[0002] The ground cooling device of the aircraft liquid cooling system is designed to connect the air-conditioning vehicle with the aircraft for rapid cooling when an air-conditioning vehicle is used instead of a liquid cooling vehicle for field maintenance of the liquid cooling system.

[0003] At present, most of the station facilities are not directly equipped with liquid cooling vehicles. During field maintenance, ground air-conditioning vehicles are needed to cool the liquid cooling system. However, ground air-conditioning vehicles cannot be connected to the air inlet of the liquid cooling system, so the liquid cooling system cannot be directly cooled by ground air-conditioning vehicles. At this time, it is necessary to use special liquid cooling equipment to cool the liquid cooling system, but the special liquid cooling equipment will greatly prolong the maintenance time and have low efficiency. Summary of the invention

[0004] In order to solve the technical problem that the liquid cooling system cannot be directly cooled by the ground air conditioning vehicle in the related art, and the borrowing of special liquid cooling equipment will greatly prolong the maintenance time and have low efficiency, the present invention provides a ground cooling device for the aircraft liquid cooling system, which is easy to disassemble and assemble, easy to operate, and saves maintenance time. This device can quickly realize the cooling of the liquid cooling system, save maintenance time, and does not need to borrow special liquid cooling equipment. The technical solution is as follows:

[0009] Furthermore, the pressing block is provided with a strip hole along the longitudinal direction for allowing the screw to pass through. The pressing block can be moved up and down according to the edge thickness of the aircraft liquid cooling system air inlet, ensuring that the flange is tightly fixed to the edge of the aircraft liquid cooling system air inlet to prevent gas leakage when providing cold air to the liquid cooling system.

[0010] in,

[0011] The flange consists of two parts, one is the base, and the other is the protrusion embedded in the air inlet of the aircraft's liquid cooling system. The two parts are formed as a whole through machining.

[0012] Optionally, the first straight pipe, the 90° elbow pipe, the second straight pipe, and the flange are made of high-strength aviation aluminum. This design makes the equipment high in strength, light in weight, and easy to carry around.
