Abstract

The invention relates to an intro-motor fluid and heat exchange coefficient testing device. Different cooler models are installed at a testing section of a backflow type wind tunnel, heating energy is rightly taken away by cooling water under different wind speed and water speed due to adjustment of the heating power of a heater and in and out water flow of a cylindrical container, and measured physical variables are collected when thermal stability is achieved. Research of the heat dissipation performance and wind resistance performance of testing coolers are achieved due to processing of numerical values of the measured physical variables. The intro-motor fluid and heat exchange coefficient testing device which really and reliably stimulates the cooler operation environment in a motor has the advantages of having functions of automatic control, automatic data collection, automatic data processing, real-time monitoring and the like, being advanced in testing mean and accurate in testing data, designing and selecting a most suitable cooler for the motor, providing accurate testing data, providing guarantee for safe and reliable operation of the motor and being applicable to performance tests of gas coolers.

Description

technical field [0001] The invention relates to a test device for fluid and heat exchange parameters in a motor. Background technique [0002] With the development of the motor industry, the capacity of a single machine has been continuously increased, and higher and newer requirements have been put forward for the cooling technology of the motor. The gas cooler is an important part of the heat exchange and cooling of the motor. The quality of the heat dissipation system of the gas cooler directly affects the overall cooling effect of the motor. Therefore, in the design of the motor, choose the one with high heat dissipation performance, lower wind resistance pressure, and economical and reasonable Gas coolers are very important. The structural forms of the gas cooler include coiled spring, coiled disc, needle punched, extruded disc and pierced disc, and the heat transfer materials include copper, navy copper, aluminum, stainless steel, titanium, etc. At present, there are...
