Description

Environment testing equipment

Technical field

The utility model is about a kind of environment testing equipment; The environment testing equipment of especially relevant a kind of temperature, humidity measurement.

Background technology

Flourish along with various electronic product, the reliability test day of electronic product is paid attention to, wherein in order to also phase fractal key of the environmental testing of simulation electronic product user mode under varying environment.Be to change during the execution environment test with to be measured temperature, humidity in varying environment of environment testing equipment simulation.Generally speaking, this environment testing equipment comprises a hollow box body, and the tester can place this hollow box body with to be measured, to observe this to be measured performance in preestablishing environment, so as to assessing this performance of to be measured.Therefore,, will cause considerable influence, and then influence the accuracy of product efficacy assessment to be measured test result if this environment testing equipment can't simulate required environment exactly.

See also Fig. 1, it is the synoptic diagram for the environment testing equipment 1 of existing humiture test usefulness.This environment testing equipment 1 comprise a hollow box body 11, an air intake vent 13a and be located at fan 13b, the air outlet 13c of this air intake vent 13a, be located at a fan 13d and the controller 15 of this air outlet 13c.Hollow box body 11 has a plurality of sidewalls, as left side wall 17 and right side wall 13.This controller 15 is that in other words, the rotating speed of

fan

13b, 13d will be set at same rotational speed by controller 15 in order to the rotating speed of control fan 13b, 13d.Wherein, existing air intake vent 13a, air outlet 13c and

fan

13b, 13d only are arranged at the diverse location on these sidewalls sidewall wherein, for example are arranged on the right side wall 13.

As shown in Figure 1, this environment testing equipment 1 is in order to testing to be measured 19 different temperatures in prior simulation, the performance under the humidity environment, so as to assessing to be measured 19 fiduciary level.In operating process, because air intake vent 13a, air outlet 13c, fan 13b, the 13d of existing humiture environment testing equipment 1 all are positioned at same sidewall 13, therefore the air-flow of being exported by air intake vent 13a often can't be distributed in the hollow box body 11 equably.Specifically, shown in the direction of arrow among Fig. 1, the air-flow of being exported by air intake vent 13a will stop because of to be measured 19 volume own, and air outlet 13c is located at the cause of the air intake vent 13a top of same sidewall 13, hollow box body 11 is near the air current flow situation of sidewall 17, come not obviously, cause environment testing equipment 1 internal temperature, moisture distribution inhomogeneous, and then influence test result near sidewall 13.

In view of the above, any air-flow that overcomes existing temperature, humidity environment testing apparatus inside can't evenly distribute, and influences the shortcoming of simulated environment condition authenticity, and this operator who becomes this field leads and looks forward to the target that solves.
