The invention relates to a computer device capable of performing CFD numerical simulation. The invention effectively solves the problem that existing conventional computer device does not have shock absorbing and cushioning functions and the heat dissipating ability is poor. The technical solution is as follows: a main box is arrange in that computer shell, a shock absorbing and buffering device is connected between the main machine box and the computer housing, the computer may be subjected to a load from a vertical, the longitudinal vibration absorbs energy, better protect the computer equipment, a computer case is further provided with a multi-stage heat dissipation mechanism including a circular heat dissipation device and a water cooling device, according to the different temperaturesin the main computer box, the corresponding devices are controlled by the motor controller connected with the temperature sensor, and the heat generated in the computer can be quickly discharged outof the computer through the cooperation of the multi-stage heat dissipation mechanism. Therefore, the stable and reliable working of the computer device is ensured.
