Thermal Analysis of an Instrumentation Container for a Multi-Frame Recording System in a Linear Induction Accelerator of Electrons
Abstract
Both temperature and air-velocity fields inside the instrumentation container have been calculated and results of these computational studies have been presented.
The aim of this work is to determine the number of OverFrost 40 thermoelectric air conditioners and Schroff CR 027 air heaters needed to maintain the optimal air temperatures inside the container when the multi-frame recording system in the linear induction accelerator of electrons operates under the conditions of negative and positive ambient temperatures.
Calculations have been carried out in several stages in the 3D finite element model, in the gas-dynamic module of the engineering program that implements the finite element method. The temperature and air-velocity fields inside the container for one air conditioner and one heater, both located at the rear wall inside the instrumentation container have been determined in the first stage. Calculations have been performed for operational conditions of positive and negative ambient temperatures. The number of conditioners needed to ensure the sufficient cooling of air inside the container down to the optimal temperature in the positive temperature operational environment has been determined in the second stage. Results of settlement studies have shown that six conditioners and one heater are enough to maintain an air temperature of (20 ± 5) °С in the office accommodation volume at an environment temperature of – 5 °С. At the operation with the maximum capacity, a temperature of (20 ± 5)°С will be reached in about 5 min. At the block operation, a temperature of (20 ± 5)°С is supported by means of six conditioners during 120 min.
