Abstract

The invention provides a spiral coil heat exchanger structure for a nuclear energy and chemical energy hybrid engine. The spiral coil heat exchanger structure comprises an inner pipe body, an outer pipe body and a plurality of groups of spiral coil bundles adopting high-temperature alloy formed by 3D printing processing; the outer pipe body sleeves outside the inner pipe body; a liquid metal inlet and a liquid metal outlet are formed in the two ends of each spiral coil bundle correspondingly, each group of spiral coil bundles is located between the outer pipe body and the inner pipe body, and each group of spiral coil bundles sleeves outside the inner pipe body; and the liquid metal inlets and the liquid metal outlets both extend out of the outer pipe body.

Description

technical field [0001] The disclosure relates to the technical field of nuclear reactor heat exchangers, in particular to a spiral coil heat exchanger structure and a nuclear energy and chemical energy hybrid engine with the spiral coil heat exchanger structure. Background technique [0002] Nuclear aero-engines are engines that use the huge energy generated by nuclear fuel fission to power aircraft. Aircraft equipped with nuclear aero-engines have the advantages of ultra-long range and long flight time, and can fly to any place on the surface of the earth without refueling in the air. places, the stay in the air can exceed 1 month. The aeroengine with a mixed cycle of nuclear energy and chemical energy is mainly aimed at nuclear safety, and adopts a mixed cycle mode of chemical energy for ground takeoff and nuclear energy for air cruise. [0003] The heat exchanger is the heat conversion hub of the nuclear reactor, but in the prior art, there is no heat exchanger applied t...
