Abstract

The utility model discloses a heat exchanger which comprises an outer shell. The outer shell is a hollow cylinder with openings at two ends, a plurality of parallel heat exchanging pipes are arranged in the outer shell, and two ends of each heat exchanging pipe are respectively bent in an arc shape and are fixedly connected on side walls at two ends of the outer shell. End enclosures are respectively arranged at the two ends of the outer shell and are covered on connecting positions of the heat exchanging pipes with the outer shell, inner cavities of the end enclosures are communicated with inner cavities of the heat exchanging pipes, and openings are arranged in side walls of the end enclosures. The heat exchanger is simple in structure, reliable in operation and good in heat exchanging effect, and can be made of structural materials of various metal materials.

Description

Heat exchanger
Technical field
The utility model relates to a kind of heat exchanger.
Background technology
Heat exchanger is the equipment of cold fluid that the part heat of hot fluid is passed to, and heat exchanger is the common apparatus of machinery, chemical industry, oil, power, food and other many industrial departments, occupies aborning critical role.Heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc. in Chemical Manufacture, uses more extensive.The heat exchanger kind is a lot, but basically can divide three major types namely according to principle and the mode of cold and hot fluid exchange heat: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, dividing wall type heat exchanger is used at most.Existing heat exchanger general structure more complicated, heat transfer effect simple in structure is bad.
The utility model content
The utility model technical issues that need to address are existing heat exchanger general structure more complicated, and heat transfer effect simple in structure is bad.
For solving the problems of the technologies described above, the utility model provides a kind of heat exchanger, comprise shell, described shell is hollow cylinder, and both ends open, be provided with many parallel heat exchanger tubes in described enclosure, described heat exchanger tube two ends are fixedly attached on the sidewall at described shell two ends after curved bending respectively, be respectively arranged with end socket at described shell two ends, described end socket covers the junction of described heat exchanger tube and shell, and the inner chamber of described end socket communicates with the inner chamber of described heat exchanger tube, is provided with opening on the sidewall of described end socket.Heat exchanger of the present utility model, the opening at shell two ends is import and the outlet of cooling medium, opening on two end sockets is import and the outlet of thermal medium, due to simple in structure, can make the heat exchanger of small volume, but heat transfer effect is than relatively it is bulky better, and two media can reverse convection, and the arc design at heat exchanger tube two ends makes heat transfer effect better.
As optimal technical scheme of the present utility model, the two ends of described heat exchanger tube are fixedly attached on the sidewall at described shell two ends after bending 90 degree respectively, and many described heat exchanger tubes are evenly distributed on the inwall circumference of described shell.The design of bending 90 degree more is conducive to the buffering of fluid, can reduce flowing velocity, increases the time span of heat exchange.
Heat exchanger of the present utility model, structure is simpler, and operation is reliable, the structural material manufacturing of available various metal materials, good effect of heat exchange.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is right view of the present utility model;
Fig. 3 is that the A-A of Fig. 1 is to figure;
Wherein, 1-shell, 2-heat exchanger tube, 3-end socket, 4-opening.
The specific embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with accompanying drawing.
as shown in the figure, heat exchanger of the present utility model, comprise shell 1, described shell 1 is hollow cylinder, and both ends open, be provided with many parallel heat exchanger tubes 2 in described shell 1 inside, and many described heat exchanger tubes 2 are evenly distributed on the inwall circumference of described shell 1, described heat exchanger tube 2 two ends are fixedly attached on the sidewall at described shell 1 two ends after bending 90 degree respectively, be respectively arranged with end socket 3 at described shell 1 two ends, described end socket 3 covers the junction of described heat exchanger tube 2 and shell 1, and the inner chamber of described end socket 3 communicates with the inner chamber of described heat exchanger tube 2, be provided with opening 4 on the sidewall of described end socket 3.
Heat exchanger of the present utility model, the opening at shell two ends is import and the outlet of cooling medium, opening on two end sockets is import and the outlet of thermal medium, due to simple in structure, can make the heat exchanger of small volume, but heat transfer effect is than relatively it is bulky better, and two media can reverse convection, and the arc design at heat exchanger tube two ends makes heat transfer effect better.The design of bending 90 degree more is conducive to the buffering of fluid, can reduce flowing velocity, increases the time span of heat exchange.
Heat exchanger of the present utility model, structure is simpler, and operation is reliable, the structural material manufacturing of available various metal materials, good effect of heat exchange.
