A heating apparatus for heating a fluid according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a heating device for heating fluid according to an embodiment of the present invention includes a heater, a heat-conductive outer sleeve 1.

The heater comprises a heat conduction pipe 2 and a heating component 3; the heating component 3 is tightly attached to the inner wall of the heat conducting pipe 2, and the heat generated by the heating component is transferred outwards through the heat conducting pipe 2. In one embodiment, the heating component 3 is a heating wire, which is installed inside the heat pipe 2 and closely attached to the inner wall of the heat pipe 2, and when the heating wire is powered on, the heat generated by the heating wire is transferred to the outside through the heat pipe 2. It should be understood that the heating member 3 may also adopt other suitable structures, which are not listed here.

The heat conduction outer sleeve 1 is sleeved on the heat conduction pipe 2, and the outer peripheral wall of the heat conduction pipe 2 forms a spiral groove 4. The inner peripheral wall of the heat-conducting outer sleeve 1 is closely adjacent to the outer peripheral wall of the heat-conducting pipe 2, and the two together form a spiral heating channel for the fluid to be heated to flow. When the heater block 3 generates heat, the fluid flowing through the heating channel can be heated, because the inner wall of the heating channel is composed of the groove wall of the groove 4 and the part of the groove opening of the groove 4 covered in the inner peripheral wall of the heat conduction outer sleeve 1, the heater block 3 transfers the heat to the heat conduction pipe 2, the part can directly transfer the fluid flowing through the heating channel, the heat conduction efficiency is high, the working temperature of the heater does not need to be set to be higher, the ideal use effect can be achieved, and the service life of the heater is further ensured.

In one embodiment, the heater is a single-head electrothermal tube, and the outer peripheral wall of the single-head electrothermal tube forms a spiral groove 4.

The cross-sectional shape of the groove 4 may be semicircular, rectangular, or other suitable shape. Preferably, the cross-sectional shape of the groove 4 is rectangular.

The number of the heating channels can be adjusted according to the actual use condition, that is, the number of the grooves 4 can be adjusted according to the actual use condition. For example, when the heating device is applied to a stage smoking machine, the number of the heating channels can be only 1 when only the smoke oil needs to be heated and atomized to generate smoke. For another example, when two different fluids need to be heated separately at the same time, the number of the heating channels may be 2, and the heating channels are arranged in parallel.

In this embodiment, the heating device further includes a liquid inlet channel 5 and a liquid outlet channel 6, and the liquid inlet channel 5 and the liquid outlet channel 6 are respectively communicated with two ends of the heating channel.

Specifically, both ends of the heat-conducting outer sleeve 1 are fixedly connected with the heat-conducting pipe 2 by adopting sealing welding. The heat conduction outer sleeve 1 forms a liquid inlet through hole 7 and a liquid outlet through hole 8 which are respectively communicated with two ends of the heating channel, the liquid inlet channel 5 and the liquid outlet channel 6 are fixedly connected with the heat conduction outer sleeve 1, if the liquid inlet channel 5 is fixedly welded, the liquid inlet channel 5 is communicated with one end of the heating channel through the liquid inlet through hole 7, and the liquid outlet channel 6 is communicated with the other end of the heating channel through the liquid outlet through hole 8.

Referring now to fig. 4 and 5, in another embodiment, the inner peripheral wall of the outer heat-conducting sleeve 1 forms a helical stop 9 adjacent to the outer edge of at least one side wall of the groove 4. The baffle part 9 is additionally arranged, so that the transverse transfer of fluid in the flowing process of the heating channel can be avoided. Preferably, the stops 9 abut the outer edges of both side walls of the groove 4 at the same time. The heat-conducting outer sleeve 1 can be rotatably installed to enable the heat-conducting outer sleeve 1 to be sleeved on the heat-conducting pipe 2.

In the embodiment of the utility model, when the heating component 3 generates heat, the fluid flowing through the heating channel can be heated, and as the inner wall of the heating channel consists of the groove wall of the groove 4 and the part of the inner peripheral wall of the heat-conducting outer sleeve 1 covering the notch of the groove 4, the heat transferred to the heat-conducting pipe 2 by the heating component 3 can be directly transferred to the fluid flowing through the heating channel, the heat conduction efficiency is high, the working temperature of the heater does not need to be set higher, the ideal use effect can be achieved, and the service life of the heater is further ensured.
