Please refer to the following embodiments for details.

[0035] Example 1

[0036] See also Figure 1-Figure 3 , Figure 1 A schematic diagram of the structure of a dehumidification and drying device provided in an embodiment of the present application; Figure 2 Another structural schematic diagram of the dehumidification and drying device provided in this application; Figure 3 This is a schematic structural diagram of an embodiment of the electric heating element provided in this application.

[0037] like Figure 1-Figure 3 As shown, the dehumidification and drying device 10 includes a dehumidification and drying body 110 and an outer shell 200 .

[0038] The dehumidification and drying body 110 is arranged in the accommodating cavity inside the outer shell 200, wherein the outer shell 200 can be designed as a structure with a detachable panel to facilitate the placement of the dehumidification and drying body 110; or, the outer shell 200 can also be configured with an open surface structure on the bottom surface, so that the outer shell 200 can be mounted on the outside of the dehumidification and drying body 110 through the bottom surface to achieve the arrangement of the dehumidification and drying body 110 in the accommodating cavity inside the outer shell 200.

[0039] The dehumidifying and drying body 110 includes a cooling member 110 , a semiconductor element 120 and a heat conduction module 130 ; the cooling member 110 and the heat conduction module 130 are respectively disposed on both sides of the semiconductor element 120 .

[0040] The heat conduction module 130 includes a heat conduction member 131, an electric heating member 132 and a fan 133. The cold conduction member 110 and the electric heating member 132 are both connected to the heat conduction member 131. A plurality of heat sinks 13 are provided at one end of the electric heating member 132 away from the heat conduction member 131. The fan 133 is arranged opposite to the heat sink 13, and the air outlet of the fan 133 faces the heat sink 13.

[0041] The working principle of the dehumidification and drying device is as follows: when the semiconductor element 120 is powered on, the semiconductor element 120 generates a cold and heat effect, generating cold and heat. The cooling plate receives the coldness of the semiconductor and makes its temperature lower than the dew point temperature of water vapor, so that the water vapor in the air condenses into water and flows out, thereby achieving a dehumidification effect.

[0042] However, the heat generated by the semiconductor element 120 during cooling must be effectively discharged, otherwise the cooling efficiency will be reduced or even the semiconductor element 120 will be damaged. Therefore, the heat generated by the semiconductor element 120 during cooling can be quickly transferred to the electric heating element 132 by the heat conducting member 131 in the heat conducting module 130, and the heat is dissipated into the air through the heat sink 13 on the electric heating element 132, and the air flow is enhanced by the fan 133 to accelerate the heat dissipation.

[0043] In this embodiment, a cooling member 110 and a heat conducting module 130 are respectively arranged on both sides of the semiconductor element 120, so that when the semiconductor element 120 is powered on to generate a cooling and heating effect, the cold and heat are transferred through the cooling member 110 and the heat conducting module 130 respectively. The cooling plate receives the cold of the semiconductor and makes its temperature lower than the dew point temperature of water vapor, so that the water vapor in the air condenses into water and flows out, thereby achieving a dehumidification effect; and a heat conducting member 131, a fan 133 and an electric heating member 132 including a plurality of heat sinks 13 are arranged in the heat conducting module 130, so that the heat generated by the operation of the semiconductor element 120 can be transferred to the electric heating member 132 through the heat conducting member 131, so that the heat is transferred to the air through the heat sinks 13 on the electric heating member 132.

[0044] In addition, the fan 133 is arranged opposite to the heat sink 13, and the air outlet of the fan 133 is facing the heat sink 13. Through the cooperation between the fan 133 and the heat sink 13, the wind flow blown by the fan 133 can be directly applied to the heat sink 13, thereby enhancing air convection, so that the heat generated by the semiconductor element 120 can be dissipated more quickly, thereby improving the heat dissipation efficiency and ensuring that the dehumidification and drying device can still maintain a suitable working temperature under high load working conditions.

[0045] like Figure 1 and Figure 3 In some embodiments, the electric heating element 132 includes a first heat dissipation layer 1321 , a second heat dissipation layer 1322 , a heating pipe 1323 and an electric heating shell 1324 .

