Embodiment Construction

[0019] Such as figure 1 As shown, a thermal management device suitable for instantaneous high heat flow, including a flow control valve 1, a filter 2, an air-liquid hydrogen heat exchanger 3, a shut-off valve 4, a second shut-off valve 5, a fan 6, and a cockpit 7 , pump 8, liquid storage tank 9, electronic equipment 10, second power system 11, hydraulic system 12, liquid hydrogen fuel tank 13, pump 14, temperature control valve 15, engine 16.

[0020] The fuel in the liquid hydrogen fuel tank 13 works through the pump 14 , flows into the air-liquid hydrogen heat exchanger 3 and absorbs heat, and then enters the engine 16 .

[0021] Wherein, the ram air enters the air-liquid hydrogen heat exchanger 3 through the filter 2 to transfer heat to the liquid hydrogen fuel; the flow rate of the ram air is controlled by the flow control valve 1 , and its temperature is controlled by the temperature control valve 15 . When the aircraft stops on the ground, the air side of the air-liquid...

Abstract

The invention relates to a heat management device suitable for instantaneous high heat flow, comprising a flow control valve (1), a filter (2), an air-liquid hydrogen heat exchanger (3), a shut-off valve (4), a second shut-off Valve (5), fan (6), cockpit (7), pump (8), liquid storage tank (9), electronic equipment (10), the fuel in the liquid hydrogen fuel tank (13) acts through pump (14), After flowing into the air-liquid hydrogen heat exchanger (3) and absorbing heat, it enters the engine (16). The invention uses ram air to realize the cabin air conditioning function, and the system structure is simple; the single-phase liquid circuit system is used to effectively take away the concentrated heat load of the electronic equipment, the second power system and the hydraulic system; the liquid storage tank is used to immerse in the liquid hydrogen fuel tank Acts as a "thermal buffer" to effectively cool transient high heat flow heat loads.

Description

Technical field [0001] The invention belongs to the field of aircraft environment control. Background technique [0002] At present, the main technologies applied in the field of aircraft environment control at home and abroad include air circulation cooling technology, evaporative circulation cooling technology and liquid loop cooling technology. [0003] Air circulation cooling technology is widely used in various types of aircraft environmental control systems, but the coefficient of cooling performance is low, the reliability of the system is poor when the ground is stopped, and because the introduction of external ram air, the operating height and speed are limited to a certain extent , These all form a contradiction with the characteristics of severe aerodynamic heating, high flight altitude and high speed of hypersonic vehicles. [0004] Evaporative cycle cooling technology has the following characteristics: high coefficient of performance, good economy; small relati...
