It is the reason of air-conditioning can be discharged.The water in water tank is extracted out incessantly with water circulating pump, and is equably sprayed by water distribution system
Leaching is on evaporative filtration layer, and hot outdoor air enters evaporative cooling medium, in the evaporative cooling medium CELdek (bee of special substance
Nest shape filter layer, makes cooling effect more preferable, the high-tech patented product of Sweden) in sufficiently carry out heat with water and exchange, because of water
Evaporation endothermic and refrigerant, the clean air that cools down are pressurizeed by low-noise fan to be sent into indoor, and indoor hot-air is made to be discharged to room
Outside, to achieve the purpose that room temperature lowering.
In air-conditioning equipment, there is dispenser capillary insertion copper pipe and insertion depth will be inserted into metal plate or less and carry out group
Dress, and much smaller than copper pipe of most of capillary diameter, are unfavorable for welding, and generate the sound because of vibration after installing.

First thermally conductive adhesive layer, graphite linings and the second thermally conductive adhesive layer；The first thermally conductive adhesive layer and the second thermally conductive adhesive layer are adopted
Use epoxide-resin glue.
Preferably, the capillary includes tube body and radiating fin, and the outer wall of the tube body is arranged in the radiating fin
On, the radiating fin is uniformly distributed along the length direction of the tube body, and the tube body is to be detachably connected with radiating fin.
Preferably, internal diameter matches after internal diameter with the copper pipe flaring of the coupling tube.
Preferably, the internal diameter with copper pipe of the connecting tube are not flared internal diameter and match.
Preferably, the capillary, coupling tube, connecting tube are TP2M.
Preferably, a kind of connection method for the structure that capillary is connect with copper pipe, comprising the following steps:
A, the coupling tube that first welding of institute's tubule matches with internal diameter after copper pipe flaring, capillary need to stretch out outside coupling tube；
B, capillary weld and copper pipe the connecting tube that internal diameter matches then is not flared again；
C, finally by the coupling tube insertion copper pipe welding on capillary.
Compared with prior art, the beneficial effects of the present invention are:
(1) connection structure of the invention is suitable for all heat exchangers, facilitates welding, can prevent capillary weld copper pipe is welding fluid
It flows into, reduces capillary and copper pipe shakes the sound for generation of colliding.
