Description

Technical Field

[0001] This utility model relates to a vehicle heater, and more particularly to a vehicle heater with optimized heat dissipation. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] In a vehicle's thermal management system, a heater is typically installed. It works in conjunction with the refrigerant in the thermal management system to control the temperature of the fluid, thereby managing the temperature of the vehicle's air conditioning system, battery cooling system, motor cooling system, and so on.

[0004] In some existing vehicle thermal management systems, considering the need for integration, the heater is usually directly mounted on the control board. However, the PCB substrate of a typical control board can withstand temperatures around 150 degrees Celsius, and the base temperature is best controlled below 120 degrees Celsius. In reality, the temperature of the heater during operation often reaches 250 degrees Celsius or even higher. This necessitates separating the controller and the heater through a partition in the existing structure. However, the partition structure requires the use of new adapter plates, bolts, etc. for fixation, which significantly increases the complexity of the installation process.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a vehicle heater with optimized heat dissipation. By setting connected heat dissipation fins on the outside of the cover, the heater inside the cover can be directly cooled, reducing the heat radiation from the heater to the controller side. Therefore, it can replace the complex and costly partition structure.

[0007] To achieve the above objectives, this utility model discloses a heat-optimized vehicle heater, wherein a controller mounted on the compressor is located on the side opposite to the compressor, and the heat-optimized vehicle heater includes: A box cover, which is mounted on the controller, has a slot on the side of the box cover facing the controller; A heating element is installed in the slot, with its inlet end connected to a water inlet pipe outside the cover and its outlet end connected to a water outlet pipe outside the cover. The heat dissipation fins are installed on the side of the cover away from the controller; the cover and the heat dissipation fins are integrally formed. A partition is provided in the slot of the box cover. The partition extends along the direction from the controller to the box cover. The heating tube includes a first tube segment and a second tube segment. The partition is located between the first tube segment and the second tube segment of the heating tube. The partition is integrally formed with the box cover.

[0008] As a further description of the above technical solution, the heat dissipation fins are configured to radiate outwards from the center point of the lid.

[0009] As a further description of the above technical solution, the heat dissipation fins extend along the direction from the controller to the cover.

[0010] As a further description of the above technical solution, the heating tube is configured as a U-shaped tube, and the inlet end and outlet end of the heating tube are connected to the same plane on the box cover.

[0011] As a further description of the above technical solution, heat dissipation fins are installed in the heating tube.

[0012] As a further description of the above technical solution, the cross-section of the heat dissipation fins is configured to radiate outwards from the center point of the heating pipe cross-section.

[0013] As a further description of the above technical solution, the projection surface of the box cover is the same as that of the controller.

[0014] Based on the above technical solution, the beneficial effects of this utility model are as follows: This invention relates to a vehicle-mounted heater with optimized heat dissipation. By incorporating connected heat dissipation fins on the outer side of the housing cover, the heater inside the housing can be directly cooled, reducing heat radiation from the heater to the controller side. Therefore, it can replace the complex and costly partition structure. Specifically, during heating element operation, heat dissipation can be aided by heat dissipation fins on the side opposite the controller, indirectly reducing the heat radiation intensity on the controller side. Compared to existing partition solutions, the heat dissipation fins are directly located on the outer side of the housing cover, allowing for an integrated construction or separate installation during housing setup. This simplified structure significantly reduces manufacturing costs.

[0018] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments.

Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustration only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.

[0020] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. 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.

[0021] Please see Figure 1-2 This embodiment describes a heat-optimized vehicle heater, in which a controller 200 mounted on the compressor 100 is located on the side opposite to the compressor 100. The heat-optimized vehicle heater comprises: The cover 1 is mounted on the controller 200, and the cover 1 has a slot 11 on the side facing the controller 200; Heating tube 2 is installed in slot 11. The inlet end of heating tube 2 is connected to the water inlet pipe 3 outside the box cover 1, and the outlet end of heating tube 2 is connected to the water outlet pipe 4 outside the box cover 1. Heat dissipation fin 5 is installed on the side of the cover 1 away from the controller 200.

[0022] For the above structure, during installation, a cover 1 with heat dissipation fins 5 can be prefabricated. After the heating tube 2 is installed in the slot 11 of the cover 1, the cover 1 is directly snapped onto the side of the controller 200 away from the compressor 100 and fixedly connected by fasteners. This eliminates the step of installing a partition between the cover 1 and the controller 200.

[0023] In practical use, fluid is introduced into the heating tube 2 through the inlet pipe 3. The heating tube 2 then heats itself, either by increasing the temperature of the thick film covering its outer wall, thus heating the fluid within the tube. This continuous heating continues until the fluid flows out of the cover 1 through the outlet pipe 4 and into a designated heat exchange unit, completing the heat exchange function. This cycle repeats. During the heating process, the heating tube 2 also continuously releases heat. Specifically, the controller 200, located near the bottom of the heating tube 2, contains a PLC board that continuously receives heat radiation from the heating tube 2. In response, the heat radiation from the heating tube 2 is transferred to the top of the cover 1, and the top of the cover 1 is provided with protruding heat dissipation ribs 5. The heat dissipation ribs 5 increase the contact area between the cover 1 and the air. Therefore, the combination of the cover 1 and the heat dissipation ribs 5 in this application undertakes more heat dissipation and has stronger heat dissipation capacity. Thus, some of the heat radiation that originally needed to be transferred to the controller 200 can be released through the cover 1 and the heat dissipation ribs 5.

