Description
Technical Field
The invention belongs to the technical field of switch cabinets, and particularly relates to an intelligent switch cabinet with temperature and humidity regulation control.
Background
The switch cabinet is used as important equipment in a power system, and the temperature and humidity environment inside the switch cabinet plays a vital role in the safety and stability of the operation of the switch cabinet. The electronic devices in the switch cabinet can continuously emit heat to the surrounding when in work; if the external temperature is too high, the external temperature can be continuously transmitted to the switch cabinet, and the internal temperature of the switch cabinet can be rapidly increased under the condition of double heating of the inside and the outside. However, the temperature threshold exists in the electronic components inside the switch cabinet, and when the ambient temperature is overheated, the aging of the circuit can be accelerated, so that the service life of the whole switch cabinet is gradually reduced.
When the switch cabinet is operated in a wet environment, water vapor can enter the switch cabinet through a gap of the switch cabinet, and when the temperature in the switch cabinet is gradually reduced, the water vapor in the switch cabinet can be gradually condensed along with the reduction of the temperature to form water drops. And the water drops can cause problems of partial discharge, short circuit and the like, and finally the whole switch cabinet is in fault.
Therefore, in order to ensure the normal operation of the switch cabinet, proper temperature and humidity adjustment is required.
In the prior art, the air with lower external temperature is generally introduced into the switch cabinet through the fan, and the low-temperature air returns to the outside again after heat exchange with the electric components in the switch cabinet is finished, so that the cooling work is completed. And humidity control is to heat the air in the switch cabinet through the heating mechanism, so that the condensation of water vapor on the electrical component is avoided, and the heated air and water vapor are sent to the outside by the fan to finish the dehumidification work.
However, the heating points in the switch cabinet are not uniformly distributed, if external cold air is simply introduced into the switch cabinet for cooling, although the flowing air coverage range is wide, the heating points cannot be cooled mainly, and therefore the problem that the cooling speed of the heating points is low is solved. For humidity adjustment, although heated air and water vapor are sent to the outside, the outside air sent into the switch cabinet by the fan still contains a large amount of water vapor, so that the fan and the heater can continuously work, and the fan can gradually stop working until the outside air humidity is reduced to a limiting value, and therefore, the energy consumption of the dehumidification system is excessively high.

The orientations related to the specification are all based on the orientations of the intelligent switch cabinet with temperature and humidity regulation control during normal operation, the orientations during storage and transportation are not limited, and only the relative positional relationship is represented, and the absolute positional relationship is not represented.
Example 1:
as shown in fig. 1-7, the scheme provides an intelligent switch cabinet with temperature and humidity regulation control, which comprises a cabinet body 1, wherein an adjusting bin 2 is arranged at the bottom of the cabinet body 1, and the cabinet body 1 comprises an installing bin 11 and a summarizing bin 12. In the prior art solutions, the installation magazine 11 is used for installing the various electrical components used for the switchgear, and the function of the induction magazine 12 is to comb the line trend. In order to avoid the problems of water vapor condensation and the like caused by overhigh temperature or overlarge humidity in the cabinet body 1, a temperature and humidity control component is generally installed in the induction bin 12. However, in view of insulation, the temperature and humidity control assembly is often limited in size, so that the temperature and humidity control assembly is small in size and light in weight. Because the cabinet body 1 is in a sealed environment, the air flow speed is slow, so that the heating and dehumidifying capacities of the temperature and humidity control assembly are slower, and the effect is poor.
For this reason, this scheme has introduced regulation storehouse 2, install fan 3, temperature adjustment mechanism 4 and humidity control mechanism 5 in the regulation storehouse 2. Wherein, the fan 3 is used for providing power for the movement of the air flow in the cabinet body 1; the temperature regulating mechanism 4 is used for heating air in the cabinet body 1 (the installation bin 11 and the storage bin) and preventing the inside of the switch cabinet from causing the problem of water vapor condensation when the switch cabinet is in an environment with high humidity; the humidity adjusting mechanism 5 is used for dehumidifying the air in the cabinet 1 to reduce the humidity, and then sending the dehumidified air into the cabinet 1 again.
