Wherein, the distance between two adjacent described through holes equates.
Wherein, described heat exchanger tube is set to three row's eight row.
Wherein, the arranged direction of described heat exchanger and the wind direction of described blower fan vertical setting mutually.
Wherein, the horizontal center line of described air inlet, the horizontal center line of the horizontal center line of described air outlet and described heat exchanger be located along the same line.
Wherein, described motor is brshless DC motor.
The beneficial effects of the utility model:
The blower fan heat exchanger tube unit of a kind of improvement of the present utility model, its water inlet for the heat exchanger tube of heat exchange is near one end of air outlet, delivery port is in the one end near air inlet, like this, current in heat exchanger tube and wind direction form contrary cross-current, when hydrophily flows with air heat exchange in the heat exchanger tube of heat exchange, its heat transfer type is countercurrent flow, effectively improve heat exchange efficiency, and then the heat exchange amount of raising unit, thereby realized energy-saving and cost-reducing object, simultaneously, distance between heat exchanger and air inlet is arranged to be greater than the distance between heat exchanger and air outlet, can make like this wind-engaging of heat exchanger more even, heat exchange property is good, the side of water-collecting tray is arranged to incline structure, catchment more convenient with quick, be conducive to the stable running of blower fan heat exchanger tube unit.

The specific embodiment
With the following Examples the utility model is further described.
The blower fan heat exchanger tube unit of a kind of improvement of the present utility model, as shown in Figure 1 and Figure 2, comprises motor 1, blower fan 2, air inlet 3, air outlet 4, side plate 5, is arranged on the water-collecting tray 6 of side plate 5 belows and is arranged on the heat exchanger 8 on side plate 5.
Heat exchanger 8 comprises support plate 10 and is arranged on the heat exchanger tube 9 on support plate; on support plate 10, be provided with for the through hole of heat exchanger tube 9 is installed, preferably, the distance between two adjacent described through holes equates; guarantee the compactness rational in infrastructure of heat exchanger 8, be convenient to project installation and maintenance.
