Description

Technical Field

[0001] This utility model relates to the field of heat sinks, specifically a modular heat sink. Background Technology

[0002] A heatsink is a device used to dissipate heat from heat-generating electronic components in electrical appliances. It is typically made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. For example, the CPU (Central Processing Unit) in a computer requires a fairly large heatsink, and power transistors, horizontal output transistors, and power amplifier transistors in a television all use heatsinks. Generally, a layer of thermal grease is applied to the contact surface between the electronic component and the heatsink during use. This allows the heat generated by the component to be more effectively conducted to the heatsink, and then dissipated into the surrounding air.

[0003] For example, patent announcement number CN205228248U discloses a heat sink, including a heat sink body and multiple heat-conducting fins. The heat-conducting fins have bottom ends and top ends, with the bottom ends located on the front of the heat sink body and integrally formed with it. Grooves are formed between the bottom ends of multiple adjacent fins longitudinally, and grooves are arranged between multiple adjacent grooves laterally. An adhesive is provided on the back of the heat sink body. The heat sink provided by this utility model, by integrally forming multiple heat-conducting fins and mounting them on the heat sink body, transfers heat to the heat-conducting fins through the heat sink body. It has a simple structure and strong practicality.

[0004] Existing modular heat sinks mostly connect multiple heat sinks and allow for large-area application by using the interlocking of connecting protrusions and grooves on the substrate. However, this method of connection is not strong and is prone to separation and detachment when subjected to external factors (such as collisions). Therefore, there is an urgent need in the market to develop a modular heat sink to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide an assemblable heat sink to solve the problem mentioned in the background art. Most of the existing assemblable heat sinks are connected and used over a large area by the cooperation between the connecting protrusions and connecting grooves on the substrate. However, the connection relationship in this way is not firm and is prone to separation and detachment when subjected to external factors (such as collisions).

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assemblable heat sink, comprising a substrate, two long heat dissipation fins fixedly connected to the middle of the upper end of the substrate, two short heat dissipation fins fixedly connected to both the front and rear ends of the upper end of the substrate, insertion slots provided on both sides of the front end face of the substrate, a first rectangular sliding groove connected to the middle of the inner side of each of the two insertion slots inside the substrate, a first rectangular slider slidably disposed inside the first rectangular sliding groove, one end of the first rectangular slider extending into the insertion slot and fixedly connected to a triangular locking tongue, a second rectangular sliding groove provided on both sides of the rear end face of the substrate, a second rectangular slider slidably disposed inside the second rectangular sliding groove, a trapezoidal locking tongue fixedly connected to the rear end of the second rectangular slider, and a triangular slot provided on one side between the rear end of the second rectangular slider and the trapezoidal locking tongue.

[0007] Preferably, a first guide rod is fixedly connected to one side of the inside of the first rectangular slide groove, a guide groove is provided inside the first rectangular slider, one end of the first guide rod is inserted into the guide groove, and a first spring is provided on the outside of the first guide rod between one side of the first rectangular slider and one side end face of the first rectangular slide groove.

[0008] Preferably, the upper surface of the substrate has a first strip opening on both front ends, and the upper ends of the two first rectangular sliders are fixedly connected with first paddles, which extend out of the upper surface of the substrate through the two first strip openings respectively.

[0009] Preferably, a second guide rod is fixedly connected to the rear end of the second rectangular slide groove, a telescopic groove is provided in the middle of the second rectangular slide, the front end of the second guide rod is inserted into the telescopic groove and fixedly connected to a circular limiting piece, and a second spring is provided on the outside of the second guide rod between the front end of the circular limiting piece and the front end of the telescopic groove.

[0010] Preferably, a second strip-shaped opening is provided at the rear end of both sides of the substrate, and a second lever is fixedly connected to the outer side of each of the two second rectangular sliders. One end of each of the two second levers passes through the second strip-shaped opening and extends out of the side end of the substrate.

[0011] Preferably, the two substrates are connected by a trapezoidal locking tongue at the rear end of a second rectangular slider on one substrate extending out of a second rectangular groove and inserting into a slot on the other substrate.

