Description

TECHNICAL FIELD

[0001] The present specification relates to the technical field of communication, and in particular, to a power adapter, a blade server, a power-using device and a power module. BACKGROUND

[0002] With the rapid development of information technology, the market of data centers and servers has an increasing demand for high-performance and high-reliability power supply systems. In some markets, regulations require that blade servers must use power supplies that meet the Titanium certification to meet the energy efficiency and environmental protection requirements of CE certification. This requirement poses new challenges to the power supply design of blade servers.

[0003] At present, the blade server commonly uses a customized blade power supply, such as PSR3000-12A. Although such a power supply has reached the 80PLUS Platinum certification standard and has a maximum power consumption of 3000W, it has significant differences in the external structure from the commonly used CRPS (Common Redundant Power Supply) power supply, resulting in being unable to be directly replaced and applied. This structural difference causes a space limitation in power supply selection, affecting the flexibility and compatibility of the blade server.

[0004] In order to meet the requirements, a Titanium power supply with the same external specifications as the existing blade server needs to be re-customized. This process involves complex engineering and certification procedures, and a long development cycle directly affects the market delivery time, resulting in being unable to quickly respond to market demand and regulatory changes. During the long development process, a large amount of manpower, material resources and financial resources need to be invested, and at the same time, uncertain factors such as project changes, rework and delays may occur, which significantly increases the overall development cost.

[0005] The customized Titanium power supply is specially developed for a specific blade server in terms of external specifications and interface design, which makes it unable to be used in other models or series of products. This special design limits the applicability and flexibility of the product, making it difficult to form a standardized solution. Due to the special characteristics of the Titanium power supply, its materials and components cannot be shared with other existing products, resulting in increased complexity of material management and rising inventory costs. SUMMARY

[0006] Therefore, the present specification provides a power adapter, a blade server, a power-using device and a power module to at least improve one of the above technical problems.

[0007] Specifically, the technical solutions are as follows:

[0008] The power adapter provided by the present specification comprises a main body, a receiving cavity provided on the main body, the receiving cavity being used for accommodating and installing a preset target type power module, an outer surface of the main body being matched with a power installation compartment of a preset target type power consuming device, an input interface provided inside the receiving cavity of the main body and used for being matched and connected with a power supply port of the preset target type power module, and an output interface provided on the outer surface of the main body and used for being matched and connected with a power receiving port of the preset target type power consuming device, wherein part or all pins of the input interface and the output interface are matched through a preset conversion rule, and an electrical connection is provided between the matched pins.

[0009] As a technical solution, the receiving cavity is used for accommodating and installing a CRPS power module.

[0010] As a technical solution, the outer surface of the main body is matched with a power installation compartment of a target blade server.

[0011] As a technical solution, part or all pins of the input interface and the output interface are matched through a preset conversion rule, and an electrical connection is provided between the matched pins, including that part or all signal pins of the input interface and the output interface are connected through an I2C channel according to the preset conversion rule.

[0012] The present specification also provides a blade server comprising a plurality of power installation compartments, wherein each power installation compartment is provided with the power adapter according to any one of the above technical solutions, and a CRPS power module is installed in the power adapter.

[0013] The present specification also provides a power consuming device comprising a power installation compartment, wherein the power installation compartment is provided with the power adapter according to the above technical solution, a power receiving port is provided in the power installation compartment, and the power receiving port is matched and connected with the output interface of the power adapter according to the above technical solution.

[0014] The present specification also provides a power module installed in the receiving cavity of the power adapter according to the above technical solution, wherein the power module comprises a power supply port, and the power supply port is matched and connected with the input interface of the power adapter.

[0015] The above technical solution provided by the present specification at least has the following beneficial effects:

[0016] The blade server can be compatible with commonly used CRPS power modules, while the key performances such as power efficiency, size matching and mechanical fixation, electrical connection and compatibility, and heat dissipation management are retained. The innovative design can greatly shorten the design period of redeveloping a power interface, reduce the cost, and improve the market adaptability and competitiveness of the product.

