Description
Technical Field
[0001] The utility model relates to the technical field of radiators, and particularly to a radiator module. The utility model also relates to a vehicle-mounted terminal provided with the radiator module. Background Art
[0002] With the increasing functions of vehicle-mounted terminals such as vehicle-mounted multimedia hosts and intelligent driving controllers, the heat generated by their chips is also increasing. To this end, heat dissipation can be achieved by externally connecting a radiator to the main chip.
[0003] In order to ensure the close fit between the chip and the radiator, most manufacturers adopt solutions such as laying a thermal pad or applying a thermal gel between the chip and the radiator. Due to the tolerances of the chip itself and the radiator, and the warping problem of the PCBA, this kind of heat dissipation solution will apply a thicker thermal gel or thermal pad between the chip and the radiator to absorb this part of the tolerance, reducing the rate of heat conduction from the chip to the radiator.
[0004] Although the heat transfer rate between the chip and the radiator can be improved by adjusting the assembly force between the radiator and the chip. However, if the radiator and the chip are assembled too tightly, there is a risk of damaging the chip; if the assembly is too loose, there will be a problem that the radiator cannot contact the chip and cannot conduct heat quickly.
[0005] Therefore, how to ensure the heat dissipation rate while protecting the chip is a technical problem to be solved urgently. Summary of the Utility Model
[0006] The purpose of the utility model is to provide a radiator module to solve the above technical problems.
[0007] Another purpose of the utility model is to provide a vehicle-mounted terminal provided with the radiator module.
[0008] To achieve the above purpose, a radiator module provided by the utility model includes a radiator body and a radiator mounting component. The radiator mounting component includes mounting elastic pieces located on both sides of the bottom of the radiator body. Each mounting elastic piece respectively includes a first connection end, a second connection end, and an elastic deformation part connected between the first connection end and the second connection end. The first connection end is connected to the side surface of the radiator body, the second connection end is a fixed connection end, and the elastic deformation part can elastically deform in a direction perpendicular to the bottom of the radiator body.
[0009] Optionally, the first connection end extends vertically from the elastic deformation part towards the direction close to the bottom of the radiator body, and the second connection end extends vertically from the elastic deformation part towards the direction away from the bottom of the radiator body.
[0010] Optionally, the first connection end is located in a first vertical plane, and the second connection end is located in a second vertical plane; the first vertical plane is attached to the side surface of the radiator body, and there is a spaced distance between the second vertical plane and the side surface of the radiator body.
[0011] Optionally, the elastic deformation part includes at least one bending part, and the bending part has an opening facing the side surface of the radiator body.
[0012] Optionally, the bending part is in a C shape, U shape, V shape, W shape, S shape or Z shape.
[0013] Optionally, the second connection end is provided with a rim convex part, and the rim convex part extends towards the side surface of the radiator body and is provided with an internal thread for fixing by a screw;
[0014] The internal thread of the rim convex part has a length of at least three times the pitch of the screw.
[0015] Optionally, at least two of the mounting elastic pieces are provided on each side of the radiator body, and / or the mounting elastic pieces on both sides of the radiator body are symmetrically arranged.
[0016] To achieve the above-mentioned another purpose, the present invention provides a vehicle-mounted terminal, including a housing, a chip and the radiator module according to any one of the above; the housing is provided with a heat dissipation space for accommodating the radiator module, and the second connection ends of the mounting elastic pieces are fixedly connected to the side wall of the heat dissipation space, and the mounting elastic pieces elastically deform so that the heat conduction component at the bottom of the radiator body is elastically in contact with the chip.

[0019] The heat sink module provided by the present utility model is provided with mounting elastic pieces on both sides of the heat sink body. The heat sink module can be mounted at the required position through the mounting elastic pieces. Since the mounting elastic pieces have elastic deformation portions, after mounting, the elastic deformation portions can elastically deform in the direction perpendicular to the bottom of the heat sink body, thereby generating an elastic deformation acting force, enabling the bottom of the heat sink body to be in direct or indirect elastic contact with the component to be cooled, making the two closely fit, and compensating for the tolerances existing in the related components. In this way, the interface materials (such as thermal conductive gel, thermal conductive silicone grease, etc.) coated on the surface of the component to be cooled for heat dissipation are significantly thinned, thereby minimizing the thermal resistance as much as possible, increasing the rate at which the heat of the component to be cooled is conducted to the heat sink body. At the same time, since the elastic force can be controlled within a reasonable range, the component to be cooled will not be damaged.
[0020] The vehicle-mounted terminal provided by the present utility model is provided with the heat sink module.

[0033] To enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.
[0034] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings. Depending on the different drawings, the corresponding positional relationship may also change accordingly. Therefore, it cannot be understood as an absolute limitation of the protection scope; moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.
[0035] Please refer to Figure 1 、 Figure 2 , Figure 1 which is the structural schematic diagram of the radiator module provided by the first embodiment of the present utility model; Figure 2 is Figure 1 the cross-sectional view of the shown mounting spring piece.
