Problems solved by technology

[0003] Both of the aforementioned two types of equipment have the following disadvantages: (1) they are bulky and heavy, and are difficult to move flexibly. Generally, the compressors commonly used in manufacturing are larger than 80cm*100cm*120cm in size and weigh more than 50kg; (2) the investment cost is high, and a The market price of a compressor ranges from 100,000 to 800,000 RMB, and the market price of each compressor and heat flow meter commonly used in industrial-grade product manufacturing or experiments is about 200,000 RMB; (3) The heating / cooling speed is very slow Under normal circumstances, it takes about 20 minutes for the compressor to cool down from normal temperature 25 degrees Celsius to -40 degrees Celsius, then rise from -40 degrees Celsius to 85 degrees Celsius, and then return from 85 degrees Celsius to normal temperature 25 degrees Celsius. And during the preheating process, heat accumulation will have a great impact on the stability of the temperature of electronic products; (4) The accuracy of the temperature stabilization time is not high. In general, at the temperature of -40 degrees Celsius and 85 degrees Celsius, the temperature accuracy Not high, fluctuating temperature above 3 degrees Celsius; (5) It is difficult for enterprises to expand production in the middle and late stages. Due to the defects of (1) to (4) mentioned above in the existing equipment, subsequent expansion needs to re-arrange the production workshop, resulting in huge losses. and it takes a long time to plan

Therefore, the application of equipment provided in the existing high and low temperature environment has brought many difficulties to many optical communication and electronic product manufacturing companies in the process of rapid investment, growth, and replacement.

In addition, these two types of equipment also have serious problems of noise pollution and exhaust pollution.

[0004] With the gradual expansion of the scale of the enterprise, if the existing general-purpose compressor equipment or heat flow meter equipment is still used to provide high and low temperature environment for production activities, it will make it difficult to expand production capacity, causing significant waste and inconvenience to the rewiring layout of the production line. Loss, long expansion time and many other problems have been unable to meet the needs of optical communication product manufacturers, and there is an urgent need to develop a more integrated, miniaturized, portable, small investment and highly flexible temperature rise and fall adjustment instrument to support enterprises the rapid development of
