Further elaborate as follows below by embodiment and accompanying drawing:
Accompanying drawing 1: the utility model structural representation
Accompanying drawing 2: the utility model fin-type pipe enlarged drawing
Accompanying drawing 3: the straight shape fin-type tube bank of the utility model high-efficiency fin type shell-and-tube heat exchange of heat pipe schematic diagram;
Its structure of the utility model high-efficiency fin type shell-and-tube heat exchange of heat pipe, as shown in Figure 1: constitute by housing and heat exchanger tube core; Its heat exchanger tube core: be made up of fin-type pipe (5) and tube sheet (3), dozens of fin-type pipe (5) is fixed on the tube sheet (3); Its fin-type pipe (5): be made up of fin (14) and heat exchanger tube (13), its fin (14) is vertical straight fins or vertical straight ripple formula fin, as shown in Figure 2; Its housing: form by head (1) and body (6).Its head (1): be that end sealing is semicircle, itself and body connection place are ring flange (10), have dividing plate (12) that its inner chamber is divided into two chambeies up and down in it, promptly high-temperature medium enters chamber C and high-temperature medium outlet plenum D, and its high-temperature medium enters chamber C and is provided with high-temperature medium inlet tube interface (11); High-temperature medium outlet plenum D is provided with high-temperature medium outlet interface (2): its body: be end sealing tubular, establish cryogenic media inlet or outlet duct interface (8), (4) on it, the heat exchanger tube core is housed in the body, itself and head (1), tube sheet (3) connection place are ring flange (9), there is sealing gasket (15) ring flange (10), (9) with tube sheet (3) connection place, by bolt ring flange (10), (9) and tube sheet (3) are connected as one, support (7) are arranged below its body.
Big and small a series of high-efficiency fin type shell-and-tube heats exchange of heat pipe that the inventor makes, its heat exchanger tube core are restrained for the U-shaped fin-type or straight shape fin-type is restrained two kinds, as Fig. 1, shown in Figure 4;
Practice confirms: we compare (one) with traditional light pipe shell-and-tube heat exchanger and the utility model of identical heat exchange area, get the heat exchanger that heat exchange area is 260 square metres and compare, and are listed as follows:
Item argument | Tradition light pipe formula heat exchanger | The finned tube shell-and-tube heat exchanger | The percentage that the finned tube shell-and-tube reduces than light pipe formula |
The housing external diameter | 800mm | 600mm | 25% |
The heat exchanger tube radical | 680 | 168 | 75% |
Heat exchanger tube weight | 3868kg | 2321kg | 40% |
The heat exchanger gross weight | 8410kg | 5040kg | 40% |
As can be seen from the table:
A) the finned tube shell-and-tube heat exchanger is saved space 25% than light pipe formula heat exchanger;
B) finned tube shell-and-tube heat exchanger heat exchanger tube quantity only is 1/4 of light pipe heat exchanger,
Reduced nearly 3/4;
C) the finned tube shell-and-tube heat exchanger is owing to the boring amount of the minimizing tube sheet of pipe has reduced
3/4, heat exchanger tube and tube sheet welding capacity have also reduced 3/4;
D) the finned tube shell-and-tube heat exchanger is owing to the minimizing of volume, at same equal pressure, same
Under the temperature conditions, the tube plate thickness attenuate, ring flange and miscellaneous part are corresponding to be subtracted
Gently, it is nearly 40% that the equipment overall weight of making has descended, the steel of unit heat exchange area
The material consumption has reduced more than 40%.
Because the minimizing of heat exchanger tube, under the condition of same traffic, its high-temperature stream side (being generally high-temperature medium in the pipe) longitudinal finned tube flow velocity can improve nearly four times, improve flow regime widely, improved heat transfer efficiency, opposite, the shell fluid area increases, the pressure that has reduced big discharge capacity one side falls, and can reduce resistance dissipative greatly, energy-conservation 50-80%.
(2) comparison under traditional light pipe shell-and-tube heat exchanger and the high-efficiency fin pipe shell-and-tube heat exchanger volume same case: be 600mm equally with the diameter, the heat exchanger that length is identical is an example, its major parameter such as following table:
Annotate: two kinds of heat exchanger heat-exchanging tubes are arranged and are taked maximum stringing amount to carry out stringing with reference to GB.
Item argument | Tradition light pipe formula heat exchanger | The finned tube shell-and-tube heat exchanger | The finned tube shell-and-tube is the percentage of light pipe formula |
The heat exchanger tube radical | 360 | 168 | -54% |
Heat exchange area | 140 square metres | 260 square metres | +85% |
Heat exchanger tube weight | 2046kg | 2321kg | +13% |
The tube side circulation area | 318 square centimeters | 148 square centimeters | -53% |
Gross weight of equipment | 4640kg | 5040kg | +8% |
To sum up table is as can be seen:
Under the equal volume situation, the heat exchanger tube quantity of high-efficiency fin tubular type heat exchange of heat pipe is lower by 54% than the quantity of light pipe formula heat exchanger, has saved a large amount of heat exchange tube materials, helps the reduction of cost; The tube side circulation area is still low by 53% than light pipe heat exchanger, and under the situation of same traffic, its high temperature fluid flow velocity can improve more than the twice, has improved mixed heat transfer boundary condition, has improved heat exchange efficiency.
High-efficiency fin pipe heat exchanger area has increased by 85% than light pipe formula heat exchanger, its heat exchanger tube weight has only increased by 13%, and (actual heat exchanger tube is to reduce, the just fin weight that increases), gross weight of equipment has only increased by 8%, its unit heat exchange area steel consumption only is 19kg/ square metre, and light pipe heat exchanger steel consumption is 33kg/ square metre, is equivalent to the nearly twice of finned tube exchanger.
In sum, high-efficiency fin type shell-and-tube heat exchange of heat pipe has following advantage:
1) floor space little, in light weight, be specially adapted to the narrow place of construction area.
2) unit heat exchange area steel quantity consumption is low, has reduced steel consumption, has saved valuable natural resources.
3) heat exchange area big (comparing under the equal volume condition), heat exchanger tube is few, has reduced a large amount of machining and welding job amount.
4) increase substantially the flow velocity of heat transferring medium, augmentation of heat transfer improves heat exchange efficiency.
5) profile is the same with the light pipe shell-and-tube heat exchanger, no matter be that new equipment starts, still old plant modification is all very convenient.
6) can be widely used in solution-air, the liquid of industries such as oil, chemical industry, building materials, food
In the heat-exchanger rig of-gas and high-viscous liquid.
Therefore, high-efficiency fin type shell-and-tube heat exchange of heat pipe is a kind of desirable renewal product.