[0036] As shown in the figure, in a specific embodiment, the radiator module 10 provided by the present utility model mainly consists of a radiator body 11 and radiator mounting components. Among them, the radiator mounting components include mounting spring pieces 12 located on both sides of the bottom of the radiator body 11. Each mounting spring piece 12 has a first connection end 121, a second connection end 122, and an elastic deformation part 123. The first connection end 121 is connected to the side surface of the radiator body 11. The second connection end 122 is a fixed connection end for fixing the entire radiator module 10. The elastic deformation part 123 is connected between the first connection end 121 and the second connection end 122. Since the elastic deformation part 123 is bent in a bow shape, it can elastically deform in the direction perpendicular to the bottom of the radiator body 11.
[0037] Compared with the solution of directly and rigidly fixing the radiator module 10, since the mounting spring piece 12 has an elastic deformation part, after installation, the elastic deformation part 123 can elastically deform in the direction perpendicular to the bottom of the radiator body 11, thereby generating an elastic deformation acting force, enabling the bottom of the radiator body 11 to be elastically in contact with the component to be cooled directly or indirectly (such as through the heat-conducting component 13 below), making the two closely fit, so as to compensate for the tolerances existing in related components such as the radiator body 11, the component to be cooled, and the circuit board. Therefore, the thickness of the interface material 15 such as thermal conductive gel and thermal conductive silicone grease between the component to be cooled and the bottom of the radiator body 11 can be greatly reduced, thereby greatly reducing the thermal resistance between the component to be cooled and the radiator module 10, increasing the rate of heat conduction from the component to be cooled to the radiator body 11. At the same time, since the elastic force can be controlled within a reasonable range, it will not damage the component to be cooled.
[0038] In this embodiment, as an implementation manner in which the radiator body 11 is indirectly in contact with the component to be cooled, a heat-conducting component 13 is provided at the bottom of the radiator body 11. A heat pipe 14 is provided between the heat-conducting component 13 and the radiator body 11. The evaporation section of the heat pipe 14 is connected to the heat-conducting component 13, and the condensation section of the heat pipe 14 is connected to the radiator body 11; in the use state, the radiator body 11 is located above the heat-conducting component 13, and the condensation section of the heat pipe 14 is located above the evaporation section.
[0039] During use, the heat-conducting component 13 is used to contact components to be cooled such as the chip 32, etc., so as to transfer the heat generated by the components to be cooled such as the chip during the working state to the heat-conducting component 13. The evaporation section of the heat pipe 14 can stably obtain heat from the components to be cooled such as the chip through the heat-conducting component 13, and then transfer the absorbed heat to the radiator body 11 at the condensation section of the heat pipe 14, and further dissipate heat through the radiator body 11.
[0040] The heat-conducting component 13 has high thermal conductivity, and its material can be metal. The heat-conducting component 13 can be in a block shape or a plate shape. Optionally, the heat-conducting component is a copper block.
[0041] The radiator body 11 can be a radiator with any structure. The first connection end 121 of the mounting spring piece 12 can be fixedly connected to the side surface of the radiator body 11 by screws, so as to be assembled with the radiator body 11.
[0042] Specifically, the mounting spring piece 12 is a metal sheet structure with elasticity, and it is integrally in a strip shape with equal width.
[0043] Such as Figures 1 to 4As shown, the first connection end 121 and the second connection end 122 of the mounting spring 12 are both parallel to the side of the radiator body 11, the first connection end 121 extends vertically from the lower end of the elastic deformation portion 123 toward the bottom of the radiator body 11, that is, extends downward as shown in the figure, and the second connection end 122 extends vertically from the upper end of the elastic deformation portion 123 toward the bottom of the radiator body 11, that is, extends upward as shown in the figure, the elastic deformation portion 123 is a V-shaped bending portion, and the opening of the bending portion faces the side of the radiator body 11.
[0044] The second connection end 122 is provided with a rim protrusion 1221, which is a cylindrical flange shape, extending to the side of the radiator body 11 and forming an internal thread by tapping. The internal thread of the rim protrusion 1221 has a length of at least three times the pitch of the screw 1222 so that it has a certain locking strength. The entire radiator module 10 can be fixedly connected to an installation object such as a structural shell through the rim protrusion 1221 using screws 1222.
[0045] The first connection end 121 is located on the first vertical plane a, and the second connection end is located on the second vertical plane b. The second vertical plane b is offset outward relative to the first vertical plane a, and there is a distance between the second vertical plane b and the side surface of the radiator body 11. In other words, the first connection end 121 and the second connection end 122 of the installation spring 12 are not located on the same plane, but are offset from each other, and the second connection end 122 is located on the side of the first connection end 121 away from the radiator body 11. Therefore, sufficient installation space can be reserved for the rim protrusion 1221 to be fixedly connected by the screw 1222, so as to avoid the screw 1222 from contacting the radiator body 11.
[0046] In actual use, the number of mounting springs is selected according to the size of the radiator body 11. At least two mounting springs 12 can be provided on both sides of the radiator body 11, and the mounting springs 12 on both sides of the radiator body 11 can be symmetrically arranged, as long as the mounting springs 12 can be evenly distributed on the radiator body 11.
