Abstract

The invention discloses a heat exchanger. The heat exchanger comprises a shell, wherein the shell is a hollow barrel; openings are formed in two ends of the shell; a plurality of heat exchanging tubes are arranged in the shell; after being bent respectively in an arc manner, two ends of each heat exchanging tube are fixedly connected to side walls of two ends of the shell; end enclosures are respectively arranged at two ends of the shell and cover connection positions of the heat exchanging tubes and the shell; inner cavities of the end enclosures are communicated with inner cavities of the heat exchanging tubes; and an opening is formed in a side wall of each end enclosure. The heat exchanger is simple in structure and reliable in operation, can be made of various metal structural materials, and is high in heat exchanging effect.

Description

Heat exchanger
Technical field
The present invention relates to a kind of heat exchanger.
Background technology
Heat exchanger is the equipment that the part heat of hot fluid is passed to cold fluid, and heat exchanger is the common apparatus of machinery, chemical industry, oil, power, food and other many industrial departments, occupies aborning critical role.In Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., applies more extensive.Heat exchanger kind is a lot, but substantially can divide three major types according to the principle of cold and hot fluid exchange heat and mode: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, dividing wall type heat exchanger application at most.Existing heat exchanger general structure more complicated, heat transfer effect simple in structure is bad.
Summary of the invention
The technical issues that need to address of the present invention 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 invention 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, on the sidewall of described end socket, is provided with opening.Heat exchanger of the present invention, the opening at shell two ends is import and the outlet of cooling medium, import and outlet that opening on two end sockets is 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, two media can reverse convection, and the design of the arc at heat exchanger tube two ends makes heat transfer effect better.
As the preferred technical solution of the present invention, 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 that bending 90 is spent is more conducive to the buffering of fluid, can reduce flowing velocity, increases the time span of heat exchange.
Heat exchanger of the present invention, structure is simpler, and operation is reliable, the structural material manufacture of available various metal materials, good effect of heat exchange.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is right view of the present invention;
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 the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.
As shown in the figure, heat exchanger of the present invention, 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, on the sidewall of described end socket 3, be provided with opening 4.
Heat exchanger of the present invention, the opening at shell two ends is import and the outlet of cooling medium, import and outlet that opening on two end sockets is 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, two media can reverse convection, and the design of the arc at heat exchanger tube two ends makes heat transfer effect better.The design that bending 90 is spent is more conducive to the buffering of fluid, can reduce flowing velocity, increases the time span of heat exchange.
Heat exchanger of the present invention, structure is simpler, and operation is reliable, the structural material manufacture of available various metal materials, good effect of heat exchange.
