Description

Technical Field

[0001] This utility model belongs to the technical field of experimental equipment for liquid heating and processing, and specifically relates to an experimental device for heating liquids. Background Technology

[0002] Heating liquids in ovens or drying chambers is primarily used for isothermal experiments or to accelerate chemical reactions, rather than for observing violent phase transitions such as boiling. It promotes chemical reactions in liquids at specific, stable temperatures. It allows for the determination of the total solids content of a solution by evaporating moisture through heating. It is also used for aging, curing, or stability testing of certain liquid samples (such as heat treatment of paints and coatings). In some cases, heating wires heat the air inside the chamber, and temperature sensors (such as thermocouples) and a control system maintain the chamber temperature at a set constant value (isothermal control).

[0003] Existing heating devices suffer from slow heating, low heating efficiency, and a single heating method resulting in uneven heating. Using multiple heating methods simultaneously in actual production can accelerate the heating rate and improve efficiency. Therefore, it is necessary to develop an experimental device capable of using multiple heating methods simultaneously to address the problems of existing heating devices, such as a single heating method, slow heating of the heat transfer oil, uneven heating, and low heating efficiency.
