Description
Technical field：
The invention belongs to spraying technique field, and in particular to a kind of heat exchange nozzle.
Background technology：
Field domain is exchanged for small-sized long and narrow cavity energy and small-sized elongated cavity body fluid gas exchanges field domain, is currently used for exchanging and is made
Device is one kind in the fluid tip that the current various documents of use have been announced with single mouth nozzle over 100 years.It is existing
There is single mouth nozzle easily to form pressure stagnant zone and liquid flow zone in small-sized long and narrow cavity field domain in its interior spraying operation
Domain Liang Ge regions, and fluidised form is disorderly, media flow resistance is big, makes exchange interaction undesirable, the stream that existing various documents have been announced
Body nozzle regardless of function, used medium, injection spreading form how, it is characterized in that injection direction forward or encloses side, injection
Spreading field domain fills, and its goal task completion rate is higher.But exchange field domain and small-sized long and narrow cavity in small-sized long and narrow cavity energy
Liquid gas exchanges field domain, and the fluid tip that existing various documents have been announced more just is undertaken to do what is apparently beyond one's ability, and its advantage is just changed into shortcoming, such as JP
Fluid tip disclosed in 2001-37431, its top jet mouth and its axis are at an angle, make pressure quiescent centre to a certain degree
Media flow in domain, because its top jet mouth is the expansion of multiple and area coverage ambassador's pressure stagnant zone, experimental result shows
Show that its exchange interaction is also poorer than single mouth nozzle.The nozzle arrangements as disclosed in JP 2007-120344, its top after position surrounding
There is provided multiple jets and the angle of its top axis to be less than 90 °, makes the preceding shape easily at the top of it of the medium flow field muscle power after injection
Into pressure stagnant zone and larger, experimental result shows its exchange interaction than fluid tip disclosed in JP 2001-37431 also
Difference.
The content of the invention：
It is an object of the invention to provide a kind of heat exchange nozzle, with overcome the deficiencies in the prior art.
Heat exchange nozzle provided by the present invention includes tip nozzles 1, eddy flow Zhu Wen areas nozzle 2, releases accelerating region nozzle 3
And nozzle body 4；The nozzle body 4 is the combination of frustum of a cone body and pipe body, the big end of the frustum of a cone body of the nozzle body 4
Part is connected with the pipe body of the nozzle body 4；The tip nozzles 1 are located at the front end of the nozzle body 4, the top spray
Mouth 1 injection direction vector in front of and with the axis coaxle of the nozzle body 4；The eddy flow Zhu Wen areas nozzle 2 is provided with several
And the nearly small end part of the frustum of a cone body of the nozzle body 4 is distributed on, the injection direction vector of the eddy flow Zhu Wen areas nozzle 2
Spreading sprays in the region that the injection direction vector with the tip nozzles 1 is in 90 ° to 110 °, the eddy flow Zhu Wen areas nozzle 2
Direction vector is in the projection in the tip nozzles 1 injection direction vector plane and perpendicular to the axis of nozzle body 4
Section Internal periphery tangent line it is parallel；The release accelerating region nozzle 3 is provided with several and is located at the eddy flow Zhu Wen areas nozzle 2
Afterwards, the nearly big end part released accelerating region nozzle 3 and be distributed on the frustum of a cone body of the nozzle body 4, described release accelerate
The injection direction vector spreading of area's nozzle 3 is in the angular area that the injection direction vector with the tip nozzles 1 is in 120 ° to 150 °
Domain, the accelerating region nozzle 3 of releasing spray direction vector in the throwing in the assault nozzle 1 injection direction vector plane
Shadow is parallel with the tangent line of the section Internal periphery perpendicular to the axis of nozzle body 4.
For heat exchange nozzle of the present invention when exchanging spraying operation, tip nozzles are quiet for breaking small-sized long and narrow cavity internal pressure
The only dynamic balance state in region, is reduced or eliminated pressure stagnant zone；Eddy flow Zhu Wen areas nozzle is used to that dynamic balance state medium will to be lost
Arrange as contorted nonturbulent flow state, to reduce the fluid resistance of medium, small-sized elongated cavity where increase eddy flow Zhu Wen areas nozzle
The exchange of body region, increase after Medium Exchange to back pressure；Accelerating region nozzle is released to be used to increasing after Medium Exchange backward
Thrust, accelerate to discharge the speed of small-sized long and narrow cavity after Medium Exchange, keep medium exchange after contorted nonturbulent flow state, increase
The exchange of small-sized elongated cavity body region where adding the release accelerating region nozzle.By tip nozzles, eddy flow Zhu Wen areas nozzle, push away
Go out the operation successively of accelerating region nozzle, improve the exchange rate and exchange velocity for exchanging medium in field domain.
