TECHNICAL FIELD

[0001] The present application relates to the technical field of rectifier cabinet, and particularly relates to a rectifier cabinet cooling system and a rectifier cabinet applying the same. BACKGROUND

[0002] The rectifier cabinet is a power device for converting alternating current into direct current. Since there are many electrical components in the rectifier cabinet that generate heat, a corresponding cooling system is configured inside the rectifier cabinet to dissipate heat and maintain normal operation of the rectifier cabinet.

[0003] In the related art, the cooling system includes two water pumps that are used as backups and two groups of heat sink assemblies. One water pump corresponds to one heat sink assembly, so that the water pump pumps cooling water into the heat sink, and the cooling water flows in the heat sink. In addition, during use of the rectifier cabinet, the heat sink assemblies need to be disassembled and cleaned so that the heat sink assemblies have good heat dissipation function.

[0004] However, in the above-mentioned rectifier cabinet, when one of the heat sink assemblies is disassembled, the cooling water flowing in the heat sink assembly may splash onto the water pump corresponding to the other heat sink assembly, which may damage the circuit inside the water pump and affect the heat dissipation of the rectifier cabinet and the use of the rectifier cabinet. CONTENT OF THE INVENTION

[0005] The present application provides a rectifier cabinet cooling system and a rectifier cabinet. When one of the heat sink assemblies is disassembled and cleaned, the cooling water in the heat sink assembly can be prevented from splashing onto the water pump corresponding to the other heat sink assembly, so that the water pump can operate normally, and thus the rectifier cabinet cooling system and the rectifier cabinet can operate normally. The specific technical solutions are as follows:

[0006] On one hand, the present application provides a rectifier cabinet cooling system arranged inside a rectifier cabinet. The rectifier cabinet cooling system provided by the present application includes two groups of heat sink assemblies and two water pumps, one heat sink assembly corresponding to one water pump. When one of the two groups of heat sink assemblies is disassembled and cleaned, a waterproof sleeve is sleeved on the water pump corresponding to the other heat sink assembly, and the bottom of the waterproof sleeve forms an opening.

[0007] As an optional implementation, the water pump includes a base and a water pump body connected to the lower end of the base, and the size of the base in the horizontal direction is greater than the size of the water pump body in the horizontal direction. The waterproof sleeve includes a first sleeving part and a second sleeving part, the second sleeving part is connected to the lower end of the first sleeving part, the first sleeving part cooperates with the base, and the second sleeving part cooperates with the water pump body. The outer diameter of the second sleeving part is smaller than the outer diameter of the first sleeving part, and the bottom end of the second sleeving part forms an opening.

[0008] As an optional implementation, the second sleeve part is detachably connected with the first sleeve part.

[0009] As an optional implementation, a buckle is arranged on one of the first sleeve part and the second sleeve part, and a clamping groove is arranged on the other one; the buckle is clamped and connected with the clamping groove, so as to detachably connect the first sleeve part with the second sleeve part.

[0010] As an optional implementation, the buckle and the clamping groove are both multiple, and one buckle corresponds to one clamping groove.

[0011] As an optional implementation, the first sleeve part and the second sleeve part are both elastic structures.

[0012] As an optional implementation, a waterproof layer is arranged on the outer side of the first sleeve part and the second sleeve part.

[0013] As an optional implementation, the wall thickness of the first sleeve part and the second sleeve part is greater than the thickness of the waterproof layer.

[0014] As an optional implementation, the waterproof sleeve is an integral structure.

[0015] On the other hand, the application provides a rectifier cabinet, which comprises a cabinet door, a cabinet body and the rectifier cabinet cooling system; the cabinet door is installed on the cabinet body and forms an installation cavity together with the cabinet body, and the rectifier cabinet cooling system is installed in the installation cavity.

