These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.
[0036] Please see Figure 1-3 In this embodiment, a sealed-optimized vehicle heater is provided, wherein a controller 200 mounted on the compressor 100 is located on the side opposite to the compressor 100, and the sealed-optimized vehicle heater includes:
[0037] The cover 1 is mounted on the controller 200, and the side of the cover 1 facing the controller 200 includes a slot 11;
[0038] Heating tube 2 is installed in slot 11. Heating tube 2 includes a first tube body 21, a second tube body 22 and a connecting tube 23. The first end of the first tube body 21 is connected to the water inlet pipe 24 that passes through the cover 1. The first end of the second tube body 22 is connected to the water outlet pipe 25 that passes through the cover 1. The second ends of the first tube body 21 and the second tube body 22 are connected by the connecting tube.
[0039] The first limiting plate 3 is sleeved on the first end of the first tube body 21 and the second tube body 22, and forms a first isolation cavity 31 with the first end of the slot 11.
[0040] The second limiting plate 4 is sleeved at the connection between the second end of the first pipe body 21 and the second pipe body 22 and the connecting pipe 23, and forms a second isolation cavity 41 with the second end of the slot 11.
[0041] Among them, the first isolation chamber 31 and the second isolation chamber 41 are filled with glue for sealing.
[0042] In this invention, during installation, the first limiting plate 3 and the second limiting plate 4 can be pre-assembled with the first tube body 21, the second tube body 22, and the adapter tube 23 of the heating tube 2. The first limiting plate 3 is fitted onto the same end of the first tube body 21 and the second tube body 22, and the second limiting plate 4 is fitted between the adapter tube 23 and the first tube body 21 and the second tube body 22. Then, the installed heating tube 2 is installed in the slot 11 of the cover 1, so that the first limiting plate 3 isolates the slot 11 into a corresponding first isolation cavity 31, and the second limiting plate 4 isolates the second isolation cavity 41. Glue is then applied to fill the first isolation cavity 31 and the second isolation cavity 41 with sealant. Finally, the cover 1 is sequentially pressed onto the controller 200, which is then mounted on the compressor, and the inlet pipe 24 and the outlet pipe 25 are connected.
[0043] In the above solution, the sealing performance of the product is significantly improved by separating the two ends of the heating tube 2 into two isolation cavities through limiting plates and then applying adhesive. Specifically, in this utility model, the first isolation cavity 31 is separated on one side of the first end of the slot 11 by the first limiting plate 3. The first isolation cavity 31 is used to improve the sealing performance on the inlet / outlet side. The second isolation cavity 41 is separated on one side of the second end of the slot 11 by the second limiting plate 4. The second isolation cavity 41 is used to improve the sealing performance on the side of the adapter pipe 23, preventing leakage at the connection between the adapter pipe 23 and the first pipe body 21 and the second pipe body 22. It is easy to install and has a good sealing effect.
[0044] Specifically, the first isolation chamber 31 effectively blocks the leakage of fluid in the heating tube 2 towards the first end of the slot 11, and the second isolation chamber 41 blocks the leakage of fluid in the heating tube 2 towards the second end of the slot 11. The position between the two ends of the slot 11 can form a good sealing effect through the integrated cover 1 itself.
[0045] Furthermore, the first end of the slot 11 includes a protruding first limiting part 12, which is used to abut against one side of the second end of the first limiting plate 3. Through the first limiting part 12, the first limiting plate 3 can be clamped and positioned, so as to prevent the first limiting plate 3 from moving during glue pouring, avoid the formation of air bubbles, and improve the sealing effect of the first isolation cavity 31.
[0046] Similarly, the second end of the slot 11 includes a protruding second limiting part 13, which abuts against one side of the first end of the second limiting plate 4. Its purpose is also to lock and position the second limiting plate 4, preventing movement of the second limiting plate 4 during glue application, avoiding air bubbles, and improving the sealing effect of the second isolation cavity 41.
[0047] It is worth noting that the first limiting part 12 is used to abut against one side of the second end of the first limiting plate 3, while the second limiting part 13 is used to abut against one side of the first end of the second limiting plate 4. Therefore, by simultaneously tightening the first limiting plate 3 and the second limiting plate 4, the heating tube 2 can be positioned in two directions, thus preventing displacement of the heating tube 2.
[0048] Furthermore, the slot 11 includes a mounting post 14, in which a baffle 15 is installed. At least a portion of the baffle 15 is used to abut against one side of the second end of the first limiting plate 3. The mounting post 14 is positioned between the first tube 21 and the second tube 22, and the baffle 15 is used to abut against the middle of the first limiting plate 3. The main function of the baffle 15 is similar to that of the first limiting part 12, which is to clamp and position the first limiting plate 3. In fact, in one embodiment, the baffle 15 and the first limiting part 12 abut against the first limiting plate 3 from both sides, which has a better positioning effect on the first limiting plate 3.
[0049] Specifically, the mounting post 14 is positioned between the first tube 21 and the second tube 22, and the baffle 15 abuts against the center of the first limiting plate 3. The mounting post 14 includes a screw hole, and the baffle 15 is fixed to the screw hole by a bolt 16 passing through the baffle 15. During installation, simply place the baffle 15 in the screw hole and tighten the bolt 16 to fix the baffle 15. The baffle 15 is centrally positioned and abuts against the center, which allows for a more uniform contact force and prevents deformation or displacement of the first limiting plate 3.
[0050] In another embodiment, such as Figure 2 As shown in the cross-sectional diagram, the inlet pipe 24 is inserted into the first end of the first pipe body 21, and the inlet pipe 24 and the first pipe body 21 are sealed by the first sealing ring 241; the outlet pipe 25 is inserted into the first end of the second pipe body 22, and the outlet pipe 25 and the second pipe body 22 are sealed by the second sealing ring 251. The first sealing ring 241 and the second sealing ring 251 can provide a good primary sealing effect at the pipe body opening connection, and are convenient to install and assemble.
[0051] Furthermore, the inlet conduit 24 includes a first flange 243, one side of the second end of the first flange 243 abutting against one side of the first end of the cover 1, and the second side of the first flange 243 and the first side of the cover 1 are sealed by a third sealing ring 242; the outlet conduit 25 includes a second flange 253, one side of the second flange 253 abutting against one side of the first end of the cover 1, and the second side of the second flange 253 and the first side of the cover 1 are sealed by a fourth sealing ring 252. The first flange 243 clamps the third sealing ring 242 between the cover 1, forming a two-stage seal for the connection between the first pipe body 21 and the inlet conduit 24. With the cooperation of the first sealing ring 241 in the first stage of sealing, the two-stage seal significantly improves the sealing performance of the connecting pipe to the fluid. The fourth sealing ring 252 and the second flange 253 are set in the same way.
