The cabinet body 100 is a square structure with a hollow interior. The electric control unit 200 is rotatably arranged on the middle front side of the cabinet body 100, and the working unit is arranged in the cabinet body 100. After the electric control unit 200 is rotated toward the outside of the cabinet body 100, the working unit can be removed from the front side of the cabinet body 100.

[0057] In this embodiment, the height of the cabinet 100 of the liquid cooling unit cabinet is about 2.4 meters, and the width of each side is about 1.5 meters. The cabinet is large and the internal space is messy and inconvenient for maintenance. Figure 1 As shown, a rectangular empty space is provided in the middle of the front side of the cabinet 100. The electric control unit 200 of this embodiment is an independent integral part.

In this embodiment, the electric control unit 200 can rotate relative to the cabinet 100. Figure 1 In this embodiment, the electric control unit is installed at the front right side of the cabinet 100, and the rightmost side of the electric control unit is aligned with the right edge of the cabinet. The electric control unit can be opened from the right side. When opened, the electric control unit rotates from the front side of the cabinet to the left, and can be opened to a position at a 90-degree angle relative to the cabinet. In other implementations, the electric control cabinet 200 can also be rotated from right to left according to design requirements, and rotated to a position at a 180-degree angle to the cabinet 100. When the electric control unit rotates, the electrical components installed on the electric control unit rotate with the electric control unit. Figure 1 As shown, in this embodiment, the right side of the electric control cabinet is flush with the edge of the cabinet, and the left side has a preset distance from the cabinet. And the electric control unit is also at a preset distance from the upper and lower sides of the cabinet. In this embodiment, the left side of the electric control unit is 10 cm away from the cabinet, and the distance between the upper side of the electric control cabinet and the top of the cabinet is greater than the thickness of the plate heat exchanger 510. When the electric control empty unit is rotated and closed on the cabinet. The entire liquid cooling unit cabinet is a square rectangular structure. After the electric control unit is rotated and closed, the cabinet 100 can be sealed to protect the pipes, instruments and heat exchange equipment inside the cabinet 100. The electric control unit 200 is embedded in the cabinet 100 and can be rotated toward the outside relative to the cabinet 100, so that the cabinet 100 and the electric control unit 200 are combined together to improve the overall utilization and efficiency. In addition, the space installation of the pipes, instruments, and heat exchange equipment inside the cabinet 100 further improves the internal space utilization of the cabinet 100, allowing the coolant distribution unit cabinet to complete the heat exchange of the coolant in a limited space.

[0058] In this embodiment, all the electric control components in the liquid cooling unit cabinet are arranged inside the electric control unit, and the electric control unit is connected to the internal components and the external power supply and communication through lines.

Among them, the protective cover 210 is made of acrylic material, which has good transparency, chemical stability and weather resistance, is easy to dye, easy to process and has a beautiful appearance, and the acrylic material is transparent, so the working state of the switch can be observed. In addition, the protective cover 210 can rotate relative to the mounting frame 220, and while protecting the electric control unit 200, it is convenient to control the electric control unit 200 covered by the protective cover.

[0065] Among them, the protective cover 210 includes a first protective plate 2110 and a second protective plate 2120, the first protective plate 2110 and the second protective plate 2120 are arranged on the front side of the mounting frame 220, the first protective plate 2110 is away from the side of the second protective plate 2120, and is hingedly connected to the mounting frame 220, and the second protective plate 2120 is away from the side of the first protective plate 2110, and is hingedly connected to the mounting frame 220.