In order to facilitate air flow inside the sealed cabinet body 1, a plurality of air outlet mechanisms 6 are arranged on the side wall, close to the installation bin 11, of the induction bin 12, an air outlet 60 of each air outlet mechanism 6 faces the installation bin 11, and an air inlet 31 matched with the air outlet 60 is arranged on one side, far away from the induction bin 12, of the installation bin 11. The air outlet mechanism 6 is matched with the air inlet 31, so that an air circulation duct is formed in the mounting bin 11. The air outlet mechanism 6 is used for sending air processed by the temperature adjusting mechanism 4 or the humidity adjusting mechanism 5 into the cabinet body 1, and air which is not processed in the cabinet body 1 is extruded by new air, so that old air can enter the air inlet 31, and circulation is completed.
In order to facilitate air circulation, an air inlet pipeline 32 is arranged between the air inlet 31 and the fan 3, a first pipeline 33 is arranged between the fan 3 and the humidity adjusting mechanism 5, old air in the cabinet body 1 is replaced by new air, the old air enters the air inlet 31 under the extrusion of the new air, then reaches the fan 3 along the air inlet pipeline 32, the fan 3 compresses the old air and then sends the compressed air to the first pipeline 33, and the air reaches the humidity adjusting mechanism 5 along the first pipeline 33 for dehumidification. After dehumidification, air enters the temperature adjusting mechanism 4 for heating, and the heated air returns to the cabinet body 1 again through the air outlet mechanism 6, wherein the aim of the selection is to replace humid air in the cabinet body 1 by dry high-temperature air so as to complete dehumidification. For this purpose, a second conduit 51 is installed between the humidity control mechanism 5 and the temperature control mechanism 4. Secondly, the dehumidified air directly returns to the cabinet body 1, so that the purpose is to cool the high-temperature electronic devices in the cabinet body 1 and ensure the normal operation of the high-temperature electronic devices. In order to make selection convenient, a first three-way valve 41 is arranged between the temperature regulating mechanism 4 and the air outlet mechanism 6, a third pipeline 42 is arranged between the temperature regulating mechanism 4 and the first three-way valve 41, a fourth pipeline 52 is arranged between the humidity regulating mechanism 5 and the first three-way valve 41, and an air outlet pipeline 61 is arranged between the first three-way valve 41 and the air outlet mechanism 6. When the humidity sensor 66 in the cabinet body 1 detects that the humidity is too high, the first three-way valve 41 closes one end of the fourth pipeline 52, and at the moment, air sequentially passes through the fan 3, the first pipeline 33, the humidity adjusting mechanism 5, the second pipeline 51, the temperature adjusting mechanism 4, the third pipeline 42, the first three-way valve 41, the air outlet pipeline 61 and the air outlet mechanism 6 to finish the dehumidification work; when the temperature sensor 65 in the cabinet body 1 detects that the temperature of certain devices is too high, air sequentially passes through the fan 3, the first pipeline 33, the humidity adjusting mechanism 5, the fourth pipeline 52, the first three-way valve 41, the air outlet pipeline 61 and the air outlet mechanism 6, the dehumidified low-temperature air is sent into the cabinet body 1, and then the low-temperature air exchanges heat with heating devices in the cabinet body 1, so that the purpose of cooling is achieved.
In this scheme, play fan mechanism 6 and air intake 31 are a plurality of, and a plurality of play fan mechanism 6 can set up with the electronic device cooperation in the cabinet body 1, and its purpose is so that the flowing air from play fan mechanism 6 can arrive the device that generates heat faster for the cooling rate of the device that generates heat. The air inside the cabinet body 1 can flow in a self-circulation mode due to the existence of the fan 3, the introduction amount of external air is reduced, the switch cabinet can realize that the internal air is in a dry state only by self-circulation for two to three times in a humid environment, the working time of a dehumidifying mechanism is shortened, and the consumption of energy sources is reduced. Due to the self-circulation of the air, the air self-circulation device reduces the introduction of the external air and the probability of suspended particles in the external air entering the cabinet body 1, thereby reducing the floating ash problem in the cabinet body 1.

