Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a heat dissipation structure of an energy storage confluence control cabinet. Background Art

[0002] With the development of the energy storage industry, the battery capacity of prefabricated warehouses is getting larger and larger, which leads to the increase of the DC current of the energy storage bus control cabinet in the prefabricated warehouse. At present, the commonly used DC bus isolating switches in prefabricated warehouses are 1250A / 1600A / 2000A / 2500A, with a rated voltage of DC1500V.

[0003] Since the space inside the pre-installed warehouse is relatively closed and the energy of the battery modules is relatively dense, the system generates a lot of heat during operation. In order to ensure the reliable operation of the equipment, in addition to the conventional cooling and ventilation measures in the warehouse, the energy storage confluence control cabinet, as a component that generates relatively large amounts of heat, also needs to take measures to dissipate heat during operation.

[0004] Usually, energy storage convergence control cabinets are maintenance-free and installed against the wall at the back of the cabinet.

[0005] The existing solutions for heating and heat dissipation of energy storage convergence control cabinets on the market are as follows:

[0006] 1. Install the axial flow fan on the front door of the cabinet;

[0007] 2. Open ventilation holes on the front and back doors and edges of the cabinet;

[0008] However, currently, axial fans installed on doors are arranged symmetrically or in the center according to the layout of the door, and the exhaust air may not be directly facing the busbar joint to be cooled, which affects the heat dissipation effect. At the same time, since the places where the DC control cabinets are spliced ​​with cables are all primary strong electricity, if the door is opened for maintenance or to operate other control circuits, the cables on the primary side are directly exposed to the outside, and certain protection is required to prevent human body from direct contact with the live parts. However, if plexiglass or other protection is added in front of the cables and other live parts on the primary side, the primary live parts can indeed be separated from the outside, but this structure blocks the wind from the axial fan, seriously affecting the heat dissipation effect. Utility Model Content

[0009] Therefore, the technical problem to be solved by the utility model is to improve the heat dissipation effect under the premise of ensuring safety. To this end, a heat dissipation structure of an energy storage confluence control cabinet includes:

[0010] A cabinet body, wherein the cabinet body is provided with a receiving cavity for fixing a busbar; the cabinet body comprises a front cabinet door, and the front cabinet door is provided with a first ventilation hole;

[0011] A mounting plate is contained in the accommodating cavity and a fan is fixed on the mounting plate; the mounting plate is located between the busbar and the front cabinet door.

[0012] The mounting plate is detachably connected to the cabinet.

[0013] The mounting plate includes a first fixing portion, a mounting portion, and a second fixing portion. Two ends of the mounting portion are respectively connected to the first fixing portion and the second fixing portion. The fan is fixed to the mounting portion. The first fixing portion and the second fixing portion are connected and fixed to the cabinet.

[0014] The cabinet body comprises a rear side plate, and the rear side plate is provided with a second ventilation hole.

[0015] The fan includes a fan body and a dust cover, the dust cover is located on the side of the mounting plate facing the front cabinet door, the fan body is located on the side of the mounting plate facing the busbar, and the fan body, the dust cover and the mounting plate are connected and fixed.

[0016] Bolts pass through the fan body, the mounting plate and are connected and fixed to the dust cover.

[0017] The cabinet comprises a bottom plate, at least two fixing plates are fixed to the bottom plate, and the fixing plates are provided with cable holes, which are communicated with the accommodating cavity.

[0018] The fixing plate is detachably connected to the bottom plate.

[0019] A partition portion is arranged between two adjacent fixing plates.

[0020] The bottom plate and the fixing plate are both made of stainless steel.

[0021] The technical solution of the utility model has the following advantages:

[0022] 1. The utility model provides a heat dissipation structure of an energy storage busbar control cabinet, which directly installs the fan on the mounting plate to form a heat dissipation and exhaust effect on the busbar connection.

[0023] 2. The utility model provides a heat dissipation structure of an energy storage confluence control cabinet, which has a detachable connection method, and has the effect of adjusting the position of the fan, and can be adjusted according to different connection positions of the busbar.

