As shown in fig. 9, fig. 9 shows a guiding flow path of the welding slag between the heat conducting disc 120 and the metal base disc 110 on the heat conducting disc 120, wherein the direction indicated by the arrow represents the flow direction of the welding slag. The guiding description of the welding slag when the heat conducting disc 120 is brazed with the metal base disc 110 is as follows: the heat conducting tray 120 is provided with a slot (a first groove 121) for fixing the heating tube 20, and the other side of the heat conducting tray is provided with a convex hull which is arranged in the slot (a second groove) of the metal base tray 110; the second groove is a full circle of U-shaped groove, the lower part of the U-shaped groove is semicircular, and two sides of the U-shaped groove are provided with corresponding inclination angles; the bottom of the semicircular arc of the metal base disc 110 is the lowest part, the bottom of the semicircular convex hull of the heat conducting disc 120 is the lowest part, and welding slag between the metal base disc 110 and the heat conducting disc 120 can be guided and drained through the through hole of the accommodating part and is accumulated in the accommodating part; meanwhile, the welding slag generated on the planes of the heat conducting disc 120 and the metal base disc 110 is guided and drained through the plurality of notches 123, so that no welding slag is generated between the heat conducting disc 120 and the metal base disc 110, internal stress is evacuated, and the metal base disc 110 and the heat conducting disc 120 are free of hollowing, seamless, good in heat conduction and uniform in heating, so that excessive noise cannot be generated, and the effects of stable noise and noise reduction and silence are achieved.

In some embodiments, as shown in fig. 1-5, 8 and 9, the disk body 10 includes: a metal base plate 110, wherein a second groove is arranged on the bottom surface of the metal base plate 110; the heat conducting disc 120 is connected to the bottom surface of the metal base disc 110, the first groove 121 is arranged on the bottom surface of the heat conducting disc 120, the first groove 121 is matched with the second groove, and the second groove is positioned in the first groove 121; the receiving portion 122 is a through hole penetrating the heat conductive plate 120.

In these embodiments, the metal base plate 110 may serve as a kettle bottom, the heat conducting plate 120 for conducting heat is disposed between the metal base plate 110 and the heating tube 20, the heat of the heating tube 20 is conducted to the heat conducting plate 120 first, and then conducted to the metal base plate 110 via the heat conducting plate 120, the heat conducting plate 120 can make the heat generated by the heating tube 20 more uniformly transferred, and the violent generation and breakage of bubbles are reduced, thereby reducing the noise in the water boiling process, and avoiding the problem that only one circle of the kettle bottom in contact with the heating tube 20 has the highest temperature and other parts have lower temperatures, and meanwhile, the heat of the heating tube 20 can be uniformly transferred to other positions of the metal base plate 110, so as to achieve uniform heating of the metal base plate 110. Further, the accommodating part 122 is a through hole penetrating through the heat conducting disc 120, so that the accommodating part 122 can guide and overflow welding slag between the heating tube 20 and the heat conducting disc 120 and between the heat conducting disc 120 and the metal base disc 110, and disperse and guide out stress generated in the high-temperature brazing process, so that the heating tube 20 and the heat conducting disc 120, the heat conducting disc 120 and the metal base disc 110 are free of hollowing after being welded, seamless and good in heat conductivity.

Of course, the containing part 122 can also be the blind hole of setting on the heat conduction dish 120, set up the containing part 122 into the blind hole, also can play the effect that the welding slag between heating tube 20 and the heat conduction dish 120 leads and spills over to carry out sparse derivation to the stress that the high temperature brazing process produced, make heating tube 20 and heat conduction dish 120 welding back do not have the hollowing, seamless, the heat conductivity is good, the heating is even, thereby improve noise stability, promote the silence effect of making an uproar.

Further, in some embodiments, as shown in fig. 3, 5, and 7, the outer surface of the first groove 121 conforms to the inner surface of the second groove; the heat generating tube 20 is attached to the inner surface of the first recess 121. So set up, heating tube 20 and the internal surface of first recess 121 are laminated mutually, and the zero clearance, the external surface of the first recess 121 of heat conduction dish 120 and the second recess internal surface of metal base plate 110 are laminated mutually also, and the zero clearance, consequently can be with the heat that heating tube 20 produced effectively fast pass to the first arch 111 outer wall of metal base plate 110, and then heat the water in the kettle fast balancedly.

In some embodiments, as shown in fig. 1, 2, 4, 6 and 9, the heat conducting disc 120 is provided with a plurality of notches 123 at the outer peripheral edge thereof, which extend inward from the outer peripheral edge, and the notches 123 penetrate through the heat conducting disc 120 in the thickness direction of the heat conducting disc 120. With such an arrangement, the notch 123 can guide and overflow and accommodate welding slag and stress generated during welding between the heat conduction disc 120 and the metal base disc 110, and prevent irregular overflow of the welding slag from affecting welding between the metal base disc 110 and the container body 40.