[0012] Preferably, after the trapezoidal locking tongue is inserted into the insertion slot, the triangular locking tongue is inserted into the triangular slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention significantly enhances the stability of the connection between heat sinks by introducing a precise insertion design of a triangular locking tongue and a triangular slot. This design not only improves the overall structural strength of the assembled heat sink but also ensures that the heat sink remains stable and is less prone to separation or detachment when faced with external factors such as collisions and vibrations. Specifically, the triangular locking tongue is cleverly positioned at one end of the first rectangular slider and connected to the first rectangular groove via a first spring, forming a stable elastic locking mechanism. When the trapezoidal locking tongue is inserted into the insertion groove, the triangular locking tongue is pressed and retracted by the inclined surface of the trapezoidal locking tongue. After the trapezoidal locking tongue is fully inserted, the triangular locking tongue automatically pops out under the action of the first spring and firmly inserts into the triangular slot, thereby achieving a secure connection between the heat sinks.

[0015] This utility model employs an innovative sliding latch design, making the assembly and disassembly of the heat sink exceptionally simple. Users can easily connect and disconnect heat sinks without any specialized tools, simply by making a toggle operation. Structurally, the second rectangular slider is connected to a second rectangular groove via a second spring, forming a flexible sliding mechanism. Users can pull the second lever to slide the second rectangular slider, thereby controlling the extension and retraction of the trapezoidal latch. Similarly, the design of the first lever allows users to easily control the retraction and ejection of the triangular latch, thus achieving convenient assembly and disassembly of the heat sink.

[0016] In this invention, the long and short heat dissipation fins distributed on the surface of the heat sink, combined with a large-area splicing design, greatly increase the heat dissipation area, thereby improving heat dissipation efficiency. This design allows the heat sink to more effectively conduct heat from the heat-generating element to the surrounding air, ensuring the stable operation of electronic equipment. Furthermore, due to the modular design, the heat sink can be flexibly combined according to actual needs to adapt to heat-generating elements of different sizes and shapes. This design not only improves the versatility of the heat sink but also provides users with more choices and customization possibilities. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-6 This utility model provides an embodiment of a configurable heat sink, comprising a base plate 1. Two long heat sink fins 101 are fixedly connected to the middle of the upper end of the base plate 1. Two short heat sink fins 102 are fixedly connected to both the front and rear ends of the upper end of the base plate 1. Insertion slots 2 are provided on both sides of the front face of the base plate 1. A first rectangular sliding groove 201 is connected to the middle of the inner side of each of the two insertion slots 2 inside the base plate 1. A first rectangular slider 3 is slidably disposed inside the first rectangular sliding groove 201. One end of the first rectangular slider 3 extends into the insertion slot 2 and is fixedly connected to a triangular locking tongue 302. A first guide rod 202 is fixedly connected to one side of the first rectangular sliding groove 201. A guide groove 301 is provided inside the first rectangular slider 3, and one end of the first guide rod 202 is inserted into the guide groove 301. Inside the groove 301, a first spring 203 is provided on the outside of the first guide rod 202 and between one side of the first rectangular slider 3 and one side of the first rectangular groove 201. The first spring 203 pushes the first rectangular slider 3 to keep the triangular locking tongue 302 inserted into the insertion groove 2. The front ends of both sides of the upper surface of the substrate 1 are provided with first strip openings 204. The upper ends of the two first rectangular sliders 3 are fixedly connected with first paddles 303. The two first paddles 303 extend out of the upper surface of the substrate 1 through the two first strip openings 204 respectively. By pulling the first paddles 303, the first rectangular slider 3 is moved and the first spring 203 is compressed, so that the first rectangular slider 3 can drive the triangular locking tongue 302 to retract into the first rectangular groove 201.

