Abstract
The utility model discloses a refrigerant distribution device of a flooded evaporator. The refrigerant distribution device of the flooded evaporator is located on the bottom of an inner cavity of the evaporator and exactly faces a refrigerant inlet. The refrigerant distribution device of the flooded evaporator comprises a rectangular distribution plate, distribution holes are formed in the distribution plate, and the distribution holes are arranged in a row in the distribution plate in the transverse direction. The distribution holes are located at the two ends of the distribution plate and are arranged in bilateral symmetry. According to the refrigerant distribution device of the flooded evaporator, the distribution plate is arranged, the distribution holes in the distribution plate enable liquid refrigerants to enter the flooded evaporator more evenly, the temperature of all positions of a heat exchange tube in the evaporator is made to be even, heat exchange efficiency can be improved, and thus energy consumption can be lowered.
Description
Technical field
The utility model relates to flooded evaporator field, particularly a kind of cooling medium distributor that improves the flooded evaporator of evaporimeter heat exchanger effectiveness.
Background technology
Evaporimeter is the indispensable part in refrigeration plant, and flooded evaporator is a kind of of evaporimeter.Refrigerant changes gas form into by liquid form in flooded evaporator, absorption refrigeration, and then refrigerant is recycled in the middle of compressor.Refrigerant enters flooded evaporator from refrigerant entrance, and liquid refrigerants there will be and distributes uneven phenomenon, causes heat exchanger effectiveness low, waste energy.
Summary of the invention
The utility model provides a kind of cooling medium distributor of flooded evaporator, makes the distribution of liquid refrigerants more even, improves heat exchanger effectiveness.
For technical solution problem, the utility model is taked following technical scheme:
A cooling medium distributor for flooded evaporator, is positioned at the bottom of evaporimeter inner chamber, is right against refrigerant entrance.The cooling medium distributor of described flooded evaporator comprises rectangle distribution plate, and distribution plate is provided with dispensing orifice, and dispensing orifice is in a row transversely arranging of distribution plate.
Described dispensing orifice is positioned at the two ends of distribution plate, and is symmetrically arranged.
Described dispensing orifice is provided with a plurality of, and the cross-sectional area of dispensing orifice mind-set two ends from distribution plate increase progressively gradually.
The cross section of described dispensing orifice is rectangle or circle.
The two ends of described distribution plate are fixedly connected with gripper shoe, and gripper shoe is fixed on the inwall of evaporator shell.
The utility model is by distribution plate is set, and the dispensing orifice on distribution plate can make liquid refrigerants enter more uniformly in flooded evaporator, makes the temperature equalization everywhere of heat-exchange tube in evaporimeter, improves heat exchanger effectiveness, thereby reduces energy consumption.
Accompanying drawing explanation
Fig. 1 is that the utility model is installed on the structural representation in evaporimeter;
Fig. 2 is the cross-sectional view of Fig. 1;
Fig. 3 is the structural representation of distribution plate in the utility model.
Number in the figure is depicted as: 1-housing, 2-refrigerant entrance, 3-refrigerant exit, 4-refrigerating medium entrance, the outlet of 5-refrigerating medium, 6-distribution plate, 61-dispensing orifice, 7-gripper shoe, 8-heat-exchange tube.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, Figure 2 and Figure 3, a kind of cooling medium distributor of flooded evaporator, is positioned at the bottom of evaporimeter inner chamber, is right against refrigerant entrance 2.Flooded evaporator comprises the housing 1 of horizontal layout, refrigerant entrance 2 is positioned at the bottom of housing 1, refrigerant exit 3 is positioned at the top of housing 1, the end of housing 1 is provided with the outlet 5 of entrance 4 and the refrigerating medium of refrigerating medium, the inner chamber of housing 1 is provided with heat-exchange tube 8, and heat-exchange tube 8 is communicated with refrigerating medium entrance 4 and refrigerating medium outlet 5.
The cooling medium distributor of flooded evaporator comprises rectangle distribution plate 6, and the two ends of distribution plate 6 are fixedly connected with gripper shoe 7, and gripper shoe 7 is fixed on the inwall of evaporator shell 1.Distribution plate 6 is provided with dispensing orifice 61, and dispensing orifice 61 is in a row transversely arranging of distribution plate 6.Dispensing orifice 61 is positioned at the two ends of distribution plate 6, and is symmetrically arranged, can symmetery when liquid refrigerants is entered.Dispensing orifice 61 is provided with a plurality of, and the cross-sectional area of dispensing orifice 61 mind-set two ends from distribution plate 6 increase progressively gradually.The center of distribution plate 6 is near refrigerant entrance 2, liquid refrigerants enters evaporator shell 1 when interior, dispensing orifice 61 place liquid body pressure close to refrigerant entrance 2 are large, flow for balanced liquid refrigerants, dispensing orifice 61 cross-sectional areas close to refrigerant entrance 2 arrange a little bit smallerly, a long way off arrange more greatly.The cross section of dispensing orifice 61 is that rectangle also can be set to circle.
The course of work of flooded evaporator: first liquid refrigerants enters in housing 1 from refrigerant entrance 2, under the effect of distribution plate 6, the dispensing orifice 61 of liquid refrigerants from distribution plate 6 upwards flows, balanced distribution, liquid refrigerants submergence heat-exchange tube 8.Refrigerating medium enters in heat-exchange tube 8 by refrigerating medium entrance 4, flows out after cooling by refrigerant by heat-exchange tube 8 from refrigerating medium outlet 5.After liquid refrigerants heat absorption, evaporation is converted into gaseous state, and gaseous coolant flows to compressor from refrigerant exit 3.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, is not departing under the prerequisite of inventive concept of the present utility model, and any apparent replacement is all within protection domain of the present utility model.
