PURPOSE: To facilitate the replacement and demounting of the equipment supported by a cradle by installing a heat exchange surface which contacts the equipment and performs the transfer of heat and a radiator which is connected with each heat exchange surface and carries out heat exchange, in the cradle for equipment which supports the equipment which necessitates heat exchange in an aeroplane, etc.

CONSTITUTION: A cradle for equipment has a cooling-air intake port 4 and exhaust port 5 which communicate to the inside and each heat exchange surface 2 on tow surfaces in contact with the supported equipment, and a radiator 3 is arranged inside so as to contact the heat exchange surface 2. The cooling air is introduced inside from the taking-in port 4, and after cooling the radiator 3, the air is exhausted from an exhaust port 5. A fixing metal fitting 6 and a guide pin 7 are used for fixing the cradle body. The heat of the equipment is transmitted through the heat exchange surface 2, and cooled through the heat exchange with the cooling air which is introduced inside from the taking-in port 4 in the radiator 3 inside, and the cooling air which cools the radiator 3 is exhausted from the exhaust port 5.
