[0031] The fan control cabinet is installed with the wind turbine generator set. The environmental conditions are not easy to control. The wind turbine generator set requires high reliability. A large number of electronic and electrical components are used in the fan control cabinet. In a closed or semi-closed metal cabinet, humid air will affect the performance of the electrical components. Therefore, the inside of the fan control cabinet needs to be kept dry. The existing dehumidification method of the fan control cabinet often uses desiccant placed in the cabinet during the transportation of the fan control cabinet, which is not reusable. During the operation of the fan control cabinet, the air humidity is generally reduced by ventilation, air replacement and heating, or a dehumidifier is added to ensure the dryness of the air in the cabinet.
[0032] The electrical components in the fan control cabinet are heating components when working. If the temperature inside the cabinet is slightly higher than the environment outside the cabinet, when the absolute humidity is high, the introduction of cold air will easily lead to saturation of water vapor, and then condensation will occur, endangering the safety of the fan control cabinet; and the method of heating to reduce the humidity of the air requires high high temperature resistance of the components in the cabinet; and the heating method does not reduce the moisture content in the air. As the temperature drops, the humidity will rise again. Adding special dehumidification equipment will undoubtedly increase the cost of the fan control cabinet and is not easy to maintain.
[0033] In order to solve the above problems, the utility model proposes a heater structure, an adsorption dehumidification device and a fan control cabinet, aiming to provide a heater structure, an adsorption dehumidification device and a fan control cabinet that can circulate dehumidification, is low-cost, easy to maintain and has high stability. Figures 1 to 3 The present invention is a schematic structural diagram of an embodiment of the heater structure provided by the present invention.
[0034] Please refer to Figures 1 to 3In one embodiment of the utility model, the heater structure 100 includes a mounting base 1, a heating plate 2 and a moisture absorption part 3; the mounting base 1 is provided with a wiring point 11; the heating plate 2 is mounted on the mounting base 1 and is electrically connected to the fan control cabinet through the wiring point 11; the heating plate 2 takes the mounting base 1 as the bottom and is surrounded by a accommodating groove 21 with an opening along the circumference of the mounting base 1; the moisture absorption part 3 includes a first desiccant 31, which is accommodated in the accommodating groove 21.
[0035] The technical solution of the utility model adopts the first desiccant 31 to be accommodated in the accommodating groove 21, so as to perform adsorption and dehumidification on the inside of the fan control cabinet, thereby maintaining the dryness of the inside of the fan control cabinet; when the first desiccant 31 adsorbs humidity to a certain extent, the heating plate 2 heats the first desiccant 31 to restore it to a dry state, and then the first desiccant 31 can circulate and dehumidify the inside of the fan control cabinet, and has low cost, easy maintenance and high stability.
[0036] Furthermore, the moisture absorbing part 3 includes a physical desiccant. It is understandable that in some embodiments, the moisture absorption part includes a chemical desiccant, such as calcium chloride, or an alkaline desiccant, such as caustic soda, lime, or an acidic desiccant, such as concentrated sulfuric acid; they all have more or less great disadvantages and cannot perform the dehumidification function inside the fan control cabinet; for example, the use of a chemical dryer is easy to form hydrates with moisture in the air, resulting in an extremely short service life of the chemical dryer, requiring long-term replacement, thereby increasing costs and causing a great economic burden; and for alkaline desiccant, on the one hand, they will generate a large amount of heat when they absorb moisture, and this process is likely to cause thermal damage to the electronic components inside the fan control cabinet, and on the other hand, the reverse reaction of its dehydration needs to be completed at high temperature, and the heating plate 2 is absolutely unable to restore its reactant with water to itself, and thus the moisture absorption part cannot be recycled, and thus, it still needs to be replaced regularly, resulting in increased costs and a great economic burden; finally, for acidic desiccant, such as concentrated sulfuric acid, firstly, the cost of concentrated sulfuric acid itself is very high, and it is obviously used as an adsorption dehumidification agent. It is a waste of resources, and it will not be able to be recycled due to the heating of the heating plate 2. The cost of dehumidifying the fan control cabinet is huge; secondly, concentrated sulfuric acid gradually evolves into dilute sulfuric acid during the process of absorbing moisture. As we all know, concentrated sulfuric acid is a viscous liquid and is relatively controllable. However, as it absorbs more and more moisture, it evolves into dilute sulfuric acid. At the same time, it is inside the fan control cabinet, and it is difficult to guarantee that there will be no safety accidents. The strong corrosiveness of dilute sulfuric acid poses a great threat to the electronic components inside the fan control cabinet, and there are no sufficient means to control it, which is easy to cause safety accidents; therefore, the above-mentioned desiccants are not suitable, and therefore, the moisture absorption part 3 includes a physical desiccant material, and the physical dryer includes silica gel, activated carbon, etc. The dehumidification effect inside the fan control cabinet is completely due to its own physical adsorption effect, and no chemical change occurs. Under the heating effect of the heating plate 2, the moisture absorbed by the moisture absorption part 3 can also be dried, and then can be repeatedly recycled, further increasing the service life, reducing costs, and improving the economy of dehumidification.
[0037] In addition, it is understandable that in order to be able to visualize the dry and wet states of the hygroscopic part 3, it is necessary to replace the hygroscopic part 3 after it completely loses its effectiveness. Therefore, the material used in the hygroscopic part 3 can change its color according to its own water content, that is, the color depth of the hygroscopic part 3 changes step by step from a dry state to an adsorption saturated state. Therefore, the operator can judge whether the hygroscopic part 3 needs to be replaced through the human eye, thereby making it easy for the operator to replace it.
