Description

Technical Field

[0001] The utility model relates to the technical field of closed cooling towers, in particular to a closed cooling tower for environmentally friendly closed-circuit circulation cooling. Background Art

[0002] A cooling tower is a commonly used cooling device. Its working principle is that the high-temperature circulating water to be cooled transfers its own heat to the air through latent heat and sensible heat exchange with the air inside the cooling tower to achieve cooling. The existing technology has the following problems:

[0003] A fan is usually installed on the top of a closed cooling tower used for environmentally friendly closed-loop cooling. However, when the closed cooling tower is not in use, dust in the air may fall into the cooling tower through the fan, which may affect the cooling tower when it is started to be used. The fan is usually installed on the top of the cooling tower. When there is a problem with the fan, the staff needs to climb to the top of the cooling tower with the help of a ladder to repair the fan. However, the ladder usually installed on the outer wall of the cooling tower is not very stable. The staff may shake during the climbing process, which may cause the staff to slip. In addition, the ladder cannot be stored, and non-staff may climb up the cooling tower to damage the fan. Utility Model Content
