Hot and cold impact test chamber

 

Technical scheme and characteristics of hot and cold impact test chamber:

Summary of hot and cold impact test chambers:

Hot and cold impact test machines / temperature shock test machines use: electrical and electronic components, metals, chemical materials, automated components, communications components, defense industry, aerospace industry,BGA,

Ideal test tool for physical changes in PCB substrates, electronic chip ICs,semiconductor ceramics and polymer materials

Technical features of science and technology instruments:

(1) With disk USB recording, no loggers are required.

(2) Refrigerant servo valve flow calculus control  Save 30% of power.  

(3)  High temperature and high humidity testing to prevent dew, drip technology industry leader

(4) Low temperature operating state, heater does not participate in the work, through PWM technology control to adjust the refrigeration unit refrigerant flow and flow, refrigeration pipe, cold bypass pipe, hot bypass pipe three-way flow adjustment, to achieve automatic constant temperature of the studio. This approach reduces energy consumption by 40% at low temperatures

(5) Temperature synchronous lift slope control (IEC68-2-56, 68-2-30),nodrip, no dew.

(6) Refrigeration advantages:  traditional equipment low temperature control methods:refrigeration compressor start-stop control temperature (temperature fluctuations, serious impact on compressor life, phased out technology).

Refrigeration compressor constant operation and heating PID control (causing cooling capacity to offset heating to achieve dynamic temperature balance wastes a lot of power).

New  PWM cold control technology to achieve low temperature energy-saving operation: new PWM cold control technology to achieve low-temperature energy-saving operation

How the temperature impact test chamber is controlled:

Using low temperature and high temperature storage heat storage tank, damPERneeds to be opened according to  theaction, the hot and cold energy in the storage tank is imported into the test tank to achieve rapid temperature impact effect,  balanced temperature control system(BTC)and specially designed air-feeding cycle system to dynamic P.I.D  Control SSR, so that the heat added to the system is equal to the amount of heat loss,  so that long-term and stable use.
