Cross flow heat exchange device

The utility model provides a cross flow heat exchange device which is provided with a device box body and a heat exchange mechanism in the device box body, the heat exchange mechanism comprises a shell and a plurality of cold air pipelines penetrating from the top of the shell to the bottom of the shell, and a water outlet is formed in the bottom of the shell. The lower end of the cold air pipeline is communicated with the evaporator, the upper end of the cold air pipeline is communicated with the outside of the device box body, and cold air generated by the evaporator flows to the outside ofthe device box body through the plurality of cold air pipelines; a moisture removal pipeline and an air supply pipeline which are communicated with the interior of the shell are arranged on the devicebox body; the moisture exhaust pipeline is communicated with a moisture exhaust port of the drying room, and high-temperature humid and hot air exhausted from the drying room enters a shell of the heat exchange mechanism from