[0046] The first heat dissipation layer 1321 and the second heat dissipation layer 1322 each include a plurality of heat sinks 13, which can be made of a material with good thermal conductivity, such as aluminum alloy, to ensure that heat can be quickly and effectively transferred to the air.

[0047] The first heat dissipation layer 1321 and the second heat dissipation layer 1322 are installed on the electric heating shell 1324 and are relatively spaced apart along the width direction of the electric heating shell 1324 to form a double-layer heat dissipation structure, which can effectively increase the heat dissipation area.

[0048] The heating pipe 1323 is installed between the first heat dissipation layer 1321 and the second heat dissipation layer 1322, so that the heat generated by the heating pipe 1323 can be quickly and evenly distributed to the heat dissipation layers on the upper and lower sides, thereby optimizing the distribution of thermal energy and avoiding the problem of local overheating caused by excessive heat concentration.

[0049] Drying principle: When the electric heating element 132 is powered on, the heating tube 1323 generates heat energy and transfers the generated heat energy to the heat dissipation layers on the upper and lower sides, and blows it into the air through the fan 133, so that the air temperature increases, thereby reducing the relative humidity in the air, drying the air, and achieving a drying effect.

[0050] This example arranges a heating tube 1323 and a heat dissipation layer in the electric heating element 132, so that when the electric heating element 132 is powered on, the heating tube 1323 can generate heat and quickly dissipate it to the surrounding environment through the heat dissipation layer. Moreover, since the heat dissipation layer includes a plurality of heat sinks 13, the heat dissipation area can be greatly increased, thereby enhancing the heat exchange efficiency.

[0051] like Figure 3 As shown, in some embodiments, the heating tube 1323 is a U-shaped heating tube.

[0052] The heating tube 1323 includes a first sub-tube 101 , a second sub-tube 102 and a third sub-tube 103 .

[0053] Specifically, the first sub-tube 101 is installed between the first heat dissipation layer 1321 and the second heat dissipation layer 1322, and two ends of the first sub-tube 101 are connected to the second sub-tube 102 and the third sub-tube 103 respectively;

[0054] The second sub-tube 102 and the third sub-tube 103 are arranged relatively spaced apart and are respectively sandwiched between the second heat dissipation layer 1322 and the electric heating shell 1324 .

[0055] By adopting a U-shaped heating tube, the heat of the heating tube 1323 can not only be transferred to the upper and lower heat dissipation layers through the first sub-tube 101, but can also directly act on the electric heating shell 1324 through the second sub-tube 102 and the third sub-tube 103, so that the heat is evenly distributed in space, avoiding local overheating, ensuring the temperature balance of the entire electric heating element 132, and thus improving the heat utilization efficiency and heat dissipation effect.

[0056] In addition, the first sub-tube 101 is installed between the first heat dissipation layer 1321 and the second heat dissipation layer 1322, and the second sub-tube 102 and the third sub-tube 103 are arranged relatively spaced apart and respectively sandwiched between the second heat dissipation layer 1322 and the electric heating shell 1324, so that the limited space inside the electric heating element 132 can be fully utilized, the arrangement between the heating tube 1323 and the heat sink 13 is more compact, the space occupied inside the electric heating element 132 is reduced, and the miniaturization of the overall structure of the electric heating element 132 is achieved.

[0057] like Figure 1 As shown, in some embodiments, the dehumidification and drying body 110 further includes a mounting bracket 140; the mounting bracket 140 includes a first sub-bracket 141 and a second sub-bracket 142 that are fixedly connected.

[0058] The cooling element 110 and the semiconductor element 120 are embedded in the first sub-bracket 141 ; the heat conducting element 131 and the electric heating element 132 are embedded in the second sub-bracket 142 .

[0059] The cooling element 110 and the electric heating element 132 can be fixedly connected to the heat conducting element 131 by screws, respectively, and the semiconductor element 120 is embedded between the cooling element 110 and the heat conducting element 131 .

[0060] By respectively installing the cooling element 110 and the semiconductor element 120, and the heat conducting element 131 and the electric heating element 132 on different sub-brackets of the mounting bracket 140, thermal interference between the heat source and the cold source can be effectively avoided, the thermal management efficiency can be improved, and it can be ensured that the dryer can achieve efficient and stable dehumidification and drying functions during operation.

