Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to an enhanced heat dissipation device. Background Technology

[0002] When CNC machine tools are working, core components such as motors and spindles continuously generate a large amount of heat, requiring timely heat dissipation. Otherwise, excessively high temperatures can easily damage the machine tool parts. Existing CNC machine tool heat dissipation devices are fixed inside a heat dissipation frame, with multiple grilles fixed in the through slots on both sides. Heat exchange occurs with the external environment through the gaps between the grilles. Over time, dust and dirt accumulate inside the grilles, causing the cross-sectional area of ​​the gaps originally used for ventilation and heat dissipation to gradually shrink, reducing ventilation and affecting heat dissipation. Since the grilles are fixed, it is inconvenient to clean the dust on the opposite surfaces of adjacent grilles. Furthermore, the structure of the heat dissipation unit is fixed, mostly an integral design. When a part of it is damaged or malfunctions, the machine needs to be stopped for replacement. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an enhanced heat dissipation device to solve the problems mentioned in the background art. This utility model has a novel structure. Through the linkage structure of the inspection door and the adjustment component, the grille can be flexibly switched between ventilation and cleaning states. When closed, it maintains ventilation gaps to ensure heat dissipation. When open, it rotates to a vertical plane to form a flat and clean surface, solving the problem of difficult-to-clean dust accumulation inside traditional fixed grilles, reducing the decrease in ventilation caused by dust accumulation, and maintaining long-term stable heat dissipation efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an enhanced heat dissipation device includes a machine tool body. A heat dissipation frame is fixedly installed on one side of the machine tool body. Two inspection doors are slidably fitted at the opening of the heat dissipation frame. Heat dissipation grooves communicating with the inner cavity are opened on both sides of the heat dissipation frame. Adjustment components that cooperate with the inspection doors are provided in the heat dissipation grooves on both sides. Multiple radiator assemblies are detachably installed inside the heat dissipation frame. A cooling fan is fixedly installed on one side of each radiator assembly.

[0005] Furthermore, two heat exchange tubes located within a heat dissipation frame are fixedly installed on the outer wall of the machine tool body, and two vertical blocks are fixedly connected to the inner bottom wall of the heat dissipation frame, with a heat exchange chamber fixedly connected above the two vertical blocks.

[0006] Furthermore, multiple connectors are fixedly connected to the upper side of each of the two heat exchange chambers, and the connectors are connected to the inner cavity of the heat exchange chamber. Two heat exchange heads are fixedly connected to the bottom of each heat exchanger assembly. The two heat exchange heads form a cold-hot correspondence with the two heat exchange chambers respectively, and the heat exchange heads are installed on the connectors accordingly.

[0007] Furthermore, two T-shaped strips are fixedly connected to the side of the two inspection doors facing the heat dissipation frame, and two T-shaped grooves are opened on the front side of the heat dissipation frame, with the T-shaped strips slidingly engaged in the T-shaped grooves.

[0008] Furthermore, the adjustment component includes multiple grid plates that are rotatably fitted in the heat dissipation slots on both sides. The multiple grid plates are arranged in an orderly manner. There are two symmetrically arranged displacement strips that slide between the upper and lower inner walls at the opening of the heat dissipation frame.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 to 8 This utility model provides a technical solution: an enhanced heat dissipation device, including a machine tool body 1, a heat dissipation frame 2 fixedly installed on one side of the machine tool body 1, two inspection doors 3 slidably fitted at the opening of the heat dissipation frame 2, heat dissipation grooves 4 communicating with the inner cavity on both sides of the heat dissipation frame 2, and adjustment components 5 cooperating with the inspection doors 3 in the heat dissipation grooves 4 on both sides. Multiple radiator groups 6 are detachably installed in the heat dissipation frame 2, and a cooling fan 7 is fixedly installed on one side of each radiator group 6. The cooling fans 7 are arranged in an orderly manner and form a ventilation through structure with the heat dissipation grooves 4 on both sides of the heat dissipation frame 2.

[0018] In this embodiment, two heat exchange tubes 8 are fixedly installed on the outer wall of the machine tool body 1, located inside the heat dissipation frame 2. Two vertical blocks 9 are fixedly connected to the inner bottom wall of the heat dissipation frame 2. A heat exchange chamber 10 is fixedly connected above the two vertical blocks 9. Multiple connectors 11 are fixedly connected to the upper side of each of the two heat exchange chambers 10, and the connectors 11 communicate with the inner cavity of the heat exchange chamber 10. Two heat exchange heads 12 are fixedly connected to the bottom of each heat exchanger group 6. The two heat exchange heads 12 form a hot-cold correspondence with the two heat exchange chambers 10 respectively, and the heat exchange heads 12 are correspondingly installed on the connectors 11. Two T-shaped strips 13 are fixedly connected to the side of the two inspection doors 3 facing the heat dissipation frame 2. Two T-shaped grooves 14 are opened on the front side of the heat dissipation frame 2, and the T-shaped strips 13 slide in the T-shaped grooves 14.

