Problems solved by technology

When using thin film heating, the difference in properties between the thin film and the heat sink material at high temperature will lead to huge thermal stress. When the resistance wire is heated, the heat flux density distribution will be uneven. The heating surface of the heating block and the heat sink surface have a large contact heat. resistance, so the high heat flux heating surface cannot meet the simulation requirements
[0003] The current simulation methods for heating surfaces with high heat flux have disadvantages such as low heat flux, large thermal resistance between the heating block and the heat exchange surface, inaccurate calculation of heat flux, or too slow heating response.

Abstract

The invention discloses a lens type simulation device of a high heating flux heating surface. The lens type simulation device structurally comprises a fixing component, a parallel light generator, a convex lens, a cooler and a visor, wherein the parallel light generator is installed on the fixing component and used for emitting parallel light which has low energy flux density; the convex lens and the cooler are sequentially arranged in the emitting direction of the parallel light, and the convex lens enables the parallel light with low energy flux density to form the high heating flux heating surface on the surface of the cooler. The high heating flux heating surface obtained by the simulation device has the advantages of being uniform in distribution, high in heating flux, free of thermal contact resistance, high in heating efficiency and rapid in temperature rise, the heating flux and the radius of a heating area are adjustable, heating boundary areas with different shapes and areas can be obtained by changing the shape and size of light-permissible holes of the visor, and the various requirements for high heating flux heating in the field of thermal testing and physical experiments can be met.

Description

technical field [0001] The invention relates to a simulation device for heating a surface, in particular to a lens-type simulation device for heating a surface with high heat flux, and belongs to the technical field of thermal measurement. Background technique [0002] At present, most of the laboratory simulations for heating surfaces with high heat flux are film heating, resistance wire heating and heating block heating. When using thin film heating, the difference in properties between the thin film and the heat sink material at high temperature will lead to huge thermal stress. When the resistance wire is heated, the heat flux density distribution will be uneven. The heating surface of the heating block and the heat sink surface have a large contact heat. Therefore, the high heat flux heating surface cannot meet the simulation requirements. [0003] The current simulation methods for heating surfaces with high heat flux have disadvantages such as low heat flux, large th...
