Abstract
The utility model relates to a high efficiency heat exchanger, which is mainly used for the vapor-liquid and liquid-liquid heat exchange of a chemical industry, a light industry, industrial and civil building, etc. The high efficiency heat exchanger is mainly characterized in that a laminar flow proof device is arranged inside a heat exchanging pipe. The laminar flow proof device disturbs the flow direction of a medium in a pipe pass to increase the capability of turbulent flow when the high efficiency heat exchanger of the utility model disturb is used, the laminar flow phenomenon of the fluid of the pipe pass is stopped, and thereby, the heat exchange efficiency is greatly enhanced. The high efficiency heat exchanger of the utility model has easy manufacture, low cost, convenient examination and maintenance, and convenient cleaning.
Description
Technical field
The utility model high-performance heat exchanger relates generally to field vapour-liquid, liquid-liquid, vapour-vapour heat exchange such as Chemical Manufacture, light industry production, worker China Democratic National Construction Association.
Background technology
The main heat exchanger of Chemical Manufacture is common tubular heat exchanger, corrugated tube heat exchanger, fluted tube heat exchanger, screwed tube heat exchanger and lamella heat exchanger etc. at present, and its structure is referring to Fig. 1, Fig. 2 in the Figure of description, and wherein I is a partial enlarged drawing among Fig. 1.There is following shortcoming in these several heat exchangers:
1. though common tubular heat exchanger cost is low, fluid flows in tube side and forms laminar flow easily, is formed centrally obvious thermograde in heat exchange tube wall and the heat exchanger tube, and heat exchange efficiency is low.
2. corrugated tube heat exchanger, fluted tube heat exchanger and screwed tube heat exchanger heat exchange efficiency increase about 1.5～2 times than common tubular heat exchanger, but the cost height, difficulty of processing is big.Along with the time lengthening, foreign material in the fluid and silt can be in tube wall groove depositions in addition, and this will influence heat exchange efficiency greatly.
3. though lamella heat exchanger heat exchange efficiency height, the gap is little between the plate, and the impurity after operation a period of time in the fluid will stop up the fluid passage, and heat exchange efficiency descends significantly.
Summary of the invention
The utility model high-performance heat exchanger overcomes the various drawbacks of above several heat exchangers, and heat exchange efficiency can significantly be improved, and easy to process, assembling is simple, cost is low.
The technical scheme of the utility model high-performance heat exchanger mainly comprises: bobbin carriage, housing, tube sheet, tubulation, fixture and deflection plate; Its feature is fixed an anti-laminar flow apparatus in heat exchanger tube.
Above-mentioned new type high efficient heat exchanger, described anti-laminar flow apparatus can be fixed in the heat exchanger tube for board-like shape in the shape of a spiral.
Above-mentioned new type high efficient heat exchanger, described anti-laminar flow apparatus hurricane band is installed in the heat exchanger tube, and two is separately fixed on the tube sheet.
Above-mentioned new type high efficient heat exchanger, the form of further taking of described anti-laminar flow apparatus can be the imperial device of motorless hinge.
Above-mentioned new type high efficient heat exchanger, described anti-laminar flow apparatus can be the screws along the axis distribution that is fixed in the heat exchanger tube.
Above-mentioned new type high efficient heat exchanger, described anti-laminar flow apparatus can be the helical fins along the axis distribution that is fixed in the heat exchanger tube.
Adopt the new type high efficient heat exchanger of said structure to upset tube side medium flow direction, increase turbulent flow power, stop tube side fluid laminar flow phenomenon, thereby increase substantially heat exchange efficiency.

The specific embodiment
In conjunction with the accompanying drawings a kind of embodiment of the utility model is described in further detail:
The utility model heat exchanger mainly is made up of bobbin carriage 1, tube sheet 2, cylindrical shell 3, heat exchanger tube 4, deflection plate 5, anti-laminar flow apparatus 6, sees shown in Figure 3; Heat exchanger tube 4 can adopt stainless steel seamless pipe, also can adopt the pipe of various types such as bellows, helix tube, fluted tube; Anti-laminar flow apparatus 6 can adopt stainless steel band to make, stainless steel band is made helical form by certain pitch of waves t, pitch of waves t formulates according to flow rate of fluid is different, one end of helical steel band is wideer than heat exchanger tube, so that be stuck on the heat exchanger tube, the stainless reinforcing bar device 7 that fixes is worn in other end punching, prevents that this anti-laminar flow apparatus 6 from heat exchanger tube 4 internal vibrations, seeing shown in Figure 6; Row's heat exchanger tube 4 can use a reinforcing bar to fix on the tube sheet 2, sees shown in Figure 7.Anti-laminar flow apparatus 6 also can adopt the imperial device of motorless hinge, can also be for being fixed on screw, the helical fin along a reinforcing bar distribution of axis in the heat exchanger tube.Can both obtain heat exchange effect preferably.
