The invention relates to the technical field of JP cabinets, in particular to an intelligent JP cabinet with dehumidification and heat dissipation functions. The intelligent JP cabinet comprises a cabinet body, wherein dehumidification and heat dissipation devices are installed on left and right side surfaces of the cabinet body, a heat absorption mechanism is installed inside each dehumidification and heat dissipation device, and heat dissipation grooves are formed in positions, corresponding to the heat absorption mechanisms, inside the cabinet body. By means of induced draft fans inside the heat absorption mechanisms, heat inside the cabinet body can be fully absorbed, moisture inside air flows can be effectively removed by means of heating resistance wires inside first dehumidification mechanisms, hot air flows can be subjected to heat exchange effectively by means of evaporators and condensers inside second dehumidification mechanisms, so that the moisture inside the cabinet body is condensed and the effect of reducing air flow temperature is achieved, the air flows after cooling are charged into the interior of the cabinet body, so as to achieve better heat dissipation effect, and the arrangement of deflector vanes inside air exhausting grooves can realize the omnidirectional absorption of hot air flows in the cabinet body and omnidirectional release of cold air flows in the cabinet body, thereby achieving better dehumidification and heat dissipation effects.
