Abstract

The invention provides a temperature control system for a high-pressure gas preparation device. The control system comprises a gas storage device storing pressurized gas; a first branch communicating with the gas storage device and a workpiece; a temperature adjusting branch which arranged on the first branch and comprises a second branch and a third branch which are arranged in parallel, wherein a heating device is arranged on the second branch, and a low-temperature cooler is arranged on the third branch; and a control unit. The temperature control system of the invention can be used for directly preparing high-pressure gas with adjustable temperature, and has the functions of heating and cooling the gas.

Description

technical field [0001] The present invention relates to the field of gas preparation devices, and in particular to a temperature control system and control method for high-pressure gas preparation devices Background technique [0002] In order to simulate the real working state of the workpiece as much as possible, it is necessary to use gas media at different temperatures to carry out relevant tests. Currently, liquid gas is generally used to obtain the required gas in the form of heating and vaporization, but the temperature adjustment of the gas obtained by this method is not accurate, the pressure is not up to standard, and the reliability is not high, and the design intention is not perfectly realized. [0003] Chinese patent CN103033076A discloses a high-pressure, large-flow, low-temperature, liquid nitrogen / helium heat exchange device. The device uses liquid nitrogen to cool the helium to obtain the low-temperature helium required by the pressurized delivery test sys...
