In a cooling cabinet equipped with a cooling chamber that allows for the loading and unloading of carts carrying objects to be cooled, and a differential pressure unit that creates a differential pressure within the cooling chamber, the risk of cleaning water directly contacting the inner surface of the differential pressure unit is eliminated, thereby improving the efficiency of cleaning the cooling chamber. [Solution] The differential pressure unit 6 comprises a hollow differential pressure duct 15 having a cold air intake port 17 and an outlet port 18, a differential pressure fan 16 that forms an airflow from the intake port 17 to the outlet port 18 within the differential pressure duct 15, and a wind direction guide 21 provided on the outer surface side of the intake port 17 of the differential pressure duct 15. This wind direction guide 21 is configured to be displaceable between an open position facing the side of a cart 30 placed in front of the intake port 17 and a closed position that blocks the intake port 17.

This invention discloses a rotating disk cavity test platform, comprising a main air intake system, a cold air intake system, an exhaust system, a power transmission system, a lubrication system, and a cooling water system. The main air intake system is connected to the test piece and provides the test piece with the required flow rate, temperature, and pressure of the main airflow. The cold air intake system is connected to the test piece and provides the test piece with the required flow rate, temperature, and pressure of the secondary airflow. The exhaust system is used to exhaust gas from the test piece, and the main air intake system and the cold air intake system are respectively connected to the exhaust system. The power transmission system is used to drive the rotation of the test piece. The lubrication system is used to lubricate the test piece and the power transmission system. The cooling water system is connected to the lubrication system and is used to dissipate heat from the lubricating oil in the lubrication system. This test platform introduces modeled main and secondary flows under high-speed rotation conditions to conduct rotating disk cavity flow and heat transfer tests, studying the effects of different engine speeds and variations in secondary flow rate / temperature / pressure parameters on disk cavity flow and heat transfer.
