Abstract
A kind of water conservancy diversion plate-type installs ventilating duct, including heat exchanger (1) and ventilating duct (2), and heat exchanger (1) is in back taper, and blower fan (3) is installed in ventilating duct (2), it is characterised in that：Ventilating duct (2) includes horizontal annular rib (21), annular rib (21) be distributed in heat exchanger (1) on along upper, the guide shell (22) of taper is formed on the inner ring of annular rib (21), the upper end of guide shell (22) forms vertical air duct (23), and blower fan (3) is distributed in air duct (23).It is simple in construction, easily manufactured, and the structure of ventilating duct is optimized, and so as to eliminate dead space, realizes airflow smooth, effectively increases the heat exchange efficiency of heat exchanger.
Description
Technical field：
The technical field of blower fan is the utility model is related to, ventilating duct is installed more specifically to a kind of water conservancy diversion plate-type.
Background technology：
Typically be installed on blower fan on existing heat exchanger, to accelerate heat exchange efficiency, its blower fan install with ventilating duct, wind-guiding
Cylinder is connected with the body of heat exchanger；There is a kind of heat exchanger of flat board plate-type air duct structure at present, as shown in figure 1, this is flat
Board-like ventilating duct 2 ' is made up of ring baffle 21 ' and straight air duct 22 ', but existing defects, and such as the arrow in Fig. 1, it represents air-flow
Direction, air-flow by heat exchanger 1 from ventilating duct outflow during, its fraction be flat ventilating duct 2 ' on annular
Baffle plate 21 ' is stopped, that is, is formed the dead space a of dash area in such as Fig. 1, then influenceed heat exchange efficiency.
Utility model content：
The purpose of this utility model and provides a kind of water conservancy diversion plate-type installation wind-guiding aiming at the deficiency of prior art
Cylinder, it optimizes the structure of ventilating duct, effectively increases the heat exchange efficiency of heat exchanger.
A kind of water conservancy diversion plate-type installs ventilating duct, including heat exchanger and ventilating duct, and heat exchanger is in back taper, is pacified in ventilating duct
Provided with blower fan, ventilating duct includes horizontal annular rib, annular rib be distributed in heat exchanger on along upper, the inner ring of annular rib
On form the guide shell of taper, the upper end of guide shell forms vertical air duct, and blower fan is distributed in air duct.
Preferably, described heat exchanger uses gilled radiator, is not more than on heat exchanger along the side edge length of inner ring and leads
The side edge length of annular rib inner ring on air duct.
Preferably, the coning angle of the heat exchanger is 20~45 °, and the channelization angle α of guide shell is not more than 60 ° on ventilating duct.
The beneficial effects of the utility model are：
It is simple in construction, easily manufactured, and the structure of ventilating duct is optimized, and so as to eliminate dead space, realizes
Airflow smooth, effectively increase the heat exchange efficiency of heat exchanger.
Brief description of the drawings：
Fig. 1 is the structural representation of flat board plate-type ventilating duct；

Fig. 3 is the structural representation of the utility model ventilating duct；
In figure：1st, heat exchanger；2nd, ventilating duct；21st, annular rib；22nd, guide shell；23rd, air duct；3rd, blower fan；2 ', it is flat
Ventilating duct；21 ', ring baffle；22 ', straight air duct；A, dead space.
Embodiment：
Embodiment：As shown in Fig. 2,3, a kind of water conservancy diversion plate-type installs ventilating duct, including heat exchanger 1 and ventilating duct 2, heat exchange
Device 1 is in back taper, and blower fan 3 is installed in ventilating duct 2, and ventilating duct 2 includes horizontal annular rib 21, and annular rib 21 is distributed in
Along upper on heat exchanger 1, the guide shell 22 of taper is formed on the inner ring of annular rib 21, the upper end of guide shell 22 forms perpendicular
Straight air duct 23, blower fan 3 are distributed in air duct 23.
Described heat exchanger 1 uses gilled radiator, is not more than ventilating duct 2 along the side edge length of inner ring on heat exchanger 1
The side edge length of the upper inner ring of annular rib 21.
The coning angle of the heat exchanger 1 is 20~45 °, and the channelization angle α of guide shell 22 is not more than 60 ° on ventilating duct 2.
Operation principle：The utility model is that water conservancy diversion plate-type installs ventilating duct, and cone is being set up (shown in Fig. 3) to ventilating duct 2
The structure of guide shell 22 of shape, from airflow smooth is realized, air-flow will not stop air-flow would not then occur by annular rib 21
Dead angle, so as to effectively increase the heat exchange efficiency of heat exchanger.
The embodiment is to illustrative the utility model, not for limitation the utility model.Any this area
Technical staff can modify without prejudice under spirit and scope of the present utility model to the embodiment, therefore this practicality
New rights protection scope, should be as listed by claim of the present utility model.
