Dehumidification device with enhanced dehumidification effect

A dehumidification device with enhanced dehumidification effect comprising:

• a gas cooler receiving a first air gas from outside and condensing said first air gas into a first condensing gas and a first condensing liquid, wherein said gas cooler defines a first airflow path for said first air gas in a first direction, and said first air gas is condensed within said first airflow path;
• a heat exchanger arranged at one side of said gas cooler, wherein said heat exchanger has at least one inlet and at least one outlet, said first condensing gas flows from said gas cooler across a periphery of said heat exchanger to cool said heat exchanger, said at least one inlet receives a second air gas from outside, said heat exchanger defines a second airflow path for said second air gas in a second direction different from said first direction, said second airflow path crosses said first airflow path, said second air gas is condensed into a second condensing gas and a second condensing liquid by passage through said cooled heat exchanger for supplemental condensing of outside air, said second air gas is condensed within said second airflow path, and said second condensing gas and said second condensing liquid are expelled from said at least one outlet;
• and
• a gas heater arranged at one side of said heat exchanger, and said heat exchanger is thereby arranged between said gas cooler and said gas heater, wherein said gas heater receives and heats said first condensing gas flowing past said periphery of said heat exchanger and said second condensing gas expelled from said at least one outlet of said heat exchanger, said gas heater thereby generates dry air, and said gas heater expels said dry air.
