片的周边及角孔处用橡胶垫片加以密封。<br/>框架由固定压紧板、活动压紧板、上下导杆和夹紧螺栓等构成。<br/><a href="http://www.njviex.com" target="_self">板式换热器</a>是将板片以叠加的形式装在固定压紧板、活动压紧板中间，然后用夹紧螺栓夹紧而成。</p><p>南京板式换热器咨询电话<strong><span style="color: rgb(85, 85, 85);">025-86535028/13705150429</span></strong></p>]]></description><category>产品中心</category><comments>http://www.njviex.com/zixun/post/164.html#comment</comments><wfw:commentRss>http://www.njviex.com/zixun/feed.asp?cmt=164</wfw:commentRss></item><item><title>等待的日子-南京板式换热器</title><author>null@null.com (njviex)</author><link>http://www.njviex.com/zixun/post/163.html</link><pubDate>Wed, 10 Jun 2015 10:50:21 +0800</pubDate><guid>http://www.njviex.com/zixun/post/163.html</guid><description><![CDATA[<p>&nbsp;南京板式换热器<strong>一直受大家的关注，而我们<a href="http://www.njviex.com" target="_blank">南京维克斯换热器</a>对大家的需求也是有求必应。我们为了做好每一个事项而努力着。 24小时咨询电话025-86535028/13705150429。</strong></p><p>板式换热器在各行各业都有应用，南京维克斯曾经服务过的行业：<span style="font-family: 微软雅黑;

&nbsp;<strong>板式换热器</strong>流型有逆流、顺流和混合流型 (既有逆流又有顺流 )。板式换热器在相同工况下，逆流时对数平均温差最大，顺流时最小，混合流型介于二者之问。提高板式换热器对数平均温差的方法为尽可能采用逆流或接近逆流的混合流型，尽可能提高热侧流体的温度，降低冷侧流体的温度。<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 另外，确定好进出口管位也可以提高板式换热器的性能。对于单流程布置的板式换热器，为检修方便，板式换热器流体进出口管应尽可能布置在板式换热器固定端板一侧。板式换热器介质的温差越大，流体的自然对流越强，形成的滞留带的影响越明显，因此<a href="http://www.njviex.com" target="_blank">板式换热器</a>介质进出口位置应按热流体上进下出，冷流体下进上出布置，以减小滞留带的影响，提高板式换热器传热效率。</p><p><a href="http://www.njviex.com" target="_blank">南京维克斯</a>换热设备有限公司<br/>电话：025-86558520 /86535028 <br/>传真：025-86534577<br/>地址：江苏南京市江宁区天元中路128号<br/>邮编：211100<br/>Email：<a href="mailto:viex9838@126.com">viex9838@126.com</a><br/>网址：http：//www.njviex.com</p><p>24小时售后服务热线：13705150429</p><p></p>]]></description><category>产品中心</category><comments>http://www.njviex.com/zixun/post/159.html#comment</comments><wfw:commentRss>http://www.njviex.com/zixun/feed.asp?cmt=159</wfw:commentRss></item></channel></rss>
