[0033] The utility model provides a water heating heater housing. Figure 1-Figure 4 A specific embodiment of a water-heating heater provided by the utility model.

[0034] like Figure 2The utility model embodiment provides a water-heating heater shell 100, including a bottom shell 1 and an upper cover 2, the upper cover 2 is arranged on the bottom shell 1 and a mounting cavity 3 for mounting a heating core is formed therebetween, a first heat exchange flow path and a second heat exchange flow path suitable for exchanging heat with the mounting cavity are formed inside the bottom shell 1 and the upper cover 3 respectively, an inlet and outlet water channel 11 is opened on the bottom shell, the first heat exchange flow path is connected with the inlet and outlet water channel 11, the first heat exchange flow path is connected with the second heat exchange flow path, a first seal 4 and a second seal 5 are arranged between the upper cover 2 and the bottom shell 1, the first seal 4 is arranged between the mounting cavity 3 and the joint where the first heat exchange flow path and the second heat exchange flow path are connected, and the second seal 5 is arranged at the joint where the first heat exchange flow path and the second heat exchange flow path are connected.

[0035] In the utility model, the heat exchange working principle of the water-heating heat exchanger shell 100 is as follows: the coolant flows into the first heat exchange path and the second heat exchange path through the inlet and outlet water channels 11 respectively, and exchanges heat with the installation cavity 3 in the two heat exchange paths respectively to achieve heat exchange of the heating core 201, and the coolant after heat exchange is discharged through the inlet and outlet water channels 11.

[0036] Among them, a first seal 4 is provided on the periphery of the installation cavity, so as to prevent external liquid from splashing into the installation cavity 3, such as rain water, etc. Considering that when the coolant flows from the first heat exchange flow path to the second heat exchange flow path, it will flow through the connecting joint between the two, in order to avoid leakage of the coolant at the connecting joint, which causes the coolant to flow into the installation cavity 3 and cause insulation failure, a second seal 5 is provided at the connecting joint where the first heat exchange flow path is connected to the second heat exchange flow path to prevent internal liquid from flowing out. Considering that the high-temperature and high-pressure coolant will impact the second seal 5 during the heat exchange flow, there is a situation where the second seal 5 fails in part, the utility model arranges the second seal 5 outside the first seal 4, so that the first seal 4 can prevent the cold cutting liquid leaked from the second seal 5 from flowing into the installation cavity while preventing the external liquid from flowing in.

[0037] It should be noted that in the embodiment provided by the utility model, the first heat exchange flow path and the second heat exchange flow path are connected to the water inlet and outlet channels 11 in parallel, and both are synchronously heat exchanged with the heater core through the inner wall surface of the installation cavity 3. Moreover, the specific extension form of the first heat exchange flow path and the second heat exchange flow path is not limited, as long as they can exchange heat with the installation cavity 3, for example, they can be hollow pipes formed in the bottom shell 1 and the upper cover 2.

[0038] Specifically, in some embodiments, the upper cover 2 is detachably covered on the bottom shell 1 by fasteners.

[0039] Specifically, in some embodiments, the bottom shell 1 and / or the upper cover 2 are provided with an overflow groove 6, and one end of the overflow groove 6 is connected to the outside of the bottom shell 1 and / or the upper cover 2. In this way, when the second seal 5 fails, when the high-temperature and high-pressure coolant leaks from the second seal 5, it will directly flow out of the shell through the overflow groove 6 without affecting the first seal 4. The reduction of coolant only affects the heating effect of the vehicle and will not cause the vehicle to break down. The owner can still drive a certain mileage to repair after discovering the problem. The overflow groove 6 cooperates with the first seal 4 and the second seal 5 to work simultaneously to achieve a triple waterproof effect, which greatly improves the waterproof effect and service life of the water heater 200. It can be understood that a plurality of overflow grooves 6 can be provided. For example, in this embodiment, an overflow groove 6 is provided between the first mounting groove 8 and the two second mounting grooves 9.

[0040] Specifically, in some embodiments, one of the upper cover 2 and the bottom shell 1 is provided with a first mounting groove 8 for accommodating the first seal 4; and / or, one of the upper cover 2 and the bottom shell 1 is provided with a second mounting groove 9 for accommodating the second seal 5; the first mounting groove 8 and the second mounting groove 9 provide accommodation space for the first seal 4 and the second seal 5 respectively, ensuring that the seals are completely accommodated therein, avoiding the problem of poor sealing caused by directly fitting on an uneven or concave surface, and the sealing ring can be uniformly compressed in the mounting groove, and can fit more closely on the interface required for sealing, thereby improving the sealing effect. In addition, the mounting groove can also play a fixing role, so that the seal is not easy to move or fall off. It should be noted that the above two schemes of setting the first mounting groove 8 and the second mounting groove 9 can be used selectively or simultaneously, and the sealing and waterproofing effect is better when both are used simultaneously.

