Embodiment 2

[0037]The invention provides a comparison test method for the cooling effect of cooling pipes made of different materials for motor air coolers, which includes the following steps: the test method for analyzing the cooling performance of steel pipes, aluminum pipes and copper pipes at different wind speeds is to start three groups of heating modules to perform the test on steel pipes, aluminum pipes, and copper pipes. Heat the aluminum tube and copper tube to 35°C, set the ambient temperature of the experimental box at normal temperature, adjust the working wind speed of the fan through the frequency converter, and test the three-dimensional test at the wind speed of 4m / s, 8m / s, and 12m / s respectively. The cooling performance of the cooling pipes in the experimental materials was compared in groups, and the temperature data of the air outlets were collected by the temperature collector, and the statistical data were analyzed to reflect the differences in the actual heat dissipat...

Embodiment 3

[0039] The invention provides a comparative test method for the cooling effect of cooling pipes made of different materials for motor air coolers, including the following steps: the test method for analyzing the cooling performance of steel pipes, aluminum pipes and copper pipes at different heat conduction temperatures is as follows: start three groups The first combination of heating modules and the second group of heating modules heat steel pipes, aluminum pipes and copper pipes to 30 degrees, and the third group of heating modules heat steel pipes, aluminum pipes and copper pipes to 45 degrees to keep the ambient temperature at a constant temperature. The cooling performance of the cooling pipes in the three groups of comparative experimental materials was tested at a wind speed of 8m / s, and the temperature data of the air outlet was collected through the temperature acquisition instrument. By comparing the second group of comparative experimental materials with the first g...

Abstract

The invention discloses a contrast test method for cooling effects of cooling pipes made of different materials of a motor air cooler, and particularly relates to the field of mechanical design, and the contrast test method comprises the following operation steps: S1, selecting experimental apparatuses; S2, selecting experimental equipment; S3, installing each group of contrast experiment materials in the experiment box in a penetrating manner, wherein three steel pipes, three aluminum pipes and three copper pipes are longitudinally distributed in a same laboratory at intervals; and S4, nine heating modules are installed on the steel pipes, the aluminum pipes and the copper pipes respectively and used for heating the steel pipes, the aluminum pipes and the copper pipes, and the initial temperature is controlled. According to the invention, different motor heating performances are manufactured by using the heating modules, different heating working conditions of cooling pipes are truly simulated, the environment temperature in a use state can be simulated through the experiment box, and the experiment simulation comprises a plurality of heating working conditions, environment temperature, cooling air speed and cooling performances of cooling pipes with different lengths and different thicknesses. The comparison mode is comprehensive, so that the experimental data is more persuasive.

Description

technical field [0001] The invention relates to the technical field of mechanical design, and more specifically, the invention relates to a comparative test method for cooling effects of cooling pipes made of different materials for motor air coolers. Background technique [0002] It is to use the power to drive the impeller to rotate, and the generated eddy current will continuously inhale the air, and the cold air will transfer heat after contacting the hot pipe, cooling the hot material in the pipe. The air cooler uses the principle of the vortex tube, mainly using a compressed air source of 5.5-8 bar; the compressed air enters the air cooler, which can generate a cold air flow at one end (the temperature can drop -40°C), and a hot air flow at the other end (up to The temperature can reach 120°C), the cooling tubes of the air cooler can be made of different materials, mainly steel pipes and aluminum tubes, and few of them use copper tubes. The cooling tubes of different m...
