In one aspect, referring to fig. 1 and 3, a desiccant rotor apparatus according to an embodiment of the present invention includes a desiccant rotor 10 capable of adsorbing water vapor, a semiconductor refrigeration unit 20, a heat absorption unit 21 thermally connected to a cold end of the semiconductor refrigeration unit 20, and a heat dissipation unit 22 thermally connected to a hot end of the semiconductor refrigeration unit 20. Referring to fig. 2, the desiccant rotor 10 includes a cooling zone 10C, a regeneration zone 10B and a processing zone 10A, and the processing zone 10A, the regeneration zone 10B and the cooling zone 10C are sequentially arranged along the rotation direction of the desiccant rotor 10. The heat absorption unit 21 is disposed corresponding to the cooling area 10C to cool the cooling area 10C, and the heat dissipation unit 22 is disposed corresponding to the regeneration area 10B to heat the regeneration area 10B. Specifically, when the semiconductor refrigeration unit 20 is powered on, a temperature difference is established between the hot end and the cold end of the semiconductor refrigeration unit, the hot end becomes a high-temperature heat source, and the cold end becomes a low-temperature cold source; the low-temperature heat is transferred to the heat absorbing unit 21 through the heat conductive connection, so that the heat absorbing unit 21 also has a lower temperature, thereby cooling the cooling region 10C of the desiccant rotor 10. The high temperature heat is transferred to the heat dissipating unit 22 through the heat conductive connection, so that the heat dissipating unit 22 also has a higher temperature, thereby heating the regeneration region 10B of the desiccant rotor 10. The heat at the hot end is conducted away in time through the heat dissipation unit 22, and the heat at the cold end is conducted away in time through the heat absorption unit 21, so that a good temperature difference is maintained between the cold end and the hot end of the semiconductor refrigeration unit 20.
The division of the cooling zone 10C, the regeneration zone 10B, and the treatment zone 10A of the desiccant rotor 10 is not a division of the structure of the desiccant rotor 10, but a division of the function thereof.
Referring to fig. 2, the structure of the moisture absorbed by the desiccant rotor 10C in the processing region 10A will be described. Firstly, in the process that the moisture in the dehumidified air passes through the desiccant rotor 10 from one side of the desiccant rotor 10 in the processing area 10A, the moisture is adsorbed by the structure at the position C of the desiccant rotor 10, and the dehumidified air passes through the desiccant rotor 10 in the processing area 10A to become dry air; along with the rotation of the dehumidification rotating wheel 10, the structure at the position C rotates to enter the regeneration area 10B, the heat of the heat dissipation unit 22 is driven by external air flow to heat the structure at the position C, water vapor adsorbed in the structure at the position C is desorbed at high temperature and is taken away by the external air flow, and meanwhile, the temperature of the structure at the position C is passively raised; then, the structure at the position C rotates to the cooling area 10C, the heat absorption unit 21 cools the structure at the position C under the guidance of another external air flow, and meanwhile, the structure at the position C recovers the adsorption capacity; then, the structure at C enters the processing area 10A again to adsorb moisture again, and since the structure at C is cooled by the heat absorption unit 21 before entering the processing area 10A, the structure at C still has high dehumidification efficiency after entering the processing area 10A again, and the thermal influence of the regeneration area 10B on the dehumidified air is effectively reduced.
The dehumidification rotating wheel device provided by the embodiment of the invention has a simple structure and is ingenious in design, so that the dehumidification rotating wheel 10 can keep higher dehumidification efficiency, and the heat influence of the regeneration area 10B on the dehumidification air can be effectively reduced; furthermore, the semiconductor refrigeration unit 20 is used for providing a low-temperature cold source and a high-temperature heat source, refrigeration by using a refrigerant is not needed, and a complex circulating refrigeration system is not needed for realizing the refrigeration, so that a compressor, a condenser, an evaporator, a condensing agent and the like in the circulating refrigeration system are omitted, the dehumidifying rotary wheel device is simple and compact in structure, only occupies less installation space, and can be installed in a narrow space, so that the dehumidifying rotary wheel device is particularly suitable for dehumidifying household drying and dehumidifying equipment, and is beneficial to miniaturization and simplification of household drying and storing equipment.
The desiccant rotor 10 has a disk shape, and a rotor shaft mounting hole 101 is formed at the center thereof. The desiccant rotor 10 may be formed by coating particles capable of adsorbing water vapor on the surface of the substrate, or the substrate itself may be formed of a material capable of adsorbing water vapor, as long as it can adsorb water vapor.
The semiconductor refrigeration unit 20 is in the form of a sheet, for example a square sheet, to facilitate thermally conductive connection of the heat sink unit 22 to the hot side and to facilitate thermally conductive connection of the heat sink unit 21 to the cold side. Further, referring to fig. 3, the cold end is located on a side of the semiconductor refrigeration unit 20 close to the desiccant rotor 10, and the hot end is located on a side of the semiconductor refrigeration unit 20 away from the desiccant rotor 10, that is, the cold end is closer to the desiccant rotor 10 than the hot end. In this way, the heat absorbing unit 21 may more effectively cool the desiccant rotor 10. The distance between the heat absorption unit 21 and the desiccant rotor 10 is 3-10mm, for example, 3mm, 5mm, 8mm, 10mm, which can not only ensure that the heat absorption unit 21 has a good cooling effect, but also ensure that the rotation performance of the desiccant rotor 10 is not affected.
As the hot end is located at a side of the semiconductor refrigeration unit 20 away from the desiccant rotor 10, that is, the hot end is slightly distant from the desiccant rotor 10, in order to obtain a better heating effect and ensure the moisture desorption efficiency of the regeneration region 10B, please refer to fig. 3, the desiccant rotor apparatus according to the embodiment of the present invention further includes a heater 30, the heater 30 is located between the heat dissipation unit 22 and the desiccant rotor 10, the heater 30 can adjust the heating temperature of the regeneration region 10B, and ensure the heating effect of the regeneration region 10B, and meanwhile, the heat dissipation unit 22 fully utilizes the heat at the hot end of the semiconductor refrigeration unit 20, so as to reduce the energy input of the heater 30, which is beneficial to energy saving and consumption reduction.

