Universal combined cooling type modular radiant heater

Abstract

The invention provides a universal combined cooling type modular radiant heater. The heater is composed of a guide cooling rod [1], a lamp holder clamping base [2], quartz lamps [3], a reflecting plate [4], a main connecting screw [5], a wiring board [6], a water outlet pipe [7], a water inlet pipe [8], an air inlet pipe [9], an insulating lining wood plate [11], a base [12], a mounting base plate [13], a sliding rail and sliding block unit [14] and a frame rack [15]; and the guide cooling rod [1] is fixedly installed on the frame rack [15] through the main connecting screw [5], and the quartz lamp tubes [3] are fixedly installed on the guide cooling rod [1] through the lamp holder clamping base [2] to form a horizontally-placed dense plane lamp array. The quartz lamp tubes and the quartz lamp porcelain head are cooled, so that the heating limit capability of the quartz lamp tube can be effectively improved, the service life of the quartz lamp tube is prolonged, and the test reliability is improved. The heater can be adapted to thermal tests under different heating conditions, and the test cost is reduced.

Description

technical field [0001] The invention relates to the field of aerodynamic thermal simulation tests, in particular to a general-purpose combined cooling modular radiation heater. Background technique [0002] In the field of aerospace, there are many aerodynamic and thermal problems in aircraft such as bombs and arrows. It is necessary to conduct simulated heating tests on the typical structures of bombs and arrows to evaluate their thermal insulation performance. Quartz lamp heater is a heating element widely used in thermal tests at home and abroad. It applies a voltage across the quartz lamp array to increase the temperature of the filament and radiate energy outward. [0003] In recent years, the heating heat flux required in aerothermal simulation tests has become higher and higher, and the working environment of quartz lamps has become increasingly harsh. The rise of the temperature will cause the softening and damage of the lamp tube wall, so the cooling technology is...

AI Technical Summary

Problems solved by technology

[0004] In the past, flat-plate radiant heaters were mainly used for aerothermal simulation tests of test piece-level products. Most of the test pieces were standard test pieces, so the heaters were mostly designed in a fixed form. As a result, the heater could only be adapted to a quartz lamp of a specific length and could not Adjust the spacing of quartz lamp tubes
