Description
Technical field
What the present invention relates to is a kind of device of computer to dissipate heat technical field, specifically is a kind of separate type microchannel heat pipe air-conditioning system with evaporative condenser.
Background technology
Computer or communication station internal calorific power are big, can reach 200-1000W/m
2, making that the air-conditioning system load is very high, corresponding consumed power is many especially.Common communication station power consumption 51 in a year according to investigations, 000kWh, air-conditioning power consumption 11627kWh, 1/4 of total power consumption that accounts for.Therefore how under the situation that satisfies the equipment instructions for use, the energy consumption that effectively reduces the air-conditioning system of computer or communication station is the major issue that air conditioner industry faces.In the prior art, the approach that reduces communication station air-conditioning system energy consumption mainly contains to be optimized the air blow and return mode, utilizes natural cooling source mode, optimal control technology etc., but all exist not obvious such as maintenance cost height, energy-saving effect, have a shortcoming such as security hidden danger.The appearance of separate heat pipe has solved this problem, and separate heat pipe is to utilize refrigerant air-liquid two-phase density contrast, allows a kind of radiating mode of its Natural Circulation, and contribution is arranged when indoor temperature is higher than environment temperature.Because indoor and outdoor gas does not mix mutually, can not worsen indoor environment, 1 year most of season contribution is arranged all, can effectively reduce maintenance cost and potential safety hazard, and realize low energy consumption.
Find through literature search prior art, Chinese patent literature number: CN201311219Y, this technology discloses a kind of heat extraction device for equipment room that adopts the separate heat pipe countercurrent flow, it is characterized in that evaporimeter and condenser all contain the above heat exchanger of at least two groups, the bottom of every group of heat exchanger is communicated with every group of heat exchanger top in the evaporimeter by gas-liquid tube connector respectively in the condenser, and it is corresponding one by one, the inner air and outer air adverse current heat exchanger structure of forming from the formula heat pipe by multicomponent, this device effectively reduces energy consumption, but multi-group heat exchanger causes this patent structure complexity, consumable material increases, and cost and maintenance cost increase, and are unfavorable for promoting the use of.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of separate type microchannel heat pipe air-conditioning system is provided, use the separate heat pipe system of evaporative condenser and microchannel type heat exchanger composition and traditional air-conditioning system, two system's not involvements mutually, all there was contribution in separate heat pipe system wherein 1 year most of season, the operating temperature at the machine station of can effectively keeping in communication, and realize low energy consumption, its cycle fluid is a cold-producing medium, and cost is low and effective.The operation principle of separate heat pipe is that cold-producing medium external heat release in condenser becomes liquid, under the effect of gravity, enter in the evaporimeter, in evaporimeter, become gas from indoor heat absorption, under the effect of density contrast, enter in the condenser, finish circulation, realize heat is transferred to outdoor function from indoor.Then open air-conditioning system in the weather of sweltering heat in summer, two systems work simultaneously, the operating temperature at the machine station of can effectively keeping in communication, and the separate heat pipe system can share the load of air-conditioning system, cuts down the consumption of energy.
The present invention is achieved by the following technical solutions, the present invention includes: separate type micro channel heat guard system and air-conditioning system, wherein:
Separate type micro channel heat guard system by be positioned at indoor micro-channel evaporator, outdoor evaporative condenser, gas valve and Liquid valve constitutes.
Air-conditioning system is made of choke valve, evaporimeter, condenser and compressor, wherein: compressor is connected with air-conditioning condenser, choke valve and A/C evaporator respectively and is constituted air-conditioning system, the micro-channel evaporator of heat pipe and A/C evaporator are positioned at indoor, and evaporative condenser, air-conditioning condenser and compressor are positioned at outdoor.
Described separate type micro channel heat guard system is provided with gas valve and Liquid valve, wherein: gas valve is series at the output of indoor micro-channel evaporator with between the input of outdoor condenser, and Liquid valve is series at the output of outdoor evaporative condenser with between the input of indoor micro-channel evaporator.
Described micro-channel evaporator is the microchannel type heat exchanger of band blower fan.
Described heat pipe micro-channel evaporator is level or tilts to place.
The present invention's advantage compared with prior art comprises:
1) the heat transfer efficiency height, improve air-conditioning EER, the weight of refrigeration system is reduced, material alleviates, uses aluminum to replace the charging amount of expensive copper product, minimizing cold-producing medium.So this patent uses micro-channel heat exchanger to substitute the heat exchanger of copper pipe aluminium fin-type in separate heat pipe, purpose is to reduce cost on the basis of strengthening heat exchange.In experimental study, under identical operating mode and condition, the heat exchange amount of micro-channel heat exchanger can reach 4200W, and the heat exchanger of copper tube aluminum formula has only 2600W.This shows that the heat exchange amount of micro-channel heat exchanger can be far longer than the pipe type heat exchanger under the same case, thereby helps the performance of hot-pipe system performance more.
2) the radiating efficiency height, refrigerating capacity is big, degree of supercooling is big.Because evaporative condenser can provide the degree of supercooling bigger than common air cooled condenser, when worst hot case, the heat pipe range of operation is enlarged, improve the performance of heat pipe.Evaporative condenser can make separate type microchannel heat pipe range of operation become big, better effects if.The condensation temperature of evaporative condenser so just can better be brought into play the effect of separate heat pipe than low 8～11 degree of air cooled condenser in the sweltering heat in summer, guarantee the efficient operation of heat pipe.
3) the separate heat pipe system of microchannel type heat exchanger and evaporative condenser composition and traditional air-conditioning system, two system's not involvements mutually.All there was contribution in the separate heat pipe system 1 year most of season, can effectively the keep in communication operating temperature at machine station, and realization low energy consumption, its cycle fluid is a cold-producing medium, low price and effective, and indoor and outdoor gas does not mix mutually, can not worsen indoor environment, simple in structure, can effectively reduce maintenance cost and potential safety hazard, consumable material makes that less production cost is low simultaneously.The windage of micro-channel heat exchanger is little, can effectively reduce energy loss.Evaporative condenser has good heat dissipation effect, efficient height, advantage such as radiating rate is fast.Then open air-conditioning system in the weather of sweltering heat in summer simultaneously, two systems work simultaneously, the operating temperature at the machine station of can effectively keeping in communication, and the separate heat pipe system can share the load of air-conditioning system, cuts down the consumption of energy.