[0016] The rectifier cabinet cooling system and the rectifier cabinet provided by the application can avoid the cooling water in the heat dissipation fin assembly from splashing on the other water pump to a certain extent when one of the two groups of heat dissipation fin assemblies is disassembled, because the rectifier cabinet cooling system needs to be operated all the time during the operation of the rectifier cabinet, that is, the other water pump is also in operation, and if the cooling water splashes on the water pump, the circuit in the water pump may be short-circuited, which affects the cooling performance of the rectifier cabinet cooling system and the use of the rectifier cabinet. Therefore, in the rectifier cabinet cooling system provided by the application, the circuit in the water pump can be short-circuited to a certain extent by arranging the waterproof sleeve, so that the water pump can operate normally, and the cooling performance of the rectifier cabinet cooling system and the normal use of the rectifier cabinet are maintained.

[0026] The technical solutions in the present application will be described in detail below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent: A exists alone, A and B exist together, and B exists alone, and in addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0027] Hereinafter, the terms "first", "second" are only used for description purposes, and cannot be understood as implying or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0028] The rectifier cabinet is a kind of power equipment for converting alternating current into direct current, and since there are many electrical components in the rectifier cabinet that will emit heat, in order to dissipate heat and maintain the normal operation of the rectifier cabinet, a corresponding cooling system is configured inside the rectifier cabinet. In the related art, the cooling system includes two water pumps that are used as backup for each other, and two groups of heat sink assemblies, one water pump corresponding to one heat sink assembly, so as to pump cooling water into the heat sink through the water pump, and the cooling water flows in the heat sink, in addition, during the use of the rectifier cabinet, the heat sink assemblies need to be disassembled and cleaned so that the heat sink assemblies have good heat dissipation function. However, in the above-mentioned rectifier cabinet, when one of the two groups of heat sink assemblies is disassembled, the cooling water flowing inside the heat sink assembly may splash onto the water pump corresponding to the other group of heat sink assemblies, thereby possibly damaging the circuit inside the water pump and affecting the heat dissipation of the rectifier cabinet and the use of the rectifier cabinet.

[0029] Therefore, the embodiment of the present application provides a rectifier cabinet cooling system and a rectifier cabinet, which can prevent the cooling water from splashing onto the water pump corresponding to the other group of heat sink assemblies to a certain extent when one of the two groups of heat sink assemblies is disassembled, so that the rectifier cabinet can be normally cooled and normally used.

[0030] The embodiment of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please refer to Figures 1 to 3 , Figure 1 The structure diagram of the rectifier cabinet provided by the embodiment of the present application, Figure 2 The structure diagram of the local structure of the rectifier cabinet provided by the embodiment of the present application, Figure 3 is Figure 2 The enlarged schematic diagram of the local structure at A in FIG. 1. As shown in the figure, the embodiment provides a rectifier cabinet cooling system arranged inside the rectifier cabinet, which includes two groups of heat sink assemblies 1 and two water pumps 2, one heat sink assembly 1 corresponding to one water pump 2; wherein when one of the two groups of heat sink assemblies 1 is disassembled and cleaned, a waterproof sleeve 3 is sleeved on the water pump 2 corresponding to the other group, and the bottom of the waterproof sleeve 3 forms an open top.

[0032] When one of the two sets of heat sink assemblies 1 is disassembled for cleaning, the waterproof sleeve 3 is sleeved on the water pump 2 corresponding to the other set of heat sink assemblies 1, so that when one of the two sets of heat sink assemblies 1 is disassembled, the cooling water in the heat sink assembly 1 can be prevented from splashing onto the other water pump 2 to a certain extent. Since the rectifier cabinet cooling system needs to be running during the operation of the rectifier cabinet, that is, the other water pump 2 is also running, if the cooling water splashes onto it, it may cause a short circuit of the circuit in the water pump 2, affecting the cooling performance of the rectifier cabinet cooling system and the use of the rectifier cabinet. Therefore, in the rectifier cabinet cooling system provided by the embodiment, the waterproof sleeve 3 can prevent the circuit in the water pump 2 from short-circuiting to a certain extent, so that the water pump 2 can operate normally, and the cooling performance of the rectifier cabinet cooling system and the normal use of the rectifier cabinet are maintained.

