Abstract
The invention discloses a kind of brazing plate type heat exchanger using double ring type allotter, including left plate sheet, right panel sheet, refrigerant inlet circular hole is formed after left plate sheet and the synthesis of right panel sheet, it is provided with internal ring and outer shroud between left plate sheet and right panel sheet and at corresponding refrigerant inlet circular hole, the circle centre position of internal ring, outer shroud and refrigerant inlet circular hole three is on the same axis, outer shroud encases internal ring, and internal ring has interior osculum, and outer shroud has outer osculum.The plate type heat exchanger of the present invention can increase the cold-producing medium pressure drop at heat exchanger entrance, the gaseous refrigerant flow velocity in porch is reduced, make gaseous refrigerant and liquid refrigerant mixing more uniform, such that it is able to allow cold-producing medium assignment of traffic uniformity between every plate of heat exchanger be improved so that heat exchanger exchange capability of heat under evaporation operating mode improves 10% 20%.
Description
Technical field
The present invention relates to a kind of brazing plate type heat exchanger.
Background technology
Brazing plate type heat exchanger is evaporator part conventional in heat pump air conditioner, its compact conformation, and heat exchange efficiency is high, application
Widely.When brazing plate type heat exchanger uses as vaporizer, a side liquid is chilled water, and a side liquid is typically refrigeration
Agent, two kinds of fluids are separated by heat exchanger plate, carry out fluid interchange.Under evaporation operating mode, when cold-producing medium enters plate type heat exchanger
Mostly being biphase state, its mass dryness fraction is generally between 0.1 to 0.5, and cavitation efficiency is generally more than 0.9, i.e. refrigerant gas occupies
Most of spaces, and there is strong thermodynamics unbalance response in gas and liquid, has bigger 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 type heat exchanger near the runner of entrance sleeve, liquid refrigerant then by gaseous refrigerant retardance inflow heat exchanger away from
In the runner of entrance sleeve, this flow having resulted in cold-producing medium between each plate of heat exchanger is different, the heat exchange in each runner
Amount is also different, and serious meeting causes the degree of superheat inequality of heat exchanger exit cold-producing medium, and total heat exchange amount reduces, and even results in local ice
Stifled, damage heat exchanger, cause chilled water to penetrate into refrigerant side, cause scrapping of whole refrigeration system.
Summary of the invention
The invention aims to solve brazing plate type heat exchanger under evaporation operating mode, it is provided that a kind of employing double ring type is divided
The brazing plate type heat exchanger of orchestration, when entrance cold-producing medium is biphase state, so that cold-producing medium is at each stream of plate-type heat-exchange
Assignment of traffic in road is uniform.
The present invention solves the concrete scheme of its technical problem:
A kind of brazing plate type heat exchanger using double ring type allotter, including left plate sheet, right panel sheet, left plate sheet and the synthesis of right panel sheet
Rear formation refrigerant inlet circular hole, is provided with internal ring with outer between left plate sheet and right panel sheet and at corresponding refrigerant inlet circular hole
Ring, on the same axis, outer shroud encases internal ring to the circle centre position of internal ring, outer shroud and refrigerant inlet circular hole three, and internal ring has
Interior osculum, outer shroud has outer osculum.
Described interior osculum and outer osculum all have multiple.
Described internal ring and outer shroud are by impact style molding on left plate sheet or right panel sheet.
The plate type heat exchanger of the present invention can increase the cold-producing medium pressure drop at heat exchanger entrance so that gaseous refrigerant is entering
Flow velocity at Kou reduces, and makes gaseous refrigerant and liquid refrigerant mixing more uniform, such that it is able to allow cold-producing medium at heat exchanger
Every plate between assignment of traffic uniformity be improved so that heat exchanger evaporation operating mode under exchange capability of heat improve
10%-20%。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail, but protection scope of the present invention is not limited to
Described embodiment.
Such as Fig. 1, a kind of brazing plate type heat exchanger using double ring type allotter, including left plate sheet 1, right panel sheet 2, left plate sheet
1 is ripple angle plate upwards, and right panel sheet 2 is the plate that ripple angle is downward, after two plates weld together, defines
The runner of cold-producing medium circulation, and forms refrigerant inlet circular hole 3, between left plate sheet 1 and right panel sheet 2 and corresponding refrigerant inlet circle
Be provided with internal ring 4 and outer shroud 5 at hole 3, the circle centre position of internal ring 4, outer shroud 5 and refrigerant inlet circular hole 3 three on the same axis,
Internal ring 4 diameter is less, and outer shroud 5 diameter is bigger than internal ring 4, internal ring 4 can be completely encased by the inside, internal ring 4 has interior osculum 6,
Outer osculum 7 is had on outer shroud 5.
Cold-producing medium enters from the refrigerant inlet circular hole 3 of plate, then by the interior osculum 6 of internal ring 4, then into interior
In the space that ring 4 and outer shroud 5 are formed, pass from the outer osculum 7 of outer shroud 5 the most again, enter into the stream between two plates
In road.Interior osculum 6 on internal ring 4 serves a part of throttling action to two phase refrigerant so that gaseous refrigerant flows decrease,
Then during two phase refrigerant enters into two annulus, the most uniformly mix, after by the outer osculum 7 on outer shroud 5, save further
Stream, thus realize cold-producing medium more uniform assignment of traffic between each plate of heat exchanger, improve the heat exchange that heat exchanger is overall
Amount.
The perforate direction of the interior osculum 6 on internal ring 4 and the outer osculum 7 on outer shroud 5 can be any, can distribute according to reality
Effect is adjusted；The more than one that in simultaneously, osculum 6 and outer osculum 7 can be opened, can open many of N.Except putting in runner
Enter the mode of inner and outer ring, it is also possible to by the method for punching press, inner and outer rings pressed out, i.e. form out rather than by adding
The mode of ring.
