Description
Technical field
The present invention relates to a kind of industrial cabinet air conditioner, relate to specifically the anti-sidewall installation cabinet air-conditioning that blows water of a kind of upper air-out.
Background technology
Along with wide variety of equipment, particularly electrical equipment and electronic equipment, more and more higher to the requirement of the clean level of surrounding air and temperature stability, cabinet air conditioner has obtained using more and more widely.Consider the custom of the common inlet air flow path of interior of equipment cabinet, inner installation and layout, at present, the cabinet of sidewall installation both at home and abroad air-conditioning has all adopted in evaporation side the configuration mode that sucks hot-air, bottom discharge cold air from top.And, in order to make the flow path of cold air in rack long as far as possible, manufacturer designs the air inlet of evaporation side suction hot-air in uppermost position, and an air outlet of discharging cold air is designed in nethermost position.International prestige figure and safe two companies of running quickly, the sidewall installation cabinet air-conditioning of the companies such as Hai Lite, the Lei Zike of China and Lei Bo is all like this, in the evaporation side of heat absorption, air flows through from top to bottom at evaporator surface.Because in refrigeration, the surface temperature of evaporimeter is all very low, so evaporator surface can constantly produce condensed water.Top-down air accelerates the motion from top to bottom of evaporator surface condensed water, even condensed water can be blown to interior of equipment cabinet.Fig. 2 is the air-flow direction schematic diagram that uses the sidewall installation cabinet air-conditioning evaporation side of prior art.In rack, air is forced to flow through the components and parts of heating from bottom to top, the hot-air that is gathered in rack top is sucked into sidewall installation cabinet air-conditioning, is blown to the rack bottom by the air outlet from the air-conditioning bottom from top to bottom after the evaporimeter of low temperature, forms flow circuit one time.In the circulation of such Air Flow, powerful air-out meeting blows to interior of equipment cabinet to the condensed water in drippage process, causes the accident.
The equipment of interior of equipment cabinet all can not get wet, and Chinese invention patent 200110134729.8 has just illustrated in the background technology analysis that sidewall installation cabinet air-conditioning has " potential safety hazard greatly ".Chinese invention patent 201010570348.6 has been invented the method for " by self pressure relief vent structure automatically unloading, and then reduction condensed water pressurized affects, avoids condensed water to be blown into by force switch board ".The more producer just increases the structure of some dash and waterproof in the evaporation side of sidewall dress air-conditioning, reduce the occurrence probability that condensed water damages the accident of electric equipment.And without exception, the producer of each sidewall installation cabinet air-conditioning is in order to evade because condensed water causes the responsibility of subscriber equipment damage, all the environment for use of oppose side wall installation cabinet air-conditioning has been made clear and definite restriction.But, be no matter that laminated structure is unloaded in restriction service condition or increase, sidewall installation cabinet air-conditioning exists all the time toward the potential safety hazard of blowing water in rack, and great device damage and stopping production accident still happen occasionally.Brand-new thorough solution of market demand.
Summary of the invention
The invention discloses the anti-sidewall installation cabinet air-conditioning that blows water of a kind of upper air-out, it comprises housing 6, evaporation side and condensation side, and evaporation side and condensation side are isolated mutually;
Wherein, evaporation side comprises evaporimeter 5, capillary/throttling arrangement 4, water accumulating disc 7, evaporation side blower fan/fan 16, cold air air outlet 21 and hot-air air inlet 23;
Condensation side comprises compressor 1, device for drying and filtering 3, condenser 2, condensation side blower fan/fan 17, high temperature air air outlet 22 and air at room temperature air inlet 24;
Wherein compressor 1 connects condenser 2 and evaporimeter 5, and device for drying and filtering 3 connects respectively condenser 2 and capillary/throttling arrangement 4, and capillary/throttling arrangement 4 connects respectively device for drying and filtering 3 and evaporimeter 5;
Wherein cold air air outlet 21 is on the top of evaporation side, and hot-air air inlet 23 is in the bottom of evaporation side, and air flows through the surface of evaporimeter 5 from the bottom up;
Wherein high temperature air air outlet 22 is on the top of condensation side, and air at room temperature air inlet 24 is in the bottom of condensation side;
Wherein evaporation side blower fan/fan 16 can be for aerofoil fan, centrifugal blower (being furnished with the wind-guiding dividing plate) or with the centrifugal blower of spiral case;
Wherein water accumulating disc 7 is in the bottom of evaporation side, for catching the condensed water of drippage;
Wherein 5 one-tenth, condenser 2 and evaporimeter fall the Eight characters, and like this, the windward side of condenser 2 and evaporimeter 5, all in the outside, is beneficial to regular clean maintenance.
The anti-sidewall installation cabinet air-conditioning that blows water of a kind of upper air-out of the present invention, its principle is: the top of the evaporation side of this sidewall installation cabinet air-conditioning heat absorption disposes the cold air air outlet, bottom disposes the hot-air air inlet, and like this, when condensed water drips from evaporator surface, process is the hot-air air inlet.Therefore because the wind of hot-air air inlet is ecto-entad, blow, the condensed water of drippage not only can not fly to the air-conditioning outside, can be blown into the air-conditioning the inside on the contrary and fall in the water accumulating disc below evaporimeter.Because condensing drip can naturally fall under Action of Gravity Field, can not fly up with the mobile cold air that makes progress, therefore, just certainly do not have condensing drip the cold air of producing by boasting from the cold air air outlet on top.
Therefore, a kind of upper air-out of the present invention anti-sidewall installation cabinet air-conditioning that blows water thoroughly removed that sidewall installation cabinet air-conditioning just exists all the time to the major safety risks of blowing water in rack.
