[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following is for reference. Figures 1-5 The heater 1 according to an embodiment of the present invention is described.

[0036] According to the heater 1 of the first aspect embodiment of the present invention, as follows: Figures 1-5 As shown, the heater 1 may include: a first heater body 10, a second heater body 20, and a heating structure 30. An electrical chamber 11 is formed inside the first heater body 10, and an electrical component 111 is installed inside the electrical chamber 11. The second heater body 20 and the first heater body 10 are arranged along a first direction, and the second heater body 20 is fixed to the first heater body 10. The second heater body 20 defines a heat exchange medium flow channel 21. The heating structure 30 is disposed inside the heat exchange medium flow channel 21, and the second heater body 20 has a heat exchange medium inlet 22 and a heat exchange medium outlet 23. The heat exchange medium flow channel 21 connects the heat exchange medium inlet 22 and the heat exchange medium outlet 23.

[0037] It should be noted that in existing heaters, the heat exchange medium flow channel is completely integrated into the shell. The shell also houses electrical components and a complex heat exchange medium flow channel structure, making the shell structure complex. The shell is generally made of die-cast aluminum, which makes it easy to produce defects during the casting process, affecting the structural strength of the shell, the product qualification rate of the shell, the sealing performance of the heat exchange medium flow channel, increasing the risk of heat exchange medium leakage, and affecting the reliability of the heater. In addition, the shell and cover plate shapes of heaters with different power are different, resulting in long development cycles and high development costs.

[0038] Based on this, this application proposes a heater 1, wherein a first heater body 10 is the shell of the heater 1, and a second heater body 20 is the cover plate of the heater 1. The first heater body 10 can be cast from aluminum or aluminum alloy. An electrical chamber 11 can be formed inside the first heater body 10, and electrical components 111 can be installed inside the electrical chamber 11. The electrical components 111 may include PCBA (Printed Circuit Board Assembly), electronic control components, etc. The electrical chamber 11 can be constructed as a sealed space. As an example, such as... Figure 4 As shown, the first heater body 10 may include a body portion 14 and an electrical cover plate 13. The body portion 14 is fixedly connected to the electrical cover plate 13, and the body portion 14 may be bonded to the electrical cover plate 13. The body portion 14 and the electrical cover plate 13 together define an electrical chamber 11.

[0039] The second electric heater body 20 can be arranged along the first heater body 10 in the first direction, and the second electric heater body 20 can be fixedly connected to the first heater body 10. The second electric heater body 20 can be connected to the first heater body 10 by means of bolts, welding, etc. When heater 1 is as Figure 1 When setting the direction, the first direction can be... Figure 1 The second heater body 20 can define a heat exchange medium flow channel 21, which can be spaced apart from the electrical chamber 11. In the prior art, the heat exchange medium flow channel 21 is completely integrated into the first heater body 10. Compared with the prior art, in this application, the heat exchange medium flow channel 21 is located in the second heater body 20, which can improve the structural strength of the second heater body 20, reduce the probability of damage to the second heater body 20 during processing, improve the structural strength and sealing of the heat exchange medium flow channel 21, reduce the risk of heat exchange medium leakage, and help improve the reliability of the heater 1.

[0040] The heat exchange medium can flow within the heat exchange medium channel 21, and the heat exchange medium is generally a liquid such as water. The second heater body 20 may have a heat exchange medium inlet 22 and a heat exchange medium outlet 23. The heat exchange medium channel 21 can connect the heat exchange medium inlet 22 and the heat exchange medium outlet 23. The heat exchange medium can flow into the heat exchange medium channel 21 from the heat exchange medium inlet 22 and flow out of the heat exchange medium channel 21 from the heat exchange medium outlet 23.

[0041] like Figure 4As shown, a heating structure 30 can also be provided within the heat exchange medium flow channel 21, and the heating structure 30 can be immersed in the heat exchange medium. The heating structure 30 can release heat and exchange heat with the heat exchange medium within the heat exchange medium flow channel 21, thus heating the heat exchange medium. As an example, the heating structure 30 can be constructed as a heating tube, which can have a resistance wire. The resistance wire inside the heating tube can generate heat, thereby achieving the effect of heating the heat exchange medium. As another example, the heating structure 30 can be a PTC ceramic. When the heating structure 30 is energized, the current passing through the PTC ceramic element can generate heat, achieving the effect of heating the heat exchange medium. As yet another example, the heating structure 30 can be a heating substrate made of die-cast alloy. The upper surface of the heating substrate is formed by printing and sintering layers from bottom to top in a non-co-fired manner to form an insulating medium layer, a conductive layer, and a protective layer. The heating substrate can generate heat, achieving the effect of heating the heat exchange medium.

