[0032] Example 1

[0033] Figure 1 This is a schematic diagram of the interior of the chassis 1 of a drawer-type module provided in one embodiment of this utility model. Figure 1 As shown, a drawer-type module integrating a CDU control unit and a PDU unit includes: a chassis 1 for independently deploying the CDU control unit and the PDU unit. In this embodiment, the chassis 1 consists of a housing and a cover on the top of the housing. The cover is connected to the housing by screws. The CDU control unit and the PDU unit are deployed inside the housing 1. Therefore, by independently deploying the CDU control unit and the PDU unit, this embodiment achieves complete physical separation from the liquid circuit CDU module, completely eliminating the risk of electrical accidents caused by leakage and greatly improving the safety of data center operation.

[0034] In this embodiment, the chassis 1 is provided with a cable management box 2 for placing the cables of the CDU control unit and the PDU unit. The cable management box 2 divides the interior of the chassis 1 into multiple installation areas, and the CDU control unit and the PDU unit are deployed in different installation areas. Therefore, the cables between the CDU control unit and the PDU unit can be deployed through the cable management box 2, making the layout of the components inside the chassis 1 neater and more reasonable, and facilitating the maintenance of the components inside the chassis 1.

[0035] The CDU control unit and PDU unit include a power connector 3 and a signal connector 4, which are spaced apart on the rear end face of the chassis 1, as shown below. Figure 3 As shown.

[0036] In this embodiment, the power connector 3 is used to connect to a 220V AC power supply, and the signal connector 4 is used to connect to the liquid circuit CDU module, mainly for transmitting weak electrical signals; the liquid circuit CDU module is equipped with a temperature sensor and a leakage sensor, which can be connected to the signal connector 4 via a signal line.

[0037] Therefore, in this embodiment, the power connector 3 and the signal connector 4 are deployed at intervals on the rear end face of the chassis 1, that is, the physical distance is used to achieve isolation between high voltage (AC power) and low voltage (signal), reduce electromagnetic interference, and improve stability.

[0038] In this embodiment, the CDU control unit mainly consists of a PLC, digital input modules, a switch, a touch screen 5, relays, a water leakage detector, a current transformer, and terminal blocks. The digital input modules are connected to the PLC, the switch is connected to the digital input modules, the terminal blocks are connected to the PLC, and the signal output terminal of the current transformer is connected to the terminal blocks. The terminal blocks are mainly used to receive analog signals. The current transformer is used to collect the current signal of the AC power supply. The coil control terminal of the relay is connected to the PLC, and the relay switch is connected in series in the power supply circuit of the current transformer. The PLC can control the operation of the corresponding current transformer.

[0039] Among them, the touch screen 5 is connected to the PLC and is used to visualize the current signal collected by the current transformer. The water leakage detector is connected to the PLC. There are two water leakage detectors, one for monitoring the cabinet and the other for monitoring the liquid circuit CDU module.

[0040] The switch in this embodiment is connected to network port 6. The switch uploads relevant data (such as current signals) to the data center management system through network port 6 to achieve remote monitoring. The CDU control unit in this embodiment uses existing control circuits, and its specific circuit structure is not described in detail in this embodiment.

[0041] In this embodiment, the PDU unit includes a DC power supply, a leakage current detector, multiple contactors, multiple circuit breakers 7, fuses 13, and a server interface 8. One AC power supply is connected to the DC power supply. The DC power supply includes a rectifier that converts the AC power supply (e.g., AC220V) into low-voltage DC (DC24V). The DC power supply is used to provide operating power for the PLC. The power cable between the DC power supply and the PLC can be deployed through the cable management box 2.

[0042] Another AC power supply is connected to the contactor, and a fuse 13 is connected in series between the AC power supply and the contactor, providing overcurrent protection. Each contactor is connected to a circuit breaker 7, which is then connected to the server interface 8. After passing through the contactor, the AC power supply is controlled by the circuit breaker 7 to output from the server interface 8. In this embodiment, the circuit breaker 7 is controlled by a PLC. When faults such as overcurrent, leakage, or liquid leakage occur, the PLC can control the circuit breaker 7 to trip, thereby cutting off the power output of each server interface 8 and achieving rapid protection.

