Gas to Liquid Fin Tube Heat Exchangers

Product Details

What is gas to liquid fin tube heat exchangers?

Gas to liquid finned tube heat exchangers are tubular heat exchange devices that enhance heat transfer through fins, primarily used for efficient heat exchange between gas and liquid.

At Datang Fin Tube, we design and manufacture bespoke steam air heaters specifically for industrial applications.

Steam heat exchangers are devices designed to transfer heat efficiently between steam and another fluid, typically a liquid or gas. They play a crucial role in various industrial processes and applications where the exchange of thermal energy is required. The fundamental principle behind steam heat exchangers is to harness the high-temperature steam to heat or cool another fluid without direct mixing, preserving the purity and integrity of both the steam and the target fluid.

Working Principle of Gas-Liquid Finned Tube Heat Exchangers

I. Basic Structure of Gas-Liquid Finned Tube Heat Exchangers

Base Tube: The main part of the heat exchanger, usually made of metal, such as copper, aluminum, or stainless steel. Gas and liquid phases exchange heat within or on their surfaces.

Fingers: Thin sheets attached to the base tube, increasing the surface area of ​​the base tube and thus improving heat exchange efficiency. Fins can be individual metal sheets or integrally formed with the base tube.

II. Working Principle of Gas-Liquid Finned Tube Heat Exchangers

Heat Transfer Path:

The hot fluid (gas or liquid) flows through the outside or inside of the base tube, transferring its heat to the base tube wall.

The base tube wall then transfers heat to the cold fluid flowing through its interior or exterior.

The presence of fins greatly increases the heat exchange area, allowing more heat to be transferred in the same amount of time.

Convective Heat Transfer:

When a fluid flows through the base tube and fins, convective heat transfer occurs due to fluid flow and temperature differences.

Convective heat transfer is the exchange of heat between a fluid and a solid surface caused by temperature differences.

Heat Conduction:

Within the base tube wall and fins, heat is transferred from high-temperature regions to low-temperature regions via heat conduction.

The efficiency of heat conduction depends on the thermal conductivity of the material and the temperature gradient.

Enhanced Turbulence:

The design of the fins often induces turbulence in the fluid, thereby increasing heat exchange efficiency.

Turbulence disrupts the fluid boundary layer, making it easier for heat to transfer from the fluid to the base tube wall or vice versa.

Gas-liquid finned-tube heat exchangers achieve highly efficient gas-liquid heat exchange through the combination of base tubes and fins, utilizing the principles of heat conduction and convection. Their structural design allows the fluid to form turbulence as it flows through the heat exchanger, further improving heat exchange efficiency.
