Description

Technical Field

[0001] This invention relates to the field of energy storage air conditioning structure technology, specifically to an electrically controlled multi-stage rotating cabinet air conditioner. Background Technology

[0002] An energy storage air conditioner is a device that regulates the temperature, relative humidity, and airflow speed within an energy storage battery cabinet. It differs significantly from a regular air conditioner in structure, the objects it serves, and the environment in which it operates. Conventional air conditioners typically incorporate internal sliding mechanisms to allow the electrical control box (03) to be pulled out for maintenance. However, for energy storage air conditioners, this design suffers from drawbacks such as limited maintenance space and poor heat dissipation.

[0003] Specifically, such as Figure 1 As shown, a conventional energy storage air conditioner is typically installed adjacent to wall 06. The energy storage air conditioner specifically includes a cabinet 01, with a cabinet door 02 rotatably connected to the cabinet 01. An electrical control box 03 is slidably connected inside the cabinet 01. A recess 04 is provided on one side of the electrical control box 03, and electronic components 05 are installed within the recess 04. When maintenance of the electrical control box 03 is required, it can be pulled out of the cabinet 01. However, regardless of whether the recess 04 faces the cabinet door 02 or the cavity 06, the operable space is limited. For example… Figure 1 The maintenance space is limited by wall 06, which makes maintenance inconvenient.

[0004] Furthermore, in order to overcome the above-mentioned deficiencies, those skilled in the art typically employ the following improvements: such as Figure 2 and Figure 3 As shown, the groove 04 is positioned facing the inside of the cavity 06, and the electrical control box 03 is rotatably connected to the cabinet 01. When maintenance of the electrical control box 03 is required, the electrical control box 03 is rotated to... Figure 3 In this position, the maintenance space is not limited by cavity 06 or cabinet door 02, making it convenient for staff to carry out maintenance.

[0005] Obviously, the above Figures 2 to 3 However, the structure in the middle makes the heat dissipation of electronic component 05 poor. Because maintenance is required, the side of electronic component 05 facing the groove opening of groove 04 cannot be equipped with heat dissipation structure 07. That is, heat dissipation structure 07 can only be embedded in the bottom of groove 04, resulting in unsatisfactory heat dissipation of electronic component 05. Figure 4 As shown, if the electrical control box 03 is directly flipped, although the heat dissipation effect can be improved, when it is maintained, the electrical control box 03 can only be rotated inward. At this time, the electrical control box 03 is screwed into the cabinet 01, which is not conducive to the maintenance of the electrical control box 03 by the staff.

[0006] In conclusion, conventional energy storage air conditioners cannot simultaneously solve the problems of limited maintenance space and poor heat dissipation. Summary of the Invention

Figure 11 This is a schematic diagram of the fourth partial structure of the electrically controlled multi-stage rotary cabinet air conditioner provided in an embodiment of the present invention. Figure 12 This is a schematic diagram of the fifth partial structure of an electronically controlled multi-stage rotating cabinet air conditioner provided in an embodiment of the present invention.

[0052] The electrically controlled multi-stage rotating cabinet air conditioner provided in this embodiment can be installed in an energy storage battery cabinet as an energy storage air conditioner to regulate temperature and humidity. It is also suitable for other computer room scenarios with limited installation space. In this embodiment, by optimizing the structure of the electrically controlled multi-stage rotating cabinet air conditioner, it can be installed in various narrow spaces while ensuring that its electrical control part is easy to maintain and has good heat dissipation.

[0053] like Figures 5 to 8 As shown, the electronically controlled multi-stage rotating cabinet air conditioner includes a cabinet 10, which has a mounting slot 11. A first maintenance station 12 and a second maintenance station 13 are provided within the slot of the mounting slot 11; wherein, as... Figure 7 As shown, the first maintenance station 12 and the second maintenance station 13 are arranged sequentially along the width of the mounting groove 11, facilitating the unfolding of the subsequent electrical control components at the opening of the mounting groove 11 for easy maintenance by personnel. The aforementioned electrical control components include a first electrical control unit 20, a second electrical control unit 30, and a heat dissipation unit 40 sequentially arranged on the groove wall of the mounting groove 11. The first electrical control unit 20 includes a first maintenance surface, and the second electrical control unit 30 includes a second maintenance surface, with the first and second maintenance surfaces facing each other; wherein, as... Figure 12 As shown, a first electronic component 53 is provided on the first inspection surface, and a second electronic component 54 is provided on the second inspection surface.

