In order to solve the problem of temperature control of communication base station, outdoor equipment box or workshop equipment, the team uses the characteristics of absorbing latent heat when the phase change material occurs, fills in a certain amount of phase change materials in the outdoor case, equipment box and signal box, and uses the air inlet / exhaust fan and the corresponding internal temperature monitoring device to achieve the effect of temperature control.

When the temperature of the environment outside the box is lower than the phase change temperature and the temperature inside the box is higher than the specified temperature of the equipment, the device of the ventilation control system will input the air outside the box to the box for the box refrigeration, on the other hand, the energy will be stored in the phase change material.


When the ambient temperature outside the box is higher than the phase change temperature or the temperature inside the box is lower than a specified temperature, the ventilation control system will stop working and release the stored cold energy to achieve the purpose of refrigeration.


In this process, only a little electricity is consumed (fan power consumption), but it can well solve the problem of temperature control of equipment or outdoor chassis.
