Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling of data centers, in particular to a liquid cooling cabinet type dummy load device. Background Art

[0002] Liquid-cooled dummy load equipment refers to an important device used to simulate the heat generated by data center servers under load and test the heat dissipation performance. Its main function is to simulate the load conditions of the server in actual application scenarios and test the server's heat dissipation performance by generating heat. Liquid-cooled dummy loads can not only test the heat dissipation performance of the server, but also help adjust the server's cooling system to optimize the heat dissipation performance of the data center cluster. At present, with the development of servers in the AI field, the power of a single cabinet in a liquid-cooled data center (such as B200 cabinets, GB200 cabinets, etc.) has reached more than 120kW. Conventional rack-mounted liquid-cooled dummy load equipment can no longer meet the performance simulation requirements of high-power servers due to its low heat generation. Utility Model Content

[0003] In view of this, the present invention provides a liquid-cooled cabinet-type dummy load device, which solves the technical problem that the existing liquid-cooled dummy load device cannot take into account the performance simulation requirements of liquid-cooled servers with different power sizes.

[0004] The technical means adopted by the utility model are as follows: a liquid-cooled cabinet-type dummy load device, comprising: a cabinet body, a heating tank is arranged inside the cabinet body, a liquid inlet pipe is arranged on one side of the cabinet body, the liquid inlet pipe is connected to the bottom of the heating tank, a liquid outlet pipe is arranged on the other side of the cabinet body, the liquid outlet pipe is connected to the top of the heating tank, the heating tank is provided with a plurality of electric heating rods inserted horizontally into the heating tank, the liquid inlet pipe is provided with a first pressure sensor, a first regulating valve, a first temperature sensor and a filter, the liquid outlet pipe is provided with a second pressure sensor, a second regulating valve and a second temperature sensor, an air drain valve is provided at the bottom of the heating tank, and an exhaust valve is provided at the top of the heating tank.

[0005] Preferably, water distributors are provided at the top and bottom of the heating tank to evenly distribute the flow and achieve better heating effect.

[0006] Preferably, the electric heating rod is connected to the heating tank by a clamp. Several of them can be inserted to adjust the heating value as needed.

[0007] Preferably, universal wheels are provided at the bottom of the cabinet. As a complete machine, universal wheels are provided for flexible deployment.

[0008] Preferably, a liquid level sensor is provided in the heating tank to detect the liquid level in the heating tank, thereby preventing the heater from drying out and ensuring safe operation of the dummy load.

[0009] The liquid-cooled cabinet-type dummy load device provided by the utility model can adjust the heating demand as needed through the combination design of multiple electric heating rods, control the number of electric heating rods inserted into the heating tank, and realize the adjustment of heating capacity of different power levels of 0 to 120kW. In this way, the heating value of a high-power cabinet load and the rapid change of the load can be simulated to realize the cooling simulation test of the server cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a simplified structural diagram of the utility model. DETAILED DESCRIPTION

[0011] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0012] like Figure 1 As shown, a liquid-cooled cabinet-type dummy load device includes a cabinet body 1, a heating tank 2 is provided in the cabinet body 1, a liquid inlet pipe 3 is provided on one side of the cabinet body 1, the liquid inlet pipe 3 is connected to the bottom of the heating tank 2, and a liquid outlet pipe 4 is provided on the other side of the cabinet body 1, the liquid outlet pipe 4 is connected to the top of the heating tank 2, and the heating tank 2 is provided with a plurality of electric heating rods 5 that are laterally inserted into the heating tank 2. It is easy to understand that the electric heating rods 5 need to be powered on to work. Therefore, in fact, a power distribution part is also provided in the cabinet body 1, and the electric heating rods 5 are connected by wires to work. The power distribution part is a mature existing technology and will not be elaborated here. The liquid inlet pipe 3 is provided with a first pressure sensor 6, a first regulating valve 7, a first temperature sensor 8, and a filter 9. The first pressure sensor 6 and the first temperature sensor 8 are used to monitor the pressure and temperature of the liquid in the liquid inlet pipe 3. The first regulating valve 7 is used to isolate the liquid or adjust the flow rate. The filter 9 filters the liquid in the pipe to maintain the cleanliness of the equipment and the pipe. The liquid outlet pipe 4 is provided with a second pressure sensor 10, a second regulating valve 11, and a second temperature sensor 12. It is easy to understand that the second pressure sensor 10 and the second temperature sensor 12 are used to monitor the pressure and temperature of the liquid in the liquid outlet pipe 4, and the second regulating valve 11 is used to isolate the liquid or adjust the flow rate; a drain valve 13 is provided at the bottom of the heating tank 2 for emptying the liquid in the heating tank 2; an exhaust valve 14 is provided at the top of the heating tank 2 for exhausting the liquid in the heating tank 2.

[0013] Water distributors 15 are provided above and below the interior of the heating tank 2. The upper part of the upper water distributor 15 is the pipe opening where the liquid outlet pipe 4 is connected to the heating tank 2, and the lower part of the lower water distributor 15 is the pipe opening where the liquid inlet pipe 3 is connected to the heating tank 2. The water distributor 15 can slow down the flow rate of the coolant, ensuring that the electric heating rod 5 inside the heating tank 2 can evenly heat the liquid, making the heating efficiency higher.

[0014] The electric heating rod 5 is connected to the heating tank 2 with a clamp to facilitate quick disassembly and maintenance. In terms of installation, the left and right staggered installation design ensures uniform heating and saves installation space. In actual use, the number of electric heating rods 5 to be inserted is selected according to the power of the server to be simulated. In this way, the cooling performance simulation test of servers with different power sizes can be satisfied. In conventional liquid-cooled dummy loads, since the heating power is not high, there are no special requirements for the heating of the cooling medium. In the scenario of high-power liquid-cooled cabinets, the liquid-cooled dummy load is required to have the functions of rapid heating and rapid adjustment to simulate the rapid changes in the load of the high-power liquid-cooled cabinet. Therefore, in terms of functional design, the heat generation in the heating tank 2 can reach up to 120kW, the heat generation can achieve an adjustment accuracy of ±1kW, and the heat generation adjustment time is 10S, simulating the rapid changes in the heat generation and load of the high-power cabinet load, and realizing the cooling simulation test of the server cabinet.

[0015] The bottom of the cabinet 1 is provided with universal wheels 16 for moving the entire device. In addition, a liquid level sensor 17 is provided in the heating tank 2 for real-time monitoring of the liquid level in the heating tank 2 to ensure safe operation of the device.

[0016] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