DETAILED DESCRIPTION

[0027] The terms used in the embodiments of the present specification are only for the purpose of describing specific embodiments, and not for limiting the present specification. The singular forms "a", "an" and "the" used in the present specification and claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein means any or all possible combinations of one or more associated listed items.​

[0028] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description herein refers to the accompanying drawings, which show by way of illustration various

[0029] It should be understood that although the terms first, second, third, etc. can be used herein to describe various information, these terms are not intended to denote a particular order or hierarchy among the information. These terms are used merely to distinguish one type of information from another. For example, a first information can be termed a second information, and similarly, a second information can be termed a first information without departing from the scope of the present description. Furthermore, the word "if" can be interpreted to mean "upon" or "when" or "in response to determining" depending on the context.

[0030] In the field of data center and server applications, the efficiency, reliability and compatibility of power supply are important factors that determine the overall performance of the system. With the development of information technology and the increasing strictness of environmental regulations, the market demand for high-performance, low-power data center equipment is growing. In some regions, new energy efficiency and environmental standards (such as Titanium Gold certification) require blade servers to use power supplies that meet these high standards.

[0031] Currently, a high-efficiency power supply PSR3000-12A is customized for a certain type of blade server. This power supply has reached the 80 PLUS Platinum certification standard and has a maximum power consumption of 3000W. Although this power supply has high energy conversion capability, it has significant differences in the shape and structure from the commonly used CRPS (Common Redundant Power Supply), which leads to limitations in matching space and cannot be directly replaced or applied to existing blade products. In addition, since the conventional power supply used by the existing blade server is only this one, it has affected the flexibility and adaptability of the product to a certain extent.

[0032] In order to ensure that the blade server can obtain CE certification, the power supply used must meet the standards of Titanium Gold certification. This means not only further improving energy efficiency, but also meeting strict environmental requirements. However, redeveloping a new power supply that fully meets the standards of Titanium Gold certification is a complex and time-consuming process. The long development cycle not only increases financial costs, but also delays market response speed, which is not conducive to the rapidly changing market demand.

[0033] From project initiation, circuit and PCB design, prototype manufacturing, processing assembly to the final test and certification, the whole process takes about 15 months. This is undoubtedly a long time for the highly competitive server market, which may result in missing important business opportunities. The newly developed Titanium Gold power supply is usually customized for a specific model of a blade server, which limits its application in other product lines and increases the material management and inventory costs. In addition to the time cost, the development of a new Titanium Gold power supply requires a large amount of investment in funds and technical resources, including human resources, production equipment, and possible rework and delay costs.

[0034] In view of the above, there is an urgent need for a technical solution that can quickly respond to demand while reducing costs. Specifically, the ideal solution should maintain power efficiency, ensure that the high performance of the CRPS power supply is not affected, and continue to meet the corresponding energy efficiency standards; size matching and mechanical fixation, provide effective size adjustment and mechanical fixation devices to ensure that the CRPS power supply can be stably installed in the existing blade power interface; electrical connection and compatibility, through a customized PCB or wiring board, ensure that the electrical connection of the CRPS power supply and the blade system is fully compatible, covering all necessary pin configurations and voltage and current specifications; heat dissipation management, design a reasonable heat dissipation scheme without affecting power ventilation and heat dissipation, and ensure the stable operation of the system.

[0035] In view of the above technical problems, the present specification provides a power adapter, a blade server, a power supply module, and an electrical equipment. The technical solution aims to achieve the compatibility of the blade server with the CRPS Titanium Gold power supply through lower time cost, labor cost, and material cost. Not only does it solve the problem of the current blade server being unable to use conventional CRPS models of power supply, but it also provides a more flexible and efficient solution, which helps to shorten the product launch time, reduce research and development costs, and enhance the market adaptability and competitiveness of the product.

[0036] The specific technical solution is described as follows.

