Description

Technical Field

[0001] This utility model belongs to the technical field of hybrid mining cards, specifically relating to a hybrid mining card heat sink. Background Technology

[0002] Hybrid mining trucks (HMCs) are a type of engineering vehicle equipped with a three-electric system (motor, controller, and battery) for loading goods such as ore and soil. Because the three-electric system of a hybrid mining truck requires heat dissipation, existing hybrid mining trucks often use a single radiator for ease of layout. This single radiator cools both the motor and controller in the three-electric system simultaneously. In this layout, there are significant variations in coolant flow rate, water resistance, head, and heat dissipation power across different circuits. To ensure effective cooling of the motor and controller, a large redundancy is always included in the radiator selection, resulting in a large actual working volume. This not only increases costs but also occupies a significant amount of space, severely limiting the usable space for other components inside the hybrid mining truck and increasing the difficulty of utilizing interior space. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hybrid mining truck radiator to solve the technical problems of excessive redundancy in the design of hybrid mining trucks in the prior art, which leads to increased production costs and increased difficulty in utilizing the interior space.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hybrid mining card heat sink, comprising:

[0005] At least two small radiators are arranged side by side, and each small radiator has a liquid inlet and a liquid outlet;

[0006] A protective plate ring sleeve, wherein the protective plate ring sleeve is composed of a plurality of protective plates, and the plurality of protective plates are arranged around the outer periphery of the small radiator;

[0007] A fan assembly is located on one side of the small heat sink and is connected to the protective plate ring.

[0008] This invention utilizes multiple small radiators instead of a single radiator. Each small radiator corresponds to the three-electric system of the hybrid mining truck according to its own heat dissipation capacity. This allows the components such as the motor and controller in the three-electric system to be better matched with their respective small radiators based on their own heat generation capacity, reducing redundancy and achieving the goals of reducing costs and improving temperature control accuracy.

[0009] Further: the fan assembly includes:

[0010] Protective shield;

[0011] Several fans are distributed and embedded in the protective cover;

[0012] A plurality of partitions are disposed inside the protective cover, and the partitions separate the fan.

[0013] The benefits of this step: Fans generally have an intake side and an exhaust side. By connecting the exhaust side of the fan to the shield through the cover, it is ensured that the air blown out by the fan will not escape and can pass completely through the heat sink, thus improving the heat exchange effect.

[0014] The partition separates each fan to prevent them from interfering with each other.

[0015] Furthermore, the surface of the protective cover is also provided with several wire harness fixing brackets.

[0016] The benefits of using this step are: the wire harness holder makes it easy to securely connect the wire harnesses of each fan.

[0017] Furthermore: the top surface of the protective plate ring is provided with at least two lifting lugs;

[0018] The bottom surface of the guard ring is provided with at least two mounting seats;

[0019] The mounting base includes a rigid pad and a flexible pad. The rigid pad is connected to the guard plate ring, and the flexible pad is located below the rigid pad.

[0020] The beneficial effects of this step are: the radiator of this application can be stably hoisted by at least two lifting lugs; the mounting base has a shock absorption effect.

[0021] Furthermore, the mounting base has several through holes, and anti-loosening washers are provided on the through holes. The anti-loosening washers are composed of an upper rigid washer and a lower flexible washer.

[0022] The benefits of this step include: the anti-loosening washer prevents the fasteners used for installation from coming loose.

[0023] Furthermore: a protective plate is provided at the apex corner of the protective plate ring;

[0024] The protective plate includes a vertical section and a bent section. The vertical section is connected to the side of the protective plate collar. The angle between the vertical section and the bent section is between 90° and 180°.

[0025] At least one reinforcing rib is also provided between the vertical section and the bent section.

[0026] The beneficial effect of this step is that the protective plate prevents debris from hitting the radiator.

[0027] Furthermore: both sides of the protective plate ring are provided with auxiliary connecting blocks, each auxiliary connecting block has at least one threaded hole, and the top surface of the auxiliary connecting block is provided with the flexible washer corresponding to the threaded hole.

[0028] The benefits of this step include: connecting the side of the radiator to other components or structural parts, further improving the stability of the radiator installation.

[0029] The beneficial effects of this utility model are:

[0030] 1. This application uses multiple small heat sinks to replace the original heat sinks, allowing the multiple small heat sinks to be matched with the motors and controllers in the three-electric system according to their own heat dissipation capacity and heat generation capacity, which can reduce the design redundancy of the small heat sinks, thereby achieving the purpose of reducing production costs and space occupation.

[0031] 2. Install multiple small heat sinks together using the protective plate ring, and combine them with multiple fans in the fan assembly. By adjusting the different working states of each fan, precise temperature control can be achieved for each small heat sink. Attached Figure Description

[0048] Example

[0049] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the hybrid mining card radiator provided by this utility model includes:

[0050] At least two small radiators 1 are arranged side by side, and each small radiator 1 has a liquid inlet and a liquid outlet; in the three-electric system of the hybrid mining truck, the controller and motor generate a lot of heat and require auxiliary heat dissipation. At this time, only two small radiators 1 are needed, which are connected to the controller and the motor respectively.

[0051] The protective plate ring 2 is composed of several protective plates. The several protective plates are wrapped around the outer periphery of the small radiator 1. The protective plates are generally channel-shaped steel plates with bent sides. Multiple protective plates are connected end to end to form a ring. The small radiator 1 is embedded in the groove.

[0052] The fan assembly 3 is located on one side of the small heat sink 1 and is connected to the protective plate ring 2 to ensure that the air is not dissipated.

[0053] This invention utilizes multiple small radiators 1 to replace the overall radiator. Each small radiator 1 corresponds to the three-electric system of the hybrid mining truck according to its own heat dissipation capacity, so that the motor, controller and other components in the three-electric system are better matched with their respective small radiators 1 according to their own heat generation capacity, reducing redundancy, and achieving the purpose of reducing costs and improving temperature control accuracy.

[0054] Based on the above technical solution, the fan assembly 3 includes:

[0055] Shield 31;

[0056] Several fans 32 are distributed and embedded on the protective cover 31. The fans 32 are generally axial fans.

[0057] A plurality of partitions 33 are disposed inside the protective cover 31, and the partitions 33 separate the fan 32.

[0058] Fan 32 generally has an air intake side and an air exhaust side. The air exhaust side of fan 32 is connected to the protective plate ring 2 through the cover 31, thereby ensuring that the air blown out by fan 32 will not escape and can pass completely through the small heat sink 1, thus improving the heat exchange effect.

[0059] The partition 33 separates each fan 32 to prevent the fans 32 from interfering with each other.

[0060] by Figure 3 and Figure 4 For example, the number of fans 32 on the fan assembly 3 can be five or six, or other numbers, depending on the size of the multiple small heat sinks 1 and the actual required heat exchange airflow.

[0061] Based on the above technical solution, the surface of the protective cover 31 is also provided with several wire harness fixing brackets 34.

[0062] The wire harness fixing bracket 34 is welded to the outer surface of the cover 31. The wire harness fixing bracket 34 is used to conveniently fix the wire harnesses of each fan to ensure that the wire harnesses are neat, beautiful and firmly fixed.

[0063] Based on the above technical solution, the top surface of the protective plate ring 2 is provided with at least two lifting lugs 21;

[0064] The bottom surface of the guard ring 2 is provided with at least two mounting seats 22;

[0065] The mounting base 22 includes a rigid pad and a flexible pad. The rigid pad is connected to the guard plate ring 2, and the flexible pad is located below the rigid pad. The rigid pad is generally a metal block of the same material as the guard plate, and the two are welded together. The flexible pad is generally made of rubber or plastic material, or it may be made of felt material.

[0066] The radiator of this application can be hoisted stably by using at least two lifting lugs 21; the flexible pad in the mounting base 22 has a shock absorption effect. The working environment of the hybrid mining truck is harsh, with poor road conditions, many bumps and large vibrations. Without a good shock absorption effect, the radiator of this application is easily damaged.

[0067] Based on the above technical solution, the mounting base 22 is provided with several through holes, and anti-loosening washers 23 are provided on the through holes. The anti-loosening washers 23 are composed of an upper rigid washer and a lower flexible washer.

[0068] Anti-loosening washers 23 prevent fasteners used for installation from loosening. Rigid washers and rigid pads are made of the same material, and flexible washers and flexible pads are made of the same material.

[0069] Based on the above technical solution, a protective plate 25 is provided at the top corner of the protective plate ring 2;

[0070] The protective plate 25 includes a vertical section and a bent section. The vertical section is connected to the side of the protective plate collar 2. The angle between the vertical section and the bent section is between 90° and 180°. This angle can guide the falling ore to slide outward after hitting the protective plate 25.

[0071] At least one reinforcing rib is provided between the vertical section and the bending section to improve the structural strength.

[0072] When hybrid mining trucks are working in the mining area, especially during loading, the ore may fall into the gap between the truck head and the truck body. This gap is usually where the radiator is installed. The ore may damage the radiator. Therefore, a protective plate 25 is installed on the top corner of the radiator. The protective plate 25 serves to prevent debris from hitting the radiator.

[0073] Based on the above technical solution, auxiliary connecting blocks 24 are provided on both sides of the guard ring 2. At least one threaded hole is provided on the auxiliary connecting block 24, and the flexible washer is provided on the top surface of the auxiliary connecting block 24 corresponding to the position of the threaded hole.

[0074] Connecting the side of the radiator to other components or structural parts further improves the stability of the radiator installation.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
