Tianjin Thermal Shock Testing Machine

The cold and hot shock test chamber is divided into three parts: high temperature zone, low temperature zone, and testing zone. The test sample is placed in the testing zone * and is stationary. The heat storage and cold storage structure of * is adopted, and the forced cold and hot air path switching method is introduced into the testing zone to complete the cold and hot temperature shock test;

1Tianjin Thermal Shock Testing MachineThe shell is made of SCCE steel plate with electrostatic spraying or stainless steel brushed plate, which is beautiful, flat, atmospheric, with a curved design, smooth and natural lines, reasonable design, and durable.

2. Interior wall of the studio: Made of high-quality 304 mirror stainless steel material, processed and formed using domestically advanced processing equipment.

3. Insulation layer: Hard PU foam and aluminum silicate cotton are used. Aluminum silicate cotton has the characteristics of high temperature resistance and low heat transfer coefficient compared to similar glass fiber cotton. The thickness of the insulation layer is 100mm, ensuring that the temperature inside the test room will not be transmitted to the outside of the equipment, making the test temperature more accurate.

4. The box is equipped with a diameter of 50mm, test holes, and sealed with foam silicone plugs. It can be used for external testing of power or signal lines.

5. The bottom of the machine adopts high-quality fixed PU movable wheels with horizontal feet attached.

6. It can independently set three different conditions: high temperature, low temperature, and thermal shock, and has the function of a high and low temperature testing machine.

7. The number of cycles and defrosting times can be set for automatic (manual) defrosting The air outlet is detected and controlled by the return air outlet sensor, and the switching time of the air door mechanism is completed within 10 seconds.

8. Equipped with fully automatic and high-precision system circuits, any component action is locked and processed by P.L.C, and all are controlled by P.I.D automatic calculation.

The temperature recovery time is completed within 5 minutes.

When an abnormal situation occurs during operation, the screen will automatically display the cause of the fault, and an emergency stop device will be installed when unstable input power is detected.

11. Optional USB interface for convenient storage, with standard RS-232 or RS-485 computer communication interfaces available. Implement remote control.

Model explanation: For example, BY-260D-100A refers to a thermal shock testing machine with a temperature range of -10 ℃~-40 ℃ and an inner box of 100L

100A bit - volume and temperature range inside the box (corresponding number represents the volume of the box, unit: L)

The letter represents a range of -10 ℃ to -40 ℃ (type A); -10 ℃~-55 ℃ (Type B); -10~-60 ℃ (Type C)

Note: The outer box size of the test chamber is adjusted according to the selected appearance.

The product meets the requirements of GB/T2423.1-2008 Test A, GB/T2423.2-2008 Test B, GB-T10592-2008, GJB150.3-198, GJB360A-96 Method 107 Temperature Shock Test.

Cold and hot shock testing machines are divided into three box and two box types according to testing requirements and standards, with differences in testing methods and internal structures.

The test box adopts a multi wing air supply fan strong air circulation system to avoid any dead corners and ensure uniform temperature distribution in the testing area.

The design of wind path circulation for air outlet and return ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature at the moment of opening the door.

Refrigeration system and compressor: This experiment uses a set/single French "Taikang" or German "Bizelle" fully enclosed or semi enclosed unit/binary cascade refrigeration system compressor

Refrigerant: Adopting environmentally friendly refrigerants R404A (low-pressure cycle) and R23 (high-pressure cycle) produced by DuPont in the United States.

Refrigeration auxiliary components: expansion valve (Denmark); Electromagnetic valve (Japan); Filter (Denmark); Pressure controller (Denmark); Oil pressure protection (Denmark) and auxiliary components such as oil separators (Europe and America).
