Abstract
The invention is applicable to the technical field of two-way automatic dust removing heat exchange. The invention discloses a two-way automatic dust-removing heat exchange system. A turnover mechanism which is matched with an outer circulating fan and turns over the outer circulating fan is arranged on a frame of the system; two ends of the turnover mechanism are rotatablely connected with the frame respectively; and when the heat exchange system is used for removing dust, the turnover mechanism rotates to ensure that the wind in an outer circulating air channel flows in a reverse direction. The turnover mechanism can make the outer circulating air channel realize two types of outer circulating airflow directions including air drafting and air discharging without changing the rotating direction of the fan, so the two-way dust removal of an air inlet and an air outlet of the outer circulating air channel is realized, the deposition of impurities of dust and the like in an outer circulating passage of a heat exchange machine core is reduced, the low radiating efficiency, which is caused by blockage in the outer circulating air channel when a linkage mode of the heat exchange system and an air conditioner is adopted, is avoided, and the long-term usage heat exchange efficiency of the heat exchange system is improved.