[0033] Please combine Figure 4 , Figure 4 is a sectional view of the waterproof sleeve in the rectifier cabinet cooling system provided by the embodiment. Specifically, the water pump 2 includes a base 21 and a water pump body 22 connected to the lower end of the base 21, and the size of the base 21 in the horizontal direction is greater than the size of the water pump body 22 in the horizontal direction; the waterproof sleeve 3 includes a first sleeving part 31 and a second sleeving part 32, the second sleeving part 32 is connected to the lower end of the first sleeving part 31, the first sleeving part 31 cooperates with the base 21, and the second sleeving part 32 cooperates with the water pump body 22; wherein the outer diameter of the second sleeving part 32 is smaller than the outer diameter of the first sleeving part 31, and the bottom end of the second sleeving part 32 is open.

[0034] In this way, the shape of the waterproof sleeve 3 is more suitable for the shape of the water pump 2, so that the waterproof sleeve 3 can be reliably sleeved on the water pump 2 to prevent the cooling water from forming a large impact force to cause the waterproof sleeve 3 to fall off.

[0035] Wherein, the first sleeving part 31 is formed with a first matching cavity 311 matched with the base 21, and the second sleeving part 32 is formed with a second matching cavity 321 matched with the water pump body 22, and the first matching cavity 311 and the second matching cavity 321 are communicated. In order to further improve the connection reliability between the waterproof sleeve 3 and the water pump 2, the first matching cavity 311 can be interference-fitted with the base 21, and in order to facilitate the sleeving of the waterproof sleeve 3 on the water pump 2, the second matching cavity 321 can be clearance-fitted with the water pump body 22. In this way, on the one hand, the connection reliability between the waterproof sleeve 3 and the water pump 2 is satisfied, and on the other hand, the waterproof sleeve 3 is facilitated to be sleeved.

[0036] It can be understood that wear and tear can occur during the installation and removal of the waterproof sleeve 3, which can affect the waterproof performance of the waterproof sleeve 3. Based on this, in some optional embodiments, the second sleeve setting part 32 is detachably connected with the first sleeve setting part 31. In this way, the replacement cost of the waterproof sleeve 3 can be reduced, that is, when the first sleeve setting part 31 is worn, only the first sleeve setting part 31 needs to be replaced, and when the second sleeve setting part 32 is worn, only the second sleeve setting part 32 needs to be replaced. In this way, even when the waterproof sleeve 3 is worn out, the corresponding part can be replaced, thereby reducing the replacement cost of the waterproof sleeve 3.

[0037] Please refer to Figure 5 , Figure 5 for Figure 4 the local structure at B in the enlarged schematic view. When the first sleeve setting part 31 is detachably connected with the second sleeve setting part 32, it can be connected by a fastener or can be connected by a clamping connection. It is not difficult to understand that it is more convenient to be connected by a clamping connection. Therefore, as an optional embodiment, one of the first sleeve setting part 31 and the second sleeve setting part 32 is provided with a buckle 33, and the other is provided with a clamping groove 34; the buckle 33 and the clamping groove 34 are connected in a detachable manner to connect the first sleeve setting part 31 and the second sleeve setting part 32.

[0038] In the specific embodiment of the present embodiment, the buckle 33 is provided on the second sleeve setting part 32, the clamping groove 34 is provided on the first sleeve setting part 31, and the buckle 33 comprises a clamping part 331 and a positioning part 332 connected in sequence. The positioning part 332 is connected to the top end of the second sleeve setting part 32 and extends upward in a columnar structure, and the clamping part 331 is connected to the top end of the positioning part 332 and has a circular truncated cone shape. The radial dimension of the top end of the clamping part 331 is smaller than the radial dimension of the bottom end of the clamping part 331. In this way, the relative position between the first sleeve setting part 31 and the second sleeve setting part 32 is limited in the horizontal direction and the vertical direction.

