Single-side-heated external-heated thermal environment simulation device

Abstract

The invention relates to the technical field of artificial thermal environment simulation, and particularly discloses a single-side-heated external-heated thermal environment simulation device. The device comprises a heating box body and a temperature control system, wherein the inner walls of the bottom surface, the top surface and the two side surfaces of the heating box body are smooth metal planes, and the outer walls of the bottom surface, the top surface and the two side surfaces are of groove structures; heating layers are arranged in the grooves, and the heating layers are each coatedwith a heat insulation layer and an outer decorative surface; each heating layer is composed of heating wires which are sparse in the middle and densely arranged on two sides; the top surface heatingwires are sparsely arranged, and the bottom surface heating wires are densely arranged; the heating wires on the bottom surface and the top surface are respectively controlled by a temperature controlsystem, and the heating wires on the two side surfaces are controlled by another temperature control system. The device has the advantages that the heating wires are thin in the middle, thick on twosides, thin in the top surface and thick in the bottom surface, so that the temperature of the heating surface in the box body is more uniform, the temperatures of the surfaces are cooperatively controlled; one surface of the box body is buckled with a test sample, a stable artificial thermal environment simulating single-surface heating can be provided for the test sample, and two samples can betested at one time.

Description

technical field [0001] The invention relates to the technical field of thermal environment simulation devices, in particular to a thermal environment simulation device with one side heated and externally heated. Background technique [0002] Existing thermal environment simulation devices are equipped with heating devices on the bottom surface, the temperature uniformity inside the furnace body is poor, and there is only an insulating layer on the outer furnace wall, which often causes heat loss in the box body, which not only causes waste of resources, but also easily As a result, the control accuracy of the air temperature uniformity in the box cannot meet the actual requirements of the tested samples. Contents of the invention [0003] The purpose of the present invention is to provide a thermal environment simulation device with single-sided heating and external heating. The temperature of the heating surface of the box body is controllable and the surface temperature ...
