[0002] At present, the market's requirements for reducing energy consumption in data centers and their servers are constantly increasing. Server motherboards need to reduce the copper sheet power loss on the single board from the source to reduce the overall power consumption of the data center and save costs. Currently, multiple VR power supplies on server CPUs output large currents, and the circuit paths are long, resulting in large copper sheet power losses.

[0003] The distance between the VR multi-power supply and the CPU pin receiving power supply is about 70mm. Taking the Intel 350W CPU as an example, the Vcore (CPU core power supply) TDC continuous current is about 220A, and the Rpath (power supply return path impedance) is about 0.296mohm, resulting in about 14.3W of copper skin power loss in this part of the circuit. This additional loss leads to an increase in electricity costs, and there is currently a lack of optimization technical solutions. Summary of the invention

It should also be understood that the term "and / or" used herein refers to any or all possible combinations of one or more associated listed items.

[0025] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this specification. Instead, they are merely examples of devices and methods consistent with some aspects of this specification as detailed in the appended claims.

[0026] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of this specification, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this specification, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, in addition, the word "if" used may be interpreted as "at the time of" or "when" or "in response to determining".

[0027] In one technical solution, the above problem is alleviated by increasing the PCB thickness or the number of layers, but this may cause a significant increase in costs; or the VR multiple power supply limits are placed close to the CPU end to reduce the loss path distance, but due to process and structure limitations, this distance has a limit.

[0028] In view of this, the present specification provides a PCB circuit board, a processor fixing seat and a computer device to at least improve one of the above technical problems.

[0029] The specific technical solution is described below.

[0030] The present specification provides a PCB circuit board, including a processor mounting slot and a power supply module, and the PCB circuit board is provided with a bus bar; the processor mounting slot is provided on the front side of the PCB circuit board, and the bus bar is provided on the back side of the PCB circuit board; the bus bar is provided on the back side of the PCB circuit board at a position corresponding to the processor mounting slot, and extends to the position of the power supply module; the bus bar establishes electrical connections with the processor mounting slot and the power supply module respectively, and the bus bar forms a protrusion on the back side of the PCB circuit board where the bus bar is provided.

[0031] A bus bar is set on the back of the mainboard PCB circuit board, which connects the processor and the power supply module to provide a low-impedance processor power supply circuit, reduce energy loss in the circuit, and at the same time reduce the requirements for the power supply circuit on the PCB circuit board, simplifying the wiring difficulty inside the mainboard PCB circuit board.

[0032] As a technical solution, the bus bar is covered with an insulating layer on the protrusion formed on the back side of the PCB circuit board where the bus bar is arranged.

[0033] As a technical solution, the resistance of the electrical path formed by the bus bar is less than a preset resistance threshold.

[0034] As a technical solution, the length L of the busbar in the direction of connecting the processor installation slot and the power supply module is configured, the busbar is configured using a material with an average resistivity of ρ, and the busbar is configured perpendicular to the average cross-sectional area S in the direction of connecting the processor installation slot and the power supply module, so that the value of the resistance R obtained by multiplying L by ρ and dividing S is less than the preset resistance threshold. According to the requirements of the preset resistance threshold, the material and size of the busbar are configured, and the height of the busbar that can protrude beyond the PCB circuit board should generally not exceed the thickness of the processor fixing seat.

[0035] As a technical solution, the busbar is configured using a material with a resistivity lower than 0.02 ohm x meter at standard atmospheric pressure and 20 degrees Celsius. A preferred material is copper, and other materials that meet the requirements may also be used.

[0036] As a technical solution, two ends of the bus bar extend according to the structures of the processor mounting slot and the power supply module respectively.

[0037] The present specification also provides a processor fixing seat, which is used to cooperate with a processor fastener to fix a processor device installed in any of the aforementioned processor mounting slots, including a connector for cooperating with the processor fastener. The processor fixing seat is detachably arranged on the back side of any of the aforementioned PCB circuit boards at a position corresponding to the processor mounting slot; a groove is provided on the processor fixing seat at a position corresponding to any of the aforementioned bus bars, and the groove is used to accommodate the bus bar.

[0038] The size of the groove may be larger than the protrusion of the bus bar, or the size of the groove may be set in a more fitted manner, so as to utilize the processor fixing seat to dissipate heat for the circuit.

[0039] As a technical solution, the inner wall of the groove for accommodating the bus bar is covered with an insulating layer.

[0040] The present specification also provides a computer device, including any one of the aforementioned PCB circuit boards and any one of the aforementioned processor fixing seats, and also including a processor device and a power supply device. The processor device is detachably arranged in the processor mounting slot of the PCB circuit board, and is fixed by the cooperation of the processor fixing seat and the processor fastener. The processor and the power supply device establish a power supply connection through the processor mounting slot, the bus bar, and the power supply module.

[0041] By implementing the better technical solutions in the above implementation mode, it can be achieved that Rpath is reduced from approximately 0.296mohm to below 0.2mohm under the premise that other technical solutions remain unchanged, thereby reducing the power loss of this part by about 1 / 3. Taking the conventional configuration of two CPUs as an example, a single server can reduce power consumption by about 10W, reduce heat generation, and reduce the difficulty of heat dissipation.