[0042] The structure of the heat exchange medium flow channel 21 can be adapted to the shape of the heating structure 30. Heating structures 30 with different power ratings have different shapes, and correspondingly, the shape of the heat exchange medium flow channel 21 also differs. In this application, the heat exchange medium flow channel 21 is located on the second heater body 20. When it is necessary to replace the heating structure 30 with a different power rating, it is also necessary to replace the heat exchange medium flow channel 21 with a different shape. Only the second heater body 20 needs to be replaced; the first heater body 10 does not need to be replaced. That is, only the parameters of the heat exchange medium flow channel 21 on the second heater body 20 need to be adjusted to match the specifications of the heating structure 30. This reduces the difficulty of power iteration for the heater 1, enables rapid updates and iterations of heaters 1 with different power ratings, shortens the development cycle of heaters 1 with different power ratings, and helps save on the development cost of the heater 1. Furthermore, if the heat exchange medium flow channel 21 is damaged and the heater 1 needs repair, only the second heater body 20 needs to be replaced, which reduces the maintenance cost of the heater 1.

[0043] Currently, the air conditioning heat source for new energy vehicles is mainly provided by heater 1. Heater 1 can also provide a heat source for the battery at low temperatures. When the vehicle needs heating (such as battery preheating or cabin heating), the vehicle control system can supply power to heater 1. Heater 1 can provide electrical energy to heating structure 30, which can be converted into heat energy. Heating structure 30 is immersed in heat exchange medium. The heat released by heating structure 30 is transferred to heat exchange medium through heat conduction and convection, which can rapidly increase the temperature of heat exchange medium. The heated heat exchange medium flows out of heat exchange medium channel 21 through heat exchange medium outlet 23 and flows to the target area.

[0044] In this embodiment, the heat exchange medium flow channel 21 is located on the second heater body 20, which reduces the structural complexity and processing difficulty of the first heater body 10, thereby improving the product qualification rate of the first heater body 10. Simultaneously, it enhances the structural strength and sealing of the heat exchange medium flow channel 21 on the second heater body 20, reducing the risk of heat exchange medium leakage and improving the reliability of the heater 1. Furthermore, when developing heaters 1 with different power ratings, only the parameters of the heat exchange medium flow channel 21 on the second heater body 20 and the specifications of the matching heating structure 30 need to be adjusted to achieve rapid updates and iterations of the heater 1. This shortens the development cycle of heaters 1 with different power ratings and reduces their development costs.

[0045] As an example, such as Figure 1 and Figure 2 As shown, the first heater body 10 can be connected to the high-voltage connector 60 and the low-voltage connector 70. Both the high-voltage connector 60 and the low-voltage connector 70 can be installed on the first heater body 10. The high-voltage connector 60 can be connected to the high-voltage wiring harness of the vehicle and can provide power to the heating structure 30. The low-voltage connector 70 can be connected to the low-voltage wiring harness of the vehicle, which can achieve the effect of controlling the heater 1.

[0046] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the second heater body 20 defines a heat exchange medium flow channel 21 that opens toward the first heater body 10, and the first heater body 10 covers the opening end of the heat exchange medium flow channel 21.

[0047] The heat exchange medium flow channel 21 can be located on the side of the second heater body 20 facing the first heater body 10 along the first direction. The second heater body 20 defines the heat exchange medium flow channel 21, which can be open towards the first heater body 10. The first heater body 10 can be fixedly connected to the second heater body 20. The first heater body 10 can cover the open end of the heat exchange medium flow channel 21, thereby improving the sealing performance of the heat exchange medium flow channel 21 and allowing the heat exchange medium to flow within the heat exchange medium flow channel 21. By integrating the heat exchange medium flow channel 21 into the second heater body 20, that is, by setting the complex structure of the heat exchange medium flow channel 21 on the second heater body 20, the structure of the first heater body 10 can be simplified. The first heater body 10 only needs to cover the opening end of the heat exchange medium flow channel 21, which can further reduce the structural complexity of the first heater body 10, further reduce the processing difficulty of the first heater body 10, and further improve the structural strength of the second heater body 20. This can further improve the sealing performance of the heat exchange medium flow channel 21, which is conducive to further improving the reliability of the heater 1.

