When spraying or fertilizers, a grill was formed to face downward so that no pesticides or fertilizers from the liquid flowing down from above were introduced into the interior. In addition, both sides of the grille of the heat sink cover are configured to filter the dust flowing into the inside to protect the heat sink, a fan motor for radiating air and a fan motor for radiating air.

In addition, the controller consists of a controller that controls the power supplied to the thermoelectric semiconductor, the fan motor for air suction, the fan motor for radiating air, and the fan motor for radiating air, according to the working environment of the operator.