[0019] Specifically, the heat generated by the machine tool body 1 is transferred to the heat exchange chamber 10 fixed by the vertical block 9 through the heat exchange pipe 8 on the outer wall. The heat exchange chamber 10 is precisely connected to the heat exchange head 12 at the bottom of the radiator assembly 6 through the connector 11, and the heat is introduced into the radiator assembly 6. At the same time, the cooling fan 7 is started to form airflow. The external cold air enters the heat dissipation frame 2 through the gap of the grille plate 501, and after completing the heat exchange with the radiator assembly 6, it is discharged by the cooling fan 7, forming a complete heat dissipation cycle. For component replacement, the radiator assembly 6 can realize the individual disassembly and replacement of the faulty component through the detachable docking structure of the heat exchange head 12 and the connector 11.

[0020] In this embodiment, the adjustment component 5 includes multiple grille plates 501 rotatably fitted within the heat dissipation slots 4 on both sides. The multiple grille plates 501 are arranged in an orderly manner. Two symmetrically arranged displacement strips 502 slide between the upper and lower inner walls of the opening of the heat dissipation frame 2. Each of the two inspection doors 3 facing the inside of the heat dissipation slots 4 has a fixedly connected overlapping block 503 that cooperates with the two displacement strips 502. Multiple displacement grooves 504 are formed on the inner wall of the two heat dissipation slots 4 near the inspection doors 3. Multiple displacement blocks 505 that slide within the displacement grooves 504 are fixedly connected to one side of each displacement strip 502. The inner walls on both sides of the opening of the heat dissipation frame 2 are provided with connecting grooves 511. One side of each of the two displacement bars 502 is fixedly connected to the inner wall of the connecting grooves 511 on both sides. One side of the displacement block 505 is provided with a strip groove 506. The two sides of the grille plate 501 are fixedly connected with sliding columns 507 near their edges. The sliding columns 507 slide and rotate within the strip grooves 506. The middle of both sides of the grille plate 501 is fixedly connected with fixing columns 508. The inner walls on both sides of the heat dissipation slot 4 are provided with fixing grooves 510. The fixing columns 508 rotate within the fixing grooves 510.

[0021] Specifically, the inspection door 3 opens and closes by sliding the T-shaped strip 13 with the T-shaped groove 14 of the heat dissipation frame 2. When closed, the overlapping block 503 separates from the displacement strip 502. The elastic force of the spring 509 drives the displacement strip 502 and the displacement block 505 to slide along the displacement groove 504. The strip groove 506 of the displacement block 505 drives the grille 501 to rotate around the fixed column 508 through the sliding column 507, so that the grille 501 forms parallel and orderly ventilation gaps in the heat dissipation slot 4. When the inspection door 3 is opened, the overlapping block 503 pushes the displacement strip 502 to compress the spring 509, causing the grille 501 to rotate to a vertical plane, which is convenient for cleaning.

[0022] When the device is in use, the two inspection doors 3 are closed by the inner T-shaped strips 13 embedded in the T-shaped grooves 14 on the front side of the heat dissipation frame 2. The overlapping block 503 separates from the displacement strip 502. Through the force of the spring 509, the displacement strip 502 drives the displacement block 505 to slide along the displacement groove 504 of the heat dissipation groove 4. The strip groove 506 of the displacement block 505 drives the grid plate 501 to rotate around the fixed column 508 through the sliding column 507, so that multiple grid plates 501 are arranged in parallel and orderly in the heat dissipation groove 4 to form ventilation gaps. When the CNC machine tool is running, the heat of the machine tool body 1 is transferred through the heat exchange pipe 8 on the outer wall to the heat exchange chamber 10 fixed by the upright block 9 in the heat dissipation frame 2. The heat exchange chamber 10 is connected to the heat exchange head 12 at the bottom of the heat exchanger group 6 through the connector 11, and the heat is introduced into the heat exchanger group 6. At the same time, the cooling fan 7 is started, and the external cold air The heat enters the heat dissipation frame 2 through the gaps in the grille 501, exchanges heat with the radiator assembly 6, and is then discharged by the cooling fan 7, completing the heat dissipation cycle. When the grille needs to be cleaned, the inspection door 3 is pulled open along the T-slot 14. At this time, the overlapping block 503 on the inspection door 3 pushes the displacement bar 502 of the adjustment component 5 to move inward to the connecting groove 511, compressing the spring 509. The displacement bar 502 drives the displacement block 505 to slide and rotate multiple grille plates 501, so that one side of multiple grille plates 501 on both sides rotates to a vertical state. Multiple vertical grille plates 501 form a plane, which facilitates the cleaning of dust on their surface. If the radiator assembly 6 or the cooling fan 7 malfunctions, after opening the inspection door 3, disconnect the heat exchange head 12 of the faulty component from the connector 11, disassemble and replace the new component, reconnect it, and close the inspection door 3 to restore operation.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
