Problems solved by technology

For example, due to the impossibility of exchanging the air in the test space with the air in the environment, temperature changes and relative air humidity changes may occur without significant losses during the test sequence despite the presence of openings in the walls and the use of vibrating devices. occur

Embodiment Construction

[0033] figure 1 A schematic cross-sectional view of a test chamber 10 with a test space 11 in which a test material 12 is arranged is shown. The test material 12 may be an accumulator or battery and can be exposed to defined temperature variations within the test space 11 . The test material 12 is rigidly positioned on the contact surface 13 of the vibrator 14 of the vibration device 15 such that the test material 12 can be exposed to vibrations of defined frequency and amplitude. The vibration device 15 also comprises a housing 16 towards which the vibrator 14 is movable relative to the direction of the arrow 17 . The vibrating device 15 also includes a base 18 on which the housing 16 is mounted to dampen vibrations.

[0034] The test space 11 is formed by temperature insulating walls 19 , 20 , and an opening 21 is formed in the wall 20 through which the vibration device 15 protrudes into the test space 11 . The gap 22 between the wall 20 and the vibration device 15 is sea...

Abstract

The invention relates to a method for testing a test material (12) in a thermally insulated test space of a test chamber (10) and to a test chamber. The test space is sealable with respect to the environment (26), and the test chamber comprises temperature control means for controlling the temperature of the test space and vibration means (15) arranged in an opening (21) formed in a wall (20) of the test space. The test material is arranged in the test space on a vibrator (14) of the vibration device, and a mechanical vibration of the test material and a temperature change in the test space are carried out in a test time period according to a predetermined test sequence. A gap (22) formed between the wall and the vibrating device is sealed by a flexible membrane (23) of the test chamber. A partition (24) of the test chamber connects the wall and the vibrating device. The separator is pressure-resistant and/or fire-resistant compared to the membrane.

Description

technical field [0001] The present invention relates to a test chamber and a method for testing a test material using the test chamber, in particular to a climate chamber for conditioned air comprising a thermally insulated test space capable of being sealed from the environment , a temperature control device for receiving test material and for controlling the temperature of the test space, the test chamber includes a vibrating device, the vibrating device is arranged in an opening formed in the wall of the testing space, and the test material is arranged in the vibrating device in the testing space On the vibrator, and according to the predetermined test sequence, the mechanical vibration of the test material and the temperature change in the test space are realized during the test period, and the gap formed between the wall and the vibration device is sealed by the flexible membrane of the test chamber. Background technique [0002] Test chambers are often used to test phy...
