Abstract
The utility model discloses an adopt brazed plate heat exchanger of dicyclo type distributor, including left slab, right slab, form refrigerant entry round hole after left slab and right slab are synthetic, between left slab and the right slab and correspond refrigerant entry round hole department be provided with in the ring sum outer loop, on inner ring, outer loop and refrigerant entry round hole three's the centre of a circle is in same axis, outer loop free accommodation inner ring, it has interior osculum to open on the inner ring, it has outer osculum to open on the outer loop. The utility model discloses a plate heat exchanger can increase the pressure drop of refrigerant at heat exchanger inlet for the gaseous state refrigerant reduces at the velocity of flow of entrance, and it is more even to let gaseous state refrigerant and liquid refrigerant mix, thereby can let the flow distribution homogeneity of refrigerant between every slab of heat exchanger obtain improving, make the heat transfer ability of heat exchanger under the evaporation operating mode improve 10% 20%.
Description
Technical field
This utility model is related to a kind of brazing plate type heat exchanger.
Background technology
Brazing plate type heat exchanger is the evaporator part that commonly uses in heat pump air conditioner, and its compact conformation, heat exchange efficiency height are applied
Widely.When brazing plate type heat exchanger is used as vaporizer, a side liquid is chilled water, and a side liquid typically freezes
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 two-phase state, generally between 0.1 to 0.5, generally more than 0.9, i.e., refrigerant gas are occupied cavitation efficiency its mass dryness fraction
Most number space, and be present strong thermodynamics unbalance response in gas and liquid, have larger 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
Runner of the plate type heat exchanger near entrance sleeve, and liquid refrigerant then be subject to gaseous refrigerant retardance inflow heat exchanger away from
In the runner of entrance sleeve, the flow that this has 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 of heat exchanger exit cold-producing medium uneven, and total heat exchange amount reduction even results in local ice
Stifled, heat exchanger is damaged, is caused chilled water to penetrate into refrigerant side, is caused scrapping for whole refrigeration system.
Utility model content
The purpose of this utility model is being evaporated under operating mode to solve brazing plate type heat exchanger, there is provided a kind of using bicyclic
The brazing plate type heat exchanger of type allotter, when entrance cold-producing medium is two-phase state, can cause cold-producing medium every in plate-type heat-exchange
Assignment of traffic in individual runner is uniform.
This utility model solves the concrete scheme of its technical problem：
A kind of brazing plate type heat exchanger of employing double ring type allotter, 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 internal ring and
Outer shroud, 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, opens on internal ring
There is interior osculum, on outer shroud, be provided with outer osculum.
Described interior osculum and outer osculum are all provided with multiple.
Described inner ring and outer rings pass through impact style molding on left plate piece or right panel piece.
Plate type heat exchanger of the present utility model can increase pressure drop of the cold-producing medium in heat exchanger entrance so that gaseous refrigerant
Flow velocity in porch reduces, and makes gaseous refrigerant and liquid refrigerant mixing more uniform, such that it is able to allow cold-producing medium changing
Assignment of traffic uniformity between every plate of hot device is improved so that exchange capability of heat of the heat exchanger under evaporation operating mode is carried
High 10%-20%.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
It is described in further detail to of the present utility model below in conjunction with the accompanying drawings, but protection domain of the present utility model
It is not limited to the embodiment.
Such as Fig. 1, a kind of brazing plate type heat exchanger of employing double ring type allotter, including left plate piece 1, right panel piece 2, left plate piece
1 is ripple angle plate upwards, and right panel piece 2 is the downward plate of ripple angle, after two plates weld together, defines
The runner of cold-producing medium circulation, and forms refrigerant inlet circular hole 3, between left plate piece 1 and right panel piece 2 and corresponding refrigerant inlet circle
Be provided with internal ring 4 and outer shroud 5 at hole 3, internal ring 4,3 three of outer shroud 5 and refrigerant inlet circular hole circle centre position on the same axis,
4 diameter of internal ring is less, and 5 diameter of outer shroud is bigger than internal ring 4, internal ring 4 can be completely encased by the inside, be provided with interior osculum 6 on internal ring 4,
Outer osculum 7 is provided with outer shroud 5.
Cold-producing medium is entered 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 constituted by ring 4 and outer shroud 5, then pass through from the outer osculum 7 of outer shroud 5 again, the stream entered 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 two phase refrigerant is entered in two annulus, and then uniform mixing, after outer osculum 7 on outer shroud 5 are passed through, further saves
Stream, so as to realize cold-producing medium more uniform assignment of traffic between heat exchanger each plate, improves the overall heat exchange of heat exchanger
Amount.
The perforate direction of the outer osculum 7 on interior osculum 6 and outer shroud 5 on internal ring 4 can be any, can be according to actual distribution
Effect is adjusted；The more than one that osculum 6 and outer osculum 7 can be opened in simultaneously, can open many of N.Except putting 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 by adding
The mode of ring.