[0039] In order to improve the connection reliability between the first sleeve setting part 31 and the second sleeve setting part 32, the buckle 33 and the clamping groove 34 can be provided in multiple numbers, and one buckle 33 corresponds to one clamping groove 34. In this way, the connection between the first sleeve setting part 31 and the second sleeve setting part 32 is more reliable, so as to avoid the impact of the cooling water being too large and causing the first sleeve setting part 31 and the second sleeve setting part 32 to be separated.

[0040] Further, in order to avoid the structure of the waterproof sleeve 3 and the water pump 2 from affecting each other, in the present embodiment, the waterproof sleeve 3 can be made of a flexible material. Since the size of the base 21 in the horizontal direction is larger than the size of the water pump body 22 in the horizontal direction, in the present embodiment, the first sleeve setting part 31 and the second sleeve setting part 32 are both elastic structures, for example, the first sleeve setting part 31 and the second sleeve setting part 32 can both be made of rubber.

[0041] In this way, on the one hand, the hard contact between the waterproof sleeve 3 and the water pump 2 can be avoided, and the surface structure of the two can be damaged. On the other hand, since the waterproof sleeve 3 is elastic, it is not only convenient to be sleeved on the water pump 2, but also can be reliably connected with the water pump 2 by using its own elasticity.

[0042] Although the rubber itself has waterproof performance, because its own waterproof performance is limited, in order to avoid the influence of the surface structure of the waterproof sleeve 3 caused by the long-term impact of the cooling water, a waterproof layer 35 can be arranged on the outer side of the first sleeve part 31 and the second sleeve part 32. In this way, the waterproof performance of the waterproof sleeve 3 itself can be improved.

[0043] For example, the waterproof layer 35 described above can be a synthetic polymer waterproof roll material. Specifically, the synthetic polymer waterproof roll material is a rollable sheet-shaped waterproof material processed by synthetic rubber, synthetic resin and an appropriate amount of chemical additives and fillers. Here, the material of the waterproof layer 35 is not limited.

[0044] Of course, the waterproof layer 35 will increase the manufacturing cost of the waterproof sleeve 3. In order to avoid the large manufacturing cost of the waterproof sleeve 3, in some optional embodiments, the wall thickness of the first sleeve part 31 and the second sleeve part 32 is greater than the thickness of the waterproof layer 35. In this way, the manufacturing cost of the waterproof layer 35 is low, and the manufacturing cost of the waterproof sleeve 3 is low.

[0045] It should be noted that due to the gravity of the cooling water, in this embodiment, for the first sleeve part 31, the waterproof layer 35 can be arranged at the top end and the side, for the second sleeve part 32, the waterproof layer 35 can be arranged at the side, and the bottom end of the first sleeve part 31 and the bottom end of the second sleeve part 32 can not be provided with the waterproof layer 35. Thus, the manufacturing cost of the waterproof sleeve 3 is further reduced.

[0046] In some other embodiments, in order to improve the manufacturing efficiency of the waterproof sleeve 3, the waterproof sleeve 3 can also be an integral structure. Here, the specific forming method of the waterproof sleeve 3 is not limited.

[0047] The embodiment also provides a rectifier cabinet 10, which comprises a cabinet door 4, a cabinet body 5 and the rectifier cabinet cooling system in the above-mentioned embodiments; the cabinet door 4 is installed on the cabinet body 5 and surrounds the cabinet body 5 to form an installation cavity 6, and the rectifier cabinet cooling system is installed in the installation cavity 6. The structure of the rectifier cabinet cooling system has been described in detail in the above-mentioned embodiments, and will not be repeated here.

[0048] It should be noted that the rectifier cabinet 10 provided in the embodiment further comprises a cooling system control module 7 and the like. Here, other modules or components comprised in the rectifier cabinet 10 provided in the embodiment are not limited one by one.
