[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 4 As shown, the semiconductor heat exchange component of this embodiment includes a semiconductor refrigeration plate 1, a laminar heat exchanger 2 and a driving mechanism 3, the laminar heat exchanger 2 includes a first heat exchange part 21 for exchanging cold at the cold end of the semiconductor refrigeration plate 1, the laminar heat exchanger 2 includes a second heat exchange part 22 for exchanging heat at the hot end of the semiconductor refrigeration plate 1, the first heat exchange part 21 and the second heat exchange part 22 respectively include multiple layers of annular blades 20, the driving mechanism 3 is used to drive the laminar heat exchanger 2 to rotate; an air inlet area 201 is formed between the through holes of the multiple layers of the annular blades 20, and an air outlet area 202 is formed between two adjacent layers of the annular blades 20.

[0027] Specifically, the hot and cold ends of the semiconductor cooling plate 1 in the semiconductor heat exchange assembly of this embodiment are heat exchanged through the laminar heat exchanger 2, wherein the two heat exchange parts in the laminar heat exchanger 2 are respectively composed of multiple layers of circular blades 20. When the driving mechanism 3 drives the laminar heat exchanger 2 to rotate, the circular blades 20 will rotate accordingly. The air between the two adjacent layers of circular blades 20 will flow to the outside of the circular blades 20 under the action of centrifugal force due to fluid viscosity, so that the air inlet area 201 formed at the through hole of the circular blades 20 generates negative pressure, thereby realizing the flow of air. Among them, the flowing airflow formed by the rotation of the multiple layers of circular blades 20 in the first heat exchange part 21 will realize the heat exchange treatment of the cold end of the semiconductor cooling plate 1, and the flowing airflow formed by the rotation of the multiple layers of circular blades 20 in the second heat exchange part 22 will realize the heat exchange treatment of the hot end of the semiconductor cooling plate 1. The annular blades 20 can function as a fan on the one hand, and can also function as a heat exchanger for the semiconductor refrigeration plate 1 on the other hand, so that the overall volume of the semiconductor heat exchange assembly of this embodiment is relatively small; at the same time, the rotation of the annular blades 20 realizes laminar air circulation, which can effectively reduce operating noise to improve user experience. In addition, the driving mechanism 3 may include a motor 31 and a rotating disk 32, wherein the motor 31 is used to drive the rotating disk 32 to rotate, and the laminar heat exchanger 2 is mounted on the rotating disk 32; and in order to enable the first heat exchange part 21 to better condense and dry the air, the laminar heat exchanger 2 is fixed to the rotating disk 32 through the second heat exchange part 22, and the first heat exchange part 21 can avoid being blocked by the rotating disk 32 and has better ventilation efficiency, so as to improve the efficiency of condensation and drying.

[0028] Furthermore, in order to improve the heat exchange efficiency so that the hot and cold ends of the semiconductor refrigeration plate 1 can exchange heat quickly and efficiently, the cold end of the semiconductor refrigeration plate 1 is connected to a first heat pipe 11, and the first heat pipe 11 is connected to the annular blades 20 of the first heat exchange part 21, and the hot end of the semiconductor refrigeration plate 1 is connected to a second heat pipe 12, and the second heat pipe 12 is connected to the annular blades 20 of the second heat exchange part 22. Specifically, the cold end and the hot end of the semiconductor refrigeration plate 1 are respectively connected to the annular blades 20 of the corresponding heat exchange part through the heat pipes, and the heat pipes can quickly transfer heat and use the annular blades 20 to quickly dissipate heat. Preferably, the first heat pipe 11 and the second heat pipe 12 respectively include an arc-shaped pipe portion 101 and a plurality of straight pipe portions 102 connected together, and the straight pipe portion 102 passes through the corresponding multiple layers of the annular blades 20. The arc-shaped pipe portion 101 is connected to the semiconductor refrigeration plate 1. Specifically, the first heat pipe 11 and the second heat pipe 12 are each composed of an arc-shaped pipe portion 101 and a plurality of straight pipe portions 102 connected together. The arc-shaped tube portion 101 in the first heat pipe 11 is composed of a plurality of straight tube portions 102. Taking the assembly of the first heat pipe 11 and the first heat exchange portion 21 as an example, a plurality of straight tube portions 102 are arranged on the arc-shaped tube portion 101 in the first heat exchange portion 21. Each straight tube portion 102 passes through the multiple layers of the annular blades 20 of the first heat exchange portion 21. The first heat pipe 11 can be used to quickly transfer the cold end of the semiconductor refrigeration plate 1 to each layer of the annular blades 20. During the rotation process, the annular blades 20 can not only drive the air flow, but also act as heat dissipation fins to quickly and efficiently exchange heat with the cold end of the semiconductor refrigeration plate 1. In addition, with respect to the first heat exchange part 21 and the second heat exchange part 22, the first heat exchange part 21 and the second heat exchange part 22 can be fixedly connected together by means of a connecting column or a connecting frame. Preferably, the first heat pipe 11 and the second heat pipe 12 are thermally insulated and fixed together. Specifically, the first heat pipe 11 and the second heat pipe 12 are fixedly connected, so that the first heat exchange part 21 and the second heat exchange part 22 are connected together through the first heat pipe 11 and the second heat pipe 12. In addition to being used for heat transfer, the heat pipe is also used to connect the two heat exchange parts, which is more conducive to simplifying the structure and reducing the volume.

