[0003] Since the electrical components in the power distribution cabinet have certain requirements for the ambient temperature and humidity, when the temperature is too high, too low, or the humidity is too high, the performance of the equipment will be reduced, affecting the use effect.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] Reference Figure 1-Figure 9 The present invention provides an environmentally friendly constant temperature power distribution cabinet, comprising:

[0047] The cabinet 1 defines a receiving cavity 4 inside, the receiving cavity 4 is used to receive electrical components, and the front end is an open end;

[0048] The cabinet door 2 is rotatably fitted at the front end of the cabinet body 1. A control cavity 5 is provided on the inner wall of the cabinet door 2. A driving assembly is provided on the cabinet door 2. The driving end of the driving assembly is connected to the control cavity 5 so that the control cavity 5 can be lifted and lowered in the vertical direction. A guide plate 3 is provided at the outlet end of the control cavity 5. The guide plate 3 faces the electrical components.

[0049] The heat dissipation mechanism includes a heat dissipation cavity arranged on the outer wall of the cabinet door 2, and the heat dissipation cavity is divided into a first heat dissipation zone and a second heat dissipation zone from front to back. The air inlet end of the first heat dissipation zone is connected to the outside, and the air outlet end of the first heat dissipation zone is connected to the control cavity 5. The air inlet end of the second heat dissipation zone is connected to the first heat dissipation zone, and the air outlet end of the second heat dissipation zone is connected to the accommodating cavity 4. When the external environment is high temperature and low humidity, the first heat dissipation zone is used to dissipate heat for electrical components, and when the external environment is high temperature and high humidity, the second heat dissipation zone is used to dissipate heat for electrical components.

[0050] The present invention sets a control chamber 5 on the cabinet door 2 so that the control chamber 5 can be raised and lowered in the vertical direction, and uses a driving component to adjust the position of the control chamber 5 so that the guide plate 3 at the outlet end of the control chamber 5 corresponds to the electrical component. At the same time, a heat dissipation chamber is also set outside the cabinet door 2, and the heat dissipation chamber is divided into a first heat dissipation zone and a second heat dissipation zone in order from front to back. When the external environment is high temperature and low humidity, the first heat dissipation zone is used to dissipate heat and cool the external air, and then communicates with the control chamber 5. The control chamber 5 and the guide plate 3 can be controlled to move to perform point-targeted heat dissipation on the electrical components, which is beneficial to reducing resource waste and improving temperature control effect. When the external environment is high temperature and high humidity, the second heat dissipation zone is directly connected to the inside of the accommodating chamber 4 to achieve heat dissipation of the entire electrical components in the accommodating chamber 4. At the same time, the high-temperature gas is first cooled once through the first heat dissipation zone, and then cooled twice through the second heat dissipation zone, and then the inside of the accommodating chamber 4 is heat-dissipated, thereby improving the heat dissipation effect in the accommodating chamber 4.

[0051] It can be understood that the first heat dissipation area and the second heat dissipation area are used to provide cooling and heat dissipation effects, and water molecules condense while cooling, that is, the humidity of the external air is reduced, so that the heat dissipation gas entering the accommodating chamber 4 is kept in a low-humidity state. In addition, during the operation of the electrical components, heat will inevitably be generated, so the temperature in the cabinet 1 is rarely too low. In addition, the prior art has a method of arranging a heater in the cabinet 1 to increase the temperature inside the cabinet 1. Therefore, when the temperature in the accommodating chamber 4 is too low, the technical solution of the present invention is to arrange a heater (not shown in the figure) in the cabinet 1 to increase the temperature, which is a conventional technical means and will not be repeated.

[0052] Furthermore, it also includes:

[0053] The water absorption layer 6 is fixedly connected in the heat dissipation cavity, and the heat dissipation cavity is divided into a first heat dissipation area and a second heat dissipation area by the water absorption layer 6;

[0054] The heat dissipation component includes a plurality of heat sinks 7 arranged in a heat dissipation cavity. The plurality of heat sinks 7 are distributed in an array on a water absorption layer 6. The heat sinks 7 are in sliding contact with the water absorption layer 6. A control component is arranged in the heat dissipation cavity. The control end of the control component is connected to the plurality of heat sinks 7 so that the heat sinks 7 are rotatably connected to the heat dissipation cavity.

