A (mm) is the unit measurement for thermal conductivity. Other values include a (W), m (Kelvin), R (Rens), T (pieces/cm), and C (piece/cm). A (mm) is the common standard unit measurement for thermal conductivity. The other specifications are usually specified for specific purposes, but the general rule is that the higher the value of the thermal conductivity, the lower the cost of cooling. The highest value is given for metals, while low values are given to alloys and nonmetals.
Why use a brazed plate heat exchanger rather than direct air or water heat transfer? The primary reason is that direct heat transfer can create bubbles in the materials that can cause friction in moving air. In a brazed heat exchanger, the heat transfer coefficient is always much better than air or water. The second reason is the ability of the system to rapidly attain high temperature. And the third reason is the smooth operation and maintenance of the system.
How are the water and gas cooled in the brazed plate heat exchanger system? The gas is cooled with the help of water. Cool air flows into the transfer plates, which carry heat from the gas and radiate it out. The water is used to transport the cool air into the rest of the system. There are one ventilator that are open at all times and one fixed-beam that control the cooling.
