Example Embodiment

[0020] Example: see figure 1 shown:
[0021] A centrifuge and climate environment composite test equipment includes a centrifuge 1 and a climate box 2 .
[0022] The centrifuge 1 includes a base 11 on which a rotating arm 12 is arranged along a horizontal direction, and the middle of the rotating arm 12 is connected relative to the base 11 in a rotation around a vertical direction; a driving device 13 acts on the rotating arm 12 , the rotating arm 12 is driven to rotate relative to the base 11 by the driving device 13 . Both ends of the rotating arm 12 extend outward. One end of the rotating arm 12 is used as a load end, and the other end is provided with a balance block 121 as a balance end, and the rotating center of the rotating arm 12 is provided with a brush 14 .
[0023] The driving device 13 may adopt various power devices for driving rotation, and preferably the driving device 13 is composed of a motor 131 and a gear set.
[0024] The climate box 2 includes a thermal insulation box 21 , and the thermal insulation box 21 is fixed on the load end of the rotating arm 12 . The climate box 2 also includes a refrigeration unit, which includes a compressor 22 , a condenser 23 , an evaporator 24 and a fan 25 . The evaporator 24 is arranged in the thermal insulation box 21 , the condenser 23 , the compressor 22 and the fan 25 are arranged on the middle section of the rotating arm 12 , the compressor 22 , the condenser 23 and the evaporator 24 pass through the opposite rotating arm 12 . A fixed rigid conduit 26 communicates.
[0025] A temperature sensor 27 is also provided in the thermal insulation box 21. The temperature sensor 27, the compressor 22 and the fan 25 are connected to the brush 14 through the wire set 28 fixed on the rotating arm 12, so that the control signal is connected through the brush 14. .
[0026] In order to carry out the high temperature test, the thermal insulation box 21 is also provided with an electric heater 29 , and the electric heater 29 is also connected to the brush 14 through the wire group 28 fixed on the rotating arm, so that the electric heater 29 is connected through the brush 14 control signal.
[0027] According to the needs of the test, if the humidity needs to be precisely controlled, an electric humidifier, an electric dehumidifier and a humidity sensor (not shown in the figure) can be installed in the insulation box 21. The electric humidifier, electric dehumidifier and humidity sensor are also fixed by fixing The wire set 28 on the rotating arm is connected to the brush 14 , so that the control signal is connected through the brush 14 .
[0028] The thermal insulation box 21 is also provided with a camera 3, and the camera 3 is also connected to the brush 14 through the wire set 28 fixed on the rotating arm 12, so as to transmit a signal through the brush 14, so that the test piece can be observed at any time during the test. 4 status.
[0029] During the test of this embodiment, the test piece 4 is fixed in the thermal insulation box 21 of the climate box 2, and then the machine is turned on, the rotating arm 12 of the centrifuge 1 rotates, and the climate box 2 also starts to work, so that the test piece 4 is subjected to both centrifugal force and The role of a specific climate environment achieves the purpose of performing a composite experiment of centrifugation and climate environment, filling the gap in this field.
