Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation equipment technology, and in particular to a heat sink that is easy to clean. Background Technology
[0002] Heat sinks are indispensable heat dissipation components in various electronic devices, enhancing heat dissipation through forced air convection. However, during long-term operation, the fan blades and fins of the heat sink accumulate a large amount of dust, which not only reduces heat dissipation efficiency and increases operating noise but may also affect the lifespan of the equipment. Therefore, regular cleaning of heat sinks is crucial.
[0003] In the prior art, such as Chinese utility model patent with publication number CN222633302U, a radiator that is easy to clean is disclosed. This solution hinges the cooling fan to the radiator body and uses structures such as limiting posts and fixing bolts to allow the cooling fan to be flipped open relative to the radiator body, thereby facilitating the cleaning of the area between the radiator body and the cooling fan.
[0004] However, this solution still has the following shortcomings: the cooling fan itself is a single unit, with its blades fixed to the motor and cannot be disassembled. During cleaning, the front and back of the blades, especially the root area where they connect to the motor, are difficult to clean thoroughly, and dust easily remains. Furthermore, this solution uses two relatively independent plug-in or locking mechanisms to secure the cooling fan. When it is necessary to open the cooling fan for cleaning, both mechanisms must be operated separately, which is relatively cumbersome and inconvenient. Therefore, a radiator that is easy to clean is needed to meet people's needs. Utility Model Content
[0005] The purpose of this invention is to provide a radiator that is easy to clean, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a radiator that is easy to clean, comprising a radiator body, a cooling fan, and two sets of flexible plug-in mechanisms. One end of the cooling fan is connected to the radiator body via a hinge, and the other end is releasably connected via the two sets of flexible plug-in mechanisms. By pressing or actuating the drive rod of the flexible plug-in mechanism, the locking of that end of the cooling fan can be released, allowing it to flip open around the hinge point, thereby exposing the fins of the radiator body and the inner side of the cooling fan for easy cleaning.
[0007] The cooling fan consists of an outer frame, a motor fixedly installed within the outer frame, and fan blades driven by the motor. Its innovation lies in the connection structure between the fan blades and the motor output shaft. A first support plate is fixedly mounted on the motor output shaft. A rod is vertically fixed to the first support plate. A second support plate, which can slide along its axial direction, is fitted onto the outer wall of the rod. A spring is provided between the second and first support plates, and this spring constantly applies a force to the second support plate, causing it to move away from the first support plate.
[0008] A through hole is formed in the center of the fan blade. During assembly, the end of the insert rod can be inserted into this through hole. A retaining rod is radially rotatably connected inside the insert rod. When the insert rod is inserted into the through hole of the fan blade, the retaining rod can rotate to the unfolded state, so that it spans across the surface of the fan blade opposite to the second support plate, thereby axially restricting the fan blade from detaching. At this time, under the action of the spring, the second support plate is pressed tightly against the other side of the fan blade, and together with the unfolded retaining rod, clamps and fixes the fan blade.
[0009] Both sets of elastic plug-in mechanisms have a connecting rod rotatably connected to their drive rods. The other ends of these two connecting rods are rotatably connected to a guide block. When the operator presses both drive rods inward simultaneously, the guide block can be moved in a specific direction through the transmission of the connecting rods. This linkage design allows for simultaneous control of both elastic plug-in mechanisms with a single action, simplifying operation.
[0010] The beneficial effects of this utility model are: This invention utilizes a combination of a plug rod, spring, second support plate, and rotatable locking rod to achieve quick installation and disassembly of the fan blades and motor. Users simply rotate the locking rod to detach it from the fan blades, allowing for easy and thorough cleaning. This solves the problem of dust accumulation in hard-to-clean areas such as the fan blade base. With the fan blades installed, the preload provided by the spring and the limiting effect of the locking rod combine to ensure the stability of the fan blades during operation, preventing them from loosening or falling off. The hinged and flexible plug-in mechanism between the cooling fan and the radiator body also ensures the stability of the overall structure.
