Abstract:
PROBLEM TO BE SOLVED: To obtain an outdoor cabinet type communication unit which can be cooled effectively on the inside.
SOLUTION: An enclosed electronic apparatus containing section contains first and second fan boards 63, 64 which are driven to form an inner toner forced circulation air flow 90 in the electronic apparatus containing section 51. A heat exchanger 80 and an outer air exhaust fan 81 are disposed at the upper part of the electronic apparatus containing section. At the part of the heat exchanger 80, the inner forced circulation air flow 90 flows in the X1 direction and the outer air flows in the X2 direction. The inner forced circulation air flow 90 is deprived of heat at the part of the heat exchanger 80 and circulated while being cooled thus air cooling an electronic apparatus.
