Description
As a traditional type of heat exchange equipment, shell-and-tube heat exchanger has been applied for ages. It has been extensively applied in many industrial departments, especially in such industries as chemical engineering, petroleum and energy source. Shell-and-tube heat exchanger is composed of many tubes which constitute a tube bundle that serves as the heat transfer surface of heat exchanger. It is hereby also known as tubular heat exchanger.
Features
1, Simple structure, easy manufacturing
2, Large processing quantity (1-2, 000m³ /h)
3, Extensive material selection (carbon steel, stainless steel, copper or other metals)
4, Stable and reliable operating state
5, Strong adaptability (applicable to almost all industries)
6, Adaptability to high temperature and pressure (≤ 800° C; ≤ 6.0Mpa)
Theory and Application:
Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls, either from tube side to shell side or vice versa. The fluids can be either liquids or gases on either the shell or the tube side. In order to transfer heat efficiently, a large heat transfer area should be used, leading to the use of many tubes. In this way, waste heat can be put to use. This is an efficient way to conserve energy.
Shell and tube heat exchanger design:
Counter current heat exchangers are most efficient because they allow the highest log mean temperature difference between the hot and cold streams. Many companies however do not use single pass heat exchangers because they can break easily in addition to being more expensive to build. Often multiple heat exchangers can be used to simulate the counter current flow of a single large exchanger.
Applications and uses:
1.cooling of hydraulic fluid and oil in engines, transmissions and hydraulic power packs
2.heating other mediums,such as water,beverager,orange juice and other steam
3.they are extensively applied in chemical industrial,pertroleum and energy source and etc.
