Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically a novel radiator core fixing structure. Background Technology

[0002] Traditional radiator cores are fixed using tie rods that hold the side plates together. This requires drilling holes in the pressure plates on both sides of the radiator core, then passing the tie rods through these holes and securing them with nuts. This method is not only complex, time-consuming, and costly, but also prone to damage if the tie rods loosen, causing them to impact the heat pipes and leading to leaks. While existing technologies, such as those in patent publication CN207797851U, use bolts and nuts, which greatly simplifies the fixing mechanism, the bolts only tighten at a single point. Due to the small area of ​​force application, stress concentration occurs near this point. Over time, this stress concentration can cause localized deformation of the metal plate around the tightening point, such as dents or bulges, or even permanent damage like indentations or cracks. This affects the integrity and normal use of the metal plate, further impacting the durability and stability of the radiator core's fixation.

[0003] Therefore, a new type of radiator core fixing structure is urgently needed to solve the above problems. Utility Model Content

[0005] The fixing assembly includes two pads disposed on the side of the side plate near the heat sink core body. The two pads are connected to the core guard plate. The side plate has four threaded holes arranged symmetrically in pairs. Two adjacent threaded holes are respectively disposed opposite to the pads. The four threaded holes are provided with abutting members. The abutting members are provided with pressure-dividing components for reducing stress concentration at the abutting point of the pads.

[0006] The clamping component consists of a fixed plate, threaded rods and fixed posts disposed on both sides of the fixed plate, and the sidewalls of the fixed posts are hexagonal.

[0007] The pressure-dividing assembly includes a fixed cavity formed in the threaded rod, a sliding plate slidably connected to the fixed cavity, and two pressure-dividing rods connected to the side of the sliding plate near the pad via a connecting assembly. The two pressure-dividing rods are arranged crosswise. Two inclined guide sleeves are fixedly connected to the inner wall of the fixed cavity. The ends of the two pressure-dividing rods away from the sliding plate are slidably connected to the guide sleeves. Two inclined holes are formed on the side wall of the threaded rod, and the two inclined holes are concentric with the guide sleeves. The fixed plate is provided with a driving assembly for driving the two pressure-dividing rods. The side of the two pressure-dividing rods near the pad has an inclined surface.

[0008] The sliding plate has two square surfaces near the side wall of the fixed cavity, and the two square surfaces are matched with the inner wall of the fixed cavity.

[0009] The connecting assembly includes two symmetrically arranged connecting plates fixedly connected to the side of the pressure dividing rod near the sliding plate. A mounting plate is connected between the two connecting plates via a rotating shaft. The mounting plate is connected to the sliding plate via a guide assembly.

[0010] The guide assembly includes a dovetail groove formed on the side of the sliding plate near the pressure dividing rod, and a dovetail plate is slidably connected to the dovetail groove. One side of the dovetail plate is connected to the mounting plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1-6 The figure shows a novel radiator core fixing structure, including a radiator core body 1 and core guard plates 2 disposed on both sides of the radiator core body 1. The two core guard plates 2 are provided with side plates 3 on the side away from the radiator core body 1. The two side plates 3 are connected to the radiator shell by multiple bolts. It also includes fixing components disposed on the two side plates 3 for fixing the radiator core body 1.

[0024] The fixing assembly includes two pads 4 disposed on the side of the side plate 3 near the heat sink core body 1. The two pads 4 are connected to the core guard plate 2. The side wall of the side plate 3 has four threaded holes 5 arranged symmetrically in pairs. The two adjacent threaded holes 5 are respectively arranged opposite to the pads 4. The four threaded holes 5 are provided with abutting members 6. The abutting members 6 are provided with a pressure-dividing assembly for reducing the stress concentration at the abutting point of the pads 4.

[0025] It should be noted that: by setting up the fixing components, the heat sink core body 1 is installed and fixed under the pressure of the clamping member 6 against the pad 4. The operation is simple and convenient, which not only improves the installation efficiency of the heat sink core body 1, but also reduces the production cost. At the same time, the modular design of the pad 4 reduces the risk of damage to the heat pipe. Furthermore, under the action of the pressure dividing component, the clamping points of the pad 4 are increased, thereby reducing the stress concentration at a single force point. This reduces the risk of damage to the pad 4 due to local stress concentration, thereby improving the durability and stability of the pad 4 in fixing the heat sink core body 1.

[0026] It is worth noting that the specific structure and working principle of radiators are already known to those in the field, and will not be elaborated upon here.

[0027] Please see Figure 4 The clamping member 6 in the figure consists of a fixed plate 601 and threaded rods 602 and fixed posts 603 disposed on both sides of the fixed plate 601. The side wall of the fixed post 603 is set in a regular hexagon.

[0028] It should be noted here that the setting of the clamping part 6 makes it easy to clamp and fix the pad 4.