In this scheme, the humidity adjusting mechanism 5 works on the principle that when normal temperature or high temperature air enters a low temperature environment, the moisture contained in the air can be quickly condensed on the surface of a low temperature object to form water drops or frost. Therefore, the humidity adjusting mechanism 5 includes a dehumidifying cavity 53 and a heat dissipation cavity 54, a plurality of semiconductor cooling fins 55 are installed between the dehumidifying cavity 53 and the heat dissipation cavity 54, the semiconductor cooling fins 55 include a cooling surface 551 and a heat generating surface 552, the cooling surface 551 is located at the top of the dehumidifying cavity 53, and the heat generating surface 552 is located at the bottom of the heat dissipation cavity 54. The semiconductor cooling fin 55 is a heat transfer tool, and when a current passes through a thermocouple pair formed by combining an N-type semiconductor material and a P-type semiconductor material, heat transfer occurs between the two ends, and the heat is transferred from one end to the other end, so that a temperature difference is generated to form a cold end and a hot end. By this property, the blower 3 sends air to the dehumidifying chamber 53 to dehumidify, and after the dehumidification is completed, the humid air becomes dry cool air, and then the dry cool air is re-introduced into the cabinet 1 to replace the humid air.

The second three-way valve 34 divides the air sent to the humidity adjusting mechanism 5 by the fan 3 into two parts, one part is sent to the dehumidifying cavity 53 for cooling and drying, the other part enters the heat radiating cavity 54 through the first heat radiating pipe 543 and then exchanges heat with the heat generating surface 552, and the hot air after heat exchange is discharged outside through the second heat radiating pipe 544 to complete heat radiating work. In this scheme, the second three-way valve 34 can be opened at the same time to connect with the cooling air pipe 341 and the first heat dissipation pipe 543, and can also be opened by self-selection according to the requirement.
In order to further increase the heat dissipation efficiency of the heating surface 552, a U-shaped heat pipe 553 is installed in the heat dissipation cavity 54 and is matched with the heating surface 552, a middle region of the U-shaped heat pipe 553 is connected with the heating surface 552, and two ends of the U-shaped heat pipe 553 are connected with a plurality of heat dissipation fins 554. The design ensures that the two ends of the U-shaped heat pipe can transfer heat to the heat dissipation fins 554, thereby accelerating the heat transfer speed between the heat dissipation fins 554 and the heating surface 552; the heat dissipation area of the heat generating surface 552 is increased by the heat dissipating fins 554, so that more heat can be taken away when air flows, and the heat dissipation efficiency is increased.
When the air dehumidifies by circulating flow, the low-temperature air flowing out of the humidity adjusting mechanism 5 needs to be heated by the temperature adjusting mechanism 4 and then enters the cabinet 1 through the air outlet mechanism 6, however, a large amount of energy is consumed in the process for heating the low-temperature drying air. In order to reduce the energy consumption, the heat dissipation cavity 54 includes a first cavity 541 and a second cavity 542, the first cavity 541 is located between the dehumidifying cavity 53 and the second cavity 542, the heat generating surface 552 is located at the bottom of the first cavity 541, two ends of the U-shaped heat pipe 553 penetrate through the top of the first cavity 541 to enter the second cavity 542, a portion of the heat dissipation fins 554 are located in the first cavity 541, and another portion of the heat dissipation fins 554 are located in the second cavity 542. One end of the second pipeline 51 is connected with the temperature adjusting mechanism 4, the other end of the second pipeline 51 is connected with the first cavity 541, a third three-way valve 56 is installed between the fourth pipeline 52 and the humidity adjusting mechanism 5, a bleed air pipeline 561 is installed between the first cavity 541 and the third three-way valve 56, a cold air pipeline 562 is installed between the dehumidifying cavity 53 and the third three-way valve 56, and the first radiating pipe 543 and the second radiating pipe 544 are respectively located at two ends of the second cavity 542. The design makes the low-temperature dry air flowing out of the dehumidifying cavity 53 have two paths, namely, the dehumidifying cavity 53, the cold air pipeline 562, the third three-way valve 56, the fourth pipeline 52, the first three-way valve 41 and the air outlet mechanism 6, at the moment, the third three-way valve 56 closes the air entraining pipeline 561 end, and the path realizes the refrigerating function. Secondly, the dehumidifying cavity 53, the cold air pipeline 562, the third three-way valve 56, the air-entraining pipeline 561, the first cavity 541, the second pipeline 51, the temperature regulating mechanism 4, the third pipeline 42, the first three-way valve 41 and the air outlet mechanism 6 are arranged, at the moment, the third three-way valve 56 closes the end of the fourth pipeline 52, and the path realizes the dehumidifying function; in this path, the dry cold air enters the first cavity 541, exchanges heat with the U-shaped heat pipes 553 and the heat dissipation fins 554 in the first cavity 541, and is preheated, and the temperature rises; the preheated cold air enters the temperature regulating mechanism 4 to be heated, and the temperature of the air is higher, so that the air is heated to a preset value, the speed is higher, the consumed energy is less, and the waste heat in the first cavity 541 is reused by the design, so that the waste of energy sources is reduced to the greatest extent. If the temperature is reduced by the first cavity 541, the working efficiency of the cooling surface 551 still cannot be maximized, so that the second cavity 542 is introduced, a part of the air guided by the fan 3 is sent to the second cavity 542 through the first heat dissipating tube 543, and the air is discharged through the second heat dissipating tube 544 after the heat exchange is completed. By double ventilation of the first cavity 541 and the second cavity 542, the heat dissipation speed of the heating surface 552 is increased, and the refrigeration efficiency of the refrigeration surface 551 is ensured.