[0011] This invention connects two independent, elastic plug-in mechanisms using a linkage mechanism. Users can release the lock on one end of the cooling fan by simultaneously pressing both drive levers with one hand, allowing it to flip open. This design combines two separate operation steps into one, significantly improving ease of use and efficiency. Without significantly increasing cost or structural complexity, it effectively solves the problem of deep cleaning of heat sinks, making it particularly suitable for heat sinks in computers, servers, communication equipment, and other fields requiring regular maintenance, and possesses high market potential.

[0014] 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.
[0015] Reference Figure 1-4 A radiator that is easy to clean mainly includes a radiator body 1, a cooling fan 2, and two sets of symmetrically arranged flexible plug-in mechanisms 3.
[0016] One end of the cooling fan 2 is hinged to one side of the radiator body 1 via a hinge or pivot. The other end of the cooling fan 2 is detachably connected to the other side wall of the radiator body 1 via two sets of elastic plug-in mechanisms 3. The elastic plug-in mechanism 3 can adopt a button-type snap-fit structure commonly used in the prior art, which usually has a return spring inside. When the two drive rods are pressed inward at the same time, the latch retracts, and the left end of the cooling fan 2 can be disengaged; when the drive rods are released, under the action of the return spring, the latch pops out and engages with the corresponding snap-fit hole in the radiator body 1 to achieve locking.
[0017] The cooling fan 2 includes an outer frame 4. A motor 5 is fixedly mounted at the center of the outer frame 4. The output shaft of the motor 5 faces the mounting side of the fan blades 6. A circular first support plate 7 is fixed to the end of the output shaft. A cylindrical insert 8 is vertically fixed to the center of the first support plate 7. A tubular or annular second support plate 9 is slidably fitted onto the insert 8. A spring 10 is fitted onto the insert 8 and compressed between the first support plate 7 and the second support plate 9.
[0018] A through hole 11 is formed in the center of the fan blade 6. Preferably, a rubber ring (not shown separately in the figure) is embedded in the inner wall of the through hole 11 to increase friction and tightness with the insertion rod 8 and reduce shaking. On the end face of the fan blade 6 facing the second support plate 9, an annular positioning groove (not shown in the figure) is formed around the through hole 11, into which the second support plate 9 can be inserted for initial positioning. On the other end face of the fan blade 6 away from the second support plate 9, a radial groove 16 is formed.
[0019] The end of the insertion rod 8 has an axial slot 15 that extends through both ends of the side wall of the insertion rod 8. A retaining rod 12 is rotatably connected to the slot 15 via a pin, and the length of the retaining rod 12 is less than the length of the slot 15, allowing it to be completely retracted into the slot 15. When it is necessary to install the fan blade 6, first rotate the retaining rod 12 to a position parallel to the axis of the insertion rod 8 (i.e., retracted into the slot 15), then align the insertion rod 8 and insert it into the through hole 11 of the fan blade 6. After the insertion rod 8 is inserted, rotate the retaining rod 12, making it rotate about 90 degrees, so that it unfolds horizontally and falls precisely into the retaining groove 16 on the back of the fan blade 6. At this time, under the elastic force of the spring 10, the second support plate 9 tightly abuts against the front of the fan blade 6 (the side closer to the motor 5), while the unfolded retaining rod 12 is locked in the retaining groove 16 on the back of the fan blade 6, thus firmly clamping and fixing the fan blade 6. To disassemble the fan blade 6, simply reverse the operation.
[0020] To simplify the opening and closing operation of the cooling fan 2, each of the two sets of flexible plug-in mechanisms 3 has a connecting rod 13 hinged to its drive rod. The other ends of the two connecting rods 13 are hinged to a guide block 14. A guide rod 17 is fixedly installed on the left outer wall of the outer frame 4, and the guide block 14 is slidably fitted onto the guide rod 17. When the user pinches the two drive rods simultaneously with their thumb and forefinger, the two connecting rods 13 will pull the guide block 14 to slide to the right along the guide rod 17. This linkage mechanism ensures that the two drive rods can move synchronously, enabling the cooling fan 2 to be unlocked with a single-handed, one-step operation.
[0021] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
