Copper Alloy Steel Heat Exchanger Bundle C12200 C70600 for Maximum Heat Transfer

Tube bundle heat exchanger is a typical heat exchange equipment that makes two fluids with different temperatures exchange heat. Through this device, one fluid can be cooled and another fluid can be heated to meet their respective needs. The equipment is widely used in chemical, petroleum, pharmaceutical, energy and other industrial sectors, and is one of the indispensable important equipment in chemical production.

Tube bundle
In the shell and tube heat exchanger is the simplest single tube heat exchanger, if you need to increase the heat transfer surface, generally use the method of increasing the number of tubes, the tube bundle can be divided to prevent the tube flow rate and heat transfer coefficient after the increase in the number of tubes, from the perspective of manufacturing, installation, operation, generally use even tube and the number of tubes should not be too much.

The fluid channel composed in the heat exchange tube of the tube bundle heat exchanger is called the tube path, and the fluid channel composed outside the heat exchange tube is called the shell path. The working medium enters a heat transfer tube through an inlet nozzle at the end of the head, and the flow can realize a one-pipe, two-pipe and four-pipe structure according to the technological requirements; The other type of working medium enters the shell through an inlet nozzle at one end of the shell and is evenly distributed outside the heat transfer tube, and its flow state can be provided with different types and numbers of baffles in the bundle according to the process requirements. Two different temperature of the working medium into the heat exchanger, the relatively high temperature of the working medium through the heat exchange tube wall to transfer heat to the relatively low temperature of the working medium, the relatively high temperature of the working medium is cooled, the relatively low temperature of the working medium is heated, and then to complete the goal of the two fluid heat exchange process

Heat exchanger tube bundle is the core component of tubular heat exchanger, its main functions are as follows:

1.Support pipe: The tube bundle provides a stable structural foundation to ensure the stability of the overall structure of the heat exchanger. The position and Angle of the tube bundle have an important effect on the heat transfer efficiency, so it needs to be accurately calculated and analyzed during the design and installation. 
2.Separation medium: When the hot medium contains impurities, the tube bundle helps to separate different types of media to ensure the accuracy of heat transfer. This can be done by changing the structure of the tube bundle, such as setting up specific partitions or bending sections of the tube.

3.Heat transfer: The tube bundle is a channel for the hot medium to transfer heat to another medium to achieve cold and heat exchange. The material, inner diameter and arrangement of the tube bundle will affect the heat transfer efficiency. Metal pipes such as copper, steel, stainless steel, etc. are often used to make tube bundles so that they can withstand high temperature and high pressure environments. 

4.Cleaning and maintenance: Because the tube bundle is the core part of the heat exchanger, over time, it is easy to accumulate dirt and scale, affecting the heat transfer efficiency. Therefore, the tube bundle design should take into account the convenience of cleaning, and sometimes include easy to replace parts, so as to facilitate regular maintenance.

5.Improve energy efficiency: Through heat exchange, the tube bundle can convert waste heat into usable heat energy, improve energy efficiency and reduce energy consumption. 

6.Maintaining temperature balance: In industrial production, heat exchangers help transfer heat between different media and maintain temperature balance, which is essential to ensure production efficiency and quality.

7.Improve equipment efficiency: In some equipment, such as steam turbines, tube bundles help cool and reduce pressure to improve the efficiency of the equipment and extend its service life.

8.Seal: The tubular heat exchanger design includes two types of seal: the seal between the tube bundle and the tube plate and the seal between the tube bundle and the shell. These seals need to have good temperature resistance, corrosion resistance and pressure resistance to ensure the long-term stable operation of the heat exchanger.
