Abstract
The invention discloses a kind of brazing plate type heat exchangers using double ring type distributor, including left plate piece, right panel piece, refrigerant inlet circular hole is formed after left plate piece and the synthesis of right panel piece, it is provided with inner ring and outer rings between left plate piece and right panel piece and at corresponding refrigerant inlet circular hole, the circle centre position of inner ring, outer shroud and refrigerant inlet circular hole three is on the same axis, outer shroud encases inner ring, and interior osculum is provided in inner ring, outer osculum is provided on outer shroud.The plate heat exchanger of the present invention can increase pressure drop of the refrigerant in heat exchanger entrance, so that flow velocity of the gaseous refrigerant in inlet reduces, gaseous refrigerant and liquid refrigerant is allowed to mix more uniform, so as to allow assignment of traffic uniformity of the refrigerant between every plate of heat exchanger to be improved so that exchange capability of heat of the heat exchanger in the case where evaporating operating mode improves 10% 20%.
Description
Technical field
The present invention relates to a kind of brazing plate type heat exchangers.
Background technology
Brazing plate type heat exchanger is common evaporator part in heat pump air conditioner, it is compact-sized, and heat exchange efficiency is high, application
Widely.For brazing plate type heat exchanger as evaporator in use, a side liquid is chilled water, a side liquid is typically to freeze
Agent, two kinds of fluids are separated by heat exchanger plate, carry out fluid interchange.In the case where evaporating operating mode, when refrigerant enters plate heat exchanger
Mostly two-phase state, mass dryness fraction is usually between 0.1 to 0.5, and usually 0.9 or more, i.e. refrigerant gas occupies cavitation efficiency
Most number space, and gas and liquid has larger there are strong thermodynamics unbalance response between gas phase and liquid phase
Velocity-slip, i.e. the flowing velocity of gaseous refrigerant is higher than liquid refrigerant, thus gaseous refrigerant can be caused to occupy
Plate heat exchanger is close to the runner of entrance sleeve, and liquid refrigerant is then separate by the retardance inflow heat exchanger of gaseous refrigerant
In the runner of entrance sleeve, this has resulted in the flow difference of refrigerant between each plate of heat exchanger, the heat exchange in each runner
Amount is also different, and the serious degree of superheat that can lead to heat exchanger exit refrigerant is uneven, and total heat exchange amount reduces, and even results in local ice
It is stifled, heat exchanger is damaged, causes chilled water to penetrate into refrigerant side, causes scrapping for entire refrigeration system.
Invention content
The purpose of the present invention is to solve brazing plate type heat exchangers in the case where evaporating operating mode, provides a kind of using double ring type point
The brazing plate type heat exchanger of orchestration can make refrigerant each be flowed in plate-type heat-exchange when entrance refrigerant is two-phase state
Assignment of traffic in road is uniform.
The concrete scheme that the present invention solves its technical problem is：
A kind of brazing plate type heat exchanger using double ring type distributor, including left plate piece, right panel piece, left plate piece and right panel piece
Refrigerant inlet circular hole is formed after synthesis, be provided between left plate piece and right panel piece and at corresponding refrigerant inlet circular hole inner ring and
Outer shroud, on the same axis, outer shroud encases inner ring to the circle centre position of inner ring, outer shroud and refrigerant inlet circular hole three, is opened in inner ring
There is interior osculum, outer osculum is provided on outer shroud.
The interior osculum and outer osculum are all provided with multiple.
The inner ring and outer rings are molded by impact style in left plate piece or right panel on piece.
The plate heat exchanger of the present invention can increase pressure drop of the refrigerant in heat exchanger entrance so that gaseous refrigerant is entering
Flow velocity at mouthful reduces, and allows gaseous refrigerant and liquid refrigerant to mix more uniform, so as to allow refrigerant in heat exchanger
Every plate between assignment of traffic uniformity be improved so that exchange capability of heat of the heat exchanger in the case where evaporating operating mode improves
10%-20%。
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
The present invention is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
The embodiment.
Such as Fig. 1, a kind of brazing plate type heat exchanger using double ring type distributor, including left plate piece 1, right panel piece 2, left plate piece
1 is the upward plate of ripple angle, and right panel piece 2 is that the downward plate of ripple angle forms after two plates weld together
The runner of refrigerant circulation, and refrigerant inlet circular hole 3 is formed, between left plate piece 1 and right panel piece 2 and corresponding refrigerant inlet is justified
Be provided with inner ring 4 and outer shroud 5 at hole 3, the circle centre position of 3 three of inner ring 4, outer shroud 5 and refrigerant inlet circular hole on the same axis,
4 diameter of inner ring is smaller, and 5 diameter of outer shroud is bigger than inner ring 4, inner ring 4 can be completely encased by the inside, interior osculum 6 is provided in inner ring 4,
Outer osculum 7 is provided on outer shroud 5.
Refrigerant enters from the refrigerant inlet circular hole 3 of plate, then by the interior osculum 6 of inner ring 4, then into interior
In the space that ring 4 and outer shroud 5 are formed, is then passed through from the outer osculum 7 of outer shroud 5 again, enter the stream between two plates
In road.Interior osculum 6 in inner ring 4 plays a part of throttling action to two phase refrigerant so that gaseous refrigerant flows decrease,
Then two phase refrigerant enters in two annulus, and then uniformly mixing further saves after by outer osculum 7 on outer shroud 5
Stream, to realize refrigerant more uniform assignment of traffic between each plate of heat exchanger, improves the heat exchange of heat exchanger entirety
Amount.
The opening direction of the outer osculum 7 on interior osculum 6 and outer shroud 5 in inner ring 4 can be arbitrary, can be according to practical distribution
Effect is adjusted；The more than one that osculum 6 and outer osculum 7 can be opened in simultaneously can open more of N.In addition to being put in runner
Enter the mode of inner and outer ring, inner and outer rings can also be pressed out, that is, formed out by the method for punching press, rather than pass through addition
The mode of ring.