[0061] like Figure 1 As shown, in some embodiments, the second sub-bracket 142 is provided with a plurality of heat dissipation holes 1420 , and the heat dissipation holes 1420 are distributed on both sides of the second sub-bracket 142 along the height direction of the second sub-bracket 142 , and the size of the heat dissipation holes 1420 is adapted to the height of the electric heating element 132 .

[0062] By providing a plurality of heat dissipation holes 1420 in the second sub-bracket 142, the height of the heat dissipation holes 1420 can just cover the height range of the electric heating element 132. When the electric heating element 132 generates heat, the heat can be directly exchanged with the external environment through the heat dissipation holes 1420, thereby achieving efficient heat dissipation effect.

[0063] like Figure 1As shown, in some embodiments, the outer shell 200 is provided with an air inlet 210 and a plurality of air outlets 220 , the air inlet 210 is arranged along a side of the outer shell 200 close to the cooling member 110 , and the plurality of air outlets 220 are respectively communicated with the corresponding heat dissipation holes 1420 .

[0064] The air inlet 210 is arranged on a side of the outer shell 200 close to the cooling member 110, so that relatively cold external air can directly contact the cooling member 110, thereby helping the cooling member 110 to perform condensation and dehumidification operations more effectively. At the same time, the multiple air outlets 220 on the outer shell 200 are respectively connected to the heat dissipation holes 1420 on the second sub-bracket 142, so that the heat generated by the electric heating element 132 can enter the air outlet 220 through the heat dissipation holes 1420, and finally be discharged to the external environment, achieving a good heat dissipation effect.

[0065] In actual operation, air enters from the air inlet 210, passes through the cooling element 110 area for dehumidification, and then continues to flow to the heating element 132 area. The heat generated by the heating element 132 is transferred to the air outlet 220 through the heat dissipation holes 1420, forming an effective air circulation and heat exchange system.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the dehumidification and drying device further includes a water tank 300 and an intermediate support member 150. The outer shell 200 is detachably connected to the water tank 300 through the intermediate support member 150.

[0067] During the assembly process, the mounting bracket 140 can first be accurately inserted into the preset water outlet 151 position of the intermediate support 150 to ensure that the mounting bracket 140 is firmly connected to the water outlet 151 and does not affect the discharge path of the condensed water. Then, the cold conducting member 110, the semiconductor element 120, the heat conducting member 131 and the electric heating member 132 are embedded in the corresponding positions on the mounting bracket 140 in order to ensure that the electrical connection and heat conduction path between the components are correct. Then, a fan 133 is installed on the side where the heat sink 13 of the electric heating member 132 is located, so that the fan 133 can blow directly at the heat sink 13, thereby efficiently discharging the heat and completing the assembly of the dehumidification and drying body 110. After that, the assembled dehumidification and drying body 110 is placed in the accommodating cavity inside the outer shell 200, and finally connected to the water tank 300 up and down to ensure that the condensed water can flow smoothly into the water tank 300, so as to achieve effective water collection and treatment.

[0068] This embodiment designs a detachable water tank 300, which is convenient for the user to extract the water tank 300 for drainage at any time, avoiding water accumulation problems and ensuring long-term stable operation of the equipment. The outer shell 200 is connected to the water tank 300 up and down, which can reduce the space occupied by the dehumidification and drying device and improve space utilization.

[0069] like Figure 1 As shown, in some embodiments, the intermediate support member 150 is provided with a water outlet 151 , the mounting bracket 140 is plugged into the water outlet 151 , and the cooling member 110 is located on the water outlet 151 and arranged opposite to the water outlet 151 .

[0070] In this embodiment, a water outlet 151 is designed on the middle support member 150, and the cooling member 110 and the water outlet 151 are arranged relative to each other. In this way, when moisture condenses into water droplets on the cooling member 110, the water droplets will slide down along the surface of the cooling member 110 and finally flow into the water tank 300 below through the water outlet 151.

[0071] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, i.e., they may be located in one place, or may be distributed over multiple network units.
