Description

Cooling machine

Technical Field

The utility model relates to the technical field of circulating water systems, in particular to a cooler.

Background

The cooling machine is generally used for cooling liquid in a circulating water system, and three cooling modes adopted by the cooling machine at present are as follows:

and (3) air cooling and cooling: the fan is adopted to drive air to flow, so that the air and the liquid are subjected to heat exchange, the purpose of cooling is achieved, and the cooling efficiency is low in the mode, but the energy waste is small.

And (3) water cooling: the water pump is adopted to drive the cooling liquid to flow, so that the cooling liquid exchanges heat with the liquid in the circulating water system, the purpose of cooling is achieved, the cooling efficiency is relatively high, the energy waste is small, the tightness of the cooling liquid is required to be ensured, and the cost is high.

The refrigerator cools, through the cooperation of evaporimeter and condenser, takes away the heat in the liquid fast, reaches quick refrigerated purpose, and its cooling effect is best, but its extravagant energy that is relative is great, and the cost is also higher.

In summary, each of the three cooling modes has advantages and disadvantages, and in practical use, there is a cooler for combining two or three modes to achieve a better cooling effect, wherein the combination of air cooling and water cooling generally only has an effect of 1+1 being equal to 2, i.e. the two cooling modes only work independently to achieve respective cooling effects. If the liquid in the circulating water system is rapidly cooled by cooling liquid, and then the fan is arranged at the rear part for air cooling, the cooling effect is lower than that of completely using water cooling, but the cost is relatively reduced; the cooling effect is higher than that of the full use of air cooling, but the cost is relatively high.
