Description
Technical field
The utility model relates to a kind of experimental rig, particularly the calm simulated environmental test device of one.
Background technology
The environmental test of precise electronic product needs to utilize special experimental rig to detect.The structure that simulated environmental test device general at present adopts has the adherent constant temperature structure of silicone oil and directly place heater free convection constant temperature structure in trial zone, what adopt is temperature in high wind circulation constant test device, the heat thing of testing sample itself can be walked, its wind speed often increases by 1 meter, its heat can reduce about 10%, therefore testing sample surface temperature does not conform to actual temperature, the electronic product high for test requirements document just loses real data.
Utility model content
The utility model to provide in a kind of trial zone without circulated air and the constant calm simulated environmental test device of test temperature.
In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:
A kind of calm simulated environmental test device, primarily of outer container and interior case composition, it is one independently salable trial zone that described interior case is arranged at outer box cavity, the gap-forming circulatory flow temperature adjustment district of outer container and interior case, temperature sensing device is provided with in described interior case and outer container, in circulatory flow temperature adjustment district, be provided with temperature-controlled package and guiding subassembly, described in it, guiding subassembly, temperature-controlled package are controlled by a control device.
Further, described interior case chamber wall adopts aluminium sheet to make, and the chamber wall of inner chamber is provided with fin type evaporating area, is provided with luggage carrier in the cavity of inner chamber.
Further, the temperature-controlled package arranged in described outer container cycling hot runner includes heater and condenser/evaporator, the centrifugal impeller that described guiding subassembly includes circulating fan and is connected with circulating fan.
Further, the turning that described outer box cavity installs guiding subassembly is right angle, and other turning is circular arc chamfering.
Further, the turning of the outer box cavity of the turning correspondence of described interior box outer wall is provided with a right angle and multiple circular arc chamfering equally.
Further, described outer container chamber wall is a kind of hollow-core construction being filled with insulation material.
The beneficial effect of calm simulated environmental test device described in the utility model is: the dual chamber adopting trial zone and temperature adjustment to distinguish designs, ensure that in trial zone without forced circulation, without free convection wind speed, reduce the master data of product to be tested, for the research and development of products test of client provides guarantee, temperature adjustment district adopts the air of independently outer air duct circulating-heating and refrigeration, the special full aluminium inwall conduction that energy is crossed by correlation data calculation, makes the temperature constant in trial zone.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, detailed description of the invention of the present utility model is described in detail.Obviously, described embodiment is only a part of embodiment of the present utility model, and other embodiment that those skilled in the art obtains under the prerequisite not paying creative work all belongs to protection domain of the present utility model.
The calm simulated environmental test device of one that theres is provided of the utility model as shown in Figure 1, form primarily of outer container 1 and interior case 2, it is one independently salable trial zone that described interior case 2 is arranged at outer container 1 inner chamber, the gap-forming circulatory flow temperature adjustment district 11 of outer container 1 and interior case 2, outer container chamber wall is a kind of hollow-core construction being filled with insulation material 3, temperature sensing device 12 is provided with in described interior case 2 and outer container 1, 21, temperature-controlled package and guiding subassembly is provided with in circulatory flow temperature adjustment district 11, the temperature-controlled package arranged in described outer container cycling hot runner temperature adjustment district includes heater 13 and condenser/evaporator 14, the centrifugal impeller 16 that described guiding subassembly includes circulating fan 15 and is connected with circulating fan, guiding subassembly described in it, temperature-controlled package is controlled by a control device.The chamber wall of described interior case 2 adopts aluminium sheet to make, and the chamber wall of inner chamber is provided with fin type evaporating area 22, is provided with luggage carrier 23 in the cavity of inner chamber 2.
As preferably, the turning that described outer box cavity installs guiding subassembly is right angle, other turning is circular arc chamfering, and the turning of corresponding interior box outer wall is provided with a right angle and multiple circular arc chamfering equally, and such corner structure design can allow circulating current play effect without pressure drop wind.
Concrete operation instruction:
Workpiece to be checked is positioned on the luggage carrier of interior case, in closing successively, chamber door and outer chamber door make experimental rig form two independently confined spaces, opened by control device, temperature adjustment is carried out by temperature-controlled package, guiding subassembly carries out water conservancy diversion to the temperature that temperature-controlled package sends makes it flow in cycling hot runner temperature adjustment district uniformly, each chamber wall of interior case absorbs its temperature conduction to the inner chamber of interior case to be tested workpiece to be checked, because interior case adopts totally-enclosed space, the calm wind speed that there is no Natural Circulation and cause, its full aluminium chamber wall conduction, make the temperature constant in trial zone, reduce the master data of product to be tested, for the research and development of products test of user provides guarantee.
Last it is noted that above embodiment is only for illustration of the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
