Description
Technical field
The utility model relates to a kind of energy-conservation heat-exchanger rig, and particularly a kind of machine room or base station etc. need the energy-conservation heat-exchanger rig of heat radiation.
Background technology
Along with the development of telecommunications, the particularly mushroom development of 3G business, machine room and base station occur in a large number.Mostly equipment in the machine room is heat dissipation equipment, continues the bulk storage heat under normal operation, again because the equipment operation needs suitable temperature range, so in order to guarantee the temperature in the machine room, must discharge machine room to the heating of equipment.The mode of heat radiation commonly used mainly contains two kinds: a kind ofly be air-conditioning temperature-reducing, another kind of for introducing new air heat-exchange, the high temperature air that outdoor lower surrounding air is introduced directly into inside and inside by simple filtering mixes lowers the temperature.Air-conditioning temperature-reducing is under the situation of isolating fully in the indoor and outdoor, and the circulation by cold-producing medium leads out indoor heat.
The major defect that uses air-conditioning to lower the temperature is the energy consumption height, is under 1: 3 the situation in Energy Efficiency Ratio, and the heat of the 7KW that shed will consume the electric energy of 2.3KW.Next is the fault rate height, because the part of air-conditioning the inside is many, and critical piece is moving components such as compressor, damages easily.Introducing the main shortcoming of new air heat-exchange need introduce outdoor air in the machine room; because there is a large amount of dusts in outdoor air; simultaneously because the humidity of outdoor air is high sometimes; sometimes low; directly introducing to make indoor humidity reach outdoor level very soon; so usually can surpass the humidity range that equipment can bear, cause device damage.In the low and unreasonable life-span that all can reduce equipment greatly of humidity of environment cleanliness, this also is to introduce this mode of new air heat-exchange to never have widely accepted main cause.
A kind of heat exchange energy saver is disclosed among the Chinese patent literature CN2849538Y, this heat-exchanger rig is in order to make indoor air suction inlet and outlet in the same side, adopt two cross-current heat exchangers to form the air channel, two square cross-current heat exchangers are in series along diagonal, leg-of-mutton air channel is arranged between the cross-current heat exchanger, wherein the indoor blower fan is connected with first air channel of cross-current heat exchanger, and is connected with first air channel of heat exchanger; The outside blower fan is connected with second air channel of heat exchanger, and is connected with second air channel of heat exchanger.Though the square cross-current heat exchanger of separate unit of this scheme solution can't realize that room air is in the problem of homonymy turnover heat exchanger while outdoor air at opposite side turnover heat exchanger as can be seen, but because the angle in heat exchange air channel is 90 degree in the cross-current heat exchanger, must cause in an air channel reduction or rising along with air themperature, its for the exchange capability of heat in another one air channel all along with the flow direction of air reduces; In other words, for the difference of another air channel existence, can cause the difference of exchange capability of heat owing to the position, air channel.The heat exchange that is whole heat exchanger is uneven, and the wind-warm syndrome of air outlet also is uneven, thereby has reduced the heat exchange efficiency of cross-current heat exchanger.By side sectional view, we can also find that the air channel has taken the only about half of space of heat exchanger main body, and identical like this heat exchange area (heat exchange amount) needs bigger volume to satisfy.Simultaneously, because its heat exchange efficiency is relatively low, so can further increase the size that is taken up space.In addition, also exist heat exchanger fixing insecure, carry, fall shortcomings such as easy deformation.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, volume is little, easy for installation, energy-efficient, reliability is high, the energy-conservation heat-exchanger rig of long service life, machine room that indoor cleanliness factor is high, to overcome weak point of the prior art.
Press the energy-conservation heat-exchanger rig of a kind of machine room of this purpose design, comprise the heat exchanger that is arranged on indoor blower fan, the outside blower fan in the casing and is used for gas-gas heat exchange, the outdoor air heat exchange that the indoor air that the indoor blower fan drives drives by heat exchanger and outside blower fan, it is characterized in that heat exchanger is dull and stereotyped stacked, and the heat exchange air channel, indoor that is positioned at casing parallels with heat exchange air channel, outside, and the indoor air is opposite with the flow direction of outdoor air.
Be respectively arranged with the ripple heat exchanger fin that is used to strengthen heat exchange in heat exchange air channel, described indoor and the heat exchange air channel, outside.L-shaped or the U-shaped in heat exchange air channel, indoor and heat exchange air channel, outside, heat exchanger is square or rhombus.Perhaps indoor heat exchange air channel and heat exchange air channel, outside is combined as L-L, L-U, U-L or U-U.Heat exchanger adopts combining of aluminium and aluminium alloy, copper and copper alloy, paper, plastics or they.
Described indoor blower fan and outside blower fan are respectively axial flow blower, flow-mixing blower fan or centrifugal blower.Indoor blower fan and outside blower fan are respectively more than one.The indoor blower fan is arranged on the air draught side of heat exchanger, and the outside blower fan is arranged on the air draft side of heat exchanger.
The utility model both can the indoor air circulation be set to down the row of sucting, the outdoor air circulation is set to inhale row down, also the indoor air circulation can be adopted to go up and inhale row down, the row of sucting under the outdoor air circulation is adopted, thus have bigger flexibility.
Running device of the present utility model is few, and the chance that breaks down is low, can reduce the cycle of equipment routing inspection and maintenance for remote districts; Its efficiency height produces same cold or takes away same heat, and the electric energy that is consumed is far below adopting air conditioner refrigerating.
Heat exchanger heat exchange efficiency height in the utility model, volume is little, adopts countercurrent flow, and the indoor-outdoor air heat exchange is abundant; Only to the indoor cold that provides, outdoor dust and humidity can not brought into indoor, thereby guarantee indoor cleanliness factor and humidity; Whole energy-conservation heat-exchanger rig convenient and flexible installation is easy to arrange.
