Controlo da temperatura durante o ensaio de baterias de veículos de energia nova
With the continuous implementation of energy saving and emission reduction policies, new energy power batteries are also continuously encouraged to develop, and liquid cooling systems have become an inevitable trend for new energy vehicles. The original new energy vehicles can no longer solve the problem of battery heat dissipation by using air-cooled heat dissipation. The advantages of the liquid cooling system of Lneya's KRY high and low temperature coolant tester are fast cooling rate, goo...

From the perspective of the entire semiconductor industry, semiconductors can be divided into R & D, production, and application stages. At different stages, the role of testing is different. Control of test equipment, including test machines, probe stations, sorting machines, etc. Used in different processes and under different working conditions, integrated chip test instruments need to pay attention to some use knowledge when used. Temperature changes on the chip can significantly affe...

Vantagens da desgasificação e da desnaturação antes da destilação
Prior to distilling oil, you should follow a winterization and degassing procedure. The winterization will remove fats, waxes, and other inactive and unwanted compounds. Degassing will remove any solvents and other inactives with low boiling points to prevent foaming during distillation. These processes are imperative to successful distillation and could be considered more important than the actual distillation itself. Always use safety equipment and have proper ventilation when working with ...

Efeito do ciclo de temperatura de arrefecimento e aquecimento durante a emulsificação
Emulsification is the effect of a liquid in which even tiny droplets are evenly dispersed in another liquid that is incompatible with each other. Emulsification is a liquid-liquid interface phenomenon. Two immiscible liquids, such as oil and water, are divided into two layers in a container. Oil with a lower density is in the upper layer, and water with a higher density is in the lower layer. If an appropriate surfactant is added and the mixture is vigorously stirred, the oil is dispersed in ...

Sistema de simulação de arrefecimento para ensaio de desempenho extremo de baterias
With the development of technology, pure electric vehicles are becoming more and more common, but pure electric vehicles are difficult to get a better solution in terms of cruising range, charging speed, and pollution after battery waste. This makes scientific research workers and related companies in various countries The ideal goal of using energy is to turn to proton exchange membrane fuel cells, thus carrying out a lot of scientific research and real car experiments. In order to improve t...

Temperature control of integrated circuit/chip wafer quality and reliability test items
The most basic part of making a chip is design-tape-package-test. The chip cost structure is generally 20% of labor cost, 40% of tape, 35% of package, and 5% of test. The test is actually the most in all aspects of the chip. "Cheap" step, but the test is the final level of product quality. If there is no good test, the product PPM [Million Failure Rate] is too high, and the return or compensation is far from 5% of the cost. What tests do chips need to do?There are three main categories: chi...

What is VCSEL in the chip Burn-in Test? What effect does temperature have on it?
The full name of VCSEL is Vertical-cavity Surface-emitting Laser, the Chinese name is vertical cavity surface emitting laser. It is a kind of semiconductor laser. Semiconductor lasers are lasers manufactured using semiconductor manufacturing technology. Like all semiconductor-manufactured devices, semiconductor lasers have smaller size, lighter weight, lower power consumption, higher reliability, and longer lifespan than solid, gas, and liquid lasers. Features. Semiconductor lasers are divide...

Unidade de controlo da temperatura necessária para a extração de matérias-primas químicas da medicina chinesa-TCU
The production process of traditional Chinese medicine raw materials is relatively complicated: long process, many pipelines, and complicated operations; and most of the preparation raw materials are unstable, such as high environmental parameters such as temperature, humidity, and light, and related raw materials are mostly flammable and explosive. Unlike the preparation product process, the production process of traditional Chinese medicine raw materials is mostly a cross-fusion process of ...

Descrição do solvente e instalação do equipamento de arrefecimento da destilação
During the chemical reaction, most of the chemical reactions are carried out in solvents. Solvent is an important medium, which can make all kinds of molecules participating in the reaction evenly distributed, increase the chance of collision and contact between molecules, and accelerate the progress of the reaction. The solvent can conduct heat, through which it can provide heat to the reaction substance, and promote the progress of the reaction; through it, it can also transfer the heat rel...

A existência de destilação e controlo da temperatura durante a destilação - controlo dinâmico da temperatura Sundi
Distillation exists in industries such as biopharmaceutical and petrochemical industries. Laboratory distillation includes vacuum distillation, short-path distillation, thin-film distillation, steam distillation, batch distillation, azeotropic distillation, industrial distillation (multi-effect distillation), etc. Then, temperature control must be performed in the distillation treatment step. However, temperature control is only one of many process variables in pressure, flow rate and composi...
