The difference between uv printer water cooling and air cooling
What is the difference between water-cooled and air-cooled UV printers? Is it water-cooled or air-cooled? In actual selection, how should you choose a suitable cooling system based on your own material requirements.
First, you need to understand what the two systems are.
Water cooling system refers to the use of cooling water to cool the temperature of LED lights. Its principle is to use water (or antifreeze) as a cooling medium to take away the heat of high temperature parts to ensure the normal working temperature of the parts. Water cooling system consists of water pump, radiator, fan, thermostat, water jacket and water pipe.
Air-cooling is to use a fan to blow air or suck air. Its principle is to use air as a cooling medium. High-speed air directly takes away the heat of high-temperature parts to reduce the temperature of the engine.
The difference between the two cooling methods:
1. The corresponding drying lamps are different; water cooling generally corresponds to led ultraviolet curing lamps, and air cooling corresponds to mercury lamps. In the early days of the industry, there were also LED-cooled air-cooled systems. Water cooling is performed by installing a liquid flow tube device on the LED lamp cover to cool down, and air-cooled fans are installed on the mercury lamp to take away the heat.
2. The cost is different. The air cooling only needs to install fans, power lines and other devices, and the required cost is low; water cooling needs to be equipped with special pumps, radiators, water pipes and other components.
What are the advantages and disadvantages of UV printer water cooling:
1. Eliminates the need for fans on air-cooled lamps and heat pipes, fins and other components inside the bulb.
2. There is no inclusion in the upper part of the lamp tube, which will not affect the heat dissipation effect, and at the same time, ensure that the scattering angle of the beam is expanded to 360 degrees, improving the curing efficiency.
3. Good cooling effect, uniform cooling, reliable work, not affected by the environment, and low noise.
Disadvantages: complicated structure, high cost, high failure rate and complicated maintenance. Because there are energy consuming devices such as water pumps and water tanks, the power loss is large.
What are the advantages and disadvantages of UV printer air cooling:
Advantages: few air-cooled parts, simple structure, light weight, low manufacturing cost, high power utilization rate, no leakage, freezing, scaling and other failures, convenient use and maintenance, good environmental adaptability, and short warm-up time after startup
The disadvantages are the uneven cooling surface, high heat load, affecting the stable use of the drying lamp, large fan power consumption and high noise during operation.
So in the actual selection process, how to choose two cooling methods?
Water cooling is recommended, and 90% of manufacturers in the industry have already used it. The air-cooled mercury lamp is an early technology in the industry, and the mercury lamp itself is relatively harmful. The leakage of internal mercury is very harmful to the technician and the surrounding environment. In addition, the life of the mercury lamp is too short, although the price is cheap, but frequent replacement, wasted labor and time costs are relatively high.
