Data acquired system and CT apparatus using the same

A computerized tomography apparatus comprising a data acquired system, the data acquired system comprising:

• a main structure with a cavity formed therein, the cavity having a bottom for mounting a circuit board with electrical components thereto;
• a fan assembly disposed on the main structure;
• and
• an airflow guide disposed within the cavity and configured to guide airflow from the fan assembly for heat dissipation of the electrical components, the airflow guide positioned at a distance above the electrical components to form a gap between the airflow guide and the electrical components, wherein a sidewall of the cavity is provided with an air vent corresponding to the gap such that the airflow passes through the gap and is discharged from the air vent.

A method of assembling a data acquired system, the method comprising:

• mounting a circuit board to a bottom of a cavity of a main structure, the circuit board including electrical components;
• coupling a fan assembly to the main structure;
• and
• coupling an airflow guide within the cavity, the airflow guide configured to guide airflow from the fan assembly to dissipate heat generated by the electrical components, the airflow guide positioned at a distance above the electrical components to form a gap between the airflow guide and the electrical components, wherein a sidewall of the cavity is provided with an air vent corresponding to the gap such that the airflow passes through the gap and is discharged from the air vent.
