Abstract

The invention discloses an experimental device for determination of periodic heat transfer coefficients, and the device can be used for determining heat transfer coefficients of different heat transfer cycles. The device comprises: a rotating steel bucket system, a gas water system, a heating system, a nozzle adjustment apparatus, and a temperature acquisition and processing system. The experimental device can adjust the steel bucket rotating speed to change the cooling surface movement speed so as to realize different heat transfer cycles. Different cooling ways can be achieved by changing different nozzles, and the cooling intensity can be changed by adjusting the air pressure and water pressure. The nozzle adjustment apparatus can change the spray angle and spray height of a nozzle. The device also can simulate a periodic cooling heat dissipation process with an internal heat source.

Description

technical field [0001] The invention relates to the technical field of measuring heat transfer coefficients of different periodic heat transfers, in particular to an experimental device for measuring periodic heat transfer coefficients. Background technique [0002] In the industrial cooling process, the heat transfer coefficient determines the cooling intensity. It is important to determine the relationship between different cooling water volumes, different nozzle spray heights, different spray angles and heat transfer coefficients for adjusting the cooling intensity. It plays a decisive role in formulating a reasonable cooling system and improving product quality. [0003] Periodic heat exchange exists in the production process of intermittent cooling in industrial production, that is, let the cooled workpiece pass through the arranged cooling nozzles once, and the workpiece is in a cooled state when it passes through the nozzle, and passes to the next nozzle when it leave...
