ZM9302 Shell And Tube Heat Exchanger Thermal Lab Equipment Teaching Equipment Didactic EquipmentI.Product Overview
1.1 Overview
Shell and tube heat exchangers are widely used. The main advantages of this design are the large heat transfer surface and the compact design. Shell and tube heat exchangers are used in the chemical and pharmaceutical industries, refineries and process engineering plants.
A shell and tube heat exchanger consists of seven tubes surrounded by a transparent shell. Hot water flows through the tube spaces and cold water flows through the spaces in the shell. Part of the thermal energy of the hot water is transferred to the cold water.
1.2 Features
The tube-type heat transfer test bench is a practical training and teaching device used in the laboratory to study the heat conduction between fluids in the process of pipeline flow. The core part of the test bench is a casing, hot water flows in the inner tube, and cold water flows in the outer tube. When flowing, the hot water transfers part of the heat energy to the cold water.
The flow direction of the water can be adjusted to study the heat transfer process in different arrangements such as forward flow and reverse flow, and temperature sensors are arranged at the inlet and outlet pipes to measure the water temperature.
