A fan and a microchannel evaporator are mounted in an outer shell. The microchannel evaporator comprises a first liquid collecting pipe, a second liquid collecting pipe, a plurality of liquid inlet end flow microchannels and a plurality of air return end flow microchannels, wherein the liquid inlet end flow microchannels and the air return end flow microchannels are communicated with the first liquid collecting pipe and the second liquid collecting pipe, all the liquid inlet end flow microchannels and the air return end flow microchannels are provided with fins, a liquid inlet and an air return port are formed in the second liquid collecting pipe, the microchannel evaporator is arranged in an air feed port of the fan, and an eddy air blending device is arranged between the microchannel evaporator and the air feed port. According to the microchannel air cooler, the microchannel evaporator is adopted to achieve cooling of air, the amount of refrigerants flowing through a pipeline is made to be small, the refrigerants can be evaporated fully, a cooling function can be well performed, and the high cooling effect can be achieved with small refrigerant charge. The structural dimension of the air cooler is reduced.

Description

Microchannel air-cooler
Technical field
The utility model relates to technical field of refrigeration equipment, particularly relates 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 object 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 evaporator section overheated zone is longer.If the cold-producing medium of overcharge, cold-producing medium but can not evaporate fully in evaporator section pipeline, can not bring into play well its refrigeration, and the waste that has produced part of refrigerant, this length that just need to extend evaporator section pipeline is fully evaporated it, thereby increase the physical dimension of air-cooler, step up its investment.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and provide a kind of, can realize the air-cooler under less refrigerant charge with higher refrigeration.
For realizing the technical scheme that the purpose of this utility model adopts, be:
A microchannel air-cooler, comprises 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, described in each, on liquid feeding end flow process microchannel and air return end flow process microchannel, be separately installed with fin, 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 provided with described fan, and described outer casing bottom is provided with the chassis of catchmenting.
Micro-channel evaporator is positioned at the outlet side of fan.
Eddy current air mixing device is installed between micro-channel evaporator and fan.
Compared with prior art, the beneficial effects of the utility model are:
1, air-cooler of the present utility model adopts micro-channel evaporator to realize the cooling of air, the refrigerant amount of pipeline of making to flow through is less, cold-producing medium also can evaporate fully simultaneously, well brings into play refrigeration, when less refrigerant charge, can have higher refrigeration.And, reduced the physical dimension of air-cooler.
2, air-cooler of the present utility model is arranged on 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 utility model adopts eddy current air mixing device, makes evaporimeter section intake more even, carries out heat exchange better with the pipeline of evaporator section, has improved the refrigerating capacity of air-cooler.
Accompanying drawing explanation
Figure 1 shows that the front view of the utility model microchannel air-cooler;
Figure 2 shows that the side view of the utility model microchannel air-cooler;
Figure 3 shows that the schematic diagram of micro-channel evaporator.
In figure: 1. inlet, 2. gas returning port, 3. the second collector tube, 4. fin, 5-1. liquid feeding end flow process microchannel, 5-2. air return end flow process microchannel, 6. fan, the chassis of 7. catchmenting, 8. liquid feeding end and air return end dividing plate; 9. micro-channel evaporator, 10. eddy current air mixing device, 11. shells; 12. first collector tubes.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of the utility model microchannel air-cooler as shown in Figure 1-Figure 3, comprises micro-channel evaporator 9, fan 6, shell 11, and described fan 6 and micro-channel evaporator 9 are installed in described shell 11.Described micro-channel evaporator 9 comprises the first collector tube 12, the second collector tube 3, a plurality of liquid feeding end flow process microchannel 5-1, a plurality of air return end flow process microchannel 5-2, described liquid feeding end flow process microchannel 5-1 and air return end flow process microchannel 5-2 are communicated with described the first collector tube 12 and the second collector tube 3, described in each, on liquid feeding end flow process microchannel 5-1 and air return end flow process microchannel 5-2, be separately installed with fin 4, in described the second collector tube 3, liquid feeding end and air return end dividing plate 8 are installed, on described the second collector tube 3, are separately installed with inlet 1 and gas returning port 2.The rear portion of described micro-channel evaporator 9 is provided with described fan 6, and described outer casing bottom is provided with the chassis 7 of catchmenting.
In order to realize uniform heat exchange, the rear portion of described fan 6 is provided with eddy current air mixing device 10, can adopt vortex flow fan.
Cold-producing medium enters the second collector tube of micro-channel evaporator from inlet, by the second collector tube, enter liquid feeding end flow process microchannel, in the microchannel of liquid feeding end flow process, carry out part evaporation, enter the first collector tube, by the first collector tube, enter in the microchannel of air return end flow process and continue evaporation, finally from muffler, flow out.In the process that cold-producing medium circulates in evaporation tubes, blower fan constantly turns round, and wind direction as shown in Figure 2 can reduce evaporator section pipe surface frosting degree, is convenient to defrosting; The use of eddy current shell, can make outside air equably with the heat exchange of heat exchanger, integral body has improved the refrigerating capacity of microchannel air-cooler.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
