Description

[0002] Electrical control cabinets are an integral part of industrial automation, power distribution, and various electrical systems. They house a variety of electrical components and equipment, such as circuit breakers, relays, contactors, inverters, etc. These components generate a lot of heat during operation. If they are not effectively dissipated, the temperature may be too high, which may cause equipment performance degradation, shortened life, and even fire accidents.

[0003] Traditional electrical control cabinets usually use natural cooling or forced air cooling to dissipate heat. However, the effect of natural cooling is limited, especially in high temperature environments. Although forced air cooling can improve heat dissipation efficiency, there is a risk of fan failure, and the introduction of external air may bring dust and moisture, affecting the stability and service life of electrical equipment.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Example 1

[0044] Reference Figure 1-3 , which is the first embodiment of the present invention, and this embodiment provides an internal air circulation and cooling device for an electrical control cabinet, including a control cabinet assembly 100, which includes a control cabinet body 101, a dehumidification port 102 opened on one side of the control cabinet body 101, and an air cooling mechanism arranged on one side of the control cabinet body 101; a heat dissipation and dehumidification assembly 200, which includes a dehumidification shell 201 installed on the outside of the control cabinet body 101, a double-opening mechanism 202 connected to the dehumidification port 102 is opened on the dehumidification shell 201, and a dehumidification mechanism 203 for adsorbing moisture is arranged inside the double-opening mechanism 202; the dehumidification mechanism 203 includes two staggered first dehumidification plates 203a and a second dehumidification plate 203b, and the first dehumidification plate 203a absorbs moisture to a preset range to drive the second dehumidification plate 203b to move and replace the relative position of the first dehumidification plate 203a.

[0045] The sealing design between the control cabinet body 101 and the cabinet door eliminates the heat dissipation holes, which helps prevent external air from entering the cabinet and reduces the possibility of combustion in the event of a fire. The addition of the air cooling mechanism ensures that the air in the control cabinet body 101 can be independently circulated and cooled, reducing the impact of the external ambient temperature and improving the cooling efficiency. The presence of the dehumidification port 102 allows the hot and humid air inside the control cabinet body 101 to be directed to the heat dissipation and dehumidification component 200. The first dehumidification plate 203a and the second dehumidification plate 203b work alternately, using the dehumidification layer 203c to absorb moisture. When a dehumidification plate reaches saturation, it will slide down due to the increase in its own weight. Through the mechanical linkage of the gear 203h, the other dehumidification plate rises to the working position, realizing automatic replacement and maintaining continuous dehumidification capacity. Through the operation of the heat dissipation and dehumidification component 200, condensation of moisture on the inner wall or low-temperature surface of the control cabinet body 101 is avoided, reducing the risk of short circuit, while also maintaining a suitable internal temperature and protecting the operating stability of the electrical equipment.

[0046] The double opening mechanism 202 includes a dehumidification cavity 202a and a drying cavity 202b opened on the dehumidification housing 201. The dehumidification cavity 202a and the drying cavity 202b are vertically distributed. The dehumidification cavity 202a penetrates the dehumidification housing 201 and is arranged horizontally corresponding to the dehumidification port 102. The first dehumidification plate 203a is located above the second dehumidification plate 203b. A slide groove for guiding the first dehumidification plate 203a and the second dehumidification plate 203b is opened inside the dehumidification housing 201. A dehumidification layer 203c for absorbing moisture is fixed on one side of the first dehumidification plate 203a and the second dehumidification plate 203b facing the dehumidification port 102. The first dehumidification plate 203a is fixed with a first tooth plate 203f at both ends, and the second dehumidification plate 203b is fixed with a second tooth plate 203g at both ends. A gear 203h is meshed between the first tooth plate 203f and the second tooth plate 203g. The gear 203h is rotatably set on the inner wall of the dehumidification shell 201, and the first tooth plate 203f drives the second tooth plate 203g to move through the gear 203h.

[0047] In this embodiment, a sealing strip is added between the control cabinet body 101 and the cabinet door, and the heat dissipation holes are eliminated to achieve a sealed setting of the control cabinet body 101, thereby solving the problem of external air entering the cabinet to assist combustion and cause the fire to spread during spontaneous combustion. An air cooling mechanism is adopted to achieve a separate cooling cycle of the air in the control cabinet body 101, thereby reducing the interference of the external ambient temperature and achieving high cooling efficiency.