[0024] Based on the above structure, by setting connected heat dissipation ribs 5 on the outside of the cover 1, the heater inside the cover 1 can be directly cooled by the heat dissipation ribs 5, reducing the heat radiation from the heater to the controller 200 side. Therefore, it can replace the complex and costly partition 6 structure. Specifically, in the use of the heating tube 2, the heat dissipation ribs 5 on the side away from the controller 200 can assist in heat dissipation, thus indirectly reducing the heat radiation intensity on the controller 200 side. Compared with the existing partition 6 solution, the heat dissipation ribs 5 are directly set on the outside of the cover 1. When setting the cover 1, an integrated structure or additional installation can be considered, which simplifies the structure and significantly reduces the manufacturing cost.

[0025] In this utility model, the cover 1 and the heat dissipation rib 5 are integrally formed. That is to say, in the forming stage, the cover 1 and the heat dissipation rib 5 are integrally formed, which reduces the step of combining the cover 1 and the heat dissipation rib 5 in the installation stage, significantly improving the installation efficiency. Moreover, in a mass production environment, the cost can be lowered, and there is no need to use additional bolts to insert the cover 1. The structural strength of the cover 1 can be higher.

[0026] Please see Figure 2 The heat dissipation ribs 5 are arranged radially from the center point of the cover 1. Furthermore, the heat dissipation ribs 5 extend along the direction from the controller 200 to the cover 1. The radial heat dissipation ribs 5 possess better structural strength, and since they extend from the center near the heating tube 2, the heat dissipation ribs 5 have the largest contact area with air near the center of the heating tube 2, resulting in the strongest heat dissipation capacity. Combined with the most uniform temperature range at the center of the heating tube 2, this makes the heat dissipation from the heat dissipation ribs 5 to the cover 1 more uniform and stable. Simultaneously, the radial heat dissipation ribs 5 do not need to consider the irregular shape of the cover 1; finding only the center point of the cover 1 is sufficient to meet most of the uniform heat dissipation requirements. The aforementioned center point refers to the geometric center point of the projected surface of the cover 1. For example, in a cover 1 with an approximately rectangular projected surface, its center point is the intersection of the two diagonals of the rectangle.

[0027] Furthermore, the heating tube 2 is configured as a U-shaped tube, with its inlet and outlet ends connected to the same plane on the cover 1. The U-shaped tube structure of the heating tube 2 makes the inlet and outlet ends connected to the same plane, so the water inlet pipe 3 and the water outlet pipe 4 can also be on the same plane, which facilitates the integration and installation of the structure and makes it easier for later maintenance. The U-shaped tube can make full use of the area of ​​the slot 11.

[0028] Based on the aforementioned U-shaped structure, a partition 6 is provided in the slot 11 of the cover 1. The partition 6 extends along the direction from the controller 200 to the cover 1, and is positioned in the middle of the U-shaped tube to isolate the two sections of the U-shaped tube. In other words, the U-shaped tube can be divided into a first section, a second section, and a connecting section in the middle. Figure 3The bending section shown is used for heating, while the first and second sections of the U-shaped tube with longer lengths are mainly used for heating. In this application, the first and second sections of the U-shaped tube are separated by a partition 6, which makes the heat dissipation effect more uniform. At the same time, the partition 6 itself can act as a heat carrier, making full use of the U-shaped structure to achieve heat conduction in the horizontal direction. The heat of the first and second sections of the U-shaped tube is directly conducted to the two side walls of the partition 6 in the horizontal direction, and then transferred from the partition 6 to the heat dissipation fins 5 outside the cover 1, thus achieving a better heat dissipation effect.

[0029] Of course, the first and second pipe sections mentioned above can also be set as other types of parallel pipes besides U-shaped pipes, with the partition 6 clamped in the middle to play an auxiliary role in heat dissipation.

[0030] Specifically, the partition 6 is integrated with the cover 1, which is also for ease of installation. The partition 6 itself can enhance the structural strength of the cover 1, and the partition 6 can also play a role in positioning the heating tube 2 during the installation stage.

[0031] In another embodiment, heat dissipation fins 21 are installed in the heating tube 2. The cross-section of the heat dissipation fins 21 is set to radiate outward from the center point of the cross-section of the heating tube 2. The main function of the heat dissipation fins 21 is to increase the heat-receiving area of ​​the fluid inside the heating tube 2. With the help of the heat dissipation fins 21 in the heating tube 2, the fluid can absorb more heat, thus indirectly preventing more heat from radiating to the outside and reducing the heat radiated to the controller 200.

[0032] The aforementioned heat dissipation fins 21 and heat dissipation ribs 5, one inside and one outside, form a two-layer heat dissipation space, thus minimizing the ineffective heat radiation from the heating tube 2 to the outside.

[0033] In another embodiment, the projection surface of the cover 1 is the same as that of the controller 200; please refer to [link / reference]. Figure 1 , 2 The cover 1 can be completely matched with the controller 200 on one side, with a higher degree of integration. In essence, the projection surface coverage of the heat dissipation fin 5 is also matched with the controller 200, which can maximize the area utilization of the heat dissipation fin 5.

Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0035] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0036] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
