The temperature that optical module generates diffuses on test board 31, and when fan 50 rotates forward, air is from test board 31 and support plate It between 221 periphery carries out, is then discharged by fan 50, forms cross-ventilation, be conducive to keep support plate 221 and test board Environment temperature between 31 is relative constant, when temperature is constant, starts to be calibrated；When temperature is not constant, by controlling wind The speed of fan 50, can accelerate thermal balance, reduce invalid operation.

When calibration finishes, fan 50 stops to stationary state, and then fan 50 starts to invert, and fan 50 blows to test peace Dress portion 32, effectively radiates, and prevents heat ageing.

The present embodiment bottom plate 10, mounting plate 212 and support plate 221 are equipped with engraved structure, effectively keep air flowing, Be conducive to keep the environment temperature between support plate 221 and test board 31 relative constant.

The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all Under the inventive concept of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or Directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
