Description
Technical field
The utility model relates to a kind of technical field of refrigerating devices, specifically a kind of communication machine room distributed heat management devices.
Background technology
Growing along with mechanics of communication, the integrated degree of electronic device is more and more higher, and the equipment heating amount is increasing, and the requirement of humiture also improves gradually.In view of information technoloy equipment caloric value in the machine room large; the thermal environment of equipment within machine cabinet all has a great impact life-span and the operational reliability of electronic device; therefore need to strictly control space temperature in hot localised points in the rack and the machine room, prevent overheated the burning of shutdown or electronic device of causing.When there is hot localised points in data center apparatus, generally adopt the mode that strengthens air output and reduce wind pushing temperature, eliminate hot localised points, increased the air conditioner in machine room energy consumption.Need preferably air current composition in the machine room simultaneously, guarantee the uniformity of temperature.
The method of communication machine room distributed heat management is to utilize hot pipe technique that the communication apparatus part is lowered the temperature, and utilizes simultaneously the technology of blowing under the air conditioner in machine room floor and the technology of upper return air, reasonably organizes air-flow to eliminate the characteristic of non-uniform temperature in the communication machine room.The method had both guaranteed communication apparatus normal operation, again extension device service life.This device is embedded into heat exchange of heat pipe in the rack, by placing heat pipe in the high position of caloric value, and its heat is discharged into the rack outside.Air conditioner in machine room is blown by under the floor, takes away the heat of communication apparatus and the heat that heat pipe gives off, and gets back to air conditioner in machine room by top return air again and forms a circulation.The application of the method has reduced hot localised points, has reduced the non-uniform temperature in the communication machine room, has guaranteed the normal operation of communication apparatus.
Through the prior art literature search is found, China's Granted publication number is: CN2001191048Y, name is called: the air-supply heat sink of computer, the high heat-producing device of communication machine room, introduced the air-supply heat sink of a kind of computer, the high heat-producing device of communication machine room, comprise air conditioner, air main, the some terminal ajutages that are communicated with air main, wherein have in the part terminal ajutage blower fan is housed, its installation site and air outlet are facing to the disadvantageous computer of golf calorific value or position or communication apparatus.This patent can be carried out quantitatively the disadvantageous computer of high heat-producing device or position or communication apparatus, the cold airflow work feed of level pressure, location, simultaneously also can be with respect to favourable computer or the communication apparatus of common caloric value or position, can also keeping with respect to interior space mean air flow, therefore can effectively reduce energy consumption, the assurance all devices can both be worked in its normal operation circumstances temperature.Its structure and characteristics can't be eliminated hot localised points in the rack, also can't guarantee air-flow in the machine room and the uniformity of temperature.
Find through retrieval again, Chinese patent application number is: CN201110273366.2, name is called: a kind of energy saver that is applicable to accurate control air conditioner in machine room, introduced a kind of energy saver that is applicable to accurate control air conditioner in machine room, this utility model discloses a kind of energy saver that is applicable to accurate control air conditioner in machine room, is comprised of refrigerant compression unit, hot heat exchange of heat pipe, air-valve, blower fan, air channel and the electric-control system that wets control device, loop heat-pipe apparatus, isolation air channel.In transition season and winter, open and close by the electric-control system autocontrol valve, allow room air pass through isolation air channel in the room, there is outdoor cold air process in isolation air channel outside the room, by the layout of intermediate isolating air channel heat exchange of heat pipe, utilize the cold of extraneous air to cool off the interior air of machine room.Advancing on the line arrangement of air draft, the same isolation air channel heat exchange of heat pipe that utilizes, recovery section air draft cold when summer condition is used for the new wind of precooling.The loop heat-pipe apparatus of arranging before and after the evaporimeter can the electrically heated energy consumption of recovery section, has saved energy.Its structure and characteristics does not adopt the method for hot localised points control, can't guarantee the stable operation of the large device security of caloric value, does not guarantee the uniformity of air temperature and current in the machine room by rational air current composition yet.
Present most of Air Conditioning Facilities adopt the whole cooling profiles of top air-supply more, can't avoid the too high information technoloy equipment fluctuation of service that causes the caloric value height to cause of local temperature of high heat generation density information technoloy equipment.The direction of simultaneously top air-supply and hot pressing is fully opposite, and cold wind need to overcome blast and adopt blow farther, and adopts air conditioner in machine room bottom return air to make relatively cold air get back to again evaporimeter, has lost the part cold.Therefore adopt the mode of floor blowing and top return air, can make thermal current get back to air conditioner in machine room at the top, effectively got rid of the heat of information technoloy equipment.