It can be understood that, when the heat conducting disc 120 is welded to the metal base disc 110, some hot air may be generated to form internal stress, if the internal stress is accumulated, a gap and a hollow drum may be formed between the heat conducting disc 120 and the metal base disc 110, the heat conductivity is poor, the heating is not uniform, the noise is very large, and the welding slag and the stress generated during the welding between the heat conducting disc 120 and the metal base disc 110 are guided to overflow through the notch 123, so that no hollow drum, no gap and good heat conductivity can be ensured after the heat conducting disc 120 is welded to the metal base disc 110.

In some embodiments, as shown in fig. 1, 2, 4, 6, and 9, the plurality of notches 123 are evenly distributed along the circumferential direction of the thermally conductive disk 120. By such arrangement, welding slag generated during welding between the heat conduction disc 120 and the metal base disc 110 can be distributed more uniformly, and gaps and hollows between the heat conduction disc 120 and the metal base disc 110 due to local accumulation are avoided.

In some embodiments, as shown in fig. 1, 2, 4, 6 and 9, the plurality of notches 123 escape from the circumferential position of the heat-conducting disc 120 corresponding to the accommodating portion 122 and are uniformly distributed along the circumferential direction of the heat-conducting disc 120. With such an arrangement, the installation position of the notch 123 avoids the circumferential edge of the heat conducting disc 120 corresponding to the accommodating portion 122, and the accommodating portion 122 can also play a role in guiding welding slag and stress between the heat conducting disc 120 and the metal base disc 110, so that the notch 123 arranged near the accommodating portion 122 can be eliminated, and the structural strength of the heat conducting disc 120 can be enhanced. The notches 123 are uniformly distributed along the circumferential direction of the heat conducting disc 120, so that welding slag generated during welding between the heat conducting disc 120 and the metal base disc 110 can be more uniformly distributed, and the phenomenon that the heat conducting disc 120 and the metal base disc 110 have gaps and empty drums due to local accumulation is avoided.

Further, the number of the notches 123 may be 3 to 60, the number of the notches 123 is less than 3, the effect of balancing the welding slag and the welding stress is poor, and the flow guiding is poor, so that the welding slag is easily accumulated locally to cause a gap and a hollow bulge between the heat conducting disc 120 and the metal base disc 110; however, if the number of the notches 123 is more than 60, the heat conducting plate 120 is complicated to form and difficult to process, and the circumferential edge of the heat conducting plate 120 has a poor structural strength and is easily deformed or damaged.

As an example, optionally, as shown in fig. 1, fig. 2, fig. 4, fig. 6, and fig. 9, the number of the notches 123 is 11, and as shown in fig. 4, the spacing angle β between two adjacent notches 123 is about 30 °, so that a good flow guiding effect can be ensured, and the heat conducting disc 120 is not complicated in structure and difficult to process. And the notch 123 is disposed to avoid the circumferential edge of the heat conductive plate 120 corresponding to the receiving portion 122, so that the structural strength of the heat conductive plate 120 can be enhanced.

In some embodiments, the notch 123 is any one of triangular, rectangular, scalloped, and semicircular. So set up, triangle-shaped, rectangle, fan-shaped, semi-circular not only can play the effect of water conservancy diversion, still have the shape rule, the advantage of the processing production of being convenient for.

Of course, the present disclosure is not limited thereto, and it can be understood that, according to the specific structural design layout of the chassis assembly, a person skilled in the art can also correspondingly design the notch 123 to be in a pentagonal shape or even in other irregular pattern shapes, and specific situations in this respect are not listed here, but all of them belong to the protection scope of the present disclosure without departing from the design concept.

In some embodiments, as shown in fig. 4, the extension a of the notch 123 from the outer peripheral edge of the heat conducting disc 120 to the bottom of the notch 123 is greater than or equal to 1mm and less than or equal to 20mm.

In these embodiments, if the length a of the gap 123 is less than 1mm, the gap 123 is inconvenient to form, and the diversion effect is poor, so that the welding slag cannot be deposited; on the other hand, if the length a of the gap 123 is greater than 20mm, the area of the heat conductive plate 120 and the metal base plate 110 is increased, and the material is wasted.

As an example, alternatively, as shown in fig. 4, the length a of the notch 123 is preferably 5mm, easy to form, has enough space for storing welding slag generated by welding, and does not waste space, material, etc. due to an excessively long length.

In some embodiments, as shown in fig. 4, the notch 123 has a triangular shape or a fan shape, a width of the notch 123 in the circumferential direction of the heat conducting plate 120 gradually increases from a bottom of the notch 123 to an outer peripheral edge of the heat conducting plate 120, and an included angle α between two sides of the notch 123 is greater than or equal to 10 ° and less than 180 °.

In these embodiments, the notch 123 is configured to be triangular or fan-shaped, so that two side edges of the notch 123 are inclined from inside to outside gradually toward the direction of enlarging the notch 123, thereby having a flow guiding effect and being more beneficial to discharging the internal welding slag gradually through the notch 123; further, as shown in fig. 4, an included angle α between two side edges of the notch 123 is greater than or equal to 10 ° and smaller than 180 °, and the included angle α smaller than 10 ° has a problem of difficult molding, and the notch 123 is difficult to process, and the notch 123 has a small volume and a poor flow guiding effect due to too small included angle α, and cannot store welding slag; the included angle α larger than 180 ° also results in a complex shape of the notch 123, inconvenient molding and inconvenient flow guiding.