[0026] Please see Figure 2 , Figure 3 and Figure 4 Both sides of the rear end face of the substrate 1 are provided with second rectangular slide grooves 4. A second rectangular slider 5 is slidably disposed inside the second rectangular slide groove 4. A trapezoidal locking tongue 504 is fixedly connected to the rear end of the second rectangular slider 5. A triangular slot 505 is provided on one side between the rear end of the second rectangular slider 5 and the trapezoidal locking tongue 504. A second guide rod 401 is fixedly connected to the rear end of the second rectangular slide groove 4. A telescopic groove 501 is provided in the middle of the interior of the second rectangular slider 5. The front end of the second guide rod 401 is inserted into the telescopic groove 501 and is fixedly connected to a circular limiting piece 402. A second spring 502 is provided on the outside of the second guide rod 401 between the front end of the circular limiting piece 402 and the front end of the telescopic groove 501. The second spring 502 maintains the push. The front end face of the telescopic groove 501 pushes the second rectangular slider 5 to keep the trapezoidal locking tongue 504 retracted into the second rectangular groove 4, so that when the rear end face of the substrate 1 is not connected, the trapezoidal locking tongue 504 does not protrude from the rear end face of the substrate 1, preventing the trapezoidal locking tongue 504 from interfering with the external structure after the substrate 1 is installed. The rear ends of both sides of the substrate 1 are provided with second strip openings 403. The outer sides of the two second rectangular sliders 5 are fixedly connected with second paddles 503. One end of each of the two second paddles 503 passes through the second strip opening 403 and extends out of the side end face of the substrate 1. By pulling the second paddles 503, the second rectangular sliders 5 are driven to move backward and compress the second spring 502, so that the trapezoidal locking tongue 504 can protrude from the rear end face of the substrate 1.

[0027] Please see Figure 3 , Figure 4 and Figure 6 The two substrates 1 are connected by the trapezoidal locking tongue 504 at the rear end of the second rectangular slider 5 on one substrate 1 extending out of the second rectangular slide groove 4 and inserting into the insertion groove 2 on the other substrate 1. After the trapezoidal locking tongue 504 is inserted into the insertion groove 2, the triangular locking tongue 302 is inserted into the triangular slot 505, so that the two substrates 1 are connected and locked by the insertion relationship between the triangular locking tongue 302 and the triangular slot 505.

[0028] Working principle: In use, firstly, by pulling the second lever 503, the second rectangular slider 5 moves backward along the second guide rod 401, compressing the second spring 502, causing the trapezoidal locking tongue 504 to extend outside the second rectangular slide groove 4. Then, the trapezoidal locking tongue 504 at the rear end of one substrate 1 is aligned with the insertion groove 2 at the front end of another substrate 1 and inserted. When the trapezoidal locking tongue 504 extends into the insertion groove 2, its inclined surface presses against the triangular locking tongue 302, causing the triangular locking tongue 302 to retract into the first rectangular slide groove 201, and compressing the first spring 203. When the trapezoidal locking tongue 504 is fully inserted into the insertion groove 2, the triangular slot 505 and the triangular locking tongue 302 are aligned. The restoring force of the first spring 203 pushes the first rectangular slider 3 to move, causing the triangular locking tongue 302 to insert into the triangular slot 505, locking the second rectangular slider 5 and preventing the second... The rectangular slider 5 retracts into the second rectangular groove 4, completing the connection and fixation between the two substrates 1. At this time, the long heat dissipation fins 101 and short heat dissipation fins 102 on the two substrates 1 form a large-area heat dissipation structure, which improves the heat dissipation efficiency. Furthermore, the insertion relationship between the triangular locking tongue 302 and the triangular slot 505 increases the firmness of the connection between the two substrates 1, preventing separation and detachment when subjected to external factors (such as collisions). During disassembly, by pulling the first lever 303, the first rectangular slider 3 is moved and the first spring 203 is compressed, so that the first rectangular slider 3 can drive the triangular locking tongue 302 to retract into the first rectangular groove 201, releasing the position lock of the second rectangular slider 5. The second rectangular slider 5 retracts into the second rectangular groove 4 through the restoring force of the second spring 502, thus separating the two substrates 1. The operation is convenient.

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.