[0048] In some embodiments of this utility model, such as Figure 4 As shown, the surface of the first heater body 10 facing the second heater body 20 is a first plane 12, which covers the opening end of the heat exchange medium flow channel 21.

[0049] The first plane 12 is located on the side of the first heater body 10 facing the second heater body 20. The first plane 12 can seal the opening end of the heat exchange medium flow channel 21. The first plane 12 has the characteristic of being flat, which can further simplify the structural complexity of the first heater body 10, further reduce the processing difficulty of the first heater body 10, further improve the sealing performance of the heat exchange medium flow channel 21, further reduce the probability of heat exchange medium leakage, and further improve the reliability of the heater 1. The first plane 12 can be constructed as the bottom wall of the heat exchange medium flow channel 21, which can enhance the stability of the heat exchange medium flowing in the heat exchange medium flow channel 21, and is conducive to further improving the heat exchange efficiency between the heat exchange medium and the heating structure 30.

[0050] In some embodiments of this utility model, such as Figures 4-6 As shown, the surface of the second heater body 20 facing the first heater body 10 is a second plane 25, and a sealing structure 40 is provided between the second plane 25 and the first plane 12 to seal the gap between the second plane 25 and the first plane 12.

[0051] The second plane 25 is located on the side of the second heater body 20 facing the first heater body 10. Both the second plane 25 and the first plane 12 are constructed as planes, allowing for a tighter contact and further reducing the possibility of heat exchange medium leakage, thus improving the sealing performance of the heat exchange medium flow channel 21. A sealing structure 40 can be provided between the second plane 25 and the first plane 12, and the sealing structure 40 can be constructed as a ring. When the second heater body 20 is fixed to the first heater body 10, the second plane 25 can abut against the first plane 12, and the sealing structure 40 can be disposed between the second plane 25 and the first plane 12. The sealing structure 40 can seal the gap between the second plane 25 and the first plane 12, thereby further enhancing the sealing performance of the heat exchange medium flow channel 21, further reducing the risk of heat exchange medium leakage, and further improving the reliability of the heater 1.

[0052] As an example, such as Figure 6As shown, the second heater body 20 may have a first mounting hole 81, which extends through the second heater body 20 along its thickness direction (i.e., the first direction) and can be a through hole. The first heater body 10 may have a second mounting hole 82, which extends along the first direction and can be a threaded hole. Bolts may pass through the first mounting hole 81 and mate with the second mounting hole 82, thereby fixing the second heater body 20 to the first heater body 10. There may be multiple first mounting holes 81 and multiple second mounting holes 82. Multiple first mounting holes 81 may correspond one-to-one with multiple second mounting holes 82, and each first mounting hole 81 has a corresponding second mounting hole 82. Bolts may pass through the first mounting hole 81 and mate with the corresponding second mounting hole 82. By providing multiple first mounting holes 81 and second mounting holes 82, the connection strength between the second heater body 20 and the first heater body 10 can be further improved.

[0053] There may be a gap between the second heater body 20 and the first heater body 10 at the bolt connection. The sealing structure 40 can be provided on the side of the connection between the second heater body 20 and the first heater body 10 near the heat exchange medium flow channel 21. The sealing structure 40 can be used to seal the gap between the second heater body 20 and the first heater body 10. The sealing structure 40 can reduce the probability of the heat exchange medium in the heat exchange medium flow channel 21 leaking through the first assembly hole 81 and the second assembly hole 82, and can further improve the reliability of the heater 1.

