Taking the case that liquid flows in from one end of the tube and flows out from the other end of the tube, the liquid at the lower end of the tube is heated for a short time and at a lower temperature because the liquid just enters the tube body, and the liquid at the upper end of the tube enters the tube body for a long time, is heated for a long time and has a higher temperature. On the basis, the position with lower liquid temperature keeps larger heating power, which is beneficial to heating effect naturally, while the position with higher liquid temperature keeps larger heating power, heat can not be absorbed by liquid effectively, and the heat conversion efficiency is reduced. Especially, when the extreme condition of water shortage occurs, the water shortage can occur at first at the upper end of the tube, and the heating body is dry-burned and easy to burn.

It should be understood that the tubular substrate includes, but is not limited to, circular tubes, elliptical tubes, polygonal tubes, etc., and the main material thereof may be metal, glass, ceramic, etc.
The technical solutions of the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The following embodiments and their technical features may be combined with each other without conflict.
Fig. 1 is a schematic structural view of a tubular heating apparatus according to a first embodiment of the present invention, and fig. 2 is a schematic sectional structural view of the tubular heating apparatus shown in fig. 1. Referring to fig. 1 and 2, the tubular heating device 10 includes a tubular base 11 and a heating element 12, the tubular base 11 is a hollow column structure, the heating element 12 is disposed around the outer surface of the tubular base 11, and the heating element 12 is in contact with the heat pipe 11 to realize a heat transfer path.
For the design using the electric heating method, the tubular heating device 10 may further have a positive electrode and a negative electrode (not shown in the figure), the heating element 12 has two ends along the extending direction of the tubular base 11, wherein one end is located at the upper end of the tubular base 11, the other end is located at the lower end of the tubular base 11, one end of the heating element 12 is connected to the positive electrode, and the other end is connected to the negative electrode.
In an application scenario, the heating element 12 may be a resistance coil (also referred to as a resistance coil), which is formed by surrounding a resistance body (e.g., a conductive trace) on the outer side of the tubular base 11. Along the circulation direction of fluid in the tubular base body 11, the surrounding density of the resistor rings 12 decreases progressively, and as shown in fig. 1 and fig. 2, for the design that the lower end of the tubular base body 11 is a fluid inlet and the upper end is a fluid outlet, the circulation direction of fluid in the tubular base body 11 is from bottom to top, and the surrounding density of the resistor rings 12 decreases progressively from bottom to top, that is, the surrounding distance between two adjacent lowermost resistors is minimum, and the surrounding distance between two adjacent resistors is larger as the distance increases, and the surrounding distance between two adjacent uppermost resistors is maximum.
Based on this, when a positive voltage and a negative voltage are applied to the positive electrode and the negative electrode, respectively, the heat-generating body 12 can be regarded as a resistor, and heat is generated by the voltage drive, and the heat is transferred to the tubular base body 11, thereby heating the fluid located in the tubular base body 11.
In this process, theoretically, the voltage and the current received by each part of the heating element 12 are the same, the heat generated at any position of the heating element 12 is the same, the surrounding density of the resistance coil 12 decreases gradually from bottom to top, the more the heat at the position with the larger surrounding density is, the higher the temperature is, the more the heat at the position with the correspondingly smaller surrounding density is, and the lower the temperature is, therefore, the higher the heating power is kept at the lower end of the tubular substrate 11 with the lower fluid temperature, the lower the heating power is kept at the lower end of the tubular substrate 11 with the higher fluid temperature, which is equivalent to realizing the targeted heating according to the temperature, thereby being beneficial to the effective absorption of the heat generated by heating by the fluid and improving the heat conversion efficiency. In addition, even in an extreme situation of water shortage, the heating power of the upper end of the tubular substrate 11 which is the first to appear water shortage is the lowest, the temperature of the upper end of the tubular substrate 11 is kept in a relatively low state, the heating element 12 is not easy to burn, and the service life of the heating device is prolonged.
