Description
Technical field
The utility model relates to field of heat exchangers, efficiently strengthen spiral winded type heat exchanger more particularly, to a kind of.
Background technique
With the economic development and improvement of people's living standards, the warm air-conditioning of the confession of public building and house has become
Universal requirement.Not only energy utilization rate is low for coal-burning boiler as Chinese tradition heat supply, but also can cause to atmosphere seriously
Pollution, therefore coal-burning boiler is being phased out in some cities, and then operating cost is very high for fuel-oil or fuel-gas boiler.
Summary of the invention
The purpose of this utility model is that solve the deficiencies in the prior art, and a kind of efficiently reinforcing spiral winded type is provided
Heat exchanger.
The new technical solution of the utility model is: a kind of efficiently to strengthen spiral winded type heat exchanger, including tube sheet, center
Bucket, heat exchanger tube and cylinder, the interior middle part of the cylinder are equipped with core barrel, and both ends are equipped with tube sheet, the heat exchanger tube in cylinder
It being spirally wound in core barrel by different level, and heat exchanger tube both ends are fixed on tube sheet, the heat exchange pipe surface is equipped with screw thread, and
Heat exchanger tube is multilayer, each layer heat exchanger tube opposite direction winding, is equipped with backing plate, the plate thickness phase between each layer heat exchanger tube
Together.
The heat exchange tube diameter is 8-21mm.
The heat transfer area of the heat exchanger tube is 100~170 ㎡/m3.
The heat exchange tube fluid passes through in a spiral manner.
The heat exchanger is vertical.
The utility model has the following beneficial effects: the heat transferring medium of the utility model realizes full counter-flow designs, it is energy-saving；It is vertical
The heat exchange efficiency of formula heat exchanger is high, saves occupied area；Compact-sized unit volume has biggish heat transfer area；Reduce wall surface
The trend of fouling；Equipment land occupation is few；It is light-weight, metal consumptive material is few；Hot and cold side difference is small, (cold) thermal energy is fully used, system
Optimized；Equipment has the condition of long-term operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1 being bucket centered on tube sheet, 2,3 be heat exchanger tube, 4 be cylinder.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
A kind of efficiently reinforcing spiral winded type heat exchanger, including tube sheet 1, core barrel 2, heat exchanger tube 3 and cylinder 4, it is described
Middle part is equipped with core barrel 2 in cylinder 4, and both ends are equipped with tube sheet 1 in cylinder 4, during the heat exchanger tube 3 is spirally wound on by different level
On heart bucket 2, and 3 both ends of heat exchanger tube are fixed on tube sheet 1, and 3 surface of heat exchanger tube is equipped with screw thread, and heat exchanger tube 3 is multilayer,
Each 3 opposite direction of layer heat exchanger tube is wound, and backing plate is equipped between each layer heat exchanger tube 3, and the plate thickness is identical.
3 caliber of heat exchanger tube is 8-21mm.
The heat transfer area of the heat exchanger tube 3 is 100~170 ㎡/m3.
Fluid passes through in a spiral manner in the heat exchanger tube 3.
The heat exchanger is vertical.
Spiral winded type heat exchanger tube 3 makes tube fluid continuously change direction during flow forward, in centrifugal force
Under the action of formed perpendicular to main flow direction secondary circulation, enhance the disturbance and turbulence effects in boundary layer, 3 surface of heat exchanger tube is set
There is screw thread, not only increase heat exchange area but also fluid is made to form axial vortex group on entire interface, under low reynolds number i.e.
Strong turbulence effects can be formed, the thickness of laminar sublayer is thinned, rate of heat transfer greatly increases, shorten circulating-heating time etc.,
Improve heat exchange efficiency.