[0054] The connection between the first plane 12 and the second plane 25 allows for more uniform stress distribution between the first heater body 10 and the second heater body 20, reducing localized stress concentration and improving the structural stability of the heater 1. This enables the heater 1 to better maintain its structural integrity during operation, especially when subjected to pressure and temperature changes of the heat exchange medium, thus extending its service life. Furthermore, the plane facilitates machining, reducing the manufacturing difficulty and cost of the first heater body 10 and the second heater body 20. The second plane 25, which abuts against the first plane 12, facilitates the positioning and installation of the first heater body 10 and the second heater body 20 during assembly, improving assembly efficiency and accuracy, and ultimately enhancing the overall quality of the heater 1.

[0055] In some embodiments of this utility model, such as Figure 4 As shown, at least one of the first heater body 10 and the second heater body 20 has a mounting groove 50, and at least a portion of the sealing structure 40 is mounted in the mounting groove 50.

[0056] The first heater body 10 and the second heater body 20 may each have a mounting groove 50. When the first heater body 10 has a mounting groove 50, the mounting groove 50 may be located on the first plane 12 and may be recessed towards the inside of the first heater body 10. When the second heater body 20 has a mounting groove 50, the mounting groove 50 may be located on the second plane 25 and may be recessed towards the inside of the second heater body 20. This embodiment of the application uses the first heater body 10 having a mounting groove 50 as an example for illustration.

[0057] The sealing structure 40 can be used to seal the gap between the first heater body 10 and the second heater body 20. At least a portion of the sealing structure 40 can be embedded in the mounting groove 50. When the first heater body 10 and the second heater body 20 are fixedly connected, the sealing structure 40 in the mounting groove 50 can be compressed. When compressed, the sealing structure 40 can better fit the first heater body 10 and the second heater body 20. The sealing structure 40 can tightly fill the gap between the first heater body 10 and the second heater body 20, which can keep the sealing structure 40 in a stable position during operation, give full play to the sealing function of the sealing structure 40, and thus form an effective seal, which can further reduce the risk of heat exchange medium leakage.

[0058] The mounting groove 50 provides a defined installation position for the sealing structure 40, facilitating its installation and positioning. This makes the installation process more convenient and accurate, allowing installers to easily place the sealing structure 40 into the mounting groove 50, improving installation efficiency and reducing the risk of seal failure due to improper installation. Furthermore, the mounting groove 50 provides some protection for the sealing structure 40, preventing damage or deformation during installation and removal. During heater 1 operation, the constraint of the mounting groove 50 reduces the probability of displacement or twisting due to external forces, thus extending the service life of the sealing structure 40.

[0059] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the heat exchange medium flow channel 21 may include multiple sub-medium flow channels 211, which are connected in series and any two adjacent sub-medium flow channels 211 are bent and connected. The two sub-medium flow channels 211 located at the ends are respectively connected to the heat exchange medium inlet 22 and the heat exchange medium outlet 23.

[0060] The heat exchange medium flow channel 21 may include multiple sub-medium flow channels 211, which are connected in series and interconnected. Any two adjacent sub-medium flow channels 211 are bent and connected. By setting multiple sub-medium flow channels 211 to bend and connect, the structure of the heat exchange medium flow channel 21 can be made compact, reducing the space occupied by the heat exchange medium flow channel 21. It can also increase the length of the heat exchange medium flow channel 21 within a limited space, increasing the heat exchange area between the heat exchange medium and the heating structure 30, allowing the heat exchange medium to absorb the heat generated by the heating structure 30 more fully, thereby improving the heat exchange efficiency. In addition, appropriate bending angles and shapes can also buffer and regulate fluid pressure, making the flow of the heat exchange medium in the heat exchange medium flow channel 21 more stable. By rationally designing the number, size, and bending angle of the sub-medium flow channels 211, the flow velocity and pressure of the heat exchange medium in the heat exchange medium flow channels 21 can be better controlled, and the resistance of the heat exchange medium flow channels 21 can be reduced to a certain extent, so that the heat exchange medium can flow stably in the heat exchange medium flow channels 21, which is conducive to improving the working efficiency of the heater 1.