[0055] The water-absorbing layer 6 is made of a polymer water-absorbing material, and the water-absorbing layer 6 is fixed in the heat dissipation cavity, the heat dissipation cavity is separated into a first heat dissipation area and a second heat dissipation area, and the first heat dissipation area and the second heat dissipation area are ventilated and connected, and a plurality of heat dissipation fins 7 are distributed in an array on the water-absorbing layer 6. When external air passes through the heat dissipation cavity, the heat dissipation fins 7 can provide heat dissipation and condensation effects to cool and dehumidify the air.

[0056] In the present technical solution, the heat sink 7 can be rotatably connected in the heat dissipation cavity through a control part, and the heat dissipation cavity is in sliding contact with the water absorption layer 6. During the heat dissipation process, the heat sink 7 can be rotated to absorb and wipe the condensed water vapor on the heat sink 7, thereby improving the heat dissipation effect of the heat dissipation cavity.

[0057] Furthermore, the control element includes:

[0058] The control motor 8 is fixedly connected in the cabinet door 2. The output shaft of the control motor 8 is fixedly connected to the control rod 9 through a coupling. The control rod 9 is transferred in the cabinet door 2 along the length direction of the cabinet door 2.

[0059] The support rod 10 is transferred in the heat dissipation cavity along the vertical direction. A plurality of support rods 10 are arranged at equal intervals along the length direction of the heat dissipation cavity, and a plurality of heat sinks 7 are fixedly connected to any support rod 10. A worm gear 11 is coaxially fixed to the top end of the support rod 10, a worm 12 is meshed with one side of the worm gear 11, and the worm 12 is coaxially fixed to the control rod 9.

[0060] The control motor 8 is used to drive the control rod 9 to rotate. At the same time, the worm 12 coaxially fixed to the control rod 9 rotates. The worm 12 drives the worm wheel 11 to rotate. The worm wheel 11 realizes the rotation of the support rod 10, so that the support rod 10 drives a plurality of heat sinks 7 to rotate. By fixing the water absorption layer 6 in the heat dissipation cavity, the heat sink 7 directly slides in contact with the water absorption layer 6 during rotation, thereby completing the cleaning of condensed water vapor on the surface of the heat sink 7 during the heat dissipation process, thereby ensuring the heat dissipation effect.

[0061] Specifically, since a plurality of heat sinks 7 are evenly spaced on the support rod 10 , the surface of the heat sink 7 is wiped by filling the gap between two adjacent heat sinks 7 with the water absorbing layer 6 .

[0062] In one embodiment of the present technical solution, the heat sink 7 is a circular structure, the support rod 10 is fixedly connected to the axis of the heat sink 7, and a notch is opened on one side of the heat sink 7, which can form a guide channel in the first heat sink area or the second heat sink area, so as to facilitate the guided flow of air. During the flow process, the circular structure of the heat sink 7 forms a bulge along the water absorption layer 6, so that water vapor condenses on the surface of the heat sink 7. In combination with the support rod 10 to rotate the heat sink 7, the water absorption layer 6 wipes the heat sink 7, thereby achieving efficient cooling and dehumidification of the external air.

[0063] Furthermore, it also includes:

[0064] The base 13 is fixedly connected to the bottom of the heat dissipation cavity, and a fan zone is defined between the bottom surface of the base 13 and the heat dissipation cavity;

[0065] The fan group is arranged in the fan interval, including at least one first fan 14 arranged below the first heat dissipation zone, and at least one second fan 15 arranged below the second heat dissipation zone. The air inlet of the first fan 14 is connected with the first heat dissipation zone through a first air inlet pipe 16, and the first air inlet pipe 16 passes through the base 13 in the vertical direction. The air outlet of the first fan 14 is connected with a first air outlet pipe 17, and one side of the first air outlet pipe 17 is connected with the control chamber 5 through a flexible tube 18. The air inlet of the second fan 15 is connected with the second heat dissipation zone through a second air inlet pipe 19, and the second air inlet pipe 19 passes through the base 13 in the vertical direction. A through hole is opened on the inner wall of the cabinet door 2, and the through hole is connected with the air outlet of the second fan 15.