[0048] By adopting the above-mentioned circulating cooling, there will be a temperature difference between the inside and outside of the control cabinet body 101, which will cause water vapor in the air to condense into water droplets on the cabinet wall or low-temperature surface. Moisture will cause the performance of the insulation material to deteriorate and increase the risk of short circuit.

[0049] To solve the above problems, refer to Figure 1-3By opening a dehumidification port 102 in the upper half of the control cabinet body 101 , the hot air containing moisture generated inside the control cabinet body 101 is gathered, and the heat dissipation and dehumidification component 200 absorbs and filters the moisture to prevent the moisture from condensing in the control cabinet body 101 .

[0050] Specifically, refer to Figure 3-4 When in use, the first dehumidification plate 203a is located at the dehumidification cavity port 202a and is connected to the dehumidification port 102. The dehumidification layer 203c at the first dehumidification plate 203a can automatically adsorb moisture. When the adsorption of the dehumidification layer 203c reaches the preset value range, its own weight will increase by 2-5 times. The increased weight of the dehumidification layer 203c is used as a driving force to drive the first dehumidification plate 203a to slide down. When the first dehumidification plate 203a slides down, the meshing gear 203h is driven to rotate through the first tooth plate 203f. The gear 203h drives the meshing second tooth plate 203g to slide upward, so that the second dehumidification plate 203b replaces the first dehumidification plate 203a to continue the dehumidification operation. Similarly, when the adsorption of the dehumidification layer 203c on the second dehumidification plate 203b reaches the preset value range, the two can be automatically replaced by relying on their own weight, saving time and effort.

[0051] Example 2

[0052] Reference Figure 1-2 and Figure 3-5, which is the second embodiment of the present invention, is different from the previous embodiment in that the blocking assembly 300 includes a plurality of movable blocking mechanisms 301 spaced apart on one side of the dehumidification mechanism 203, and a magnetic block 302 for driving the movable blocking mechanism 301 to operate is disposed inside the dehumidification housing 201, and the magnetic block 302 is used to control whether the movable blocking mechanism 301 is in a ventilating or sealing state. The movable blocking mechanism 301 includes a plurality of vertically spaced blocking plates 301a, which are disposed on a side of the dehumidification mechanism 203 away from the dehumidification layer 203c, and the blocking plates 301a are rotatably connected to the dehumidification housing 201 via a rotating rod 301b. Both ends of the rotating rod 301b are hinged with a connecting rod mechanism 301c, wherein the connecting rod mechanism 301c is formed by a first connecting rod and a second connecting rod being hinged to each other, and the first connecting rod and the second connecting rod are set at an acute angle, and the end of the connecting rod mechanism 301c away from the rotating rod 301b is hinged with a lifting rod 301d, and the lifting rod 301d is slidably set inside the dehumidification housing 201, and the lifting rod 301d pushes the blocking plate 301a to open or close through the connecting rod mechanism 301c. The top of the lifting rod 301d is abutted with a push spring 301e, and a magnet is fixed at the bottom of the lifting rod 301d, and the magnetic block 302 corresponds to the magnet vertically, and the bottom of the magnetic block 302 is fixed on the inner wall of the dehumidification housing 201. A plurality of through holes 203e are provided at the joint between the dehumidification shell 201 and the sealing plate 301a. The through holes 203e are used to shorten the drying time of the dehumidification layer 203c. A flexible magnetic strip 301f is fixed at the joint between the sealing plate 301a and the dehumidification shell 201.

[0053] It can be seen from Example 1 that when the first dehumidification plate 203a is located in the drying cavity 202b, in order to improve the drying efficiency of the dehumidification layer 203c at the first dehumidification plate 203a, the movable sealing mechanism 301 can be opened, thereby increasing the exchange of gas with the outside world and improving the drying speed. The heat generated by the control cabinet body 101 itself during operation can further dry the dehumidification layer 203c.

