Abstract

The invention provides a combined heat radiation oil pipe composed of connected heat radiating oil pipe units. Two ends of a pipe body are provided with an oil inlet and an oil outlet respectively; the pipe units are in hollow cylindrical structures and comprise pipe layers and heat radiating layers from interior to exterior; cylindrical heat radiation projections are distributed on the outer surfaces of the pipe layers evenly; the inner sides of the heat radiating layers are provided with cylindrical heat radiating grooves, the outer sides are provided with Y-shaped radiating sheets evenly, and the outer side of each oil pipe unit comprises an inserting connection sheet; the heat radiating grooves match with the heat radiation projections; the tail ends of the inserting connection sheets are provided with inserting ends and connecting ends, and the inserting ends match with the connecting ends. The combined heat radiation oil pipe is simple in structure, convenient to install, large in heat radiating area and high in heat radiating efficiency and stability.

Description

technical field

[0001] The invention belongs to the field of auto parts, and in particular relates to a combined heat dissipation oil pipe. Background technique

[0002] At present, in the hydraulic power steering system of automobiles, ordinary straight and spiral steel pipes, rubber hoses, etc. are used as the connection methods of hydraulic pipelines. This structure has obvious defects in the case of frequent steering operations of the car: slow heat dissipation of the oil circuit of the power steering system , the hydraulic oil temperature rises sharply. When the oil temperature is higher than 130°C, the torque of the steering wheel of the car increases, and the system loses the power steering function. At the same time, the steering oil pump continuously bears a huge load, causing the oil temperature to rise; due to the small heat dissipation area of ​​the oil circuit, the heat dissipation effect is poor, when the steering oil pump and the high and low pressure oil ...
