The existing temperature test box has the following defects: during the experiment, the compressor unit operation of temperature test case, fan rotate, and even the produced vibration of cooling water pipeline internal water flow all can transmit to the objective table in the test case on through the rigid frame of temperature test case.
Temperature test box manufacturers have worked a great deal on the damping of the compressor unit of the test box. For example, a damping spring and a damping rubber pad are arranged at the bottom of the compressor unit, so that vibration transmission between the compressor unit and a bottom plate of the temperature test box can be reduced; the compressor unit air suction and exhaust pipeline uses a metal shock absorbing hose, and the vibration transmission between the pipelines is reduced by using the self elastic expansion function of the metal shock absorbing hose; and the mode of shock absorption bending and far-end fixing is adopted to avoid resonance of each pipeline. These compressor-train shock-absorbing measures greatly reduce the intensity of the stage vibration, but do not completely eliminate it. Even if the box with compressor unit and proof box adopts split type design, the vibration of compressor unit still can transmit to the proof box through ground. The fan of proof box, the condenser that is used for the cooling water heat transfer all with proof box rigid connection, though can reduce its fan and condenser to the vibration influence of proof box through the mode of installation vibration isolator, nevertheless vibration still can't eliminate completely.
Therefore, it is necessary to take thorough and effective measures to solve the vibration problem of the optical-mechanical product during the test.
