The following technical problem that the present invention solves
1, the evaporator of completely new single copper pipe structure, solves the problems, such as cost and productivity effect.
2, completely new evaporator flow path designs are corresponding to air channel volume distribution, using re-heat, increase exchange capability of heat.
3, reasonable evaporator flow path designs guarantee that uniformity using re-heat drags down evaporator superheat between branch,
When avoiding condensation operating condition, cause to generate condensation water in air duct since temperature difference is larger.
Using the indoor heat exchanger structure and flow path designs of the embodiment of the present invention, it is ensured that under the premise of product quality, subtract
The cost of low product has great advantage for product sale.
The inventive point of the invention is:
1, the fin copper tubular type fission indoor set heat exchanger of completely new single copper pipe distribution.
2, completely new evaporator flow path designs increase exchange capability of heat and guarantee good dew condensation phenomenon when freezing condensation,
Droplet is avoided to blow out or fall.
The present invention is a kind of indoor heat exchanger of split air conditioner, is the fin copper pipe heat exchanger of the single distribution of U-tube,
Composition includes fin, U-shaped copper pipe, eyesight elbow, connecting bend, current divider, temperature-sensitive canning tube.Wherein U-shaped copper pipe is distributed as single
Distribution, both U-tube copper pipe only had a row, U pipe negligible amounts.Wherein, fin is made of aluminium foil, pitch of fins 1.2cm, 1.3cm,
1.4cm, 1.5cm or 1.6cm；The caliber of U-shaped copper pipe includesOr other thickness calibers；Evaporator side plate is steel side plate,
For fixing U-shaped copper pipe.
The indoor heat exchanger of the embodiment of the present invention increases the flow path designs of cooling heat exchange ability using re-heat, to reduce refrigerant
The pressure loss flowed in heat exchanger, heat exchanger flow circuit are designed as mostly being designed specifically to Two In and Two Out, but be not limited into having more
Two In and Two Out, wherein import and outlet are managed for adjacent U, that is, inlet and outlet need to put together, and refrigerant flow process is next
Two-way is divided into two feed liquor branch pipes 22 through current divider by feed liquor house steward 21 from the low temperature liquid refrigerant of outdoor heat exchanger, is led to
It crosses two feed liquor branch pipes 22 and respectively enters and exchange heat in two groups of heat exchanger tubes 10, the gaseous coolant after heat exchange passes through two collection
Gas branch pipe 32 simultaneously summarizes through current divider to gas gathering manifold 31, then returns to outdoor heat exchanger by gas gathering manifold 31, completes indoor heat exchange
The refrigerant circulation of device.
The liquid coolant of low temperature has temperature difference by indoor heat exchanger and indoor air temperature, in the effect of this temperature difference
It is lower to exchange heat with air, so that evaporation of absorbing heat, achievees the effect that refrigeration.By heat transfer principle, refrigerant in heat exchanger with warp
The air for crossing heat exchanger carries out heat exchange, temperature difference of the power resources between refrigerant and air, and with this temperature difference Δ T at just
Than.Refrigerant is in heat exchanger interior suction thermal evaporation, and temperature increases under the action of sensible heat, forms the temperature difference, the i.e. degree of superheat between inlet and outlet,
Cause the last one U tube temperature of exit higher, corresponding Δ T becomes smaller, and exchange capability of heat weakens.Therefore heat exchanger inlet and outlet is placed on
Together, the temperature that exit U pipe is dragged down under the temperature difference between inlet and outlet U pipe, carries out re-heat exchange.Draw high the last one U pipe
The temperature difference T between air enhances exchange capability of heat.
Meanwhile the temperature difference is larger between heat exchanger U pipe, temperature field unevenly leads to air production when touching structural member surface
Raw condensed water will be dripped blowout when condensed water is built up to a certain extent by gravity.So dragging down overheat using re-heat
Degree, drags down the temperature of heat exchanger exit, advantageously ensures that uniform heat exchange temperature field, guarantee good dew condensation phenomenon.
According to another embodiment of the invention, a kind of air conditioner, including indoor heat exchanger are provided, the indoor heat exchanger
For the indoor heat exchanger of above-described embodiment.Using the air conditioner of the indoor heat exchanger of above-described embodiment, exchanged heat by setting multiple groups
Pipe 10, heat exchanger is interior in single layer setting indoors for multiple groups heat exchanger tube 10；Wherein, the inlet and outlet of every group of heat exchanger tube 10 is adjacent sets
It sets, to reduce the quantity of heat exchanger tube 10, production cost is effectively reduced, while can guarantee the heat exchange efficiency of indoor heat exchanger
And it is effectively improved condensation situation.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