In this embodiment, the tubular base 11 may be made of a material with a suitable thermal expansion coefficient, such as a metal material, and when heat is transferred to the tubular base 11, the tubular base 11 thermally expands and is in close contact with the heating element 12, which further facilitates the rapid transfer of heat from the heating element 12 to the tubular base 11. At this time, the outer layer of the heating element 12 should be covered with an insulating layer to achieve insulation between the heating element 12 and the tubular base 11 and to prevent short circuit during heating.
In other embodiments, the outer side of the tubular base 11 may be provided with an insulating and heat conducting layer, which is wrapped around the outer surface of the tubular base 11, in which case, the outer portion of the heating body 12 may not need to be wrapped with an insulating layer. The heating element 12 is arranged around the outer surface of the insulating and heat conducting layer, and here, the heating element 12 and the tubular base 11 are insulated and isolated by the insulating and heat conducting layer, but at the same time, heat conduction can still be realized.
In addition to the above, the resistance coil 12 as the heating device may be provided around the tubular base 11 by any one of film-coating, printing, and winding. The heating element 12 may be attached to the outside of the tubular base 11 or may be embedded in the tubular base 11.
The embodiment of the invention can design the structures and the sizes of the tubular base body 11, the insulating heat conducting layer and the heating body 12 according to actual requirements. For example, the tubular substrate 11 may be stainless steel pipe, and the heat-insulating layer may be an enamel layer or other sprayed heat-insulating layer.
Fig. 3 is a schematic structural view of a tubular heating apparatus according to a second embodiment of the present invention, and fig. 4 is a schematic sectional structural view of the tubular heating apparatus shown in fig. 3. Referring to fig. 3 and 4, the tubular heating device 20 includes a tubular base 21, an insulating heat conducting layer 24, a heating element 22, a positive electrode 231 and a negative electrode 232, wherein the tubular base 21 is a cylindrical structure with a hollow interior, the insulating heat conducting layer 24 is attached to the exterior of the tubular base 21, the heating element 22 is surrounded on the outer surface of the insulating heat conducting layer 24, and herein, the heating element 22 is isolated from the tubular base 21 by the insulating heat conducting layer 24. The heating body 22 is provided with two ends along the extending direction of the tubular base body 21, one end of which is connected to the positive electrode 231 and the other end of which is connected to the negative electrode 232.
The heating body 22 includes a plurality of heating sheets 221 connected in sequence, the heating sheets 221 are arranged around the outer surface of the insulating heat conduction layer 24 in a circle, and the surrounding shape of the heating sheets 221 is the same as the cross-sectional shape of the tubular base body 21, so that the inner side surfaces of the heating sheets 221 are matched with the outer surface of the insulating heat conduction layer 24 and attached to the outer surface. The heat generating sheets 221 are arranged at intervals along the length extending direction of the tubular base body 21, and the distance between any two adjacent heat generating sheets 221 is unequal, that is, the heat generating sheets 221 are not arranged around the outside of the insulating heat conducting layer 24 at intervals. The adjacent heat generating sheets 221 are connected to each other by a sheet-shaped connecting portion 222.
Specifically, the surrounding density of the heat generating sheets 221 decreases in the flow direction of the fluid inside the tubular base body 21. For the design that the lower end of the tubular base body 21 is a fluid inlet and the upper end is a fluid outlet, the flowing direction of the fluid in the tubular base body 21 is from bottom to top, the surrounding density of the heating sheets 221 decreases progressively from bottom to top, that is, the surrounding distance between the adjacent heating sheets 221 at the lowest part is the smallest, and the surrounding distance between the adjacent heating sheets 221 at the highest part is the largest as the surrounding distance between the adjacent heating sheets 221 at the upper part is the larger.
Accordingly, when a positive voltage and a negative voltage are applied to the positive electrode 231 and the negative electrode 232, respectively, the heat generating sheets 221 are regarded as resistors, and generate heat under the driving of the voltages, and the heat is transferred to the tubular base 21, thereby heating the fluid in the tubular base 21.