[0029] Furthermore, a thermal insulation gasket (not shown) is provided on the periphery of the semiconductor refrigeration plate 1, a cold end heat conductive block 13 is provided on the cold end of the semiconductor refrigeration plate 1, and a hot end heat conductive block 14 is provided on the hot end of the semiconductor refrigeration plate 1, the thermal insulation gasket is sandwiched between the cold end heat conductive block 13 and the hot end heat conductive block 14, the first heat pipe 11 is connected to the cold end heat conductive block 13, and the second heat pipe 12 is connected to the hot end heat conductive block 14. Specifically, the cold end and the hot end of the semiconductor refrigeration plate 1 are heat-transferred through the heat conductive blocks connected to each other, and the heat conductive blocks can be better connected to the heat pipes to improve the heat transfer efficiency. Preferably, in order to make the overall structure more compact, the semiconductor refrigeration plate 1 is arranged between the first heat exchange part 21 and the second heat exchange part 22, and with respect to the air circulation flow mode of the first heat exchange part 21 and the second heat exchange part 22, as Figure 3 As shown, the air inlet area 201 of the first heat exchange part 21 and the second heat exchange part 22 are interconnected, so that the external air enters the laminar flow heat exchanger 2 through the air inlet area 201 of the first heat exchange part 21, and part of the air is condensed and dried after heat exchange with the annular blades 20 of the first heat exchange part 21 to form dry air output, and the remaining part of the air is output after heat exchange with the annular blades 20 of the second heat exchange part 22. In order to reduce the leakage of air from the interval area between the first heat exchange part 21 and the second heat exchange part 22, a windshield sleeve (not shown) is further provided between the first heat exchange part 21 and the second heat exchange part 22. The windshield sleeve is used to block the wind, and at the same time, the windshield sleeve can also play the role of connecting the first heat exchange part 21 and the second heat exchange part 22. Similarly, as Figure 4 As shown, the cold-end heat conductive block 13 and the hot-end heat conductive block 14 are both disc-shaped structures, and the cold-end heat conductive block 13 and the hot-end heat conductive block 14 separate the air inlet area 201 of the first heat exchange part 21 and the air inlet area 201 of the second heat exchange part 22, so that external air enters from the air inlet area 201 of the first heat exchange part 21 and the air inlet area 201 of the second heat exchange part 22 independently, and at the same time, is output from the air outlet area 202 of the first heat exchange part 21 and the air outlet area 202 of the second heat exchange part 22 independently.

[0031] Specifically, the semiconductor heat exchange component is installed in the installation cavity 42. During the drying process, the driving mechanism 3 drives the laminar heat exchanger 2 to rotate, and at the same time the semiconductor refrigeration plate 1 is energized. The air in the drying cavity 41 is sucked into the installation cavity 42 and enters the first heat exchange part 21 for condensation and drying. The dried air flows back into the drying cavity 41, and the clothes in the drying cavity 41 are dried in this reciprocating manner. Among them, the specific control method of the drying equipment includes a drying mode. In the drying mode, after the semiconductor refrigeration plate 1 is powered on, the driving mechanism 3 drives the laminar flow heat exchanger 2 to rotate, and the air between two adjacent annular blades 20 flows outward due to the viscosity of the fluid and the centrifugal force to generate negative pressure in the air inlet area formed by the annular blades 20. Under the action of the negative pressure, the air in the drying cavity 41 enters the air inlet area 201 of the first heat exchange part 21 through the return air port 401 and is condensed and dried by the cold released by the cold end of the semiconductor refrigeration plate 1. Then, the dry air enters the drying cavity 41 from the air outlet 402.

Preferably, a water retaining ring 422 is provided on the partition 421 at the periphery of the mounting hole, and a drainage hole (not shown) is also provided on the partition 421, and the drainage hole is connected to a drainage pipe (not shown).

A water collecting trough (not shown) is provided at the portion where the partition 421 is connected to the side wall of the upper cavity. Two adjacent water collecting troughs are interconnected, and the drainage hole is opened in one of the water collecting troughs.

Under the action of negative pressure, the air in the drying chamber enters the air inlet area of ​​the first heat exchange part through the return air port and is condensed and dried by the cold energy released by the cold end of the semiconductor refrigeration plate. Then, the dry air enters the drying chamber from the air outlet.
