Circulating water coolers, also known as chillers, are one of the essential components in laser processing equipment. Now, let's talk about the current state of circulating water cooler technology on laser processing equipment. At present, the domestic circulating water coolers are mostly start-stop refrigeration circulating water coolers, which are very convenient to be modified from household air conditioners. However, during the stop of the compressor, only the water in the water tank takes away heat, so the temperature control accuracy is poor. And there must be a very large water tank, so it 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, non-start-stop type is widely used in foreign countries. However, due to the technical difficulty of the production of non-start-stop circulating water coolers, it is difficult to simply assemble or modify. Therefore, only foreign or foreign investment companies can produce them at present. At a certain scale, the price is also higher than the start-stop type. The development of the laser industry has also led to the rapid rise of the laser show industry in China. At the same time, our laser show design has also gone international. The requirements for the circulating water cooler are also increased. The international quality is required. Ability to work, high temperature control accuracy and good operational stability, lower failure rate and more. Of course, circulating water coolers are widely used in other laser processing 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.

Orlistat is a long-acting and potent specific gastrointestinal lipase inhibitor. It is white or off-white powder at room temperature. It is insoluble in water, soluble in chloroform, and easily soluble in ethanol. It passes through the stomach and small intestine cavity. Intragastric lipase and pancreatic lipase active codon form a covalent bond to inactivate the enzyme. Fat in food cannot be broken down into free fatty acids and monoacylglycerols, so the fat cannot be absorbed and utilized, thereby reducing the body's caloric intake and controlling body weight. This medicine does not need to be absorbed through the body to exert its effects. At the usual dose, fat absorption can be suppressed by 30%. It is rarely absorbed after oral administration and can be metabolized and inactivated in the intestine. The metabolic site is on the wall of the gastrointestinal tract, and the elimination half-life is about 14 to 19 hours. About 97% of this product is excreted with feces, of which 83% is excreted in the original form.
Orlistat can be used clinically for obesity and hyperlipidemia. Under normal circumstances, 120mg can be taken orally once a day, three times a day, and taken within one hour after a meal. After taking the medicine for 2 weeks, the weight may start to decrease. It can be taken continuously for 6 to 12 months. If the dose is increased to more than 400 mg per day, its effect will no longer be enhanced.
