Oval Tube Finned Tubes

Oval Tube Finned Tubes

Elliptical tube finned tube is a kind of high-efficiency heat exchange element.

Structural Features

Elliptical tube finned tube consists of elliptical tube and fins. The shape of the elliptical tube gives it a larger heat transfer area and better hydrodynamic properties than the round tube for the same flow area. The fins are usually welded on the elliptical tube, which further increases the heat exchange area and improves the heat exchange efficiency.

Working Principle

When the hot fluid and cold fluid respectively in the elliptical tube finned tube inside, outside the flow, through the wall and fins for heat transfer. Due to the increase of heat transfer area and the special flow state of fluid in the elliptical tube, the heat can be transferred from hot fluid to cold fluid more effectively.

Application Areas

HVAC field: used in air heaters, coolers and other equipment to achieve indoor air heating or cooling.

Industrial field: widely used in heat exchangers in chemical, petroleum, electric power and other industries for heating or cooling various process fluids.

Refrigeration field: as the core component of condenser and evaporator to improve the efficiency of refrigeration system.

Advantages

High-efficiency heat exchanger: larger heat exchange area and optimised fluid flow state make it have high heat exchange efficiency.

Compact structure: under the same heat exchange task, it occupies less space and is easy to install and arrange.

Corrosion resistance: it can be manufactured with corrosion-resistant materials and is suitable for a variety of harsh working environments.

Low resistance: the fluid flow resistance in the elliptical tube is relatively small, reducing the pump power consumption.

Selection Notes

Heat transfer requirements: according to the specific heat transfer task, determine the required heat transfer area and heat load.

Fluid properties: consider the type of fluid, flow, temperature, pressure and other factors, select the appropriate material and structure.

Working environment: Consider the temperature, humidity, corrosiveness and other factors of the working environment, and select corrosion-resistant and high-temperature-resistant materials.

Installation: According to the actual installation conditions, select the appropriate connection and installation size.
