XQ-1642 Thermal Shock Testing Machine 
I. Application Scope of the Thermal Shock Testing Machine; 
Place the battery in a heat box, and increase the temperature at a rate of (5 ± 2℃) per minute to 130℃ ± 2℃ and maintain this temperature for 30 minutes. Then remove the battery and return it to room temperature. During the test, the battery should not catch fire or explode. 
II. Main parameters of the thermal shock testing machine; 
1.Temperature range: Room temperature (or ambient temperature) to 200℃ 
2. Temperature stability: ±0.5℃ 
3. Temperature display accuracy: ±0.1℃ 
4. Temperature uniformity: ±2℃ 
5. Internal dimensions (width * height * depth): 500 * 600 * 500 mm 
6. Heating time: (5 ± 2) °C/min, (average heating, non-linear no-load) 
7. Power Supply: 3 Ampere, 220 Volts, 15 Amperes, 50 Hertz 
8. Power supply capacity: 6KW 
9. Dimensions (approximate): 700*600*1320mm (length*width*height) 
10. Weight (approximate): 100kg 
III. Advantages of the Thermal Shock Testing Machine; 
The outer box is made of cold-rolled steel plate with paint coating and insulated cotton, and the inner box is made of stainless steel plate. The same structure is also adopted on the box door. The tempered glass of the observation window is thickened to effectively prevent the damage to the box caused by possible explosions of the equipment. 
Explosion-proof door lock: The box door is equipped with an explosion-proof door lock. When the pressure inside the box is high, the door can automatically open to prevent the strong airflow from damaging the door. Additionally, the door can be opened again after the test is completed. 
IV. Structure of the Thermal Shock Testing Machine; 
Inner box material: Stainless steel sheet. 
Outer box material: Cold-rolled steel plate with paint finish. 
Insulation material: High-efficiency compressed glass wool. 
V. Operation of the Thermal Shock Testing Machine; 
This instrument is equipped with a forced air circulation system. The air source is driven by the rotation of the circulation motor, which then drives the fan wheel and passes through the electric heater. The hot air is sent into the oven through the air duct, thereby reducing energy loss and ensuring uniform temperature inside the oven. When the door opens or closes causing disturbances, this air circulation system can quickly restore the operating temperature value. It has inlet and outlet air ports, and the air circulation is smooth with fast air exchange, avoiding the situation where the concentration of flammable gas is too high and causes spontaneous combustion and explosion. 
VI. Notes for Thermal Shock Testing Machine; 
1.Before conducting the test, please make sure that the power supply is properly plugged in or connected. 
2. When the machine is in operation, it is strictly prohibited to get too close to it. 
3. The mechanical transmission parts must be maintained regularly. 
4. After the test is completed, it is necessary to ensure that the power supply has been turned off. 
5. It is strictly prohibited to use auxiliary corrosive liquids to clean the machine. Instead, rust-proof oil must be used. 
6. This testing machine must be used exclusively by one person. The machine must not be knocked on or occupied by anyone. 
7. The machinery must be grounded.
