Product Testing and Characteristics of Lijia Negative Temperature Control Humidity Test Chamber

With the birth of new equipment and new technology, the consumption of welding materials in my country has been declining year by year. The proportion of welding rods in the total output has dropped from 52.74 in 2009 to 37.59 in 2018. The main reason is "low cost and low quality". There is a product structure problem of overproduction of low-end products and insufficient high-end products, which can only be used in secondary projects. From the perspective of the development trend of welding technology, good welding quality, low cost, high production efficiency is a measure of the welding industry. For this reason, Lijia negative temperature-controlled humidity test chamber can provide safety solutions for welding technology for manufacturing and major projects.

Brief Analysis of Condensation Phenomenon Produced by Environmental Test Chamber

In the environmental experiments of new energy power batteries, components, board-level and unit-level modules, it is easy to cause physical phenomena such as condensation on products when the temperature rises rapidly. The generation of this condensation phenomenon is related to the product material, the size of the cavity, the rate of temperature rise and fall, the relative humidity, the air pressure in the box and the air velocity.

New energy battery auxiliary equipment: Lijia multi-channel high and low temperature liquid cooling tester

The multi-channel high and low temperature liquid cooling tester developed by Guangdong Lijia is a special tester for refrigerators. The liquid cooling technology takes away the heat generated by the battery and reduces the battery temperature through liquid convection heat exchange. The liquid medium has high heat transfer coefficient, large heat capacity, and fast cooling speed, which has a significant effect on reducing high temperature and improving the consistency of the battery pack temperature field. At the same time, the volume of the thermal management system is relatively small. The form of liquid cooling system is more flexible than that of water cooling system. The battery cells or modules may be immersed in the liquid, cooling channels may be provided between the battery modules, or a cooling plate may be used at the bottom of the battery.

What is the help of the reliability and rapid temperature change test box for product testing?

Environment Stress Screen (ESS) is a series of tests under environmental stress to find and eliminate defective parts, components and process defects in products and prevent early failure. It mainly applies reasonable environmental stress and electrical stress to products at all levels above components to accelerate potential defects into faults, and finds and eliminates faults through inspection, is a process means. The environmental stress includes the rapid temperature change test. The Lijia rapid temperature change test can judge the storage or working adaptability of the product under the condition of temperature change. The purpose of the identification test is to check whether the product meets the requirements of the relevant standards; the improvement test is mainly used to evaluate the durability and reliability of the product under the condition of temperature change.
