Abstract
The utility model relates to a liquid uniform distribution device, and discloses a liquid uniform distribution device for an aluminum plate-fin heat exchanger, which is arranged at an inlet of a passage of the aluminum plate-fin heat exchanger; fluid passages are arranged in the liquid uniform distribution device at intervals, and liquid diversion trenches are symmetrically arranged on the two sides of the liquid uniform distribution device. The liquid uniform distribution device has a simple structure, and can effectively avoid the phenomenon that liquid downwards flows obliquely along the inlet side of the heat exchanger, so as to enable liquid to be uniformly distributed in the passage of the heat exchanger; and the liquid uniform distribution device has higher practicability.
Description
Technical field
The utility model relates to the liquid uniform device, has related in particular to a kind of liquid uniform device that is used for the aluminum plate-fin type heat exchanger.
Background technology
The aluminum plate-fin type heat exchanger is a kind of being applicable to: heat exchange between gas-gas, solution-air, liquid-liquid, the various liquid and the phase-change heat-exchange that phase-state change takes place.During be widely used in empty branch, petrochemical industry, synthetic ammonia, natural gas liquefaction at present and separating etc. installed.Plate-fin heat exchanger is made up of dividing plate, fin, strip of paper used for sealing, flow deflector usually.Between adjacent two dividing plates, place fin, flow deflector and strip of paper used for sealing and form an interlayer, be called passage, such interlayer is stacked according to the different modes of liquid, soldering just composing plate in aggregates bundle, the plate bundle is the core of plate-fin heat exchanger, is also referred to as core body.Core body is equipped with necessary end socket, adapter, support etc. and has just formed plate-fin heat exchanger.Usually the hot fluid trend is for from top to bottom in the plate-fin heat exchanger, and cold liquid moves towards to from bottom to top.When hot liquid is liquid phase or gas-liquid two-phase and flow velocity when low, liquid phase is easy to form bias current when exchanger head gets into core body, makes the whole passage that is assigned to that liquid can not be average, thereby has influence on the heat exchange effect.Therefore need develop a kind of device, solve this technical problem.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, can in the aluminum plate-fin type heat exchanger, realize the equally distributed liquid uniform device of liquid.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
The liquid uniform device that is used for the aluminum plate-fin type heat exchanger, described liquid uniform device is arranged on aluminum plate-fin type heat exchanger passages porch, is arranged at intervals with the fluid passage in the liquid uniform device, and the bilateral symmetry of liquid uniform device is provided with the liquid guide flow groove.Place this liquid uniform device in aluminum plate-fin type heat exchanger passages porch; Can make the low speed liquid phase fluid get under the water conservancy diversion that the aluminum plate-fin type heat exchanger entrance is in the liquid guide flow groove liquid crossflow is moving and be full of guiding gutter; While liquid incoming fluid passage; Liquid gets into the guiding gutter of opposite side through behind the fluid passage, and liquid can get into equably and carry out heat exchange in the thermofin this moment; Therefore can avoid liquid to take place, liquid can be evenly distributed in the heat exchanger channel along the bias current phenomenon that the heat exchanger inlet side flows downward.
As preferably, described fluid passage is arranged on the middle part of liquid guide flow groove.
As preferably, the cross sectional shape of described fluid passage is circle or rectangle.
As preferably, the cross sectional shape of described liquid guide flow groove is circular arc or trapezoidal or rectangle.
The utility model has significant technique effect owing to adopted above technical scheme:
The utility model is simple in structure, can effectively avoid liquid to take place along the bias current phenomenon that the heat exchanger inlet side flows downward, and liquid can be evenly distributed in the heat exchanger channel, has advantages of high practicability.
Description of drawings
Fig. 1 is the layout drawing of the utility model in the aluminum plate-fin type heat exchanger.
Fig. 2 is the A-A face cutaway view of the utility model.
Fig. 3 is the B-B face cutaway view of the utility model.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1 to accompanying drawing 3:
The liquid uniform device that is used for the aluminum plate-fin type heat exchanger; Extremely shown in Figure 3 like Fig. 1; Described liquid uniform device 4 is arranged on aluminum plate-fin type heat exchanger passages porch, is arranged at intervals with fluid passage 41 in the liquid uniform device 4, and the cross sectional shape of fluid passage 41 is circle or rectangle.The bilateral symmetry of liquid uniform device 4 is provided with liquid guide flow groove 42, and the cross sectional shape of liquid guide flow groove 42 is circular arc or trapezoidal or rectangle.Fluid passage 41 is arranged on the middle part of liquid guide flow groove 42.
Fluid gets into from flow deflector 1, behind liquid uniform device 4, liquid is assigned in the fin 5 uniformly, and the 2, the 3rd, strip of paper used for sealing.Fig. 2 is A-A to cutaway view and B-B to cutaway view, among Fig. 2 the 1, the 3rd, and heat exchanger dividing plate, the 2nd, strip of paper used for sealing, the 4th, the utility model liquid uniform device.After the lower liquid of flow velocity is getting into flow-guiding mouth,, will therefore cause the skewness of liquid in heat exchanger to influence the heat exchange effect along Fig. 1 center-aisle to dirty if this liquid uniform device is not set.After the utility model liquid uniform device is housed in the aluminum plate-fin type heat exchanger passages; Like B-B among Fig. 2 to shown in the cutaway view, liquid will be earlier after getting into flow-guiding mouth along the guiding gutter lateral flow and be full of guiding gutter, liquid flows along the V direction simultaneously; Liquid is through behind the fluid passage; Get into the guiding gutter of opposite side once more, liquid can be distributed to equably to get in the heat exchanger and conduct heat this moment, therefore can improve the heat exchange property of heat exchanger.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
