Description

Technical Field

[0001] This utility model relates to the field of heaters, and more specifically, to a heater housing and an MCH heater. Background Technology

[0002] Currently, electric vehicles are developing rapidly, and the driving range of electric vehicles is an extremely important indicator for evaluating them. Especially when the vehicle is in a low-temperature environment, it is necessary to heat the battery and passenger compartment. In existing related technologies, most vehicle thermal management systems use PTC heaters for heating. For example, the PTC heater is attached to one side of the water chamber with thermally conductive silicone to heat the liquid in the water chamber, and heat is transferred by exchanging heat between the liquid and the components to be heated.

[0003] The inventors discovered during their research that the heater housings of existing technologies have at least the following drawbacks:

[0004] The core components of the heater assembly are the heater core and the controller assembly. Both the heater core and the controller assembly have housings. The housings of the heater core and the controller assembly are manufactured independently and then assembled together. This requires two separate molds for the two housings, increasing the manufacturing cost. In addition, the process of manufacturing the two housings separately and then assembling them is cumbersome and has low processing efficiency. Utility Model Content

[0005] The purpose of this invention includes, for example, providing a heater housing and an MCH heater that can reduce manufacturing costs, simplify processes, and improve processing efficiency.

[0006] The embodiments of this utility model can be implemented as follows:

[0007] In a first aspect, this utility model provides a heater housing, comprising:

[0008] The heating core housing and the controller housing are integrally formed, and the heating core housing and the controller housing cooperate to define a first positioning chamber and a second positioning chamber that are independent of each other; the first positioning chamber has a first opening, and the second positioning chamber has a second opening, and the first opening and the second opening are located on opposite sides of the heater housing;

[0009] The first positioning chamber is used to assemble the heating core assembly, and the second positioning chamber is used to assemble the controller assembly.

[0010] In an optional embodiment, a reinforcing rib structure is provided on the inner circumferential surface of the heating core shell that forms the first positioning chamber.

[0011] In an optional embodiment, a snap-fit ​​portion is provided on the outer peripheral surface of the heating core housing.

[0012] In an optional embodiment, the snap-fit ​​portion is configured as a snap-fit ​​groove or a snap-fit ​​protrusion.

[0014] In an optional embodiment, the heater housing further includes a top cover, which is mounted on the heating core housing and closes the first opening; the top cover engages with the snap-fit ​​portion.

[0015] In an alternative embodiment, the heater housing further includes a base that is mounted on the controller housing and closes the second opening.

[0016] In an optional embodiment, the base is welded, bonded, or heat-sealed to the controller housing.

[0017] In an optional embodiment, the controller housing has an annular slot surrounding the second opening on the end face corresponding to the second opening, and the four edges of the base are inserted into the annular slot.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] In existing technologies, heaters, such as PTC heaters or MCH heaters, generally consist of two core components: a heating core assembly and a controller assembly. Both have independent housings. During manufacturing, two sets of molds need to be designed to process the two housings separately, resulting in a large number of molds and high costs. Moreover, the heater assembly requires assembling the two housings together, which is a cumbersome process with low manufacturing efficiency.

[0036] In view of this, the designers have provided a heater housing that can reduce the number of molds, lower manufacturing costs, simplify processes, and improve processing efficiency.

[0037] Please refer to Figure 1 and Figure 2 This embodiment provides a heater housing, which includes an integrally formed heating core housing 100 and a controller housing 200. The heating core housing 100 and the controller housing 200 cooperate to define mutually independent first positioning chambers and second positioning chambers 400. The first positioning chamber 300 has a first opening 310, and the second positioning chamber 400 has a second opening 410. The first opening 310 and the second opening 410 are located on opposite sides of the heater housing. The first positioning chamber is used to assemble the heating core assembly, and the second positioning chamber is used to assemble the controller assembly.

[0038] As described above, the heater housing provided in this embodiment has at least the following advantages:

[0039] By designing the heating core housing 100 and the controller housing 200 as a single integrated structure, i.e., molding them as a single piece, only one set of molds needs to be developed during manufacturing. Compared to existing technologies that require two sets of molds, this reduces the number of molds and lowers manufacturing costs. Furthermore, the integrated molding of the heating core housing 100 and the controller housing 200 eliminates the need for assembly, simplifying the manufacturing process and improving manufacturing efficiency.

[0040] The following embodiments illustrate the details of the heater housing of this application by way of example.

[0041] Please refer to Figures 1-4 In this embodiment, optionally, the heater housing includes a heating core outer shell 100, a controller housing 200, a top cover 600, and a base 700. The heater housing and the controller housing 200 are configured as an integral structure, that is, the heater housing and the controller housing 200 can be integrally molded by injection molding or other methods. The top cover 600 is installed on the heating core outer shell 100, and the base 700 is installed on the controller housing 200.

