It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0040] The heat exchanger body 601 is at least part of the side wall of the heat tank 301, and the heat exchanger body 601 and the heat tank 301 are integrally structured, resulting in good thermal conductivity. Alternatively, the heat exchanger body 601 can be welded or fixed to the side wall or end face of the heat tank 301 by a locking structure, such as bolts. Thermally conductive adhesive can be applied between the heat exchanger body 601 and the heat tank 301 to improve thermal conductivity. In some possible embodiments, the heat exchanger body 601 can be arranged around the outer periphery of the heat tank 301.
[0041] In specific applications, the side wall of the heat tank 301 is provided with an installation groove, and the heat exchanger body 601 is at least partially embedded in the installation groove to facilitate assembly. The heat tank 301 and the installation groove form a multi-faceted contact structure with a large contact surface, resulting in excellent heat conduction and heat exchange effects.
[0042] Alternatively, the sidewall of the heat tank 301 may have an internal mounting cavity, and the heat exchanger body 601 may be disposed within the internal mounting cavity. The sidewall of the heat tank 301 may be a hollow structure, and the heat exchanger body 601 may be at least partially embedded in the internal mounting cavity.
[0043] Alternatively, the heat exchanger body 601 may extend at least partially into the interior of the heat tank 301 for direct contact with the heat exchange medium. The heat exchanger body 601 may be partially disposed outside the heat tank 301 and partially disposed inside the heat tank 301.
[0044] Alternatively, in some possible ways, a heat exchange medium flow channel is formed between the heat exchanger body 601 and the heat tank 301, and the heat exchange medium flow channel may be arranged in a roundabout manner.
[0045] This water supply device integrates a heat tank 301 for storing the heat exchange medium and a heat exchanger body 601. This not only improves the space utilization of the water supply device and reduces its overall volume, but also reduces the number of parts and the overall weight of the device through integrated installation. Furthermore, by integrating the heat tank 301 and the heat exchanger body 601, the heat in the heat tank 301 can be directly transferred to the heat exchanger body 601, thereby improving the high heat exchange efficiency of the heat exchanger body 601.

Furthermore, it prevents moisture from entering, keeping the inside of the water supply equipment dry, reducing dampness and mold growth, and protecting its internal dryness. In addition, flame-retardant insulation cotton is flame-retardant, which can delay the spread of fire to some extent, improving the fire safety of the water supply equipment.

After that, the hot water enters the hot water connecting pipe 2007 through the hot water outlet pipe 6002. Finally, the hot water returns to the hot tank body 301, thus realizing the heat exchange of this water supply device. The hot tank body 301 and the heat exchanger body 601 are integrated and connected. The heat in the hot tank body 301 can be directly transferred to the heat exchanger body 601, thereby improving the high heat exchange efficiency of the heat exchanger body 601.

[0054] The external water entering the thick film heater 701 can enter the heating channel 7006 through the heater connecting pipe 7004. After the thick film heater 701 reheats the external water in the heating channel 7006, the external water is finally output from the drinking water drain pipe 7002.

[0058] Working Principle: During heat exchange in this water supply device, the hot water circulation pump 2006 in the hot water tank and the external drinking water pump 2005 are simultaneously activated.

After exchanging heat with the external water in the heat exchanger body 601, the heat source liquid enters the cold source connector pipe 5001 and then enters the drinking water delivery connecting chamber 5004. After that, the heat source liquid enters the water connecting pipe 2007 through the heat outlet pipe 6002. Finally, the heat source liquid flows back to the heat tank body 301, thereby realizing the heat exchange of this water supply device. The heat tank body 301 and the heat exchanger body 601 are integrated and connected. The heat in the heat tank body 301 can be directly transferred to the heat exchanger body 601, thereby improving the high heat exchange efficiency of the heat exchanger body 601.
[0059] This water supply device integrates a heat tank 301 for storing the heat exchange medium and a heat exchanger body 601.

Furthermore, by integrating the heat tank 301 and the heat exchanger body 601, the heat in the heat tank 301 can be directly transferred to the heat exchanger body 601, thereby improving the heat exchange efficiency of the heat exchanger body 601. Alternatively, at least a portion of the surface of the heat exchanger body 601 can contact the heat tank 301, using direct contact heat conduction, which has excellent heat conduction effect.