[0066] In the present technical solution, since the first heat dissipation zone and the second heat dissipation zone are sequentially arranged in the heat dissipation cavity along the direction from front to back, and the heat dissipation cavity is arranged on the outer wall of the cabinet door 2, the external air first enters the first heat dissipation zone, and the first heat dissipation zone and the control cavity 5 are connected by the first fan 14. When the external environment is high temperature and low humidity, the first fan 14 is started to pass high temperature and low humidity air from the first heat dissipation zone to the first air inlet pipe 16, and the heat sink 7 and the side of the water absorption layer 6 in the first heat dissipation zone reduce the air temperature, and then the air is passed into the control cavity 5 through the first air outlet pipe 17 and the flexible tube 18. The electrical components are targeted for cooling by moving the control cavity 5 up and down, thereby saving resource consumption.

[0067] When the external environment is of high temperature and high humidity, the air from the first heat dissipation area is sucked into the second heat dissipation area through the second fan 15, so that the air can fully pass through the cooling and dehumidifying effects of the heat sink 7 and the water absorption layer 6, and then pass into the accommodating cavity 4 through the second air outlet pipe in a covering manner, thereby achieving cooling and heat dissipation of the entire electrical components.

[0068] Since the external environment is cooled and humidified appropriately, resources are effectively saved, and the temperature and humidity in the accommodation chamber 4 are adjusted in an environmentally friendly constant temperature manner to ensure the normal operation of the electrical components.

[0069] Furthermore, a heat dissipation shell 20 is fixedly connected to the outer wall of the cabinet door 2, and a heat dissipation cavity is defined in the heat dissipation shell 20. The heat dissipation shell 20 has an opening on the side away from the cabinet door 2, a grille 21 is fixedly connected in the opening, and a filter is arranged between the opening and the first heat dissipation area.

[0070] The external air is filtered and purified by the grille 21 and the filter element to prevent impurities from entering the heat dissipation cavity, thereby increasing the service life of the heat dissipation fins 7 and the water absorption layer 6.

[0071] Further, the filter element comprises:

[0072] A pair of support plates 22 are respectively fixedly connected to opposite sides of the inner wall of the heat dissipation housing 20. Slots are provided on the mutually adjacent sides of the pair of support plates 22. A plug-in plate 23 is inserted into the slot, and the plug-in plate 23 is erected between the pair of support plates 22. A through groove is provided at the center of the plug-in plate 23. A filter screen 24 is fixedly connected in the through groove. The projection of the filter screen 24 along the horizontal direction covers the opening. A bayonet is provided at the top of the heat dissipation housing 20. A card block 25 is clamped in the bayonet. The bottom end of the card block 25 is fixedly connected to the top of the plug-in plate 23.

[0073] The filter 24 is used to cover the opening on the heat dissipation housing 20 to filter the external air. The filter 24 is fixed by the plug plate 23, and the plug plate 23 is plugged into the slot. When replacing the filter 24, only the card block 25 needs to be pulled out, and the card port will be directly opened, and the filter 24 can be replaced, thereby improving work efficiency.

[0074] Furthermore, a control seat 26 is slidably connected to the inner wall of the cabinet door 2 in the vertical direction, and a control cavity 5 is opened on the side of the control seat 26 close to the electrical components. A rotating part is arranged on the control seat 26, and the rotating end of the rotating part is connected to the guide plate 3. The guide plate 3 is rotatably connected to the control seat 26, and the guide plate 3 can block the port of the control seat 26.

[0075] A control chamber 5 is defined by setting a control seat 26 on the inner wall of the cabinet door 2, and the guide plate 3 is driven to rotate by a rotating member set on the control seat 26, so that the air entering the control chamber 5 through the first heat dissipation area can be transported to the corresponding electrical components in a directional manner.

[0076] Furthermore, the rotating member comprises:

[0077] A pair of servo motors 27 are fixedly connected to two sides of the control base 26, and the output shafts of the servo motors 27 are fixedly connected to the adjacent sides of the guide plate 3;

[0078] A plurality of guide holes are provided at the center of the guide plate 3 , and the guide holes are distributed in an array. Both ends of the guide plate 3 are arc-shaped structures, and the arc-shaped ends of the guide plate 3 are in sliding contact with the control seat 26 .

