Energy-saving plate heat exchanger

Abstract

The utility model discloses an energy-saving plate heat exchanger, which relates to the technical field of plate heat exchangers and comprises a heat exchanger component and a filter component, and the filter component is used for filtering cooling media entering heat exchange fins. The filtering assembly comprises a filtering unit, a pollution discharge unit and a cleaning unit; the filtering unit is used for filtering the cooling medium; the pollution discharge unit is used for discharging the filtered impurities; the cleaning unit is used for cleaning the inner wall of the filtering unit by utilizing the impact force of water flow. According to the utility model, the filtering of cold media can be realized by arranging the filtering assembly, the cold media mingled with impurities are effectively prevented from entering the channels among the heat exchange plates, the channels of the heat exchange plates are kept in a good conduction state, and meanwhile, the inverted concave valve plate moves upwards to remove the blockage of the sewage discharge channel, so that the impurities can be discharged outwards, and the heat exchange efficiency is improved. And compared with a traditional dismounting and cleaning mode, the operation is simpler and more efficient.
