How to choose the water cooler of the laser cutting machine?
Updatetime: 2021-09-09 16:19View:
With the continuous application of laser cutting machines in various industries, the sales volume of laser cutting machines is also increasing year by year. Of course, the chiller has become an indispensable part of the laser cutting machine in the process of use, so everyone is buying industry when the water chiller is used, how should I distinguish whether to choose a water-cooled chiller or an air-cooled chiller? Here is a brief introduction to these two types of air coolers, hoping to better help you when you choose the chiller on the laser machine equipment.
 


What is a chiller? Water chiller is a kind of water cooling equipment. It can provide cooling equipment with constant temperature, constant flow and constant pressure. However, the principle of chiller is to inject a certain amount of water into the internal water tank of the machine, and the water is cooled by the cold water mechanism system, and then The water pump inside the machine injects low-temperature chilled water into the equipment that needs to be cooled. The chilled water takes away the heat inside the machine, and returns the high-temperature hot water to the water tank to cool down. In this way, the cyclic exchange and cooling achieves the effect of cooling the equipment. . The types of chillers can be divided into air-cooled chillers and water-cooled chillers according to different cooling forms of chillers.

The working principle of air-cooled chiller

Air-cooled chillers transfer heat to the air. Air-cooled chillers use aluminum fins for air flow and copper pipes for refrigerant flow. Air-cooled chillers are mainly used in small and medium-sized commercial and industrial spaces to humidify air or cool products. They are compact, efficient and easy to disassemble and install.
 
The external air can be directly used for mechanical circulation through the condenser coil to dissipate heat. Air-cooled chillers require external space because they require sufficient fresh air to operate. It is susceptible to environmental factors such as heat, ice and rain, which usually result in the need to replace parts. Any obstruction in the airflow will result in restricted airflow, which can lead to complications.

 

The working principle of water-cooled air cooler

The water-cooled chiller adopts water cooling to dissipate the heat of the unit. During operation, the gas phase changes continuously through the circulation of the refrigerant, and the phenomenon of heat absorption and heat release occurs, which promotes the alternating circulation of cold and heat, thereby taking away the heat in industrial production and achieving cooling.
 
There are many types of chillers, such as the above-mentioned water-cooled chillers, there can also be air-cooled chillers, screw chillers, explosion-proof chillers, integrated chillers, water-cooled box chillers, and so on. However, the basic composition is roughly the same, such as compressor, condenser, expansion valve, evaporator, electric control system, water pump, flow meter, high and low pressure meter, dryer, oil-water separator and so on.
 

The difference between water-cooled chillers and air-cooled chillers

In terms of technology, the energy efficiency ratio of water-cooled chillers is 300 to 500 kcal/h higher than that of air-cooled chillers; in terms of price, water-cooling is much lower than air-cooling; in terms of installation, water-cooling requires It can be used only when it is incorporated into the cooling tower, while the air-cooling is movable without other assistance. Although air-cooled units have significant advantages in saving water, simplifying systems, and saving installation space, the overall air-conditioning construction project includes civil construction costs, cooling water and chilled water system costs, electrical control and supporting management fees, and Compared with water-cooled chillers, air-cooled chillers have no advantages over operating costs.
 
   In fact, whether it is a water-cooled chiller or an air-cooled chiller, it has advantages and disadvantages. It only depends on which type of chiller is more suitable for your current situation. Only after the advantages and disadvantages of the unit can we better choose a suitable chiller for you.
