Application of Keno laser chiller in the field of laser
- Clicks:665 Release time:2009/7/3
With the rapid development of China's economy, the laser industry has also developed rapidly. Chillers (circulating water coolers) have been used extensively in the laser industry. At present, there are many manufacturers of circulating water coolers in China, mostly start-stop refrigeration circulating water coolers, which are very convenient to be modified from household air conditioners. However, during the stoppage of the compressor, only the water in the water tank takes away heat, so the temperature is controlled. The accuracy is poor, and there must be a very large water tank, which is bulky and consumes a lot of water. In addition, the heat exchange system generally adopts a coil type heat exchanger, that is, the heat exchanger is immersed in a water tank for heat exchange, and thus the heat exchange speed is slow. In addition, due to the frequent start of the compressor, it will cause electric pollution, impact on the power supply system and other equipment, and also shorten the service life of the compressor.
In contrast, foreign manufacturers generally adopt non-start-stop type, but because of the technical difficulty of the production of non-start-stop circulating water coolers, it is difficult to simply assemble or modify, so only foreign or foreign investment companies can produce them at present. Need a certain scale, the price is also higher than the start-stop type. The main manufacturers of this product are: US THERMO NESLAB , American LABTECH , American JULABO and so on. Among them, LABTECH has built factories in China, and the H series water circulation adopts advanced PID temperature control and Hot Gas Bypass technology, and combines high-efficiency plate heat exchangers, high-pressure rotary vane pumps and fluorine-free environmentally friendly refrigerants. The standard product has a cooling capacity of 350W to 9000W and a temperature control accuracy of ±0.1 °C . Therefore, the price and service of its products have certain advantages over other foreign companies.
Dongguan Kainuo Machinery has actively cooperated with the world industry ling pioneers. The laser chillers produced at present have absorbed excellent heat exchange systems, and the precision plate heat exchange system and precise temperature sensing components have won recognition from customers. Introduced new products suitable for the majority of Chinese consumers.
The development of the laser industry, laser show industry also led to the rapid rise in the country, while our laser show to the international design, the use of laser requirements for circulating water cooler also increased, need to have an international quality - Industrial continuous Ability to work, high temperature control accuracy and good operational stability, lower failure rate and more. LabTech has cooperated with the laser show industry to strengthen the functions and improve various alarm functions. The flow rate is too low, the alarm output is abnormal, the temperature is abnormal, the compressor is overheated, the water level is insufficient, and the sensor is fault protected. , Add RS232 interface; special design for laser industry requirements, use stainless steel water pump to ensure no copper ion interference in the whole pipeline. The following table shows the technical parameters of the circulating water cooler H100A .
In addition, circulating water coolers are widely used in other laser equipment industries, such as laser cutting machines, laser marking machines, laser engraving machines, laser welding machines, laser drilling machines, and so on. The selection of high-end circulating water coolers with more stable performance and more complete functions will be the development of the industry.
