Single-surface heated and external heating thermal environment simulator

Abstract

The invention relates to the technical field of artificial simulation of thermal environment and specifically discloses a single-surface heated and external heating thermal environment simulator. Thethermal environment simulator comprises a heating box body and temperature control systems. The inner walls of the bottom surface, top surface and two side surfaces of the heating box body are smoothmetal planes, and the outer walls thereof are of a groove structure. Each groove is internally provided with a heating layer. The heating layer is externally wrapped by a heat insulation layer and anexterior facing. The heating layer is formed by heating wires sparse in the middle and dense at the both sides. The heating wires on the top surface are sparsely arranged, and the heating wires on thebottom surface are densely arranged; the heating wires on the bottom surface and the top surface are respectively controlled by one temperature control system; and the heating wires at the two side surfaces are controlled by another temperature control system. The advantages are that the heating wires are sparse in the middle and dense at the both sides, and sparse on the top surface and dense onthe bottom surface, thereby making the temperature of the heating surfaces in the box more uniform; cooperative control of temperature on each surface is realized; and by buckling one surface of thebox body to a test sample, a stable simulation one-surface-heated artificial thermal environment can be provided for the test sample, and two test samples can be tested 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 ...
