Abstract
The utility model provides a kind of coil exchanger being convenient to improve heat exchange efficiency.Existing coil exchanger moves under the effect of the pressure due to the medium in pipe internal and external screw passage, easily produces direct current phenomenon, makes the heat exchange of medium abundant not, causes heat/cold to waste.The utility model comprises housing, one group of spiral coil is provided with inside described housing, the entrance of described spiral coil connecting media one and the outlet of medium one, the two ends of described housing are provided with blind plate, blind plate connecting media two entrance described in side, blind plate connecting media two described in opposite side exports, the inwall of described helix tube is provided with zigzag shape projection, the helical pitch of described zigzag shape projection is not more than 2 times of the internal diameter of described helix tube, and the height of described zigzag shape projection is 0.05-0.15 times of helix tube internal diameter.The utility model makes media for heat exchange more abundant, improves the thermal efficiency of heat exchanger.
Description
technical field:
The utility model relates to a kind of coil exchanger being convenient to improve heat exchange efficiency, belongs to technical field of chemical.
background technology:
Coil exchanger adopts pipe internal channel and pipe outer tunnel to be spiral and gradually opens shape fluid passage, can realize a medium and secondary media and all can reverse, eddy flow advance, carry out heat exchange.This heat-exchanger rig is than spiral-plate heat exchanger under the prerequisite not increasing duct length, and because heat exchange area increases greatly, and because tube wall is thinner, therefore heat exchange efficiency is high, consumptive material is few, compact conformation, small and light, and bearing capacity is high.Be a helical duct in coil Tube Sheet of Heat Exchanger, pipe is outer forms another helical duct, and pipe internal channel walks high temperature, high pressure and have corrosive medium, and pipe outer tunnel walks another kind of medium.Because the medium in pipe internal and external screw passage moves under the effect of the pressure, easily produce direct current phenomenon, make the heat exchange of medium abundant not, cause heat/cold to waste.
summary of the invention:
The purpose of this utility model provides a kind of coil exchanger being convenient to improve heat exchange efficiency for above-mentioned Problems existing, avoid medium in pipe or the outer direct current of pipe, increase resistance and the turbulent flow of media flow, make media for heat exchange more abundant, improve the thermal efficiency of heat exchanger.
Above-mentioned object is realized by following technical scheme:
Be convenient to the coil exchanger improving heat exchange efficiency, comprise housing, one group of spiral coil is provided with inside described housing, the entrance of described spiral coil connecting media one and the outlet of medium one, the two ends of described housing are provided with blind plate, blind plate connecting media two entrance described in side, blind plate connecting media two described in opposite side exports, the inwall of described helix tube is provided with zigzag shape projection, the helical pitch of described zigzag shape projection is not more than 2 times of the internal diameter of described helix tube, the height of described zigzag shape projection is 0.05-0.15 times of helix tube internal diameter.
Described is convenient to the coil exchanger improving heat exchange efficiency, is provided with spacing column between described spiral coil.
Described is convenient to the coil exchanger improving heat exchange efficiency, and the helical pitch of described helix is 0.8-1.5 times of the internal diameter of described helix tube.
Described is convenient to the coil exchanger improving heat exchange efficiency, and the height of described helix is 0.1 times of helix tube internal diameter.
Beneficial effect:
1. the utility model is provided with zigzag shape projection in the inside of helix tube, makes medium increase the resistance of media flow when helix tube internal flow, avoids medium direct current, makes media for heat exchange more abundant, improves the thermal efficiency of heat exchanger.And the present inventor finds through test of many times research, the helical pitch of zigzag shape projection is not more than 2 times of the internal diameter of described helix tube, and when the height of described zigzag shape projection is the 0.05-0.15 times of helix tube internal diameter, turbulence effects is best and be not easy to cause clogging.
2. be provided with spacing column between spiral coil of the present utility model, be convenient to the turbulent flow of the outer medium of reinforced pipe, improve rigidity and the anti-pressure ability of helix tube simultaneously.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1, housing, 2, spiral coil, 3, the entrance of medium one, 4, the outlet of medium one; 5, blind plate; 6, medium two entrance; 7, medium two exports; 8, spacing column.
detailed description of the invention:
Embodiment 1:
