【技术实现步骤摘要】
一种换热器
本技术涉及一种换热器。具体说，是用来对液体介质进行加热的盘管式换热器。尤其适用于机械密封辅助系统中对机械密封腔内的缓冲液进行冷却。
技术介绍
在机械密封辅助系统中，常采用盘管式换热器来对机械密封腔内的缓冲液进行冷却，使缓冲液的温度满足工艺条件的需要。传统的盘管式换热器包括一个圆筒状外壳，圆筒状外壳的上下端分别设置有顶盖和底盖，顶盖和底盖上均加工有管孔。顶盖和外壳上部一侧分别设置有冷媒出口和冷媒进口。外壳内设置有盘管，盘管两端分别穿过顶盖和底盖的相应管孔之外。所述盘管是用铜管盘绕而成的直筒状盘管，直筒状盘管的邻圈间均有间隙。由于直筒状盘管的邻圈间均有间隙，冷媒从冷媒进口进入壳体后穿过邻圈间的间隙后，直接从冷媒出口排出，冷媒在筒体内停留的时间短、换热效率低。
技术实现思路
本技术要解决的问题是提供一种换热器。采用这种换热器，可延长冷媒在筒体内的停留时间，提高换热效率。本技术要解决的上述问题由以下技术方案实现：本技术的换热器包括外壳，外壳的上下端分别有顶盖和底盖，顶盖和底盖上均有管孔。顶盖和外壳上部一侧分别有冷媒出口和冷媒进口。外壳内有盘管，盘管两端分别穿过顶盖和底盖的相应管孔之外。所本文档来自技高网...
