Thermal design method for model selection and temperature field distribution of channel heater

Abstract

The invention provides a thermal design method for model selection and temperature field distribution of a channel heater, and the method comprises the steps: effectively simulating a conventional channel heater to carry out simulation calculation and analysis according to simulation software through building a three-dimensional model of the heater and the surrounding environment of the heater, and obtaining a simulation result; judging a simulation result by standard conditions of the channel heater, so that the optimization rate of the channel heater is greatly improved, the reasonable design of the structure of the heater is facilitated, and the problem that the channel heater is easy to damage is avoided; anyalzing the influence of the current magnitude and the water flow magnitude on the temperature field distribution of the heater so that the influence of the current magnitude and the water flow magnitude of the heater on the temperature of the heater is effectively detected, and the service life of the channel heater is prolonged.

Description

technical field [0001] The invention relates to the field of substrate glass manufacturing, in particular to a thermal design method for channel heater type selection and temperature field distribution. Background technique [0002] The pool furnace melts a certain proportion of batch materials, and the melted glass must go through a series of processes such as heating, clarification, and cooling in the channel before entering the next process. This stage is particularly important, and directly determines whether the glass can be formed or not. In order to achieve a series of treatments at the above channels, it is necessary to install heaters in each section of the channel to control the temperature of each section. Channel heaters are extremely important in the substrate glass manufacturing process. [0003] In actual use, the junction of the inner and outer plates of the channel heater is often damaged due to excessive temperature or uneven temperature, which affects its...

Problems solved by technology

[0004] Aiming at the problem in the prior art that the junction of the inner and outer disks of the channel heater often has poor heating effect due to excessive temperature or unevenness, causing damage to the channel heater itself, the present invention provides a method for channel heater selection and temperature control. The thermal design method of field distribution establishes a three-dimensional model of the channel heater and its surrounding environment, analyzes the internal structure and layout of the heater through simulation software, and finally obtains a channel heater with good heating effect and uniform temperature distribution
