Abstract
The invention relates to the technical field of cooling devices, in particular to an anti-freezing supercooling device and a rocket. The anti-freezing supercooling device comprises a supercooling box suitable for containing a cooling medium, and the cooling medium has a gas state and a liquid state; the heat exchanger is arranged in the supercooling box and placed in the cooling medium in the liquid state, and a medium to be cooled is suitable for being introduced into the heat exchanger; the booster pump is connected with the inlet end of the supercooling box and is suitable for injecting a supercharged cooling medium into the supercooling box; and the pressure control module is suitable for detecting the pressure in the supercooling box and controlling the rotating speed of the booster pump according to the detected pressure value. According to the anti-freezing supercooling device, the booster pump is arranged to inject the supercharged cooling medium into the supercooling box, the supercharged cooling medium is saturated, the temperature is increased, freezing of the to-be-cooled medium is avoided, the booster pump and the supercooling box only need to be communicated through a simple pipeline, the structure is simple, and operation is convenient. The anti-freezing supercooling device is small in number of pipelines and simple in structure.
Description
technical field [0001] The invention relates to the technical field of cooling devices, in particular to an anti-freezing supercooling device and a rocket. Background technique [0002] With the development of aerospace technology, low-temperature launch vehicles are gradually moving towards commercialization, and liquid methane as a fuel propellant has received more and more attention. The thermodynamic properties of liquid methane can be improved by supercooling, increasing its own density, Reducing the saturation pressure, etc., thereby increasing the payload of the rocket has great application value. In the prior art, liquid nitrogen is often used as the cooling medium, and liquid methane is cooled by exchanging heat between liquid nitrogen and liquid methane. However, the cooling of liquid methane needs to be moderate. In the process of supercooling liquid methane, if liquid If the temperature of nitrogen is too low, it will cause liquid methane to freeze, which will c...
