YTHRV-04 Vertical heat exchanger

principle

Thermal conduction principle: Thermal conduction is the process of transferring heat from a high-temperature area to a low-temperature area through solid materials or media. In a vertical heat exchanger, the heat source and cold source flow through different pipes and are separated by the tube plate spacing on the shell side wall, allowing thermal energy to be conducted to the cold source inside the heat exchange tubes.

Fluid flow principle: In a vertical heat exchanger, the heat source and cold source flow through the heat exchanger through pipelines to achieve heat transfer. The heat source and cold source achieve convective heat transfer in the heat exchange tube, and through the flow of fluid, heat is transferred from the heat source to the cold source, achieving the transfer of thermal energy.

Thermal convection principle: Convective heat transfer is achieved through the flow of fluids, where molecules carry energy and transfer heat from a heat source to a cold source during the flow process. Vertical heat exchangers improve the effectiveness of heat convection and enhance heat transfer by optimizing fluid flow.

Temperature difference driving principle: Temperature difference is the basic condition for achieving heat transfer. The larger the temperature difference between the heat source and the cold source, the faster the heat conduction. Vertical heat exchangers improve the efficiency of heat conduction and achieve more efficient heat exchange by increasing the temperature difference between the heat source and the cold source.

System composition

The YTHRV-04 vertical heat exchanger system consists of a shell, tube bundle, tube side plate, supporting components, and accessories. The following will provide a detailed introduction to the function and structure of each component.

Shell: The shell is the main part of a vertical heat exchanger, responsible for fixing and supporting other components, and providing pipeline connection ports. The shell is usually made of welded steel plates, which have sufficient strength and stiffness to withstand the internal working pressure.

Bundle: Bundle is the core part of a vertical heat exchanger, consisting of a large number of heat exchange tubes. The material for the tube bundle is usually chosen to be high temperature resistant and corrosion-resistant, such as stainless steel, nickel alloy, etc. The tube bundle is connected to the shell through welding or expansion to ensure the sealing and strength of the heat exchange tubes.

Tube side plate: The tube side plate is a partition on the side wall of the shell side, which divides the shell into two different fluid channels, upper and lower, respectively used for the flow of heat and cold sources. The side plate of the tube is made of metal sheet and welded to the shell, with certain holes for connecting heat exchange tubes.

Supporting components: Supporting components are used to support the tube bundle and shell, ensuring the structural stability and operational safety of the heat exchanger. The supporting components are usually made of steel and connected to the shell by welding or bolts.

Attachment: The attachment includes inlet and outlet pipelines, valves, pressure relief devices, manholes, drain valves, etc., used for the installation, maintenance, and discharge work of the heat exchanger. Attachments are usually selected and installed according to specific needs to meet the requirements of different working conditions.
