Baffle plate assembly for directing air flow in a cargo container
View Patent ↗A cargo container has a top, bottom, and sides. The cargo container includes a ventilation unit having an air outlet. The cargo container also includes a ventilated floor, which has an air channel, and a baffle plate assembly configured to direct air from the air outlet of the ventilation unit into the air channel of the ventilated floor. The baffle plate assembly includes a first plate, which is attached to the bottom of the cargo container to remain fixed, and a second plate, which is hinged to the first plate to move from an open position to a closed position. When the second plate is in the open position, a gap between the air outlet of the ventilation unit and the air channel of the ventilated floor is exposed. When the second plate is in the closed position, the gap between the air outlet of the ventilation unit and the air channel of the ventilated floor is covered.

a baffle plate assembly configured to direct an airflow from the air outlet of the ventilation unit into the air channel of the ventilated floor, wherein the baffle plate assembly is located upstream of the ventilated floor in the direction of airflow, and wherein the baffle plate assembly comprises:
a first plate attached to the bottom of the cargo container to remain fixed; and
a second plate hinged to the first plate to move from an open position to a closed position, wherein the second plate pivots away from the bulkhead to move from the closed position to the open position, such that to remain in the open position, the second plate does not need to be held open,
wherein a gap between the bottom air outlet of the ventilation unit and the air channel of the ventilated floor is exposed when the second plate is in the open position, and
wherein the gap between the bottom air outlet of the ventilation unit and the air channel of the ventilated floor is covered when the second plate is in the closed position.
2. The cargo container of claim 1 , wherein the bottom air outlet is disposed at a bottom portion of the bulkhead near the ventilated floor.
3. The cargo container of claim 2 , wherein the second plate contacts the bulkhead when the second plate is in the closed position.
4. The cargo container of claim 3 , wherein the second plate includes a gasket disposed along an edge of the second plate, wherein the gasket contacts the bulkhead when the second plate is in the closed position.
5. The cargo container of claim 1 , further comprising:
a plurality of supports attached to the bottom of the cargo container, wherein the plurality of supports are distributed in the gap between the bottom air outlet of the ventilation unit and the air channel of the ventilated floor, and wherein the first plate is attached to the plurality of supports.
6. The cargo container of claim 1 , wherein the second plate is positioned over the first plate when the second plate is in the open position.
7. The cargo container of claim 1 , wherein the ventilated floor comprises:
a plurality of beams, wherein the air channel is defined between the beams of the ventilated floor.
8. The cargo container of claim 1 , wherein the baffle plate assembly further comprises:
a plurality of hinges attached to the first plate and the second plate.
9. The cargo container of claim 1 , wherein the second plate is bent to have a first portion and a second portion, and wherein the first portion is substantially horizontal and the second portion is substantially vertical when the second plate is in the closed position.
10. A baffle plate assembly for use in a cargo container having a top, bottom, and sides, the cargo container having a ventilation unit and a ventilated floor, wherein the ventilation unit includes a bulkhead, a top air inlet and a bottom air outlet, the baffle plate assembly comprising:
a first plate configured to be attached to the bottom of the cargo container to remain fixed; and
a second plate hinged to the first plate to move from an open position to a closed position,
wherein the second plate pivots away from the bulkhead to move from the closed position to the open position, such that to remain in the open position, the second plate does not need to be held open,
wherein a gap between the bottom air outlet of the ventilation unit and an air channel of the ventilated floor is exposed when the second plate is in the open position, and
wherein the gap between the bottom air outlet of the ventilation unit and the air channel of the ventilated floor is covered when the second plate is in the closed position to direct an airflow from the bottom air outlet of the ventilation unit into the air channel of the ventilated floor, and wherein the baffle plate assembly is located upstream of the ventilated floor in the direction of airflow.
11. The baffle plate assembly of claim 10 , further comprising:
a plurality of supports attached to the bottom of the cargo container, wherein the first plate is attached to the plurality of supports.
12. The baffle plate assembly of claim 10 , wherein the second plate is bent to have a first portion and a second portion, and wherein the first portion is substantially horizontal and the second portion is substantially vertical when the second plate is in the closed position.
13. A method of installing a baffle plate assembly in a cargo container having a top, bottom, and sides, the cargo container having a ventilation unit and a ventilated floor, wherein the ventilated unit includes a bulkhead, a top air inlet, and a bottom air outlet the method comprising:
obtaining the baffle plate assembly, the baffle plate assembly having
a first plate, and
a second plate hinged to the first plate to move from an open position to a closed position, wherein the second plate pivots away from the bulkhead to move from the closed position to the open position such that to remain in the open position, the second plate does not need to be held open; and
attaching the first plate to the bottom of the cargo container to remain fixed, wherein the baffle plate assembly is located upstream of the ventilated floor in the direction of airflow after the baffle plate assembly is installed,
wherein a gap between the bottom air outlet of the ventilation unit and an air channel of the ventilated floor is exposed when the second plate is in the open position after the baffle plate assembly is installed, and
wherein the gap between the bottom air outlet of the ventilation unit and the air channel of the ventilated floor is covered when the second plate is in the closed position to direct an airflow from the bottom air outlet of the ventilation unit into the air channel of the ventilated floor after the baffle plate assembly is installed.
14. The method of claim 13 , wherein attaching the first plate to the bottom of the cargo container comprises:
attaching a plurality of supports to the bottom of the cargo container; and
attaching the first plate to the plurality of supports.
