The following technical problem that the present invention solves
1, the vaporizer of brand-new single copper pipe structure, solves cost and productivity effect problem.
2, brand-new vaporizer flow path designs is corresponding to air channel volume distribution, utilizes re-heat, increases exchange capability of heat.
3, rational vaporizer flow path designs, it is ensured that uniformity between branch, utilizes re-heat, drags down evaporator superheat,
When avoiding condensation operating mode, in causing air channel owing to temperature contrast is relatively big, produce condensation water.
Use indoor heat exchanger structure and the flow path designs of the embodiment of the present invention, it is ensured that on the premise of product quality, subtract
The cost of low production, has great advantage for production marketing.
The inventive point of the invention is:
The fin copper tubular type split indoor set heat exchanger of 1, brand-new single copper pipe distribution.
2, brand-new vaporizer flow path designs, increases exchange capability of heat, when freezing condensation, it is ensured that good dew condensation phenomenon,
Avoid globule blowout or fall.
The present invention is the indoor heat exchanger of a kind of split air conditioner, and it is the fin copper pipe heat exchanger of the single distribution of U-tube, its
Composition includes fin, U-shaped copper pipe, eyesight elbow, connecting bend, diverter, 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 up of aluminium foil, a pitch of fins is 1.2cm, 1.3cm,
1.4cm, 1.5cm or 1.6cm；The caliber of U-shaped copper pipe includesOr other thickness calibers；Vaporizer side plate is steel side plate, its
For fixing U-shaped copper pipe.
The indoor heat exchanger of the embodiment of the present invention utilizes re-heat to increase the flow path designs of cooling heat exchange ability, for reducing coolant
The pressure loss of flowing in heat exchanger, more heat exchanger flow circuit is designed as entering and has more, and is designed specifically to two and enters scene 2, but is not limited to
Two enter scene 2, and wherein, import is adjacent U pipe with outlet, namely imports and exports needs and puts together, and coolant flow process is next
It is divided into two-way by feed liquor house steward 21 through diverter from the low temperature liquid coolant of outdoor heat exchanger and enters two feed liquor arms 22, logical
Crossing in two feed liquor arms 22 respectively enter two groups of heat exchanger tubes 10 and carry out heat exchange, the gaseous coolant after heat exchange passes through two collection
Gas branch pipe 32 also collects to gas gathering manifold 31 through diverter, then returned 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, in the effect of this temperature difference through indoor heat exchanger and indoor air temperature
Lower carry out heat exchange with air, thus evaporation of absorbing heat, reach the effect freezed.By heat transfer principle, coolant in heat exchanger with warp
The air crossing heat exchanger carries out heat exchange, power resources temperature difference between coolant and air, and just becomes with this temperature difference Δ T
Ratio.Coolant absorbs heat evaporation in heat exchanger, and under the effect of sensible heat, temperature raises, and forms the temperature difference, the i.e. degree of superheat between import and export,
Causing last U pipe temperature of exit higher, corresponding Δ T diminishes, and exchange capability of heat weakens.Therefore heat exchanger inlet and outlet is placed on
Together, under the temperature difference imported and exported between U pipe, drag down the temperature of exit U pipe, carry out re-heat exchange.Draw high last U pipe
And temperature difference T between air, strengthens exchange capability of heat.
Meanwhile, between heat exchanger U pipe, the temperature difference is relatively big, and temperature field is uneven causes air to produce when touching structural member surface
Raw condensation water, is accumulated to a certain degree when condensing water, will be dripped blowout by action of gravity.So it is overheated to utilize re-heat to drag down
Degree, drags down the temperature of heat exchanger exit, advantageously ensures that uniform heat exchange temperature field, it is ensured that good dew condensation phenomenon.
