Free QuoteThe thermal shock test chamber is also called the temperature shock test chamber and the high and low-temperature shock test chamber.
The two-zone thermal shock test chamber has two independently controlled high-temperature zones and low-temperature zones, one zone is above the other, and only the basket moves between the two zones to test the adaptability of products to rapid temperature changes.
The three-box test chamber is where the test product is in a fixed working area. By opening the air duct in the high and low-temperature areas, the high and low temperatures are introduced into the studio to test the high and low-temperature impact of the test product.
The thermal shock test chamber is suitable for aerospace, electronic instruments, materials, electricians, vehicle metals, electronic products, wires and cables of various electronic components, etc.
Two-zone hot cold thermal shock test chambers, through the heating system and refrigeration system of the unit, respectively generate a high-temperature environment and a low-temperature environment, but the test object into the designated chamber, and when the two chambers reach the preset temperature and are stable, the transmission The mechanism pulls the load basket to realize the movement of the components under test in the basket between the high and low chambers.
During the moving process, the high and low chambers are connected, and the tested components also enter another chamber from high temperature or low temperature, so a large amount of cold and heat air will be brought in, and the unit must quickly be restored to the predetermined temperature of each chamber through the refrigeration system or heating system.
When the temperature of the chamber where the component is under test is kept stable for a long time, the load basket will be reversely driven by the transmission mechanism to bring the component under test back to the original chamber. It must also quickly return to the predetermined temperature. Repeat the above operation to complete multiple temperature cycle impact tests.
The high and low-temperature thermal shock test chamber is widely used in electronic and electrical components, automation components, communication components, auto parts, metal, chemical materials, plastics, and other industries, defense industry, aerospace, military industry, BGA, PCB base plate, electronic chips The physical changes of IC, semiconductor ceramics and polymer materials, test the repeated tensile force of the material to high and low temperature and the chemical change or physical damage of the product during thermal expansion and contraction, to confirm the quality of the product, from the precise IC To the components of heavy machinery, it can be used as the basis or reference for its product improvement.

The two-zone equipment is divided into two parts: high-temperature area and low-temperature area. The test product is placed in the basket, and the basket moves the test product into the high-temperature area or low-temperature area during impact. The impact test product is dynamic.
The explosion-proof door handle with an automatic lock function ensures the safety of the operator during the test.
The large and bright see-through window uses the built-in electric heating heater and three-layer vacuum-coated glass to prevent water vapor or condensation from condensing water, without the need for wipers to remove fog, and to maintain a clear observation of the conditions in the test chamber at any time.
The cabinet is insulated with rigid polyurethane foam or ultra-fine glass fiber wool
It adopts a pull-out water tank with a buoyancy ball. When the water in the water tank reaches a certain water level, an alarm device will be issued to remind the operator to add water.
The outer box material is sprayed with anti-rust cold-rolled plate, which is exquisite and corrosion-resistant, and the inner box is made of SUS304 stainless steel. The product can be tested with electricity.
The diameter of the test hole is 50mm, which can be connected to the test power line and signal line to prevent the signal line from slipping and the silicone plug will be placed in the test hole during the test.
The control system adopts a 7-inch high-definition touch screen, a pure English operating system, and is equipped with a USB interface to connect with a computer, set parameters, and print data.
The direction of the universal wheel can be adjusted freely, which is convenient for the tester to move during the test, which saves time and effort.

In the interlayer of the air duct at one end of the working room, heaters, refrigeration evaporators, fan blades and other devices are distributed; the fan is used to circulate the air in the box. When the fan rotates at a high speed, the air in the working room is sucked into the air duct from the middle. After cooling, it is blown out from the side of the air duct, and the air after heat exchange with the test product in the studio is sucked into the air duct and circulated repeatedly to meet the temperature setting requirements.
Cold and heat shock test chamber refrigeration system
The refrigeration part is the main part of the equipment that generates the cold source, which provides the required cooling capacity for the cooling, low temperature and constant temperature of the equipment. The purpose of meeting the performance indicators of the equipment. The design of the refrigeration system uses energy regulation technology. An effective treatment method can not only ensure the normal operation of the refrigeration unit, but also adjust the energy consumption and refrigeration capacity of the refrigeration system, so that the operating cost of the refrigeration system can be reduced to more economical state.
It adopts LCD touch screen programmable temperature controller and has the functions of automatic test operation and PID parameter self-tuning. The setting of the control parameters adopts the Chinese interface and the man-machine conversation mode. The automatic operation function of the refrigerator can be realized only by setting the temperature. The control system uses an intelligent control software system, which can automatically combine the working conditions of refrigeration, heating and other subsystems, so as to ensure high-precision control in the entire temperature range and achieve the purpose of energy saving and consumption reduction. The perfect detection device can automatically perform detailed fault display and alarm. For example, when the test box is abnormal, the controller will automatically display the fault status.
