In order to evaluate the thermal insulation performance of the heat shield plate 1, which is an evaluation target by using such a device, the heat shield plate 1 is first placed on a plurality of lower support members 125 having lower ends fixed to a frame. By the operation of 125, the heat shield plate 1 is arranged to be spaced apart at a predetermined interval on the upper portion of the heat generating body (111).

That is, the heat shield plate is raised in contact with the contact bar 125g, and the contact bar 125g is assembled to the fourth clamp 125e of the horizontal support bar 125b, and thus the horizontal support bar 125b.

In addition, the first thermocouple 121 is in contact with the measuring end of the lower end on the surface of the heat generating body 111 by the operation of the upper support 124, the second thermocouple 122 is another upper support ( The third thermocouple 123 is fixed with the heat shield plate by the operation of another upper supporter 124 while the measurement end, which is the lower end, is brought into contact with the surface of the heat shield plate 1 by the operation of 124. Place them at intervals.

In this state, by supplying external power to the heat generating body heats a plurality of heating rods 113 disposed inside the cylindrical metal tube 112 to generate heat to dissipate high temperature heat from the surface of the heat generating body 111. Accordingly, the heat shield plate 1 is heated by heat provided from the heat generating body, but heat is blocked to the upper portion of the heat shield plate 1 to form a relatively low temperature.

Subsequently, the first, second and third thermocouples 121, 122, and 123 frequently measure the temperature of heat radiated upward after being blocked by the heat generating body 111, the heat shield plate 1, and the heat shield plate, and measured temperature values. Is transmitted to the temperature controller 132 side.

At this time, the PID controller 131 receives the heat generation temperature of the heat generating body 111 of the received temperature value and compares it with a preset temperature value so that the heat generating temperature provided by the heat generating body is reduced to a set temperature value. The power supply is controlled, and when the temperature reaches the set temperature value, the heating temperature is kept constant.

In addition, the measured temperature value received by the temperature controller 132 is recorded and stored in the recording and collecting device 141, the data recorded and stored in the recording and storage device 141 is transmitted to the terminal to be evaluated The thermal insulation performance of the thermal barrier plate is evaluated.