[0054] Specifically, when the first dehumidification plate 203a slides down into the drying cavity 202b, the magnetic block 302 will generate magnetic force on the magnet, thereby driving the lifting rod 301d to slide down. When the lifting rod 301d slides down, it will push the multiple hinged connecting rod mechanisms 301c, so that the connecting rod mechanisms 301c push the rotating rod 301b to rotate, thereby flipping the multiple blocking plates 301a and opening the through hole 203e, so that the dehumidification layer 203c can come into contact with the external air, thereby accelerating the drying speed.

[0055] When the first dehumidification plate 203a slides up and separates from the magnetic block 302, the lifting rod 301d will slide upward and reset under the pull of the push spring 301e, thereby driving multiple sealing plates 301a to fit with the dehumidification shell 201, realizing the closure of the through hole 203e, and preventing the dehumidification layer 203c from being disturbed by the external environment during dehumidification. The flexible magnetic strip 301f can improve the sealing performance during fitting, and the sealing assembly 300 is also applicable to the second dehumidification plate 203b.

[0056] The heat generated when the control cabinet body 101 is working can be reused to assist the drying process, reducing the overall energy consumption; when the first dehumidification plate 203a moves to the drying cavity opening 202b, the through hole 203e is quickly opened or closed through the action of the connecting rod mechanism 301c and the rotating rod 301b to adapt to different working conditions; the use of flexible magnetic strips 301f enhances the sealing effect between the sealing plate 301a and the dehumidification shell 201, ensuring that it will not be affected by the humidity of the external air during the dehumidification process, thereby improving the dehumidification efficiency and the working stability of the device.

[0057] Example 3

[0058] Reference Figure 3 and Figure 6 , which is the third embodiment of the present invention, and this embodiment further provides an air circulation cooling device inside an electrical control cabinet. A connecting chamber 201a is provided inside the dehumidification housing 201, and a flexible rubber layer 201b is fixed on the inner wall of the connecting chamber 201a. When the first dehumidification plate 203a or the second dehumidification plate 203b rises to a preset height, it will slide into the connecting chamber 201a for sealing. A card interface 203a-1 is provided on the top of the first dehumidification plate 203a and the second dehumidification plate 203b. The card assembly 400 includes a card block 401 located inside the connecting chamber 201a, a card cylinder 402 is movably sleeved on the top of the card block 401, a compression spring is fixed between the card cylinder 402 and the card block 401, a card joint 403 inserted into the card interface 203a-1 is rotatably connected to the bottom of the card block 401, an oblique groove 404 is provided on the outer side of the card joint 403, a sliding rod extending into the oblique groove 404 is provided on the inner wall of the connecting chamber 201a, and a torsion spring is sleeved on the outer side of the card block 401.

[0059] It can be seen from Example 1 that when the dehumidification layer 203c at the first dehumidification plate 203a adsorbs moisture to a preset range, it will slide down. However, if the sliding speed of the first dehumidification plate 203a is slow, the dehumidification cavity 202a will be directly connected to the dehumidification port 102, and the adsorption mechanism of the second dehumidification plate 203b will be lacking, thereby affecting the dehumidification effect.

[0060] In order to solve the above problem, by adding a snap-on assembly 400, when the weight of the first dehumidifier plate 203a does not reach the preset range, the snap-on joint 403 will snap-on with the snap-on interface 203a-1, thereby fixing the first dehumidifier plate 203a, so that the first dehumidifier plate 203a will not slowly drop. When the weight of the moisture adsorbed by the dehumidifier layer 203c on the first dehumidifier plate 203a reaches the preset range, the snap-on block 401 will overcome the elastic force of the compression spring and slide down, and the snap-on block 401 will slide down. When sliding, the card joint 403 is driven to slide down. When the card joint 403 slides down, the slide rod squeezes the inclined groove 404 to make the card joint 403 rotate 3°-8°, thereby separating from the card connection part in the card interface 203a-1, so that the first dehumidification plate 203a can slide down quickly and push the second dehumidification plate 203b to slide into the connecting cavity 201a to replace the first dehumidification plate 203a. The bottom of the card joint 403 is elastic, so it can be easily inserted into the card interface 203a-1 for fixation.
