Technical Field
The invention relates to a radiator, in particular to a box type air-cooled finned tube radiator for oil used for large-scale equipment.
Background
In large-scale operating equipment, heat is generated due to friction between components and when a heat source needs to be contacted, so that the temperature of lubricating oil, hydraulic oil and other oil used for blending is increased, the components of the equipment are damaged when the temperature exceeds the limit of the equipment, and the oil needs to be radiated for preventing the components from being damaged.
At present, the heat dissipation mode of large-scale mechanical equipment with larger heat productivity, such as a gear box, mainly comprises air cooling, water cooling or air cooling oil station cooling.
The air-cooled radiator is a heat-radiating system formed from copper or stainless steel sheet fin plate combination. The heat generated by the heat exchange of the fins on the fin plate is taken away by blowing air through the fan, so that the purpose of heat dissipation is achieved. However, the air-cooled radiator has a disadvantage that the gaps among the fins are small to increase the unit radiating area, particularly under the working condition with dust, the gaps among the finned tubes can be quickly blocked, and the gaps among the fins are small and are not easy to clean, so that the radiating efficiency is gradually reduced, and the radiating function is completely lost.
The water cooling radiator needs to continuously supply cooling water for heat dissipation. It has the problems that: the cooling water can easily cause the scaling of the inner wall of a water passage of the radiator in the working process and is not easy to clean; in addition, the cooling effect is gradually reduced along with the gradual increase of the scaling thickness until the scaling is scrapped. Moreover, if the cooling water contains corrosive ions, the corrosion-prone radiator is communicated with the inner wall of the water, so that oil and water are mixed, and the host machine is damaged.
In addition, as the oil station uses an oil pump to supply oil, once the oil temperature is lower than 5 ℃, the oil pump is difficult to start due to high viscosity of lubricating oil, so that the oil pump cannot supply oil.
