Double Tube Heat Exchanger

Introduction

A double-tube heat exchanger is a shell-and-tube heat exchange device consisting of two concentric tubes. One medium flows through the inner tube, and another medium flows through the annular space between the inner and outer tubes. Heat exchange is achieved through the tube walls. Its unique feature is the double-layered tube structure, where the inner and outer tubes form independent flow channels, making it particularly suitable for operating conditions with strict requirements for leak prevention and cross-contamination prevention.

Quick details

Type: used for evaporation, heating, condensation, and cooling processes

Place of Origin: Jiangsu, China

Product Components

1. Inner Tube: Carries one type of fluid; typically made of stainless steel, copper alloy, titanium, Hastelloy, or special steel, depending on the characteristics of the medium.

2. Outer Tube: Encloses the inner tube, forming an annular flow channel, carrying another type of fluid.

3. Bend/Pipe Box: Connects multiple tubes, forming a long flow channel, allowing the fluid to travel back and forth multiple times, increasing the heat exchange distance.

4. Support and Shell: Supports the entire tube assembly and provides insulation.

Features

1. High-efficiency heat transfer: The concentric tube design allows for efficient heat exchange between the two fluids, resulting in high heat transfer efficiency.

2. Prevention of cross-contamination: The double tube sheet structure or double tube design effectively prevents mixing between the fluid inside the tubes and the shell-side fluid, ensuring fluid purity and making it suitable for applications requiring extremely high purity.

3. Compact structure: The double tube heat exchanger has a compact structure, occupies little space, and is easy to install and arrange.

4. Easy maintenance: Generally, the double tube heat exchanger has a relatively simple structure, low maintenance costs, and the inner tubes of some models can be removed for easy cleaning and maintenance.

5. Strong adaptability: It can handle a variety of fluids, including gases, liquids, and mixtures, and can be applied to different industrial fields and operating conditions.

Application Areas

1. Chemical Industry: Used in processes such as cooling, heating, or temperature control.

2. Food Processing: Used for heat exchange in the production of dairy products, beverages, etc.

3. HVAC: Used for heat recovery and utilization in systems such as heat pumps and boilers.

4. Pharmaceutical Industry: Ensures temperature control during the production and storage of pharmaceuticals.
