高低温试验箱离心风机固定结构

High low temperature test box centrifugal fan fixed knot constructs

Abstract

The utility model discloses a high low temperature test box centrifugal fan fixed knot constructs, including testing box, the last several centrifugal fan that is equipped with of testing box, centrifugal fan set up in pairs and the position relative, centrifugal fan's air outlet with testing box's experimental space intercommunication, centrifugal fan's air intake with be equipped with a baffle between centrifugal fan's the air outlet, the baffle will centrifugal fan's air intake with centrifugal fan's air outlet cuts off. This centrifugal fan fixed knot constructs and sets up a baffle cut off both completely between centrifugal fan's air intake and air outlet, and the air that is blown by the air outlet play just so can not inhaled back by the air intake negative pressure again, guarantees that the air in the wind channel exchanges with air in the experimental space completely, rates with the air exchange in experimental space in the work efficiency and the wind channel of improving centrifugal fan like this, the intake in increase experiment space.
本实用新型公开了一种高低温试验箱离心风机固定结构,包括试验箱箱体,所述试验箱箱体上设有数个离心风机,所述离心风机成对设置且位置相对,所述离心风机的出风口与所述试验箱箱体的试验空间连通,所述离心风机的进风口与所述离心风机的出风口之间设有一隔板,所述隔板将所述离心风机的进风口与所述离心风机的出风口隔断。该离心风机固定结构在离心风机的进风口和出风口之间设置一隔板将两者完全隔断,这样由出风口出吹的空气就不会再被进风口负压吸回,保证风道里的空气与试验空间中的空气进行完全交换,这样提高离心风机的工作效率及风道与试验空间的空气交换率,增加试验空间的进风量。