Since the area of the cooling surface 551 is limited, only the cooling surface 551 is used for cooling, and the vapor condensation rate is limited. For this reason, be provided with a plurality of condensation nets 555 that cooperate with refrigeration face 551 in the dehumidification chamber 53, condensation nets 555 are provided with heat-conducting plate 556 towards the one end of refrigeration face 551, the one end that condensation nets 555 kept away from refrigeration face 551 is connected with the fixed plate, heat-conducting plate 556 and refrigeration face 551 heat conduction are connected, fixed plate and dehumidification chamber 53 bottom fixed connection. The condensation screen 555 and the heat conducting plate 556 enlarge the heat exchange area of the refrigerating surface 551 and the air, so that the air can be cooled down rapidly, water in the air can be condensed on the condensation screen 555 to form water drops, and the water drops are collected towards the bottom of the dehumidifying cavity 53 along the condensation screen 555 under the action of gravity. Preferably, the heat conductive plate 556 is welded to the cooling surface 551 or bonded by a heat conductive adhesive.
In order to accelerate the condensation speed of the water vapor on the basis of not influencing the air flow, the condensation net 555 is a stainless steel net, and the mesh aperture of the condensation net 555 is 0.8-1.5 mm.
In order to collect the condensed water droplets conveniently and guide the water droplets to the outside, the bottom of the dehumidifying chamber 53 is connected with a water storage chamber 57, the bottom of the dehumidifying chamber 53 is conical, and the bottom of the water storage chamber 57 is provided with a water outlet 571.
In this embodiment, the cabinet 1 is a sealed environment, but the inside and outside air flows due to the line crossing, that is, when the air circulates, part of the air reaches the outside of the cabinet 1. In order to supplement air, the two sides of the regulating bin 2 are respectively provided with a first ventilation opening 22 and a second ventilation opening 23, a sealing shell 24 is arranged in the regulating bin 2, a three-way pipe 25 is arranged between the sealing shell 24 and an air inlet pipeline 32, an exhaust pipeline 26 is arranged between the three-way pipe 25 and the first ventilation opening 22, one end, far away from an air inlet 31, of the air inlet pipeline 32 is connected with the three-way pipe 25, and the three-way pipe 25 is connected with the sealing shell 24 in a pipeline manner. The purpose of this scheme adoption double vent is to guarantee the vent inlet of one end, and the vent of one end is given vent to anger, and two vents are noninterference each other. For this, the blower 3 is located between the thermal insulation bin 21 and the first ventilation opening 22, and the second heat radiation pipe 544, which discharges hot air to the outside, is disposed toward the second ventilation opening 23.
In this scheme, in order to reduce suspended particles in the outside air from entering the cabinet 1, so that internal air circulation is preferentially ensured, and therefore, the three-way pipe 25 is in an all-open state when connected with the air inlet pipe 32, and the air suction pipe 26 is provided with the flow control valve 261, wherein the flow control valve 261 only maintains a partially-open state.
Preferably, the opening rate between the flow control valves 261 is 20% to 40%. The opening rate not only limits the external air to enter the cabinet body 1, but also ensures that the cabinet body 1 is internally positive in pressure, so that more air in the cabinet body 1 reaches the outside through the line opening, but also the external air enters the cabinet body 1 through the line opening, and the speed of floating and sinking accumulation in the cabinet body 1 is reduced. If the opening rate is lower than 20%, the problem that the internal air overflows too fast to cause negative pressure in the cabinet body 1, and then the internal air circulation cannot be completed is faced. If the opening rate exceeds 40%, the humidity control mechanism 5 and the temperature control mechanism 4 are pressurized, so that the energy consumption is excessive.
