technical field

The utility model relates to a server cooling device, in particular to an intelligent blade server cooling cabinet with energy-saving design.

Background technique

In recent years, rack installation has become the mainstream in the system configuration, storage, and installation of information processing devices such as servers. The cabinet installation method is to stack devices with various functions in the cabinet formed according to specific specifications. The cabinet installation method has the advantages of free selection and configuration of various devices, and the system structure is flexible, the scalability is good, and the overall system footprint can be reduced. advantages such as area.

Traditional server cabinets are simple in structure, just mount multiple server components in the cabinet, adopt forced air cooling, and only install ordinary fans in the cabinet for ventilation and heat dissipation of the cabinet. At present, with the emergence of blade servers with higher performance and faster processing speed, since the blade servers are densely inserted into the casing and put into the cabinet, its central processing unit (CPU) will generate a lot of heat, thus The concentrated heat source in the cabinet is too large. Relying solely on the cooling fan of the server itself and the fan on the traditional server cabinet cannot discharge heat in a timely manner, and even the discharged heat causes the overall temperature of the computer room environment to rise. The forced air cooling method is not conducive to the operation of the server. Therefore, it is necessary to provide a server cooling cabinet that can effectively cool down, solve the heat dissipation problem of the blade server and has an energy-saving function.

Utility model content

The technical problem to be solved by the utility model is to provide an energy-saving server cooling cabinet, which can overcome the problem of only relying on fan heat dissipation or forced cooling by a refrigerator, and adopts control technology to achieve cooling of the server cabinet between heat dissipation and refrigeration. purpose, and at the same time have energy-saving effects.

In order to solve the above technical problems, the utility model provides the following technical solutions: energy-saving server cooling cabinet, including: a cabinet body; a fan installed in the cabinet body; An intelligent control unit, a linkage controller and a wind temperature sensor are arranged inside the cabinet body.

A further technical solution is that the intelligent control unit is electrically connected with the air temperature sensor, and the linkage controller is electrically connected with the fan and the main unit of the indoor air conditioner.

A further technical solution is that an evaporator coil and an evaporator fan are arranged on the heat exchange refrigeration back plate.

According to the technical solution of the utility model, the unique control device is used to intelligently start the high-efficiency fan, and the compressor is turned off for refrigeration in good time, and through the linkage control between the fan and the main unit of the indoor air conditioner, sufficient air volume is obtained to achieve the best cooling effect, thereby It has achieved successful energy-saving benefits, especially for the centralized heat source generated by the blade server. It has an all-round solution ability. It can not only provide better heat dissipation performance, but also directly overcome the high temperature generated by the server through the cooling mechanism to achieve cooling in the cabinet.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Detailed ways

Referring to Figures 1 to 3, the utility model includes a cabinet body 1, a fan 2 located at the bottom of the cabinet body 1, a heat exchange refrigeration backplane 3, an intelligent control unit 4, a linkage controller 5 and an air temperature sensor (not shown). Several blade servers (not shown) can be placed in the cabinet body 1 . The heat exchanging cooling backplane 3 is arranged on the rear side of the cabinet body 1 , on which an evaporator coil 30 , a compressor 31 and an evaporator fan 32 are arranged. In this embodiment, the heat exchange and refrigeration backplane 3 is movably connected to the cabinet body 1, and the heat exchange and refrigeration backplane 3 is pivotally arranged on the back of the cabinet body 1, so that the heat exchange and refrigeration backplane 3 can be positioned relative to the cabinet. The main body 1 is opened/closed, which is convenient for maintenance personnel to maintain. The intelligent control unit 4 , the linkage controller 5 and the air temperature sensor are all arranged in the cabinet body 1 . The intelligent control unit 4 of the present utility model decides whether to start the refrigeration mechanism according to the signal from the air outlet temperature sensor, the intelligent control unit 4 is connected with the electric signal of the air temperature sensor, and the linkage controller 5 is connected with the fan 2 and the room in the room where the server cabinet is placed. Air conditioner host electrical signal connection.

The working process of the present utility model is further described below:

When the cooling cabinet of the utility model is in use, the fan 2 placed at the bottom of the cabinet body 1 starts to directly absorb the cold air supplied by the main unit of the indoor air conditioner, and inject the cold air into the cabinet body 1, and at the same time evaporate through the heat exchange refrigeration back plate 3 The air blower fan 32 is used to effectively discharge the heat emitted by the server in the cabinet body 1, and at the same time bring cold air from the outside of the cabinet body 1; Connect with the electrical signal of the main unit of the indoor air conditioner;

When the heat in the cabinet body 1 continues to increase, so that the temperature of the hot air discharged by the fan 2 is higher than the set temperature, the intelligent control unit 4 will automatically turn on the power of the compressor 31 on the heat exchange refrigeration backplane 3 to start the heat exchange refrigeration The refrigerator on the backplane 3 works to directly reduce the heat in the cabinet body 1; the intelligent control unit 4 is connected to the power switch of the compressor 31 on the heat exchange refrigeration backplane 3 with electrical signals;

When the intelligent control unit 4 detects that the outlet air temperature in the cabinet body 1 drops below the set temperature through the air temperature sensor, the compressor 31 on the heat exchange refrigeration backplane 3 is stopped, and the fan 2 is restarted to dissipate heat. Achieve energy saving benefits.

In addition, the compressor 31 on the heat exchange and refrigeration backplane 3 of the present invention can also be arranged outside the cabinet body 1, and the heat exchange and refrigeration backplane 3 can also be installed on the back of the cabinet body 1 or as required On the side of the cabinet body 1.

As mentioned above, when the temperature inside the cabinet body 1 is lower than the set temperature, the linkage controller 5 controls only the fan 2 to provide large air volume for heat dissipation; when the outlet air temperature is higher than the set temperature, the compressor is started through the intelligent control unit 4 31 refrigeration, the temperature in the cabinet body 1 is directly lowered. In addition, in order to ensure that the fan 2 can provide sufficient air volume for heat dissipation, the linkage controller 5 set between the fan 2 and the indoor air conditioner can force the air conditioner to provide a cold source, and the linkage controller 5 is connected to the fan 2 and the indoor air conditioner by electrical signals. The utility model takes into account the control of the temperature inside the cabinet body and the temperature in the environment, effectively maintains the safe operation of the computer, and greatly improves the energy-saving benefit through its intelligent operation.
