Beneficial effects of the present invention：The present invention includes the heat exchange casing that cross section is in isosceles trapezoid shape setting, is arranged at institute
State the air exhausting device of heat exchange roof box and be arranged at the inside of the heat exchange casing and set along the length direction of heat exchange casing
The bottom centrifugation air exhausting device put, bottom centrifugation air exhausting device include symmetrically being affixed the be arranged on heat exchange box bottom
One centrifugal fan and the second centrifugal fan, the air outlet of first centrifugal fan and the second centrifugal fan are set upward, described first from
The heart fan and the second centrifugal fan air inlet respectively with heat exchange casing left heat exchanger plates and right heat exchanger plates it is corresponding, and described first from
On lateral wall between the air outlet and air inlet of heart fan, and on lateral wall between the air outlet and air inlet of the second centrifugal fan
It is provided with slope.This structure design, by exchange heat casing cross section be arranged to isosceles trapezoid shape, can expand left heat exchanger plates and
The distance between right heat exchanger plates lower end, reduces the formation of vortex, passes through the setting of the first centrifugal fan and the second centrifugal fan, Neng Goujin
Convection velocity between the left heat exchanger plates of raising of one step and right heat exchanger plates lower end, and be engaged timely with the air exhausting device on top plate
Bottom vortex is discharged, plays good drainage effect.So as to effectively improve the heat exchange uniformity of heat exchanger and heat exchange efficiency.
Brief description of the drawings
Fig. 1 is a kind of axonometric drawing of the central air-conditioning heat exchanger with centrifugal fan of the present invention.
Fig. 2 is a kind of schematic diagram of the heat exchanger cross section of the central air-conditioning with centrifugal fan of the present invention.
Embodiment
1 further illustrate technical scheme to accompanying drawing 2 and by embodiment below in conjunction with the accompanying drawings.
A kind of central air-conditioning heat exchanger with centrifugal fan, including cross section are in the heat exchange casing that isosceles trapezoid shape is set
1st, it is arranged at the air exhausting device 12 of the heat exchange top plate of casing 1 and is arranged at the heat exchange casing 1 interior edge heat exchange casing 1 and grows
The bottom centrifugation air exhausting device 16 that direction is set is spent, the bottom centrifugation air exhausting device 16 includes symmetrical be affixed and is arranged at heat exchange box
The first centrifugal fan 161 and the second centrifugal fan 162 in the internal backplane of body 1, the centrifugal fan 162 of the first centrifugal fan 161 and second
Air outlet set upward, the air inlet 1611 of the centrifugal fan 162 of the first centrifugal fan 161 and second respectively with the casing that exchanges heat
1 left heat exchanger plates 13 and right heat exchanger plates 14 are corresponding, and the air outlet of the centrifugal fan 162 of first centrifugal fan 161 and second