[0041] Further, in some embodiments, the first seal 4 protrudes from the first mounting groove 8, the upper cover 2 is disposed on the bottom shell 1 and presses the first seal 4; and / or, the second seal 5 protrudes from the second mounting groove 9, the upper cover 2 is disposed on the bottom shell 1 and presses the second seal 5, so that, by means of pressing, the first seal 4 and the second seal 5 have sufficient compression and can be better filled in the first mounting groove 8 and the second mounting groove 9, which can reduce the influence of the depression or other rough surfaces on the surface around the interface on the seal, thereby providing a more reliable sealing effect, and can also prevent it from loosening or shifting due to vibration, impact or pressure changes during operation, thereby improving the stability of the seal. It should be noted that the above two solutions about the first seal 4 protruding from the first mounting groove 8 being pressed by the upper cover or the bottom shell and the second seal 5 protruding from the second mounting groove 9 being pressed by the upper cover or the bottom shell can be used either or both, and the sealing and waterproofing effect is better when both are used at the same time.

[0042] Furthermore, in some embodiments, the other of the upper cover 2 and the bottom shell 1 is provided with a first ridge corresponding to the first mounting groove 8 for pressing the first seal 4; and / or, the other of the upper cover 2 and the bottom shell 1 is provided with a second ridge corresponding to the second mounting groove 9 for pressing the second seal 5. By pressing the seal in the mounting groove with the ridge, the pressing pressure is increased, thereby further improving the sealing effect and sealing stability. It should be noted that the above two schemes of setting the first ridge and the second ridge can be used either or both, and the sealing and waterproofing effect is better when both are used at the same time.

[0043] In practical applications, the heating core has recesses on both sides. Therefore, in some embodiments, the inner wall of the installation cavity 3 is provided with a convex portion 7 for positioning with the heating core 201. When the heating core 201 is installed in the installation cavity 3, the convex portion 7 will be positioned with the recess of the heating core 201 to play a limiting role, and the convex portion 7 can abut against the recess, which can increase the heat exchange contact area with the heating core 201 and improve the heat exchange efficiency. It should be noted that each of the convex portions is in contact with the first heat exchange flow path or the second heat exchange flow path for heat conduction.

[0044] Specifically, in some embodiments, the inner wall of the installation cavity 3 is provided with a heat-conducting layer to improve the heat conduction efficiency between the heating core 201 and the first heat exchange path and the second heat exchange path. It should be noted that the heat-conducting layer is not specifically limited and can be a heat-conducting material coated on the inner wall of the installation cavity, such as thermally conductive silicone or thermally conductive grease with thermally conductive insulation properties.

[0045] Specifically, in some embodiments, the water inlet and outlet channel 11 includes a water inlet channel 111 and a water outlet channel 112, the first heat exchange flow path is respectively connected to the water inlet channel 111 and the water outlet channel 112, the first heat exchange flow path includes a first water inlet interface 12 and a first water outlet interface 13, and the second heat exchange flow path includes a second water inlet interface 21 connected to the first water inlet interface 12 and a second water outlet interface 22 connected to the first water outlet interface 13. In this way, by separately arranging the water inlet channel 111 and the water outlet channel 112, mutual interference of water flows between the two is avoided, the smooth flow of water flows in their respective channels is ensured, and the delivery efficiency and heat exchange efficiency of the coolant are improved.

[0046] It should be noted that the second sealing member is not specifically limited and may be a sealing strip or a sealing ring, etc. In some embodiments, the second sealing member 5 includes a water inlet sealing ring 51 provided between the first water inlet docking port 12 and the second water inlet docking port 21 and a water outlet sealing ring 52 provided between the first water outlet docking port 13 and the second water outlet docking port 22. Since the water inlet sealing ring 51 and the water outlet sealing ring 52 need to withstand the impact of high-temperature liquid, preferably, the water inlet sealing ring 51 and the water outlet sealing ring 52 are sealing rings made of EPDM rubber.

[0047] The first sealing member is also not specifically limited, and can be a sealing strip or a sealing ring, etc. In some embodiments, the first sealing member 4 includes a core sealing ring 41, and the core sealing ring 41 is arranged outside the installation cavity to completely isolate the external rainwater and the coolant leaked at the joint, greatly improving the waterproof effect. Preferably, the core sealing ring 41 is a sealing ring made of silicone or EPDM rubber.

[0048] The utility model also provides a water heater 200, comprising a heating core 201, a power supply assembly and the water heater housing 100, wherein the heating core 201 is installed in the installation cavity 3, the power supply assembly is installed in the water heater housing 100, and the heating core 201 is electrically connected to the power supply assembly. The first seal 4, the second seal 5 and the overflow groove 6 provided on the water heater housing 100 simultaneously play a triple waterproof effect, greatly improving the sealing and waterproof effect and service life of the water heater 200.

[0049] The utility model also provides a vehicle, comprising the water heater 200 mentioned above.

[0050] It should be noted that the water-heating heater 200 provided by the present invention can be applied to the field of water-heating heaters for vehicles, but is not limited to the field of water-heating heaters for vehicles.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
