Object.Ortho-hydrogen and parahydrogen are two kinds of spin isomers of molecular hydrogen, and parahydrogen is identical with the chemical property of ortho-hydrogen, and physical property
Difference.In room temperature or when being higher than room temperature, just, the equilibrium composition of parahydrogen ratio be 75:25, referred to as standard hydrogen (n-H2) or normal
Hydrogen.When lower than room temperature, just, the equilibrium composition of parahydrogen ratio will change, percentage shared by parahydrogen increase.Gaseous Hydrogen it is just secondary
State conversion could occur in the presence of a catalyst, and liquified hydrogen then will spontaneously be sent out in the case where no catalyst
Raw just secondary conversion, but conversion rate is slower.The just secondary conversion of hydrogen is an exothermic reaction, the heat released in conversion process and conversion
When temperature it is related.Liquid hydrogen evaporation loss caused by heat release is converted to reduce positive parahydrogen, requires parahydrogen to contain in all liquid hydrogen products
Amount requires to be substantially all ortho-hydrogen when liquefaction to be catalytically conveted to parahydrogen at least 95% or more.When preparing liquid hydrogen, need in gas
Be about to begin n- parahydrogen conversion when state hydrogen.
Have now can be provided for gaseous state liquefaction of hydrogen the ice chest of cooling capacity with can for the ice chest that the n- parahydrogen of Gaseous Hydrogen converts, but
It is not have the ice chest that can be provided cooling capacity simultaneously for gaseous state liquefaction of hydrogen and can convert for the n- parahydrogen of Gaseous Hydrogen now.

A kind of the advantages of the utility model are as follows: ice chest use with n- parahydrogen transformation function described in the utility model
More air-flow sunk type shell-and-tube heat exchanger design concepts, so that the n- parahydrogen conversion of hydrogen_cooling and hydrogen can be synchronous in ice chest
It carries out, and also absorbs the heat generated in n- parahydrogen conversion process, solve temperature in n- parahydrogen conversion process and maintain
Problem.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the ice chest with n- parahydrogen transformation function described in the utility model.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
As shown in Figure 1, a kind of ice chest with n- parahydrogen transformation function, comprising: shell 1 is provided with shell on shell 1
Body entrance 11 and housing outlets 12, cold source can be flowed into shell 1 by housing inlet port 11, and can be flowed by housing outlets 12
Shell 1 out, in the present embodiment, cold source are usually liquid nitrogen；It is additionally provided with a combined type heat exchanger tube 2, combined type within the case 1
The heat exchange tube inlet 24 and heat transfer tube outlet 25 of heat exchanger tube 2 stretch out shell 1 respectively, and combined type heat exchanger tube 2 includes one section of helical coil
Bent heat exchanger tube 21 and one section of straight heat exchanger tube 22, helix-coil heat exchanger tube 21 is located on the outside of straight heat exchanger tube 22, in straight heat exchanger tube
