Among the many methods, ventilation of the room is a preferred method: the problem of indoor air pollution is solved, and the problem that indoor air is not fresh is solved, so that the fresh air fan gradually enters the life of people.
When the fresh air machine is used for air conditioning and cooling in summer and heating in winter, the fresh air machine is used for ventilating the room, so that the quality of the indoor air is guaranteed to be improved, the influence on the indoor temperature and humidity is reduced to the greatest extent, the energy consumption in the processes of air conditioning and cooling in summer and heating in winter is reduced, and the purposes of energy conservation and emission reduction are achieved. In order to solve the problem, people improve and research the core body of the heat exchanger of the fresh air fan.
The energy-saving mode of the fresh air machine in the current market is as follows: outdoor new trend and indoor exhaust are the mode of quadrature cross flow respectively and pass through new fan heat exchanger core, because there is temperature and humidity difference in the air current of conducting strip both sides, and two strands of cold and hot air flows take place heat conduction and lead wet phenomenon through the conducting strip, accomplish sensible heat and total heat exchange process.
As the existing fresh air machine in the market, the flow modes of outdoor fresh air and indoor exhaust air in the core body of the heat exchanger of the fresh air machine are orthogonal cross flow instead of counter flow, the sensible heat and total heat exchange efficiency of the core body of the heat exchanger of the fresh air machine is low.
In order to improve the heat exchange efficiency of the core body of the heat exchanger of the fresh air fan, the logarithmic mean temperature difference (mean value of integral of temperature difference of cold and hot fluid in the heat exchanger in the heat transfer process) is required to be improved. Because the logarithmic mean temperature difference is the largest in the counter-flow process, the exchange efficiency of sensible heat and total heat of outdoor fresh air and indoor exhaust air in the core body of the heat exchanger of the fresh air fan can be improved by adopting a counter-flow mode.

The invention has the following beneficial effects:
the logarithmic mean temperature difference is improved through the countercurrent flowing direction of the outdoor fresh air and the indoor exhaust air in the core body of the heat exchanger of the fresh air fan.
The fresh air and the indoor exhaust air flow in a method of mutually alternating interlayers in a core body of a fresh air fan heat exchanger, temperature and humidity difference exists between the fresh air and the indoor exhaust air, and temperature and humidity conduction is carried out on two sides of the heat conducting fin to finish sensible heat and total heat exchange processes.
The sensible heat exchange core body or the total heat exchange core body can be assembled by selecting different heat conduction materials of the metal foil or the moisture conduction film, and the temperature and the humidity of indoor fresh air can be adjusted by selecting a parallel or serial connection method according to the indoor temperature and humidity requirements.
