Oil cooler formed by staggered dotting oil cooler pipes

Abstract

The invention discloses an oil cooler formed by staggered dotting oil cooler pipes. The oil cooler comprises a body, and the body comprises a core, an oil inlet chamber and an oil outlet chamber. The core comprises heat dissipation belts and the oil cooler pipes, the heat dissipation belts and the oil cooler pipes are arranged alternately, main pieces are welded to the two ends of the core, and oil passing holes are formed in the positions, corresponding to the oil cooler pipes, of the main pieces. The oil inlet chamber and the oil outlet chamber are welded to the main pieces of the core correspondingly, a groove is formed in a pipe body of each oil cooler pipe, and protection plates are welded to the two heat dissipation belts on the outer layer correspondingly. The oil cooler is small in weight, high in strength, capable of bearing large working pressure, high in assembling speed, convenient and fast to install, high in sealing performance and small in flow resistance and wind resistance. The oil cooler pipe is high in overall strength and good in stress dispersion, deformation, leakage and the like are not likely to occur in the using process, and the heat exchange efficiency, the sealing quality and the stability of the oil cooler are guaranteed. The oil cooler and the accessories used by the oil cooler have wide popularization and application value, and the market competitiveness of enterprises is improved.

Description

technical field [0001] The invention relates to the technical field of automobile radiator components, in particular to an oil cooler made of misplaced dotted oil cooler tubes. Background technique [0002] When the car is running, the temperature of the lubricating oil contained in the gearbox will continue to rise due to the transmission of power. If the temperature of the lubricating oil is too high, it may cause the lubricating oil to boil and lose its lubricating effect, thus making the gears easy to wear. How to ensure The lubricating oil temperature in the gearbox will not be too high, which becomes a very important issue. In the existing structural configuration of automobiles, oil cooler tubes are provided to cool lubricating oil and ensure that the oil temperature is within the normal working range. [0003] The automobile oil cooler in the prior art includes an oil cooler tube body, the oil cooler tube body has inner and outer double-layer tube walls, the tube en...

AI Technical Summary

Problems solved by technology

However, the cooling area of ​​the above-mentioned pipe body is limited, and a better lubricating oil cooling effect cannot be achieved.

[0004] Therefore, the original water-cooled structure has gradually developed and transitioned to the air-cooled stacked oil cooler, but the air-cooled stacked structure has more parts and solder joints, the process is difficult, and the failure rate is high. Cost and The weight of a single piece is relatively high

At the same time, there are many parts, difficult process assembly, and large flow resistance and wind resistance, which is not conducive to the market's requirements for automobile energy saving

When assembling the oil cooler tube body into an oil cooler, due to the unreasonable structural design, the welding strength is insufficient, so that the working pressure that the oil cooling tube body can withstand during work is small, and the pressure intensity at the inlet and outlet ends of the oil cooling tube body is also low. Weak, can not meet the requirements of use