The structure and heat conduction principle of the heat pipes in the heat pipe array are prior art and are not described herein again. Further, for convenience of installation, the first heat pipe array extends out from one side of the cold end of the semiconductor refrigeration unit 20, the second heat pipe array extends out from the other side of the hot end of the semiconductor refrigeration unit 20, and the length extension direction of the first heat pipe array is perpendicular to that of the second heat pipe array, so that convenience is provided for installation of the heat pipe arrays, convenience is also provided for a short distance of a central angle of about 90 degrees between the first heat pipe array and the second heat pipe array in the rotation direction of the desiccant rotor 10, the area of the processing area 10A is increased as much as possible, and the desiccant function is enhanced.

That is to say, the first partition frame 41 and the second partition frame 42 avoid the rotating shaft mounting hole 101 as much as possible, and the appearance shape of the overall structure is coordinated, so that the appearance of the desiccant rotary wheel device is improved. Further, in the projection on the desiccant rotor 10, the area enclosed by the first partition frame 41 occupies 20% to 30% of the area of the desiccant rotor 10, for example, 20%, 25%, 30%, etc., and this occupation ratio can ensure that the combination of the dehumidification efficiency and the desorption efficiency of the desiccant rotor 10 reaches the optimum state. Here, the "area of the desiccant rotor 10" refers to an area of the desiccant rotor 10 excluding the rotor shaft mounting hole 101.

Specifically, one end of the first air duct 61 and one end of the second air duct 62 are both communicated with the drying and dehumidifying chamber 502, the other end of the first air duct 61 and the other end of the second air duct 62 are spaced and correspond to each other, the processing area 10A is located at a junction of the other end of the first air duct 61 and the other end of the second air duct 62, that is, the circulating dehumidifying airflow generated between the circulating dehumidifying channel 60 and the drying and dehumidifying chamber 502 sequentially flows back to the drying and storing chamber through the first air duct 61, the processing area 10A of the dehumidifying rotor 10 and the second air duct 62.
