The invention relates to the field of refrigerator cars and accessories thereof, in particular to a vacuum box plate of a refrigerator car. The vacuum box body plate of the refrigerator car comprises a hollow mounting plate, a vacuum box body arranged in the hollow mounting plate, fixing plates arranged on the two sides of an inner cavity of the vacuum box body, and a supporting frame erected between the fixing plates. The supporting frame comprises a connecting rod and a plurality of supporting rods arranged at the end of the connecting rod in the circumferential direction. A plurality of positioning grooves are formed in the fixing plates; when the inner cavity of the vacuum box body is vacuumized, the end parts of the supporting rods are suitable for being propped against the groove bottom surfaces of the positioning grooves; the fixing plates are supported through the supporting rods and the connecting rods so as to support the interior of the vacuum box body, and the vacuum box body is prevented from deforming under the action of atmospheric pressure.
