Flow guide component for sand dust test boxand circulating air duct system

Abstract

The invention discloses a flow guide component for a sand dust test chamber and a circulating air duct system. The flow guide component comprises an upper support plate and a lower support plate, a plurality of flow guide sheets are mounted between the upper support plate and the lower support plate, the flow guide sheets are distributed in an array along the length direction of the upper support plate, and the flow guide sheets are of arc-shaped structures; and a flow guide channel with an arc-shaped structure is formed between two adjacent groups of flow guide sheets. The circulating air duct system comprises an air duct loop, the air duct loop is of a rectangular structure and is composed of four straight air ducts which are sequentially and vertically communicated, a flow guide component is arranged in a transition area of every two adjacent straight air ducts, and the two ends of each flow guide channel directly face the straight air ducts on the two sides of the flow guide component. The flow guide component has the beneficial effects that the flow guide component can be suitable for being mounted at the right-angle corner of an air duct loop, so that airflow smoothly flows through the right-angle corner, sand dust is prevented from being accumulated at the right-angle corner, and higher sand dust simulation quality in the air duct loop is ensured.

Description

technical field [0001] The invention relates to the technical field of sand and dust test chambers, in particular to a flow guide component and a circulating air duct system for a sand and dust test chamber. Background technique [0002] Sand and dust test chamber is a test device that can simulate a sand and dust environment. It can be used to test the performance of electrical products such as electrical appliances, motors, radiators, and electronic components in a sand and dust environment. [0003] In the prior art, sand dust test chambers mostly adopt a single air path structure design. In the process of testing products, it is necessary to continuously add sand to the test chamber, which consumes a large amount of sand, especially in the face of For products with high test standards, such as military products that need to be exposed to sand and dust for a long time, a larger amount of sand needs to be added continuously during the test process, which is not only time-c...

[0003] In the prior art, sand dust test chambers mostly adopt a single air path structure design. In the process of testing products, it is necessary to continuously add sand to the test chamber, which consumes a large amount of sand, especially in the face of For products with high test standards, such as military products that need to be exposed to sand and dust for a long time, a larger amount of sand needs to be continuously added during the test, which is not only time-consuming and labor-intensive, but also has high test costs
