The invention relates to a double-cone-shaped pressurization independent heat dissipation air channel and an individual portable radar overall structure, the double-cone-shaped pressurization independent heat dissipation air channel is composed of a box body and an air channel cold plate and is communicated with the outside, all subsystems are sealed in a transceiver case and do not make direct contact with the air channel, and a conduction and forced convection air cooling mode is utilized; the radiating fins at the high-power device are designed to be gradually reduced in height to form a symmetrical conical channel, the air pressure at the air inlet is increased, the cooling flow is reasonably distributed, the fan is utilized at the air outlet to discharge heat, and the radiating and sealing problems of the high-power device in the transceiving box body are solved. Due to the fact that the heat dissipation air channel has low thermal inertia, the change of the environment temperature can be transmitted to
