The heater pipes 13 are fixed by an adhesive or solder, so that the heater pipes 13 and the heating plate 11 do not move relative to each other, and heat can be conducted to the bottom wall 121 of the housing portion 12 through the lower surface 1311 of the body portion 131 or to the side wall 122 of the housing portion 12 through the side surfaces 1312 of the body portion 131, and the heat of the heater pipes 13 is further transferred to the heating plate 11, thereby achieving the purpose of heating a medium such as water.
With continued reference to fig. 8 and 12, the heating pipe 13 is provided with a pressing groove 133. Specifically, at least one of the lower surface 1311 and the side surface 1312 of the main body 131 of the heating tube 13 is provided with the pressing groove 133, the pressing groove 133 is formed by die pressing, the die pressing can improve the production efficiency, the lower surface 1311 is provided with a plurality of radial pressing grooves 134 and a plurality of circumferential pressing grooves 135, and two adjacent radial pressing grooves 134 and two adjacent circumferential pressing grooves 135 cooperate together to form the protrusion 132.

The interference fit between the main body 131 and the accommodating part 12 can lead the lower surface 1311 with better flatness to be directly and closely fitted with the bottom wall 121; air bubbles are easily generated between the lower surface 1311 with poor flatness and the bottom wall 121, and due to the existence of the pressing groove 133, the air bubbles are discharged along the pressing groove 133, and the air bubbles and the pressing groove 133 area are adhered or filled with solder, so that the air bubbles between the lower surface 1311 and the bottom wall 121 are reduced as much as possible.

Specifically, the pressing grooves 133 between the protrusions 132 have the same width, and the protrusions are arranged at equal intervals, so that the stability of the solder in the flowing process is facilitated by the pressing grooves 133 with the same width, and the air in the air bubbles can be discharged from the pressing grooves more easily. When the soldering is completed, the solder can easily fill the pressure groove.
In some embodiments, the protrusions 132 are substantially inverted trapezoidal in shape. Specifically, the protrusion on the lower surface 1311 of the main body 131 is formed by two adjacent radial pressing grooves 134 and two adjacent circumferential pressing grooves 135, extension lines of the plurality of radial pressing grooves 134 all intersect with the axis of the heating pipe 13, and the centers of the plurality of circumferential pressing grooves 135 are on the axis of the heating pipe 13. The adjacent two radial pressing grooves 134 are equidistant along the circumferential direction of the heating pipe 13, and the adjacent two circumferential pressing grooves 135 are equidistant along the radial direction of the heating pipe 13.

The length range of the protrusions 132 is 1-2mm, the width range of the protrusions 132 is 1-2mm, and the too small protrusions cause the width of the pressure groove 133 to be too high, so that the ratio of the pressure groove 133 to the outer surface of the heating pipe 13 is high, the area of direct contact between the heating pipe 13 and the heating plate 11 is affected, and further the heat conduction efficiency is affected; an excessively large projection 132 may cause bubbles to form directly on the surface of the projection 132, so that the bubbles cannot contact the indent 133 and be removed.
