The utility model relates to a by-pass cooling device of a clothes dryer. The utility model is composed of a heat exchanger which is arranged at the outer part of a roller of the clothes dryer, a wind inlet, a wind outlet of the heat exchanger and a by-pass wind admitting passage. The wind inlet of the heat exchanger and the by-pass wind admitting passage are communicated with each other, a wind door plate is installed between the wind inlet of the heat exchanger and the by-pass wind admitting passage, the wind door plate (5) is installed on a rotating shaft or is positioned along a track of the wind outlet and the by-pass wind admitting passage, and the wind door plate (5) does the rotating action or the sliding action between positions which can fully shield the wind outlet of the heat exchanger and the by-pass wind admitting passage. When the utility model is in a cooling process, the energy in the heat exchanger of the clothes dryer can be maintained, the preheating time of the clothes drying of next time is shortened, and the cooling time is saved.
