Abstract
The invention discloses an air conditioner coil pipe which can reduce noises by means of a streamline section, relates to the technical field of air conditioners and solves the problems that as for existing air conditioning systems, coil pipes increase fluid wind resistance, heat exchange efficiency of the air conditioners is reduced, and mute comforts of the air conditioners are affected due to generated vortex wind noises. The cross section of the air conditioner coil pipe is in a drop shape, and the axis of the cross section of the air conditioner coil pipe is parallel to airflow fluid moving direction of a condenser or an evaporator of an air conditioner. According to the air conditioner coil pipe which can reduce noises by means of the streamline section, wind resistance of airflow fluids which pass through a condenser coil pipe and an evaporator coil pipe in the air conditioner is reduced, unit heat exchange area is increased, the heat conversion efficiency is increased, tail vortex generated by the airflow fluids which pass through a circular coil pipe or an elliptical coil pipe can be eliminated, wind noises of the air conditioner can be reduced, and the comforts of the air conditioner can be improved.
Description
Technical field
The present invention relates to air-conditioning technical field, particularly relate to a kind of utilize streamline section to carry out noise abatement air conditioner condensation coil pipe and evaporation coil.
Background technology
The device that air-conditioning is temperature to room (or enclosure space, region) interior air, humidity, the parameter such as cleanliness factor and air velocity regulate, to meet the requirement of human comfort or technical process.
Air-conditioning carries out two-way heat exchange by evaporation coil and condenser coil, the comfort air cooled or heated directly is sent into indoor simultaneously.From fluid-mechanics point of view analysis, coil pipe is arranged perpendicular to air motion direction thick and fast, and air-flow then does transverse movement relative to coil pipe and from walking around around it, for air-flow, condenser coil and evaporation coil are actually a windage.Condenser coil and evaporation coil need to strengthen heat exchanger effectiveness on the one hand; On the other hand, as a windage, need again the fluid behaviour optimizing windage, otherwise condenser coil and evaporation coil can reduce the heat exchanger effectiveness of air-conditioning.
Refer to Fig. 1, in the air-conditioning system of prior art, how rounded coil pipe cross section is or oval.When air-flow fluid is by circular or elliptic cross-section and after crossing full-size cross section, fluid wake flow exists eddy current A.And the eddy current A of fluid can increase the windage of heat exchange air-flow to a certain extent, on the other hand, the eddy current A of afterbody has cut off the heat exchange area of a coil pipe part, reduces the heat exchanger effectiveness of air-conditioning; Simultaneously, eddy current A is also a noise source of air-conditioning system, because directly enter the interior space by the air-flow fluid of evaporation coil, the wind of coil pipe is made an uproar and directly can be had influence on the quiet comfortableness of air-conditioning, although and the fluid vortex of condenser coil does not affect indoor quiet, have larger environmental noise.
Summary of the invention
For in existing air-conditioning system, coil pipe adds fluid windage, reduce the heat exchanger effectiveness of air-conditioning, and its eddy current wind produced is made an uproar, the problem of the quiet comfortableness affecting air-conditioning, the object of this invention is to provide a kind of air-conditioning coil pipe utilizing streamline section to carry out noise abatement.
The technical solution adopted for the present invention to solve the technical problems is: the cross section of described air-conditioning coil pipe is water-drop-shaped, and the described axis of air-conditioning coil pipe cross section is parallel with the air-flow fluid direction of motion in the condenser of air-conditioning or evaporimeter.
Preferably, the cross section of described air-conditioning coil pipe has end and a small end greatly, and the large end of described air-conditioning coil pipe is near the air inlet of described condenser or evaporimeter, and the small end of described air-conditioning coil pipe is near the air outlet of described condenser or evaporimeter.
The outer surface smoother transition of described air-conditioning coil pipe.
Effect of the present invention is: based on flow dynamics analysis, the present invention adopts cross section to be the air-conditioning coil pipe of water-drop-shaped, when air conditioning air flow fluid by cross section be fairshaped coil pipe carry out heat exchange time, the windage of air-flow fluid reduces, and improves the thermal conversion efficiency of air-conditioning, on the other hand, be compared to circle and oval coil pipe, droplet-shaped (streamlined) coil pipe is under same cold medium flux, and the surface heat exchange area of coil pipe itself is comparatively large, also further increasing the thermal conversion efficiency of air-conditioning; Meanwhile, air-flow fluid is by behind the cross section of water-drop-shaped coil pipe small end, and its tail wind eliminates the eddy current that air-flow fluid produces, and the wind reducing air-conditioning is made an uproar, and improves the comfortableness of air-conditioning.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described;
Fig. 1 is the schematic diagram that in existing air-conditioning system, fluid flows through circle bronze pan tube in condenser or evaporimeter;
Fig. 2 is the schematic diagram that fluid flows through air-conditioning coil pipe in condenser of the present invention or evaporimeter.
Detailed description of the invention
Below by cited embodiment by reference to the accompanying drawings, technology contents of the present invention and feature will be described in detail.For sake of convenience, hereinafter described " on ", the position relationship that indicates of D score, "left", "right", " transverse direction ", " longitudinal direction " etc. is based on position relationship shown in the drawings, mainly in order to describe the present invention and embodiment better, be not intended to limit the particular orientation that indicated device, element or part must have, or carry out constructing and operating with particular orientation, therefore can not become the restriction of technical solution of the present invention.
Composition graphs 2 illustrates the air-conditioning coil pipe utilizing streamline section noise abatement of the present invention, in described air-conditioning condenser or evaporimeter, the cross section of air-conditioning coil pipe 100 is water-drop-shaped (streamlined), and the axis direction of air-conditioning coil pipe 100 cross section is parallel with the air-flow fluid direction of motion in air-conditioning condenser or evaporimeter.Air-conditioning coil pipe 100 cross section has greatly end 101 and a small end 102, and wherein the large end 101 of air-conditioning coil pipe 100 is near the air inlet of condenser or evaporimeter, and the small end 102 of air-conditioning coil pipe 100 is near the air outlet of condenser or evaporimeter.The transition of air-conditioning coil pipe 100 outer surface smoother.
Adopt the air-conditioning coil pipe of airflow design, when air conditioning air flow fluid laterally across cross section be fairshaped coil pipe carry out heat exchange time, the windage of air-flow fluid reduces, and improves the thermal conversion efficiency of air-conditioning.Meanwhile, air-flow fluid is by behind air-conditioning coil pipe 100 small end 102 cross section, and its tail wind eliminates the eddy current that air-flow fluid produces, and then the wind reducing air-conditioning is made an uproar, and improves the comfortableness of air-conditioning.
