無菌換熱器
Aseptic Heat Exchanger
基本原理
Basic Principles
換熱器是熱流體的部分熱量傳遞給冷流體的設備，又稱為熱交換器。列管式換熱器由殼體、管束、管板、折流擋板和封頭組成。換熱器中流體的相對流向一般有順流和逆流兩種。順流時，入口處兩流體的溫差大，并沿傳熱表面逐漸減小。逆流時，沿傳熱表兩流體的溫差分布較均勻
Heat exchanger is a device that transfers part of heat from hot fluid to cold fluid, also known as heat exchanger. The tubular heat exchanger consists of shell, tube bundle, tube plate, baffle and head. The relative flow direction of fluid in heat exchanger generally has two kinds: downstream and countercurrent. The temperature difference between the two fluids at the inlet is the largest and decreases along the heat transfer surface. The temperature difference distribution of two fluids along the heat transfer meter is more uniform when countercurrent occurs.
