Description
Technical field
The present invention relates to a kind of finned heat exchanger more particularly to a kind of composite fin heat exchangers based on bionic principle.
Background technology
With the raising of quality of the life, in addition to power conservation requirement, people to the mute performance requirements of the white domestic appliances such as air-conditioning not
It is disconnected to improve.An important indicator of the indoor fan coil pipe noise as comfort of air conditioner, is paid close attention to by more and more users.It is existing
There is the finned heat exchanger of air-conditioning products normally only to consider to go heat exchange energy-efficient performance requirement, its sound-deadening and noise-reducing emphasis is mainly concentrated
On motor.In fact, since fan coil is mostly concealed, fan coil motor internal generates noise and mainly passes through air-supply
Oral instructions are multicast to interior, and on the other hand, the flow noise of fresh air and finned heat exchanger is also important noise source.
On State Intellectual Property Office of the People's Republic of China website, patent 2 related to the present invention is found, it is specific to believe
Breath is as follows：
(1) title：Central air conditioning fan coil unit denoising device
Application number：CN201320726763.5
Inventor：Shi Xianhu
Abstract：Central air conditioning fan coil unit denoising device, it is related to technical field of noise treatment.It includes and fan coil
The air inlet and air outlet communicated, folding strip-type silencer is mounted at the air inlet and air outlet, and the tabs formula is eliminated the noise
Multiple " Pie " type muffler plates are provided in device.The utility model neither influences the air output of air-conditioning, and can reduce its noise.
(2) title：A kind of low noise axial fan composite bionic airfoil fan
Application number：CN201710455803.X
Inventor：It is turned into the spring；Wang Jing；Bao Yangchun；Zhang Xiumei；Yue Yongli；Ren Luquan
Abstract：A kind of low noise axial fan composite bionic airfoil fan category fluid machinery blade design and flowing control skill
Art field, composite bionic airfoil fan design proposed by the present invention aerofoil profile used are the modification aerofoil profile of 6405 aerofoil profiles of NACA, by
Multiple bionical units are formed by connecting in space, which has periodical indent leading edge, pointed tooth structure trailing edge and ridge-like structure table
Region feature, the pressure face and suction surface of blade are the space curved surface that multiple camber is constituted, the centre in section where two crestal lines
Position is a bionical unit, and the width and thickness at crestal line centre position is smaller than two Location of ridge axis of bionical unit.The present invention
The temporal-spatial evolution process of laminar boundary layer or turbulent boundary layer can be controlled effectively, have lower sensibility to Reynolds number,
Axial flow blower can be made to all have good aeroperformance and acoustical behavior under full working scope.
Existing air-conditioning products are can be seen that from above-mentioned patent, sound-deadening and noise-reducing has the following disadvantages：
(1) reduction fan noise is taken into consideration only, or sound-deadening and noise-reducing is realized by changing air port macroshape, is lacked from microcosmic
Angle considers finned heat exchanger muting schemes；
(2) noise-reducing structure design comparison is simple, and the friction noise to how to reduce air outlet fresh air and fin, which lacks, to be considered,
Whole noise reduction is limited.
(3) it is mute with it is energy saving be air-conditioning two core qualities, current heat-exchanger products to how to take into account it is mute with section
Energy quality considers insufficient.
Invention content
The object of the present invention is to provide a kind of composite fin heat exchanger based on bionic principle, it is micro- by optimization design fin
Structure is seen, while realizing that the noise reduction of heat exchanger is mute and enhanced heat exchange.
For achieving the above object, the technical scheme is that：A kind of composite fin heat exchange based on bionic principle
Device, including several plate-shaped fins disposed in parallel, the fin are bionical aerofoil profile fin, and bionical aerofoil profile fin includes being arranged in parallel
Advection portion, advection portion be tabular；Advection portion one end extends to outside plate, and flexes outward to form pars contractilis along plate thickness direction,
Pars contractilis end is inwardly collapsed along plate thickness direction, forms half elliptic portion windward；
Several apertures are through on the bionical aerofoil profile fin, aperture is arranged along plate thickness direction, adjacent bionical aerofoil profile fin
On aperture it is interlaced.
Preferably, the pars contractilis is isosceles trapezoid to one kind as this programme.
Preferably, the bionical aerofoil profile fin side wall is equipped with rectangular mesh to one kind as this programme, and the aperture setting exists
Rectangular mesh node location, and the aperture is located at the center that adjacent bionical aerofoil profile fin corresponds to rectangular mesh.
Preferably, the bionical aerofoil profile fin is made one kind as this programme of aluminium, copper metal material or plastic processing.
Preferably, the ratio between the semiaxis of minister windward and semi-minor axis are 4 to one kind as this programme:1.
Preferably, advection portion spacing is 2-5mm to one kind as this programme.
Preferably, the small aperture is 0.2-0.5mm to one kind as this programme.
The beneficial effects of the invention are as follows：
(1) the bionical aerofoil profile fin thickness of the present invention is gradually reduced along airflow direction, and gas channel is broadening, and air-flow rubs with fin
It wipes power to reduce, can effectively inhibit the noise of 1000HZ or more；In addition, by the way that staggeredly small is arranged on bionical aerofoil profile fin
Hole makes one noise reduction cavity of each keyhole formation, can slacken 1000HZ noises below, noise reduction wide frequency range, comfort
It is good.
(2) using the present invention when, air-flow is flowed to from bionical aerofoil profile fin side by aperture another under the influence of pressure difference
