Compatible airplane liquid cooling device

Abstract

The invention relates to a compatible airplane liquid cooling device suitable for refrigerating of heating devices of different types of airplanes. The compatible airplane liquid cooling device is mainly composed of a power distribution unit, a controller unit, an operation panel, a hydraulic unit and a refrigerating unit. The controller unit is used for controlling flow, pressure, temperature and the like so that the compatible airplane liquid cooling device can produce needed flow and pressure. The hydraulic unit is mainly formed in the manner that a plurality of sets of hydraulic loops suitable for the different types of airplanes share one concentration oil tank and one set of refrigerating unit, and redundancy exists between the hydraulic loops. The refrigerating unit is used for cooling branches of the concentration oil tank, and is mainly composed of a heat exchanger, a refrigerating compressor, an evaporator, a liquid storage device, a gas-liquid converter and a gas-liquid separator. Compared with the prior art, the multiple sets of parallel hydraulic refrigerating loops can be arranged in the large concentration oil tank, and oil supplying and refrigerating can be achieved on the various airplanes.

Description

technical field [0001] The invention belongs to aviation support equipment, and specifically relates to a compatible liquid cooling equipment. The equipment includes mechanical, hydraulic, and electrical technical fields, and involves variable flow control, bypass cooling, compressor refrigeration, and large load control strategies. redundant design, etc. Background technique [0002] With the development of my country's aviation and national defense, the functions and performance of the aircraft have been improved to varying degrees, and the heat generated by the internal electronic equipment has gradually increased. The heat dissipation of the equipment itself cannot meet the environmental requirements of the equipment, so cooling equipment is needed to cool the internal electronic equipment of the aircraft. When the aircraft is in flight, it is cooled by the external air field and the cooling equipment inside the aircraft. However, when the aircraft is inspected, overhau...

[0007] Second, variable flow control should be selected to meet the needs of various flow and pressure parameters. The hydraulic variable control in the prior art generally adopts proportional valve control or proportional pump control, but these two methods are clean for the oil. There is a high requirement for the cleanliness of the cooling medium in the aircraft, but the cleanliness requirements for the cooling medium in the aircraft are not high, which belongs to the cleanliness requirements of conventional valves. Using proportional valves or proportional pumps will artificially increase the cleanliness requirements of the cooling medium and increase the equipment. risk of failure, so low-cost measures that can achieve variable flow control

[0008] Third, due to the singleness of the corresponding models of traditional liquid cooling equipment, its pipeline requirements are simple and often only have a set of pipelines for liquid outlet and liquid return. The cooling components are arranged near the liquid outlet of the liquid cooling equipment to cool the pipeline; Compatible liquid cooling equipment has multiple sets of pipelines corresponding to various models. If this method is continued to configure each set of output pipelines with cooling components of corresponding power, although the basic functions can be realized, the equipment will be bulky and expensive. High efficiency, low efficiency and other issues, so centralized cooling measures are needed

[0009] Fourth, when considering changing the location and method of refrigeration components and hoping to use a group of refrigeration components to meet the output of multiple pipelines, it will lead to problems with the control stability and temperature control accuracy of this group of refrigeration components
