Abstract
The invention discloses a shell and tube heat exchanger which comprises a shell, sheets, heat exchange tubes, a cold fluid inlet, a cold fluid outlet, a hot fluid inlet, a hot fluid outlet and baffles. The sheets are arranged on two inner sides of the shell and divide the shell into a cold fluid flow-in portion, a heat exchange portion and a cold fluid flow-out portion, and the heat exchange tubes which are special-shaped tubes are arranged between the sheets, run through the heat exchange portion and communicate the cold fluid flow-in portion with the cold fluid flow-out portion. Since the heat exchange tubes are special-shaped tubes, heat exchange area is large, heat exchange effect is good, and heat exchange rate of the shell and tube heat exchanger is improved.
Description
Technical field
The present invention relates to heat exchanger, relate in particular to a kind of shell-and-tube exchanger.
Background technology
Shell-and-tube exchanger is a kind of widely used heat exchanger, and it arranges some heat exchanger tubes in the larger extra heavy pipe of diameter, and heat exchanger tube is fixed on the tube sheet at extra heavy pipe two ends, tube loop in forming.Shell-and-tube exchanger by in extra heavy pipe with in interior tube loop, inject different fluids, make between two kinds of fluids and carry out exchange heat, and realize the purposes such as heating or cooling.
But present heat exchanger tube cross section is generally circle, and heat exchange area is more fixing, thereby has affected the rate of heat exchange of shell-and-tube exchanger, the limiter tube shell-type result of use of heat exchanger.
Summary of the invention
The purpose of this invention is to provide a kind of shell-and-tube exchanger with high heat exchange rate.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of shell-and-tube exchanger comprises housing, tube sheet, heat exchanger tube, cold fluid import, cold fluid outlet, hot fluid import, hot fluid outlet and baffle plate, wherein:
Described heat exchanger tube is arranged between the described tube sheet, runs through described heat exchange department, and is communicated with described cold fluid inflow section and cold fluid outflow section, and described heat exchanger tube is shape tube;
Described cold fluid import is arranged on the housing of described cold fluid inflow section, and described cold fluid outlet is arranged on the housing of described cold fluid outflow section;
Described hot fluid import and hot fluid outlet all are arranged on the housing of described heat exchange department, the close described cold fluid outflow of wherein said hot fluid import section, the close described cold fluid inflow of described hot fluid outlet section;
Described baffle plate is arranged on the enclosure interior in described heat exchange space, is between the outlet of described hot fluid import and hot fluid.
Further, the cross section of described heat exchanger tube is oval, semicircle, rectangle or square.
Further, described heat exchanger tube is copper alloy tube.
Shell-and-tube exchanger of the present invention, because heat exchanger tube is shape tube, so heat exchange area is large, good effect of heat exchange, thus improved the rate of heat exchange of shell-and-tube exchanger of the present invention.

The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Specific embodiment described herein is only in order to explaining the present invention, but is not intended to limit the present invention.
As shown in Figure 1, the invention provides a kind of shell-and-tube exchanger, comprise housing 1, tube sheet 2, heat exchanger tube 3, cold fluid import 4, cold fluid outlet 5, hot fluid import 6, hot fluid outlet 7 and baffle plate 8, wherein:
Cold fluid import 4 is arranged on the housing of cold fluid inflow section 9, and cold fluid outlet 5 is arranged on the housing of cold fluid outflow section 11;
Hot fluid import 6 and hot fluid outlet 7 all are arranged on the housing of heat exchange department 10, and wherein hot fluid import 6 is near cold fluid outflow section 11, and hot fluid outlet 7 is near cold fluid inflow section 9;
Baffle plate 8 is arranged on the enclosure interior of heat exchange department 10, is between described hot fluid import 6 and the hot fluid outlet 7.
Shell-and-tube exchanger of the present invention, because heat exchanger tube is shape tube, so heat exchange area is large, good effect of heat exchange, thus improved the rate of heat exchange of shell-and-tube exchanger of the present invention.
Such as Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, according to the specific design mounting condition of heat exchanger, the cross section of heat exchanger tube 3 can be ellipse 12, semicircle 13, rectangle 14 or square 15.
In order to improve further rate of heat exchange, heat exchanger tube 3 is preferably copper alloy tube.
Below in conjunction with accompanying drawing, specify working condition of the present invention.
As shown in Figure 1, at first cold fluid flows into cold fluid inflow section 9 from cold fluid import 4; Cold fluid is by heat exchanger tube 3 subsequently, and the heat exchange department 10 of flowing through flows into cold fluid outflow section 11; Last cold fluid flows out housing 1 by cold fluid outlet 5.When cold fluid flowed, hot fluid flowed into heat exchange department 10 by hot fluid import 6; Along the passage that is separated by baffle plate 8, flow out housing 1 from hot fluid outlet 7 subsequently.Hot fluid and cold fluid carry out heat exchange at heat exchange department 10, because heat exchanger tube 3 is shape tube, so the area of contact hot fluid is large, makes cold fluid more effectively carry out heat exchange with hot fluid, thereby has improved the rate of heat exchange of shell-and-tube exchanger of the present invention.
The above is preferred embodiment of the present invention only, is not to limit practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of claim of the present invention.
