Abstract
The utility model discloses an air return superheater comprising a cylindrical outer shell body, wherein openings at two ends of the shell body are respectively an inlet and an outlet of refrigerant gas after evaporation, the insides of the two ends of the shell body are provided with baffles, a plurality of holes are arranged in the baffles, a pipe is inserted in each hole, openings at two ends of each pipe are communicated with the openings at the two ends of the shell body, and the plurality of the pipes form a pipe bundle used for the refrigerant gas after the evaporation to pass. An inlet and an outlet of refrigerant gas after condensation are respectively arranged on the pipe wall at two ends of the shell body and on two sides of the pipe wall. The openings at two ends of the shell body shrink. The pipe bundle used for the refrigerant gas after the evaporation to pass is small in pipe diameter and multiple in pipe number. The air return superheater is simple in structure, easy to manufacture, low in production cost, strong in adaptability, good in heat transfer and beneficial for operation of a condenser, prevents liquid shock, improves gas transmission coefficient of the condenser, improves lubrication conditions of the condenser at a low temperature, increases refrigerating capacity per unit, and is suitable for being used in a fluorine refrigerating system.
Description
Technical field
The utility model belongs to technical field of refrigeration equipment, is specifically related to a kind ofly can make the refrigerant gas after condensed refrigerant liquid and the evaporation carry out heat exchange for refrigeration system, realizes that liquid is excessively cold, the return-air superheater device of gas superheat.
Background technology
At present, the high-temperature high-pressure refrigerant gas that refrigeration system is discharged by compressor becomes the cryogenic high pressure refrigerant liquid after condenser condenses, degree of supercooling is usually very little, and may carry a small amount of liquid refrigerant owing to evaporation is insufficient from evaporimeter cold-producing medium out, cause the compressor liquid hammer from face.
The utility model content
The purpose of this utility model is to provide a kind of can maximally utilise the heat exchanger heat exchange; refrigerant gas after can making condensed refrigerant liquid and evaporating carries out heat exchange; realize that liquid is excessively cold, the return-air superheater of gas superheat; thereby improve the refrigerating capacity of system and the COP of refrigeration system, and protection compressor stable operation.
In order to realize this purpose, the technical solution of the utility model is as follows:
A kind of return-air superheater, it comprises that one can make the refrigerant gas cylindrical housing body that carries out heat exchange after condensed refrigerant liquid and the evaporation, refrigerant gas import, the outlet of the opening at housing two ends after for evaporation; The inside at housing two ends is provided with baffle plate, and several perforates are arranged on the baffle plate, is inserted with a pipe in each perforate, and the opening at pipe two ends communicates with the opening at housing two ends, and above-mentioned plurality of tubes subgroup has become the tube bank for the refrigerant gas process after the evaporation; Condensed refrigerant liquid import, outlet are located at respectively on the tube wall at housing two ends, and are positioned at the tube wall both sides.
Further, the opening at described housing two ends slightly zooms in; Described tube bank caliber for the refrigerant gas process after the evaporation is little, and the pipe number is many, and heat exchange area is large.
The beneficial effects of the utility model:
The utility model manufacturing simple in structure, easy, production cost are low, strong adaptability, and heat-transfer effect is good.Be beneficial to compressor operating, prevent liquid hammer; Improve compressor gas transmission coefficient; Improve the lubricating condition of low temperature lower compression machine; Specific refrigerating effect increases.This device is applicable to use in the fluorine refrigeration system.Ammonia does not adopt this backheat circulation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of condensed refrigerant liquid import.
The number in the figure explanation:
1, the refrigerant gas import 2 after the evaporation, baffle plate 3, the outlet of condensed refrigerant liquid
4, tube bank 5, shell 6, condensed refrigerant liquid import
7, the outlet of the refrigerant gas after the evaporation
The specific embodiment
Below come the utility model is described in further detail by specific embodiment.
As shown in Figure 1, a kind of heat-exchanger rig for the refrigeration system return line of the utility model, it is a kind of return-air superheater, it comprises that one can make the refrigerant gas cylindrical housing 5 that carries out heat exchange after condensed refrigerant liquid and the evaporation, the opening at housing two ends slightly dwindles, and the opening at housing two ends exports 7 for the refrigerant gas import 1 after evaporating, the refrigerant gas after the evaporation; The inside at housing two ends is provided with baffle plate 2, and several perforates are arranged on the baffle plate, is inserted with a pipe in each perforate, and the opening at pipe two ends communicates with the opening at housing two ends, and above-mentioned plurality of tubes subgroup has become the tube bank 4 for the refrigerant gas process after the evaporation; Condensed refrigerant liquid import 6, condensed refrigerant liquid outlet 3 are located at respectively on the tube wall at housing two ends, and are positioned at the tube wall both sides; Tube bank 4 calibers of the refrigerant gas process after the described evaporation are little, and the pipe number is many, and heat exchange area is large.
Condensed refrigerant liquid fully carries out heat exchange by the heat transfer of tube wall and the convection current of fluid with the rear refrigerant gas of evaporation inside and outside tube bank, realize that liquid is excessively cold, gas superheat.
As known from the above, the utility model is simple and practical, the utility model is simple in structure, easy manufacturing, production cost are low, thereby has improved specific refrigerating effect, has improved coefficient of refrigerating performance.
The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
