PURPOSE: An exhaust heat supply device using a bottom surface blocking film of a cargo box frame is provided to easily unload goods by melting a part of a bottom surface of the frozen goods with driving for 30 minutes. CONSTITUTION: Ah exhaust heat supply device using a bottom surface blocking film of a cargo box frame comprises a fluid path forming unit and an exhaust heat transferring unit (200). The fluid path forming unit is formed on a bottom surface of a truck cargo box and comprises a plurality of L-shaped bottom surface reinforcing walls and a blocking film (120). The L-shaped bottom surface reinforcing wall reinforces the cargo box frame in order not to be bent. The blocking film is welded on one side of the L-shaped bottom surface reinforcing wall and seals space wrapped by the L-shaped bottom surface reinforcing wall and the bottom surface of the truck cargo box. The exhaust heat transferring unit compulsorily transfers exhaust gas from an exhaust line of a truck body to the fluid path forming unit. The exhaust heat transferring unit comprises a T-shaped connection member (210), a transferring unit (220), and a valve (240). The T-shaped connection member is welded on one side of the exhaust line. The transferring unit transfers the exhaust gas flowing through the bottom surface of the T-shaped connection member to the upper part. The valve opens or closes internal space of the T-shaped connection member by the rotation.
