Electromagnetic induction heating gas heat exchange experimental device

Abstract

The invention discloses an electromagnetic induction heating gas heat exchange experimental device. The device comprises a gas injection pipe; a device main body, an experiment tube, a heat insulation layer and an induction coil are arranged in the device main body; one end of the experiment tube is communicated with the gas injection tube; the heat insulation layer is arranged outside the experiment tube in a sleeving manner; the induction coil is arranged outside the heat insulation layer in a sleeving manner; an exhaust pipe which is communicated with the other end of the experiment tube; and an induction heating power supply which is electrically connected with the induction coil. Non-contact induction heating is carried out on the experiment tube through the induction coil, the phenomenon that the experiment tube is powered on is avoided, therefore, personnel safety is ensured, and the device is more stable in operation, more uniform in wall surface heat flux density, better in air tightness and higher in experiment precision.

Description

technical field [0001] The invention relates to the technical field of energy and power, and more specifically relates to an electromagnetic induction heating gas heat exchange experimental device. Background technique [0002] Due to its low density and good compressibility, gas is often used in energy and power industries with special needs, such as gas turbines and equipment, air-cooled aero engines, rocket engines, helium-cooled nuclear fusion reactor cladding, high-temperature air-cooled reactors (helium, nitrogen , argon, carbon dioxide, helium-xenon mixed gas, etc.), hydrogen cooling nuclear thermal propulsion reactors and various gas heat exchangers, etc. The flow and heat transfer characteristics of gas in these devices affect the operating performance and safety of these devices, so relevant experiments are needed to study this issue. [0003] Due to the low density of the gas, the experimental device will leak due to reasons such as poor sealing and structural fa...

AI Technical Summary

Problems solved by technology

[0003] Due to the low density of the gas, the experimental device will leak due to poor sealing and structural failure during long-term operation, especially flammable and explosive gases such as hydrogen, which will lead to dangerous accidents

And the heating method in the prior art mainly adopts electric contact test tube to heat, so it is very easy to cause the test tube to be electrified or even leak, so there is a potential safety hazard
