Abstract
The invention discloses an air cooler with micro-channels, and provides an air cooler which can achieve a high refrigerating effect under a small refrigerating fluid charge volume. A fan and a micro-channel evaporator are arranged in an outer shell. The micro-channel evaporator comprises a first liquid collecting pipe, a second liquid collecting pipe, a plurality of liquid inlet end flow path micro-channels and a plurality of gas return end flow path micro-channels, wherein the liquid inlet end flow path micro-channels are communicated with the first liquid collecting pipe, the gas return end flow path micro-channels are communicated with the second liquid collecting pipe, the liquid inlet end flow path micro-channels and the gas return end flow path micro-channels are respectively provided with fins, and a liquid inlet and a gas return opening are formed in the second liquid collecting pipe. The micro-channel evaporator is arranged in an air supply outlet of the fan, and a vortex air mixing device is arranged between the micro-channel evaporator and the air supply outlet of the fan. According to the air cooler, the micro-channel evaporator is used for achieving cooling of air, and therefore the amount of refrigerating fluid which flows through a pipeline is small, meanwhile, the refrigerating fluid can also be fully evaporated, the refrigerating effect is brought into full play, and the high refrigerating effect can be achieved when the refrigerating fluid charge volume is small. The structural size of the air cooler is reduced.
Description
Technical field
The present invention relates to technical field of refrigeration equipment, particularly relate to a kind of microchannel air-cooler.
Background technology
Air-cooler is a kind of evaporation type cool-down ventilation machine group that integrates cooling, ventilation etc., and air comes the air of the outer forced flow of cooling tube to reach the purpose to air cooling-down by the heat exchange evaporation comb in air-cooler.
At present, for cold-producing medium can be given full play to refrigeration, the refrigerant charge in the evaporator section pipeline of air-cooler is very few, still, because refrigerant amount is very few, causes refrigerating capacity not reach requirement, and the evaporator section overheated zone is longer.If the cold-producing medium of overcharge, cold-producing medium but can not evaporate fully in the evaporator section pipeline, can not bring into play well its refrigeration, and the waste that has produced part of refrigerant, this just needs the length that extends the evaporator section pipeline that it is fully evaporated, thereby increase the physical dimension of air-cooler, step up its investment.
Summary of the invention
The objective of the invention is for the technological deficiency existed in prior art, and provide a kind of, can realize the air-cooler that there is higher refrigeration under less refrigerant charge.
For realizing that the technical scheme that purpose of the present invention adopts is:
A kind of microchannel air-cooler, comprise micro-channel evaporator, fan, shell, and described fan and micro-channel evaporator are installed in described shell; Described micro-channel evaporator comprises the first collector tube, the second collector tube, a plurality of liquid feeding end flow processs microchannel, a plurality of air return end flow processs microchannel, described liquid feeding end flow process microchannel and air return end flow process microchannel are communicated with described the first collector tube and the second collector tube, be separately installed with fin on each described liquid feeding end flow process microchannel and air return end flow process microchannel, liquid feeding end and air return end dividing plate are installed in described the second collector tube, on described the second collector tube, are separately installed with inlet and gas returning port; The rear portion of described micro-channel evaporator is equipped with described fan, and described outer casing bottom is equipped with the chassis of catchmenting.
Micro-channel evaporator is positioned at the outlet side of fan.
The eddy current air mixing device is installed between micro-channel evaporator and fan.
Compared with prior art, the invention has the beneficial effects as follows:
1, air-cooler of the present invention adopts micro-channel evaporator to realize the cooling of air, make the refrigerant amount of the pipeline of flowing through less, cold-producing medium also can evaporate fully simultaneously, well brings into play refrigeration, when less refrigerant charge, higher refrigeration can be arranged.And, reduced the physical dimension of air-cooler.
2, air-cooler of the present invention is arranged on the evaporimeter rear portion by fan, adopt discharge formula air-supply structure, can, so that under frozen condition, utilize wind-force that the frost on micro-channel evaporator surface is blown off, make frost in the accumulation of micro-channel evaporator surface, not improve heat transfer effect.
3, air-cooler of the present invention adopts the eddy current air mixing device, makes evaporimeter section intake more even, carries out heat exchange with the pipeline of evaporator section better, has improved the refrigerating capacity of air-cooler.
