The shell-tube type heat exchanger can greatly improve heat exchanging efficiency, prolong service life, ensure smooth oil return and effectively prevent the coolant from entering into an outer compressor, and maintain high efficiency long time stable operation of the shell-tube type heat exchanger. The shell-tube type heat exchanger has an advantage of reliable design in structure.
Description
Technical field
The utility model belongs to heat-exchange apparatus, is specifically related to the shell and tube heat exchanger of a kind of heat exchange efficiency height, oil return smoothness.
Background technology
Heat exchanger is the ideal equipment that liquid-liquid, liquid-vapour carry out heat exchange.It has that heat exchange efficiency height, heat loss are little, advantages of compact and light structure, floor space are little, install clean make things convenient for, have wide range of applications, characteristics such as long service life.Shell-and-tube exchanger is firm in structure, is easy to make, and adaptability is strong, and disposal ability is big, can also use under high temperature, the high-pressure situations, and heat exchange surface cleans more convenient.This type heat transmission equipment is with the most use in the industry, and historical at most a kind of is prevailing heat transmission equipment.
The structure more complicated of existing shell and tube heat exchanger, the rate of heat exchange of its unit metal is not high, is difficult to satisfy hot season exchange needs efficiently, and can causes damage to compressor.
The utility model content
The utility model provides a kind of reasonable in design, can effectively improve heat exchanger effectiveness, the shell and tube heat exchanger that increases the service life, it can guarantee the oil return smoothness of system, and prevent that effectively liquid refrigerant from entering outside condenser, keep the operation efficient steady in a long-term of shell and tube heat exchanger.
The technical scheme that the utility model adopted is as follows:
A kind of shell and tube heat exchanger, comprise a shell body and heat exchanger coil, the shell body that it is characterized in that described shell and tube heat exchanger has a urceolus and the inner core that is positioned at urceolus, be provided with heat exchanger coil in the described urceolus along simplified axial setting, U type pipe is set in the described inner core, outer tube wall is provided with the water inlet and the delivery port of heat exchanger coil, and the import and export of first cold-producing medium, offers coolant channel on the inner core and communicates with urceolus.
Concretely, the bottom of described U type pipe is provided with an oil return opening, and the end cap of urceolus is stretched out in an end of U type pipe, forms second cold-producing medium and imports and exports.
Described shell body is a columniform urceolus, and the upper and lower side of urceolus is provided with end cap, is provided with the inner core of coaxial setting in the described urceolus, and sealing is provided with between this inner core and end cap.
Described heat exchanger coil is that coiled coil is arranged at the copper pipe in the urceolus, and the water inlet of this heat exchanger coil and delivery port lay respectively at the bottom and the top of outer tube wall.
Described coolant channel is the through hole that is arranged at inner core top.
Described first cold-producing medium is imported and exported the bottom that is positioned at outer tube wall.
This shell and tube heat exchanger adopts the copper pipe of spiral as heat exchanger coil, can improve heat exchanger effectiveness effectively, coolant channel is offered on top at inner core, make inner core when heating, can be used as gas-liquid separator, prevent that liquid flows in the compressor in it, guarantee the steady in a long-term efficient operation of system.The bottom U type bend of U type pipe is provided with oil return opening, can make the oil return smoothness of whole system.
Wherein second cold-producing medium on the U type pipe is imported and exported when this shell and tube heat exchanger refrigeration as the refrigeration machine import, when heating as refrigerant outlet.And the import and export of first cold-producing medium are refrigerant inlet when heating, and are refrigerant outlet when refrigeration.Be that coolant channel is when refrigeration, cold-producing medium enters inner core from second cold-producing medium of the upper end of U type pipe, enter urceolus through inner core upper end through hole, medium in urceolus cold-producing medium and bronze pan tube (as water) carries out heat exchange, be condensed into liquid, import and export from first cold-producing medium of urceolus lower end and discharge.
The beneficial effects of the utility model are, this shell and tube heat exchanger reasonable in design, can improve heat exchanger effectiveness greatly, increase the service life, it can guarantee the oil return smoothness of system, and prevent that effectively cold-producing medium from entering outside condenser, keep the operation efficient steady in a long-term of shell and tube heat exchanger.
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
