Grade part was made between composition, some heat exchange plates 2 and was stacked by seal gasket 3 body communicating pipe 9, in adjacent heat exchanger plates
Cryogen B and cooling water space A is formed in piece 2.The groove profile header 4 has the mounting groove for installing the heat exchange plate 2.
The width of the heat exchange plate 2 installs the easiest, the heat exchange plate than the small about 4mm of plane width in groove profile header 4
2 are through in groove profile header 4 vertically.Corner apertures is provided with location on the heat exchange plate 2, can be used for connecting adjacent system
Cryogen space B or with cooling water space A.The seal gasket 3 is pasted onto on heat exchange plate 2, its act as by refrigerant with
Cooling water separates and plays sealed effect.The groove profile header 4 can abreast arrange several from top to bottom, preferably 2,
Or the multiple of 2, the effect of the groove profile header 4 is to allow refrigerant to have enough spaces to carry out gas-liquid separation.The heat exchange
Plate 2 is that a monoblock is passed through in several groove profile headers 4, due to not being by heat exchange plate 2 one after cold-producing medium stream slot-in type header 4
Straight flow down, but in advanced slot-in type header 4, the then refrigerant tubing by being set sideways in the groove profile header 4
Flow away, therefore refrigerant flow path is divided into some flows.The cryogen B inserts groove profile by air communicating pipe 7 and joined
Case 4, the refrigerant of gasification is imported in the groove profile header 4.The heat exchange plate 2 is passed vertically through among groove profile header 4, adjacent
The close closed assembly of heat exchange plate 2 form thin heat transfer fluid channels, the passage of refrigerant and cooling water is spaced apart.Due to
Heat exchanger has gas-liquid separating function, since second procedure, and the coolant channel formed by heat exchange plate 2 will be divided into gas system
Coolant channel and liquid refrigerant passage.The side of the air communicating pipe 7 is connected with groove profile header 4, opposite side and lower one stream
The corner apertures connection of the heat exchange plate 2 of journey, forms the gas refrigerant import of downstream heat exchange plate 2.Air communicating pipe 7 is inserted
Groove profile header 4, lower plane of the position away from groove profile header 4 of import has certain height, and distance about 10mm can prevent liquid system
The inflow of cryogen.The groove profile header 4 of each flow is connected to a fluid connection pipe 9, and the one end of fluid connection pipe 9 is connected to groove profile
Header 4, the other end is connected to the corner apertures of the heat exchange plate 2 of downstream.As shown in Fig. 2 fluid connection pipe 9 is connected to groove profile connection
The entry position of the side of case 4 is consistent with level.The fluid connection pipe 9 can be provided with septulum with holes in ad-hoc location
Plate, as shown in figure 3, the apertured partition is the circular bulkheads for having several small sircle holes on a surface, the diameter of circular bulkheads
Identical with the internal diameter of fluid connection pipe 9, aperture on circular bulkheads is diameter 1mm small through hole, and circular bulkheads are act as Lou
Liquid choke, that is, condense liquid energy and flowed away by aperture, and form liquid film and hinder gas refrigerant to pass through aperture.The apertured partition
It can be made up of three circular bulkheads being stacked, the adjacent direct distance of circular bulkheads is 1-3cm.
As shown in figs. 4-7, because there is gas refrigerant passage the fluid passage of the formation of heat exchange plate 2, liquid refrigerant leads to
Road and cooling-water duct, it is therefore desirable to which the seal gasket 3 on heat exchange plate is rationally set.Three flow heat exchangers are listed herein
Seal gasket form.Shown in Fig. 4 is the form of cooling-water duct, and shown in Fig. 5 is that same plate is all gas in three flows
The form of cryogen passage, shown in Fig. 6 is that same plate is gas refrigerant in the first and second flows, and the 3rd flow is
The form of liquid refrigerant passage.Because cooling-water duct is that, without separating into some flows, cooling water flows directed along heat exchange plate 2
It is at the end, the part in the insertion groove profile of heat exchange plate 2 header 4 is also required to set seal gasket 3.Coolant channel is divided into some
Flow, refrigerant is not to flow to the end, therefore the insertion groove profile of heat exchange plate 2 of coolant channel along heat exchange plate 2
Part in header 4 is to be not provided with seal gasket 3, can so be made in cold-producing medium stream slot-in type header 4.Due to heat exchange plate 2
Between form a series of coolant channels to be divided into gas refrigerant passage and liquid refrigerant in the second procedure of heat exchanger logical
Road, thus have part heat exchange plate 2 second or the 3rd flow begin with liquid refrigerant passage, its seal gasket 3 is set

Groove profile header about 4 two side planes have perforate.And the coolant channel correspondence position formed between two pieces of heat exchange plates 2 only has groove
Plane perforate on type header 4, lower plane not perforate.
