A heat exchange system of the invention includes multiple grids, a blower including an external rotor motor and a wind blade, a compressor, and a box having multiple exhaust inlets. The exhaust inlets are disposed on the side of the box, the grid is disposed at an exhaust outlet of the box, the blower is disposed in the box and below the grid, and the compressor is disposed on bottom surface in the box. The blower is an external rotor axial fan, and the wind blade is disposed outside a rotor of the external rotor motor. The heat exchange system of the invention features simple structure, low cost, large air output, and good blowing effect, and is high efficient and power saving.
Un système déchange de chaleur de linvention comprend plusieurs grilles, un ventilateur de soufflage comportant un moteur de rotor externe et une pale, un compresseur et un boîtier pourvu de plusieurs entrées déchappement. Ces dernières sont disposées sur le côté du boîtier, la grille est disposée à une sortie déchappement du boîtier, le ventilateur est disposé dans le boîtier et sous la grille, et le compresseur est disposé sur la surface inférieure du boîtier. Le ventilateur est de type axial à rotor externe et la pale est disposée à lextérieur dun rotor du moteur de rotor externe. Le système déchange de chaleur de linvention offre une structure simple, un faible coût, une grande sortie dair et un bon effet de soufflage. Il est également très efficace et très économe en énergie.
