Heat exchanger - Wikipedia
A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. [1] . The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. [2] .
换热器的分类和原理动图（上） - 知乎专栏
2022年5月24日 · 换热器（heat exchanger）是一种用于在两种或多种流体之间传递热量的系统。 换热器的分类方式很多种，有按用途分的，加热器、冷凝器等；有按热量传递方式分的，还有按换热材料分的等等，这里，老沙弥就沿袭我们之前一贯的分类法则，从结构和原理进行分类，有助于理解。 这里老沙弥整理的换热，并不包括接触式的换热器，比如凉水塔这些，有需要的，可以移步到老沙弥这一块的文章内容。 二、管壳式换. 最近在跟进一个新闻上的热门项目，用CO2制取 …
Understanding Heat Exchangers - Thomasnet
2019年11月13日 · To understand heat exchanger thermodynamics, a good starting point is to learn about the three modes in which heat can be transferred: conduction, convection, and radiation. The sections below review each of these heat transfer modes. Conduction is the transfer of thermal energy between materials in contact with one another.

2021年12月30日 · Heat exchangers are widely used in space heaters, refrigeration, air conditioning, power stations (nuclear or hydroelectric), and chemical plants. Read Also: Understand The Different Types of Air Conditioners [PDF] How do Heat Exchangers work?
Heat Exchanger - Types, Diagram, Working, Applications , …
A heat exchanger is a device, which transfers thermal energy between two fluids at different temperatures. In most of the thermal engineering applications, both of the fluids are in motion and the main mode of heat transfer is convection.
How do heat exchangers work? - Explain that Stuff
2023年2月18日 · All heat exchangers do the same job—passing heat from one fluid to another—but they work in many different ways. The two most common kinds of heat exchanger are the shell-and-tube and plate/fin. In shell and tube heat exchangers, one fluid flows through a set of metal tubes while the second fluid passes through a sealed shell that surrounds ...
Heat Exchanger: Classification, Types, Pros, Cons - BYJU'S
Heat exchangers are designed to optimize the efficiency of heat transfer by maximizing the surface area available for exchange and promoting effective fluid flow. They consist of two fluid circuits: the hot fluid circuit and the cold fluid circuit.
Heat Exchanger - an overview | ScienceDirect Topics
A heat exchanger is a device that transfers heat between two fluids without them directly coming into contact or mixing with each other. It can be used to cool or heat air, liquids, or gases without contaminating them. You might find these chapters and articles relevant to this topic. Bahman Zohuri, in Physics of Cryogenics, 2018.