The operation principle and workflow of the present invention is as follows：
As shown in figure 8, gaseous refrigerant C enters by heat exchanger plates from the overhead refrigerant import 1 of first pass heat exchange plate 2
The assignment channel of piece 2, seal gasket 3 and corner apertures formation, each heat exchange plate 2 is assigned to by refrigerant is parallel in assignment channel
In refrigerant flow path, refrigerant is flowed from top to bottom in the runner in heat exchange plate 2, and refrigerant is joined by groove profile afterwards
The rectangular opening of the upper surface of case 4 is flowed among groove profile header 4.Because the gas and liquid of refrigerant have density contrast, work as refrigerant
Flowed into from the internal channel of heat exchange plate 2 behind this larger space of groove profile header 4, gas refrigerant and liquid refrigerant can occur point
From.Because liquid is affected by gravity than larger, general liquid can drop to the bottom of groove profile header 4, and gas is up.System
Cryogen flows during being flowed in groove profile header 4 toward air communicating pipe and fluid connection pipe along horizontal direction, and
Heat exchange plate 2 passes vertically through groove profile header 4, therefore when baffling can occur after cold-producing medium stream slot-in type header 4, two-phase is freezed
Agent will have certain baffling separating effect, so as to improve gas-liquid separation effect.Air communicating pipe 7 is from the bottom surface of groove profile header 4
Insertion, entrance location has a certain distance with the lower surface of groove profile header 4, therefore is deposited on the liquid refrigerating of the bottom surface of groove profile header 4
Agent can not be flowed away by the pipe, and only gas refrigerant can enter air communicating pipe 7, then flow into the heat exchange plate of downstream
2 continue condensing heat-exchange.The downstream that liquid refrigerant then flows into heat exchange plate from the fluid connection pipe 9 of bottom continues to exchange heat
It is cold.Meanwhile, the porous circular bulkheads set in fluid connection pipe 9 also play the effect of leakage choke, prevent gas from entering
Fluid connection pipe 9.Although gas refrigerant and liquid all enter the downstream of heat exchange plate 2, by reasonable simultaneously
Seal washer 3 on heat exchange plate 2 is set, and passage and the liquid refrigerant E passages of gas refrigerant are to separate.Gas and liquid
Cryogen exchanges heat in corresponding heat exchanger channels respectively.Finally, whole refrigerants all leaves heat exchange by refrigerant outlet 6
Device.Due to the gas refrigerant passage different from liquid refrigerant inflow, so the structure serves the effect of gas-liquid separation.Together
When, during condensing heat-exchange, gas refrigerant is constantly reduced, and condensate liquid is on the increase, so the gas refrigeration of downstream
Agent passage is less than the gas passage of a upper flow, and liquid refrigerant passage is more than the liquid refrigerant passage of a upper flow.
Cooling water D enters heat exchanger from cooling water inlet 5, is then redistributed to by heat exchange plate 2 and seal gasket 3 and angle
The assignment channel that hole is formed, cooling water is uniformly flowed into assignment channel in the aquaporin of each heat exchange plate 2, and water is in plate
Between flow direction be from the bottom up, be with the direction of refrigerant it is opposite, formed countercurrent flow.The flowing of cooling water does not have
It is divided into some flows, but flows to plate top always along heat exchange plate 2 from bottom and enter collection channel, from plate top
Cooling water outlet 8 leaves heat exchanger.