[0043] In this embodiment, the touchscreen 5, network port 6, fuse 13, multiple circuit breakers 7, and multiple server interfaces 8 are deployed on the front of the chassis 1, as shown below. Figure 2 As shown, this layout is easy to operate and maintain in daily life.

[0044] In this embodiment, guide rails can be deployed on both sides of the chassis 1. At this time, the entire chassis 1 can be easily pushed into or pulled out of the data center cabinet like a server, realizing drawer-style installation and replacement.

[0045] Example 2

[0046] Based on Embodiment 1, the cable management box 2 in this embodiment includes: a first box body 201, a second box body 202 and a third box body 203. The first box body 201 extends along the width direction of the chassis 1, and the second box body 202 and the third box body 203 both extend along the length direction of the chassis 1. The second box body 202 and the third box body 203 are both connected to the first box body 201. The side walls of the first box body 201, the second box body 202 and the third box body 203 are all provided with cable holes 204.

[0047] In this embodiment, as Figure 5 As shown, the first box 201, the second box 202, and the third box 203 can be integrally formed. The first box 201, the second box 202, and the third box 203 can be fixed inside the chassis 1 by using bolts or screws through mounting holes at the bottom. In this embodiment, the two ends of the first box 201 directly abut against the inner sidewalls of the left and right sides of the chassis 1. At this time, the first box 201 divides the interior of the chassis 1 into two regions, namely a front chamber and a rear chamber. The second box 202 and the third box 203 are located inside the rear chamber, which can further divide the rear chamber into three regions, namely a rear left chamber, a rear middle chamber, and a rear right chamber. Therefore, the interior of the chassis 1 is divided into a total of four regions. Regarding the deployment positions of the components of the CDU control unit and the PDU unit, as follows... Figure 4 As shown.

[0048] exist Figure 4 In the middle, the front chamber mainly houses touch screen 5 and circuit breaker 7, the rear left chamber mainly houses PLC, digital modules, switch, water leakage detector, relay, current transformer, terminal block, etc., the rear middle chamber mainly houses contactor and leakage detector, and the rear left chamber mainly houses DC power supply, etc.

[0049] In this embodiment, the length of the second housing 202 is less than the length of the third housing 203, so that the current transformer can be deployed near the end of the second housing 202, making the current transformer closer to the AC power cable.

[0050] Therefore, through the above layout, this embodiment makes the layout of the internal components of the chassis 1 neater and more reasonable, which facilitates the maintenance and operation of the internal components of the chassis 1.

[0051] Example 3

The cover plate 206 has at least one crease 207. Figure 7 and Figure 8 As shown, a blocking block 208 is provided on the inner side of the cover plate 206. The blocking block 208 is inserted into the opening 205 and forms an interference fit with the opening 205.

[0053] In this embodiment, when it is necessary to replace or partially route the cables in the cable tray 2, a portion of the cover plate 206 can be removed without disassembling the entire cover plate 206, thus improving the convenience of operation.

[0054] Example 4

[0055] Based on Embodiment 1, in this embodiment, protective caps 9 can be detachably connected to both the signal connector 4 and the network port 6. The protective cap 9 consists of a cap cover, a cap ring, and a connecting strap. One end of the connecting strap is connected to the edge of the cap ring, and the connecting strap can be integrally formed with the cap ring. The other end of the connecting strap is rotatably connected to the center of the end face of the cap cover. The cap ring is fixed on the signal connector 4 and the network port 6, and the cap cover can be inserted into the signal connector 4 and the network port 6, which can play a protective role for the signal connector 4 and the network port 6.

[0056] Furthermore, a number of heat dissipation holes 10 are provided on the rear end face of the chassis 1, and a temperature and humidity sensor 11 is provided on the rear end of the chassis 1. The temperature and humidity sensor 11 is connected to the PLC, and the probe of the temperature and humidity sensor 11 is located outside the chassis 1 to detect the ambient temperature and humidity.

[0057] As a further optimization of this embodiment, such as Figure 2 As shown, U-shaped handles 12 are provided on both sides of the front of the chassis 1, and the two ends of the handles 12 are hinged to the front of the chassis 1. In this embodiment, by providing handles 12, it is convenient to take the chassis 1 out and put it in.
