Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation recovery, and more specifically, it relates to an electric energy recovery system applicable to high-computing-power servers of large models. Background Art

[0002] With the rapid development of artificial intelligence large models, the demand for server computing power in related research and commercial implementation is getting higher and higher. However, high-computing-power servers will generate a large amount of heat during operation and release it into the air for a long time. This will not only lead to low efficiency of high-computing-power servers, but even damage the hardware of the servers.

[0003] Currently, most high-computing-power servers do not recover the heat they release, and in order to prevent the servers from overheating, this part of the heat needs to be discharged by means such as exhaust fans, consuming additional energy. In addition, some existing technologies record heat dissipation recovery power generation systems applied to other devices, such as a heat dissipation recovery power generation system for a diesel generator set with the application number CN201621110130.1, but it cannot be directly applied to computing power servers.

[0004] Therefore, how to research and design an electric energy recovery system applicable to high-computing-power servers of large models is an urgent problem for us to solve at present. Content of the Utility Model

[0005] To solve the deficiencies in the prior art, the purpose of the utility model is to provide an electric energy recovery system applicable to high-computing-power servers of large models, which converts the heat generated during the operation of high-computing-power servers into electric energy and incorporates it into the power input end of the high-computing-power servers to jointly supply power to the high-computing-power servers together with the mains power supply, so as to overcome the defects that high-computing-power servers do not recover the heat generated during operation, resulting in a waste of energy, and the traditional heat dissipation method also requires additional power consumption.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: An electric energy recovery system applicable to high-computing-power servers of large models includes a thermoelectric power generation array, a first voltage stabilizing capacitor, an anti-backflow charging diode, a single-phase full-bridge fully controlled inverter module, a second voltage stabilizing capacitor, a single-phase AC transformer, an uninterruptible power supply, and a server power adapter;

[0007] The output end of the thermoelectric power generation array is connected to the DC input end of the single-phase full-bridge fully controlled inverter module through the first voltage stabilizing capacitor and the anti-backflow charging diode;

[0008] The single-phase AC output end of the single-phase full-bridge fully controlled inverter module is connected to the input end of the single-phase AC transformer through the second voltage stabilizing capacitor;

[0009] The output terminal of the single-phase AC transformer is connected to the single-phase output terminal of the server power adapter to jointly charge the uninterruptible power supply;

[0010] The uninterruptible power supply charges the high-computing power server.

[0011] Furthermore, the system further includes a thermoelectric power generation system control module;

[0012] The thermoelectric power generation system control module is connected to the single-phase full-bridge controlled inverter module, collects the signals of the single-phase full-bridge controlled inverter module, and controls its normal operation.

[0013] Furthermore, when the thermoelectric power generation system control module collects the input DC voltage signal of the single-phase full-bridge controlled inverter module, according to the output rated AC voltage value, it outputs corresponding control signals to control the output voltage of the single-phase full-bridge controlled inverter module at the rated voltage.

[0014] Furthermore, the thermoelectric power generation system control module uses an STM32F103 microcontroller.

[0015] Furthermore, the system further includes a time relay and an alarm module;

[0016] The signal acquisition end of the time relay is connected to the output end of the thermoelectric power generation array, the power supply end of the time relay is connected to the output end of the uninterruptible power supply, and the output end of the time relay is connected to the input end of the alarm module.

[0017] Furthermore, the time relay collects the output voltage of the thermoelectric power generation array. When the output voltage of the thermoelectric power generation array continuously exceeds the threshold within the set time, the time relay will conduct to activate the alarm module to achieve high-temperature alarm.

[0018] Furthermore, the time relay uses an electromechanical time relay, and the alarm module uses a 220V electromagnetic buzzer.

[0019] Furthermore, the thermoelectric power generation array is composed of multiple TEG1 thermoelectric power generation chips connected in series.

[0020] Furthermore, one side of the thermoelectric power generation array as the hot end is close to the server, and the other side as the cold end is far from the server.

[0021] Furthermore, the uninterruptible power supply uses a UPS uninterruptible power supply battery.

[0022] Compared with the prior art, the present utility model has the following beneficial effects:

[0023] 1. The power energy recovery system for high computing power servers applicable to large models provided by the present utility model adopts the thermoelectric power generation technology to recover and convert the energy dissipated as heat by the high computing power servers into electric energy. The recovered electric energy is fed back to the power input end of the servers through the inversion technology and jointly powers the servers with the commercial power supply, improving the overall efficiency of the servers and being more energy-saving.

[0024] 2. When the output voltage of the thermoelectric power generation array exceeds the threshold for a long time, it indicates that the server is in a high temperature environment for a long time. At this time, the time relay will conduct, thus starting the alarm module to give an alarm. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The output voltage value of the thermoelectric power generation array 6 is positively correlated with the temperature difference between its two ends (cold end and hot end). When the server is running, the thermoelectric power generation array 6 outputs unstable direct current electricity, which is converted into stable alternating current electricity through the DC-AC conversion of the single-phase full-bridge controlled inverter module 7.
