Liquid hydrogen vaporizer and heat transfer simulation analysis method thereof

The invention discloses a liquid hydrogen vaporizer and a heat transfer simulation analysis method thereof, and relates to the related field of liquid hydrogen vaporizers, the liquid hydrogen vaporizer comprises a bottom rectangular frame, six same bottom connecting rods are fixedly arranged on the bottom rectangular frame, a small hole is formed in the side face of each bottom connecting rod, a top rectangular frame is fixedly arranged at the upper end of the bottom rectangular frame, and the top rectangular frame is fixedly provided with a top through hole. Six same top connecting rods are fixedly arranged on the top rectangular frame, each top connecting rod is provided with small holes which are the same as the small holes in the bottom connecting rods, and the bottom connecting rods correspond to the top connecting rods in the vertical position relation. The CFD modeling is carried out on the heat transfer process of the liquid hydrogen vaporizer, and the heat transfer process analysis is carried out on
