Description

Technical Field

[0001] The invention relates to an environmental control liquid supply system, in particular to a highly integrated air-to-ground dual-purpose pod environmental control liquid supply system. Background Art

[0002] Small airborne pods are small in size, low in load-bearing capacity, low in electrical power, low in air density at high altitudes, and have poor heat dissipation conditions. The environmental control and liquid supply system of small pods is one of the key military airborne electronic systems, requiring the system to be simple and reliable, low in power consumption, light in weight, and applicable to a wide range of flight envelopes.

[0003] The first commonly used solution is the pod environmental control liquid supply system with vapor compression refrigeration. The working principle is that the environmental control system cools the coolant by evaporating Freon R-114 in the evaporator to absorb heat. The cooled coolant absorbs the heat of the electronic equipment in the pod, and the system condenser dissipates heat by ram air. The advantage is that it can meet the needs of high temperature control requirements and high temperature control accuracy. The disadvantage is that the system is complex, power consumption is high, and weight is large.

[0004] The second commonly used solution is the pod environmental control liquid supply system with ram air circulation cooling. The working principle is: the environmental control system uses the bleed air duct to introduce ram air, and the ram air exchanges heat with the coolant in the air-liquid heat exchanger. After the coolant temperature is reduced, it is pressurized and supplied to the electronic equipment by the environmental control system. Refrigeration turbines and recoolers can also be added as needed to meet the requirements of a wider flight envelope. The advantages are simple system, low power consumption, and light weight, and the disadvantages are poor temperature control accuracy.

[0005] The common disadvantage of the two commonly used solutions is that they only provide cooling capacity when flying at high altitudes, and cannot independently support the operation of cabin equipment when on the ground. When the pod electronic equipment is debugged or tested on the ground, the hatch must be opened to connect to the liquid cooling source, or an air-conditioning vehicle must be used to provide low-temperature ram air to cooperate with the environmental control system. This not only requires the addition of additional ground support equipment and increases the total system cost; the ground support work is time-consuming and can hardly meet the requirements of rapid startup and rapid response in wartime. Summary of the invention

[0006] The technical problem to be solved by the present invention is to avoid the deficiencies in the above-mentioned background technology and provide a highly integrated air-to-ground dual-purpose pod environmental control liquid supply system. Compared with the existing solutions, the present invention can provide cooling capacity both at high altitude and on the ground, and adjust the ram air intake volume according to the flight speed when working at high altitude to increase the cooling capacity of the system.

[0007] The technical problem to be solved by the present invention is achieved by the following technical solutions:

[0008] Provided is a highly integrated air-to-ground dual-purpose pod environmental control liquid supply system, comprising a liquid storage tank, a liquid supply pump, and an air-liquid heat exchanger. The liquid storage tank is placed horizontally, and the liquid outlet port of the liquid storage tank is located below the reflux port. The liquid supply pump is provided at the liquid outlet port of the liquid storage tank, and the liquid supply pump is connected to the liquid inlet port of the air-liquid heat exchanger 4 through a liquid delivery pipeline. The air-liquid heat exchanger 4 is located on one side of the liquid supply pump, and the return liquid port of the air-liquid heat exchanger 4 is connected to the reflux port of the liquid storage tank through a reflux pipeline.

[0009] Furthermore, a heat exchange heat pipe plate part for exchanging heat with electronic equipment is installed on the return pipeline.

[0010] Furthermore, the air vents on both sides of the air-liquid heat exchanger are respectively equipped with three-way air ducts 6 and bleed air ducts 5, and a one-way valve 7 and an electric control valve 8 are installed on the three-way air ducts.

[0011] Furthermore, an air intake fan is actually disposed on the inner side of the electric control valve.

[0012] Furthermore, a filter is installed at the liquid return port of the liquid storage tank.

[0013] The beneficial effects achieved by the present invention include:

[0014] 1. It can work both at high altitude and on the ground, without the need for ground support equipment, which reduces costs and improves the ability to start and respond quickly.

[0015] 2. The temperature control accuracy is high. By adjusting the opening of the electric control valve and the fan speed, the air intake volume of the air-liquid heat exchanger can be adjusted, thereby adjusting the temperature control accuracy to meet the needs of high-precision temperature control.

[0016] 3. The high-altitude heat dissipation capacity is strong. The suction effect of the fan increases the total inlet pressure of the ram air, thereby increasing the cooling capacity of the environmental control system, which can meet the heat dissipation of higher-power electronic equipment and a wider range of flight envelope work requirements.

[0034] The component combination features not described in detail in the specification belong to the content that is easily thought of by the known technology or easily determined and undisputed when implementing the present invention.

[0035] When working at high altitude: ram air enters the air-liquid heat exchanger through the bleed air duct, the one-way valve opens, and the controller controls the opening of the electric control valve and the speed of the fan. When the supply temperature is high, the opening and speed are increased to increase the air flow through the air-liquid heat exchanger and reduce the coolant temperature. When the supply temperature is low, the opening and speed are reduced to reduce the air flow through the air-liquid heat exchanger and increase the coolant temperature.

[0036] When working on the ground: the electric control valve opens, the fan works, and since the one-way valve can only be opened to exhaust air outside the cabin, it will not cause air flow short circuit. Under the action of the fan suction, air enters from the bleed air duct and is discharged from the fan to achieve the cooling function.
