Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail using the drawings. In addition, elements attached with the same symbols in different drawings represent the same or corresponding elements.

[0025]

[0026] figure 1 It is a figure which schematically shows the structure of the environment formation apparatus concerning embodiment of this invention. In the example of the present embodiment, the environment forming device is configured as an environmental testing device 1 for evaluating the performance and the like of the test object 6 by applying a predetermined temperature and pressure to the test object 6 as the object. However, the environmental testing apparatus 1 may be configured as a constant temperature and humidity chamber in which a predetermined temperature pressure and humidity pressure are applied to the test object 6 by adding a humidifier. In addition, the environmental test apparatus 1 may be configured as an aging test a...

Abstract

An environmental test device (1) is provided with a test chamber (3) in which an object to be tested is accommodated; an air conditioning chamber (4) which is communicated with the test chamber; a cooler (11) and a main heater (12) for generating air-conditioned air by adjusting the temperature of air flowing into the air-conditioned chamber from the first wall surface (7) side of the test chamber; blowing fans (13) which are arranged side by side in a plurality of directions on the second wall surface (9) side of the test chamber facing the first wall surface (7), and which blow air-conditioned air from the air-conditioned chamber to the test chamber in the direction from the second wall surface (9) to the first wall surface (7); and a control unit (30) that individually controls the rotational speed of each of the plurality of blower fans (13). Therefore, the temperature distribution of the internal space of the test chamber (3) can be finely controlled.

Description

technical field [0001] The present invention relates to an environment forming device, and in particular, relates to an environment forming device capable of finely controlling the temperature distribution in an interior space of an environment forming chamber that accommodates objects. Background technique [0002] An environmental test is known as a test for evaluating the performance and the like of a test object such as an electronic component. In the environmental test, the performance and the like of the test object are evaluated by applying environmental pressure such as temperature to the test object accommodated in the test chamber. In addition, an environmental test apparatus is known as an apparatus for carrying out an environmental test. Background Art An environmental testing device includes: a test room surrounded by a heat-insulating frame; an air-conditioning room connected to the test room; an air-conditioning device such as a heater and a cooler arranged i...
