Abstract
The utility model provides a high efficiency floating head water-water heat exchanger, comprising a pipe box, a shell body, a heat exchange pipe bundle, a floating head, and a pipe plate. The interiors of the pipe box and the shell body of the utility model are respectively provided with a pass partition plate. A tube pass and a shell pass are all divided into two passes. In addition, spiral spoiling ties are arranged in each pipe of the heat exchange pipe bundle, and the pipe plate is of a floating type. The defects of the prior art are overcome by the utility model which has the advantages of large heat exchange coefficient, small thermal stress, and little possibility of leakage. Compared with the other same devices, heat transfer coefficient is increased by 1.3-1.5 times.
Description
The utility model belongs to heat-exchange apparatus, is suitable for using in urban district heating system and other heat transfer system.
The water-water heat exchanger that generally uses is the fixed tube sheet type single-pass exchanger at present, and not only the coefficient of heat transfer is little for it, and easily produces thermal stress, causes leaking.
The purpose of this utility model is, proposes a kind of efficient floating head type water-water heat exchanger, and it can overcome the deficiencies in the prior art part, and not only the coefficient of heat transfer is big, and the thermal stress that produces is little, is difficult for leaking.
The utility model is to realize like this.Efficient floating head type water-water heat exchanger is made of bobbin carriage, housing, heat-exchanging tube bundle, floating head and tube sheet.Be separately installed with a pass partition in heat exchanger bobbin carriage and the housing, the heat exchange shell side and the tube side of heat exchanger is divided into two strokes.Be placed with helical form flow-disturbing tie in each pipe of the heat-exchanging tube bundle of heat exchanger.In addition, the tube sheet of heat exchanger is a relocatable form.
Below by accompanying drawing the utility model is described further.
Accompanying drawing is the front view with broken section of the present utility model, wherein, the 1st, bobbin carriage, the 2nd, housing, the 3rd, heat-exchanging tube bundle, the 4th, raise the nose above water to breathe, the 5th, floating tubesheet, the 6th, bobbin carriage pass partition, the 7th, housing pass partition, the 8th, flow-disturbing tie.Pass partition (6), (7) are divided into two strokes with the heat exchange tube side and the shell side of heat exchanger.Like this, after cold and hot medium entered bobbin carriage (1) or housing (2), it was round mobile to form two journeys under the effect of pass partition (6) and (7), has increased flow velocity, the flow process that extended, and the heat exchange form with full adverse current improves the coefficient of heat transfer greatly.In each pipe of heat-exchanging tube bundle (3), helical form flow-disturbing tie (8) is housed, has changed the liquid form of tube bank (3) inner fluid, make the bigger exothermicity of generation between tube fluid and tube wall, thereby further improved the coefficient of heat transfer.In addition, tube sheet (5) is a relocatable form, thereby makes heat exchanger casing and tube bank, and when being heated or cool off, but free wxpansion or contraction have reduced thermal stress greatly.
Heat-exchanging tube bundle of the present utility model can adopt four kinds of different patterns: 1. common copper pipe; 2. add the flow-disturbing tie in the common copper pipe; 3. common steel tube; 4. add the flow-disturbing tie in the common steel tube.The flow-disturbing tie is spiral-shaped, also can make wave-like or other non-linear shapes.
In a word, the utility model is simple in structure, and is easily manufactured, coefficient of heat transfer height, and the K value can reach 2545W/K.m under normal flow2, (2.88m/s) can reach 4931W/K.m when high flow rate2, to compare with other heat transmission equipment, heat transfer coefficient improves 1.3～1.5 times. Thermal stress is little, is difficult for leaking.
