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 plurality of heating members 120, the tubular member 110 is a circular tube having a hollow interior, the x direction is an axial direction of the circular tube, and the y direction is an axial direction of the circular tube. The plurality of heating members 120 are disposed around the outer surface of the tubular member 110 and in thermal contact with the tubular member 110, such that a thermal transfer path is realized between the plurality of heating members 120 and the thermal conductive member 110.

In some embodiments, the heating power of each heating element 120 is individually controlled, and a plurality of heating elements 120 are arranged in parallel and at intervals along the axial direction of the circular tube, i.e., the y direction. Each heating element 120 is individually controlled, so that the heating power of each heating process can be individually controlled according to the fluid property or other actual conditions during the whole heating process of the fluid, so as to heat the fluid better and improve the heating efficiency.

In some embodiments, each heating component 120 is connected to a separate power source. As shown in fig. 2, taking two heating elements 120 as an example, the upper heating element 120 is controlled by a power supply V1, and one end of the upper heating element is connected to the positive electrode of the power supply V1, and the other end of the upper heating element is connected to the negative electrode of the power supply V1. The lower heating member 120 is individually controlled by a power supply V2, one end of which is connected to the positive electrode of the power supply V2 and the other end of which is connected to the negative electrode of the power supply V2. The voltage of the power source V1 and the voltage of the power source V2 may be different or the same.

In some embodiments, to save energy consumption, stepwise heating, i.e. gradually increasing or gradually decreasing the heating power, may be used during the entire heating of the fluid. Correspondingly, the heating power of the plurality of heating elements 120 increases or decreases along the axial direction of the circular tube, i.e., the y direction.

In some embodiments, the heating member 120 may be a heating coil formed by surrounding an outer surface of the tubular member 110 with a resistive body (e.g., a wire). 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 fluid flowing direction in the tubular member 110 is from bottom to top, so that the heating effect is better when the density of the heating coils is higher along the fluid flowing direction in the tubular member 110.

It is understood that the heating member 120 may also have a sheet-like structure, i.e., a heating sheet. 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 density of the heating coils or fins increases or decreases along the axis of the tube. If the heating power of the plurality of heating members 120 increases in the y direction, which is the axial direction of the circular tube, the density of the heating coils or the heating sheets increases in the axial direction of the circular tube; when the heating power of the plurality of heating members 120 decreases in the y direction in the axial direction of the round tube, the density of the heating coils or the heating fins decreases in the axial direction of the round tube.

In some embodiments, as shown in fig. 2, each heating member 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 first heating units are arranged in 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, each heating component 120 may be regarded as being arranged in a serpentine manner, and the specific number of the first heating unit and the second heating unit of each heating component 120 may be set according to the actual requirement. Taking fig. 2 as an example, the first heating module of each heating member 120 is provided with 10 first heating units, and the second heating module is provided with 9 second heating units. The distances between the first heating units may be equal along the y-direction. 5 second heating units are distributed on the left side of each heating component 120, and 4 second heating units are distributed on the right side.

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 cross-sectional area of each first heating unit is equal, and the cross-sectional area of each second heating unit is equal, i.e. the thickness of the heating units is the same, which is more convenient for design.

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 as a semiconductor integrated circuit, and has high electron mobility and strong driving capability, thereby being beneficial to improving the stability of the circuit.

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, the tubular heating apparatus 100 further comprises a plurality of temperature sensors 130, and each temperature sensor 130 is disposed near the first heating module and the second heating module of one of the heating members 120 for detecting the heating temperature and facilitating the control of the heating temperature.

As shown in fig. 2, the uppermost 4 first heating units and the lowermost 4 first heating units of each heating member 120 have the same length, and the middle 2 first heating units have the same length, but the former length is longer than the latter length, so that an area is left for placing the temperature sensor 130, thereby saving space. This also results in that of the 5 second heating units on the left side of each heating member 120, the 1 second heating unit in the middle is closer to the axis than the other 4 second heating units, and the 4 second heating units on the right side can be located on the same straight line.

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.
