Water Cooled Heat Exchanger Calculation

The formulas on this page allow one to calculate the temperature rise for a given water cooling application where the power dissipation and.

Water cooled heat exchanger calculation.

The specific heat of the oil is 2 2 kj kg k. They will also calculate the number of tubes needed for a shell and tube heat exchanger and to calculate the pipe length needed for a double pipe heat exchanger. Btu calculator btu formulas for water circulating heat transfer. Enter the fluid data and enter 5 of the 6 available inputs under flow rates and temperatures.

Calculation of heat exchanger. Cooling of liquid light hydrocarbons. Overall heat transfer coefficient calculate overall heat transfer coefficients for walls or heat exchangers. A btu is a relatively small amount of energy.

Water cooling is often used in order to help dissipate or at least transfer large amounts of dissipated power heat which can be typical of many power electronics and repetitive pulsed power applications. Enter the btu requirement temp in temp out and gpm are shaded for hot and cold enter two of the three shaded portions for hot enter two of the three shaded portions for cold. To approximate the results of a heat transfer system. Assume the cpu inserts a constant rate of energy q into the cooling system.

The currently calculating value will always be highlighted in green. These templates use s i. About equivalent to the heat generated by striking 1 stick match. In other words the rate of heat transfer is directly proportional to mass flow rate.

A btu is an abbreviation for b ritish t hermal u nit which is the amount of energy required to raise 1 pound of water 1 degree fahrenheit at sea level. This video describes how much steam is required to raise temperature of water to a certain degree in a heat exchanger. The rate of flow of oil is 1 kg s. Consider a parallel flow heat exchanger which is used to cool oil from 70 c to 40 c using water available at 30 c the outlet temperature of the water is 36 c.

Cooling of air or flue gas. A box will be highlighted yellow if it needs input. When btu requirement is known most applications. The basic heat exchanger design equation can be used for a variety of types of heat exchangers like double pipe heat exchangers or shell and tube heat exchangers.

Download the excel spreadsheet templates in this article to make preliminary heat exchanger design calculations. Heat transfer theory tells us that the log mean temperature difference is the average temperature difference to use in heat exchanger design equation calculations. This calculator will help determine which exchanger has enough heat transfer capacity for your system.
