I want to build a cold storage. What's the difference between water cooling and air cooling?

1, different in nature: the water-cooled radiator has a water inlet and a water outlet, and there are many waterways inside the radiator, which can give full play to the advantages of water cooling and take away more heat. Air cooling is a cooling method, that is, air is used as the medium to cool the objects that need to be cooled.

2. Different characteristics: air cooling usually increases the surface area of the cooled object, or accelerates the rate of air flowing through the object in unit time. As the working elements such as cooling water tank and water pump are all arranged outside the chassis, water cooling not only reduces the space occupation in the chassis, but also obtains better cooling effect.

3. Different principles: The water-cooled (liquid-cooled) cooling system must have the following components: water cooling block, circulating liquid, water pump, pipeline, water tank or heat exchanger. Air cooling is the use of air as a medium to cool objects.

Extended data:

Precautions:

1、? Deionized water and distilled water can be used as cooling water, and the cooling water replacement cycle is within 30 days, and the filter element replacement cycle is within 90 days. Cooling water must be clean. If there are impurities in the water, they may be deposited in the water cooling plate, resulting in poor heat dissipation.

2. Because the laser and the output head have different requirements for water temperature, it is suggested to use a water cooler with double temperature and double control to provide refrigeration for the laser and the output head. Set the waterway temperature of laser refrigeration according to the provisions of the laser user manual, and set the waterway temperature of the output head as the highest temperature of the working environment of the day.

3. When the ambient temperature is lower than 0℃, it is recommended to use a water cooler with heating function, and the water cooler is always on. When the water cooler is not used, drain the cooling water. If the water cooler with heating function cannot be used due to conditions, special coolant can be used according to the local actual temperature.
