Description

Technical Field

[0001] The utility model relates to the technical field of plateau engine cooling, in particular to a portable drilling rig engine secondary cooling device. Background Art

[0002] In summer, due to the high temperature, the rotary drilling rig is in a high temperature state for a long time, and the engine temperature rises too quickly. When the external temperature is too high, it often causes the engine to "boil" and cause the viscosity of the engine oil to decrease, the cylinder to pull, the tile to burn and other faults; because the temperature in the cylinder is high at this time, the piston, cylinder liner and other parts are in an expanded state. If the engine is turned off immediately, some soft metal will fall off after the engine is shut down and cooled, and even the piston, piston ring and cylinder liner will stick together. In the existing technical solution, a cooling water tank is set in the engine to cool the engine, and the antifreeze in the water tank can also prevent freezing under low temperature conditions. However, due to the low air pressure in high-altitude areas, the boiling point of water becomes lower. For every 1,000 meters increase in altitude, the boiling point decreases by about 3.3°C, which easily causes the engine coolant to boil, thereby causing the coolant to boil and the heat dissipation effect to decrease.
