Abstract

The utility model is a roasting test box, which comprises a gate, air openings, two baffles and a test area. The air openings comprise an air inlet at the bottom of the box and an air outlet at the top of the box. The two baffles are a lower baffle and an upper baffle, which are parallel to each other and are arranged near the air inlet and the air outlet respectively. A first opening and a seconding opening are arranged between opposite sides of the two baffles and the interior wall of the box respectively. The test area is arranged between the two baffles and at least a carrier plate, which is parallel to the baffles at the internal side of the test area. A secondary air area is arranged between each carrier plate and the interior wall of the box respectively to communicate with the first opening and the second opening, so air flowing through a carrier plate does not flow through another a carrier plate to avoid the problem of the accumulated temperature. Thus, an inspector can exactly find out the sample with problems.

Description

The baking test box

Technical field

The utility model is a kind of baking test box, the baking test box of the accurate specimen performance of especially a kind of energy.

Background technology

Please referring to shown in Figure 5, some electric equipment products such as power supply unit (PSU) must be inserted before dispatching from the factory in the baking test box through the environment temperature test, the baking test box of commonly using is to comprise at least one test layer 31, and each test layer 31 does not communicate, these test layer 31 both sides are respectively equipped with air intake vent 32 and air outlet 33, this test layer 31 33 is being put a plurality of PSU undetected objects 20 to be measured in regular turn from air intake vent 32 to air outlet, allow air enter test layer 31, flow out via air outlet 33 again from air intake vent 32.

Yet, because from air intake vent 32 to air outlet 33, the fluid tediously long runner of flowing through, and PSU can emit used heat again when test, and raising environmental testing temperature, therefore high more from the near more then environmental testing of air outlet 33 temperature, usually the big appointment of air themperature of flowing out from air outlet 33 promotes more than 20 ℃ than the air themperature that air intake vent 32 enters, so make near the PSU of air outlet 33 different easily with the environmental testing temperature at air intake vent 32 places, produce the problem that each PSU temperature test condition differs, and allow the testing staff think that these PSU have problem by mistake, this not only wastes testing staff's time, and what make more that the dealer worries is to find out real bad PSU effectively.

Summary of the invention

This creator is because commonly use the baking test box, the environmental testing temperature homogeneity is not good in the casing, and can't be really and find out bad electric equipment products effectively, therefore pass the viewpoint coupled computer analogue system of learning with heat, through constantly test and research, utility model goes out this baking test box finally again.

The purpose of this utility model is to be to provide a kind of inner air mobile smooth and easy, even baking test box with accurate specimen performance.

For reaching above-mentioned purpose, baking test box of the present utility model, it is a casing, and comprises:

Door is a side of being located at casing;

The air port, it is to comprise air intake vent that is arranged on bottom half and the air outlet that is arranged on the casing top;

Two baffle plates, it is to be parallel to each other and to be located at the lower baffle plate and the overhead gage at nearly air intake vent and air outlet place respectively, be provided with first opening between lower baffle plate one side and cabinet wall, be provided with second opening that first opening with lower baffle plate staggers mutually between this overhead gage one side and cabinet wall;

The test section, it is arranged between two baffle plates, and inner is provided with at least one board that is parallel to baffle plate, is respectively equipped with two flow area that are communicated with first opening and second opening between this board and cabinet wall.

Be to allow undetected object be placed on board or the lower baffle plate during test, allow air enter in the casing via first opening by the air intake vent of casing below earlier, principle by thermal convection flows toward air outlet place, top again, because being communicated in first opening of air intake vent is provided in a side of on the staggered position with second opening that is communicated with air outlet, therefore flowing through wherein, the air of a board can't flow through another board again, so do not have the problem that temperature adds up, so can avoid some board to bear higher air themperature, so the testing staff can accurately check out problematic sample.

Embodiment

Please referring to shown in Fig. 1-2, baking test box of the present utility model, it is a rectangular box, and comprises:

Door 11, it is arranged on the front side of this casing;

The air port, it is to comprise air intake vent 12 that is arranged on bottom half and the air outlet 13 that is arranged on the top of casing;

Two baffle plates, it is to be parallel to each other and to be located at the rectangle lower baffle plate 14 and the overhead gage 15 at nearly air intake vent 12 and air outlet 13 places respectively, this lower baffle plate 14 is with respect to being provided with first opening 141 between the opposite side of door 11 and cabinet wall, and this lower baffle plate 14 is closely to be connected with cabinet wall adjacent to the both sides of first opening 141, and be provided with opening 144 in subtend on the lower baffle plate 14 with respect to first opening 141, this overhead gage 15 is with respect to being provided with second opening 151 between opening 144 homonymies and the cabinet wall, and this overhead gage 15 both sides adjacent with second opening 151 are closely to be connected with cabinet wall;

The test section, it is arranged on, between the lower baffle plate 1415, and inside is provided with at least one baffle plate 14 that is parallel to, 15 board 16, each board 16 is with respect to last,

lower baffle plate

14,15 also are connected with cabinet wall with identical two opposite sides that cabinet wall connects, in addition two opposite sides be with cabinet wall between be respectively equipped with relative and be communicated with first flow area 18 and second flow area 19 of first opening 141 and second opening 151, and this first and second flow area 18, be provided with between board 16 in 19 wherein at least one flow area and cabinet wall and help cross-ventilated auxiliary blower 17.

Please referring to shown in Figure 3, on being somebody's turn to do, lower baffle plate 14 ', 15 ' be to be the L type, on being somebody's turn to do, lower baffle plate 14 ', 15 ' one sides are to be arranged at cabinet wall, and this side is provided with perforation, this cabinet wall also is provided with respect to this perforation and is provided with screw, be somebody's turn to do in order to do making, lower baffle plate 14 ', 15 ' can be with screw 142,152 pass, lower baffle plate 14 ', 15 ' perforation and be screwed in the screw of cabinet wall, going up, lower baffle plate 14 ', 15 ' be fixed on the cabinet wall, therefore this cabinet wall can be provided with screw in different positions, allows, lower baffle plate 14 ', 15 ' can be arranged on different positions according to different needs.
