A heat exchanger is a device used to transfer heat, usually to transfer heat from one fluid to another without them mixing. A heat exchanger usually consists of a number of parallel pipes in which one fluid flows through the pipe and another fluid flows through the outside of the pipe. In this way, heat can be transferred from one fluid to another for heating or cooling purposes. Heat exchangers are widely used in many industries, such as chemical, pharmaceutical, food processing, air conditioning and heating systems, etc.
Heat exchanger usually consists of the following components:
1. Heat exchange pipe: Pipe used to transfer heat, usually made of metal materials, such as copper, stainless steel, etc.
2. Heat exchange surface: A surface used to transfer heat, usually consisting of metal sheets or pipes. The greater the surface area, the higher the heat transfer efficiency.
3. Housing: Housing, usually made of metal or plastic, used to secure heat exchange pipes and surfaces.
4. Seals: Seals used to prevent media leakage, usually made of rubber or silicone rubber.
5. Support: A support used to support a heat exchanger, usually made of steel or cast iron.
6. Import and export pipes: pipes used for medium entry and exit, usually made of metal or plastic.
7. Cleaning hole: A hole used to clean the inside of the heat exchanger, usually located on the upper or side of the heat exchanger.
8. Insulation layer: Insulation layer used to keep the temperature of the heat exchanger stable, usually made of glass wool or polyurethane foam.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them.
