Flow equalizing adjusting plate for heat pump dryer

Abstract

The invention discloses a flow equalizing adjusting plate for a heat pump dryer. The flow equalizing adjusting plate comprises a plate body, first air outlet through holes, second air outlet through holes, third air outlet through holes, air return through holes and a partition plate, wherein the plate body is divided into an air outlet portion and an air return portion by the partition plate, the air outlet portion is sequentially provided with the first air outlet through holes, the second air outlet through holes and the third air outlet through holes from top to bottom, and auxiliary air outlet through holes are uniformly arranged near the central positions of the first air outlet through holes, the second air outlet through holes and the third air outlet through holes; the air return through holes are formed in the air return portion of the plate body, and auxiliary air return through holes are uniformly formed around the center positions of the air return through holes. By using the flow equalizing adjusting plate, through combined arrangement of the sizes and the position arrangement of the first air outlet through holes, the second air outlet through holes, the third air outlet through holes, the auxiliary air outlet through holes, the air return through holes and the auxiliary air return through holes, a flow speed of backflow air among the first air outlet through holes, the second air outlet through holes, the third air outlet through holes, the auxiliary air outlet through holes, the air return through holes and the auxiliary air return through holes is uniformly adjusted. According to the technical scheme, by adopting the combined arrangement, the air outlet through holes and the air return through holes are arranged in positions, so that the purpose of adjusting the air flow speed and a flowrate is achieved.

Description

technical field [0001] The invention belongs to the technical field of sheet metal parts and air conditioners, and in particular relates to a flow equalizing regulating plate for a heat pump dryer. Background technique [0002] The air source heat pump dryer adopts the air source heat pump technology to remove the moisture in the air, and absorb the moisture of the items to be dried by the dry air that removes the moisture, so as to complete the drying process of the items, due to its high efficiency Energy-saving features, more and more widely used. [0003] However, in the flow process of fan air supply, on a flow section, there is often the phenomenon that the air volume and wind speed are the highest in the middle position, while the air volume and wind speed at the upper and lower sides are smaller, which makes the flow through the heat exchanger The unevenness of the air has a great impact on the processing efficiency of the air, and finally there is a defect that the...
