Description

Technical Field

[0001] The utility model belongs to the technical field of servers, and specifically relates to an outdoor edge server. Background Art

[0002] A server is a high-performance computer that provides various services in a network environment. Its main functions include receiving, processing, and responding to requests from clients, and providing services in aspects such as files, databases, applications, and communications for network users.

[0003] Server heat dissipation is a crucial issue in data centers and high-performance computing environments. With the improvement of server performance and the increase in integration, the heat dissipation demand is also increasing day by day. Currently, there are mainly two heat dissipation methods: air-cooled heat dissipation and liquid-cooled heat dissipation. Air-cooled heat dissipation has relatively low cost and mature technology, but the air-cooled heat dissipation efficiency is limited, especially in a high-density server environment or in a completely enclosed chassis, it is not very applicable; liquid-cooled heat dissipation absorbs and transfers heat through a liquid medium (such as water or coolant), and cold plate liquid cooling and immersion liquid cooling are two common liquid-cooled solutions.

[0004] With the development of technologies such as the Internet of Things, 5G, and intelligent transportation, edge computing has gradually become an important means to process massive data and reduce network latency. As the core device of edge computing, edge servers need to be deployed in various outdoor environments. However, factors such as high temperature, dust, and humidity in outdoor environments pose severe challenges to the stable operation of servers. The existing air-cooled heat dissipation system has low heat dissipation efficiency in high-temperature environments and cannot meet the requirements of the sealing protection level, while the traditional liquid-cooled heat dissipation system is relatively large in volume and inconvenient to deploy. Summary of the Utility Model

[0005] To solve the problem that the current air-cooled heat dissipation and liquid-cooled heat dissipation are not very applicable to outdoor edge servers, the utility model provides an outdoor edge server.

[0006] The utility model is realized through the following technical solutions:

[0007] An outdoor edge server includes a plate-fin radiator, a chassis with an opening at the front, and a chassis front cover that seals and fastens the front opening of the chassis; an installation groove is formed in the middle of the chassis front cover, a second cold plate that is fitted and installed with the installation groove is adhesively installed in the middle of the back of the plate-fin radiator, and the periphery of the back of the plate-fin radiator is hermetically installed in contact with the chassis front cover; a cooling fan capable of blowing air to dissipate heat from the plate-fin radiator is installed at the front of the chassis front cover; a flow pump and a first cold plate capable of being adhesively installed with server heat dissipation components are arranged inside the chassis, and the second cold plate, the flow pump, and the first cold plate are connected in a closed loop at the head and tail through pipelines.

[0008] A further improvement of the present utility model is that the flow pump is positioned and installed inside the front cover of the chassis through a mounting bracket.

[0009] A further improvement of the present utility model is that a solenoid valve is installed at the outlet end of the flow pump.

[0010] A further improvement of the present utility model is that a number of the first cold plates are arranged in parallel, and a solenoid valve is installed at one end of each of the first cold plates.

[0011] A further improvement of the present utility model is that a heat-conducting pad for press-fitting and sealing with the front cover of the chassis is covered around the back of the plate-fin radiator.

[0012] A further improvement of the present utility model is that the heat-conducting pad is a silica gel heat-conducting pad.

[0013] A further improvement of the present utility model is that the fins of the plate-fin radiator are arranged vertically; a brim capable of shielding and protecting the plate-fin radiator is connected and installed on the front side of the upper part of the front cover of the chassis; a fan bracket is connected and installed on the front side of the bottom of the front cover of the chassis, and a number of fan bins capable of positioning and installing the cooling fans are provided on the fan bracket; the upper part of the fan bin is open, and a number of ventilation holes are provided at the bottom of the fan bin.

[0014] A further improvement of the present utility model is that a radiator cover capable of surrounding the front side and the left and right sides of the plate-fin radiator is buckled and installed on the front side of the front cover of the chassis.

[0015] A further improvement of the present utility model is that the front part of the fan bin is open, and a cover plate capable of sealing and buckling the front opening of the fan bin is detachably installed on the fan bracket.

[0016] A further improvement of the present utility model is that a sealing ring is provided between the front cover of the chassis and the chassis.

[0017] It can be seen from the above technical solutions that the beneficial effects of the present utility model are:

[0018] The first cold plate is installed in close contact with the internal heat dissipation components of the server. A coolant is filled in the closed loop formed by the first cold plate, the second cold plate and the flow pump. The flow pump provides the circulating power for the coolant, and the heat absorbed by the first cold plate is transferred to the second cold plate through the coolant. The plate-fin radiator conducts the heat in the second cold plate, and the cooling fan blows air to dissipate heat from the plate-fin radiator. Thus, good cooling and heat dissipation of the internal components of the outdoor edge server can be achieved, ensuring the reliable and stable operation of the outdoor edge server. Moreover, the overall outdoor edge server is of a fully enclosed structure, which can effectively ensure the sealing protection level during outdoor operation and ensure the reliable and stable operation of the outdoor edge server. The plate-fin radiator is integrally arranged with the outdoor edge server, with a small volume and a small footprint, ensuring the convenience and flexibility of the arrangement.
