Water heaters and vehicles

[0001] This application claims priority to the Chinese patent application filed on November 28, 2023, with application number 202311604383.9, and invention name “Water Heating Heater and Vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to a water heating heater and a vehicle. Background Art

[0003] In related technologies, the thermal output of PTC (Positive Temperature Coefficient) water heaters is significantly affected by the flow channel, whose structure influences the flow resistance and heat transfer capacity of the flowing medium. When the heat transfer capacity is low, the heat emitted by the PTC heating element cannot be promptly carried away by the flowing medium, increasing the resistance of the PTC heating element and significantly reducing the heating output of the PTC water heater, affecting product performance and thermal efficiency. Furthermore, low thermal efficiency of the PTC water heater consumes more power from hybrid and electric vehicles, reducing the range of these hybrid and pure electric vehicles.

Each water tank 1 is provided with an inlet channel 11, an outlet channel 12, and multiple branch channels 13 connected between the inlet channel 11 and the outlet channel 12. One of the water tanks 1 is also provided with a heater water inlet 14 and a heater water outlet 15. Each of the inlet channels 11 is connected to the heater water inlet 14, and each of the outlet channels 12 is connected to the heater water outlet 15.

[0046] A heating component 2 is provided between two adjacent water tanks 1 .

[0047] In the water heater provided in the embodiment of the present application, the flow medium enters the interior of the water heater through the water inlet 14 of the heater, and is diverted to the water inlet channel 11 of each water tank 1 in a parallel manner. After the flow medium exchanges heat with the heating component 2 in the branch channel 13, it flows to the water outlet channel 12, and finally converges to the heater outlet 15 and is discharged outside the water heater. By providing multiple water tanks 1, the flow channels in the water heater are layered, and branch channels 13 are added at the same time, so that the laminar flow channels and branch channels 13 are arranged in parallel, which balances the flow rate of the medium fluid, avoids excessive local temperature, improves the heat exchange effect, and improves thermal efficiency.

[0048] In one embodiment, as shown in Figure 6 , branch flow channels 13 within the same water tank 1 are arranged in parallel, perpendicular to the predetermined direction. Within the same water tank 1 , flow is split between two adjacent branch flow channels 13 via a diverter plate 3 . The branch flow channels 13 within each water tank 1 are connected in parallel to direct the fluid from the inlet flow channel 11 into the outlet flow channel 12 , ensuring sufficient heating of the fluid and improving heating efficiency.

[0049] Preferably, on the same water tank 1 , the widths of the branch flow channels 13 are equal, and the branch flow channels are M-shaped to uniform the flow velocity and reduce the flow resistance.

[0050] In the embodiments shown in Figures 1 to 6, two branch flow channels 13 are provided on the same water tank 1. The two branch flow channels 13 are arranged in parallel and have equal widths. In other embodiments not shown in the figures, the same water tank may also have other numbers of branch flow channels besides two, such as three or four. The number of branch flow channels can be adjusted according to actual needs.

[0056] Between two adjacent water tanks 1, the bottom shell 16 of one water tank 1 is connected to the heat sink 17 of the other water tank 1, so that each heating component 2 can be in contact with a heat sink 17, ensuring heat dissipation and cooling of each heating component 2, and avoiding overheating of each heating component 2.

[0057] In one embodiment, the bottom shell 16 and the heat dissipation plate 17 of each water tank 1 may be connected by friction welding to ensure the sealing structure of each water tank.

[0058] In a specific embodiment, as shown in Figures 1 to 5, three water tanks 1 may be provided, and the three water tanks 1 are respectively a first water tank 1a, a second water tank 1b, and a third water tank 1c along the preset direction.

After heat exchange, it converges to the water outlet 15 of the heater through the water outlet channel 12 on the first water tank 1a, the water outlet channel 12 on the second water tank 1b and the water outlet channel 12 on the third water tank 1c, and finally flows out from the water outlet 15 of the heater. The first heating component 2a and the second heating component 2b realize heating of the flowing medium in the above-mentioned circulation process.

[0065] In one embodiment, as shown in Figures 4 and 5, a first protrusion 171 is provided on the side of the heat sink 17 of the second water tank 1b facing the first heating component 2a. The provision of the first protrusion 171 allows for more complete contact between the heat sink 17 of the second water tank 1b and the first heating component 2a, thereby improving heat transfer efficiency.

[0066] The heat sink 17 of the third water tank 1c is provided with a second protrusion 172 on the side facing the second heating component 2b. The second protrusion 172 allows for more complete contact between the heat sink 17 of the third water tank 1c and the second heating component 2b, thereby improving heat transfer efficiency.

[0069] At this time, the heat dissipation plates 17 of the three water tanks 1 will be used to dissipate heat for one electronic control component 8 and two heating components 2 respectively.

[0070] In one embodiment, as shown in Figures 2 to 6, in order to reduce the space occupied by the water heater and improve the space occupancy rate, an electrical channel 18 for electrical connection can be set at the edge position of the second water tank 1b and the third water tank 1c to facilitate the electrical connection between the electronic control component 8 and each of the heating components 2.

[0071] At this time, the heat-generating seal 6 can also be used to seal the electrical channel 18 to ensure the stability of electrical connectivity.
