Abstract

The invention provides a heat exchange base material, a runner heat exchanger rotary core carrier, a runner heat exchanger rotary core, a preparation method thereof and a runner heat exchanger. The heat exchange base material is prepared by following steps: mixing a composite graphene wrapped metal material with a composite modifier, and carrying out wet film forming to obtain a porous heat-conducting film material. The runner heat exchanger rotary core carrier comprises the heat exchange base material. The runner heat exchanger rotary core comprises the runner heat exchanger rotary core carrier and a coating layer, and the coating layer comprises following raw materials: a moisture absorption drying agent, an organic dispersing agent and a solvent. The preparation method of the runner heat exchanger rotary core comprises the following steps: mixing a moisture absorption drying agent, an organic dispersing agent and a solvent to obtain a coating agent, loading the coating agent onto the runner heat exchanger rotary core carrier, and performing aerobic calcination. The runner heat exchanger comprises the runner heat exchanger rotary core. The runner heat exchanger rotating core carrier, the runner heat exchanger rotating core and the runner heat exchanger, which are prepared from the provided heat exchange base material, are high in heat exchange efficiency and long in service life, and have a self-cleaning function.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a heat exchange substrate, a rotary heat exchanger core carrier, a rotary heat exchanger core, a preparation method thereof, and a rotary heat exchanger. Background technique [0002] In recent years, with the increasing shortage of energy, energy conservation has become a major focus of attention in the energy industry. According to statistics, building energy consumption accounts for more than 30% of the total energy consumption of the society, and is still growing at a rate of 1% per year. The energy consumption of buildings in the United States accounts for more than 40% of the total energy consumption. Building energy consumption includes heating, air conditioning, lighting, hot water, household appliances and other kinetic energy consumption. Of this, heating, air conditioning and ventilation accounted for 65%. With the continuous growth of energy demand, the development o...