[0061] The heat exchange medium flow channel 21 can connect the heat exchange medium inlet 22 and the heat exchange medium outlet 23. Two sub-medium flow channels 211 located at the ends can be connected to the heat exchange medium inlet 22 and the heat exchange medium outlet 23 respectively. This allows the heat exchange medium to enter the heat exchange medium flow channel 21 from the heat exchange medium inlet 22, flow through multiple sequentially connected sub-medium flow channels 211, and then exit from the heat exchange medium outlet 23, thereby significantly increasing the heat exchange area between the heat exchange medium and the heating structure 30. By flowing sequentially through multiple sub-medium flow channels 211, the heat exchange medium has sufficient time and space to exchange heat with the heating structure 30, thus maximizing the absorption or release of heat and effectively improving heat exchange efficiency.

[0062] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the second heater body 20 has a mounting flange 24 formed on its circumferential edge. Fasteners 80 are inserted through the mounting flange 24 and fixed to the first heater body 10, so that the second heater body 20 is fixed to the first heater body 10.

[0063] The second heater body 20 may have a mounting flange 24, which extends circumferentially along the second heater body 20 and is integrally formed with the second heater body 20. The mounting flange 24 can abut against the first plane 12, and the fastener 80 (i.e., the bolt in the above embodiment) can pass through the mounting flange 24 and cooperate with the first heater body 10, thereby fixing the second heater body 20 to the first heater body 10. By providing the mounting flange 24, the contact area between the second heater body 20 and the first heater body 10 can be increased, the connection strength between the second heater body 20 and the first heater body 10 can be improved, and the structural stability of the heater 1 can be improved.

[0064] As an example, the mounting flange 24 can have multiple first mounting holes 81. These first mounting holes 81 can penetrate the mounting flange 24 along its thickness direction (i.e., the first direction) and can be through holes. Along the first direction, the first heater body 10 can have multiple second mounting holes 82 at positions corresponding to the mounting flange 24. These second mounting holes 82 can extend along the first direction and can be threaded holes. Fasteners 80 can pass through the first mounting holes 81 and mate with the second mounting holes 82, thereby further strengthening the connection between the second heater body 20 and the first heater body 10. The multiple first mounting holes 81 can be correspondingly arranged with the multiple second mounting holes 82, with each first mounting hole 81 having a corresponding second mounting hole 82. Fasteners 80 can pass through the first mounting holes 81 and mate with the corresponding second mounting holes 82. By providing multiple first mounting holes 81 and second mounting holes 82, the connection strength between the second heater body 20 and the first heater body 10 can be further improved.

[0065] As an example, the mounting flange 24 and the first heater body 10 are connected by fasteners 80, and there is a gap between the mounting flange 24 and the first heater body 10. Part of the sealing structure 40 can be disposed between the mounting flange 24 and the first heater body 10. The sealing structure 40 can be disposed on the side of the mounting flange 24 near the heat exchange medium flow channel 21. Part of the sealing structure 40 can be used to seal the gap between the mounting flange 24 and the first heater body 10, which can reduce the probability of the heat exchange medium in the heat exchange medium flow channel 21 leaking through the first assembly hole 81 and the second assembly hole 82.

[0066] The second heater body 20 and the first heater body 10 are connected by fasteners 80. During installation, the mounting flange 24 of the second heater body 20 is aligned with the first heater body 10, and then the fasteners 80 are tightened to complete the installation. When disassembly is required for maintenance or repair, the second heater body 20 and the first heater body 10 can be easily separated by unscrewing the fasteners 80. The operation is simple and quick, facilitating daily maintenance and troubleshooting of the equipment.

[0067] In some embodiments of this utility model, the inner wall of the heat exchange medium flow channel 21 is provided with a protruding structure.

[0068] The inner wall of the heat exchange medium flow channel 21 may have a protruding structure, which can be constructed as a finned structure, a spiral structure, etc. The protruding structure can be welded to the second heater body 20, or it can be integrally formed with the second heater body 20. By setting the protruding structure, the flow rate of the heat exchange medium in the heat exchange medium flow channel 21 can be reduced, the heat exchange time between the heating structure 30 and the heat exchange medium can be extended, and the heat exchange effect between the heating structure 30 and the heat exchange medium can be further enhanced, which is conducive to further increasing the temperature of the heat exchange medium when it flows out of the heat exchange medium flow channel 21.

[0069] In some embodiments of this invention, the heat exchange medium inlet 22 and the heat exchange medium outlet 23 are located on the same side of the heater 1.
