The Importance of High and Low Temperature Termal Shock chamber in Product Development

The High and Low Temperature Termal Shock chamber, also known as the explosion-proof constant temperature and humidity test chamber, is a professional equipment used to test the performance of materials and products. The testing machine can maintain the temperature, humidity, and testing time values set by the user, and can achieve continuous and uninterrupted testing through program settings.

Mainly used to test the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials and products. It is used to assess the adaptability test of relevant product parts during storage, transportation and use in high and low temperature environments, and to evaluate the physical changes and material properties of products after the environmental test of thermal expansion.

High and low temperature impact testing is a commonly used testing method for evaluating the high and low temperature resistance of materials or products. Its main purpose is to determine the reliability, stability, and durability of the product at different temperatures, in order to confirm whether it can operate normally in specific temperature environments.

At the same time, high and low temperature impact testing can help product manufacturers and designers understand the weaknesses and defects of products, and provide basic data and direction for improving and optimizing products.The significance of high and low temperature impact testing is significant.

Firstly, the reliability and stability of a product are important factors for product quality and safety. Only after undergoing high and low temperature impact tests can the quality of the product be fully guaranteed and consumers can use it with peace of mind.

Secondly, high and low temperature impact tests can help enterprises reduce product failure rates, improve product quality, and enhance their reputation and competitiveness. In addition, high and low temperature impact testing is a method of testing the performance of simulated products in actual usage environments, which is very helpful for effectively evaluating the lifespan and reliability of products.

Technically speaking, the biggest advantage of high and low temperature impact testing is that it can evaluate the performance and reliability of products in a short period of time. These tests can be completed in a short period of time and provide an evaluation of the adaptability and functionality of the product at different temperatures.

Therefore, high and low temperature impact tests are widely used in fields such as electronics, aviation, automotive, medical equipment, and some products require extreme temperatures to operate normally.

In short, high and low temperature impact testing is one of the indispensable testing methods in product design and manufacturing. Through this method, manufacturers and designers can understand the performance and reliability of products to meet consumers’ requirements for product quality and safety. At the same time, it can also help enterprises improve product quality, competitiveness, and performance.

There are two types of high and low temperature impact testing methods: vapor method and liquid method.
There are two methods for using the vapor method. One is manual transformation, which involves changing the product between the high-temperature test chamber and the low-temperature chamber; Another type is an impact test chamber, which converts the temperature based on the power switch, cold and hot chamber air supply mode door, or other similar methods. The upper and lower temperature limits are the storage endpoint temperature values for new products.

The liquid method is obtained in the electric basket type, where the product is placed in the electric basket and infiltrated into a liquid at different temperatures according to demand. Suitable for glass metal hydraulic seals and similar products.

The importance of high and low temperature impact test chambers for product.
1. The impact of different temperature ranges is cut off by the multi-stage evaporator structure, and the evaporation area is matched with the refrigeration expansion valve. The refrigeration system output is used to reasonably reduce the output of the heater neutralization, achieving constant energy conservation; There is also an independent ventilation valve that acts to introduce ambient air during exhaust (room temperature recovery).

2. The air inlet sucks in external air when exposed to ambient temperature.
3. The exhaust port has a scheduled function of discharging hot air from the mechanical room and test area.
4. Set the start time of the test in advance, and the test box will automatically start and be ready to start the test.
5. Exposure time reduction function.
6. The function of switching to the next exposure after the downwind temperature in the experimental area reaches the exposure temperature.
7. Pre processing/post processing function.
8. Before or after the cycle test, the sample is exposed to a high-temperature environment (heat treatment) for a certain period of time.
9. Drying operation function.
10. Run the test piece for a certain period of time.

From the perspective of LED product quality, whether it is indoor or outdoor, the environmental climate of LED depends to a certain extent on the LED utilization rate. The high and low temperature impact test chamber environmental testing equipment can simulate the rapidly changing climate of high and low temperatures in the natural environment. The LED experimental product has been tested under natural environmental simulation, which is undoubtedly an important means to improve the product.

Why should LED lighting be tested using a high and low temperature impact test chamber?
1. The plastic shell of LED lamps is prone to embrittlement and damage under high and low temperature environmental impact;
2. LED tubes burn out when the temperature changes sharply;
3. LED circuit board chips are prone to short circuits in high and low temperature impact environments.
During the high and low temperature impact test process of qualified LED, after the high and high pressure test, the surface of the lamp cannot peel off paint, discolor, crack, material deformation, and other abnormal phenomena; After the impact test, there is no electrical leakage or abnormal gas phenomenon in the lamp.

In the natural environment, temperature and humidity are two inseparable natural factors. Due to different geographical locations, the temperature and humidity effects generated in different regions also vary. The high and low temperature impact test chamber is used to confirm the adaptability of products to storage and transportation under temperature, humidity, climate, and environmental conditions.

High and Low Temperature Thermal Shock Chamber can be used in the temperature shock test and fast-changing temperature test in a wide range such as aviation, air space, electronic components and material research.

HLST-500D has two separate chambers: high temperature chamber and low temperature chamber.
HLST-500T has three separate chambers: high temperature chamber, low temperature chamber and test chamber.
