Abstract

PURPOSE:To simplify the maintenance of a cooling fan by a method wherein a fan package which can be mounted or dismounted to or from a shelf in accordance with the same specification as th package of the electronic circuit is prepared, and the electronic circuit is cooled. CONSTITUTION:The fan package 62 consists of a motor 52, the fan 51 and a rectifying cover 71, sucks F a cooling air by means of the fan 51, sends an air to a circuit element mounted to the package 22, which generates a large amount of heat, and cools the element, and discharges G a hot air. The circuit package, which generates a small amount of heat, is cooled at low cost through a natural convection H. According to this constitution, a forced cooling system can be introduced at low cost to places where heat generation is often dispersed while maintenance is also easy.
