Description
Technical field
The present invention relates to heat exchange cooling system, especially a kind of heat-exchanger rig suitable for communication base station cabinet.
Background technology
As communications industry telecommunications room and communication base station enter the communication cabinet in 5G epoch, electronic component in its cabinet
Under the premise of power consumption is drastically elevated, how electronic component is in stable operating status, its important necessary requirement in cabinet
One of be that the thermal control of the inside and outside environment of cabinet reaches stable state；Therefore the reliability of the temperature-controlling system in cabinet inner chamber body space
And its intelligence of temperature control process similarly can greatly influence the reinforcing and performance of communication cabinet function.Therefore how reliable,
Efficiently, a variety of failures and hidden danger that inexpensive solution cabinet, large data center and server are brought because thermal management is unstable；
This is that telecom operators are asked for telecommunications room and without what the normal operations such as ventilated type telecommunication cabinet, data center were paid close attention to the most
Topic.
Its service of the current world, home communications cabinet, server cabinet, high-end power control cabinet and large data center control system
Temperature is excessive in device, is current communication base station, high-end power control cabinet and data center's common problem；Since data center takes
Temperature is excessive in business device causes server to be delayed machine, and equally, environment temperature is excessive to cause in-cabinet temperature equilibrium state tropical island effect to add
Play can seriously affect the continuity and reliability of communication.Cause in-cabinet temperature is excessive there are two reasons:One is due to server
Quantity be continuously increased so that space is more and more nervous in data center；Second, have no alternative but put in cabinet more and more
Server；Meanwhile the developing direction of computer is that volume is less and less, more and more compacter at present, particularly 5G and blade type clothes
It is engaged in the appearance of device, causes temperature in communication cabinet inner chamber body and data center's cabinet considerably beyond computer chip and integrated mould
The scope that block element can be born.It is common in order to solve telecommunications room, communication base station and the thermal management issues of equipment enclosure
Temperature control method is no lack of machine cabinet air-conditioner series, heat exchanger series, integrated the machine cabinet air-conditioner series, the air-conditioning that have heat exchanger
Door control cabinet series, digital variable multi-joint technology air-conditioning system, liquid cooling system, Ground Coupled Heat Pump be serial, air-air cabinet door is inlayed
The communication cabinets such as formula cooling system often use temperature control product；But its energy consumption of such type of cooling accounts for base station is always consumed more than 40%,
Particularly communications industry will enter space power consumption in its cabinet of 5G epoch and significantly rise, therefore, reliable energy saving cooling mould
Formula has been widely considered to be a kind of only selection of communication base station, communication cabinet and data center's thermal design.
Domestic at present, external communication cabinet inner chamber body space is substantially generally the work with compressor using the pattern of cooling
Industry is by the use of air-conditioning or by the use of heat pipe as the air-cooled pattern of heat delivery vehicle, its former high energy consumption, and moving component causes poor reliability more；
And the latter particularly 4G and it is following be also that for power consumption in 2400W, domestic and international industry is mostly using air-air stacked flat in cabinet
Tabular Heat transmission core radiates, and power consumption is considerably beyond power consumption in 4G cabinets in 5G cabinets, using air-air even additional half
Conductor freezes, and is still difficult reply heat dissipation load, while not only own cost is high and energy consumption is big for semiconductor refrigerating, it is often more important that
There are still the problems such as reliability；And in blade server using point-to-point pipe direct cooling heat or liquid it is cold, field of Communications again very
Difficulty receives such scheme, worry liquid just in case leakage can bringing on a disaster property stop ruining machine failure.
To sum up analyze, electronics industry and the communications industry in 5G epoch, large data center etc. will be entered be required to cooling system
Unite reliability, controllability, stability and the reasonability of low manufacture cost and operating cost of its cooling equipment, therefore with logical
Interrogate the demand of industry particularly 5G communication cabinets, its more reliable, more cheap, more energy efficient innovative cabinet heat exchanger product
Seem increasingly urgent.
