Abstract

An experimental device for testing the heat exchange amount of a cooler core comprises an air inlet channel and an air outlet channel, and the air inlet channel is connected with a constant-temperature gas input device through a ventilation pipe; the air outlet channel is connected with the air inlet channel through a cooler core body mounting frame, and the air inlet channel and the air outlet channel are connected to the two ends of the cooler core body mounting frame respectively; a guide slot is formed in the side surface of the cooler core body mounting frame; air temperature measuring devices are arranged at an air inlet of the air inlet channel and an air outlet of the air outlet channel; a cooling water input device is arranged beside the cooler core body mounting frame, and a water inlet pipeline and a water outlet pipeline of the cooling water input device are connected with a water temperature measuring device. According to the experimental device for testing the heat exchange amount of the cooler core body, the heat exchange amount of the cooler core body can be tested, and the experimental device has the advantages of being easy to assemble, high in detection efficiency and low in manufacturing cost; meanwhile, the invention further provides an experimental method for testing the heat exchange amount of the cooler core.

Description

technical field [0001] The invention relates to a cooler detection technology, in particular to an experimental device and an experimental method for testing the heat transfer heat of a cooler core. Background technique [0002] With the rapid development of my country's national economy, the demand for electricity is also increasing. With the continuous increase of power generation of generator sets, the calorific value also increases. The cooler is the core component of the transformer cooling system. The heat transfer is a key indicator to measure its performance. The cooler core needs to know the heat transfer to ensure the performance of the product. Therefore, the heat transfer of the cooler core is required. Quantities are tested to provide data support and basis for the design of coolers. In the existing technology, there is no corresponding experimental device for testing the heat transfer capacity of the cooler core, and the heat transfer performance of the produc...