In order to avoid suspended particles entering the internal circulation through the fan 3, external air needs to be filtered, as shown in fig. 5 and 7, a first filter screen 221 is installed on one side of the first ventilation opening 22 away from the second ventilation opening 23, a second filter screen 222 is installed on one side of the first ventilation opening 22 close to the second ventilation opening 23, and the first filter screen 221 is connected with the outer wall of the regulating bin 2 through bolts; the fixed frame 223 is installed on one side of the first ventilation opening 22 facing the second ventilation opening 23, the fixed frame 223 includes an upper support arm 2231 and a lower support arm 2232 that are oppositely disposed, a limit rail 2233 is disposed at one end of the upper support arm 2231 facing the lower support arm 2232, and one end of the lower support arm 2232 facing the upper support arm 2231, the second filter screen 222 includes a filter screen 2221 and a square support frame 2222 disposed around the filter screen 2221, and top and bottom of the square support frame 2222 are respectively in sliding connection with the limit rail 2233 of the upper support arm 2231 and the limit rail 2233 of the lower support arm 2232.
In order to ensure the filtering quality and simultaneously facilitate the disassembly, the filtering screen replacement, the scheme adopts double filtering screens, namely a first filtering screen 221 and a second filtering screen 222 at the first ventilation opening 22. The first filter screen 221 is located outside the first ventilation opening 22, and has a higher dust accumulation speed, resulting in a higher disassembling and cleaning frequency, so that the first filter screen is fixed by bolts for convenient disassembling and cleaning. Because the second filter screen 222 is installed inside the adjusting bin 2, the second filter screen 222 is not easy to assemble and disassemble, the fixed frame 223 is introduced in the scheme, the top of the square supporting frame 2222 of the second filter screen 222 is slidably arranged in the limit rail 2233 of the upper support arm 2231, and the bottom of the square supporting frame 2222 of the second filter screen is slidably arranged in the limit rail 2233 of the lower support arm 2232.
Similarly, a third filter screen 231 is installed on the side of the second ventilation opening 23 away from the first ventilation opening 22. Since the second air vent 23 is mainly responsible for exhausting air to the outside, and since the exhausted air has been filtered by the double filter screens of the first filter screen 221 and the second filter screen 222, the second air vent 23 only needs to install the third filter screen 231 for blocking flying insects.
In order to ensure that the first ventilation opening 22 is used for air intake and the second ventilation opening 23 is used for air exhaust, an insulating board 27 is vertically arranged between the second ventilation opening 23 and the thermal insulation bin 21, and one end of the second radiating pipe 544, which is far away from the second cavity 542, is positioned between the insulating board 27 and the second ventilation opening 23. The insulation board 27 keeps apart heat preservation storehouse 21, first vent 22 and second vent 23, and the air-out end of second cooling tube 544 is located between second vent 23 and insulation board 27 in addition, and this makes the hot-blast of second cooling tube 544 discharge to outside through second vent 23, and this has avoided fan 3 to send into humidity control mechanism 5 again with hot-blast to the required energy consumption of semiconductor refrigeration piece 55 during operation has been reduced.
Preferably, the temperature adjusting mechanism 4 is located at an end of the second cavity 542 away from the first cavity 541, and the heating network 43 is installed inside the temperature adjusting mechanism 4. In this embodiment, the second duct 51 and the third duct 42 are respectively located at two ends of the temperature adjusting mechanism 4, which makes the path through which the air from the humidity adjusting mechanism 5 passes longer, thereby ensuring that the air can be sufficiently heated.
The heating net 43 in this embodiment is electrically heated, which is a well-known technology, and thus the present embodiment will not be described in detail.
