Abstract

The invention discloses an efficient low-temperature vibration vaporizer which comprises a bottom plate, a back plate is arranged above the bottom plate, a heat exchange vaporization unit composed of heat exchange pipes is fixed to the back plate, and a medium inlet and a medium outlet of the heat exchange vaporization unit are each provided with a low-temperature-resistant hose used for being connected with a hydrogen supply system. The back plate is installed on the bottom plate through a plurality of elastic assemblies, and the back plate and the heat exchange vaporization unit can shake relative to the bottom plate through the elastic assemblies under the action of natural excitation or forced excitation. The heat exchanger has the advantage of high heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of cryogenic vaporization, in particular to a vibration type liquid hydrogen vaporizer applied to the new energy vehicle industry. Background technique [0002] Liquid hydrogen can greatly increase the density of hydrogen storage, increase the cruising range of hydrogen energy vehicles, and at the same time greatly reduce the restrictions on installation. It is considered to be the most promising hydrogen storage method. The vaporizer is an important component of a hydrogen energy vehicle. It mainly uses natural convection or forced convection for heat exchange to vaporize liquid hydrogen into gaseous hydrogen for hydrogen energy vehicles. The structure of the currently used vaporizer includes: a bottom plate, a back plate is fixed on the bottom plate by bolts, a heat exchange vaporization unit composed of heat exchange tubes is fixed on the back plate, and the medium inlet and medium outlet of the heat exch...
