There are a lot of electric power or communication equipment inside the cabinet. These equipment will dissipate a lot of heat in a long working time, which makes the temperature rise continuously. The cabinet is generally used outdoors, directly under the influence of climate, directly exposed to the sun, it will produce high temperature, and it will also produce heat when working. If it does not dissipate heat in time, it will seriously affect the normal work of the equipment So it's very important to install cooling fan in the cabinet. Let's introduce the selection of cooling fan in the cabinet!

Firstly, according to the size of the cabinet and the heat dissipation of the components in the cabinet, the power and size of the fan should be selected according to the required exhaust volume. The fan in the cabinet mainly considers the normal temperature inside the cabinet and the maximum temperature outside the cabinet, obtains a temperature difference and the air exchange rate of the fan, estimates the air capacity in the cabinet, and then obtains the time for an air replacement, so as to reduce the cost To select the fan that is actually needed, we need to consider the moisture-proof, water-proof and dust-proof functions of the electric cabinet, because we will use it in the outdoor environment where there is a lot of moisture and dust. At the same time, according to the size of the cabinet, we can choose the appropriate equipment with different power.