[0079] The guide plate 3 is rotated by the servo motor 27, and the guide holes on the guide plate 3 realize the communication between the inside and outside of the control chamber 5, so that the cooled and dehumidified air is passed along the guide plate 3 to the electrical components to achieve targeted heat dissipation.

[0080] Furthermore, the driving component includes:

[0081] A pair of fixed seats 28 are fixedly connected to both sides of the inner wall of the cabinet door 2, respectively. The sides of the fixed seats 28 close to each other are provided with sliding grooves, and a slider 29 is slidably connected in the sliding grooves. The slider 29 is fixedly connected to the control seat 26.

[0082] The driving motor 30 is fixedly connected to the inner wall of the cabinet door 2 . The output shaft of the driving motor 30 is fixedly connected to a screw rod 31 . The screw rod 31 is transferred into the slide groove, and the slider 29 is threadedly sleeved on the screw rod 31 .

[0083] The driving motor 30 is used to rotate the screw rod 31 , and the rotation of the screw rod 31 causes the slider 29 to slide along the slide groove, thereby driving the control seat 26 to slide axially along the fixed seat 28 , thereby realizing the lifting and lowering drive of the control seat 26 .

[0084] Furthermore, it also includes:

[0085] The controller 32 is installed on one side of the outer wall of the cabinet 1;

[0086] There are several temperature and humidity sensors 33 , and a connecting plate 34 is fixedly connected to the opposite side of the inner wall of the cabinet 1 along the vertical direction. Several temperature and humidity sensors 33 are fixedly connected to the connecting plate 34 at equal intervals along the vertical direction. The temperature and humidity sensors 33 are communicatively connected to the controller 32 .

[0087] A plurality of temperature and humidity sensors 33 are used to detect the environment in the accommodating chamber 4. At the same time, the installation position of the temperature and humidity sensors 33 is limited by the connecting plate 34, so that the temperature and humidity sensors 33 form a detection interval from top to bottom. When a corresponding electrical component in a certain place in the detection interval produces high temperature and high humidity, the controller 32 communicates with the plurality of temperature and humidity sensors 33, thereby directly obtaining the specific position information of the corresponding area. The controller 32 is communicated with the drive motor 30 and the servo motor 27 through the signal transceiver 35. After the controller 32 converts the position information into an electrical signal, it directly controls the screw 31 to rotate a corresponding number of circles, so that the control seat 26 moves to the corresponding position. At the same time, the servo motor 27 rotates to turn the guide plate 3 toward the electrical component located at this position for targeted heat dissipation. The control principle of the controller 32 receiving the temperature and humidity sensor 33 signal and transmitting the driving electrical signal to the drive motor 30 and the servo motor 27 is a prior art and will not be described in detail.

[0088] The working principle of an environmentally friendly constant temperature power distribution cabinet of the present invention is as follows:

[0089] When the external environment is high temperature and low humidity, and the temperature and humidity sensor 33 detects that the electrical components in a certain area generate high temperature, the drive motor 30 is started to rotate the screw 31, and the screw 31 slides the slider 29 along the fixed seat 28, and the control seat 26 is lifted and lowered along the fixed seat 28, so that the control seat 26 moves to the corresponding position. If the high temperature area is outside the moving range of the fixed seat 28, the servo motor 27 is used to rotate the guide plate 3 so that the guide plate 3 faces the electrical components. After starting the first fan 14, the first fan 14 draws the air in the first heat dissipation area. After the air in the first heat dissipation area is cooled and dehumidified by a plurality of heat sinks 7 and a water absorption layer 6, it is passed into the control cavity 5 through the flexible tube 18, and finally the corresponding electrical components are subjected to targeted heat dissipation.

[0090] When the external environment is of high temperature and high humidity, the overall environment in the accommodating chamber 4 is also affected. At this time, the temperature and humidity sensor 33 receives the environmental signal in the accommodating chamber 4, and the second fan 15 is started. The air is sucked from the second heat dissipation zone by the second air inlet pipe. The air first passes through the first heat dissipation zone and then the water absorption layer 6. Before entering the second heat dissipation zone, the air is fully cooled and dehumidified by the heat sink 7. Then, the second fan 15 passes the air directly into the accommodating chamber 4 to achieve cooling and dehumidification inside the accommodating chamber 4.
