Description
Technical field
The present invention relates to a kind of filed of air conditioning more particularly to heat exchanger tube, full-liquid type heat exchanger and heat pump air conditioner units.
Background technology
The widely used heat exchanger of heat pump air conditioner unit is full-liquid type heat exchanger at present.Using the heat pump of full-liquid type heat exchanger
Air-conditioner set is low pressure saturated liquid refrigerant under cooling condition, outside heat exchanger tube, and refrigerant evaporation absorbs the heat of the water in cooling tube
Amount provides low temperature cold source for cooling；Under the operating mode that heats, full-liquid type heat exchanger is converted to condenser, is that high pressure is cold outside heat exchanger tube
The water in heat exchanger tube is heated in matchmaker's steam, refrigerant steam condensation heat release, provides high temperature heat source for heating.This kind of heat pump air conditioner unit
Middle the used heat exchanger tube of full-liquid type heat exchanger needs while meeting evaporation and heat-exchange performance and condensing heat-exchange performance.
Although evaporation and condensation are all phase-change heat-exchanges, its principle is different.Evaporation needs the more nucleus of boiling to strengthen
Heat transfer effect；And condense and larger heat exchange area is then needed so that gaseous coolant is condensed into liquid, while needing the solidifying of generation
Knot liquid is quickly drained, it is avoided to form liquid film thermal resistance in heat exchange surface, reduces heat exchange property.

Two kinds of casts of evaporation tube and full-liquid type condenser pipe.
It is shown according to experimental data, condenser pipe is done using existing full-liquid type evaporation tube in use, its condensation performance can compare
The condenser pipe of existing single condensation reduces by 30% or more；Equally, do evaporation tube using existing full-liquid type condenser pipe in use,
Its volatility can be than 35% or more the evaporation tube performance degradation of existing single evaporation.Therefore, do not increasing number of heat exchange tubes
Under the premise of, the simple full-liquid type heat exchanger for using traditional evaporation tube or condenser pipe, it is difficult to meet heat pump air conditioner unit in work
Needs when condition adjusts to freezing and heating.Certainly in same full-liquid type heat exchanger, equally attempted using evaporation tube and
The piping mode of condenser pipe mixing arrangement and upper layer condenser pipe lower layer evaporation tube, to the full-liquid type heat exchanger respectively as steaming
When sending out device and condenser, it can meet the needs of two kinds of operating modes of refrigeration and heating, but effect is still not satisfactory.
Volatility had not only been required to full-liquid type heat exchanger based on heat pump air conditioner unit but also has required the functional requirement of condensation performance,
A bottleneck for being developed into unit development for the dual-purpose heat exchanger tube of evaporative condenser in full-liquid type heat exchanger.

Fracture 10 is discharged, while the liquid refrigerants in inner cavity 7 is supplemented also by gap 5 or the second fracture 10.
The heat exchanger tube of the present embodiment uses under heating operating mode as condenser pipe.1 outside high pressure gaseous coolant of tube body is main
It is condensed in exocoel 6, the wing top 4 of fin and the first groove 9 thereon are to pass through extrusion forming so that at the top of wing
4 and 9 both sides of the first groove it is more sharp, be conducive to puncture refrigerant bubble so that gaseous coolant rapid condensation be liquid, exocoel
First groove 9 of 6 side wall surfaces and inclined horizontal fin portion 3 increase the surface area of exocoel 6, particularly to the condensation heat transfer of gaseous coolant
It is important.Since horizontal fin portion 3 is inclined or is bent, the liquid refrigerants for condensing generation thereon is comprehensive in surface tension and its gravity
Cooperation flows downward under, and drains into inner cavity 7 by gap 5 in time and further cooled down, and is connected to since inner cavity 7 is circumferential,
A certain amount of liquid refrigerants is finally run up to by heat exchanger tube bottom discharge heat exchange pipe surface.
The embodiment of the present invention forms the exocoel 6 of the inner cavity 7 and suitable condensation heat transfer that are suitble to evaporation and heat-exchange using horizontal fin portion 3,
And according to the corresponding principle of work and power to respectively partly strengthening so that the heat exchanger tube volatility and condensation performance are carried
Height, meets the requirement of the cooling condition and heating operating mode of heat pump air conditioner unit, and makes the efficiency of heat pump air conditioner unit into one
Step improves.
As shown in Figure 3 and Figure 4, the embodiment and Fig. 1 and embodiment shown in Fig. 2 main difference is that, 4 at the top of wing
Upper formation spine 12 and third groove 13.Spine 12 and third groove 13 are between two adjacent first grooves 9.And it is multiple
Spine 12 and multiple third grooves 13 are uniformly distributed along the channel that fin is formed trend respectively.The setting of spine 12 and third groove 13
So that heat exchanger tube as condenser pipe in use, further increasing heat exchange area, spine 12 can also puncture refrigerant bubble, make gas
State refrigerant rapid condensation is liquid, further enhances condensation effect.
The unaccounted part of the embodiment of the present invention can refer to the associated description of other embodiments.
As shown in Figure 5 and Figure 6, the embodiment and Fig. 1 and embodiment shown in Fig. 2 the difference is that, it is disconnected with first
Mouth 14 replaces the first groove 9.Can be by the first fracture 14 of fashion of extrusion 4 formation certain depths at the top of wing, and fracture is deep
Degree reaches the position in horizontal fin portion 3.14 and second fracture 10 of multiple first fractures is uniformly distributed along the circumferencial direction of tube body 1 respectively.
The unaccounted part of the embodiment of the present invention can refer to the associated description of other embodiments.
As shown in Figure 7, Figure 8, the embodiment and Fig. 5 and embodiment shown in fig. 6 the difference is that, 4 direction at the top of wing
On one side surface in horizontal fin portion 3, spine 12 and third groove 13 are formed by squeezing, spine 12 and third groove 13 are located at two
Between adjacent first fracture 14, and multiple spines 12 and multiple third grooves 13 are uniformly distributed along the channel that fin is formed trend.
Heat exchanger tube is as condenser pipe in use, further increase heat exchange area, and spine 12 can puncture refrigerant bubble so that gaseous state is cold
Matchmaker's rapid condensation is liquid, further enhances condensation effect.
The unaccounted part of the embodiment of the present invention can refer to the associated description of other embodiments.
From the above description, it can be seen that the embodiment of the present invention at least realizes one of following technique effect：
Heat exchanger tube can take into account volatility and condensation performance simultaneously, meet heat pump air conditioner unit to cooling condition and heating work
The requirement of properties of hot pipe is exchanged under condition；Promote the efficiency of heat pump air conditioner unit；Reduce heat-pump air-conditioner group cost；Accelerate heat pump empty
Adjust the popularization and application of unit.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the specific implementation mode of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
