Abstract
The utility model discloses a notch type throttle structure at a medium entrance of a plate heat exchanger. A medium through hole on a forward heat exchange plate is sunk together with an outer edge, the medium through hole on a reverse heat exchange plate is protrudent together with the outer edge, and the outer edge of the medium through hole on the adjacent forward heat exchange plate and the outer edge of the medium through hole on the reverse heat exchange plate are welded in a sealing manner. At least one notch is arranged on the outer edge of the medium through hole on the forward heat exchange plate, the bottom of the notch exceeds the outer edge of the medium through hole on the reverse heat exchange plate, and the notch and a medium flow way are communicated; or at least one notch is arranged on the outer edge on the reverse heat exchange plate, the bottom of the notch exceeds the outer edge of the medium through hole on the forward heat exchange plate, and the notch and the medium flow way are communicated. A medium enters the medium flow way through the notch, and then the medium can be evenly distributed to all the medium flow ways between the heat exchange plates. The notch type throttle structure is formed by one-shot stamping, thereby facilitating the manufacture, simplifying the assembly process and reducing the production cost.
Description
Technical field
The utility model belongs to plate type heat exchanger medium throttling technology, specifically relates to a kind of gap 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 utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of gap type throttle structure of plate heat exchanger medium entrance is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of gap 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, medium through hole is recessed heavy together with the outer on the described forward heat exchange plate, medium through hole highlights together with the outer on the described reverse heat exchange plate, the outer of medium through hole seal welding mutually on the outer of medium through hole and the reverse heat exchange plate on the adjacent forward heat exchange plate.If the diameter of the outer of medium through hole is greater than the diameter of the outer of medium through hole on the reverse heat exchange plate on the forward heat exchange plate, so just on the outer of the medium through hole of forward heat exchange plate, at least one breach is set, and the bottom of breach exceeds the outer of medium through hole on the reverse heat exchange plate, and described breach and medium runner connect; If the diameter of the outer of medium through hole is less than the diameter of the outer of medium through hole on the reverse heat exchange plate on the forward heat exchange plate, so just on the outer of medium through hole on the reverse heat exchange plate, at least one breach is set, and the bottom of breach exceeds the outer of medium through hole on the forward heat exchange plate, and described breach and medium runner connect.The medium that has certain pressure enters medium runner via breach, can realize the throttling medium by the number and the size thereof of design breach, makes each medium runner between the heat transfer plate of being assigned to of homogeneous media.
As preferably, described breach is distributed on the outer of medium through hole of forward heat exchange plate or is distributed on the outer of medium through hole on the reverse heat exchange plate, and the number of described breach is 3-5, star-shaped layout.
The medium throttle structure of the utility model plate type heat exchanger 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.
