Do you know Two zone thermal shock chamber?

Two zone thermal shock chamber is also called a cold thermal shock machine, suitable for solar photovoltaic modules, batteries, automotive components, LED photoelectric, semiconductors, aviation, automotive, home appliances, scientific research, and other fields of testing equipment, for the safety performance of electronic components to provide reliability testing, product environmental endurance test, etc., so after the equipment test, can improve the reliability of products and product quality control. Two zone thermal shock chamber is mainly divided into two zone thermal shock chamber and three zone thermal shock chamber. Test samples are placed in the basket and lifted quickly to the working area for testing. So what is the two zone thermal shock chamber?

Here is the content list:

• Function Introduction

• Standardizing test requirements

• Operating instructions.

Function Introduction

Two zone thermal shock chamber is used to test the ability of composite materials and material structures to withstand the continuous harsh environment of high and low temperatures within a short period of time, i.e. to test the chemical changes or physical damage caused by thermal expansion and contraction within a short period of time. There are dozens of factors that have a significant impact on the use and life of the two zone thermal shock chamber. Engineers involved in the study of environmental conditions in engineered products have organized the environmental conditions that exist in nature and those induced by human activity into a set of test standards and specifications that are used to guide the environmental and reliability testing of products.

Standardizing test requirements

In order to standardize the tolerance of environmental test conditions in the test equipment, the cold and thermal shock chamber ensures the control accuracy of environmental parameters. Two zone thermal shock chamber in the high and low-temperature chamber switching transfer, the use of basket type control sample displacement, short conversion time in line with national regulations, short temperature recovery time, and fast temperature change. The overall structure of the equipment is compact, small in size and uses two chambers to enhance the temperature uniformity of the working area of the chamber. The refrigeration system and compressor adopt a modular refrigeration system with high efficiency and easy installation and maintenance. A compound refrigeration system usually consists of two to three independent vapor compression refrigeration cycles with different working temperature zones, taking the two-stage compound refrigeration cycle as an example, it consists of two parts, the high-temperature stage, and the low-temperature stage, forming two single-stage compression refrigeration systems working in a compound cycle.

Operating instructions

Before use, the operation of checking the power supply must have a good earth wire. Before testing, test items are not allowed to be flammable or explosive, or volatile, the purpose of this is to ensure the safety of the test environment. Do not alter the internal parts of the two zone thermal shock chamber as this may result in equipment failure and affect the service life of the equipment. Special attention should be paid to the fact that the two zone thermal shock chamber needs to be cleaned both inside and outside the chamber before and after the test, and regular maintenance is required when necessary. In the maintenance of the two zone thermal shock chamber, it is important to cut off the power supply to prevent personal accidents.