[0025] 4. The utility model provides a heat dissipation structure of an energy storage convergence control cabinet. The setting of the second ventilation hole forms an effect of cooperating with the first ventilation hole, forming a front-to-back interaction, and further improving the heat dissipation effect.

[0026] 5. The heat dissipation structure of the energy storage convergence control cabinet provided by the utility model adopts a bolt connection method, which is more convenient to install.

[0027] 6. The utility model provides a heat dissipation structure of an energy storage convergence control cabinet. The external cables pass through the cable holes to form a bottom-in effect, and are electrically connected to the busbar.

[0043] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] Example 1

[0045] This embodiment provides a heat dissipation structure of an energy storage confluence control cabinet, as shown in the attached Figure 1-7 As shown, including:

[0046] The cabinet 11 is provided with a receiving cavity 111 for fixing the busbar 12; the connection structure or electrical control structure between the busbar 12 and other components and switches in the cabinet 11 is the prior art, so it is not described in detail in this embodiment. The cabinet 11 includes a front cabinet door 13, and the front cabinet door 13 is used to close the receiving cavity 111 to achieve a closed effect. Here, the front cabinet door 13 and the receiving cavity 111 can be rotatably connected, and a closed effect is achieved by a buckle or a lock. The front cabinet door 13 is provided with a first ventilation hole 131, and there are several first ventilation holes 131, which can be distributed in an array or in a scattered manner. The first ventilation holes 131 are connected to the receiving cavity 111 to form an exchange effect between the air inside the cabinet 11 and the outside air. The size, shape, and number of the first ventilation holes 131 can be adjusted according to actual needs.

[0047] The mounting plate 14 is accommodated in the accommodating chamber 111. The mounting plate 14 is fixed with a fan 15. Here, the fan 15 is used for heat dissipation. When the fan 15 is working, the air inside the cabinet 11 will form an exchange with the external air, which has the effect of heat dissipation and cooling. The mounting plate 14 is located between the busbar 12 and the front cabinet door 13. It should be noted here that the mounting plate 14 is set at a safe distance from the busbar 12, that is, the current generated by the busbar 12 will not arc to the mounting plate 14, thereby ensuring that the mounting plate 14 is not charged. Alternatively, the mounting plate 14 is made of insulating material, which can also have a non-charged effect. By directly installing the fan 15 on the mounting plate 14, a heat dissipation and exhaust effect is formed at the connection of the busbar 12. Even if the front cabinet door 13 is opened, due to the presence of the mounting plate 14, an isolation effect is achieved to prevent the operator from directly contacting the charged body and preventing the occurrence of electric shock.

[0048] Specifically, the mounting plate 14 is detachably connected to the cabinet 11. The detachable connection method has the effect of adjusting the position of the fan 15, and can be adjusted according to different connection positions of the busbar 12. The detachable connection method here can be a bolt connection, a snap-on connection or other connection methods. In addition, the position between the fan 15 and the mounting plate 14 can also be directly adjusted, for example, the fan 15 can slide relative to the mounting plate 14. It should also be noted that a hole is provided on the mounting plate 14 here to allow air to flow, and the size of the hole is adapted to the size of the fan 15. In this embodiment, the fan 15 can be an axial flow fan 15.

