Heat shock testing equipment

Technical parameters required :

1 Studio Size (cm):bigger than 50 * 50 * 50, a cabinet

2 Temperature range: -75 celsius degree ~ 220 celsius degree

3 Temperature uniformity: less than 2.0 celsius degree

5 humidity deviation: about 3 percent (bigger than 75 percent RH), about 5 percent (less than 75 percent RH)

6 heating rate:bigger than 30 celsius degree / min

7 cooling rate:bigger than 30 celsius degree / min

8 Minimum load: 50KG

Cabinet Material :

1.high temperature chamber box made of CNC machining , nice shape, and no reaction handle , easy to operate .

2.high temperature chamber of imported high grade stainless steel inner tank (SUS304) mirror panels ,cabinet outside the gall (SUS304) brushed stainless steel or high-quality cold-rolled steel spray , increasing the appearance of texture and cleanliness.

3 high- temperature chamber with a large observation window with bright lights to keep the box , and the use of heating element embedded glass, clear observation box at any condition .

4.The left side of the box with high and low temperature test diameter (25mm, 50mm, 100mm optional ) test holes for external test power line or signal line.

5 high and low temperature insulation material made of high density fiberglass thickness of 80 ~ 100mm. Using double sheets of high resistance, high temperature resistance seal between the door and the cabinet to ensure that the seal test area .

Cooling Principle:

Refrigeration equipment is part of the main part of the cold source , to provide the required cooling capacity of the cooling equipment , and other low and constant temperature , the device according to the type of test condition , the refrigeration system automatically open to provide cooling for the corresponding test process, thereby to meet performance targets to achieve the purpose of the device .

Design of the refrigeration system energy application control technology , an effective treatment can ensure both energy and cooling capacity of the cooling system is adjusted in the case of the normal operation of the refrigeration unit , so that operating costs of the refrigeration system drops to more economical condition.

Cooling system components:

Compressor: core cooling system is the compressor , we use two sets of this program , " Copeland " (DWMCOPELAND) semi- hermetic scroll compressors , consisting of a cascade refrigeration system to ensure that the cooling requirements of the studio . A cascade system comprising a low pressure of the refrigeration cycle and the refrigeration cycle , the container is connected evaporator, condenser, evaporator function as a condenser of the low pressure circulation loop used.

Control Systems

1.Display: set temperature ; measured temperature ; heating time, temperature curves and other working conditions as well as various alarm indication.

2.Setting Accuracy : Temperature : 0.1 celsius degree

3.Program Capacity: 100 , the single largest step 99 -step program , the largest single-step procedure time : 99 hours 59 minutes ; may link between the program ;

4.Interface : RS485, and with the corresponding software

5.Run mode: Constant running , the program runs ;

6.Other major low-voltage electrical components are well-known brands: Schneider AC contactor, thermal overload relay , OMRON small middle Relays ,lights and switches, circuit breakers West Germany , Taiwan, where appropriate electronic float type level controller .
