The present invention relates to agricultural electric fan heater, is installed on the rear end of the main body 100 for discharging the cold air in accordance with the rotation of the blowing fan 220, connected to the blower motor 210 in the forward direction agricultural consisting of blower 200 and the are arranged in front of the blower rich heater 310 for heating to discharge a hot air to the incoming cold air is fitted and fixed to the fixed perforated partition plate 320, the heater and the compartment song 300 An electric fan heater, the heater and the compartment blower cold air which is passed to the inlet of heater border outside concatenated holes 324 of the fixed porous partition plate (320) narrowed in the inner center of the direction of 300, grouped as the discharge blower discharge pressure and the speed is related to agricultural electric Heat characterized in that the cold air guide is configured including a duct (400) with increasing wind pressure guide portion 420 that guides to be increased. Therefore, as through the cold air guide ducts having a cold air flowing by the blower unit wind pressure increase guide diameter formed stepped in external light naehyeop shape narrowed gathered discharged to the inside center of the direction passing through the heater by the guide so that the increase in the blower discharge pressure and speed a hot air mixed with the discharge crops there at the same time even if harmed by the hot air can blow a large area to more distant improve the thermal efficiency of the electric fan heater is an effect that can be a large area of heat with minimal on-site construction algebra there.본 발명은 농업용 전기 온풍기에 관한 것으로서, 본체(100)의 후단부에 설치되어 송풍모터(210)에 연결된 송풍팬(220)의 회전에 따라 냉풍을 전방으로 배출하는 송풍기(200)와, 상기 송풍기의 전방에 배치되어 유입된 냉풍을 가열해 열풍으로 배출시키는 히터(310)가 고정 다공 구획판(320)에 결합 고정된 히터 및 구획 송풍부(300)로 이루어진 농업용 전기 온풍기에 있어서, 상기 히터 및 구획 송풍부(300)의 고정 다공 구획판(320)의 히터 테두리 외곽 연접통공(324)들을 통과해 유입되는 냉풍이 내측 중심부 방향으로 좁아지게 모아져 토출되면서 송풍 토출 압력과 속도가 증가되도록 가이드하
