Abstract

The invention discloses a high heat flow thermal environment simulation device, which comprises a support, a furnace body, a furnace cover, an insulation base, a heating body assembly, a test piece, a cooling medium inlet way, a cooling medium outlet way, a double-color integrated infrared temperature measurement meter, a vacuumizing device, an inflation opening, a pressure sensor, an explosion-proof opening and a power supply system. The high heat flow thermal environment simulation device of the embodiment adopts a medium frequency sensing mode for heating and can ensure heat to be added in time with high efficiency, and simultaneously, the structure of a cylinder ensures evenness of heating. The heating environment is protected by inert gas so as to prevent a graphite heating body from being oxidized by high temperature and enable the highest heating temperature to reach 2800 DEG C above so that the high heat flow thermal environment simulation device has the capacity of providing heat flow density of over 3MW/m2.

Description

technical field [0001] The invention belongs to the technical field of radiant heating devices, and relates to radiant heating devices, in particular to a high heat flow heat environment simulation device. Background technique [0002] In the process of engine development, in order to achieve effective cooling of high heat flow components, it is necessary to conduct experimental research and assessment on the cooling characteristics of the cooling structure. The heat flux conditions faced by the hot parts of the engine are more than 3MW / m 2 , Traditional heating methods such as quartz heating cannot achieve such a high heat flux. At the same time, in order to study the heat transfer law of the cooling process, it is hoped to obtain the heating heat flow conditions that simulate the actual situation. Therefore, how to design a heating method that can provide high heat flux and relatively stable heat flux has become a key problem that needs to be solved urgently. [0003] T...