[0067] In combination with Example 1, in a specific embodiment, the working unit includes: a plate heat exchanger 510, a primary inlet pipe 580, a primary outlet pipe, a secondary inlet pipe 530 and a secondary outlet pipe 520. The inlet end of the primary inlet pipe 580 is used to connect to a cooling tower and connect to a coolant with lower heat, and the outlet end is connected to the first inlet of the plate heat exchanger 510. The inlet end of the primary outlet pipe is connected to the first outlet of the plate heat exchanger 510 to transport the coolant with higher heat after heat exchange to the cooling tower. The inlet end of the secondary inlet pipe 530 is used to connect to the liquid cooling pipe of the cabinet, and the outlet end is connected to the second inlet of the plate heat exchanger 510 to transport the coolant with higher heat after cooling the cabinet to the plate heat exchanger 510. The inlet end of the secondary outlet pipe 520 is connected to the second outlet of the plate heat exchanger 510, and the outlet end is connected to the liquid cooling pipe, so that the coolant with lower heat after heat exchange is transported to the cabinet to cool the cabinet. Among them, the primary inlet pipe 580, the primary outlet pipe, the secondary inlet pipe 530 and the secondary outlet pipe 520 are all arranged vertically, respectively arranged at various corners inside the cabinet 100, so as to improve the space utilization inside the cabinet 100 and reserve space for installing other equipment.

[0068] In this embodiment, the electric control unit is located in the middle of the cabinet in the vertical direction, the plate heat exchanger and the frequency converter are located at the top of the cabinet, and the liquid storage tank is located at the top of the cabinet.

[0070] Furthermore, in this specific embodiment, the working unit also includes: a liquid storage tank 570 and a liquid replenishing pump. Specifically, the liquid storage tank 570 is connected to the circulation pump 550 in sequence and is arranged at the end of the conductivity meter. Extra coolant is stored inside the liquid storage tank 570. When the coolant inside the overall pipeline is lost, the coolant inside the secondary inlet pipeline 530 sucked from the liquid storage tank 570 can be replenished by the liquid replenishing pump. In addition, the coolant inside the liquid tank is at room temperature, so the connection between the output end of the liquid replenishing tank and the secondary inlet pipeline 530 can enable the replenished coolant to be transported to the plate heat exchanger 510 for heat exchange, and the coolant with lower heat after heat exchange is transported to the cabinet for cooling.

[0071] Furthermore, in this specific embodiment, it also includes: a circulation pump 550, which is arranged between the safety valve and the liquid replenishing tank of the secondary inlet pipe 530, so as to pump the coolant inside the secondary inlet pipe 530 to the plate heat exchanger 510.

[0077] Embodiment 3,

[0078] In combination with Example 2, in a specific embodiment, the liquid storage tank 570 is arranged at the bottom end of the cabinet 100 and is located directly below the electronic control unit 200. The circulation pump 550, the expansion tank 540 and the liquid replenishing pump are all arranged at the front side of the cabinet 100, and are arranged in sequence from the bottom to the top of the cabinet 100. When the electronic control unit 200 located at the front side of the cabinet 100 is opened, the circulation pump 550, the expansion tank 540 and the liquid replenishing pump can be repaired or replaced, which is more convenient to use.

[0079] In a specific embodiment, the working unit further includes: a frequency converter 310, which is connected to other electrical devices such as the electric control unit 200 and the plate heat exchanger 510, and can convert a current of one frequency into a current of another frequency.

[0080] In this embodiment, each device inside the cabinet is modularized. Figure 2 and Figure 3 The electric control unit is located at the front side of the cabinet, and the pipelines included in the working unit are located at the rear side of the cabinet, so that the pipelines of the electric control unit and the working unit are arranged front and back in the horizontal direction. Figure 4In the vertical direction of the cabinet, the inverter of the working unit is located directly above the electric control unit, and the liquid storage tank is located directly below the electric control unit. Therefore, the inverter, the electric control unit and the deliquidation tank do not interfere with the pipeline of the working unit in the horizontal direction, and the installation space of the liquid storage tank and the inverter are equal to the thickness and width of the electric control unit, thereby separating them from the interior of the cabinet. In addition, the plate heat exchanger is set in the same space as the pipeline, located directly above the pipeline, and is not on the same horizontal plane as the electric control unit. After opening the electric control unit, the pipeline inside the cabinet and the bottom of the plate heat exchanger can be directly observed without observing the plate heat exchanger located above the pipeline, the liquid storage tank located at the bottom of the electric control unit and the inverter located at the top of the electric control unit. Among them, the primary inlet pipeline of the working unit is vertically set on the left side of the rear side of the cabinet, and the primary outlet pipeline is vertically set on the left side of the front side of the cabinet, corresponding to the primary inlet pipeline on the rear side. The secondary inlet pipe of the working unit is set on the right side of the rear side of the cabinet, and the secondary outlet pipe is set on the right side of the front side of the cabinet, and is set in front and behind the secondary inlet pipe, so that there is a spare space between the primary inlet pipe, the primary outlet pipe, the secondary inlet pipe and the secondary outlet pipe, which is convenient for the operation and maintenance personnel to repair and replace the four pipes through the reserved spare space after opening the electric control unit. The circulation pump and the expansion tank are set up and down, and the expansion tank is set above the circulation pump, and are both placed on the right side of the front side of the cabinet, close to the position where the electric control unit is rotatably connected to the cabinet. When the electric control unit is opened, the circulation pump and expansion tank set up and down will not hinder the sight of the operation and maintenance personnel.

