[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 6 This utility model provides a dual-channel PTC water heater for vehicles, comprising a first heater 1 and a second heater 2. The second heater 2 is disposed on one side of the first heater 1. The front ends of both the first heater 1 and the second heater 2 are connected to water inlet pipes 3, and the rear ends of both the first heater 1 and the second heater 2 are connected to water outlet pipes 4. Controllers 5 are fixedly installed on the upper surfaces of both the first heater 1 and the second heater 2, and heating blocks 6 are fixedly installed inside both the first heater 1 and the second heater 2.

[0031] To connect heater 1 and heater 2, a fixing block 7 is fixedly installed on the side wall of heater 1 near heater 2, and a positioning block 8 and a locking block 9 are fixedly installed on the side wall of heater 2 near heater 1. The two ends of the fixing block 7 are slidably connected to the side walls of the two positioning blocks 8. The side wall of the fixing block 7 is provided with a locking groove 10. Both the locking block 9 and the locking groove 10 are T-shaped. The locking block 9 is slidably connected to the inner wall of the locking groove 10. An installation frame 11 is fitted on the outer surface of heater 1 and heater 2.

[0032] To simultaneously install heater 1 and heater 2, sliders 12 are fixedly installed on the opposite sidewalls of both heaters 1 and 2. Slide grooves are provided on the inner walls of both sides of the mounting frame 11, and the two sliders 12 are slidably connected to the inner walls of their respective slide grooves. Two grooves 13 are provided at the front and rear ends of the mounting frame 11, and two inlet pipes 3 and two outlet pipes 4 are slidably connected to the inner walls of their respective grooves 13. Multiple fixing bolts 14 are threaded onto the outer surface of the mounting frame 11, penetrating the outer wall of the mounting frame 11. Multiple fixing holes are provided on the outer surfaces of both heaters 1 and 2, and the multiple fixing bolts 14 are inserted into their respective fixing holes. Mounting plates 15 are fixedly installed on both sides of the mounting frame 11.

[0033] By setting up heater 1, heater 2, inlet pipe 3, outlet pipe 4, controller 5, heating block 6, fixing block 7, positioning block 8, locking block 9, locking groove 10, mounting frame 11, slider 12, groove 13, fixing bolt 14, and mounting plate 15, the function of uniformly installing heater 1 and heater 2 is realized. This improves the installation method of two PTC water heaters in the existing technology, allowing heater 1 and heater 2 to be connected and installed uniformly, thereby reducing the space occupied by PTC water heaters inside electric vehicles. At the same time, it eliminates the need for repeated installation of PTC water heaters, saving time and effort for staff.

[0034] The upper surface of the mounting frame 11 is provided with a protective component, which includes a fixed frame 16 and a telescopic rod 17. The fixed frame 16 is set on the upper surface of the mounting frame 11, and the telescopic rod 17 is fixedly installed on the upper surface of the fixed frame 16. A protective plate 18 is fixedly installed at the top of the telescopic rod 17. A spring 19 is sleeved on the outer surface of the telescopic rod 17. The top of the spring 19 is fixedly connected to the protective plate 18, and the bottom of the spring 19 is fixedly connected to the fixed frame 16. Two connecting blocks 20 are fixedly installed on the lower surfaces of both ends of the fixed frame 16. Two connecting grooves 21 are opened on both side walls of the mounting frame 11. Connecting bolts 22 are threadedly connected to the side walls of the connecting blocks 20. The four connecting blocks 20 are slidably connected to the inner walls of the corresponding connecting grooves 21. The connecting bolts 22 penetrate the connecting blocks 20 and are inserted into the inner walls of the connecting grooves 21.

[0035] By setting up a fixed frame 16, a telescopic rod 17, a protective plate 18, a spring 19, a connecting block 20, a connecting groove 21, and a connecting bolt 22, the function of protecting the top of heater 1 and heater 2 is realized. By setting up a protective plate 18 and a spring 19, the top of heater 1 and heater 2 can be buffered and protected, thereby protecting the controller 5 on heater 1 and heater 2, preventing the controller 5 from being damaged by external forces, ensuring the normal use of heater 1 and heater 2, and improving the safety of PTC water heaters.

[0036] Working principle: When installing two PTC water heaters, first place heater 1 and heater 2 into the mounting frame 11 respectively, so that the sliders 12 on heater 1 and heater 2 slide into the two sliding grooves respectively, the two inlet pipes 3 and the two outlet pipes 4 slide into the corresponding grooves 13 respectively, and at the same time, the fixing block 7 slides into the two positioning blocks 8, and the locking block 9 slides into the locking groove 10, so that heater 1 and heater 2 are connected. After heater 1 and heater 2 slide into the mounting frame 11, screw multiple fixing bolts 14 onto the outer surface of the mounting frame 11 to fix heater 1 and heater 2.

[0037] Next, move the fixing frame 16 and the protective plate 18 close to the mounting frame 11, so that the fixing frame 16 is above the mounting frame 11, align the connecting block 20 with the connecting groove 21, move the fixing frame 16 so that the fixing frame 16 moves closer to the mounting frame 11, and slide the connecting block 20 into the interior of the connecting groove 21. When the fixing frame 16 contacts the upper surface of the mounting frame 11, tighten the connecting bolt 22 to fix the fixing frame 16 through the connecting block 20.

[0038] After the fixing frame 16 is fixed, the mounting frame 11 drives the first heater 1 and the second heater 2 to be fixedly installed into the interior of the electric vehicle through the mounting plate 15, thus completing the installation of the PTC heater. At this time, when the PTC heater receives a force from above, the protective plate 18 moves down, the telescopic rod 17 shortens, and the spring 19 is compressed and deformed. During the restoration process, the spring 19 pushes the protective plate 18 upward to buffer the force from above, thereby protecting the first heater 1 and the second heater 2.

[0039] When heater 1 and heater 2 are in use, their interiors are filled with cooling water. Two controllers 5 control two heating blocks 6 to heat the cooling water inside heater 1 and heater 2 respectively. The cooling water exits heater 1 and heater 2 through outlet pipe 4 and begins circulating within the electric vehicle. After circulation is complete, the circulated cooling water re-enters heater 1 and heater 2 through inlet pipe 3. Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