[0038] In addition, the heating plate 2 includes a resistance-type heating material. It is understandable that the heating method of the heating plate 2 may include electromagnetic heating or electric conduit heating, but these heating methods require the addition of additional devices, thereby increasing the economic cost. Therefore, the heating plate 2 includes a resistance-type heating material, and the resistance-type heating material makes the structure of the heating plate 2 simple and occupies less space, so that the space of the accommodating groove 21 is larger, and more of the first desiccant 31 can be accommodated. At the same time, the heating plate 2 using the resistance-type heating material has a simple heating method and a higher heating efficiency, thereby greatly reducing the cost.
[0039] In addition, please refer to Figures 1 to 3 , the heater structure 100 further includes a first fin 4, which is protruding outside the heating plate 2 along the length direction of the receiving groove 21. It can be understood that in order to accelerate the heat dissipation of the heating plate 2 and to dry the moisture inside the fan control cabinet more quickly through heat, the heater structure 100 further includes the first fin 4, which is protruding outside the heating plate 2 along the length direction of the receiving groove 21. Thus, the first fin 4 is extended on the heating plate 2, so that the heat generated by the heating plate 2 is dissipated more quickly into the fan control cabinet through the first fin 4, thereby accelerating the drying of the humid air inside the fan control cabinet, thereby ensuring the dryness of the inside of the fan control cabinet.
[0040] Furthermore, a plurality of the first fins 4 are provided, and a first clamping area 41 is formed between the plurality of first fins 4 ; the moisture absorbing part 3 includes a plurality of second desiccants 32 , which are respectively accommodated in each of the first clamping areas 41 . It can be understood that the first desiccant 31 inside the accommodating groove 21 has a limited moisture absorption area due to the encirclement of the heating plate 2. In order to better absorb the moisture inside the fan control cabinet, a plurality of first fins 4 are provided, and a first clamping area 41 is formed between the plurality of first fins 4; the moisture absorbing portion 3 includes a plurality of second desiccant 32, which are respectively accommodated in each of the first clamping areas 41. The second desiccant 32 is arranged between the plurality of first clamping areas 41, thereby increasing the moisture absorption area of the second desiccant 32. At the same time, a plurality of first clamping areas 41 are formed by the plurality of first fins 4, providing a good installation position for the second desiccant 32. Secondly, the provision of the plurality of first fins 4 accelerates the diffusion of heat from the heating plate 2. On the one hand, the moisture inside the fan control cabinet can be quickly dried, and on the other hand, the reduction of the second desiccant 32 can be accelerated, so that the second desiccant 32 can be recycled, thereby greatly saving costs.
[0041] In addition, please refer to Figures 1 to 3 , the heater structure 100 further includes a second fin 5, which is protruding outside the heating plate 2 along the width direction of the receiving groove 21. It can be understood that in order to accelerate the heat dissipation of the heating plate 2 and to dry the moisture inside the fan control cabinet more quickly through heat, the heater structure 100 further includes the second fin 5, which is protruding outside the heating plate 2 along the width direction of the receiving groove 21. Thus, the heat generated by the heating plate 2 is dissipated more quickly into the fan control cabinet through the second fin 5 by extending the second fin 5 on the heating plate 2, thereby accelerating the drying of the humid air inside the fan control cabinet, thereby ensuring the dryness of the inside of the fan control cabinet.
[0042] Furthermore, a plurality of the second fins 5 are provided, and a second clamping area 51 is formed between the plurality of second fins 5 ; the moisture absorbing part 3 includes a plurality of third desiccants 33 , which are respectively accommodated in each of the second clamping areas 51 . It can be understood that the first desiccant 31 inside the accommodating groove 21 has a limited moisture absorption area due to the encirclement of the heating plate 2. In order to better absorb the moisture inside the fan control cabinet, a plurality of second fins 5 are provided, and a second clamping area 51 is formed between the plurality of second fins 5; the moisture absorbing portion 3 includes a plurality of third desiccant 33, which are respectively accommodated in each second clamping area 51. The third desiccant 33 is arranged between the plurality of second clamping areas 51, thereby increasing the moisture absorption area of the third desiccant 33. At the same time, a plurality of second clamping areas 51 are formed by the plurality of second fins 5, providing a good installation position for the third desiccant 33. Secondly, the provision of a plurality of second fins 5 accelerates the diffusion of heat from the heating plate 2. On the one hand, the moisture inside the fan control cabinet can be quickly dried, and on the other hand, the reduction of the third desiccant 33 can be accelerated, so that the second desiccant 32 can be recycled, thereby greatly saving costs.
[0043] In addition, please refer to Figure 1The heater structure 100 further includes a detection device 6, which includes a humidity sensor 61 and a temperature sensor 62, which are installed on the mounting base 1 and electrically connected to the fan control cabinet. It can be understood that in order to further reduce power consumption, and because the fan control cabinet is filled with heating electronic components, the heating plate 2 is always heating, which is also a great test for the heat resistance of the components inside the fan control cabinet. Therefore, the heater structure 100 further includes the detection device 6, which includes the humidity sensor 61 and the temperature sensor 62, which are installed on the mounting base 1 and electrically connected to the fan control cabinet. Specifically, when the temperature inside the fan control cabinet is less than 5°C, or the humidity inside the cabinet is greater than 80% under the saturated state of the desiccant, the power of the heating plate 2 is turned on to restore the moisture adsorption capacity of the desiccant, and at the same time, the moisture inside the fan control cabinet is dried. Therefore, the heating plate 2 does not need to be kept on all the time, thereby greatly saving power and improving economy.

The specific structure of the heater structure 100 refers to the above embodiment.
