Abstract

PURPOSE:To enable an effective area to be promptly cooled or heated to a desired temperature by partitioning at least a portion of the effective area by a thin plate spaced apart from the inner wall surface of the test area. CONSTITUTION:A high temperature air conditioner, a low temperature air conditioner and an outside air supply device are communicated with the test area 1 through a gas blowout port 21 and suction port 22, a gas blowout port 31 and a suction port 32 and a gas blowout port 41 and a suction port 42, respectively. A piller 12 is mounted upright in the vicinity of the left and right wall surfaces of the area 1 and an arm 13 is projectedly provided to each pillar for supporting a basket holding the sample. Partitioning plates 51, 52 are provided to the pillar 12 as encircling the test area 10 from left and right sides. In testing, the sample is set in the area, the door is closed, the ports 21, 22, 31, 32, 41 and 42 are selectively opened by the damper operation to perform high temperature exposure, low temperature exposure and outside air exposure tests in a predetermined sequence. Since the area 10 is surrounded by the partitioning plates 51, 52, it is heated or cooled prompty to the desired temperature.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention is applicable to various equipment parts, the equipment itself, etc.
The present invention relates to an environmental testing device such as a thermal shock device that tests the thermal stress characteristics, durability, thermal strength, etc. of articles by exposing them to a low-temperature atmosphere or outside air.

Conventional technology and its problems.

Conventionally, the test area of this type of test equipment was obtained by surrounding a metal plate layer such as stainless steel plate on the inside, a metal plate layer such as iron plate on the outside, and a wall with a heat insulating material layer arranged between the inner and outer layers. There is. In such a test device, there is a temperature difference between the central part of the test area and the vicinity of the inner wall of the test area (especially when heating or cooling starts), and there is a need to support a basket containing the specimen near the inner wall. Because there may be pillars installed in the test area, the zone was sometimes used as an effective area from the center from a position set back from the inner wall of the test area.

When specifying an effective area and placing a sample in that area, it is sufficient to heat and cool the effective area to the desired temperature, but the effective area can be used as a test area without any partitions. Since the test area was connected to the inner wall surface, when trying to heat or cool it, the inner wall of the test area and, in some cases, the layers outside of it must also be heated or cooled, which makes it difficult to bring the effective area to the desired temperature. This took time and resulted in energy loss.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an environmental test device that can heat or cool an effective area to a desired temperature more quickly than in conventional environmental test devices.

Means for Solving Problems The above-mentioned object of the present invention is to provide an apparatus for performing a temperature environment test by placing a specimen in an effective area within a test area, in which at least a portion of the periphery of the effective area is placed within the test area. This is achieved by an environmental testing device characterized by partitioning with thin plates placed away from the wall.

According to the present invention, a gas retention layer is formed between the effective area within the test area and the inner wall surface of the test area by the thin plate partition plate, and the layer between the gas within the effective area and the inner wall of the test area is formed. The heat transfer is reduced accordingly, and the heat capacity of the effective area becomes smaller. The partition plate can be made of various materials such as metal and synthetic resin, but the smaller the heat capacity and the lower the heat transfer coefficient, the better.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, one embodiment of the present invention will be described using a thermal shock test apparatus as an example with reference to the drawings.

The device shown in the figure has a high-temperature air conditioner (2) above a test area (1), a low-temperature air conditioner (3) below, and an outside air supply device (4) behind the test area. Area (1) is surrounded by a wall (11) made of a stainless steel plate as an inner layer, an iron plate as an outer layer, and a heat insulating material between the inner and outer layers.

*AI air conditioner (2) communicates with the test area (1) via a gas outlet (21) and an inlet (22), and these ports (21) and (22) are connected to a damper (23).
It is opened and closed at (24) and (24).

The low-temperature air conditioner (3) communicates with the test area (1) via a gas outlet (31) and an inlet (32), and these ports (31) and (32) communicate with the damper (33) and ( 34). The outside air supply device (4) includes a gas outlet (41) and a suction port (4).
These ports (41) and (42) are connected to the test area (1) through dampers (43) and (44).
) is opened and closed.

A net (30) is placed over at least the communication ports (31) and (32) to the low temperature air conditioner (3) on the bottom wall of the test area to prevent the sample from falling.

Pillars (12) are erected near the left and right inner walls of the test area (1), and each company points toward the effective area (10).
An arm (13) for supporting a basket (not shown) containing the sample
) is provided protrudingly.

Partition plates (51) and (52) are attached to the pillar (12) so as to surround the effective area (10) from left and right.

Each partition plate is an epoxy resin plate approximately 0.5111 mm thick. The upper ends of the partition plates (51) and (52)
1, 22>, and the lower ends of the partition plates face the right and left ends of the communication ports (31, 32).

In such a thermal shock device, in order to perform a test, the specimen is theft into the test area (1), and then m (14)
Close the communication port (21, 22), (31, 32) or (41, 42) to the test area (1) by operating the damper.
may be selectively opened to perform a high temperature exposure test, a low temperature exposure test, and an outside air exposure test in a predetermined order.

Note that FIG. 1 shows a high temperature exposure test state.

In this device, the effective area (10) is surrounded by partition plates (51) and (52) on the left and right sides, so when starting the insect temperature exposure test, low humidity exposure test, and outside air exposure test, the effective area (10) ) is heated or cooled to the desired temperature that much more quickly. In the above embodiment, the partition plates were provided on the left and right sides of the test area, but if necessary to enclose the effective area, the partition plates may be placed above, below, etc. of the test area as appropriate.

Effects of the Invention As described above, according to the present invention, an effective area can be heated or cooled to a desired temperature more quickly than in conventional environmental test equipment, and therefore high-temperature air conditioning with the same capacity as in conventional equipment can be achieved. Even with the use of low-temperature air conditioning equipment, even more rigorous tests can be performed efficiently. Another advantage is that it can provide an environmental testing device that saves energy when performing tests to the same extent as conventional tests.

The invention is particularly advantageous when the effective area has to be heated or cooled rapidly.
