Test environment control system

A test environment control system, comprising:

• a pressure-resistant container including a gas storage room and a control valve that is in spatial communication with the gas storage room, wherein the gas storage room is configured to store a dry gas that has a dew point temperature being less than −10° C. and that has a pressure being greater than 1 atm;
• a temperature control device at least partially arranged in the gas storage room and immersed in the dry gas, wherein the temperature control device is configured to control the dry gas in the gas storage room to arrive at a predetermined temperature;
• and
• a plurality of contactless test devices connected to the control valve of the pressure-resistant container, wherein the control valve of the pressure-resistant container is configured to output the dry gas having the predetermined temperature from the gas storage room to a N number of the contactless test devices, selectively, for establishing a predetermined test environment in each of the N number of the contactless test devices, and wherein N is a positive integer;
• wherein the pressure-resistant container includes a first pressure-resistant tank and a first output pipe that connects the first pressure-resistant tank and the control valve, and an interior space of the first pressure-resistant tank is defined as at least part of the gas storage room, and wherein the temperature control device includes a cooling mechanism that is at least partially arranged in the first pressure-resistant tank for reducing a temperature of the dry gas in the first pressure-resistant tank.

• wherein the temperature control device includes:
• a first heat exchanger at least partially arranged in the gas storage room and immersed in the dry gas, wherein the first heat exchanger has a first cooling critical value;
• and
• a second heat exchanger at least partially arranged in the gas storage room and immersed in the dry gas, wherein an operation power of the second heat exchanger is higher than an operation power of the first heat exchanger, and the second heat exchanger has a second cooling critical value that is less than the first cooling critical value;
• wherein the temperature control device is configured to reduce a temperature of the dry gas in the gas storage room to the first cooling critical value through the first heat exchanger, and then further to reduce the temperature of the dry gas from the first cooling critical value through the second heat exchanger.
