Abstract
The invention relates to a solution of structural design of a supercooling section of a marine shell-and-tube condenser. The invention uses the condensed liquid to enter the supercooling section and carries out heat exchange with water in the heat exchange pipe by back and forth baffling in the flow so as to realize supercooling of the working medium liquid. The structure not only improves the heat exchange efficiency of the condenser, but also reduces throttling loss in actual refrigeration cycle and improves the cycle refrigeration coefficient. The unit has strong applicability and long service life, and is suitable for long-term use of ships.
Description
Technical Field
The utility model relates to a condenser, a high-efficient subcooling shell and tube condenser specifically says so.
Background
In practical refrigeration equipment, liquid subcooling is often employed to improve the performance of the refrigeration system. The sufficient supercooling degree has two major effects: 1. the flash evaporation 2 caused by pressure drop can be avoided, and the vaporization of the refrigerant liquid caused by the heating of the liquid pipe by the environment can be avoided. The usual method for obtaining liquid subcooling: 1. properly increasing the heat exchange area of the condenser 2, increasing the flow rate of the cooling medium or reducing the temperature of the cooling medium 3, utilizing regenerative cycle supercooling 4, utilizing a subcooler supercooling 5, utilizing mechanical supercooling and the like.
However, the common shell-and-tube condenser at present, especially the small condensing device, usually has a simple condensing section structure.
For some small-sized refrigerating devices, a subcooler or a regenerator is additionally arranged to meet the supercooling requirement, and due to the addition of the subcooling equipment, the space utilization rate is reduced, the pipeline arrangement of a system is increased, and the weight and the cost are increased.
Disclosure of Invention
To increase the shortcoming that equipment reaches the subcooling in addition among the prior art, the utility model provides a structure adds singly, can satisfy the subcooling circulation requirement, effectively improves heat exchange efficiency and refrigeration coefficient, is favorable to retrencing refrigeration plant, reduces the refrigeration cost, improves refrigeration system safety and life's high-efficient subcooling shell and tube condenser.
The utility model adopts the technical proposal that: the utility model provides a high-efficient subcooling shell and tube condenser, includes casing, heat exchange tube, and the parallel cross-under of a plurality of heat exchange tubes is in the casing, its characterized in that: the supercooling device comprises a supercooling cladding plate, a left baffle plate and a right baffle plate, the supercooling cladding plate is arranged in the shell in a reverse buckling mode, the supercooling cladding plate is folded downwards along two axial side edges of the heat exchange tube to form side cladding plates, a plurality of groups of left baffle plates and right baffle plates which penetrate through the heat exchange tube are arranged between the supercooling cladding plate and the side cladding plates on the two sides, the top edges of the left baffle plate and the right baffle plates are connected to the supercooling cladding plate, the outer side edges of the left baffle plate and the right baffle plate are respectively connected to the side cladding plates on one side of each, and gaps are reserved between the inner side edges of the left baffle plate and the right baffle plate and the side cladding plates; the lower sides of the left baffle plate and the right baffle plate are in an arc shape attached to the inner wall of the shell.
Further, the side wrapper sheet is supported on the inner wall of the housing.
Furthermore, the front end of the supercooling cladding plate corresponds to the lower part of the upper part of the shell behind the liquid inlet.
The supercooling cladding plate and the side cladding plates at two sides form a semi-enclosed structure, two end parts are semi-open, a plurality of groups of left and right baffle plates are connected to the side cladding plates in a staggered manner, condensed water enters from the open position at the front end of the supercooling cladding, and flows in a snake shape left and right at the left and right baffle plates in the middle to fully exchange heat with the heat exchange tube, so that more effective supercooling degree can be obtained, the structure not only improves the heat exchange efficiency of the condenser, reduces throttling loss in actual refrigeration cycle, improves the circulating refrigeration coefficient, but also does not need to be additionally provided with supercooling equipment, and is beneficial to simplifying refrigeration equipment and reducing refrigeration cost; and the method can effectively avoid the phenomenon that the normal working performance of the expansion valve is damaged due to the fact that the partial liquid refrigerant is gasified because of the pressure loss of the pipeline of the refrigeration system caused by the small supercooling degree, and is beneficial to improving the safety and the service life of the refrigeration system.