[0042] Please refer to Figure 1 and Figure 2 Specifically, after the heating core housing 100 and the controller housing 200 are integrally formed, they cooperate to define mutually independent first positioning chambers and second positioning chambers 400. A partition 500 is provided between the first positioning chamber 300 and the second positioning chamber 400, which are located on both sides of the partition 500. The partition 500 is a shared structure of the heating core housing 100 and the controller housing 200, and the partition 500, the heating core housing 100, and the controller housing 200 are integrally formed. At the same time, the side of the first positioning chamber 300 away from the partition 500 is set as a first opening 310. After the top cover 600 is connected to the heating core housing 100, the first opening 310 is closed, thereby protecting the heating core assembly located in the first positioning chamber 300. The side of the second positioning chamber 400 away from the partition 500 is provided as a second opening 410. The first opening 310 and the second opening 410 are located on opposite sides of the heater housing. After the base 700 is connected to the controller housing 200, the second opening 410 is closed, thereby effectively protecting the controller assembly located in the second positioning chamber 400.

[0043] It should be understood that, in order to facilitate the electrical connection between the heating core assembly and the controller assembly, a through hole can be provided on the partition 500 for the pins of the heating core assembly to connect with the controller assembly. A sealing part can be provided at the through hole to improve the sealing performance of the through hole, so that the liquid leaking in the first positioning chamber 300 is not easy to enter the second positioning chamber 400 where the controller assembly is located through the through hole.

[0044] Please refer to Figure 1 Optionally, to improve the structural strength of the heating core shell 100, a reinforcing rib structure 110 is provided on the inner circumferential surface of the heating core shell 100 that forms the first positioning chamber. The reinforcing rib structure 110 can be a raised rib, and there can be multiple raised ribs, which are spaced apart in the circumferential direction on the inner circumferential surface. The number of raised ribs is selected as needed to ensure that the location of the first opening 310 of the heating core shell 100 has sufficient strength.

[0045] Optionally, a snap-fit ​​portion 120 and an annular groove 130 are provided on the outer peripheral surface of the heating core housing 100. It should be understood that the snap-fit ​​portion 120 can be configured as a snap-fit ​​groove or a snap-fit ​​protrusion. For example, in this embodiment, the snap-fit ​​portion 120 is configured as a snap-fit ​​groove for explanation. There can be multiple snap-fit ​​portions 120, which can be arranged at intervals in the circumferential direction of the outer peripheral surface. Meanwhile, the annular groove 130 is designed around the heating core housing 100, and the annular groove 130 has a gap from the first opening 310, so that a portion of the outer peripheral surface of the heating core housing 100 protrudes outward relative to the annular groove 130. All snap-fit ​​portions 120 are located between the first opening 310 and the annular groove 130, with one end of each snap-fit ​​portion 120 having a gap from the end face of the first opening 310, and the other end of each snap-fit ​​portion 120 extending to and communicating with the annular groove 130.

[0046] With this design, when assembling the top cover 600 with the heating core housing 100, the top cover 600 covers one end of the first opening 310 of the heating core housing 100, and the top cover 600 covers all the snap-fit ​​parts 120 around its perimeter. Then, force is applied to the perimeter of the top cover 600, causing it to deform towards the snap-fit ​​part 120, so that the top cover 600 can be snapped into the snap-fit ​​part 120. Due to the structural design of the snap-fit ​​part 120 and the annular groove 130, the perimeter of the top cover 600 is easy to deform and easy to snap into the snap-fit ​​part 120, making assembly convenient and flexible.

[0047] It should be understood that, in order to improve sealing, a sealing ring can be provided between the end face where the top cover 600 and the first opening 310 are located.

[0048] In this embodiment, optionally, the base 700 can be connected to the controller housing 200 by welding, bonding or heat sealing.

[0049] Please refer to Figure 2Optionally, the controller housing 200 is provided with an annular slot 210 around the second opening 410 on the end face corresponding to the second opening 410. The four edges of the base 700 are inserted into the annular slot 210. The base 700 can be bonded to the controller housing 200 by filling the annular slot 210 with glue, or by heating the controller housing 200 to deform it and then heat-sealing it with the base 700.

[0050] To improve the bonding strength between the controller housing 200 and the base 700, a concave-convex part 710 can be provided on the edge of the base 700. The concave-convex part 710 is located in the annular slot 210. Whether it is glued or heat-sealed, an interlocking structure can be formed at the bonding position between the controller housing 200 and the base 700, resulting in a firm and reliable bonding.

[0051] It should be understood that the base 700 can be made of metal plate or plastic plate, etc.

[0052] The heater housing, heating core outer shell 100, and controller housing 200 provided in this embodiment are designed as an integrated structure, requiring only one set of molds to be developed, resulting in low manufacturing costs. Furthermore, it eliminates the need for separate processing and assembly of the two components, simplifying the processing steps and improving efficiency.

[0053] This embodiment also provides an MCH heater, which includes the heater housing of the above embodiment, and has at least the advantages of low processing cost and high assembly efficiency.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
