Description

technical field

[0001] The invention relates to an oil cooler in the field of mechanical technology, in particular to a compact oil cooler. Background technique

[0002] The oil cooler is widely used in mechanical gearboxes or vehicle engines. Its working principle is to circulate and cool the lubricating oil through the convective heat exchange between the coolant side and the oil side, and effectively control the temperature of the engine oil within a certain range. of normal operation. Since the heat transfer coefficient of the oil side of the oil cooler is smaller than that of the water side, that is, the control thermal resistance of the cooler is on the oil side, so the oil side often adopts a compact surface to enhance heat transfer. The power of automobile engines is getting higher and higher, and the trend of engine miniaturization requires that new oil coolers should not only have high-efficiency heat exchange power, low pump power consumption, but also have a com...
