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] .

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 ...
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.
12 Different Types of Heat Exchangers & Their Application [PDF]
2021年12月30日 · Heat exchangers are types of equipment used to transfer heat from a hot liquid to a cold liquid. They are considered useful for performing the function of changing the temperature of the more valuable liquids used in the process.
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 Exchangers – Visual Encyclopedia of Chemical Engineering …
Heat exchangers take the energy from a hot stream and use it to heat a cooler stream. Most of the heat exchangers used in industry are shell and tube, air-cooled, or plate and frame. The table of contents below links to different types of heat exchangers.
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.
Heat exchanger | Energy Efficiency & Heat Transfer | Britannica
2024年12月28日 · Heat exchanger, any of several devices that transfer heat from a hot to a cold fluid. In many engineering applications it is desirable to increase the temperature of one fluid while cooling another. This double action is economically accomplished by a heat exchanger.
A basic introduction to heat exchangers - GlobalSpec
2023年9月20日 · Heat exchangers are central in modern industry, serving as essential components in chemical processing, energy production, automotive systems and HVAC applications. These devices enable controlled heat transfer between different fluids at different temperatures while keeping them from mixing with each other.
