Abstract

PURPOSE:To enlarge the effective volume of a testing chamber by providing a cold/hot air switching damper and a separator plate with an air guide. CONSTITUTION:When a hot air switching damper 9 is opened as shown by solid lines with a hinge 9b as a pivot, a separator wall 9-1 is also opened with a hinge 9-1b as a pivot in an interlocked movement. Meanwhile, a cold air switching damper 2 remains closed. Likewise, a hot air switching damper 10 and a separator plate 10-1 are opened, while a cold air switching damper 3 remains closed. Under such a condition, the hot air blown out of a high temperature chamber 11 flows into a testing chamber 1 as the airflow direction is dictated as shown by the arrow mark by passing through air guides 9a, 9-1a, resulting in the uniform distribution of the hot air flow. The test specimen placed in the chamber 1 also gets the uniform airflow, resulting in the uniform time-temperature change rate. In this manner, the distribution of the cold or hot airflow in the test chamber 1 can be made uniform, and the effective space of the chamber 1 can be enlarged.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a thermal environment testing device, and particularly to a thermal environment suitable for improving the brocade distribution in a test room when cold air or hot air is distributed through the test chamber. This relates to testing equipment.

[Background of the invention]

The configuration and wind flow of a conventional thermal environment testing device will be explained with reference to FIGS. 1 to 3.

FIG. 1 is a schematic cross-sectional view of a conventional thermal environment test device, FIG. 2 is a sectional view taken along line A-A in FIG. 1, and FIG. 3 is a cross-sectional view taken along line B in FIG.
-B sectional view.

The cold environment test device is a heat shock test device that places a sample in a test chamber and alternately applies cold air and hot air environments, and is equipped with a test chamber, a cold room, and a high width room, each independently.

First, the configuration of the test chamber and the cold room and the flow of cold air will be explained with reference to FIGS. 1 and 3.

In the figure, 1 is a test chamber, and 4 is a cold room. Two cold air switching dampers on the cold air intake side and a cold air switching damper 3A on the cold air discharge side are installed in the part that separates the test room 1 and the cold room 4. ing.

5 is a cooler that cools the air in the cold room 4; 6 is a temperature control heater that adjusts and maintains the cooled air at a predetermined level; and 7,
A blower 8 for sending cooled air to the test chamber 1 is an electric motor directly connected to the blower 7.

Two cold air switching dampers and 3A are opened to supply cold air to the test chamber 1, and the cold air generated in the low width chamber 4, that is, the cold air that is cooled by the cooler 5 and maintained at a predetermined temperature by the regulating heater 6, is
Air is blown and circulated within the test chamber 1 by a blower 7 directly connected to an electric motor 8.

The cold air flows through the test chamber 1 as shown by the arrow and cools the sample placed in the test chamber. However, since it is difficult for cold air to flow toward the back of the test chamber, which is indicated by the two-dot chain line, it takes a long time for the temperature to change for the sample placed in the VC there, and the temperature change time varies depending on the placement position of the sample. However, there was a drawback that the effective range of the test chamber 1 was narrowed.

Next, the configuration of the test chamber and high temperature chamber and the flow of hot air will be explained with reference to FIGS. 2 and 3.

In the figure, 1 is the test chamber described above, 11 is a high temperature chamber, and the test chamber 1, low temperature chamber 4, and high temperature chamber 11 are each independent rooms, and their relative positions are as shown in FIG. . In FIG. 3, a low-ugliness chamber 4 is located on the right side of the test chamber 1, and a high temperature chamber 11 is located below the test chamber 1.

A hot air switching damper 9A on the hot air suction side and a hot air switching damper 1OA on the hot air discharge side are attached to the part that partitions the test chamber 1 and the high width room 11. The hot air switching damper 12 heats the air in the high temperature room 11. A heater, 13, is a heat storage body that stores heat from the heater 12 and holds the heated indoor air at a predetermined altitude; 14, a blower for sending the heated air to the test chamber 1; 15, a blower 14; It is an electric motor directly connected to the

Hot air to test chamber 1 is supplied by hot air switching dampers 9A and 10A.
The hot air generated in the high temperature chamber 11, that is, the heater 1
The hot air heated in step 2 and maintained at a predetermined altitude in the blood heat storage body 13 is heated in step 1. A blower 14 directly connected to an electric motor 15 blows air into the test chamber 1 to provide a circulation system. As the hot air flows through the test chamber 1 as shown by the arrow, it takes a long time for the temperature of the sample placed there to change, and the temperature change time varies depending on the placement position of the sample. Considering that a cold and hot recycle test is conducted in the test chamber 1, the effective test chamber volume Vit becomes smaller and smaller.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and it can uniformize the distribution of the flow of cold and hot air in the test chamber, thereby improving the temperature distribution, and making it possible to use a large effective volume of the test chamber. Its purpose is to provide a thermal environment testing device.