[0037] In an embodiment, as Figure 1 , Figure 2 , Figure 3 The present specification provides a power adapter, a main body, a receiving cavity provided on the main body, the receiving cavity being used to accommodate a pre-set target type power module, the outer surface of the main body matching the power installation compartment of a pre-set target type electrical equipment; an input interface provided inside the receiving cavity of the main body, used to match and connect with the power supply port of the pre-set target type power module; an output interface provided on the outer surface of the main body, used to match and connect with the power receiving port of the pre-set target type electrical equipment; part or all of the pins of the input interface and the output interface are matched through a pre-set conversion rule, and an electrical connection is provided between the matched pins.

[0038] In an embodiment, as Figure 4 、 Figure 5 、 Figure 6 , the accommodating cavity is used to accommodate the installation of the CRPS power supply module.

[0039] In an embodiment, the outer surface of the main body matches the power supply installation compartment of the target blade server.

[0040] In an embodiment, part or all of the pins of the input interface and the output interface are matched through a preset conversion rule, and an electrical connection is provided between the matched pins, including: connecting the input interface and the output interface through the I2C channel. Part or all of the signal pins are matched according to the preset conversion rule.

[0041] The preset conversion rule can be adjusted according to the definition rule of the power supply pins before and after conversion. Taking the CRPS power supply before conversion and the PSR-12A standard power supply after conversion as an example, the following Table 1 shows the conversion relationship between the pins. Among them, part or all of the signal pins are converted through the I2C signal channel

[0042]

[0043]

[0044] Table 1

[0045] In the above embodiment, further, in the design of the adapter board, the signal adaptation corresponding relationship between the CRPS output connector interface and the 3000W power supply output connector interface is listed in detail. This includes the conversion processing of ground (GND), +12V power supply, I2C data line, I2C clock line, PSON control signal, SMBALERT signal, ReturnSense signal, +12VRemoteSense signal, etc. This accurate signal adaptation ensures that the electrical connection between the power supply and the blade server is fully compatible.

[0046] In terms of single board process, considering that there is a height difference of 1.08mm between the two connectors, which causes them to be unable to be normally docked at the same time, this scheme adds a 1mm thick PCB dummy board on the left connector to raise the left connector, ensuring that the left and right connectors can be normally docked.

[0047] The newly introduced titanium gold power supply provides two address lines A0 and A1 directly connected to the middle backboard, while the A2 address line is set to 0, and the middle backboard end is directly grounded, and no processing is done on the adapter board. This configuration simplifies address management while ensuring system compatibility.

[0048] In order to ensure the stability and reliability of the signal, the pull-up / pull-down resistance value configuration on the signal line is also specified in detail, including the resistance value configuration of A0, A1 and A2, which refers to the standard inside H3C system, ensuring the stability of the signal.

[0049] Considering the heat generated by the power supply in operation, the adapter plate is configured with a heat dissipation scheme that does not hinder the ventilation and heat dissipation of the power supply, ensuring the stable operation of the system. It ensures that the power supply can maintain a good temperature state even under high load conditions, prolongs the service life and improves the reliability.

[0050] In one embodiment, as Figure 7 、 Figure 8 The present specification also provides a blade server, which comprises a plurality of power supply installation compartments, and the power supply installation compartments are provided with the power supply adapter device according to any one of the technical solutions.

[0051] In one embodiment, the present specification also provides a power utilization equipment, which comprises a power supply installation compartment, and the power supply installation compartment is provided with the power supply adapter device according to the technical solution, and the power supply installation compartment is provided with a power receiving port, which is matched and connected with the output interface of the power supply adapter device according to the technical solution.

[0052] The present specification also provides a power supply module, which is installed in the accommodating cavity of the power supply adapter device according to the technical solution, and the power supply module comprises a power supply port, which is matched and connected with the input interface of the power supply adapter device.

[0053] In the embodiments of the present specification, the description of direction words such as upper end surface, lower end surface, end portion, etc. is made with reference to the drawings.
