Abstract
The utility model discloses a small-gap screwed tube heat exchanger, which comprises a housing, four flange interfaces respectively fixed at the top end and the bottom part of the housing, and heat exchanging tube bundles fixed in the housing, wherein a fixing tube is arranged in the center of the interior of the housing, and the heat exchanging tube bundles are crossed in a plurality of layers and wound in a spiral manner by taking the fixing tube as the center. The utility model has the beneficial effects that the heat exchanging tube bundles are crossed in a plurality of layers and wound in a spiral manner by taking the fixing tube as the center, and the gaps among the heat exchanging bundles are very small, so that the heat exchanger can be made into very small volume, and the heat exchanging volume is very large, the heat exchanging efficiency is high, and the energy utilization rate is increased.
Description
Technical field
The utility model relates to a kind of heat exchanger of chemical pharmaceutical process, and particularly a kind of little clearance thread heat exchange of heat pipe is used for the vapour-liquid heat exchange, is applicable to the condensation of organic materials, utilizes Steam Heating material or water.
Background technology
Mostly existing heat exchanger is shell-and-tube heat exchanger, and half is straight tube for a heat exchanger tube, causes the interior heat exchange volume of equal volume less, can't guarantee heating and condensation effect, because of its heat exchange efficiency is low, causes the huge waste of the energy.In order to improve the heat exchange efficiency of heat exchanger, those skilled in the art have carried out deep research, what generally adopt at present is bellows, band pipe, convergent-divergent pipe, screwed pipe etc., yet because traditional arrangement mode is still adopted in the arrangement of these heat exchanger heat-exchanging tubes, heat exchange efficiency improves little.
Summary of the invention
Problem to be solved in the utility model is: the little clearance thread heat exchange of heat pipe that a kind of volume is little, heat exchanger effectiveness is high and energy utilization rate is high is provided.
In order to solve the problems of the technologies described above, little clearance thread heat exchange of heat pipe of the present utility model, comprise housing, be separately fixed at four flange-interfaces in housing top and bottom and be fixed on the interior heat-exchanging tube bundle of housing, the center of described enclosure interior is provided with stationary pipes, and described heat-exchanging tube bundle is that center multilayer cross-helicity twines with the stationary pipes.
In order further to increase the volume of heat exchange, little clearance thread heat exchange of heat pipe of the present utility model, described heat-exchanging tube bundle are to be made by elongated thin-walled screw thread metal pipe.
Little clearance thread heat exchange of heat pipe of the present utility model, the diameter of described elongated thin-walled screw thread metal pipe is 8mm, 10mm or 12mm.
The beneficial effect that the utility model is obtained is: described heat-exchanging tube bundle is that center multilayer cross-helicity twines with the stationary pipes, gap between the heat-exchanging tube bundle is very little, thereby it is very little to make that heat exchanger volume can be done, and the heat exchange volume is big, and the heat exchanger effectiveness height also improves rate of energy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, flange-interface, 2, housing, 3, heat-exchanging tube bundle, 4, stationary pipes.
The specific embodiment
Embodiment 1
