Abstract
The utility model discloses a spiral screw thread wound heat exchanger used for a hot water and heat supply system heat exchange machine set, which comprises a pipe case, and the upper end of the pipe case is connected with a hot medium inlet and a cold medium outlet; the lower end of the pipe case is connected with a hot medium outlet and a cold medium inlet; a spiral screw thread wound pipe bundle is positioned in the pipe case; the upper end of the spiral screw thread wound pipe bundle is connected with the hot medium inlet, the lower end of the spiral screw thread wound pipe bundle is connected with the hot medium outlet, and the middle part of the spiral screw thread wound pipe bundle is a heat exchange pipe wound layer. The spiral screw thread wound heat exchanger adopts spiral wound structure, greatly alters fluid flow state, forms strong turbulence effect and greatly enhances heat transfer film coefficient. The flow speed is high; the temperature grads is small; the dirt coefficient is small; the scaling tendency is low; the noise is lower than 10 db; the heat exchange coefficient can reach the highest 14000w/m<2> DEG C; the volume is small; the area occupation is small; the volume is only one-tenth of the volume of the existing heat exchanger, and the spiral screw thread wound heat exchanger can achieve the same heat exchange effect.
Description
Technical field
The utility model relates to the heat exchanger in a kind of heat supply water, the heating system heat exchange unit.
Background technology
Known shell-and-tube heat exchanger is bulky, and the coefficient of heat transfer is low, and inner wall of tube shell is coarse relatively, rate of flow of fluid is more slow, the dead angle too much, make whole fouling of heat exchangers tendency increase greatly.Clean behind the fouling of heat exchangers difficulty, since shell side with the material difference of tube side, generally can't carry out chemical cleaning, can only adopt machinery or manually scale removal, operation is numerous and diverse, expense is high; And big because of volume, the scale removal time is increased, expense improves; Noise is big, is not suitable for the residential block.
Summary of the invention
The purpose of this utility model provides the screw coiled heat exchanger that volume is little, less scaling and noise is little.
The purpose of this utility model is achieved in that this heat exchanger comprises shell, the upper end of shell is connected with heating agent import and refrigerant exit, the lower end of shell is connected with heating agent outlet and refrigerant import, screw twines tube bank and is positioned at shell, screw twines the tube bank upper end and links to each other with the heating agent import, screw twines the tube bank lower end and links to each other with the heating agent outlet, and intrafascicular of screw winding pipe is heat exchanger tube coiling layer.
Angle between described heating agent outlet and the refrigerant import is 100 °.
The utility model all participates in heat exchange, does not stay the dead angle, makes fluid wash away pipeline automatically, and convection cell plays cushioning effect, reduces noise.The countercurrent flow of media of both sides has been realized the flow velocity height, and thermograde is little, sealing factor is little, and fouling tendency is low.Volume is little, and floor space is little, and volume has only 1/10th of existing heat exchanger volume, but can reach same heat exchange effect.The spiral winding structure of heat exchanger tube has changed fluid flow state greatly, forms strong turbulence effects, has improved film coefficient of heat transfer greatly.Steam stops in heat-exchanging tube bundle for more time, condensation is abundant more and need not pass through secondary heat exchange, so can save a large amount of steam.Shell, heat-exchanging tube bundle and flange are austenitic stainless steel weldering system, and antiseptic property is good, and the life-span is long, can be applicable to the multiple fluid medium.Shell volume maximum can reach 4.2 times of pipe volume.Effectively suppressed the sound standing wave vibrations, noise is lower than 10 decibels, does not almost have noise.The coefficient of heat transfer is the highest can to reach 14000w/m
2. ℃, energy-efficient, safe and reliable, the life-span can reach 40 years, and maintenance cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.1. refrigerant exits among the figure, 2. heating agent import, 3. refrigerant import, 4. heating agent outlet, 5. screw twines tube bank, 6. stainless steel shell, 7. heat exchanger tube coiling layer, 8. angle.
The specific embodiment
In Fig. 1, this heat exchanger comprises stainless steel shell 6, the upper end of stainless steel shell 6 is connected with heating agent import 2 and refrigerant exit 1, the lower end of stainless steel shell 6 is connected with heating agent outlet 4 and refrigerant import 3, screw twines tube bank and is positioned at stainless steel shell 6, screw twines the tube bank upper end and links to each other with heating agent import 2, and screw twines the tube bank lower end and links to each other with heating agent outlet 4, and intrafascicular of screw winding pipe is heat exchanger tube coiling layer 7.Angle 8 between heating agent outlet 4 and the refrigerant import 3 is 100 °.
Claims (2)
1. screw coiled heat exchanger, this heat exchanger comprises shell, the upper end of shell is connected with heating agent import and refrigerant exit, the lower end of shell is connected with heating agent outlet and refrigerant import, it is characterized in that screw twines tube bank and is positioned at shell, screw twines the tube bank upper end and links to each other with the heating agent import, and screw twines the tube bank lower end and links to each other with the heating agent outlet, and intrafascicular of screw winding pipe is heat exchanger tube coiling layer.