[0029] Please see Figures 4-6 The pressure-dividing assembly shown in the figure includes a fixed cavity 701 opened in the threaded rod 602. A sliding plate 702 is slidably connected to the fixed cavity 701. Two pressure-dividing rods 703 are connected to the side of the sliding plate 702 near the pad 4 through a connecting assembly. The two pressure-dividing rods 703 are arranged crosswise. Two inclined guide sleeves 704 are fixedly connected to the inner wall of the fixed cavity 701. The ends of the two pressure-dividing rods 703 away from the sliding plate 702 are slidably connected to the guide sleeves 704. Two inclined holes 705 are opened on the side wall of the threaded rod 602. The two inclined holes 705 are concentrically arranged with the guide sleeves 704. The fixed plate 601 is provided with a driving assembly for driving the two pressure-dividing rods 703. The side of the two pressure-dividing rods 703 near the pad 4 has an inclined surface.

[0030] It should be noted here that by setting up the pressure divider component, the number of pressing points on the pad 4 is increased, thereby reducing the stress concentration at a single force point. This reduces the risk of damage to the pad 4 due to local stress concentration, thereby improving the durability and stability of the pad 4 in fixing the radiator core body 1.

[0031] Please see Figure 6 In the figure, the sliding plate 702 has two square surfaces 706 near the side wall of the fixed cavity 701, and the two square surfaces 706 are matched with the inner wall of the fixed cavity 701.

[0032] It should be noted that two square surfaces 706 are provided on the side wall of the sliding plate 702 to guide and limit the movement of the sliding plate 702.

[0033] It is worth noting that: within the travel of the sliding plate 702, the fixed cavity 701 has square grooves on its sidewall that match the two square surfaces 706.

[0034] Working principle: When installing and fixing the radiator core body 1, first place the radiator core body 1 along with the core protective plates 2 on both sides into the housing, and then connect the two side plates 3 to the housing. After connecting the two side plates 3 to the housing, the clamping member 6 can be installed. During the installation of the clamping member 6, the handle is used to screw the fixing post 603 in, and then the thread engagement between the threaded rod 602 and the threaded hole 5 causes the threaded rod 602 to move closer and closer to the pad 4 on the side wall of the core protective plate 2. As the fixed post 603 is continuously rotated, one end of the threaded rod 602 abuts against the pad 4. The same operation method is used to install the other clamping parts 6. After the multiple clamping parts 6 are installed, the heat sink core body 1 can be installed and fixed under the clamping action of the clamping parts 6 against the pad 4. The operation is simple and convenient, which not only improves the installation efficiency of the heat sink core body 1, but also reduces the production cost. At the same time, the modular design of the pad 4 reduces the risk of damage to the heat sink tube.

[0035] After the clamping member 6 abuts against the pad 4, the driving assembly drives the sliding plate 702 to move within the fixed cavity 701. Under the pushing action of the sliding plate 702 and the guiding action of the guide sleeve 704, the two pressure-dividing rods 703 move crosswise and move out of the inclined hole 705 on the side wall of the threaded rod 602. As the sliding plate 702 continues to move, the inclined surfaces at one end of the two pressure-dividing rods 703 will abut against the surface of the pad 4. The clamping action of the two pressure-dividing rods 703 increases the clamping points on the pad 4, thereby increasing the stress points on the pad 4 and reducing the risk of damage to the pad 4 due to local stress concentration. This improves the durability and stability of the pad 4 in fixing the radiator core body 1.

[0036] Example 2

[0037] Please see Figure 6 This embodiment further illustrates Example 1. The connecting assembly shown in the figure includes two symmetrically arranged connecting plates 801 fixedly connected to the pressure dividing rod 703 on the side near the sliding plate 702. The two connecting plates 801 are connected to a mounting plate 803 through a rotating shaft 802. The mounting plate 803 is connected to the sliding plate 702 through a guide assembly.

[0038] It should be noted here that: through the setting of the connecting components, under the action of the guide components, the pressure dividing rod 703 and the sliding plate 702 are hinged and slidably connected, thereby providing space for the oblique movement of the pressure dividing rod 703.

[0039] Please see Figure 6 The guide assembly shown in the figure includes a dovetail groove 10 opened on the side of the sliding plate 702 near the pressure dividing rod 703. The dovetail groove 10 is slidably connected to a dovetail plate, and one side of the dovetail plate is connected to the mounting plate 803.

[0040] It should be noted here that the guide component is used to provide guidance and limit the movement of the mounting plate 803.

[0041] Example 3

[0042] Please see Figure 4 and Figure 5 This embodiment is a further description of other embodiments. The driving assembly shown in the figure includes a lead screw 901 rotatably connected to a fixed disk 601. A driving tube 902 is threadedly connected to the side wall of the lead screw 901. One end of the driving tube 902 is connected to a sliding plate 702. The end of the lead screw 901 away from the driving tube 902 passes through a fixed post 603 and has a driving hole 903 with a regular hexagonal shape.

[0043] It should be noted that, through the configuration of the drive assembly, when the sliding plate 702 needs to be moved, an Allen wrench is inserted into the drive hole 903 at one end of the lead screw 901. During the rotation of the Allen wrench, the lead screw 901 can be rotated synchronously. Then, under the threaded meshing transmission of the lead screw 901 and the drive tube 902, the guidance of the square surface 706 on the side wall of the sliding plate 702 and the fixed cavity 701, and the guidance of the pressure dividing rod 703 and the guide sleeve 704, the sliding plate 702 is moved within the fixed cavity 701.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
