The invention discloses a self-adaptive combined self-pressurization expansion box of an airborne liquid cooling system. Comprising an expansion shell (1), an inner cavity of the expansion shell (1) is divided into a liquid storage cavity (3) and a static pressure cavity (4) through a large piston (2), the static pressure cavity (4) is communicated with the atmosphere, and an outlet of the liquid storage cavity (3) is communicated with a liquid cooling pump inlet (22); a pressurizing cavity (6) is further formed in the side, close to the static pressure cavity (4), of the large piston (2), and a small piston (7) and a reset spring (8) are arranged in the pressurizing cavity (6). The liquid cooling pump outlet (20) is communicated with the booster cavity (6) through the liquid guide pressure stabilizer (9), and the booster cavity (6) is further communicated with the liquid cooling pump inlet (22) through the sizing hole (10). According to the invention, under the conditions of different flight heights, different outlet pressure changes, different loads and different flows, the self-pressurization pressure of the airborne liquid cooling system can be stabilized in a specified pressurization value (100-200) kPa (absolute pressure) range.

    本发明公开了一种机载液冷系统自适应组合自增压膨胀箱。包括膨胀壳体(1),膨胀壳体(1)的内腔经大活塞(2)被分隔为储液腔(3)和静压腔(4),静压腔(4)与大气连通,储液腔(3)出口与液冷泵入口(22)连通;大活塞(2)靠近静压腔(4)一侧还设有增压腔(6),增压腔(6)内设有小活塞(7)和复位弹簧(8);液冷泵出口(20)经引液稳压器(9)与增压腔(6)连通,增压腔(6)还经定径孔(10)与液冷泵入口(22)连通。本发明可以在不同飞行高度、不同的出口压力变化,不同载荷及不同流量下,均能保证机载液冷系统的自增压压力稳定在规定的增压值(100~200)kPa(绝对压力)范围内。
