Alternatively, in the horizontal direction shown in fig. 1 to 4, the orthographic projection of the plurality of baffles when deflected to the maximum angle covers the orthographic projection (i.e., the orthographic projection of the cross section) of the duct 11.
The duct 11 may have an internal hollow structure, and its cross-sectional shape includes, but is not limited to, a circle as shown in fig. 1 to 4, and may also be a polygon such as a rectangle.

In some embodiments, referring to fig. 5 and 6, the heating thick film 13 includes an insulating layer 131, a heating coil 132, and an encapsulation layer (not shown). The insulation layer 131 is provided at least on the outer surface of the pipe 11. The insulating layer 131 serves to electrically insulate the heating coil 132 from the pipe (e.g., the pipe is a metal pipe) 11. The heating coil 132 is disposed on the insulating layer 131 for receiving electricity and generating heat, for example, through a conductive pad. The encapsulation layer is disposed on the insulation layer 131 and covers the heating coil 132, and the encapsulation layer is used to prevent the heating coil 132 from being exposed, so as to prevent the heating coil 132 from being electrically contacted with an external conductive electronic component to form a short circuit.
For scenarios where heating is possible on opposite sides of the heated thick film 13, the heated thick film 13 may include a substrate with heating coils 132 and an encapsulation layer disposed on both sides of the substrate. Optionally, an insulating layer 131 is also provided, for example for an electrically conductive base substrate, the insulation between the base substrate and the heating coil 132 being achieved by the insulating layer 131 being provided between the two.
The encapsulation layer may be directly formed by a film formation method (for example, a sputtering or evaporation method) using an insulating material so as to cover the heating coil 132. It should be understood that the encapsulation layer can also be regarded as a thermal insulation layer, which not only covers the heating coil 132, but also has good thermal insulation performance, and is beneficial for transferring more heat generated by the heating coil 132 to the pipeline and avoiding transferring the heat to the outside of the pipeline.
In other embodiments where the outer surface of the conduit 11 to which the heated thick film 13 is provided is non-conductive, the heated thick film 13 may not be provided with the aforementioned insulating layer 131, but may include a heating coil 132 and an encapsulation layer. Heating coils 132 are provided directly on the outer surface of the pipe 11 for electrical connection and heat generation, for example, by conductive pads. The potting layer is disposed on the outer surface of the pipe 11 and covers the heating coil 132.
The heating thick film 13 may also be provided with conductive pads 134, with the encapsulation layer exposing the conductive pads 134 to allow electrical access to the conductive pads 134. In some embodiments, the surface of the duct 11 may be provided with a terminal plate, one end of which is used for power connection, and the other end of which is electrically connected to the conductive pad 134. In other embodiments, the exposed conductive pads 134 may be directly powered.
It should be understood that the two conductive pads 134 shown in fig. 6 are for exemplary illustration only, and embodiments of the present application do not limit the number of conductive pads 134. For example, the heating thick film 13 may be provided with four conductive pads 134, wherein two conductive pads 134 may be used for power connection, and the other two conductive pads 134 may be respectively connected to two pins of the temperature controller 135, and selectively disconnect the path of the heating coil 132 (between the two conductive pads 134) according to the temperature detected by the temperature controller 135, for example, disconnect the path between the two conductive pads 134 when the heating temperature reaches and exceeds a preset temperature, and keep the path between the two conductive pads 134 connected when the heating temperature is lower than the preset temperature, so as to stop heating.
Referring to fig. 5, 7 to 9, in some embodiments, the steam device 10 further includes a stem 14, the stem 14 is disposed inside the pipe 11, the surface of the stem 14 is provided with an external spiral groove 141, and the external spiral groove 141 and the inner surface of the pipe 11 form a spiral channel. By arranging the core column 14 in the tubular 11, the outer spiral groove 141 of the core column 14 and the inner surface of the tubular 11 form a spiral channel, and the spiral channel prolongs the circulation length and residence time of the steam in the pipeline 11, thereby being beneficial to obtaining more heat from the steam, improving the heat exchange efficiency and increasing the heating speed.
Alternatively, each first spray head 121 is arranged in the outer spiral groove 141 in a direction perpendicular to the stem 14 (for example, in a vertical direction in the orientation shown in fig. 5, 7 to 9), and water sprayed from the first spray head 121 can be in large-area contact with the surface of the stem 14, so that heat can be timely obtained from the stem 14 with good thermal conductivity, and timely generation of steam is facilitated.
The stem 14 may be an integrally formed structural member, and specific implementation forms include but are not limited to: silica gel column, ceramic column or plastic column, etc. The outer surface of the stem 14 may be provided with helical projections 142, which helical projections 142 form an outer helical groove 141. In some embodiments, the distance between the outer spiral grooves 141 decreases gradually along the circulation direction of the steam in the spiral channel, that is, the density of the outer spiral grooves 141 increases gradually closer to the outlet end of the pipe 11, and the larger the circulation length of the steam, the more heat is transferred to the steam per unit time, which is beneficial to increase the heating speed. The density of the outer spiral grooves 141 is smaller closer to the inlet end of the pipe 11, which is beneficial to the rapid circulation of steam inside the pipe 11 and increases the entering amount of the steam.
The steam device 10 may further include a fixing member 143, wherein the fixing member 143 is disposed inside the stem 14, and opposite ends of the fixing member 143 are fixed to sealing structural members (e.g., a first joint and a second joint respectively disposed at two ends of the pipe 11) at two ends of the pipe 11.
In some embodiments, the fixing element 143 may be a bolt, a nut of the bolt is disposed on a side surface of one of the first joint and the second joint facing away from the other joint and abuts against the side surface, and a screw rod penetrates through the other joint and is screwed with the nut. Alternatively, a screw having a screw thread provided on the bolt is screwed with the other of the first joint and the second joint. For example, as shown in fig. 8 and 9, the nut is disposed on a side surface of the second joint facing away from the first joint and abuts against the side surface.
In some embodiments, the outer spiral groove 141 is spaced opposite to the inner surface of the pipe 11 along the radial direction of the pipe 11, a certain gap is left between the outer spiral groove 141 and the pipe 11, and the pipe 11 is not directly in heat conduction contact with the stem 14, so that the stem 14 and the outer spiral groove 141 can be prevented from being burned out when the temperature of the pipe 11 is too high, and the service life of the pipe can be prolonged.
In other embodiments, the diameter of the pipe 11 is gradually reduced along the circulation direction of the steam in the spiral passage, and the outer spiral grooves 141 are abutted against the inner surface of the pipe 11.
Embodiments of the present application also provide a heating device including the steam device 10 manufactured by the method of any of the above embodiments, thereby having corresponding advantages of the steam device 10.
The heating device may be embodied in various specific forms, including but not limited to: air conditioners (such as vehicle air conditioners), electric irons, beauty moisturizing apparatuses, humidifiers, and the like.
