Cooling methods for the water well drilling rig depend on type, environment and needs. Options include air, water, oil and hybrid cooling.
-
Air cooling:
Uses fans;
simple,
low-maintenance,
no water needed.
Fits small rigs or dry areas.
Portable rig engines rely on it—fails in 35℃ heat after 2
hours.
-
Water cooling: Uses water/antifreeze; 3-5x more efficient than air. Suits large rigs. Truck-mounted rigs stay stable at 40℃, but need regular refills.
-
Oil cooling: For hydraulics; uses radiators for heat exchange. Compact, precise. A deep-well rig’s system starts fans at 45℃, saving energy.
Hybrid systems (
e.g.,
water +
air)
work for high-heat rigs.
One 300m rig stayed cool for 8
hours,
saving 15%
energy.
Choose based on environment and cost.
