Description
Technical field
The utility model relates to a kind of environmental test equipment, relates in particular to the environmental test equipment with air internal circulation system.
Background technology
Common environmental test equipment, especially humiture test box is when work, generally need accurately control temperature and humidity in its operating room, particularly the humiture uniformity in the operating room is had higher requirement, and the quality of the humiture uniformity depends on science, the reasonability of facilities air forced convertion internal circulation system.The internal circulation system of common employing axial-flow leaf, it can not change the airflow direction in the air channel, and it can only blow out along the direction of blade shaft, can form " blind area " in some places of operating room like this, thereby make the humiture uniformity of equipment not reach requirement.And adopt common centrifugal blower, still do not reach air-flow the abundant of all directions in the operating room and disperse.
The utility model content
For overcoming the above-mentioned defective of conventional test equipment, the purpose of this utility model provides a kind of environmental test equipment with internal circulation system, to reach the uniformity of higher operating room's humiture.
The environmental test equipment of band internal circulation system of the present utility model, its internal circulation system comprises: the operating room of described testing equipment back extend its bottom and the top between vertical air channel; Be positioned at the inlet scoop, air channel of bottom, air channel; Be positioned at the humidifier of inboard, inlet scoop, air channel; Be loaded on the motor of air channel top outer and by the leafy chip centrifugal impeller that is positioned at the air channel inside top of its driving; Spiral case, its inlet scoop and centrifugal impeller are installed on the air channel inwall with one heart; Heater is installed under the spiral case inlet scoop; Evaporimeter is positioned at internal heater below, air channel and humidifier top; Vertical adjuster is installed on the air outlet outside of spiral case, and its adjustable angle with chamber operating room rear wall saves.When described testing equipment is worked, air is inhaled into spiral case by the inlet scoop, air channel through humidifier, evaporimeter, heater because of the effect of centrifugal impeller, laterally sent from air outlet after fully discrete by centrifugal impeller in spiral case through the air of humidification, and all directions discrete type to the chamber operating room blows out after vertically adjuster is regulated, inlet scoop, air channel through the bottom sucks again, carries out the next round circulation.
Preferably, described spiral case comprises first Internal baffle, second Internal baffle and the 3rd Internal baffle that meets the involute Mathematical Modeling, in order to the air that centrifugal impeller is discrete with the different directions air outlet that leads; But described spiral case also comprises the portable plate of the lateral adjustments direction at air outlet place, flows out direction in order to the air that adjusts the air port.
Environmental test equipment of the present utility model, the air outlet of its internal circulation system by being positioned at top, operating room is sent air after the damping temperature adjustment with all directions, again through vertical adjuster of angle adjustable, vertical and transversely all discharge air to the operating room with a plurality of directions, be distributed in equably in the whole operating room, thereby can realize good humiture environment control.
Especially, have the effect of lateral adjustments wind direction through portable plate, the vertical adjuster of air outlet that install at degree of forming angle can vertically be regulated, and its air-out scope almost can cover whole operating room, can fully reduce the probability that work indoor circulation " blind area " occurs.
Description of drawings
Down will be in conjunction with the accompanying drawings the technique effect of concrete structure of the present utility model and generation be described further, to understand the utility model fully.
Fig. 1 is the schematic diagram of band internal circulation system environmental test equipment of the present utility model.
Fig. 2 is the enlarged diagram of spiral case shown in Figure 1.
The specific embodiment
As shown in Figure 1, be the schematic diagram of band internal circulation system environmental test equipment of the present utility model.The shell 9 that this testing equipment all has except conventional test equipment, the operating room 10, also comprised a cover internal circulation system.This internal circulation system comprises, motor 1, leafy chip centrifugal impeller 2, spiral case 3, nichrome formula heater 4, humidifier 5, high efficiency and heat radiation plate evaporator 6, vertical adjuster 7, inlet scoop 8, air channel 11.
A whole set of internal circulation system main body comprises the vertical air channel 11 that places the chamber back part.The inlet scoop 8 in air channel 11 is the reticulate perforation plate under the back, chamber operating room, and the humidifier 5 of inboard, inlet scoop is installed in the humidification tank of back bottom, chamber operating room.The motor 1 that is positioned at the top, air channel is customization major axis motor, the leafy chip centrifugal impeller 2 of its connection and driving air channel internal upper part; Spiral case 3 is fixed in the chamber inwall, and spiral case 3 inlet scoops are concentric with leafy chip centrifugal impeller 2; Nichrome formula heater 4 is installed under spiral case 3 inlet scoops, is fixed in inwall after the chamber; High efficiency and heat radiation plate evaporator 6 is installed on nichrome formula heater 4 belows and humidifier 5 tops, is fixed in inwall after the chamber; Before vertically adjuster 7 is installed on spiral case 3 air outlets, become miter angle respectively with chamber operating room rear wall and top.
During chamber work, humid air is inhaled into spiral case 3 by inlet scoop 8 by humidifier 5, evaporimeter 6, heater 4, humid air in spiral case 3 by centrifugal impeller 2 after the fully discrete and lateral adjustments, cooperating the vertical adjuster 7 of air outlet to regulate all directions discrete type of back to the chamber operating room blows out, suck through inlet scoop 8 again, carry out the next round circulation.
As shown in Figure 2, be the schematic diagram of spiral case 3.This spiral case comprises first Internal baffle 12, second Internal baffle 13, the 3rd Internal baffle 14, and they disperse arrangement from outside to inside; The preceding portable plate 15 that also comprises the air outlet place.Disperse along the tangential direction of blade by the humid air that centrifugal impeller 2 sucks, flow to air outlet through Internal baffle 12, Internal baffle 13, Internal baffle 14 by different directions, but the air outlet design has the preceding portable plate 15 of lateral adjustments direction, and humid air blows out from all directions discrete type through cooperating the vertical adjuster 7 of air outlet after the preceding portable plate 15 lateral adjustments directions.
Proportion relation according to hot-air, cold air, humid air is installed from top to bottom, and whole air flow is flowed along the air flow of centrifugal blower fully.The radian of Internal baffle 12, Internal baffle 13, Internal baffle 14 and arc length all are the diameter in strict accordance with centrifugal impeller 2, are got by the involute calculated with mathematical model, have tight scientific basis.This structure can make the wind bundle with minimum energy loss, and is smooth, be separated to different directions equably.Bigger air outlet angle: preceding portable plate 15 has the effect of lateral adjustments wind direction, the vertical adjuster 7 of air outlet that forms the miter angle installation can vertically be regulated, its air-out scope almost can cover whole operating room, can fully reduce the probability that work indoor circulation " blind area " occurs.
