Ice water heat exchange coefficient experimental apparatus and measurement method

The invention provides an ice water heat exchange coefficient experimental apparatus which comprises a water tank 1, a water pump 3, a gate valve 4, a thermoregulator 5, a current meter 6, an ice thickness change measuring instrument 7 and a temperature recorder 8, wherein the water pump 3, the gate valve 4 and the thermoregulator 5 are sequentially connected through a pipeline 2 and form a loop; measurement probes of the current meter 6 and the temperature recorder 8 are positioned in the water tank 1; a measurement probe of the ice thickness change measuring instrument 7 is positioned in an ice layer 19 and water in the water tank. The invention also provides a method for measuring an ice water heat exchange coefficient by utilizing the device. The device well simulates reservoir icing and low-flow speed water flow conditions, acquires an ice water heat exchange coefficient of a corresponding reservoir and provides a design basis for water conservancy projects, also avoids the difficulty of developing reservoir ice water heat exchange coefficient prototype measurement in a rushing frigid zone reservoir area and provides great convenience and implementation possibility for research.
