Abstract
The utility model relates to a heat exchanger with bidirectional helical cantilever type heat exchange pipe. A heat exchange pipe's inlet and outlet of a heat exchanger are fixed on a case, with the middle part in the shape of free suspended arm, and the lead-in section and the outlet section are spiral pipe in different directions. When carrying out the exchange of heat, because of the variation of the pressure and the temperature, the suspended arm's curvature radius of the heat exchange pipe's free end is changed, with driving the entire heat exchange pipe shake endlessly, to make the dirt on the heat exchange pipe drop off. The utility model ensures the exchange of heat succeeded, enhances heat exchanging efficiency, reduces the cost of maintenance, and is widely used for a volumetric heat exchanger, a fast-heating type heat exchanger and a semi-fast heating type heat exchanger.
Description
The utility model relates to a kind of heat exchanger, and specifically a kind of spiral cantilevered coil heat exchanger is the improvement to the spiral coil heat exchanger.
Heat exchanger has been widely used in fields such as industry and daily life, and modal steam heated water heater is exactly a kind of of heat exchanger.Occasion at water for industrial use and domestic water adopts the heat pipe-type interchanger more.Heat exchanger tube in the used for a long time heat exchanger is essentially helical disk tubular type, U-shaped tubular type and shell and tube, the heat exchanger of these forms is because the easy fouling of heat exchanger tube, and influence heat exchanger effectiveness, during use, then need often to clean with snaking, not only influence is used, and waste energy, need a large amount of maintenance costs, will clean once, and cause a large amount of losses in general 1-2 month to the user.
Task of the present utility model is to provide a kind of improved spiral heat pipe exchanger, and its heat exchanger tube is less scaling, to improve the heat exchange efficiency of heat exchanger tube, saves maintenance cost, has overcome the deficiency of prior art.
Task of the present utility model is finished like this.The import and the outlet two ends of the heat exchanger tube of existing heat exchanger are fixed on the housing of heat exchanger, make the middle part of heat exchanger tube be the free arm shape for one section, the two ends of cantilever segment are the inducer of heat exchanger tube and the helical form that outlet section is made different directions, and whole heat exchanger tube is the bidirectional screw cantilevered fashion in heat exchanger.Because the heat exchanger tube both-end is fixed, middle one section is free end, variation along with temperature and pressure, its radius of curvature also changes, thereby drive whole heat exchanger tube shake, like this, when heat exchanger carries out heat exchange, the dirt of giving birth on the spiral cantalever tube is constantly come off, and the assurance heat exchange can be carried out smoothly.Heat exchange efficiency improves, and has also reduced maintenance frequency and has saved expense.
Bidirectional screw arm heat exchange tube design becomes plane bidirectional screw cantalever tube in the utility model, can vertical array or transversely arranged fixing.
Said heat exchanger tube also can be made cylindrical bidirectional screw cantalever tube.
Heat exchanger tube can also be done coning bidirectional screw cantalever tube.
In actual applications, when needs strengthened the heat exchange amount of heat exchanger, the bidirectional screw cantalever tube in this heat exchanger can adopt a plurality of serial or parallel connections to use, and effect is also very desirable.
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing 1 is a structural representation of the present utility model.
Fig. 2 is plane bidirectional screw cantilever heat exchanger tube schematic diagram.
Fig. 3 is cylindrical bidirectional screw cantilever heat exchanger tube schematic diagram.
Fig. 4 is conical bidirectional screw cantilever heat exchanger tube schematic diagram.
Fig. 5 is the A-A cut-away view of Fig. 2.
With reference to accompanying drawing 1 and the embodiment that provides, present embodiment is a steam heated water heater, profile is a tubular, the entrance and exit of cylindrical bidirectional screw cantilevered heat exchanger tube 8 is fixed on the housing, inlet is air intake, outlet links to each other with drain valve (or being called coolant outlet), the middle part of heat exchanger tube 8 is a cantilever end for one section, also can be called free section, be above other two sections of boundary to be inducer with this free section, and following is outlet section, two sections is the helical form of different directions, when the cold water in high-temperature steam feeds heat exchanger tube 8 and heat exchanger carried out heat exchange, along with the variation of temperature and pressure, the free section of heat exchanger tube 8 was flexible, radius of curvature also changes, and drive whole heat exchanger tube shake, the incrustation scale of giving birth on heat exchanger tube is constantly come off, thereby guaranteed carrying out smoothly of heat exchange.So not only improve heat exchanger effectiveness, reduced maintenance time and maintenance cost, guaranteed regular supply life and industrial water.
The utility model is applicable to vapour-hydrothermal exchange, also be suitable for water-hydrothermal exchange, equally also be applicable to the heat exchange of other heat transferring medium, its profile can be horizontal or vertical, being widely used in volumetric heat exchanger, instant heat exchanger and the semi instant heating heat exchanger, is a kind of efficient, energy-conservation, long-life type heat-exchange device.
