Description
Technical field
The invention belongs to plate type heat exchanger medium throttling technology, specifically relate to a kind of slit type throttle structure of plate heat exchanger medium entrance.
Background technology
Commonly used in refrigerating field is plate type heat exchanger, such as air conditioner refrigerating etc., utilizes the evaporation of medium to absorb a large amount of heats in two staggered and runners that isolate mutually, with refrigeration such as second fluid ratio such as air.Adopting this plate type heat exchanger as aspect the refrigeration system of evaporimeter, a more insoluble problem is to enter the medium of plate type heat exchanger intake channel because factors such as flow velocity, pressure are difficult to be evenly distributed to each evaporation runner between the heat transfer plate, such maldistribution can cause near the medium of medium inlet part heat transfer plate interlayer also by unnecessary overheated, and effectively do not utilize away from the medium of medium inlet part heat transfer plate interlayer, the one, refrigerating efficiency is low, and the 2nd, energy waste.Be difficult to the uniform distribution problem for what solve above-mentioned plate type heat exchanger medium, some schemes have been arranged in the prior art, such as publication number is the throttle structure that all records medium in " the equal orchestration at the plate heat exchanger medium entrance place " patent document of CN101178294 and " plate type heat exchanger that has multi-throttling device " patent document that publication number is CN1888805, can solve the medium problem that is assigned to each evaporation runner between the heat transfer plate heterogeneous of intake channel preferably.Because prior art medium throttling distribution structure design is very unreasonable, often brings following defective: or all orchestration and heat exchange plate are difficult to one-body moldedly, manufacture inconvenience, assembly technology is loaded down with trivial details, the percent defective height; Or all orchestration can be one-body molded with heat exchange plate, but repeatedly punching press of needs, complex production process, production cost height.
Summary of the invention
The present invention solves above-mentioned existing in prior technology technical problem, and a kind of slit type throttle structure of plate heat exchanger medium entrance is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of slit type throttle structure of plate heat exchanger medium entrance, described plate type heat exchanger is intervally superimposed with each other to form by some forward heat exchange plates and reverse heat exchange plate, the outside, the edge of forward heat exchange plate medium through hole is provided with the depressed area with respect to forward heat exchange plate medium through hole off-centre on the described forward heat exchange plate, the bottom at broad position, described depressed area is provided with at least one medium and leaks orifice, constitutes slow flow cavity between this depressed area and the top reverse heat exchange plate; Oppositely the outside, the edge of heat exchange plate medium through hole and reverse heat exchange plate medium through hole are concentric on the described reverse heat exchange plate is provided with protruding endless belt, the width of this projection endless belt is consistent with the width of depressed area narrower region, and adjacent depressed area bottom surface and protruding endless belt upper bottom surface be seal welding mutually; Forward heat exchange plate medium through hole slightly constitutes its edge to recessed sinking and goes up protruding endless belt on the described forward heat exchange plate, reverse heat exchange plate medium through hole slightly upwards highlights and makes its edge to constitute the lower convexity endless belt on the described reverse heat exchange plate, constitute slit between adjacent last protruding endless belt and the lower convexity endless belt, slit and slow flow cavity connect.The medium that has a certain pressure enters the slow flow cavity decompression of expanding via slit, enters medium runner via leaking orifice again, and medium enters medium runner again after the unhurried current decompression, can so that homogeneous media be assigned to each medium runner between the heat transfer plate.
As preferably, the described slit of between protruding endless belt and the lower convexity endless belt can have multiple version, can be whole piece ring-shaped continuous structure; Can also be to go up between protruding endless belt and the lower convexity endless belt intermittently seal welding and make slit be interrupted circulus; Can also be slit a narrower region setting of going up between protruding endless belt and the lower convexity endless belt towards the depressed area, and the remainder seal welding.
As preferably, the position corresponding with the medium leakage orifice of forward heat exchange plate is provided with medium runner and gangs up the hole on the described reverse heat exchange plate, medium runner gangs up the hole and medium runner connects, many design medium runners are ganged up the hole, one can be more preferably and makes medium be assigned in each medium runner, the 2nd, in case prevent that medium from leaking orifice and stopping up, medium runner is ganged up the hole and can be worked as standby hole and guarantee that medium can be assigned in each medium runner.
The medium throttle structure of plate type heat exchanger of the present invention is a body disposable punch forming on heat exchange plate, and is simple in structure, reasonable in design, and it is convenient to manufacture, and can simplify assembly technology, has improved yield rate, has reduced production cost.
