1. Introduction

In an increasingly global market, products are subjected to a variety of climatic conditions. From arid deserts to humid tropical zones, the durability and performance of a product are often determined by its ability to withstand environmental stresses. This has made thermal shock chambers, such as the LISUN GDJS-015B Temperature Humidity Chamber, invaluable in testing and development. A thermal shock chamber allows for the simulation of rapid temperature changes and high humidity, which are essential for predicting how products react to extreme environmental changes.

The LISUN GDJS-015B provides precise control over temperature and humidity, allowing researchers and manufacturers to simulate diverse climates and study their effects on products. This paper will cover the principles behind thermal shock testing, applications, and the specific advantages offered by the GDJS-015B chamber.

2. Principle of Thermal Shock Testing

Thermal shock testing refers to the process of exposing a material or product to rapid changes in temperature. This simulates the effects of sudden environmental changes, such as moving a product from a cold storage area to a warm room, or exposure to direct sunlight after a cold night. This can lead to a range of physical stresses, such as expansion, contraction, and condensation, which can impact product integrity.

Thermal shock chambers are designed to alternate between hot and cold temperatures, sometimes within seconds. This helps to evaluate a product’s resistance to cracking, delamination, deformation, and other potential failures.

4. Applications of Thermal Shock Chambers

Thermal shock chambers are used across various industries, including electronics, automotive, aerospace, and consumer goods. The ability to simulate different climatic conditions allows manufacturers to test product reliability and compliance with international standards.

• Electronics: Electrical components, such as printed circuit boards (PCBs), are vulnerable to temperature changes, which may cause solder joints to crack or circuit traces to fail.
• Automotive: Automotive parts, from engine components to dashboards, must endure a wide range of environmental conditions. Thermal shock testing ensures these components will not fail when exposed to extreme cold or heat.
• Aerospace: Aircraft components must withstand rapid temperature changes at high altitudes. Thermal shock testing helps ensure the integrity of these components.
• Consumer Goods: Products such as outdoor electronics or wearables need to perform in various climates. Testing ensures longevity and functionality under fluctuating conditions.

5. Experimental Procedure: Testing with the LISUN GDJS-015B

A typical thermal shock test with the LISUN GDJS-015B may follow these steps:

• Sample Preparation: The product or material to be tested is placed in the chamber, ensuring it fits within the designated test parameters.
• Initial Conditions: The chamber is set to the initial test environment, which could be either extreme cold or heat, depending on the requirement.
• Temperature Cycle: The chamber alternates between hot and cold temperatures, with specific hold times at each temperature point.
• Humidity Variations: Humidity levels are adjusted to simulate environmental moisture, which could lead to condensation or corrosion in real-world conditions.
• Data Collection: Throughout the test, data is recorded, including temperature, humidity, and product responses like deformation, cracking, or other failures.

The testing data can then be used to analyze product performance and reliability.

6. Data and Results

The following table provides a sample of the data collected from testing an electronic component under varying temperature and humidity conditions using the LISUN GDJS-015B.

Test Cycle	Temperature (°C)	Humidity (%)	Test Duration (Hours)	Observed Results
1	-40	30	4	No visible damage
2	85	90	4	Slight expansion observed
3	-55	50	6	Minor cracking on outer casing
4	150	98	2	Internal component failure
5	-70	20	3	No significant changes

The data shows that higher temperature and humidity combinations lead to material degradation, especially during prolonged exposure.
