Haishun Ship L16/24 Cooling Water Jacket

How to fill the cooling water jacket at high temperature

Generally, the cooling water is turned on before the temperature rises, and it has been turned on during the experiment (that is, the cooling water jacket is opened first and closed last) in order to prevent the high temperature from damaging the chamber. The water in the cooling water jacket flows in from the bottom and flows out from the top, which can better cool down the temperature.

The cooling of circulating water is the result of the three processes of evaporative heat dissipation, contact heat dissipation and radiation heat dissipation through the contact between water and air.

1. Evaporation heat dissipation: Water forms large and small droplets or extremely thin water films in the cooling equipment, expands its contact area with the air and prolongs the contact time to strengthen the evaporation of water, so that the water vapor will take away the necessary for vaporization from the water Heat thus cooling the water;

2. Contact heat dissipation: water is in contact with lower temperature air. Due to the temperature difference, the heat in the hot water is transferred to the air, and the water temperature is reduced;

3. Radiation heat dissipation: the phenomenon that heat energy is transmitted in the form of electromagnetic waves without the effect of heat transfer medium.
