The parts, such as a liquid storing device, a heat exchanger, a liquid separator, etc. Are designed into integration to reduce the assembling space and simplify the pipeline. The barrel wall of an internal barrel is utilized to carry out the heat exchange to enhance the condensation effect and the liquid evaporation effect to obtain the energy-saving effect.

Description

Storage liquid energy-saving exchanger for freezing

The utility model is economized the energy heat exchanger about a kind of the freezing of liquid separation, heat exchange and storage liquid effect that have concurrently with storage liquid and hydrops, especially finger is a kind of is integrated liquid/gas separator, heat exchanger and liquid reservoir etc. in freezing (Tibetan) system, and can provide simplification pipeline and benefit to increase the structure assembly person of result of use.

By present general freezing (Tibetan) system is person as shown in Figure 1, and it includes by elements such as a compressor A, condenser B, liquid reservoir C, switch valve D, heat exchanger E, expansion valve F, evaporimeter G, liquid/gas separator H and is constituted.Wherein, the main function of liquid reservoir C is to store the liquid refrigerants through condenser B cooling back; And the main function of heat exchanger E is to absorb in the evaporimeter G low pressure return pipe not the refrigerant of evaporation fully, make enter the preceding liquid refrigerants condensation temperature of expansion valve F become lower, to increase freezing effect; Again, the main function of liquid/gas separator H is to give the liquids and gases refrigerant that has not evaporation fully that will enter before the compressor A separating liquid, and provide pure vaporizing refrigerant to enter in the compressor, with protection compressor A.As from the foregoing, though liquid reservoir C, heat exchanger E and liquid/gas separator H will provide preferable freezing (Tibetan) effect; But, therefore,, will occupy bigger space to whole assembling space because those element systems are the individuality of independence; And also make the connection of pipeline seem complicated, in maintenance, relatively just comparatively difficult; Again, face must give the coating of heat-insulation layer and isolated with air outside the liquid separator H, produces and the corrosion pedestal otherwise will have water droplet.In view of this, this case creator spy dives through some and grinds, and initiative the utility model, its objective is liquid reservoir, heat exchanger and liquid/gas separator etc. partly are designed to one, and a kind of its assembling space that reduces is provided, simplify its pipeline, and the bucket wall of bucket carries out heat exchange in utilizing, increasing better condensation effect and better liquid evaporation effect, and the constructor who saves the energy.

The utility model is a kind of freezing with storage liquid and hydrops province energy heat exchanger, it is that staving is constituted within being located in the exterior bowl by an exterior bowl and, liquid reservoir by the alternative traditional type of exterior bowl, to store liquid coolant via the condenser cooling, and the liquid/gas separator of the alternative traditional type of mat inner drum, ooze assorted liquid to separate in the vaporizing refrigerant, the bucket wall of bucket in multiple the utilization, carry out heat exchange and can benefit increase the interior refrigerant of the interior refrigerant of inner drum and exterior bowl, separate and reach with having liquid, heat exchange is constructed with a kind of three-in-one element of storage liquid effect, and then reach the assembling space that can make freezing (Tibetan) system and reduce and simplify the linking of pipeline and exempt liquid/gas separator, produce the damaged pipeline of corrosion of water droplet during the running of traditional type refrigeration system, the phenomenon of coolant leakage can be disappeared, the energy spent when originally condensing into water droplet can be saved again, and condensation effect and liquid evaporation separating effect can be increased.

(1) accompanying drawing is partly:

The structure of Fig. 1 generally freezing (Tibetan) system.

The detailed construction cutaway view of Fig. 2 the utility model.

The embodiment schematic diagram of Fig. 3 the utility model.

The second embodiment detailed construction figure of Fig. 4 the utility model.

(2) piece number is partly:

1. exterior bowl 11. input pipes 12. efferent ducts

2. inner drum 21. input pipes 22. efferent ducts

23. capillary spill port 3. condensers 4. switch valves

5. evaporimeter 6. compressors 7. expansion valves

At first see also Fig. 2, it is the detailed construction cutaway view of the utility model, as we know from the figure, the utility model system by one big outside staving 1 and one less within staving 2 constituted.Wherein, inner drum 2 is to be arranged in person in the exterior bowl 1.

Exterior bowl 1 is an airtight staving, is provided with an input pipe 11 and efferent duct 12 on its barrel wall, wherein this efferent duct 12 and extend to bottom within the exterior bowl 1.

Inner drum 2 should be an airtight staving, is that suspention is fixedly arranged on end face on the exterior bowl 1, and its barrel is high be 2/3rds of exterior bowl 1 then, and the bottom of its bottom and exterior bowl 1 is space existence.On inner drum 2, hold and be provided with an input pipe 21 and efferent duct 22, wherein efferent duct 22 is to be KanXing Zhuan to extend in the inner drum 2, and there is a capillary spill port 23 side, bottom of Qian type efferent duct 22, and the cooling matchmaker enters the usefulness of compressor 6, all is all former times to possess with structure institute.

See also Fig. 3, it is the embodiment schematic diagram of the utility model, and as we know from the figure, the input pipe 11 on the exterior bowl 1 will be connected mutually with the output of condenser 3; 12 inputs with switch valve 4 of its efferent duct are connected mutually, can stop 1 by outer bucket and substitute the liquid reservoir of traditional type to store the liquid coolant via condenser 3 coolings.Again as we know from the figure, the input pipe 21 on the inner drum 2 will be connected mutually with the output of evaporimeter 5, and 22 inputs with compressor 6 of its efferent duct are connected mutually, can substitute the liquid/gas separator of traditional type by inner drum, oozes the liquid of mixing in vaporizing refrigerant with separation.When using, flowing into liquid coolant temperature in the exterior bowls 1 from condenser 3 will exceed in the not refrigerant temperature of evaporation fully that flows into from evaporimeter 5 in the inner drums 1, therefore, be stored in exterior bowl 1 interior liquid coolant and will emit heat energy in a large number, and the evaporation refrigerant that is flowed in the inner drum 1 absorbs, and then make liquid coolant produce lower condensation temperature effect from efferent duct 12 outflows of exterior bowl 1, and make in inner drum 2 not fully the deposit liquid of evaporation absorb the refrigerant heat of exterior bowl 1, and carry out more rapid evaporation effect, make to change fully and become gas coolant, gas coolant via efferent duct 22 outflows produced heat effect, wherein, the bucket wall of inner drum 2 will become a bucket wall with heat exchange action.

Please read shown in Figure 4ly again, if when desire is made big exchange heat, inner drum 2 can change over wavy as shown in the figure outer wall, can increase its heat exchange effect.

Address the embodiment shown in the accompanying drawing from upper institute, be not difficult as can be known, the technological means that the utility model used really can reach goal of the invention, and has reduced the space of its assembly element, and has simplified the connection of its pipeline, and because it is the heat exchange that is a substantivity, therefore, really can improve the effect of its heat exchange, and then improve freezing (Tibetan) effect person, and the function of its tool truly has the effect of significant raising article use ability, and it also is unprecedented person in the general ware.
