Heat Exchanger Material Thermal Conductivities

Overview

Engineering reference data for Heat Exchanger Material Thermal Conductivities in thermodynamics.

Key Formulas

First Law

$\Delta U = Q - W$

Energy is conserved — heat added minus work done.

Ideal Gas Law

$PV = nRT$

Relates pressure, volume, and temperature of an ideal gas.

Heat Transfer

$Q = mc\Delta T$

Sensible heat transfer.

Carnot Efficiency

$\eta = 1 - T_C/T_H$

Maximum efficiency between two temperatures.

Material Properties

The thermal conductivity of materials is a critical factor in heat Exchanger design, as it directly influences the rate of heat transfer through the tube walls. Materials with higher thermal conductivity generally allow for more efficient heat exchange. The following table summarizes the thermal conductivities for commonly used materials, as extracted from the source data.
