Fuel cell cooling system in fuel cell bus

摘要

The present invention relates to a fuel cell cooling system for a fuel cell bus for cooling a fuel cell installed in a fuel cell bus, the invention relates to a fuel cell cooling system for cooling a fuel cell installed in a fuel cell bus, comprising: a plurality of radiators disposed at the rear of a loop of a fuel cell bus; A plurality of cooling fans grouped in correspondence with the number of the radiators and disposed on the radiator, the cooling fans being implemented as an overlapping fan type of upper and lower pairs of upper and lower fans; A temperature sensor installed at an inlet and an outlet of each of the radiators for sensing the temperature of the cooling water circulated by each of the radiators; And a control unit for controlling the grouped cooling fans so that the amount of air supplied to each of the radiators is controlled corresponding to the temperature values of the cooling water sensed by the temperature sensors. Thus, the present invention can improve the cooling efficiency, increase the durability of the cooling fan, and reduce the noise.
