The computer cooling device and the all-in-one computer are provided with a first fan, a filter box and an activated carbon filter plate. The first fan effectively extracts the hot air generated by the all-in-one computer and sends it into the filter box. This process not only provides the computer with necessary auxiliary heat dissipation functions and ensures its stable operation, but also the activated carbon filter plate built into the filter box will filter and purify the hot air to make it fresh and clean.

[0016] 2. The computer cooling device and the all-in-one computer are provided with a refrigeration box, a semiconductor refrigeration sheet, a cold conduction plate, an air inlet hole and an exhaust hood. When the filtered and purified hot air enters the refrigeration box, the semiconductor refrigeration sheet is combined with the cold conduction plate to cool the hot air passing through the air inlet hole, so that the hot air is converted into cold air, and then the cold air is blown out through the exhaust hood. In an environment with a high indoor temperature, by delivering cold air to a user who is operating a computer, the user's cool feeling can be enhanced, and the discomfort caused by the high temperature can be effectively alleviated, thereby protecting human health and allowing the user to concentrate on work.

[0018] 4. The computer cooling device and the all-in-one computer are provided with a motor, a rotating shaft and a beating rod. The motor can drive the beating rod to rotate, and then the beating rod continuously beats the displacement plate to make the brush vibrate.

[0019] 5. The computer cooling device and the all-in-one computer are provided with an ash discharge port, a collection box, a filter and an exhaust pump. The dust cleaned from the hot end surface of the semiconductor refrigeration plate will fall to the ash discharge port and then be guided and discharged into the collection box.

By providing a motor 605, a rotating shaft 606 and a beating rod 607, the motor 605 can drive the beating rod 607 to rotate, and then the beating rod 607 continuously beats the displacement plate 604 to make the brush 602 vibrate, and the dust adhering to the brush 602 can be shaken off by the shaking, so as to prevent the adhering dust from affecting the subsequent cleaning effect of the brush 602. By providing the ash discharge port 404, the collection box 7, the filter 701 and the vacuum pump 702, the dust cleaned from the hot end surface of the semiconductor cooling plate 401 will fall to the ash discharge port 404 and then be guided to be discharged into the collection box 7.
