Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further.
As shown in Figure 1 with Figure 2, a kind of high-low temperature test chamber, including casing 1, hermatic door 2, work chamber 3, refrigeration dress
Put, heating combined equipment, Programmable Logic Controller 4 and temperature control system, also include circulating fan 5, heater strip 6 and circulation air path, institute
The heater strip 6 stated and circulating fan 5 are located at the side of work chamber 3, and described circulation air path is located at work chamber 3 and circulated air
Between machine 5, described circulation air path includes that air inlet 7 and air outlet 8, described air inlet 7 are positioned at the upper end of work chamber 3,
Described air outlet 8 is positioned at the lower end of work chamber 3, and described air inlet 7 is provided with row's wind deflector 9, described working chamber
Being provided with slide rail 10 in room 3, described slide rail 10 is provided with shelf 11, and described hermatic door 2 is provided with inspection hole 12, described inspection
Window 12 lower end is provided with fairlead 13.Traditional testing machine air inlet 7 does not the most have wind deflector 9, it is impossible to freely control the angle of air intake
Degree, and in using circulating fan 5 as the circulation air path of major impetus, the Angle ambiguity of wind deflector 9 can play conclusive
Effect, has therefore redesigned air outlet 8 in strict accordance with Archimedian screw principle when of design, has made the air-flow of air outlet 8
Heater can be blown over equably, it is ensured that air-supply uniformly, makes trial target be heated evenly.
Preferably, described Programmable Logic Controller 4 is located on hermatic door 2, and described Programmable Logic Controller 4 lower end is provided with electricity
Source switch button 14 and inspection hole light switch 15.Part is provided with the equipment of inspection hole 12, or is not provided with special regarding
Examine window illuminating lamp, or together with the control switch of inspection hole illumination is mixed in programmable controller, so use the most not
Convenient, and being separately provided of inspection hole light switch 15, effectively solve this problem.
Preferably, the inspection hole 12 that described inspection hole 12 is square or circular, described includes the glass of multiple-layer stacked, phase
It is provided with heating wire between adjacent glass.Many experiments need the carrying out of observing response under certain environment, but in the change of high/low temperature
Usually can produce condensation and the phenomenon that hazes during change, impact is observed.And heating wire is set between compound glass and is possible to prevent
The dew condensation phenomenon of high temperature low temperature, it can be ensured that viewing test is carried out in order.
Preferably, described hermatic door 2 is hinged with casing 1, and described hermatic door 2 periphery and casing 1 periphery are equipped with resistance to
Elevated-temperature seal bar.Traditional way is to add one layer of sealing strip at casing 1 periphery, now due to the temperature range of user is increasingly
Width, for the sealing of more preferable guarantee test case, can respectively add a circle sealing strip on casing 1 with hermatic door 2, double insurance,
Sealing reliability is higher, and hermatic door 2 uses low-disturbance handle simultaneously, easy to operate succinctly.
Preferably, described slide rail 10 quantity is 6 right, and described shelf 11 number is more than or equal to 1, described slide rail 10
It is 304 rustless steels with the making material of shelf 11.The shelf 11 of traditional experiment case standard configuration is typically only two-layer, when user places
Time a fairly large number of, two-layer can not meet use requirement, so the number of plies of shelf 11 is increased 6 layers by this equipment, and
And can arbitrarily dismantle, so it is also convenient for client root and can freely control the quantity of shelf 11 according to practical situation when in use
And the distance between shelf 11, the spacing of shelf 11 is arranged flexibly, is possible to prevent the distance between shelf 11 too near, affects work
Make the circulation of the gas in chamber 3 and make the inequality of being heated of trial target.
Preferably, described casing 1 side is provided with pressure relief vent 16；Described air outlet 8 is provided with drainage screen 17；Described
A diameter of 13CM ~ the 25CM of fairlead 13.Traditional test lead hole 13 is to be opened on the left of casing 1, is used for switching on power or quilt
Test sample product and the extraneous purposes needing and connecting, but need to reach into now with a lot of clients, trial target is operated, institute
So that traditional fairlead is opened on hermatic door 2, mix protective gloves, can outside in bound pair casing 1 sample grasp
Make.
This high-low temperature test chamber good seal performance, studio space utilization rate is high, and shelf multilamellar can arrange flexibly, uses spirit
Live, and the trial target in operating room can thermally equivalent, improve experimental result, inspection hole will not haze, and does not affect observation, tool
There is experiment effect good, simple operation, it is easy to the advantages such as popularization.
Every technical staff's notice: although this utility model describes according to above-mentioned detailed description of the invention, but this
