Abstract
The curved heat exhanger mainly includes heat exchanging tubes and heat exhanging fins, the windward side and lee side of the curved heat exchanger are made into the form of curved surface, and the circular arc of windward side and circular arc of lee side of the heat-exchanging fin are identical in arc centre, and coincided with axle centre of through-flow wind wheel of indoor machine of air-conditioner so as to ensure that the distances from all the place positions of circular arc to through-flow wind wheel are identical. The described heat-exchanging tubes are divided into two rows of straight tubes, between tube and tube they are connected by means of pipe connector. Said invented heat exchanger can improve air intake condition and air intake direction.
Description
Technical field:
The present invention relates to a kind of heat exchanger, particularly a kind ofly can improve the indoor apparatus of air conditioner flow field, reduce air-conditioning noise and increase the curved heat exchanger of air quantity, belong to refrigeration technology field.
Background technology:
Heat exchanger is a requisite part in the domestic air conditioner.Particularly in indoor set, the structure of heat exchanger can not only regulate with indoor set in the heat exchange amount of air, and also very important to the air quantity and the aerodynamic noise of control indoor set.At present, most heat exchanger research mainly is to concentrate on its heat exchange function, for example, cracks augmentation of heat transfer etc. on heat exchanger fin, and from increasing air quantity and reducing the noise aspect and consider that the structural design of heat exchanger is also fewer.Along with the consumer to the improving constantly of air-conditioning noise index request, how to reduce noise from air conditioner and become the main target of air-conditioner parts design gradually.Heat exchanger as the air conditioner room unit important component part has a lot of influences to the aerodynamic noise in the control air-conditioner.Widely used heat exchanger all exists the defective that noise is big, air quantity is little in the indoor apparatus of air conditioner at present.This mainly is because now the heat exchanger diverse location that uses is different to the distance value of the interior tubular wine wheel of air-conditioner.When tubular wine wheel rotated, air-flow passed the heat exchanger fin gap and is inhaled into.The direction of air-flow before flowing to tubular wine wheel mainly is subjected to the constraint of heat exchanger structure, causes the flow inlet angle of wind wheel import to change greatly, forms certain inlet air flow winding speed, influences the performance of blower fan.Because tubular wine wheel is charge air flow speed difference everywhere, make the charge air flow of indoor set zones of different have certain air pressure difference, in this case, vortex in the wind wheel strengthens, make wind wheel produce fluctuation, increase noise, and the increasing of whirlpool makes also the exit reflux to increase, thereby reduced air quantity.Therefore be necessary to design a kind of heat exchanger that can improve the indoor apparatus of air conditioner flow field, reach the effect that reduces noise from air conditioner and increase its outlet air quantity.
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, propose a kind of air conditioner room unit curved heat exchanger of new structure.The windward side and the lee face of this heat exchanger are arc-shaped surface, and it mainly comprises heat exchanger tube and heat exchange fin.Heat exchanger tube is double circular straighttube, is linked to each other by pipe joint between the tube and tube.The windward side circular arc of heat exchange fin is consistent with the arc core of lee face circular arc, and and the axis coinciding of air conditioner room unit tubular wine wheel, the position is consistent to the distance of tubular wine wheel everywhere to guarantee circular arc.Radially be uniform-distribution with circular hole of the same size on the fin, heat exchanger tube penetrates wherein.The heat exchanger fin width of this kind heat exchanger is consistent with the various heat exchanger fin width that use at present with thickness, and two row's heat exchanger tubes radially evenly distribute on heat exchanger fin.
Because arc heat exchanger diverse location is consistent to the distance of tubular wine wheel, so just improve the tubular wine wheel inlet air conditions everywhere and the airintake direction of import department's each point air-flow, reduced and formed unnecessary flow separation when flowing through wind wheel, improve the internal flowing state of wind wheel, thereby reduce the vortex radius of air-flow in the wind wheel, reduce pneumatic eddy current crack.The curved heat exchanger front face area is big in addition, and wind wheel can be from a plurality of direction air intakes, thereby have increased the indoor apparatus of air conditioner air quantity, and the indoor set inner space also effectively utilized, and can make the miniaturization more of indoor set contour structure size.By to the band indoor set flow field of curved heat exchanger and the numerical simulation of sound field, show that it can play really and increase air quantity and reduce anti noise.
Description of drawings:
Fig. 1 is an arc heat exchanger structure schematic diagram
Fig. 2 is the arc heat exchange fin
Among the figure, 1 is heat exchange fin, 2 heat exchanger tubes, 3 windward side circular arcs, 4 lee face circular arcs, 5 circular holes.
The specific embodiment:
Below in conjunction with accompanying drawing concrete enforcement of the present invention is further described.
As shown in Figure 1 and Figure 2, the windward side of curved heat exchanger and lee face are arc-shaped surface.Curved heat exchanger mainly comprises two parts: heat exchange fin 1 and heat exchanger tube 2.Heat exchanger tube 2 is double circular straighttube, is linked to each other by pipe joint between the tube and tube.The windward side circular arc 3 of heat exchange fin 1 is consistent with the arc core of lee face circular arc 4, and and the axis coinciding of air conditioner room unit tubular wine wheel, the position is consistent to the distance of tubular wine wheel everywhere to guarantee circular arc.Arc chord angle θ decides according to the inlet angle size of cross flow fan in the air-conditioner.Inlet angle is big more, and θ is also big more, and as far as possible with the inlet angle equal and opposite in direction.Radially be uniform-distribution with circular hole 5 of the same size on the heat exchange fin 1, heat exchanger tube 2 penetrates wherein.The width of the heat exchange fin 1 of this kind heat exchanger is consistent with the various heat exchanger fins that use at present with thickness, and two row's heat exchanger tubes 2 radially evenly distribute on heat exchange fin 1.Compound mode between each parts of curved heat exchanger is consistent with common heat exchangers.Such structure can be improved the tubular wine wheel inlet air conditions everywhere and the airintake direction of import department's each point air-flow, reduce and form unnecessary flow separation when flowing through wind wheel, improve the internal flowing state of wind wheel, thereby reduce the vortex radius of air-flow in the wind wheel, reduce pneumatic eddy current crack.The curved heat exchanger front face area is big in addition, can be from a plurality of direction air intakes, thus increased the indoor apparatus of air conditioner air quantity, and the indoor set inner space also effectively utilized, and can make the miniaturization more of indoor set contour structure size.By to the band indoor set flow field of curved heat exchanger and the numerical simulation of sound field, show that it can play really and increase air quantity and reduce anti noise.
