Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
The present embodiment provides a kind of defrosters, as shown in figures 1-4, including defrosting duct interface 1, access chamber 2, first
Diversion cavity 3, the second diversion cavity 4 and spout 5, wherein defrosting duct interface 1 with defrosting duct for connecting, and the one of access chamber 2
End and defrosting duct interface 1 connect, one end connection of the other end and the first diversion cavity 3, the other end and second of the first diversion cavity 3
Diversion cavity 4 connects, the other end and spout 5 connection of the second diversion cavity 4.The cross section of spout 5 is rectangular, and end face on it
The length direction of upper edge spout 5 is equipped with multiple nozzles 51, and nozzle 51 is linear in double leaf, and the quantity of nozzle 51 is even number, each other
It contacts with each other and two adjacent nozzles 51 is oppositely arranged, multiple independent flow-guiding channels 41 are equipped in the second diversion cavity 4；It leads
The quantity of circulation road 41 and the quantity of nozzle 51 are equal, and connect one to one；Multiple flow-guiding channels 41 are along the second diversion cavity 4
Length direction be arranged at equal intervals, flow-guiding channel 41 is tapered, and face nozzle 51, specifically, the one of the flow-guiding channel 41
End opening is small, as outlet end；Another end opening is big, as arrival end, is gradually tapered up from arrival end to outlet end, is open big
One end is connected to the first diversion cavity 3, and the small one end that is open is connect with nozzle 51, and the depth of flow-guiding channel 41 is 20mm~30mm,
Specifically, can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm or 30mm.
The present embodiment can flow through the thermal current acceleration of flow-guiding channel 41 by the flow-guiding channel 41 of setting taper, from
And thermal current can be projected with higher flow velocity from nozzle 51, forming jet stream can when it is acted in windscreen surface
To accelerate the thawing of frost, and vortex is not allowed to be also easy to produce in the exit of flow-guiding channel 41, reduction air flow resistance can be preferable
Air-flow flowing is guided, jet stream is made directly to be ejected from nozzle 51；By the way that the linear nozzle 51 of double leaf and anti-each other is arranged
To setting, the thermal current of adjacent two nozzles 51 injection is interfered in the diffusion into the surface of windshield, can be formed stagnant
Stop, and expand heat transfer region, make the thermal current there are high flow velocities in the regional extent of bigger, increases velocity heated gas and frost
Active area, fully complete thermal current and frost heat exchange, can realize defrosting in a relatively short period of time.
The width of the rectangular section of spout 5 is 5mm~10mm, and length is 150mm~200mm, specifically, width can be
5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm or 10mm, length can be 150mm,

The linear Shape equation of double leaf is：
(x2+y2)2=4Lx2y
Wherein：(x, y) is coordinate of the point in rectangular coordinate system on double folium, and origin is linear two leaves of the double leaf
The intersection point of valve, with the symmetrical centre of linear two flaps of double leaf for the directions y, with the orientation of two flaps for the directions x, L is
Value be equal to spout 5 width, the unit of x, y, L are mm.
The cross section of first diversion cavity 3 is rectangular, has certain angle of inclination between access chamber 2, to hot gas
Stream from access chamber 2 after entering the first diversion cavity 3, and the flow direction of gas changes, specifically, making the direction of air-flow and in the second water conservancy diversion
Airflow direction in chamber 4 is consistent, is sprayed from the second diversion cavity 4 convenient for thermal current.The depth of first diversion cavity 3 be 10mm~
20mm, it is preferred that can be 10mm, 12mm, 15mm, 17mm or 20mm.In the present embodiment, chamber 2 and the second diversion cavity 4 are accessed
In airflow direction there are certain angle, by the way that the first diversion cavity 3 is arranged, can slow down access chamber 2 and the second diversion cavity 4 it
Between differential seat angle, can to avoid air-flow directly by access chamber 2 enter the second diversion cavity 4, prevent thermal current due to angle change mistake
Greatly, cause the flow velocity of thermal current to reduce, influence thermal current injection.
The present embodiment also provides a kind of automobile, including the defroster in said program.
When defroster at runtime, recirculated water first flows through engine, and heater cores are flowed into after flowing through heater, adds
Engine is flowed back to after hot cold air again, completes a cycle.Stream passes through heater cores after cold air is sucked by wind turbine, and by warm wind
The hot water of core heats, and becomes hot-air, and thermal current then flows into defrosting duct interface 1 by defrosting duct, subsequently into connecing
Enter chamber 2, enter the first diversion cavity 3 by accessing chamber 2, the stream of gas is adjusted back into the second diversion cavity 4 through the first diversion cavity 3
Each flow-guiding channel 41 in, sprayed by linear 51 jet stream of nozzle of double leaf after the acceleration of flow-guiding channel 41, in front windshield
With after the frost layer heat exchange on glass on glass, melt the frost layer on glass.
The present embodiment nozzle 51 linear by the way that multiple double leafs are arranged, and two neighboring nozzle 51 is oppositely arranged, to
When the thermal current of two neighboring nozzle 51 is ejected into the surface of windshield, it may occur that interfere, and mutually blend, increase heat
The active area of air-flow and windshield can be such that the heat in thermal current makes full use of, and accelerate the thawing speed of frost.