[0081] In a specific embodiment, the bottom of the cabinet 100 is a sealed structure, and four fixing parts 400 are arranged at the bottom of the cabinet 100, which are arranged circumferentially at the bottom corners of the cabinet 100. The fixing parts 400 are columnar structures as a whole, which can provide stable support for the cabinet 100. In addition, the axial length of the fixing parts 400 is in the range of 20 mm to 30 mm, and the four fixing parts 400 form a relatively stable square structure.

[0082] Example 4

[0083] In combination with Example 3, in a specific embodiment, the mounting frame 220 provided with the electric control unit 200 can be rotated toward the outside relative to the cabinet 100. Among them, one side of the mounting frame 220 in the horizontal direction is connected to the cabinet 100 for horizontal rotation, and the empty space of the square structure is connected to the cabinet 100 away from the rotating side of the mounting frame 220, and when the mounting frame 220 is rotated to the cabinet 100, the front side of the mounting frame 220 is flush with the front side of the cabinet 100, and the side of the mounting frame 220 away from the rotating side is flush with the cabinet 100.

[0084] In a specific embodiment, a wiring trough 110 is provided on the front side of the cabinet 100 and adjacent to the rotating side of the mounting frame 220. The wiring trough 110 is vertically arranged and communicates with the interior of the mounting frame 220 and the interior of the cabinet 100, so that the wires of the electric control unit 200 and the electrical equipment can be arranged inside the wiring trough 110, making the interior of the cabinet 100 tidier. In addition, collecting the wires of the electric control unit 200 and the electrical equipment inside the wiring trough 110 can also prevent dripping coolant from dripping on the wires, thereby providing overall safety performance.

[0085] In this embodiment, refer to Figure 3 and Figure 4 The wiring trough 110 and the electronic control unit are located on the same vertical plane and are both located on the front side of the cabinet. The opening direction of the wiring trough 110 is the height direction of the cabinet, forming a rectangular space that passes through the inverter located at the top of the electronic control unit and the liquid storage tank located at the bottom of the electronic control unit. The wiring trough has open structures at both ends, which can allow the electrical wires and data cables of the inverter, plate heat exchanger and instrument to enter the interior of the wiring trough from the two openings above and below the wiring trough and be electrically connected to the electrical components of the electronic control unit.

[0086] In this embodiment, refer to Figure 4 and Figure 5 The expansion tube and the refill pump are installed inside the cabinet and located at the front side of the cabinet, which is closer to the rotatable electronic control unit than the pipeline, making it easier to repair and replace. In addition, due to the large volume of the expansion tube, the expansion tank is optimized into a rectangular structure, which is vertically arranged inside the cabinet and placed at the back of the wiring trough, so that the operation and maintenance personnel can repair the expansion tank and deeper pipelines after opening the electronic control unit. Since the expansion tank is placed at the back of the wiring trough, a large space is left for repairing and replacing pipelines.

[0087] Further, in this specific embodiment, the wiring trough 110 is a square hollow structure and is vertically arranged. The wiring trough 110 and the electric control unit 200 are both arranged on the front side of the cabinet 100 and on the same side wall of the cabinet 100.
