Hoffman Enclosure Temperature Calculator

Formula

The formula to calculate the Enclosure Temperature is:

\[ T_e = T_o + \frac{P}{A \cdot h} \]

Where:

\( T_e \) is the Enclosure Temperature (°C).
\( T_o \) is the Outside Temperature (°C).
\( P \) is the Power Dissipated (W).
\( A \) is the Surface Area (m²).
\( h \) is the Heat Transfer Coefficient (W/m²°C).

Example

Let's say the outside temperature (T_o) is 25°C, the power dissipated (P) is 100 watts, the surface area (A) is 2 square meters, and the heat transfer coefficient (h) is 5 W/m²°C. The enclosure temperature (T_e) would be calculated as follows:

\[ T_e = 25 + \frac{100}{2 \cdot 5} = 35 \text{ °C} \]

So, the enclosure temperature is 35°C.

What is a Hoffman Enclosure?

A Hoffman enclosure is a type of protective casing used to house electrical or electronic equipment. These enclosures are designed to protect the equipment from environmental factors such as dust, water, and temperature fluctuations. Hoffman enclosures are commonly used in industrial and commercial applications to ensure the safety and longevity of sensitive equipment. They are made from various materials, including metal and plastic, and come in different sizes and configurations to suit specific needs.
