(57) [Abstract] [Problem] It is possible to sufficiently exhibit waterproof and dustproof effect without requiring extremely high airtightness, suppress dew condensation in a closed housing, eliminate the need for a heat exchanger, improve maintainability, and maintain. Provided is an electronic device housing capable of exhibiting waterproof and dustproof effects at the time and capable of suppressing restrictions on an external design while taking measures against sunlight. An individually sealed module box for individually sealing electronic components mounted with electronic devices for each function, and a waterproof housing having the individually sealed module box and having a waterproof / dustproof function and having a drain hole. Electronic unit 1 consisting of three And a heat sink 11 for radiating heat of the electronic components to the back of the waterproof housing 3, a duct 20 for forced air cooling of the heat sink 11, and an external waterproof fan. 14 is provided. |
