Embodiment Construction

[0023] The specific implementation of the EMU oil pipeline cooling unit of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] See attached figure 2 , EMU oil pipe 7 road cooling unit includes oil pipe 5, radiator 2 and fan unit 3, oil pipe 5 is cooled by radiator 2 and fan unit 3, oil pipe 5 includes oil pipe 7 and pipe fitting 6, pipe fitting 6 is connected to oil pipe 7 Multiple positions are connected by setting expansion joints 8 at multiple connections between the pipe fitting 6 and the oil pipe 7 .

[0025] The expansion joint 8 is made of metal material, and a bellows expansion joint can be selected. For the different conditions of the installation location, various accessories such as pipe joints can be provided for connection, and the structure of the expansion joint 8 is a conventional or special-shaped structure, which does not affect the technical solution of the present invention.

[0026] The EMU oil...

Abstract

The invention relates to the technical fields of pipeline design and installation, and discloses a motor train unit oil pipeline cooling unit. The motor train unit oil pipeline cooling unit comprisesan oil pipeline, a radiator and a fan set, wherein the oil pipeline is cooled through heat dissipation of the radiator and the fan set, the oil pipeline comprises an oil pipe and pipe fittings, the pipe fittings are connected to multiple positions of the oil pipe, and multiple joints of the pipe fittings and the oil pipe are connected by setting expansion joints. The oil pipeline fitting connection of the cooling unit is replaced by the expansion joints, so that the mounting difficulty is reduced, and quick mass production is facilitated.

Description

technical field [0001] The invention relates to the technical field of pipeline design and installation, in particular to an oil pipeline cooling unit of an EMU. Background technique [0002] The cooling unit of the 250km standard EMU dissipates heat and cools the oil pipeline system. The cooling unit of the oil pipeline is located at the bottom of the car body, and the oil pipeline is installed in the frame of the cooling unit. Most of the oil pipelines are directly connected by hard pipes. Since the cooling unit has to withstand high heat and cold shocks, vibration during vehicle body operation, etc., the working conditions are quite harsh, and the requirements for oil pipelines are also high. [0003] See attached figure 1 The radiator 2, fan unit 3, filter 4 and other components are installed on the frame 1 of the cooling unit, the oil pipeline 5 is located under the frame 1, and the pipe fittings 6 on the oil pipeline 5 pass directly through the hard tube type oil pipe...
