What are the factors affect the wind cooling effect of the cooler
Air cooleris one of the cooler, the application is more, is my company's main production equipment, has many years of production experience, our company produces the cooler is popular with many users.Maybe some users to the cooler, there are many don't understand it today and you talk about what are the factors influencing the wind cooling effect of the cooler.
First, the consistency of matrix and the coefficient of thermal conductivity
Liquid material, in a certain temperature range, the better the liquidity, the less the friction force in the liquid material, the better the effect of heat transfer, the greater the coefficient of thermal conductivity in;
Second, the metal materials thermal conductivity
Different metal thermal conductivity coefficient, metal stuff with good electrical conductivity, thermal conductivity or;
Third, metal surface finish
Matrix viscosity at room temperature in 450 pa. S, contact with the wall would produce a strong adhesive.When the metal surface is rough on the surface will adhere to a substrate layer, wall surface is rough, adhesive layer is thick, continuing cooling, then this thing adhesive layer adhesion effect is stronger, the thermal resistance is the adhesive layer and the metal wall thermal resistance, the sum of led to the decrease of the coefficient of heat transfer into the;
Four, heat transfer area S
The heat conduction formula shows that the area of the substrate in contact with the metal tube wall S is larger, the better the cooling effect;
Five, the cooling water temperature
The heat conduction formula shows that when the delta T is big, the heat exchange of the Q value.After the test, when the cooling water temperature below 40 degrees, as the cooling water temperature drop, the temperature of the substrate and the cooling water temperature difference, the greater the the temperature change, the greater the adhesion in the matrix of metal wall more thick, such as driving matrix of pressure is too low, on the wall of matrix don't exercise, the thermal resistance increase.Only when the water temperature in more than 40 degrees, the temperature change, the greater the cooling effect will be better;
The influencing factors of the wind cooling effect of the cooler and there are many, such as the cooling water column spacing, the oil film strength, etc., in order to get the good cooling effect, in addition to the associated with the performance of the cooler itself, also need to check from these aspects research.
