The heat exchange spray nozzle provided by the invention is applied to small sized narrow and long cavity energy exchange field domains and small sized narrow and long cavity liquid gas exchange field domains, such as heat exchange in water cooling top operation, can improve the exchange activity ratio, and overcome the defect of low exchange activity ratio brought by a pressure stationary region easily formed during the operation of a single-port spray nozzle.
Description
Technical field:
The invention belongs to spraying technique field, be specifically related to a kind of heat exchange nozzle.
Background technology:
Exchange field domain and small-sized elongated cavity body fluid gas exchange field domain for small-sized long and narrow cavity energy, the device now for exchange interaction is with single mouth nozzle over 100 years, the one in the fluid tip not adopting current various document to announce.Existing single mouth nozzle within it spraying operation time easily form pressure stagnant zone and Liang Ge region, flowable state region at small-sized long and narrow cavity field domain, and fluidised form is disorderly, media flow resistance is large, make exchange interaction undesirable, regardless of function, used medium, injection spreading form how the fluid tip announced of existing various document, it is characterized by injection direction forward or enclose side, spray spreading field domain and fill, its goal task completion rate is higher.But exchange field domain and small-sized elongated cavity body fluid gas exchange field domain at small-sized long and narrow cavity energy, the fluid tip that existing various document has been announced is more just undertaken to do what is apparently beyond one's ability, its advantage just becomes shortcoming, fluid tip disclosed in JP 2001-37431, its top jet mouth and its axis are an angle, to a certain degree making the media flow in pressure stagnant zone, because its top jet mouth is multiple and the expansion of area coverage ambassador pressure stagnant zone, it is also poorer than single mouth nozzle that experimental result shows its exchange interaction.Nozzle arrangements disclosed in JP 2007-120344, behind its top, position surrounding is provided with multiple jet and the angle of its top axis is less than 90 °, make the easily mineralization pressure stagnant zone and comparatively large before its top of the medium fluid power after injection, it is also poorer than fluid tip disclosed in JP 2001-37431 that experimental result shows its exchange interaction.
Summary of the invention:
The object of the present invention is to provide a kind of heat exchange nozzle, to overcome the deficiencies in the prior art.
Heat exchange nozzle provided by the present invention comprises tip nozzles 1, eddy flow Zhu Wen district nozzle 2, releases accelerating region nozzle 3 and nozzle body 4; Described nozzle body 4 is the combination of frustum of a cone body and pipe body, and the large end portion of the frustum of a cone body of described nozzle body 4 is connected with the pipe body of described nozzle body 4; Described tip nozzles 1 is positioned at described nozzle body 4 foremost, the injection direction vector front of described tip nozzles 1 and with the axis coaxle of described nozzle body 4; Described eddy flow Zhu Wen district nozzle 2 is provided with several and is distributed on the nearly small end part of the frustum of a cone body of described nozzle body 4, the injection direction vector spreading of described eddy flow Zhu Wen district nozzle 2 is the region of 90 ° to 110 ° in the injection direction vector with described tip nozzles 1, and described eddy flow Zhu Wen district nozzle 2 sprays direction vector spray the projection in direction vector plane perpendicular to described tip nozzles 1 parallel with the tangent line of the cross section Internal periphery perpendicular to described nozzle body 4 axis; Described release accelerating region nozzle 3 is provided with several and after being positioned at described eddy flow Zhu Wen district nozzle 2, described release accelerating region nozzle 3 is distributed on the near large end portion of the frustum of a cone body of described nozzle body 4, the injection direction vector spreading of described release accelerating region nozzle 3 is the angular regions of 120 ° to 150 ° in the injection direction vector with described tip nozzles 1, and described release accelerating region nozzle 3 sprays direction vector spray the projection in direction vector plane perpendicular to described assault nozzle 1 parallel with the tangent line of the cross section Internal periphery perpendicular to described nozzle body 4 axis.
Heat exchange nozzle of the present invention is when exchanging spraying operation, and tip nozzles, for breaking the dynamic balance state of small-sized long and narrow cavity internal pressure stagnant zone, reduces or eliminates pressure stagnant zone; Eddy flow Zhu Wen district nozzle is used for arranging as contorted nonturbulent flow state by losing dynamic balance state medium, to reduce the fluid resistance of medium, increases the exchange of the small-sized elongated cavity body region in nozzle place, eddy flow Zhu Wen district, increase after Medium Exchange to back pressure; Release accelerating region nozzle for increase after Medium Exchange to back pressure, accelerate the speed of discharging small-sized long and narrow cavity after Medium Exchange, keep the contorted nonturbulent flow state after Medium Exchange, increase the exchange of the small-sized elongated cavity body region in described release accelerating region nozzle place.Through the operation successively of tip nozzles, eddy flow Zhu Wen district nozzle, release accelerating region nozzle, improve the exchange rate and exchange velocity that exchange medium in field domain.
