Abstract
The invention discloses a rapid temperature variation testing machine, comprising a machine body and an experimental plot arranged in the machine body, wherein a motor is arranged on the wall surface of the experimental plot, the motor is connected with a fan, a cover body is arranged outside the fan, the cover body is provided with an air duct, two wind deflectors are arranged above the air duct, the sections of the wind defectors are in an arc shape, and the two wind deflectors are arranged in a staggered way; when air is sucked into the cover body, the air is respectively discharged from gaps between the wind deflectors and the cover body and enters into a convection current region; on one hand, the wind deflectors block the wind discharged from the air duct, on the other hand, the wind is guided outside from the two ends of the wind deflectors, thus the wind is uniform and the air flow in the experimental plot is balanced.
Description
Technical field
The present invention relates to a kind of testing equipment, be specifically related to fast temperature and change testing machine.
Background technology
Fast temperature changes testing machine and is mainly used in testing the control of environment of living in, to satisfy special requirement to temperature, humidity, that guarantees to test carries out and Related product quality stable smoothly, for example analog equipment is under the warm and humid combination condition of climatic environment, carry out that high/low-temperature impact, temperature speed becomes, hot and humid, low temperature and low humidity, condensation test or the like, the adaptive capacity of testing product itself or carry out the humiture stress screening of product.
Existing fast temperature changes testing machine, and the test block wall is provided with blower fan, and blower fan is outside equipped with a cylindrical shape cover body, the cover body top axial offers the wind groove, and the cover body upside is provided with the convective region, and the convective region is provided with grid, during fan starting, air is sucked cover body, enter the convective region through the air-supply groove and discharge from grid again, reach and circulate, when air forms wind and when the wind groove is discharged, not too even, cause the air in the test block mobile unbalanced, test is exerted an influence.
Summary of the invention
The fast temperature that the purpose of this invention is to provide a kind of air flow equalization changes testing machine.
The technical solution adopted for the present invention to solve the technical problems is: fast temperature changes testing machine, the test block, the test block wall that comprise body and be positioned at body are provided with motor, be connected with blower fan on the motor, blower fan is outside equipped with cover body, offer the wind groove on the cover body, described wind groove top is provided with wind deflector, and the cross section of wind deflector is an arc.
Described wind deflector has two, interlaced setting.
The invention has the beneficial effects as follows: after air is inhaled into cover body, discharge from the slit between wind deflector and the cover body respectively, and enter the convective region, because wind deflector stops the wind that the wind groove is discharged on the one hand, on the one hand wind is derived from the wind deflector two ends, the wind of Liu Chuing is more even like this, and air is mobile relatively more balanced in the test block.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
With reference to shown in Figure 1, fast temperature changes testing machine, and the test block 1, test block 1 wall that comprise body and be positioned at body are provided with motor 2, are connected with blower fan 3 on the motor 2, blower fan 3 is outside equipped with cover body 4, cover body 4 upsides are provided with convective region 5, and convective region 5 is provided with grid, offer the wind groove on the cover body 4, described wind groove top is provided with wind deflector 6, described wind deflector 6 has two, interlaced setting, and the cross section of wind deflector 6 is an arc.
When motor 2 drives blower fan 3 rotations, air circulates in test block 1, be inhaled into after the cover body 4, discharge from the slit between wind deflector 6 and 4 two walls of cover body respectively, and enter convective region 5, because the wind that wind deflector 6 is discharged the wind groove on the one hand stops that one side derives wind from wind deflector 6 two ends, the wind of Liu Chuing is more even like this, and air is mobile relatively more balanced in the test block 1.
The foregoing description is illustrative principle of the present invention and effect thereof only; and the embodiment of part utilization, for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (2)