[0054] Among them, such as Figures 5 to 8 As shown, the first electrical control unit 20 is rotatably connected to the wall of the mounting groove 11 and can rotate to the first maintenance station 12 so that the first maintenance surface faces the outside of the mounting groove 11; the second electrical control unit 30 is rotatably connected to the first electrical control unit 20 and can rotate to the second maintenance station 13 so that the second maintenance surface faces the outside of the mounting groove 11. Specifically, as Figure 5 and Figure 8 As shown, when in operation, the first electronic control unit 20, the second electronic control unit 30, and the heat dissipation unit 40 are sequentially mounted on the wall of the mounting slot 11. At this time, the heat dissipation unit 40 is located within the mounting slot 11 and is not obstructed by the electronic control units. Therefore, it can utilize the internal airflow within the cabinet 10 to remove heat from the heat dissipation unit 40, resulting in excellent heat dissipation. When maintenance is required, such as... Figure 6 As shown, the first electronic control unit 20 can be rotated along the first direction (clockwise in this embodiment) to rotate the first inspection surface to the first inspection station 12; then, the second electronic control unit 30 can be rotated along the second direction (counterclockwise in this embodiment) to unfold the second inspection surface to the second inspection station 13. Since the first inspection station 12 and the second inspection station 13 are located at the opening of the mounting slot 11, the operator can perform frontal maintenance on the electronic components of the first electronic control unit 20 and the second electronic control unit 30 from the opening of the mounting slot 11, providing ample maintenance space. Therefore, this multi-stage rotating cabinet air conditioner has the characteristics of large maintenance space and excellent heat dissipation. It should be added that the heat dissipation unit 40 is essentially placed outside the electronic control unit, which can reduce the thickness of the electronic control unit, avoid the blockage of return airflow when the electronic control unit has a large area and volume, and avoid the situation where the electronic components fail due to heat caused by high temperature inside the electronic control unit; at the same time, as Figure 8As shown, the heat dissipation unit 40 is located between the second electronic control unit 40 and the evaporator 80. At this time, the space occupied by the heat dissipation unit 40 is relatively large, which allows it to fully contact the return airflow, further improving the heat dissipation effect of the heat dissipation unit 40.

[0055] In this embodiment, as Figure 12 As shown, the first electronic control unit 20 is provided with a first electronic control groove 21, and the second electronic control unit 30 is provided with a second electronic control groove 31. The first electronic control groove 21 and the second electronic control groove 31 are arranged opposite to each other. A first inspection surface is provided on the wall surface of the first electronic control groove 21 facing the second electronic control groove 31, and a second inspection surface is provided on the wall surface of the second electronic control groove 31 facing the first electronic control groove 21. That is, the first inspection surface is provided at the bottom of the first electronic control groove 21, and the second inspection surface is provided at the bottom of the second electronic control groove 31. A first electronic component 53 can be installed in the first electronic control groove 21, and a second electronic component 54 can be installed in the second electronic control groove 31. It should be noted that the first electronic control unit 20 and the second electronic control unit 30 are formed by sheet metal bending. In other optional embodiments, the first electronic control unit 20 and the second electronic control unit 30 can also be formed by plastic or other materials, and the first electronic control unit 20 and the second electronic control unit 30 can also be plate-shaped structures.

[0056] Furthermore, such as Figures 9 to 12 As shown, when the first inspection surface and the second inspection surface are arranged opposite each other, the first electrical control slot 21 and the second electrical control slot 31 are joined together on the second inspection surface to form an installation cavity; the second electronic component 54 in the second electrical control unit 30 is disposed in the installation cavity. The second electronic component 54 can be a frequency converter, etc., while the frequency converter's heat sink, as a heat dissipation unit 40, is disposed outside the installation cavity, which helps to reduce the size of the second electrical control unit 30 and thus reduce the amount of material used. The second electrical control unit 30 has a heat dissipation clearance opening 32 corresponding to the position of the heat dissipation unit 40. Simultaneously, the plane where the heat sink is located is parallel to the air intake direction of the heat absorption and cooling unit 80, which can improve the heat exchange efficiency of the heat sink, further benefit the heat dissipation of the frequency converter, and reduce the impact on the airflow of the cabinet 10.

[0057] Furthermore, the size of the first electrical control slot 21 is larger than the size of the second electrical control slot 31, and the first electronic component 53 in the first electrical control unit 20 is disposed outside the mounting cavity. This arrangement results in a smaller overall thickness of the second electrical control unit 30 when it covers the first electrical control unit 20, and distributes heat between the first access door and the second access surface, facilitating internal airflow to remove heat from the electrical control unit. Simultaneously, because the size of the first electrical control slot 21 is larger than the second electrical control slot 31, it is easier for personnel to perform wiring operations on the first electronic component 53. In other optional embodiments, the size of the first electrical control slot 21 can be equal to that of the second electrical control slot 31.