As an example, as shown in fig. 4, the included angle α between the two sides of the notch 123 is preferably 30 °, which is convenient for machining, has good flow guiding effect, and has enough space for storing welding slag generated by welding.

In some embodiments, the receiving portion 122 is any one of rectangular, circular, oval, fan-shaped, and triangular. So set up, rectangle, circular, oval, fan-shaped, triangle-shaped not only can play the effect of water conservancy diversion, still have the shape rule, the advantage of the processing production of being convenient for.

Of course, the present invention is not limited to this, and it can be understood that, according to the specific structural design layout of the chassis assembly, a person skilled in the art may also correspondingly design the accommodating portion 122 to be in a pentagonal shape or even in other irregular pattern shapes, and specific cases in this respect are not listed here, but all of them belong to the protection scope of the present invention without departing from the design concept.

In some embodiments, the area of the receiving portion 122 is 9mm or more ² And is less than or equal to 450mm ² . Within this range, on the one hand, the accommodating portion 122 can be ensured to have a sufficient space for storing the welding slag generated by welding, and on the other hand, the problems that the space is wasted due to an excessively large area of the accommodating portion 122 and the heat conductive plate 120 is easily damaged due to an excessively low structural strength are not caused.

In some embodiments, as shown in fig. 4, the accommodating portion 122 is rectangular, the length L of the accommodating portion 122 is greater than or equal to 3mm and less than or equal to 30mm, and the width W of the accommodating portion 122 is greater than or equal to 3mm and less than or equal to 15mm.

In these embodiments, the rectangular through-hole guide has a large area and the slag deposit space is the largest, and therefore, the rectangular through-hole is preferable. Furthermore, the length L of the rectangular accommodating part 122 can be selected to be 3-30mm and less than 3mm, so that the rectangular accommodating part is inconvenient to form, the through hole is small, welding slag is inconvenient to flow and guide, and the space for storing the welding slag is small; and more than 30mm, the unheated area in the first groove 121 is too large, and the liquid in the container body 40 is heated unevenly. The width W of the rectangular accommodating part 122 can be 3-15mm and is smaller than 3mm, so that the rectangular accommodating part is inconvenient to form, a through hole is small, welding slag is inconvenient to flow, and the space for storing the welding slag is small; more than 15mm, the strength of the heat conducting plate 120 is weak and is easy to deform.

As an example, the length L of the rectangular through hole is preferably 15mm, which can ensure that there is an electrical gap and a safety distance of 12.7mm between the cold pins 220 at the two ends of the heat-generating tube 20, and at the same time, the area in the first groove 121 that cannot be heated is small, and the liquid in the container body 40 is heated more uniformly; the width W of the rectangular through hole is preferably 11-12mm, and the rectangular through hole is matched with the pipe diameter of the heating pipe 20, so that the forming is most convenient.

In some embodiments, as shown in fig. 2 and 4, the heat generating tube 20 includes a tube body 210 capable of generating heat and cold needles 220 located at two ends of the tube body 210, and the accommodating portion 122 is located between the two cold needles 220 and disposed away from the tube body 210; a first end of cold pin 220 is connected to tube 210, and a second end of cold pin 220 extends obliquely away from disk body 10.

In these embodiments, the accommodating portion 122 is disposed between the two cold pins 220 and disposed away from the tube body 210, which increases the contact area between the tube body 210 and the first groove 121, that is, increases the heat exchange area between the heat generating tube 20 and the heat conducting plate 120, compared to disposing the accommodating portion 122 below the tube body 210, and improves the heat exchange efficiency. Further, the second end of cold needle 220 extends towards the direction slope that is kept away from dish body 10, namely, the second end of cold needle 220 slightly downward sloping under normal use condition, more makes things convenient for the spot welding of inside lead wire fixed like this, has reserved corresponding electric clearance and creepage distance simultaneously, has promoted the security of product.

In some embodiments, as shown in fig. 1, 2, 3 and 6, the tray body 10 is provided with a plurality of threaded posts 130, and the thermostat or the like is locked in the threaded posts 130 by a fastener. So set up, directly lock the temperature controller on the screw thread post 130 of the dish body 10, be favorable to the installation of isoelectronic device such as temperature controller.

Optionally, the outer diameter of the metal base disc 110 is 60mm to 250mm, preferably 125mm; the power meets the corresponding safety standard, generally 100W-1800W, preferably 1500W; the outer diameter of the heat generating tube 20 is 75% of that of the metal base plate 110, and the diameter of the heat generating tube 20 in the embodiment is preferably 95mm. SUS316 and SUS304 are selected as the material of the metal base 110, and SUS304 is preferred because SUS316 is expensive.
