Detailed Description

The technical solutions of the embodiments of the present application are clearly and completely described below with reference to the accompanying drawings, and it is obvious that the following embodiments are only a part of the present application and not all 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 application. 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 an embodiment of the present application, and fig. 2 is a schematic structural view of a heating member according to an embodiment of the present application when it is deployed. As shown in fig. 1 and 2, the tubular heating device 100 includes a tubular member 110 and a heating member 120, the tubular member 110 is a circular tube having a hollow interior, the x direction is a direction of the circular tube around an axis, and the y direction is an axis of the circular tube. The heating member 120 surrounds the outer surface of the tubular member 110 and is in thermal contact with the tubular member 110 such that a heat transfer path is realized between the heating member 120 and the thermal conductive member 110.

As shown in fig. 2, the heating part 120 includes a first heating module 121 and a second heating module 122. The first heating module 121 includes a plurality of first heating units transversely disposed in fig. 2, and the plurality of first heating units are arranged in parallel at intervals along the axial direction of the circular tube, i.e., the y direction. The second heating module 122 includes a plurality of second heating units vertically disposed in fig. 2, and any one of the second heating units extends along the axial direction, i.e., the y direction, of the circular tube. Since fig. 2 is a schematic structural view of the heating member 120 when it is spread out in a plane, a plurality of second heating units are arranged in a direction perpendicular to the y-direction. In addition, two ends of each second heating unit are respectively connected with two adjacent first heating units.

As shown in fig. 2, the heating members 120 may be arranged in a serpentine manner, and the specific number of the first heating units and the second heating units may be set according to the actual requirement. Taking fig. 2 as an example, the first heating module is provided with 16 first heating units, and the second heating module is provided with 15 second heating units. The distances between the first heating units may be equal along the y-direction. The left side of the heating part 120 is distributed with 8 second heating units, and the right side of the heating part 120 is distributed with 7 second heating units.

The length of the first heating unit is far greater than that of the second heating unit, the second heating unit is used for realizing conductive connection between the adjacent first heating units, and the second heating unit also belongs to the heating module. That is, the first heating units can be regarded as the main heating units of the tubular heating device 100, the first heating units are arranged in parallel at intervals, the size of the region where the heating member 120 is arranged is not changed under the condition that the size of the tubular member 110 is not changed, more first heating units can be arranged by controlling the distance between two adjacent first heating units to be as small as possible, and certainly, more second heating units are arranged, so that the area ratio of the heating member 120 on the tubular member 110 can be increased, and the heat conversion efficiency can be improved.

In some embodiments, the first heating module and the second heating module may be made of semiconductor materials, i.e., the first heating unit and the second heating unit may be semiconductor heating units. For example, the first heating module and the second heating module may be made of Indium Gallium Zinc Oxide (IGZO), and thus the first heating module and the second heating module may be made of a heating module using an amorphous semiconductor Oxide technology, and the heating member 120 having the heating module may be designed to be a semiconductor integrated circuit, so that the first heating module and the second heating module have high electron mobility and strong driving capability, and are beneficial to improving the circuit stability.

Of course, the first heating module and the second heating module may also be heating modules using Low Temperature Poly-silicon (LTPS) technology, such as polysilicon (P-Si), so that the heating element 120 having the heating modules may be regarded as a semiconductor integrated circuit design, and the driving power consumption is Low.

In some embodiments, in order to fully utilize the space and further increase the area ratio of the heating member 120 on the tubular member 110, as shown in fig. 2, the heating member 120 further includes a third heating module 123 vertically disposed in fig. 2, and the third heating module 123 includes two upper and lower third heating units. For the design using the electric heating method, the tubular heating device 100 may further be provided with a positive electrode and a negative electrode (not shown in the figure) and two first conductive pads 130, each third heating unit is connected to each first conductive pad 130, one first conductive pad 130 is connected to the positive electrode, and the other first conductive pad 130 is connected to the negative electrode, so as to realize the electric heating.

In some embodiments, as shown in fig. 2, two third heating units may be located at the right side of the heating member 120 and between two outermost (uppermost and lowermost in fig. 2) first heating units, where each third heating unit is connected to one end of the outermost first heating unit and the other end of the outermost first heating unit is connected to one second heating unit. Further, as shown in fig. 2, two third heating units may be arranged along the y direction, and both are located on the same line, which may save space.

In some embodiments, as shown in fig. 1 and 2, the tubular heating apparatus 100 may also be provided with a second conductive pad 140 and a temperature sensor 150. The temperature sensor 150 is electrically connected to the second conductive pad 140. The temperature sensor 150 may detect the current heating temperature for controlling switching of the rapid heating or warm keeping function. As shown in fig. 2, the second conductive pad 140 may be arranged at the left side of the heating member 120, and for convenience of design and circular tube formation of the tubular member 110, the first heating module and the second heating module need to be arranged around the second conductive pad 140, which may result in different lengths of the first heating units. Taking fig. 2 as an example, the lengths of the distal 12 (the upper 6 and the lower 6 in fig. 2) first heating units are equal, and the lengths of the central 4 first heating units are equal, but the former length is greater than the latter length, so as to leave an area for placing the second conductive pad 140. This also results in that of the 8 second heating units on the left side of the heating part 120, the 2 second heating units in the middle are closer to the axis than the other 6 second heating units, and the 7 second heating units on the right side of the heating part 120 can be located on the same straight line.

In some embodiments, the first heating unit, the second heating unit, and the third heating unit may be heating coils which are formed around the outer surface of the tubular member 110 in the aforementioned arrangement using resistive bodies (e.g., wires). As shown by the arrows in fig. 1, the lower end of the tubular member 110 is a fluid inlet, the upper end is a fluid outlet, and the flowing direction of the fluid in the tubular member 110 is from bottom to top, so along the flowing direction of the fluid in the tubular member 110, the greater the number of the first heating units, the greater the number of the second heating units, the greater the density of the heating coils, and the better the heating effect.

It will be appreciated that, with the above-described structural design, the first heating unit, the second heating unit and the third heating unit may also be sheet-like structures, i.e. heating sheets. Compared with a heating coil, the heating area of the heating sheet is large, and therefore the heating sheet is heated quickly under the same energy consumption, and the heating rate is improved.

In some embodiments, the heating member 120 may be in thermally conductive contact with the tubular member 110 by any of film, printing, and winding. The heating member 120 may be attached to the outer surface of the tubular member 110, or may be embedded in the tubular member 110.

The structure and the size of the tubular member 110 and the heating member 120 can be designed according to actual requirements. For example, the tubular member 110 may be a stainless steel pipe.

Another embodiment of the present application provides a heating apparatus including the tubular heating device 100 of any of the above embodiments. The heating device may be embodied in various specific forms, including but not limited to: electric heating kettle, soybean milk machine, milk heating equipment, heat preservation box, etc.

Since the heating apparatus has the tubular heating device 100 of any one of the foregoing embodiments, the heating apparatus can produce the advantageous effects that the tubular heating device 100 of the corresponding embodiment has.