Similarly, in this process, theoretically, the voltages and currents received by the parts of the heating sheets 221 are the same, the heat generated at any position of the heating body 22 is the same, the surrounding density of the heating sheets 221 decreases from bottom to top, the more the heat at the position with the larger surrounding density is, the higher the temperature is, the more the heat at the position with the correspondingly smaller surrounding density is, and the lower the temperature is, so that the higher the heating power is maintained at the lower end of the tubular base body 21 with the lower temperature, and the lower the heating power is maintained at the lower end of the tubular base body 21 with the higher temperature, which is equivalent to realizing the targeted heating according to the temperature, thereby being beneficial to the effective absorption of the heat generated by heating by the fluid and improving the heat conversion efficiency. In addition, even in an extreme situation of water shortage, the heating power of the upper end of the tubular base 21 which is the first to become water shortage is the lowest, the temperature of the upper end of the tubular base 21 is kept relatively low, the heating element 22 is not easily burnt, and the service life of the heating element is prolonged.
The tubular base 21 may be made of a material with a suitable thermal expansion coefficient, such as a metal material, and when heat is transferred to the tubular base 21, the tubular base 21 thermally expands and is in close contact with the heat generating sheet 221, which further facilitates the rapid transfer of heat from the heat generating body 22 to the tubular base 11 and finally to the fluid to be heated.
The heating element 22 with the above-mentioned structure design can be manufactured by the same process, that is, the heating element 22 is an integrally formed structure manufactured by the same process. Taking an etching process as an example, the embodiment of the invention may first provide a metal sleeve (e.g. a metal cylinder), which can be tightly sleeved outside the insulating and heat conducting layer 24, or coat a whole metal layer outside the insulating and heat conducting layer 24 to form the metal sleeve, then deposit a whole photoresist on the metal sleeve, then expose the photoresist by using a photomask, develop and remove the exposed photoresist to expose the metal sleeve, and leave the unexposed photoresist, then etch and remove the exposed part of the metal sleeve, and leave the part shielded by the photoresist, where the metal sleeve is etched to form a plurality of through holes, which define the heating plate 221, and finally remove the remaining photoresist, and the remained metal sleeve is the heating body 22.
Of course, the heat generating sheet 221 may be disposed around the tubular base 21 by any one of film-coating, printing, and winding. The heating element 22 may be attached to the outside of the tubular base 21 or may be embedded in the tubular base 21.
The positive electrode 231 and the negative electrode 232 may be conductive metal wires, respectively, which are welded to the uppermost and lowermost heat generating sheets 221, respectively.
Compared with a heating wire, the heating area of the heating sheet 221 is large, and compared with a heating film, the area of the heating sheet 221 is small, and the energy consumption required by heating is small, so that the heating sheet 221 can generate heat quickly under the same energy consumption, and the heating rate can be improved.
In the tube heating device of the foregoing embodiment shown in fig. 1 to 4, the heat-generating body exists as a whole, to which only one positive electrode and one negative electrode are connected, whereby the voltage and current applied to any position of the heat-generating body are the same. In order to heat more flexibly and more specifically, according to another embodiment of the present invention, the heating element may include a plurality of sections, the sections are independent from each other, and each section is not connected (or disconnected), one end of each section is used as a positive electrode, and the other end is used as a negative electrode, where the heating element of each section can receive an independent voltage, and the heating temperature of each section can be freely controlled.
The present invention also provides a tubular heating method of an embodiment, as shown in fig. 5, including the following steps S51 and S52.
S51: providing a tubular base body having a flow path inside which a fluid is allowed to flow, and a heat generating body in heat conductive contact with the tubular base body.
S52: and when the fluid flows on the flow path of the tubular base body, controlling the heating power of the heating body to be gradually reduced along the flowing direction of the fluid.
