The technology used in heat exchanger tubes is very old and involves different methods of heat transfer, such as radiation, convection, and heat conduction. A heat exchanger tube is a device used to transfer heat from one medium to another for both cooling and heating processes. It separates the media being used, and the conduction process transfers the heat through these exchanger tubes. The medium can be a liquid, vapor, or gas. The heat exchanger tube expander tools are mainly used when the tube and plate heat exchangers are used. Refrigerators, chemical plants, air conditioners, power plants, etc., use heat exchange processes, sometimes for energy efficiency. The overall look of the plant can be determined by these tubes.
Types of Heat Exchanger Pipes and Their Characteristics:
A particular heat exchanger tube selection depends on the heat transfer rate. The heat load and temperature required also determine the size of the heat exchanger tube. These can be manufactured in U-Bent shapes or to bespoke lengths. It is interesting to note that the basic configuration of heat exchangers remains the same regardless of their different sizes and complexity. Heat exchangers and their applications are classified according to their design characteristics. These characteristics determine the performance of the pipe, among other factors. These characteristics are very important for the heat exchangers to maintain the controlled heat throughout the process.
Classification According To Flow Configuration:
The fluid flow movement is also considered in the heat exchanger tubes. There are four main flow patterns: 1. Parallel flow in which the fluid moves in the same direction. 2. Counterflow, in which the fluid moves in the opposite direction, which is more efficient than parallel flow heat exchangers. 3. Cross flow allows the fluid to move perpendicular to each other. 4. Hybrid flow, where the flow can go through many times. The flow rate of the liquid in the exchange pipe is very important. This is called the flow rate. The heat exchanger’s tube expander machine price will be affordable in the market for providing the best sale. However, this also increases mass and velocity, and reducing the pressure ultimately makes energy removal a challenge.
Classification According To the Mechanism of Heat Transfer:
Heat exchanger tubes have two heat transfer mechanisms – single-phase or two-phase. There is no phase change in the first type of heat transfer process. Simply put, the fluid remains in the same state as it entered the heat exchanger tube. It helps the liquid change state during the heat transfer process. According to the mechanism of heat transfer, Heat exchangers can, therefore, be classified into four types:
- Single-phase convection on both sides
- Single phase on one side and two phases on the other.
- Two-phase meeting on both sides
- Combined radiative and convection heat transfer.
According To The Construction Method, Heat Exchanger Pipes Can Be Classified As Follows:
Capacitive heat exchanger – Here, warm and cold liquid flows alternately through the same channel. There are two types – static and dynamic heat exchangers.
Recuperation heat exchanger – Here, each liquid flows simultaneously through its channel. There are two types – direct and indirect contact heat exchangers.
The components and materials used – depending on the type of heat exchanger and the application. Commonly found ones include tubes, shells, sheets, fins, threaded pipes, etc.