The heating devices inside the cabinet body 1 are not uniformly distributed, so that the devices with larger heating values can be rapidly cooled to a proper range, the working efficiency of the devices is guaranteed, and the devices are required to be cooled by concentrated wind power. As shown in fig. 8-10, for this purpose, the air outlet mechanism 6 includes a fixed shell 62 and a limiting shell 63, wherein the bottom of the fixed shell 62 is rotatably disposed in the limiting shell 63, the air outlet 60 is located at one end of the fixed shell 62 far away from the limiting shell 63, the air outlet 60 is covered with a first plate 621 and a second plate 622 that are mutually matched, and the first plate 621 and the second plate 622 are both rotatably connected with the fixed shell 62; an exhaust fan 64 is installed at the bottom in the limiting shell 63, and the exhaust fan 64 is arranged corresponding to the air outlet 60. The air outlet mechanism 6 in the scheme is provided with a plurality of air outlet mechanisms 6, wherein the air outlet mechanism 6 close to the heating device can accelerate the rotating speed of the exhaust fan 64 and improve the air outlet quantity. The air outlet mechanism 6 far away from the heating device can adjust the air outlet angle by rotating the first plate 621 and the second plate 622, so that the cooling air can cover the heating device as much as possible. Through the two adjustment modes, the cooling air is not covered in a large range, but intensively cools the heating component, so that the cooling speed of the heating component is increased.
In order to facilitate the first plate body 621, the second plate body 622 to adjust the opening angle, the first plate body 621 installs the first connection plate 623 towards one end of the exhaust fan 64, the second plate body 622 installs the second connection plate 624 towards one end of the exhaust fan 64, the first connection plate 623 is hinged with an arc guide plate 625, the other end of the arc guide plate 625 is hinged with the second connection plate 624, the first connection plate 623 and the second connection plate 624 can rotate along with the movement of the arc guide plate 625 when the arc guide plate 625 moves, at this time, under the driving of the first connection plate 623 and the second connection plate 624, the two ends of the first plate body 621 and the second plate body 622 are both connected with the rotation of the fixed shell 62, so the first plate body 621 and the second plate body 622 can rotate along with the movement of the arc guide plate 625.
In order to control the adjustment angle, this embodiment increases the function of rotating the fixed housing 62, a driving motor 626 is installed in the fixed housing 62, the driving motor 626 is located between the arc-shaped guide plate 625 and the exhaust fan 64, a first connecting rod 627 is hinged to the power output end of the driving motor 626, a second connecting rod 628 is arranged between the first connecting rod 627 and the arc-shaped guide plate 625, one end of the second connecting rod 628 is hinged to the first connecting rod 627, and the other end of the second connecting rod 628 is hinged to the arc-shaped guide plate 625. The driving motor 626 is mounted on the inner side wall of the fixed housing 62 with its axis of the power output end being perpendicular to the axis of the fixed housing 62, and the power output end extending toward the axis of the fixed housing 62, the purpose of which is to locate the power output end below the arc-shaped guide plate 625. The power output end drives the first connecting rod 627 to rotate when rotating, the first connecting rod 627 drives the second connecting rod 628 to displace in the horizontal direction and the vertical direction when rotating, and the second connecting rod 628 drives the arc-shaped guide plate 625 to move when displacing. Since the movement of the second link 628 and the arc-shaped guide plate 625 is limited by the rotation angle of the first link 627, we can control the opening angle of the first plate 621 and the second plate 622 by controlling the rotation of the driving motor 626.
In this solution, the interior of the conditioning bin 2 is coated with an insulating coating or with an insulating material, the purpose of which is to reduce the impact of the electrical components in the switchgear on the components in the conditioning bin 2.
Example 2:
In embodiment 1, since the opening and closing angles of the first plate 621 and the second plate 622 are limited, the air blowing to the heat generating device requiring heat dissipation cannot be accurately adjusted only by controlling the opening angles of the first plate 621 and the second plate 622. Since the bottom of the fixing case 62 is rotatably provided in the limit case 63, we can more accurately adjust the wind direction by driving the fixing case 62 to rotate. As shown in fig. 11-12, for this purpose, a power motor 631 is installed in the limiting shell 63, a protruding structure 620 is disposed on the circumferential direction of the fixing shell 62, a first gear 632 is disposed between the fixing shell 62 and the power motor 631, a second gear 633 is installed at the power output end of the power motor 631, and the second gear 633 and the protruding structure 620 are both engaged with the first gear 632. The power motor 631 drives the second gear 633 to rotate, and the second gear 633 can drive the adjacent first gear 632 to rotate when rotating, and the first gear 632 is meshed with the protruding structure 620 on the fixed shell 62, so that the first gear 632 can drive the fixed shell 62 to rotate in the limiting shell 63 when rotating, and the air outlet direction can also change along with the rotation angle of the fixed shell 62 when rotating, thereby being capable of more accurately conveying air to devices needing cooling.