[0047] It is understandable that the mounting spring sheet 12 needs to have a certain elasticity. After the bottom of the radiator body 11 is subjected to force, the mounting spring sheet 12 can be deformed in the vertical direction. Therefore, it can be any metal sheet with elastic shape. For example, the bending part of the mounting spring sheet 12 is U-shaped toward the opening of the radiator body 11 (see FIG. Figure 3 , Figure 4 ), or, W-shaped, and so on.
[0048] Meanwhile, the length, width of the mounting spring piece 12 and the number of fixing screws can be analyzed and designed according to the actual situation, so that the force required for the mounting spring piece 12 to undergo elastic deformation is controlled within a reasonable range, which will neither damage the chip and other heat dissipation components, nor cause the radiator body 11 to separate from the surface of the chip and other heat dissipation components during vibration.
[0049] The above embodiments are only the preferred solutions of the present utility model, and are not specifically limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation manners. For example, the first connection end 121 and the second connection end 122 of the mounting spring piece 12 can also be fixed by means such as welding, riveting, clamping, bonding, etc. Or, the elastic deformation part 123 of the mounting spring piece 12 is in other shapes such as an S shape, a Z shape or a C shape, etc. Since there are many possible implementation manners, they will not be exemplified one by one here.
[0050] Please refer to Figures 7 to 10 , Figure 7 which is a schematic structural diagram of a vehicle-mounted terminal provided by an embodiment of the present utility model; Figure 8 is Figure 7 the A-A cross-sectional view of Figure 9 is Figure 8 the partial enlarged schematic view of the I part in Figure 10 the schematic view of the heat conduction component at the bottom of the radiator body in elastic contact with the chip.
[0051] In addition to the above radiator module, the present utility model also provides a vehicle-mounted terminal 30, which can be a vehicle-mounted multimedia host, an intelligent driving controller or a vehicle-mounted T-BOX, etc. It is provided with a housing 31, a chip 32, a PCB board 33 and a radiator module 10. The chip 32 is installed on the PCB board 33. The PCB board 33 is located below the radiator module 10, and the radiator module 10 is the radiator module 10 introduced above, which is used to dissipate heat from the chip 32.
[0052] Specifically, the housing 31 is provided with a heat dissipation space for accommodating the radiator module 10. The second connection end 122 of the mounting spring piece 12 of the radiator module 10 is fixedly connected to the side wall 311 of the heat dissipation space by screws 1222 through the rim convex part 1221. After the radiator module 10 is installed on the housing 31, at this time, the mounting spring piece 12 only bears the gravity of the radiator module 10 itself. As the PCB board 32 is installed into the housing 31, the upper surface of the chip 32 contacts the heat conduction component 13 at the bottom of the radiator module 10, applying pressure to the bottom of the radiator module 10, causing the mounting spring piece 12 to deform, so as to ensure that the heat conduction component 13 at the bottom of the radiator module 10 can be in close contact with the upper surface of the chip 32. The effect after assembly is as Figure 10 shown.
[0053] When the device is running, after the chip 32 generates heat, the heat is quickly transferred to the contacted heat-conducting component 13 through the thinly coated interface material 15. Utilizing the high thermal conductivity of the heat-conducting component 13, the heat rapidly diffuses within the heat-conducting component 13 and is transferred to the evaporation section of the heat pipe 14 connected inside the heat-conducting component 13. Subsequently, the heat is rapidly conducted to the condensation section of the heat pipe 14 and gradually transferred to the contacted radiator body 11, where the radiator body 11 conducts sufficient heat dissipation.
[0054] Since an elastic contact fitting relationship is formed between the heat-conducting component 13 and the chip 32, under the elastic force of the mounting spring piece 12, the heat-conducting component 13 can always be pressed tightly against the chip 32. Therefore, a thinner interface material 15 compared to the prior art, such as thermal gel, thermal grease, etc., can be coated between the chip 32 and the heat-conducting component 13, thereby minimizing the thermal resistance as much as possible and increasing the rate of heat conduction from the chip to the radiator body 11.
[0055] To further save the internal space of the housing 31, a hole 312 corresponding to the elastic deformation part of the mounting spring piece 12 is provided on the side wall 311 of the heat dissipation space. This hole 312 is generally rectangular in shape, and at least a part of the elastic deformation part 123 is located in the hole 312. In this embodiment, the elastic deformation part 123 enters the hole 312 from one side of the hole 312 and then extends a certain distance from the other side of the hole 312. Let the distance between the side wall 311 of the heat dissipation space and the side surface of the radiator body 11 be L1, the thickness of the side wall 311 of the heat dissipation space be L2, and the overall width of the mounting spring piece 12 in the direction perpendicular to the side surface of the radiator body 11 be L3, then L3 ≥ L1 + L2.
[0056] In this way, without affecting the elastic deformation of the mounting spring piece 12, the space saved by making way can be used to minimize the width of the heat dissipation space and the size of the housing 31 as much as possible, which is conducive to the miniaturization design of the product.
[0057] The above has introduced the radiator module and in-vehicle terminal provided by the present utility model in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
