Effect.The projection of the low spot in 2 and two drainage face 21 of sealing element straight down is fallen in the heat exchanging part 11 of gap both sides, in this way, working as
Water droplet is slid downwards from drainage face 21 to will drip along vertical direction after minimum point, due to drainage face 21 minimum point it is perpendicular
It delivers directly shadow to be located on heat exchanger 1, therefore water droplet also can be vertically dropped on heat exchanger 1, and then drainage channel is entered by heat exchanger 1
(drip tray for being such as placed in 1 bottom of heat exchanger) occurs " blowing water phenomenon " so as to which water droplet effectively be avoided to enter inside air duct.Sealing
The upside of part 2 is equipped with catch basin 22, and at least one end of catch basin 22 is equipped with drainage interface 221, in this way, the outer surface of sealing element 2
The condensation water of generation can be collected in catch basin 22, and is passed through drainage interface 221 and drained into the structure of 1 both sides of heat exchanger (as propped up
Fagging 3 or motor cover), and then into drainage channel, without dropping to inside air duct.
Technical solutions of the utility model pass through in the splicing seams of two heat exchanging part 11 being disposed adjacent positioned at 1 top of heat exchanger
Sealing element 2 is provided at gap, two opposite drainage faces 21 are formed on the bottom of the sealing element 2, the low spot in two drainage faces 21 vertically to
Under projection fall splicing gap both sides heat exchanging part 11 on, and the upside of the sealing element 2 be equipped with catch basin 22, catch basin 22
At least one end be equipped with drainage interface 221.Have so as to condensation water caused by the medial surface and lateral surface by the sealing element 2
Effect is drained to the drainage channel discharge of air conditioner indoor unit, so as to largely avoid the generation of air-conditioning " blowing water phenomenon ".This
Outside, by the way that sealing element 2 is arranged to above structure, insulating layer just is set without the medial surface in sealing element 2, so as to effective
Simplify the structure of sealing element 2, reduce production cost, and coming off for insulating layer is avoided from root.The utility model heat exchanger 1
Sealing structure it is simple, and can effectively avoid the generation of air-conditioning " blowing water phenomenon ".
Preferably, as shown in figure 4, being equipped with drainage interface 221 in the both sides of the length direction of catch basin 22, wherein a row
Water interface 221 is connected in the motor cover of 1 side of heat exchanger, and another drainage interface 221 is connected to the support plate 3 of 1 opposite side of heat exchanger
On, so as to which the condensation water in catch basin 22 is flow to respectively in motor cover and support plate 3, finally flow into drip tray.Pass through
Drainage interface 221 is respectively provided at the both ends of catch basin 22, sealing element 2 can be avoided to make to be equipped with drainage interface due to installation error
The problem of causing condensation water that can not discharge when 221 one end is upturned.
Further, it is more firm in order to make to install between each heat exchanging part 11, usually set in the length direction side of heat exchanger 1
There is support plate 3, in order to which the water in catch basin 22 more can be easily guided in support plate 3, the sealing element 2 is close to institute
One end of support plate 3 is stated equipped with the water guide sector 23 in the support plate 3 is extended to, the water guide sector 23 is equipped with and the catch basin
The guiding gutter 231 that 22 drainage interface 221 connects.
In the present embodiment, by setting water guide sector 23 that can connect sealing element 2 and support plate 3 well, collect
Condensation water in sink 22 can be flow to along guiding gutter 231 in support plate 3, and finally flow into drip tray.Preferably, it is described to lead
The lateral cross section of sink 231 be less than the catch basin 22 lateral cross section so that flow can have when entering diversion trench compared with
Big hydraulic pressure, so as to make water velocity faster, the discharge for condensation water of being more convenient for.
Further, Fig. 5 is please referred to, the water guide sector 23 includes bottom wall 232 and set on 232 opposite sides of bottom wall