In order to ensure that the fixed shell 62 rotates stably in the limiting shell 63, a limiting table 634 arranged around the exhaust fan 64 is arranged in the limiting shell 63, a limiting ring groove 6341 is arranged at one end of the limiting table 634 facing the fixed shell 62, the limiting ring groove 6341 is formed by recessing one end of the limiting table 634 facing the first plate 621 towards the bottom of the limiting table 634, and the bottom of the fixed shell 62 is inserted in the limiting ring groove 6341. Further, an annular fixing groove is formed in the outer wall of the fixing shell 62, a limiting protrusion 635 is disposed at the top of the limiting shell 63, and the limiting protrusion 635 is clamped with the annular fixing groove.
Preferably, a temperature sensor 65 and a humidity sensor 66 are mounted on the top of the limiting case 63, and the temperature sensor 65 and the humidity sensor 66 are located at one side of the fixed case 62. The design makes every air-out mechanism 6 can monitor the inside humiture problem of cabinet body 1 at any time, and supplementary procedure draws temperature, humidity distribution image in real time according to the testing result, then gives driving motor 626 and power motor 631 with information feedback according to the distribution image, and then accurate adjustment air-out direction.
Example 3:
In embodiment 2, the bottom of the fixing case 62 is installed in the limit case 63, and the bottom of the fixing case 62 is rotatably connected with the limit ring groove 6341, which ensures that the fixing case 62 is not limited in rotation, but causes a "hysteresis" feeling of the fixing case 62 during rotation due to friction force. This problem is generally solved by injecting lubricating oil into the retainer ring groove 6341. However, when the air outlet mechanism 6 is placed, the axis of the limit groove 6341 is parallel to the horizontal plane, which results in easy outflow of lubricating oil to the outside.
As shown in fig. 13-15, in order to solve this problem, an auxiliary ring 67 is mounted at the bottom of the limit ring groove 6341, a plurality of balls 671 are mounted in the auxiliary ring 67, a positioning groove 672 is formed at one end of the auxiliary ring 67 facing the fixed shell 62, and a partial area of the balls 671 passes through the positioning groove 672 to abut against the bottom of the fixed shell 62.
The above-described scheme utilizes the balls 671 to assist the rotation of the fixed housing 62, reduces the friction force when the fixed housing 62 rotates, and avoids the occurrence of a "hysteresis" feeling when the fixed housing 62 rotates.
In summary, the scheme has the following advantages: firstly, when detecting that the inside air humidity of the cabinet body 1 is great and needs dehumidification, air can enter the humidity adjustment mechanism 5 to dehumidify, the dehumidified air enters the temperature adjustment mechanism 4 to be heated, the heated air enters the cabinet body 1 through the air outlet mechanism 6 to replace the inside moist air of the cabinet body 1, and the inside moist air of the cabinet body 1 can reach the fan 3 through the air inlet 31 and then is sent to the humidity adjustment mechanism 5 by the fan 3 to finish dehumidification operation. The design reduces the introduction amount of outside moist air, and more internal air circulates, so that the moist air can be changed into dry air only by a few wheels of internal air circulation, thereby greatly reducing the working time of the humidity adjusting mechanism 5 and the temperature adjusting mechanism 4 and reducing the energy consumption. Second, the humidity adjusting mechanism 5 is divided into a dehumidifying chamber 53, a first chamber 541 and a second chamber 542, and when the dehumidifying operation is performed, the low-temperature dry air dehumidified by the dehumidifying chamber 53 will first enter the first chamber 541. In the first cavity 541, the low-temperature dry air exchanges heat with the heat dissipation fins 554, so that the low-temperature dry air is preheated before entering the temperature adjusting mechanism 4, energy consumption required for heating the air is reduced, and the heat dissipation fins 554 are also subjected to preliminary cooling, so that the refrigerating efficiency of the refrigerating surface 551 is improved. Thirdly, the air outlet mechanism 6 adjusts the air outlet direction by means of opening and closing of the first plate body 621 and the second plate body 622, so that the refrigerating wind can be used for cooling the heating component, and the electric component with higher heating value can be ensured to work at a proper temperature.
