Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of server room heat removal, and relates to a heat pipe backboard air conditioner, in particular to a heat pipe backboard air conditioner with a distributed fire-fighting device, which is suitable for traditional server rooms and data centers, can timely and effectively remove the heat of the servers in the cabinet to the server room, and can reduce energy consumption; at the same time, the modular precise fire-fighting protection is provided for each server cabinet, the response is rapid, and the maintenance is convenient. BACKGROUND

[0002] At present, the power density of supercomputing and intelligent computing scenes is increasing day by day, the fire load is large, the value of equipment and property is increasingly expensive, the fire risk and loss are great, and in the existing fire-fighting design of server rooms and data centers, a room-level smoke and temperature sensing linkage automatic fire extinguishing system is mostly used. The control logic of the system starts fire-fighting through smoke sensing and temperature sensing, there is a problem of delay in fire extinguishing start, and the system cannot be accurately positioned, has a large influence range after starting, and is not conducive to the continuous operation of the server room. It is an urgent need to set a precise fire-fighting module for important parts and high fire risk parts to detect early and extinguish fire early, control the fire in the local independent equipment, and do not affect the normal work of other equipment.

[0003] At present, in the field of precise fire-fighting of server rooms, a rack type fire-fighting module is used. The module is a cabinet fire-fighting product (such as a standard 2U) produced based on taking a fire-fighting product as a micro-module data center cabinet standard part. The module can be embedded in a server cabinet, and when a fire occurs, the module can realize automatic fire extinguishing and report the fire alarm to a monitoring system. There is also a top type precise fire-fighting module that places a fire-fighting module on the top of a cabinet to realize precise fire-fighting. These two types of precise fire-fighting of server rooms both realize early and precise fire extinguishing, but need to occupy the space in the cabinet or affect the wiring space on the top of the cabinet.

[0004] In addition to the fire-fighting system, the heat dissipation of the server room is also an important technical challenge. With the continuous increase of the power density of servers, the traditional room-level air conditioning refrigeration method has been difficult to meet the heat dissipation needs of high-density server rooms. The traditional heat dissipation method usually uses air conditioning for room-level refrigeration, which leads to high energy consumption of the air conditioning terminal, low heat dissipation efficiency, and difficulty in realizing precise temperature control of the server cabinet.

[0005] In summary, the existing fire-fighting system of server rooms generally has problems of slow response speed, low positioning accuracy, and large influence range, and the existing rack type and top type precise fire-fighting modules still have problems of occupying cabinet space or affecting the top wiring, etc. At the same time, the traditional heat dissipation method has low efficiency and high energy consumption, and is difficult to meet the needs of high-density server rooms. Therefore, how to develop a server room solution that can efficiently dissipate heat and realize precise fire-fighting without occupying cabinet space and is easy to maintain is a technical problem to be solved.
