[0044] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0045] Example 1

[0046] As mentioned in the background section, in view of the problems in the prior art, this embodiment provides a solenoid valve controller with enhanced heat dissipation function, including:

[0047] The outer casing 1 has a first open end, and a first space is formed inside the casing. Multiple solenoid valves 2 are provided in the first space.

[0048] The heat dissipation structure includes a heat sink 3, which is located at the first opening end. The end of the heat sink 3 that is close to the solenoid valve is located in the first space, and the end that is away from the solenoid valve extends out of the housing 1 from the first opening end, so as to conduct the heat generated by the multiple solenoid valves 2 to the external environment.

[0049] like Figures 1-16 As shown, the outer shell 1 is approximately a cuboid shell, with the first horizontal direction being the length direction of the outer shell 1, and the first space being the internal space of the outer shell 1. The first space is connected to the external environment through the first opening end. Multiple solenoid valves 2 are evenly arranged on the PCB board and are connected to the external power supply and the working component 7 through wire harnesses and air pipes, respectively, to control the expansion and contraction of the working component 7 or to maintain the inflation / deflation state when powered on. The heat sink 3 is provided on the outer shell 1 and is made of aluminum or copper. The circumferential contour of the heat sink 3 matches the inner contour of the first opening end so that the heat sink 3 is set at the first opening end and fixed to the outer shell 1 by an integrated injection molding / adhesion / screwing / welding / thermal riveting method. One end of the heat sink 3 is located in the first space, and the other end extends out of the outer shell 1 from the first opening end. It conducts the heat generated by the solenoid valve 2 to the external environment through its own good thermal conductivity.

[0050] By setting a heat sink 3 at the first opening end of the outer casing 1, with one end of the heat sink 3 located in the first space and the other end extending to the external environment through the first opening end, the heat generated by the multiple solenoid valves 2 in the first space can be conducted to the outside of the controller, thereby dissipating heat from the solenoid valves 2 and helping to extend the service life of the solenoid valves 2.

[0051] In a preferred embodiment, the outer casing 1 includes a housing 11 and a cover 12 that are interlocked, and the housing 11 or the cover 12 has a first open end.

[0052] like Figure 4 , Figure 8 , Figure 12 and Figure 16 As shown, the housing 11 has multiple limiting grooves that match the outer contour of the solenoid valve 2 for mounting the solenoid valve 2. The housing 11 also has multiple snap-fit ​​parts in its circumference. The cover 12 is approximately a rectangular planar structure, and its circumference has multiple buckles that correspond one-to-one with the snap-fit ​​parts. The snap-fit ​​parts engage with the housing 11 and the cover 12 to form the outer shell 1. Figure 4 , Figure 8 and Figure 12 As shown, when the cover 12 has a first opening, multiple solenoid valves 2 are fixed to the housing 11 via a PCB board. The two ends of the solenoid valves 2 are embedded in limiting grooves, and the heat sink 3 is closed at the first opening. Figure 16 As shown, when the housing 11 has a first opening, multiple solenoid valves 2 are fixed to the cover 12 via a PCB board, and the two ends of the solenoid valves 2 are embedded in the limiting grooves; furthermore, the housing 11 and the cover 12 are made of aluminum / copper or graphene.

[0053] In a preferred embodiment, the heat dissipation structure further includes a flexible heat conductor 4, the two ends of which abut against the heat sink 3 and a plurality of solenoid valves 2, respectively.

[0054] like Figure 4 , Figure 8 , Figure 12 and Figure 16 As shown, the flexible heat conductor 4 is made of non-metallic materials with high thermal conductivity, such as thermally conductive silicone, thermally conductive grease, thermally conductive gel, etc. The above materials have a certain elasticity or fluidity after being heated, which can effectively fill the gap between the contact surfaces of the outer surface of the solenoid valve 2 and the heat sink 3 when they are in direct contact, further enhancing the heat conduction effect. The flexible heat conductor 4 can be fixed on the side of the heat sink 3 near the solenoid valve 2, or the flexible heat conductor 4 can be injected between multiple solenoid valves 2.

[0055] In a preferred embodiment, the outer shell 1 is further provided with heat dissipation holes 121, and the plurality of heat dissipation holes 121 are respectively connected to the first space.

[0056] like Figure 7 As shown, the first opening end has a connecting part above each of the two ends along the length direction of the housing 11. The connecting part has a through hole that runs through the connecting part along the length direction of the housing 1. The through hole communicates with the first space. The side of the through hole away from the heat sink 3 is sealed by a plug 124 to form the heat dissipation hole 121. The heat dissipation hole 121 is used to dissipate the heat in the first space to the external environment.

