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.
Utility model content

The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of structure that capillary is connect with copper pipe,
Including capillary, coupling tube and connecting tube, the coupling tube and capillary weld, the connecting tube and capillary weld.
Preferably, the connecting tube includes outer tube and inner tube, and being bonded between the outer tube and inner tube by adhesive layer is one
Body, said inner tube inner wall are coated with erosion resistant coating, and resistance to compression layer is arranged in the outer tube outer wall；
The adhesive layer includes the first PET film and the second PET film, is successively set between first PET film and the second PET film
It is equipped with the 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
It is all made of 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.
Compared with prior art, the utility model has the beneficial effects that
(1) connection structure of the utility model is suitable for all heat exchangers, facilitates welding, can prevent capillary weld copper
Pipe is that welding fluid flows into, and reduces capillary and copper pipe shakes the sound for generation of colliding.
(2) connecting tube and capillary that the utility model uses all have good heat dissipation performance.
