Description
Technical field
The utility model belongs to field of water heaters, specifically, is related to the liquid-dividing head and water heater of a kind of heat pump.
Background technology
Liquid-dividing head is a kind of for by liquid and gas-liquid two-phase fluid uniform flow assigned unit, being installed on refrigeration system
In condenser and evaporator between, realize liquid or the phase refrigerant fluid of gaseous state two after evenly distributing into more than two-way to evaporating
Device, to reach purpose that refrigerant all evaporates inside evaporator, plays particularly important effect in heat pump.
When refrigerant flows in liquid-dividing head, due to the centrifugal action at turning, refrigerant is in pipeline when reaching liquid-dividing head
Distribution it is uneven.At present, although the species of liquid-dividing head is a lot, but refrigerant in the pipeline of already skewness is homogenized again
Effect is not good, and point liquid uneven phenomenon easily occurs when refrigerant enters evaporator, the ability and efficiency of system is reduced.
Patent CN201510210512.5 provides a kind of liquid-dividing head, including：One liquid-dividing head main body, liquid-dividing head main body it is upper
End has an opening, and its lower end, which has to constitute in multiple liquid outlets, liquid-dividing head main body, an open communication and multiple liquid outlets
Divide liquid inner chamber；One is offered axially through its upper and lower end in one generally cylindrical mixed flow suspension core body, mixed flow suspension core body
On the central duct in face, mixed flow suspension core body some points of liquid grooves are arranged at intervals with along cylindrical surface peripheral；And one lid be located at point
An inlet connected with described point of liquid inner chamber is offered on liquid-dividing head gland in the opening of liquid head main body, liquid-dividing head gland.
The patent utilization mixed flow suspension core body adjusts point hydraulic coupling of each liquid outlet so that point hydraulic coupling uniform one of each liquid outlet
Cause, it is ensured that the pressure balance that each group evaporator is born, it is ensured that the heat exchange coefficient of evaporator and the effect of air conditioner refrigerating.But
It is that the structure is more complicated, cost is high, when refrigerant temperature is too low, easily freezes to produce obstruction.In view of this it is special to propose this practicality
It is new.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art more simple there is provided a kind of structure

The direction Stepwize Shrink that the diameter of the through hole flows along liquid.
Through hole is set to the structure along the direction Stepwize Shrink of flow of fluid, liquid is equally existed extruding effect in through hole
Really, make gas and liquid mixture mixing more uniform.
The deflection plate convexes to form cambered surface to side, and the through hole is uniformly distributed along the cambered surface.
By the way that deflection plate is arranged into arcwall face, increase its surface area, and then increase the quantity of through hole, make liquid homogenizing effect
Fruit is more preferably.
The deflection plate at least two is simultaneously arranged at intervals along liquid flow direction, the through hole on two adjacent deflection plates
It is staggered.
By setting multiple flow mixing devices, realize and repeatedly disperse, and through hole is staggered, liquid homogenizing is more filled
Point.
The filler for being used for improving mixed effect is provided between two adjacent deflection plates.
By setting filler, make the space between two deflection plates that also there is the function of homogenizing gas and liquid mixture, enter one
Step improves homo-effect of the liquid-dividing head to gas and liquid mixture.
The flow mixing device is arranged on inlet, and the flow mixing device is detachably connected with the inlet.
The connected mode being detachably connected, makes the installation of flow mixing device, uses and changes more convenient, reduce cost.
A kind of water heater with above-mentioned liquid-dividing head.
After adopting the above technical scheme, the utility model has the advantages that compared with prior art：Due to mixed flow
Device has a plurality of flow channel for liquids, and the liquid (refrigerant) of gas-liquid skewness is by during flow channel for liquids, due to liquid flow
Road reduces with respect to transfer pipeline bore, under the double action for extruding and turning on, and is well mixed liquid；Because flow channel for liquids is equal
Even distribution, improves the dispersion effect of liquid.
