Abstract
The utility model provides an environmental test chamber with an improved air-circulating system. The air-circulating system comprises a chamber body inner circulation device (2) for keeping the innerhumiture even, an air channel (4) arranged on one side of the chamber body, a movable air door (5) which is arranged on the side wall of the chamber body on the lower part of the air channel and canlead the air channel to communicate with the air outside the chamber body after being opened, a circulating fan (3) which is arranged upon the air channel (4) and used for exhausting the air in the air channel (4) to the chamber body inner circulation device (2), and a pressure relief hole (1) which is arranged on the top of the chamber body and can communicate the air inside the chamber body withthe air outside the chamber body after being opened, in this way, the original chamber body inner circulation device can be controllably communicated with air, so the heat and bad gas generated in the chamber body can be exhausted from the chamber body through the pressure relief hole.
Description
Technical field
The utility model relates to a kind of environmental test chamber, relates in particular to the environmental test chamber with improved air circulating system.
Background technology
Common humiture environmental test equipment, for example daylight simulation test case generally needs accurate temperature controlling in its testing laboratory when work.For reaching indoor even temperature, interior circulation air path is set in testing laboratory generally.Yet, when the long period is carried out in illumination in the chamber, can produce the higher ozone of concentration in the casing, when unpacking door after the off-test, higher ozone concentration can have a negative impact to peripheral local environment and operating personnel's health.
In addition, in casing, utilize when for example the power light source of xenon lamp and so on is made exposure experiments to light, can produce the thermal effect that adds that continues at box house.For addressing this problem, generally at present adopt that to be equipped with high-power cold mechanism cold, with required test temperature in the control casing, but increased the manufacturing cost and the operating cost of integral device like this.
Summary of the invention
For overcoming above-mentioned defective of the prior art, the purpose of this utility model provides a kind of improved environmental test chamber that helps dispelling the heat and discharge the air circulating system of bad air that has.
Environmental test chamber of the present utility model has air circulating system, and this air circulating system comprises: circulation 2 in the casing, and even in order to humiture in the maintenance casing; Air channel 4 is positioned at casing one side, and movable air door 5 is housed on the wall box of its underpart, and the outer atmosphere of described air channel and casing is communicated with; Circulating fan 3 is loaded on 4 tops, air channel, so that the row of the air in the air channel 4 is circulated 2 in casing; And pressure relief vent 1, be arranged at the casing top, the inside and outside atmosphere of casing is communicated with.
Like this, just making circulates in original casing controllably is communicated with atmosphere, the heat and the bad air part that produce in the casing can be discharged casing from pressure relief vent, can play cooling energy consumption and the effect that is beneficial to operator ' s health of saving.
Be described further below with reference to the technique effect of accompanying drawing, to understand the utility model fully concrete structure of the present utility model and generation.
Description of drawings
Fig. 1 is the synoptic diagram of environmental test chamber of the present utility model, shows air circulating system.
Embodiment
As shown in Figure 1, for having the humiture environmental test chamber of air circulating system.This circulation system comprises, circulation 2 in pressure relief vent 1, the casing; Circulating fan 3; Circulation 4 and self closing door 5 in the air channel.
During chamber work, circulation 2 operations are even with testing laboratory's humiture in the maintenance casing in the casing.Simultaneously, can open the circulating fan 3 of 4 tops, air channel that are installed on casing one side, row circulates 2 in casing with the air in the air channel 4, thereby forms negative pressure in air channel 4, and the top of circulation 2 in casing produces malleation.Because the existence of above-mentioned negative pressure and malleation, the outer atmosphere of casing can enter in the case by the movable air door 5 of air channel 4 downsides, and the air in the circulation 2 can part be discharged casing from the pressure relief vent 1 at casing top in the casing.Like this, just making circulates in original casing controllably is communicated with atmosphere, the heat and the bad air part that produce in the casing can be discharged casing from pressure relief vent 1.
Said structure has following two outstanding advantages: 1, and when exposure experiments to light carried out the long period, box house can produce concentration than high ozone, and this structure helps the timely eliminating of ozone gas, makes after the off-test security of operating personnel's operating equipment higher; 2, xenon lamp power is bigger, can add thermal effect what box house produce to continue, as does not have high-power cold machine coupling and can make the requirement of test temperature control be difficult to reach, this device makes the required refrigerating capacity reduction of temperature control comparatively obvious owing to be communicated with the outside ventilation effect that produces of casing, so can save energy.
Claims (1)
1. improved environmental test chamber of air circulating system is characterized in that described air circulating system comprises: circulation (2) in the casing, and even in order to keep in the casing humiture; Air channel (4) is positioned at casing one side, and movable air door (5) is housed on the wall box of its underpart, and the outer atmosphere of described air channel and casing is communicated with; Circulating fan (3) is loaded on top, air channel (4), with the row of the air in air channel (4) circulation (2) in casing; And pressure relief vent (1), be arranged at the casing top, the inside and outside atmosphere of casing is communicated with.
