Heat-dissipating structure with air-guiding device

A heat-dissipating structure, comprising:

• a water-cooling device having a main body with a contact face in contact with a surface of a central processing unit and an opposing connection face;
• a fan for providing airflow to dissipate heat from the water-cooling device;
• a support device assembled between the main body of the water-cooling device and the fan to form an accommodating space therebetween, the support device having a bottom seat affixed to the connection face of the water-cooling device and four fixed posts enclosing the accommodating space, each of the fixed posts having an upper side connecting with one corner of the fan and a lower side fixed to the bottom seat;
• and
• an air-guiding device disposed in the accommodating space and secured to the bottom seat, the air-guiding device having an air-guiding face on a surface thereof, the air-guiding face being an oblique face extending outwardly from an upper end thereof adjacent the fan to an opposing end adjacent the bottom seat;
• wherein the fan provides air flow through the accommodating space and over the air-guiding face of the air-guiding device for guiding air flow from the fan to change direction and dissipate heat from the water-cooling device.