[0057] In a preferred embodiment, a cover 122 is provided at both ends of the first opening end along the first horizontal direction. The two covers 122 are respectively surrounded by the heat sink 3 to form a heat dissipation channel 123. A plurality of heat dissipation holes 121 are connected to the first space through the corresponding heat dissipation channel 123.

[0058] like Figure 11 and Figure 17 As shown, two covers 122 are disposed on the cover 12 and respectively cover the two ends of the first opening along the length of the outer shell 1, located above the heat dissipation substrate 31. The heat dissipation fins 32 / heat dissipation fins 33 / protrusions 34 on the heat dissipation substrate 31 corresponding to the positions of the covers 122 can abut against the inner wall of the covers 122 and form multiple heat dissipation channels 123 together with the inner wall of the covers 122. The heat dissipation fins 32 / heat dissipation fins 33 / protrusions 34 on the heat dissipation substrate 31 not covered by the covers 122 extend to be flush with the covers 122. Multiple heat dissipation holes 121 are connected to the first space through the corresponding heat dissipation channels 123. By setting the heat dissipation channels 123, the noise generated by the heat dissipation holes 121 during the use of the controller can be reduced. At the same time, the airflow flowing through the heat dissipation channels 123 contacts the heat sink 3 and can carry away the heat of the heat sink 3, assisting the heat sink 3 in heat dissipation.

[0059] like Figure 15As shown, when the housing 11 has a first open end, two covers 122 are disposed on the housing 11 and respectively cover the two ends of the first open end along the length direction of the outer shell 1, located below the heat dissipation substrate 31. The heat dissipation fins 32 / heat dissipation fins 33 / protrusions 34 on the heat dissipation substrate 31 corresponding to the positions of the covers 122 can abut against the inner wall of the covers 122 and form multiple heat dissipation channels 123 together with the inner wall of the covers 122. In some embodiments, the heat dissipation fins 32 / heat dissipation fins 33 / protrusions 34 on the heat dissipation substrate 31 that are not covered by the covers 122 can also extend to be flush with the covers 122. Multiple heat dissipation holes 121 communicate with the first space through the corresponding heat dissipation channels 123.

[0060] like Figure 18 As shown, the inner wall of the cover 122 has an extension that abuts against the heat dissipation fins 32 / 33 / protrusions 34, which can eliminate the noise generated when the gas passes through and control the gas flow direction. The heat dissipation channel 123 formed by the cover 122 and the heat dissipation fins 3 is not limited to the above form. The internal structure of the cover 122 can also be adjusted according to the structure on the heat dissipation substrate 31. Other methods can also be used to reduce noise.

[0061] In a preferred embodiment, the heat sink 3 includes a heat dissipation substrate 31.

[0062] In a preferred embodiment, a plurality of heat dissipation fins 32 are arranged in a matrix on the side of the heat dissipation substrate 31 away from the solenoid valve 2.

[0063] In a preferred embodiment, a plurality of heat dissipation fins 33 are provided at equal intervals on the side of the heat dissipation substrate 31 away from the solenoid valve 2.

[0064] In a preferred embodiment, a plurality of protrusions 34 are evenly distributed on the side of the heat dissipation substrate 31 away from the solenoid valve 2.

[0065] like Figures 19-22 As shown, the heat sink 3 includes a heat sink substrate 31, which is a rectangular planar structure made of copper. Heat sink fins 32 / heat sink fins 33 / protrusions 34 can be provided on the side of the heat sink substrate 31 away from the solenoid valve 2 to increase the contact area with air and enhance the heat dissipation effect of the heat sink 3. The heat sink fins 32 are toothed copper sheets arranged in a matrix on the heat sink substrate 31. The heat sink fins 33 are long strip copper sheets, and multiple heat sink fins 33 are distributed on the heat sink substrate 31 along the width direction of the outer shell and extend along the length direction of the outer shell. An air channel is formed between two adjacent heat sink fins 33. Multiple serrated protrusions 34 are evenly distributed on the heat sink substrate 31, and serrated grooves are formed between adjacent protrusions 34.

[0066] Example 2

[0067] This embodiment provides an automobile seat, including a solenoid valve controller as described in Embodiment 1.

[0068] like Figure 23 As shown, it also includes a back plate 5, a frame 6, a working component 7, and a carrier 8. The solenoid valve controller is connected to the working component 7 through an air pipe and is set on the carrier 8 together. The frame 6 is set on the carrier 8, and the frame 6 can support the carrier 8. The back plate 5 covers the carrier 8 and is used to wrap the working component 7.

[0069] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. The above descriptions are only preferred embodiments of this application. It should be noted that due to the limitations of written expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this invention, and can also combine the above technical features in an appropriate manner.