[0049] Specifically, as attached Figure 6-7 As shown, the mounting plate 14 includes a first fixing portion 141, a mounting portion 142, and a second fixing portion 143. The two ends of the mounting portion 142 are respectively connected to the first fixing portion 141 and the second fixing portion 143. In this embodiment, the first fixing portion 141 is connected to the upper end of the mounting portion 142 by a vertical bending connection, and the second fixing portion 143 is connected to the lower end of the mounting portion 142 by a vertical bending connection. The fan 15 is fixed to the mounting portion 142. The number of fans 15 can be adjusted according to actual needs, and can be one, two, or even more. The first fixing portion 141 and the second fixing portion 143 are connected and fixed to the cabinet body 11. The first fixing portion 141 is bent above the busbar 12, and the second fixing portion 143 is bent near the side of the front cabinet door 13 to form a connection and fixing effect with the cabinet body 11. The fixing method here can be a bolt connection, a snap connection, etc. The first fixing portion 141 and the second fixing portion 143 are provided to fix the mounting plate 14. The fixing method here can be bolt connection. It should be noted that the mounting plate 14 forms a semi-wrapped structure, so that the busbar 12 is accommodated therein, thereby achieving a better protection effect. Further, in this embodiment, the mounting plate 14 is an integrally formed structure, specifically a bent structure.

[0050] Specifically, as attached Figure 1-4 As shown, the cabinet 11 includes a rear side plate 16, and the rear side plate 16 is provided with a second ventilation hole 161. The setting of the second ventilation hole 161 forms an effect of cooperating with the first ventilation hole 131, forming a front-to-back interaction, and further improving the heat dissipation effect. The number of the second ventilation holes 161 is also several, which can be distributed in an array or scattered. The first ventilation hole 131 and the second ventilation hole 161 can be symmetrical front and back, or can be staggered, and those skilled in the art can adjust according to actual needs.

[0051] Specifically, as attached Figure 6-7 As shown, the fan 15 includes a fan body 151 and a dust cover 152. The dust cover 152 is located on the side of the mounting plate 14 facing the front cabinet door 13, and the fan body 151 is located on the side of the mounting plate 14 facing the busbar 12. The fan body 151, the dust cover 152, and the mounting plate 14 are connected and fixed. The dust cover 152 is not completely closed, but a disc-shaped hollow structure. It should be noted that there will be no cross-current between the fan body 151 and the busbar 12, that is, the arc generated by the busbar 12 will not move to the fan body 151. In addition, it should be noted that the fan 15 can be powered by the cabinet 11 or by the built-in battery of the fan 15.

[0052] Specifically, the bolts pass through the fan body 151, the mounting plate 14 and the dust cover 152 to be connected and fixed. The bolt connection method is more convenient for installation. The number of bolts here can be two, three or four.

[0053] Specifically, as attached Figure 5 As shown, the cabinet 11 includes a bottom plate 17, and at least two fixing plates 18 are fixed to the bottom plate 17. The fixing plates 18 are provided with cable holes 181. The cable holes 181 on a fixing plate 18 can be adjusted according to actual needs, and can be one, two, or more. The cable hole 181 is connected to the accommodating cavity 111. The external cable forms a bottom-in effect through the cable hole 181, and forms an electrical connection with the busbar 12. At the same time, the fixing plates 18 are spliced ​​so that the bottom plate 17 is not an integral structure, which avoids the generation of eddy current phenomenon and solves the heating problem. A gap is provided between two adjacent fixing plates 18.

[0054] Specifically, the fixing plate 18 is detachably connected to the bottom plate 17. Here, the fixing plate 18 and the bottom plate 17 can be connected by bolts or by snap-fit ​​connection. Specifically, the bottom plate 17 is provided with a hole, and the fixing plate 18 is used to close the hole on the bottom plate 17.

[0055] Specifically, a partition portion 182 is provided between two adjacent fixing plates 18. The partition portions 182 cooperate to form a positioning installation effect. During the fixing process, the partition portions 182 of the two adjacent fixing plates 18 fit together. It should be noted here that although the two partition portions 182 fit together, they are not completely 100% fitted together, and there is still a certain gap between the two partition portions 182.

[0056] Specifically, the bottom plate 17 and the fixing plate 18 are both made of stainless steel. The stainless steel material further prevents the generation of eddy current phenomenon.

[0057] Specifically, it should be noted that the present embodiment mainly focuses on the heat dissipation structure. How the entire cabinet performs energy storage and convergence and how it is controlled are irrelevant to the present application and are therefore not described in detail in the present embodiment.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