[0058] Furthermore, such as Figure 5 , Figure 6 and Figure 11 As shown, the first electrical control unit 20 includes a first end 23 and a second end 24 disposed outside the first electrical control groove 21, with the first electrical control groove 21 located between the first end 23 and the second end 24. A first rotating unit 51 is mounted on the edge of the groove opening of the mounting groove 11, and the first end 23 is rotatably connected to the mounting groove 11 via the first rotating unit 51. A second rotating unit 52 is mounted on the second end 24, and the second electrical control unit 30 is rotatably connected to the first electrical control unit 20 via the second rotating unit 52. The rotating unit is a hinge. Specifically, the first electrical control unit 20 can rotate to the first maintenance station 12 via the first rotating unit 51, and the second electrical control unit 30 can rotate to the second maintenance station 13 via the second rotating unit 52. This structure has the advantage of occupying little space. In other alternative embodiments, the first maintenance station 12 can be located on the right side of the opening of the mounting groove 11, and the second maintenance station 13 can be located on the left side of the opening of the mounting groove 11. An extension member is also provided between the first electronic control unit 20 and the first rotating unit 51, so that the first electronic control unit 20 can be rotated from the left wall of the mounting groove 11 to the first maintenance station 12 via the first rotating unit 51. At this time, the second electronic control unit 30 can be rotated from the first maintenance station 12 to the second maintenance station 13. In this embodiment, the first rotating unit 51 and the second rotating unit 52 can both be located on the first end 23.

[0059] Furthermore, such as Figure 7 and Figure 12 As shown, a rotating shaft is provided between the first electrical control unit 20 and the mounting slot 11, allowing the first electrical control unit 20 to rotate around the rotating shaft. A first cable inlet hole 22 is provided on the wall of the first electrical control slot 21, and the opening direction of the first cable inlet hole 22 is parallel to the extension direction of the rotating shaft. A second cable inlet hole 14 is provided on the cabinet 10 corresponding to the position of the first cable inlet hole 22. With the above arrangement, the first electrical control unit 20 will not be interfered with by the cable when rotating, and the cable will not be pulled and rubbed against the metal parts, thus improving the maintenance convenience of the multi-stage rotating cabinet air conditioner.

[0060] Furthermore, a door 60 is rotatably connected to the mounting slot 11 at the opening of the cabinet 10. The door 60 and the first electrical control unit 20 are mounted on the same side wall of the mounting slot 11. This arrangement ensures that the rotation direction of the door 60 is the same as the opening direction of the first electrical control unit 20, both clockwise. This facilitates the operation of unfolding the electrical control unit and improves the maintenance convenience of the multi-stage rotating cabinet air conditioner. In other optional embodiments, the first electrical control unit 20 and the first rotating unit 51 can be mounted on other side walls of the mounting slot 11.

[0061] Furthermore, such as Figure 8As shown, a heat-absorbing and cooling unit 80 is installed in the mounting slot 11, a return air vent 61 is provided on the door 60, and an air supply vent 15 is provided on the wall of the mounting slot 11. The heat-absorbing and cooling unit 80 is located between the return air vent 61 and the air supply vent 15, and the first electrical control unit 20 is located between the return air vent 61 and the heat-absorbing and cooling unit 80. That is, indoor return air can enter the cabinet 10 through the return air vent 61, carry away the heat from the electrical control unit, and then pass through the heat-absorbing and cooling units 80 such as the copper tube finned evaporator and the microchannel evaporator to complete the cooling. After cooling, it is then transported to the outside of the cabinet 10 through the air supply vent 15 by the evaporator fan 94.

[0062] Meanwhile, a condenser 91 and a compressor 92 are also provided at the bottom of the mounting slot 11. A partition is provided in the mounting slot 11. A heat absorption cooling unit 80 and an evaporator fan 94 are installed above the partition, and a condenser 91 and a compressor 92 are installed below the partition. The condenser 91 is connected to the heat absorption cooling unit 80 through the compressor 92 to achieve circulating cooling. Correspondingly, an outdoor air inlet and an outdoor air outlet are provided on the mounting slot 11 to cool the condenser tube 91. A condenser fan 93 is provided at the outdoor air outlet to promote circulation. In this embodiment, multiple condenser fans 93 are provided, and the air outlets are not on the same horizontal plane. The air outlet of the condenser fan farther from the outdoor air outlet is higher than the air outlet of the condenser fan closer to the outdoor air outlet. This can reduce mutual airflow interference between multiple fans, increase the overall airflow, and at the same speed, help to increase the heat exchange of the condenser 91 and achieve a more energy-saving effect.

[0063] Based on the above implementation, an operation panel 70 is installed on the side of the door 60 away from the first electronic control unit 20. Since the return air vent 61 in this embodiment is located on the door 60, the indoor return air will enter the cabinet 10 through the door 60 and blow from the air supply vents 15 on both sides of the cabinet 10 toward the heat dissipation target (in this embodiment, the heat dissipation target is the energy storage battery). In this case, when the staff operates the electronically controlled multi-stage rotating cabinet air conditioner through the operation panel 70, on the one hand, the operation panel 70 is set adjacent to the electronic control unit, which reduces the wiring length and the generation of internal heat. On the other hand, the operation panel 70 is on the same side as the return air vent 61 and on the opposite side of the air supply vent 15 and the outdoor air inlet and outlet, which can avoid the airflow from causing discomfort to the staff. This is convenient for the staff to maintain and also helps with heat dissipation.

[0064] In summary, the electronically controlled multi-stage rotating cabinet air conditioner of this embodiment has the advantages of large maintenance space and excellent heat dissipation, as well as other advantages such as small size, compact structure, and easy maintenance.

[0065] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
