Heat Pump Dryer Heat Exchanger Layout for Shorter Drying Cycles

The patent transitions from conventional single-layer or two-layer heat exchanger designs to a multi-layer stacked configuration. Multiple channels layers are arranged vertically one on top of another,充分利用 the vertical space within the heat exchanger housing. This dimensional transformation significantly increases the heat transfer surface area without proportionally increasing the horizontal footprint, thereby improving heat transfer capacity and reducing energy consumption.

The patent implements a nested structure where multiple channels layers are stacked within each other in a compact arrangement. Each layer contains multiple channels, and the layers are positioned one inside/above another, creating a space-efficient nested configuration. This nesting principle allows the heat exchanger to achieve high heat transfer capacity within a constrained volume, improving thermal efficiency without proportionally increasing size.

The patent resolves this contradiction by exploiting the vertical dimension through multi-layer stacking. Instead of expanding the heat exchanger horizontally, multiple channels layers are arranged vertically within a compact footprint. This allows the heat exchanger to maintain a small overall volume while achieving high heat transfer capacity through the cumulative surface area of multiple layers, effectively decoupling volume from heat transfer capability.

The heat exchanger is segmented into multiple independent channels layers, each containing multiple channels. This segmentation allows the total heat transfer surface area to be distributed across multiple layers, which can be stacked compactly. The segmented structure enables high heat transfer capacity to be achieved within a reduced overall volume by efficiently utilizing three-dimensional space.

The patent adopts a multi-layer stacked configuration where channels layers are arranged vertically, significantly increasing the heat transfer surface area within a compact structure. This dimensional transformation enhances the overall heat transfer capacity, enabling faster heating and cooling rates that shorten the drying cycle duration, while the modular layered structure remains relatively simple to manufacture.

Multiple channels layers are merged into a single integrated heat exchanger assembly, with each layer containing multiple channels. This merging of multiple heat transfer surfaces into one compact unit increases the total heat transfer capacity without proportionally increasing structural complexity. The unified multi-layer structure achieves high performance while maintaining manufacturing simplicity.
