ZT0020 Heat Transfer in a Tubular Heat Exchanger Teaching Equipment Heat Transfer Experiment Equipment
I. Product content
1 Product overview
1.1 Overview
The ZT0020 tube heat transfer test bench is a training and teaching device used in the laboratory to study the heat conduction between fluids in the pipeline flow process. The core part of the test bench is a sleeve. When flowing in the pipe, the hot water transfers part of the heat energy to the cold water when it is flowing. The flow direction of the water can be adjusted to study the heat transfer process of different arrangements such as forward and reverse flow. Temperature sensors are arranged in the middle of the inlet and outlet and the pipe wall to measure the water temperature and wall temperature. The hot water circuit includes a water tank with an electric heater and a water pump, and the flow of cold and hot water can be adjusted through a valve.
1.2 Features
The flow direction of the water in the ZT 0020 test bench loop cycle is adjustable, which is used to test different heat exchange processes such as downstream and countercurrent;
The circulating water temperature and circulating water flow rate in the loop can be smoothly adjusted;
Transient data during the change of the workbench is directly displayed on the display in digital form;
The data of various physical quantities in the changing process of the workbench can also be transmitted to the PC through the USB interface for further processing;
