Description

Technical Field

[0001] The utility model belongs to the technical field of heating devices, in particular to a constant temperature heating device. Background Art

[0002] Constant temperature heating refers to the process of heating the object to be heated at a constant temperature. In this process, the system constantly monitors the temperature of the object and makes adjustments based on the monitoring results to maintain the stability of the heating temperature. Constant temperature heating systems usually consist of temperature monitoring equipment, heating equipment, and controllers.

[0003] Constant temperature heating is widely used in biotechnology, medical equipment, chemical laboratories and other fields. In biotechnology, for sample containers that require constant temperature heating, the system can control the temperature of the sample surface through a constant temperature to ensure the accuracy of the experiment. In the field of medical equipment, constant temperature heating can be used to treat certain abnormal symptoms on the body surface, such as muscle pain, ligament injuries, etc. In chemical laboratories, constant temperature heating technology can be used to study the reactions of certain compounds and to generate cells or other complex structures. The advantage of constant temperature heating is that it can ensure that the sample reacts continuously at a constant temperature, thereby avoiding experimental errors caused by temperature fluctuations. The disadvantage is that a more complex control system is required to ensure that the constant temperature can be accurately monitored and controlled. In some cases, constant temperature may also cause uneven reaction rates and affect experimental results. Summary of the invention
