Abstract
The utility model discloses a distributing device of a dry evaporator, which mainly comprises a swirling flow distributing pipe, a pipe box and a curved liquid distributing plate, wherein the inner side of the swirling flow distributing pipe has a multi-head elliptical spiral structure, the inlet of the swirling flow distributing pipe is connected with the outlet of a throttling mechanism, the outlet of the swirling flow distributing pipe is connected with the inlet of the pipe box, the curved liquid distributing plate has a three-dimensional curved surface to meet the requirement for the distribution of the pipe box and a heat-exchange pipe, the curved surface is a part of a parabolic surface fitting well with the shape of the pipe box, the focus of the parabolic surface is positioned on the extended line of the axis of the swirling flow distributing pipe, a certain number of distributing holes are formed in the curved surface as required, and the curved liquid distributing plate is arranged on the pipe box. The distributing device solves the problem of the dry evaporator in the prior art that the cold energy is reduced due to non-uniform distribution of the feed liquid, resulting in low energy efficiency.
Description
Technical field
The utility model relates to a kind of central air-conditioning heat transfer technology, relates in particular to the liquid distributing device of a kind of central air-conditioning cold water (heat pump) unit with dry evaporator.
Background technology
Central air-conditioning cold water source pump is as the central air conditioner system nucleus equipment, and its efficiency has directly determined the efficiency of central air conditioner system.Improve central air-conditioning cold water (heat pump) unit efficiency, reduce building energy consumption, be the importance of energy-saving and emission-reduction always.Dry evaporator is as one of core part of cold water (heat pump) unit, and the efficiency and the refrigerating capacity of unit had conclusive effect, also is simultaneously cold water source pump the most frequently used heat transmission equipment at present.
Because the special construction of dry evaporator, and the refrigerant fluid under the duty is the gas-liquid two-phase attitude, thus in the quality of dry evaporator import department along the import distribution of radially outward successively decreasing, promptly the cold-producing medium flow velocity of import center is greater than the flow velocity of inlet ambient.And the heat exchanger tube distribution cross section of heat exchanger is greater than inlet-duct area.Therefore be far longer than heat exchange tube inner refrigerant mass flow in heat exchange tube inner refrigerant mass flow away from import over against import, and therefore cause the state of heat exchanger tube inner refrigerant to differ, finally cause the exchange capability of heat of heat exchanger to descend, the evaporating temperature of unit descends, the unit cold descends, and efficiency reduces.
Present dry evaporator import is adopted simple porous plate separatory usually or is not adopted any liquid distributing device.Such way has directly influenced the uniformity coefficient of separatory, makes the exchange capability of heat of evaporimeter descend.
The utility model content
The purpose of this utility model is to provide a kind of dry evaporator distributor, solves prior art dry evaporator feed liquor and distributes the uneven cold that causes to descend the problem that efficiency reduces.
In order to achieve the above object, the utility model adopts following technical scheme: described dry evaporator distributor is mainly by the swirling flow distributing pipe, bobbin carriage and curved surface liquid separatnig plate constitute, the ellipse spiral curve of bull is processed in swirling flow distributing pipe inboard, the import of swirling flow distributing pipe links to each other with the outlet of throttle mechanism, the outlet of swirling flow distributing pipe links to each other with the import of bobbin carriage, distribution according to bobbin carriage and heat exchanger tube, the curved surface liquid separatnig plate is made into three-dimension curved surface, curved surface is the paraboloidal part according to the shape intercepting of bobbin carriage, paraboloidal focus is positioned on the axis extended line of swirling flow distributing pipe, and make the dispensing orifice of some as required, be installed on the bobbin carriage.
Compare with prior art, the utlity model has following advantage:
When cold-producing medium enters the swirling flow distributing pipe because the characteristic of fluid, refrigerant air-liquid can carry out primary separation, because centrifugal action, the liquid that density is big can separate to the tube wall direction, the gas that density is little then concentrates on the middle part of distributing pipe, the refrigerant mixture of process primary separation leaves distributing pipe and enters bobbin carriage, and it is axial and radially two components synthetic that the refrigerant velocities of this moment can be regarded as.Because the effect of curved surface liquid separatnig plate, the axial velocity component of cold-producing medium further reduces, and under the acting in conjunction that the guiding of curved surface convection cell and the perforate on the liquid separatnig plate distribute, it is enough makes cold-producing medium reach the position of bobbin carriage away from the distributing pipe axle center for the radial velocity component of cold-producing medium, its axial component is at each position basically identical along the bobbin carriage cross section, and therefore one's duty is equipped with the effect of having played uniform distribution of putting.
Through software simulation and test, this device has improved the heat exchange property of evaporimeter.
Description of drawings
Figure 1 shows that structural representation of the present utility model.
Among the figure
1 swirling flow distributing pipe, 2 bobbin carriages, 3 curved surface liquid separatnig plates
The specific embodiment
Below in conjunction with accompanying drawing, specify the utility model.
The dry evaporator distributor that the utility model relates to is mainly by swirling flow distributing pipe 1, bobbin carriage 2 and curved surface liquid separatnig plate 3 constitute, the ellipse spiral curve of bull is processed in swirling flow distributing pipe 1 inboard, the import of swirling flow distributing pipe 1 links to each other with the outlet of throttle mechanism, the outlet of swirling flow distributing pipe 1 links to each other with the import of bobbin carriage 2, distribution according to bobbin carriage 2 and heat exchanger tube, curved surface liquid separatnig plate 3 is made into three-dimension curved surface, curved surface is the paraboloidal part according to the shape intercepting of bobbin carriage 2, paraboloidal focus is positioned on the axis extended line of swirling flow distributing pipe 1, and make the dispensing orifice of some as required, be installed on the bobbin carriage 2.
When cold-producing medium enters swirling flow distributing pipe 1 because the characteristic of fluid, refrigerant air-liquid can carry out primary separation, because centrifugal action, the liquid that density is big can separate to the tube wall direction, the gas that density is little then concentrates on the middle part of swirling flow distributing pipe 1, the refrigerant mixture of process primary separation leaves distributing pipe and enters bobbin carriage, and it is axial and radially two components synthetic that the refrigerant velocities of this moment can be regarded as.Because the effect of curved surface liquid separatnig plate 3, the axial velocity component of cold-producing medium further reduces, and under the acting in conjunction that the guiding of curved surface convection cell and the perforate on the liquid separatnig plate distribute, it is enough makes cold-producing medium reach the position of bobbin carriage away from the distributing pipe axle center for the radial velocity component of cold-producing medium, its axial component is at each position basically identical along the bobbin carriage cross section, and therefore one's duty is equipped with the effect of having played uniform distribution of putting.
More than disclosed be the specific embodiment of this patent only, but this patent is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of this patent.
