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 front view of a tubular heating device according to an embodiment of the present application. As shown in fig. 1, the tubular heating apparatus 100 includes a tubular member 110 and a semi-arc heating member 120. The tubular member 110 is a hollow pipe having a flow path for flowing a fluid therein. The semi-arc heating member 120 is disposed around the tubular member 110 and on a side close to the flow path. The semi-arc heating member 120 is in thermal conductive contact with the tubular member 110 such that a heat transfer path is achieved between the semi-arc heating member 120 and the tubular member 110.

In fig. 1, the tubular member 110 is transversely disposed, as indicated by the arrows in fig. 1, the right end of the tubular member 110 is a fluid inlet, the left end is a fluid outlet, and the fluid flows through the tubular member 110 from right to left. A flow path for fluid circulation is provided at the bottom (not shown in the figure) of the tubular member 110. To improve heating efficiency, the semi-arc shaped heating element 120 is wrapped around the bottom of the tubular member 110, close to the flow path, to better heat the fluid. Moreover, the heating member 120 has only a half arc shape, and does not need to surround the tubular member 110 for a circle, which can save cost.

In some embodiments, the tubular member 110 and the semi-arc heating member 120 have an insulating layer (not shown) therebetween. The insulating layer has a thermal conductive property, and therefore, the insulating layer can be in thermal conductive contact with the tubular member 110 and the semi-arc heating member 120. The insulating layer is disposed between the tubular member 110 and the semi-arc heating member 120, so that the voltage or current applied to the semi-arc heating member 120 can be prevented from being transmitted to the tubular member 110, which may affect the heating efficiency. It is also possible to prevent the heat generated from the semi-arc heating member 120 from burning the tubular member 110.

FIG. 2 is a schematic view of the semi-arc heating element in an expanded view according to an embodiment of the present application. As shown in fig. 2, the y-direction is the direction of fluid flow within the tubular member 110 (right to left). The semi-arc heating member 120 includes a plurality of semi-arc heating strips 121, and the plurality of semi-arc heating strips 121 are all disposed around the tubular member 110 and located at one side close to the flow path. The middle of two adjacent semi-arc heating strips 121 are connected in series by a short heating strip to form a semi-arc heating component 120.

In some embodiments, as shown in fig. 1, the tubular member 110 is a cylindrical pipe with a uniform radius, and as shown in fig. 2, the semi-arc heating strips 121 have the same radius and length. Thus, the appearance is attractive, and the design is convenient.

In some embodiments, the tubular member 110 may be a trapezoidal pipe with a thicker first end and a thinner second end, and the radius and length of the plurality of semi-arc heating strips 121 decrease from the first end to the second end.

Assuming that the left end is the first end of the tubular member 110 and the right end is the second end of the tubular member 110, as shown in fig. 3, the surrounding radii and lengths of the plurality of semi-arc heating strips 121 decrease from left to right. This not only better conforms to the shape of the tubular member 110, but also saves on the cost of the heating strips.

In some embodiments, as shown in fig. 2 and 3, the two adjacent semi-arc heating strips 121 are spaced at the same distance, which is more convenient for design and also for controlling the heating power.

In some embodiments, the spacing between two adjacent semi-arc heating strips 121 may also increase or decrease in the direction of the flow path. Namely, the heating power is gradually increased or gradually reduced by adopting the step-type heating, so that the energy consumption can be saved, and the heating power can be better controlled and adjusted. As shown in fig. 4, from right to left, the smaller the pitch between two adjacent half arc heating strips 121 is, the heating power of the half arc heating strips 121 sequentially increases in the direction of the flow path.

In some embodiments, the semi-arc heating strip 121 may be a heating coil that is formed around the outer surface of the tubular member 110 using a resistive body (e.g., a wire). The higher the density of the heating coil, the better the heating effect. It is understood that the semi-arc heating strips 121 may also be 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 and/or heating fins of the plurality of half-arc heating strips 121 increases or decreases in the direction of the flow path. If the heating power of the plurality of half-arc heating strips 121 increases progressively along the direction of the flow path, the density of the heating coils and/or the heating sheets increases progressively along the direction of the flow path; if the heating power of the plurality of half-arc heating bars 121 decreases in the direction of the flow path, the density of the heating coils and/or the heating fins decreases in the direction of the flow path.

In some embodiments, the semi-arc heating strips 121 may be made of a semiconductor material, i.e., the semi-arc heating elements 120 may be semiconductor heating elements. For example, the semi-arc heating strips 121 may be Indium Gallium Zinc Oxide (IGZO), and thus, the semi-arc heating components 120 may be heating components adopting an amorphous semiconductor Oxide technology, and a heating thick film formed by the semi-arc heating components 120 and peripheral circuits thereof may be considered as a semiconductor integrated circuit design, so that the semi-arc heating strips have high electron mobility and strong driving capability, and are beneficial to improving circuit stability.

Of course, the semi-arc heating bar 121 may also be a heating element using Low Temperature Poly-silicon (LTPS) technology, such as polysilicon (P-Si), so that the heating thick film formed by the semi-arc heating element 120 and its peripheral circuits can be regarded as using 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 (not shown), each of which is disposed near one of the half-arc heating strips for detecting a heating temperature of each of the half-arc heating strips, so as to control the heating temperature. If the heating power is abnormal, which half arc-shaped heating strip is abnormal can be known through the reading of the temperature sensor.

The structure and the size of the tubular member 110 and the semi-arc 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.
